Description

  The present invention relates to a deodorizing member that deodorizes the odor by passing a gas having an odor such as excrement, and a container with the deodorizing member provided with the deodorizing member.

  Stoma may be constructed on the body surface as a treatment for diseases such as digestive organs and urinary organs. Since the stoma cannot self-control excretion, it is necessary to wear a stoma brace that stores the excrement. In addition to solids and fluids, gas is discharged from the body in the stoma, so it is necessary to remove this gas from the stoma appropriately. In order to avoid odor leaking with the gas during the degassing, a deodorizing filter is installed in a part of the stoma device, and the gas is extracted through the deodorizing filter. Patent document 1 is mentioned as a technical document regarding the stoma appliance provided with the deodorizing filter.

JP 2002-85439 A

  However, the conventional deodorizing filter for stoma equipment has low deodorizing effect, especially when the stoma equipment is compressed and forcibly degassed, because the flow rate of exhausted gas is large, etc. There was a tendency for the period from the replacement to a new stoma to shortage of deodorization performance. For this reason, the user was forced to be inconvenient, such as having trouble with the location and timing of degassing until the next time the appliance was replaced. From the viewpoint of improving the quality of life of the stoma wearer, it would be meaningful if a deodorizing member capable of exhibiting a high level of deodorizing effect with good sustainability against forced exhaust from the stoma brace is provided.

  The present invention has been created in view of the above circumstances, and an object thereof is to provide a deodorizing member having a high deodorizing effect even for forced exhaust. Another related object is to provide a stoma appliance or other storage container provided with the deodorizing member.

  According to this specification, the deodorizing member which deodorizes this odor by passing the gas which has an odor inside is provided. The deodorizing member includes a cylindrical deodorizing container. The deodorizing container has an inlet and an outlet for the gas at one end and the other end, and defines a gas flow path from the inlet to the outlet. The deodorizing member has a deodorizing particle filling portion provided over at least a part of the length of the gas flow path. The deodorant particle filling part is composed of unsupported deodorant particles. 75% by weight or more of the deodorant particles constituting the deodorant particle filling portion has a particle diameter in the range of 50 μm or more and 1000 μm or less. The deodorizing member typically further includes a breathable stopper disposed on the upstream side and the downstream side of the deodorant particle filling unit. The deodorizing member has a Gurley air permeability of 100 seconds / 100 cc or less.

  In the deodorizing member configured as described above, since the deodorizing member filling portion is provided in the gas flow path formed in the cylindrical deodorizing container, the odorous gas (deodorizing target gas) is distributed. Good sex. Moreover, since the said deodorizing member filling part is comprised by the non-carrying deodorizing particle (namely, it is not carry | supported by support | carriers, such as a nonwoven fabric), this deodorizing particle can be utilized efficiently. Moreover, since 75% by weight or more of the deodorant particles constituting the deodorant particle filling part are in the range of 50 μm or more and 1000 μm or less in particle diameter, it is not carried without excessively impeding the flow of the gas to be deodorized. It is possible to maintain a state in which the deodorizing particles are properly filled in the deodorizing member filling portion. As the deodorizing particles, for example, deodorizing particles containing activated carbon particles as a main component (that is, a component contained in excess of 50% by weight) can be preferably used. Since the said deodorizing member is comprised so that the value of a Gurley type air permeability may become below predetermined, it can process a deodorizing object gas rapidly. Accordingly, for example, the present invention is preferably applied to a usage mode in which a person compressing a container to which the deodorizing member is attached forcibly exhausts the gas in the container through the deodorizing member and deodorizes the container. Can do.

  The gas channel preferably has an aspect ratio of 5 or less in a cross-sectional shape (opening shape) orthogonal to the gas channel. By using the gas flow path having such a shape, it becomes easy to appropriately fill the gas flow path with unsupported deodorant particles. The cross-sectional shape is not particularly limited, and can be appropriately selected from, for example, a circle, an ellipse, a quadrangle, a hexagon, an octagon, and the like.

  It is preferable that the length of the deodorant particle filling portion is 1.5 times or more the circle-converted diameter based on the opening area of the gas flow path in a cross section orthogonal to the gas flow path. By comprising in this way, the deodorizing object gas which passes a gas flow path can fully be made to contact with a deodorizing particle, and a high deodorizing effect can be exhibited. The deodorizing member disclosed herein has an aspect ratio of a cross-sectional shape (opening shape) orthogonal to the gas flow path of 5 or less, and the length of the deodorized particle filling portion is 1. It can be preferably implemented in an embodiment that is 5 times or more.

  In a preferred aspect, a cushion material for compressing the deodorant particle filling portion is disposed in the gas flow path. As a result, it is possible to maintain the state in which the unsupported deodorizing particles are appropriately filled in the gas flow path, and to increase the durability of the deodorizing effect. As the cushion material, one or both of the stoppers disposed on the upstream side and the downstream side of the deodorant particle filling portion may be used, or a cushion material different from the stopper may be disposed, You may use together.

  According to this specification, the container with a deodorizing member provided with the storage container comprised so that accommodation of an odor generating source and any of the deodorizing members disclosed here was provided. The said container is comprised so that the content containing an odor generating source can be compressed and the gas in this container can be extruded to the exterior of the said container. The deodorizing member is disposed in the gas discharge path. According to such a container with a deodorizing member, the volume containing the odor generating source can be compressed to reduce its volume. Normally, if the contents containing the odor source are inadvertently compressed, the gas containing the odor may be released, which may cause discomfort to the worker and the surrounding people. According to the container disclosed here, the odor The gas containing can be discharged through the deodorizing member and then discharged out of the container.

  In a preferred aspect of the container with the deodorizing member, the deodorizing member is along the wall surface of the containing container, that is, with the outer surface of the deodorizing member (typically, the side surface of the deodorizing container) along the wall. Has been placed. It is preferable to arrange | position so that the end surface by the side of the said entrance of the said deodorizing member may become non-parallel to the said wall surface. By arranging the deodorizing member in this way, it is difficult to cause a situation in which the inlet side end face is covered with the contents of the storage container (for example, solid or liquid excretion discharged from the human body). The gas flowability of the deodorizing member incorporated in the container with the deodorizing member tends to be easily maintained in a good state.

In a preferred aspect of the container with the deodorizing member, an oil-repellent polytetrafluoroethylene (PTFE) porous film can be disposed between the inlet of the deodorizing container and the contents of the storage container. Accordingly, it is possible to suitably prevent or suppress a situation where the inlet side end surface of the deodorizing member is covered with the contents of the storage container.
In another preferred embodiment, an oil-repellent porous PTFE membrane can be disposed between the outlet of the deodorizing container and the outside of the deodorizing container. For this reason, for example, even when water is applied to the deodorizing container, the oil-repellent PTFE porous film exhibits good water repellency, so that the outlet of the deodorizing container does not get wet. Therefore, there is no need to provide an outlet cover or the like separate from the oil-repellent PTFE porous membrane. In addition, the oil-repellent PTFE porous membrane can be dried quickly because the water covering the membrane surface is repelled by water even when splashed with water, so that the outlet side end surface is covered with the water membrane. Can be prevented or suppressed.
In these embodiments, the oil-repellent PTFE porous membrane may be disposed, for example, so as to cover the inlet or outlet of the deodorizing container as a component of the deodorizing member, and separately from the deodorizing member. Further, the deodorizing member may be disposed between the inlet side end surface and the storage container, or between the outlet side end surface of the deodorizing member and the storage container.

  In a preferred embodiment of the container with the deodorizing member, a deodorizing material for deodorizing at least one of ammonia and amines may be disposed in the gas discharge path and outside the deodorizing particle filling portion. it can. As a result, ammonia odor and / or amine odor can be efficiently removed.

  As a preferable example of the container with the deodorizing member, a stoma device is exemplified. By applying the technique disclosed herein, the exhausted gas can be accurately deodorized even when the stoma is pressed and the gas accumulated in the stoma is forcibly exhausted, and the It is possible to realize a stoma device with a deodorizing member having excellent deodorizing effect.

Can be understood by those skilled in the art. The present invention can be carried out based on the contents disclosed in this specification and common technical knowledge in the field. Further, in the following drawings, members / parts having the same action may be described with the same reference numerals, and overlapping descriptions may be omitted or simplified. In addition, the embodiments described in the drawings are schematically illustrated in order to clearly explain the present invention, and do not necessarily accurately represent the size and scale of a product actually provided.

<First Embodiment>
(Deodorant member)
FIG. 1 is a schematic perspective view showing a deodorizing member according to the first embodiment. FIG. 2 is a schematic perspective view showing a container (stoma appliance) with a deodorizing member provided with the deodorizing member shown in FIG. The deodorizing member and the container with the deodorizing member of this embodiment will be described with reference to the drawings.

  As shown in FIG. 1, the deodorizing member 10 according to the present embodiment includes a cylindrical deodorizing container 12 having one end 12A and the other end 12B opened. Inside the deodorizing container 12, a gas flow path 13 extending from one end 12A to the other end 12B is defined. A deodorizing particle filling unit 14 is provided in at least a part of the length of the gas flow path 13. The deodorant particle filling unit 14 of the present embodiment is continuously provided from one end 12A to slightly before the other end 12B. The deodorant particle filling unit 14 is composed of unsupported deodorant particles 14a. That is, the deodorant particles 14a are not carried (fixed) on a carrier such as a fiber aggregate such as a nonwoven fabric or a porous material such as a sponge, but are filled in the gas flow path 13 in the state of particles, and are consumed. The odor particle filling part 14 is comprised. As the deodorizing particle 14a in this embodiment, the deodorizing particle which has as a main component the activated carbon particle prepared in the granular form of the particle diameter of the range of 100 micrometers-500 micrometers can be employ | adopted preferably, for example.

  Breathable stoppers 16 and 17 are arranged on the upstream side and the downstream side of the deodorant particle filling unit 14. In the deodorizing member 10 of the present embodiment, the upstream stopper 16 is configured by a breathable pressure-sensitive adhesive sheet that is attached to the deodorizing container 12 so as to cover the opening (gas inlet) of one end 12A. The downstream stopper 17 covers the opening (gas outlet) of the other end 12 </ b> B and is attached to the deodorizing container 12. It is comprised from the breathable cushioning material 17b arrange | positioned between the odor particle filling part 14. FIG. The cushion material 17b is lightly compressed between the inner wall of the deodorant container 12, the air-permeable adhesive sheet 17a, and the deodorant particle filling part 14, and thereby the deodorant particles 14a constituting the deodorant particle filling part 14 are compressed. The filling state is maintained well. As the cushion material 17b in the present embodiment, for example, a polyester foam having open cells can be preferably employed.

  As the breathable pressure-sensitive adhesive sheet (stopper) 16 covering the one end 12A of the deodorizing container 12, for example, a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer on one side of a porous polyolefin base material can be used. As a commercial product of such a breathable pressure-sensitive adhesive sheet, a trade name “Nitoru AP-0300” manufactured by Nitto Lifetech Co., Ltd. may be mentioned. The same thing can be used also as the air permeable adhesive sheet 17 which covers the other end 12B of the deodorizing container 12. FIG.

  In the deodorant member 10 configured in this manner, the deodorant particles 14a constituting the deodorant particle filling unit 14 are not carried, and therefore the deodorant particles 14a can be efficiently used for deodorization. For example, it is possible to avoid an event in which the activity of the deodorant particles decreases due to an adhesive or the like for fixing the deodorant particles to a carrier such as a nonwoven fabric. Further, by making the carrier unnecessary, the arrangement density of the deodorant particles 14a in the gas flow path 13 can be increased, and the inside of the gas flow path 13 can be used more efficiently as a deodorant space. This can advantageously contribute to the downsizing of the deodorizing member 10 and the improvement in the sustainability of the deodorizing effect.

  Here, if the unloaded deodorant particle filling state is loosened in a part of the deodorant particle filling part, the deodorant target gas concentrates on the part, and the deodorant target gas is not sufficiently in contact with the deodorant particle. A situation where the deodorizing member 10 passes may occur. In the present embodiment, the breathable stoppers 16 and 17 are arranged on the upstream side and the downstream side of the deodorant particle filling unit 14, so that the deodorant particles 14 a are properly filled in the deodorant particle filling unit 14. Maintainability is improved. By configuring one or both of the stoppers on the upstream side and the downstream side to exhibit cushioning properties, loosening of the deodorized particles can be more suitably suppressed. In the present embodiment, the above-described configuration is realized by the downstream stopper 17 including the cushion material 17b.

  Since the deodorizing member 10 of this embodiment is provided with the deodorizing member filling part 14 in the gas flow path 13 formed in the inside of the cylindrical deodorizing container 12, the deodorizing object that passes through the gas flow path 13 is provided. It is easy to keep the gas flow resistance low. In addition, such a cylindrical shape easily spreads the deodorization target gas introduced into the deodorization container 12 from the one end 12 </ b> A in the radial direction of the gas flow path 13. The particles 14a can be used effectively.

  In this specification, deodorization is a concept including deodorization and deodorization. In addition, as the deodorizing particles in the technology disclosed herein, a known deodorizing material particle capable of deodorizing a gas containing the odor component is appropriately selected according to the type of the odor component to be deodorized. Can be used. The type of the deodorizing material is not particularly limited as long as it can be prepared in the form of particles. For example, a physically acting deodorant that physically removes odor components by trapping (adsorption, inclusion, etc.); removing or decomposing (reforming) odor components by chemical reactions such as oxidation, reduction, and neutralization Chemically acting deodorant that removes or decomposes odorous components through a combination of physical traps and chemical reactions; metal catalyst, etc. Any of a deodorizing material having a catalytic action that decomposes odorous substances by the catalytic action of the above can be used. The deodorizing material which exhibits a deodorizing effect by the intermediate | middle or combined effect | action of these may be sufficient. A deodorant material can be used individually by 1 type or in combination of 2 or more types.

  As the deodorizing particles in the technology disclosed herein, particles of physical deodorizing materials such as activated carbon, silica gel, alumina gel, activated clay, zeolite, cyclodextrin are preferably employed because they are suitable for use in the form of particles. obtain. Among them, activated carbon particles are preferable as deodorant particles. For example, activated carbon particles can be preferably employed in a deodorizing member used by being incorporated in a stoma appliance. Although not particularly limited, the ratio of the activated carbon particles in the deodorant particles to be used is, for example, more than 50% by weight, preferably 70% by weight or more, more preferably 90% by weight or more (for example, 95% by weight or more). It is. The activated carbon particles may be substantially 100% by weight (typically 98% by weight or more) of the deodorant particles.

  The particle shape of the deodorant particles is not particularly limited. From the viewpoint of easy formation and maintenance of a uniform filling state and excellent gas flowability, generally spherical deodorant particles can be preferably used. The deodorant particles may be in the form of primary particles or secondary particles. Since the shape and size of the particles can be easily managed, deodorized particles in the form of primary particles can be preferably used. As the deodorizing particles in the technology disclosed herein, for example, primary particles (for example, activated carbon particles) prepared in a granular shape within a predetermined size range can be preferably used.

  The size of the deodorizing particles can be set so that appropriate gas flowability is exhibited in the deodorizing member. As the filled deodorant particles of the present embodiment, deodorant particles (for example, activated carbon particles) having a particle diameter of 50 μm or more, preferably 100 μm or more are suitably used. By this, the deodorizing member which shows favorable gas flowability is realizable. The upper limit of the particle size of the deodorant particles is not particularly limited, but from the viewpoint of increasing the contact efficiency with the gas to be deodorized, deodorant particles having a particle size of 1000 μm or less are usually preferable. For example, deodorant particles having a particle size in the range of 100 μm to 500 μm can be preferably used. The technique disclosed herein can be preferably implemented in an embodiment in which 75% by weight or more of the deodorant particles constituting the deodorant particle filling portion has a particle diameter of 100 μm or more and 500 μm or less. In addition, when there are many coarse deodorant particles, filling unevenness occurs, and when there are many excessive deodorant particles, gaps between the deodorant particles can be clogged and the gas flowability tends to decrease. Preferably used are deodorant particles having a particle size of less than 100 μm and particles substantially not exceeding 500 μm (for example, deodorant particles having a content of such particles of less than 3%, typically less than 1%). be able to. The average particle size of the deodorant particles is not particularly limited. For example, deodorant particles having an average particle diameter of about 100 μm to 500 μm, preferably about 150 μm to 300 μm can be preferably used.

  The gas flowability of the deodorant member can be represented by, for example, a Gurley type air permeability (sometimes referred to as air permeability resistance, hereinafter simply referred to as “air permeability”). The air permeability of the deodorant member disclosed herein is typically about 100 seconds / 100 cc or less, preferably about 50 seconds / 100 cc or less, more preferably about 25 seconds / 100 cc or less. The air permeability can be preferably applied to, for example, a deodorizing member that is assumed to be used in such a manner that the gas accumulated in the stoma appliance is compressed and forcibly exhausted. In one embodiment, the air permeability of the deodorizing member may be about 15 seconds / 100 cc or less (for example, about 10 seconds / 100 cc or less). The lower limit of the air permeability of the deodorant member is not particularly limited. From the viewpoint of easily improving the deodorizing effect, in one aspect, the air permeability of the deodorizing member is, for example, 0.5 sec / 100 cc or more (preferably 1 sec / 100 cc or more, for example, 3 sec / 100 cc or more). it can.

  The Gurley type air permeability in the technology disclosed herein can be measured using a B-shaped Gurley tester defined in JIS P 8117. If necessary, an auxiliary jig for hermetically connecting the Gurley tester and the measurement sample may be used. When using an auxiliary jig, the test sample is not connected and only the auxiliary jig is connected to the Gurley tester, and the test is performed to increase the Gurley air permeability by the auxiliary jig (blank). And the value obtained by subtracting the blank from the measurement value of the measurement sample connected to the Gurley testing machine via the auxiliary jig is defined as the Gurley air permeability of the measurement sample.

In the technology disclosed herein, as a breathable stopper disposed on the upstream side and the downstream side of the deodorant particle filling portion, a known material that is breathable and can block the movement of the deodorant particles is used. Can be used. Examples of materials that can be used as the stopper include, for example, fiber aggregates such as nonwoven fabric, cloth, cotton, glass wool, and metal mesh; porous resin molded bodies such as porous resin films and porous resin foams; And the like. Since the shape flexibility is excellent, a fiber aggregate or a porous resin molded body can be preferably used as the stopper. Examples of the porous resin foam include polyester, polyether, polyurethane foam, polyethylene foam, polychloroprene foam and the like. From the viewpoint of breathability, a foam (for example, polyester foam) having open cells is preferable. One or both of the stoppers on the upstream side and the downstream side of the deodorant particle filling unit may include two or more members (for example, a porous resin film and cotton). In the embodiment shown in FIG. 1, two members, a breathable pressure-sensitive adhesive sheet 17a and a cushion material 17b, are used as a downstream stopper.
Also, polypropylene or rayon with breathable non-woven fabric or cotton having odor gas adsorption effect is placed as a stopper in the flow path of the deodorant member to deodorize the target odor gas more strongly, or by deodorant particles It is also possible to remove odorous gas that is different from the object to be deodorized. For example, a nanofilter manufactured by Teijin Limited, “Adsep (registered trademark)” manufactured by Nippon Filcon Co., Ltd., or the like can be used.

  The stopper is on the upstream side or downstream side of the deodorant particle filling part, and is used to prevent looseness of the deodorant particles constituting the deodorant particle filling part and to move (spill) out of the deodorant particle filling part. What is necessary is just to arrange | position so that it can suppress, and an arrangement position and an arrangement | positioning aspect are not specifically limited. As a suitable example of the arrangement | positioning aspect of a stopper, the aspect arrange | positioned in the gas flow path of the upstream or downstream of a deodorizing particle filling part, and the aspect arrange | positioned covering the one end or the other end of a deodorizing container are mentioned. When using a stopper that also serves as a cushion material, it is usually preferable to dispose the stopper in the gas flow path. As the stopper also serving as a cushioning material, the above-described fiber aggregate and porous resin molded body can be preferably used. The cushion material may be disposed only on one of the upstream side and the downstream side of the deodorant particle filling portion as in the example illustrated in FIG. 1 or may be disposed on both. From the viewpoint of increasing the amount of deodorizing particles that can be accommodated in the gas flow path and improving the sustainability of the deodorizing effect, it is preferable to dispose the cushioning material only in one of them.

  As the stopper disposed so as to cover one end or the other end of the deodorizing container, a porous resin film, cloth, nonwoven fabric or the like can be preferably used. From the viewpoint of suppressing the gas flowability of the deodorizing member from being lowered by disposing the stopper, the stopper can be measured using an air permeability (if necessary, an auxiliary jig as described above. ) Of 5 seconds / 100 cc or less can be preferably employed.

  In a deodorizing member in which a moisture or oil can be contacted with one end or the other end of the deodorizing container, the moisture or oil directly contacts the deodorizing particles to reduce the activity of the deodorizing particles. From the viewpoint of preventing this, it is preferable to cover the end portion on the side where they can be contacted with a porous resin film. The deodorizing member disclosed here can be preferably implemented, for example, in a form in which at least an end of the deodorizing container on the gas inlet side of the deodorizing container is covered with a porous resin film. Preferable examples of the porous resin film include a porous polytetrafluoroethylene (PTFE) resin sheet and a porous polyolefin resin sheet (for example, a porous polyethylene resin sheet).

  In one embodiment of the technology disclosed herein, a PTFE porous membrane can be preferably used as the porous resin film. For example, a PTFE porous membrane having a collection efficiency of 50% or more at a target particle size of 0.3 to 0.5 μm is preferable. Thereby, even if water is temporarily in contact with the porous resin film covering one end or the other end of the deodorizing container, the water is prevented from spreading on the porous resin film to form a liquid film, Good gas flowability can be maintained. In the PTFE porous membrane, for example, a nonwoven fabric made of a thermoplastic resin such as polyolefin (for example, polypropylene) may be laminated on one surface of the membrane in order to impart strength and heat weldability.

  In one embodiment, a PTFE porous membrane that exhibits oil repellency in addition to water repellency can be preferably employed. By using such an oil-repellent PTFE porous membrane, even when a liquid containing oil is temporarily in contact with the porous resin film covering one end or the other end of the deodorizing container, the oil content is not reduced. It is possible to suppress the formation of a liquid film (oil film) spreading on the upper side and maintain good gas flowability. As a preferred example of the oil repellent PTFE porous membrane, a PTFE porous membrane exhibiting oil repellency having an oil repellency of 12 or more can be mentioned. The oil repellency can be measured by carrying out an oil repellency test according to the “fabric-oil repellency—hydrocarbon resistance test” defined in ISO 14419. Specifically, n-dodecane (12 carbon atoms) is dropped as a droplet having a diameter of about 5 mm on the surface of the porous PTFE membrane to be measured using a pipette. Thirty seconds after the dropping, the presence or absence of penetration of the droplet into the PTFE porous membrane is confirmed by visual observation, and if no penetration is observed, the oil repellency is determined to be 12 or more. The phrase “droplet permeation is observed” means that the droplet is absorbed by the porous film or a change in the color tone of the porous film due to the permeation of the droplet is recognized. As the PTFE porous membrane having an oil repellency of 12 or more, a trade name “TEMISH” manufactured by Nitto Denko Corporation can be preferably used.

  The stopper may include a deodorizing material as a constituent material or may be configured to exhibit the same or different deodorizing action as the deodorizing particles by supporting the deodorizing material. In one embodiment, a stopper having an ammonia deodorizing material (for example, a stopper in which an ammonia deodorizing material is supported on the above-described fiber assembly, porous resin molded body, or porous inorganic molded body) can be preferably used. As the ammonia deodorizing material, a known material known to exhibit a deodorizing effect on ammonia, such as a divalent iron compound or alum, can be appropriately selected and used. For example, a stopper having an ammonia deodorizing material can be preferably used in a deodorizing member incorporated and used in a stoma appliance.

  Although not particularly limited, a stopper having a high particle collection efficiency can be preferably used as the stopper. According to such a stopper, even when the deodorant particles are broken or chipped due to an external force or the like, it is possible to prevent the deodorant particles from leaking through the stopper. Further, by disposing such a stopper on the upstream side of the deodorant particle filling unit, fine particles that can be contained in the deodorant target gas are prevented from reaching the deodorant member filling unit, and the deodorant member filling unit Clogging can be suppressed. For example, the collection efficiency at a target particle diameter of 10 μm based on JIS B9927 is 90% or more; and the collection efficiency at a target particle diameter of 0.3 to 0.5 μm is 50% or more; A filling stopper (for example, a porous resin sheet) can be used.

  As the stopper, it is preferable to use a stopper that emits less volatile components. By this, the phenomenon in which the volatile component derived from a stopper deactivates a deodorizing particle can be suppressed, and a deodorizing particle can be utilized more effectively. For example, as an example of a breathable pressure-sensitive adhesive sheet with a small amount of volatile components emitted, the above-mentioned trade name “Nito Through AP-0300” can be preferably employed.

The deodorizing member 10 shown in FIG. 1 can be preferably used as a component of a container (stoma appliance) 100 with a deodorizing member as shown in FIG. This stoma device 100 is provided with a bag-like container 110 having an inner film and an outer film, and the inner film side is used as the body side, similarly to the known stoma device. A face plate 120 is attached to the inner film, and an opening 122 is formed at the center of the face plate 120. The stoma device 100 is used by aligning the opening 122 of the face plate 120 and the opening formed in the human body and attaching the face plate 120 to the human body with an adhesive. Excrement (odor generating source) discharged from the opening of the human body is introduced into the storage container 110 through the opening 122 of the face plate 120 and stored. The maximum internal capacity of the storage container 110 is generally 700 cc to 900 cc. However, in order to use the stoma appliance 100 comfortably and comfortably, the amount of gas stored in the storage container 110 should be suppressed to approximately 300 cc or less. desirable.

The stoma device 100 is provided with a through-hole 110 </ b> B used for discharging the gas on the wall surface 110 </ b> A of the storage container 110. In the stoma device 100 of the present embodiment, a through hole 110B is formed at the right end (left end when viewed from the user) of the upper end in a state where the stoma device 100 is mounted on the user's body. The deodorizing member 10 described above is attached to the through hole 110B. More specifically, the deodorizing member 10 is disposed at the upper inner end of the storage container 110 such that the axis of the cylindrical deodorizing container 12 is substantially parallel to the wall surface 110A. The deodorizing member 10 is disposed such that the end surface on the gas inlet side (upstream side) thereof is not parallel to the wall surface 110A. The angle formed by the gas inlet side end face of the deodorizing member 10 and the wall surface 110A is preferably 30 degrees or more, more preferably 45 degrees or more, for example, 60 degrees or more. In the present embodiment, the angle formed between the gas inlet side end surface of the deodorizing member 10 and the wall surface 110A is approximately 90 degrees.
Immediately below the deodorizing container 12, a heat seal part 110C is formed by thermally welding the inner film and the outer film. The stoma device 100 further includes heat seal portions 110D and 110E formed by thermally welding the wall surface 110A of the storage container 110 on the outer periphery of the deodorizing container 12. The deodorizing member 10 is fixed to the storage container 110 by these heat seal portions 110C, 110D, and 110E.

  The user of the stoma device 100 performs an operation of discharging the gas in the stoma device 100 at an appropriate time before the amount of gas accumulated in the storage container 110 exceeds approximately 300 cc. Specifically, by compressing the storage container 110 containing the excrement (typically by hand), the gas stored in the storage container 110 passes through the deodorizing member 10 and the stoma device 100. To the outside. Since the deodorizing member 10 according to the present embodiment has good gas flowability as described above, the forced exhaust of gas can be performed easily and quickly. Moreover, since the deodorizing member 10 uses the unsupported deodorizing particles 14a, the deodorizing efficiency is good. For this reason, even if it performs such forced exhaustion, the outstanding deodorizing performance can be exhibited. Since the deodorizing member 10 is installed so that the gas appliance side end surface is substantially perpendicular to the wall surface 110A in a posture lying sideways on the inner side of the upper end of the stoma device 100, the content moves along the wall surface 110A. Therefore, it is difficult for the gas inlet side end face to be covered.

Although it does not specifically limit, in the deodorizing member 10 arrange | positioned along the wall surface 110A of the stoma appliance 100 in this way, the short diameter in the cross section orthogonal to the gas flow path 13 of the deodorizing container 12 is a deodorizing member. From the viewpoint of suppressing 10 from greatly protruding from the body, it is suitably about 50 mm or less, preferably 25 mm or less, more preferably 20 mm or less, and even more preferably 15 mm or less. Further, from the viewpoint of gas discharge efficiency, it is appropriate that the minor axis is usually 5 mm or more.
In addition, since the deodorizing container 12 of this embodiment is a cylindrical type, the shape of the outer periphery in the cross section (henceforth "vertical cross section") orthogonal to the gas flow path 13 of this deodorizing container 12 is circular, and this circle | round | yen The diameter (cylinder outer diameter) and the short diameter of the deodorizing container coincide with each other. For the deodorizing container whose outer peripheral shape in the vertical cross section of the deodorizing container is different from the circle, draw the rectangle with the smallest area that circumscribes the outer periphery, and the length of the long side of this rectangle is the long axis and the short side And the length of the minor axis is designed to be approximately 50 mm or less (preferably 25 mm or less, more preferably 20 mm or less, still more preferably 15 mm or less).

  Although it does not specifically limit, the internal diameter in the vertical cross section of the deodorizing member 10 can be about 45 mm or less (preferably 23 mm or less, More preferably, 18 mm or less, for example, 13 mm or less). Moreover, the said internal diameter can be about 3 mm or more (for example, 5 mm or more). When the inner peripheral shape in the vertical cross section of the deodorizing container is a shape different from the circle, the minor axis of the inner peripheral shape may be in the above range. Moreover, the length (axial length) of the deodorizing container 12 which comprises the deodorizing member 10 can be about 4 mm-100 mm, for example, Usually, about 10 mm-80 mm (typically about 15 mm-60 mm, for example, It is appropriate to be about 35 mm to 50 mm.

  Although not particularly limited, the length of the deodorant particle filling portion 14 can be, for example, about 3 mm to 95 mm, and is usually about 8 mm to 75 mm (typically about 13 mm to 57 mm, for example, 20 mm to 48 mm. Is appropriate). Further, the amount of deodorant particles 14a constituting the deodorant particle filling unit 14 (filling amount into the gas flow path 13) can be, for example, about 0.25 g to 1.25 g, and 0.3 g to 1.g. It is preferably about 0 g.

  FIG. 3 is a schematic perspective view showing a deodorizing member 20 according to a modification of the first embodiment. In the deodorizing member 20, the outer peripheral portion of the breathable pressure-sensitive adhesive sheet 17 a that covers the other end 12 </ b> B of the deodorizing container 12 is attached to the outer periphery of the deodorizing container 12. One end 12 </ b> A of the deodorizing container 12 is covered with a breathable adhesive sheet 16. The deodorizing member 20 includes a breathable cover 28 attached to the further upstream side of the breathable pressure-sensitive adhesive sheet 16. Since the other points are basically the same as those of the deodorizing member 10, overlapping description is omitted.

  As a constituent material of the breathable cover 28, the porous resin film as described above can be preferably adopted. For example, the breathable cover 28 of the present embodiment is a porous resin film (Nitto Denko Corporation) having a structure in which a polyester and polyethylene nonwoven fabric are laminated on one side of a PTFE porous film having an oil repellency of 12 or more. Product name “TEMISH”). More specifically, one porous resin film is folded in two so that the polyester and polyethylene nonwoven fabric side is on the inside, and the two sides of the two-fold shape are heat-welded to heat-seal portion 28a, By forming 28b, the breathable cover 28 is obtained. The inlet side end of the deodorizing member 20 is inserted through the opening of the breathable cover 28, and the inner surface of the breathable cover 28 is fixed to the outer periphery of the deodorizing container 12 by a technique such as heat welding.

  According to the deodorant member 20 configured as described above, the breathable cover 28 having excellent water and oil repellency is disposed at the inlet side end of the deodorant member 20, so that the content of the container 110 can be reduced. A situation in which the inflow of gas to the deodorizing member 20 is prevented by the adhesion can be better prevented. The breathable cover 28 is gently inclined from the portion where the one end 12A of the deodorizing container 12 is inserted to the heat seal portions 28a, 28b with the fold in the half-fold shape as the upper end. The above-mentioned contents that have come into contact are easily slipped off. As a result, the effect of favorably maintaining the inflow of gas to the deodorizing member 20 can be more effectively exhibited.

Second Embodiment
FIG. 4 is a schematic perspective view showing a container (stoma orthosis) with a deodorizing member according to another embodiment configured using the deodorizing member 10 described above. FIG. 5 is a schematic perspective view showing the main part, and FIG. 6 is a sectional view taken along the line VI-VI.

  In the stoma orthosis 200 according to this embodiment, the deodorizing member 10 is installed on the outer surface of the storage container 110. Specifically, a through-hole 210B for venting gas is formed in the vicinity of the upper end of the outer film, and the porous resin film 230 (preferably an oil-repellent PTFE porous film having an oil repellency of 12 or more is covered with the through-hole 210B. ) Is installed. As shown in FIG. 5, the deodorizing member 10 is accommodated in an airtight pack 232 formed by thermally welding the outer periphery of two airtight sheets, and a flange portion 238 formed on the outer periphery of the airtight pack 232. Is fixed to the storage container 110 by bonding to the outer surface of the outer film by heat welding or the like. The deodorizing target gas pushed out from the through-hole 210 </ b> B through the porous resin film 230 is introduced into the airtight pack 232, is deodorized by passing through the gas flow path 13 in the deodorizing member 10, and the airtight pack 232. It is discharged to the outside through a slit 232A provided at the downstream end of. Here, a non-breathable foam 236 is filled between the outer periphery of the deodorizing member 10 and the inner surface of the airtight pack 232 as shown in FIG. As a result, the upstream side and the downstream side of the deodorizing member 10 are hermetically separated in the airtight pack 232, and the deodorizing target gas reaches the slit 232 </ b> A without passing through the gas flow path 13 in the deodorizing member 10. Is preventing. Since the other points are basically the same as those of the stoma device 100 of the first embodiment, a duplicate description is omitted.

  In the first and second embodiments described above, the deodorizing members 10 and 20 including the deodorizing container 12 having a cylindrical shape (that is, the outer peripheral shape in the vertical cross section is circular) have been described. The shape of the container is not limited to this. The outer peripheral shape in the vertical cross section of the deodorizing container may be, for example, an ellipse, an oval, a semicircle, a jelly beans, a rectangle, a square, a trapezoid, or the like. In a deodorizing member that is assumed to be used directly or indirectly such as a deodorizing member for a stoma appliance, a deodorizing container having a shape with no corners in the outer peripheral shape in the vertical section is preferable.

  The gas flow path of the deodorizing member disclosed herein has an aspect ratio of 5 or less (more preferably 2 or less, more preferably 1.5 or less) in the shape in the vertical cross section (the inner peripheral shape in the vertical cross section of the deodorizing container). Or less). That is, it is preferable that the major axis in the vertical cross-sectional shape of the gas channel is not more than five times the minor axis. By adopting such a gas flow path, unsupported deodorant particles can be appropriately filled in the gas flow path. The major axis and the minor axis in the vertical cross-sectional shape of the gas flow path draw a rectangle with the smallest area circumscribing the outer periphery of the vertical cross-sectional shape, and the long side of the rectangle has a major axis and the short side has a minor axis. It can be calculated as a diameter. In a gas flow path having a circular shape in the vertical cross section, the aspect ratio in the vertical cross section of the gas flow path is 1. The lower limit of the aspect ratio is 1 from the definition.

In one embodiment, the gas flow path of the deodorant member is preferably open area in the vertical cross section is 500 mm ² or less, 250 mm ² or less (e.g., 150 mm ² or less, further 100 mm ² or less) and more to be preferable. By setting the opening area of the gas flow path to be equal to or smaller than the above value, it becomes easy to maintain the state in which the unsupported deodorized particles are appropriately filled in the gas flow path in the deodorizing member filling portion, and the deodorizing effect There is a tendency for certainty to increase. The lower limit of the opening area of the gas flow path is not particularly limited, but usually 15 mm ² or more is appropriate and 25 mm ² or more is preferable from the viewpoint of deodorizing ability.

  The length of the deodorant particle filling part is preferably 1.5 times or more the circle-converted diameter based on the opening area of the gas flow path. For example, in the usage mode in which the container is compressed as described above and the deodorant target gas in the container is forcibly exhausted, because the gas velocity in the gas flow path is high, the deodorant target gas and the deodorant particles There is a tendency that the contact area and the contact time are not sufficient. By setting the length of the deodorant particle filling part to 1.5 times or more (more preferably 2.0 times or more, more preferably 3.0 times or more, for example, 5.0 times or more) of the above-mentioned circle conversion diameter, The deodorizing target gas passing through the gas flow path can be sufficiently brought into contact with the deodorizing particles, and a high deodorizing effect can be exhibited.

As a result, the gas pushed out from the opening 64A of the inner bag 64 (gas containing odor derived from the odor generating source 62) is deodorized by passing through the gas flow path 13 of the deodorizing member 10, and from the through hole 310B. It is discharged outside. Subsequently, the opening 64A of the inner bag 64 containing the odor generating source 62 is closed while the fastener 312 is closed. The opening 64A can be closed by known means such as bending, adhesion, and fastener. Thereafter, the fastener 312 is opened, and the inner bag 64 in a compressed state with the odor generating source 62 is taken out from the storage container 310. Thus, the odor generating source 62 can be compressed in the inner bag 64 while deodorizing the gas pushed out from the odor generating source 62.

The deodorizing unit 420 includes a deodorizing member 10, a deodorizing member installation portion 424 that is a tubular member having one end opened and is used by installing the deodorizing member 10, and gas pushed out from the deaeration bag 66. And a connecting pipe 422 leading to the deodorizing member installation portion 424. The deodorizing unit 420 is configured so that the deodorizing member 10 installed in the deodorizing member installation unit 424 can be replaced.
For example, as shown in FIG. 9, the deaeration and deodorization apparatus 400 may include a stock unit 406 that stocks unused deaeration bags 66 below the compression table 402. As the deaeration bag 66, a heat-sealable resin film (for example, a polyethylene resin film) is used.

  The deaeration and deodorization apparatus 400 is used as follows, for example. First, the pressing sheet 404 is lifted and the deaeration bag 66 containing the odor generating source 62 is placed on the compression table 402. At this time, the tip of the connection pipe 422 is inserted from the opening of the deaeration bag 66. Next, the pressure sheet 404 is lowered, and the gas in the deaeration bag 66 is pushed out by compressing the deaeration bag 66 between the pressure sheet 404 and the compression table 402. The extruded gas is introduced into the deodorizing member installation unit 424 through the connecting pipe 422, and is deodorized by passing through the deodorizing member 10 installed in the deodorizing member installation unit 424, and the deodorizing member installation unit It is discharged from the open end of 424.

The fourth embodiment can be preferably applied to, for example, the compression process of the odor generating source 62 similar to the third embodiment.

<Deodorant used>
(Sample A)
A cylindrical tube having an inner diameter of 6 mm, an outer diameter of 6.4 mm, and a length of 30 mm was used as a deodorizing container. After closing one end of the deodorizing container with a breathable pressure-sensitive adhesive sheet, the deodorizing container was held with the other end (open end) facing up. After supplying 0.3 g of powdery deodorizing particles into the deodorizing container from this open end, a deodorizing particle filling part having a length of about 25 mm was formed by applying light vibration to increase the packing density of the particles. . By stuffing the cushion material from above the deodorant particle filling part, and closing the other end of the deodorant container with a breathable adhesive sheet so that the cushion material is slightly compressed in the length direction of the deodorant container, The deodorant particle filling portion is compressed by the elastic repulsion of the cushion material. The air permeability of the deodorant member according to Sample A thus obtained was 34 seconds / 100 cc.

In addition, as the deodorizing particles, functional activated carbon particles formed into granules of 30 mesh pass and 140 mesh on and containing substantially no particles having a particle size of 100 μm or less and particles having a particle size of more than 500 μm were used. The activated carbon particles had an average particle size of about 250 μm.
As the breathable pressure-sensitive adhesive sheet for closing one end and the other end of the deodorizing container, a product name “Nitoru AP-0300” (manufactured by Nitto Lifetech Co., Ltd.) (porous polyolefin base material and SIS hot-melt pressure-sensitive adhesive layer) And a Gurley type air permeability of 1 second / 100 cc).
As the cushion material, a breathable sponge sheet having a thickness of 5 mm (trade name “40CR-50” manufactured by Kurabo Industries Co., Ltd.) cut into a circle having a diameter approximately 20% larger than the inner diameter of the deodorizing container is used. used.

(Sample B)
Similar to the preparation of the deodorizing member according to Sample A except that a cylindrical tube having an inner diameter of 8 mm, an outer diameter of 8.5 mm, and a length of 30 mm was used as the deodorizing container and the deodorizing particle filling amount was changed to 0.5 g. Thus, a deodorizing member according to Sample B was produced. The air permeability of the deodorant member according to Sample B was 21 seconds / 100 cc.
In addition, when “Nitoru AP-0300” used in Sample B was changed to a water- and oil-repellent PTFE membrane “TEMISH NTF2032A-1006” manufactured by Nitto Denko Corporation, the air permeability was 38 seconds / 100 cc.

(Sample C)
Similar to the preparation of the deodorizing member according to Sample A, except that a cylindrical tube having an inner diameter of 10 mm, an outer diameter of 10.5 mm, and a length of 30 mm was used as the deodorizing container and the deodorizing particle filling amount was changed to 0.78 g. Thus, a deodorizing member according to Sample C was produced. The air permeability of the deodorizing member according to Sample C was 10 seconds / 100 cc.

(Sample D)
A deodorizing member equipped with a commercially available stoma device (a deodorizing container having an inner dimension of 20 mm long side, 10 mm short side, and about 4 mm thickness is accommodated with a cloth carrying activated carbon, and the thickness of the deodorizing container A deodorizing filter configured to allow odor gas to flow in the direction was used. The air permeability of this deodorizing member was 50 seconds / 100 cc.

<Evaluation of deodorant effect durability by forced exhaust>
About the deodorizing member which concerns on each sample, the deodorant lasting effect was evaluated on condition of the following.
That is, a plurality of original odor bags were prepared in which 40 g of feces was placed in a sealed container having a capacity of about 30 liters and stored at 40 ° C. for 3 hours. When the main odor contained in this original odor was measured with a detector tube, it was 4 ppm of hydrogen sulfide, 4 ppm of ammonia, and 4 ppm of amines. From this original odor bag, 300 cc of odor gas was extracted with a syringe and sent to the inlet side of the deodorant member (the side opposite to the side where the cushioning material was disposed) at a supply rate of about 50 cc / sec. The gas that permeated the deodorizing member was collected in a sealed container having a capacity of 3 liters, and one odor panelist sensory evaluated the odor of the collected gas.
This test was repeated for every 300 cc of odor gas, and the gas odor level after permeation and the number of times of supply were recorded. For example, the number of times in the level 2 column for the deodorant member of sample A in Example 1 is “45”, and 300 cc of odorous gas is 45 times from the start of the test until it is determined to be level 3 (13.5 liters in total). ) Deodorization is possible. The criteria for each level of sensory odor are as follows.
1: Odorless 2: Smell slightly 3: Smell at close range (not aware of stool odor by outsiders)
4: Obvious smell (perceived by the outside outsiders as fecal odor)
5: No deodorizing effect (the same as the original odor)

  The obtained results are shown in Table 1 together with the schematic configuration of each deodorizing member.

  From the results shown in Table 1, the deodorizing members of Samples A to C using non-supported activated carbon particles have a deodorizing effect on forced exhaust compared with the deodorizing member of Sample D in which the activated carbon particles are supported on a cloth. It can be seen that the sustainability is extremely high. For sample A according to Example 1, deodorization was possible as many as 150 times until the odor level 3, whereas the total number of deodorizations at odor level 4 and level 5 was 10 times. The deodorizing effect decreased rapidly after 150 times. This is due to the fact that hydrogen sulfide in the stool smells strongly at the sensory level when the deodorizing particles are adsorbed below a certain level.

In addition, as a deodorizing container, a regular rectangular tube type polyethylene frame having an inner size of 15 mm square, an outer size of 17 mm, and a length of 4 mm was used, and this was filled with 0.36 g of the same deodorizing particles as in Example 1, Sample E (gas channel cross-sectional area 225 mm ² , deodorant particle filling portion volume 900 mm ³ , gas channel aspect ratio 1.0, air permeability 1.5 seconds) / 100cc), the deodorant efficacy sustainability was evaluated at a supply rate of about 50 cc / second in the same manner as above, and it was confirmed that the deodorant efficacy persistence was significantly improved compared to Sample D (Comparative Example). However, the sustainability of Examples 1-3 was not obtained. When the gas supply rate to this sample E was changed to about 20 cc / second, the deodorant effect sustainability was clearly improved as compared with the case where the gas supply rate was evaluated at about 50 cc / second. The level was lower than 3. These results show that the odor gas stays in contact with the surface of the deodorant particles when the gas supply rate is high, for example, when the gas accumulated in the stoma is pressed and forced exhausted. This suggests that the adsorption rate of the deodorant particles cannot catch up, and as a result, the deodorant effect is hardly produced. As in samples A, B, and C, by increasing the gas flow path length by 1.5 times or more of the opening area, the contact time between the odor gas and the deodorant particles is increased, and the deodorizing effect is maintained. Can be increased.

  The present invention is not limited to the above-described embodiments, and various modifications and changes can be made within the scope of the claims. Further, embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the technical scope of the present invention.
