Description

  The present invention relates to a medical pouch, and more particularly to a medical pouch that is used by being attached to the body surface in order to collect a large amount of excrement and exudate discharged from a fistula such as an artificial anus or a small intestinal fistula.

  A colostomy is constructed in the case of surgery to remove the intestine and excretes feces. Gastrointestinal stoma is produced in the colon of the large intestine (colon stoma), ileostomy in the ileum of the small intestine (ileal stoma), and rarely in the jejunum.

  The feces excreted when an artificial anus is constructed in the ileum or jejunum of the small intestine is a state where water is not absorbed in the large intestine, and almost all of the water ingested in the body is mixed in the digestive residue of food. It is discharged as so-called watery stool and is excreted in a large amount in a short time. For this reason, when a normal medical pouch is used, the bag body for storing the excrement becomes full in a short time, and accordingly, work for discharging the excrement from the bag body is frequently required.

  In the product name “Ilefine”, Arca, Inc., the discharge part of the bag body has a tubular shape that easily discharges watery stool, and even if sludge is mixed in the excrement, it can be squeezed (milking) The tube is connected at night so that it can be continuously discharged to an external container. In Coloplast, the product name “Ashley Leo Pouch”, the capacity of the bag body is doubled from the usual so that the interval between discharge operations is longer. The company's product name “Ashura Knight Drainage” can be used for patient care after the operation by extending the part from the attachment part to the storage part, and performing the draining operation away from the patient's body. In this way, the burden on the patient is reduced.

  A state where the epithelial surface of an organ or organ and the epithelial surface of another organ are in communication is called a fistula, and a tubular hole formed between the small intestine and the body surface is called a small intestinal fistula. In small intestinal fistula, large amounts of internal secretions such as small intestinal fluid, pancreatic juice, bile, and exudates from the fistula must be discharged, and the wound must be managed while processing these discharged fluids. In the fistula where the digestive tract, urinary tract, and body surface are in communication, a large amount of exudate is generated. A bag attached to the body surface around the fistula is used to collect the effluent from the fistula. For example, the product names “Well Care Drain” and “Surge Drain Open Top” by the applicant are sold. ing. Patent Documents 1, 2, and 3 relate to the collection bag. In such a bag, the discharged liquid is once collected, a tube is connected to a discharge tubular connector provided at one end of the bag, and the collected discharged liquid is discharged to a container provided outside.

  However, in the above prior art, when the size is increased in order to increase the capacity of the bag body, it is difficult for the user to avoid a sense of incongruity, and it becomes difficult to maintain a normal living level. If the discharge port is connected to an external container using a tube to further increase the substantial capacity, the discharge port may be clogged with solid components in the excrement. The user cannot take a good night's sleep because an operation to swallow the minute is required. If the diameter of the tube is increased, a sense of incongruity for the user cannot be avoided.

  In a collection bag attached to a small intestinal fistula etc., although rare, when a patient ingests food, food that cannot be digested by a large amount of exudate is mixed as a solid component, so the tube connected to the bag is clogged. There is a fear. This requires extra care.

  Then, this invention solves the problem of the said prior art, and makes it a subject to provide the medical pouch which can collect | recover the large amount of discharge | emission excreted from the artificial anus and the fistula stably over a long time.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a large amount of discharge | emission containing a solid component with a liquid component, there is no clogging of a discharge route and the medical pouch which can be collect | recovered stably over a long time can be provided. In addition, the medical pouch according to the present invention can be manufactured at low cost because it is possible to separate the liquid component and the solid component from the excrement only by adding a simple member to the conventional medical pouch. be able to.

Embodiments relating to the main requirements of the medical pouch of the present invention will be described below. The specific configuration of the medical pouch will be described in the section of an example described later.
The filter means of the present invention only needs to be able to effectively separate the solid component from the excrement when the excrement flows down inside the bag, and the solid component that clogs the discharge port is substantially separated. Just do it. The solid component in watery stool is not difficult to separate from water like the solid component of mud stool or soft stool, and since it has a relatively large particle size and shape, it passes through the filter means Easily separated from liquid components.

  The filter means is preferably a porous sheet member. The porous sheet-like member is a thin sheet-like member provided with many small-diameter through holes. For example, a mesh sheet having a substantially square through-hole made by extrusion molding from low density polyethylene, high density polyethylene, polypropylene, EVA, etc. to a thickness of several tens to several hundreds μm, and a net knitted from plastic yarn In addition, a mesh sheet having substantially square through holes, a multi-perforated sheet in which circular through holes are formed on a continuous sheet by post-processing of punching, and the like can be used. Moreover, the nonwoven fabric sheet which consists of polyethylene etc. can also be used. The material of the porous sheet-like member may be paper other than plastic. Moreover, it is preferable that the porous sheet-like member is flexible and can be fixed to the bag body using an adhesive so as to be suitably incorporated in the bag body.

  The through hole through which the liquid component of the filter means passes is 0.04 mm to 5 mm, preferably 0.1 to 4 mm, more preferably 0.5 to 3 mm in terms of the equivalent diameter. If it is 0.04 mm or less, clogging occurs in a short time, so that it cannot withstand long-term use, which is the original purpose. If it is 5 mm or more, most of the solid components pass through, so that it is difficult to obtain a substantial effect by separation.

  The area of the filter means is not particularly limited as long as it can be used without clogging, for example, at the time of nighttime sleep time, depending on the application. In addition, the filter means may stack two or more porous sheets in order from the one having the larger pore size.

  When the bag body is made of a thermoplastic resin film and the porous sheet-like member is made of a thermoplastic resin, the bag body and the filter member are integrally melted and assembled by a sealing means such as heat seal. Can do. When the two films constituting the bag were joined to each other with the porous sheet-like member sandwiched between them, the thermoplastic resin melted at the joined part to fill the gap and sealed without leakage. A bag can be constituted.

  As a thermoplastic resin film which comprises a bag body, it consists of a plastic film which has water resistance and gas barrier property, is flexible, and has sealing properties, and what is conventionally used for an ostomy pouch can be used. For example, polyvinylidene chloride, polyethylene, polyvinyl chloride, chlorinated polyethylene, or a single layer or laminated film obtained by blending or copolymerizing vinyl acetate, polyacrylic acid, or the like.

  The plurality of discharge means of the present invention may be any means as long as the liquid component and the solid component separated by the filter means are discharged separately. The liquid component discharge port is preferably tubular, and preferably has a cap that can be easily connected to a container such as a bag provided outside, to which a cap that can be freely opened and closed is attached. In the case of a tubular shape, it is preferably made of a flexible material so that it can squeeze out when mixed sludge is accumulated. The solid component outlet can be opened without sealing one end of the bag, and can be opened and closed by a known closing means such as a hook-and-loop fastener attached to the surface of a clip or pouch.

  The position where the filter means is disposed inside the bag body is not particularly limited as long as it is a route for excrement, but in normal use, the filter means may be disposed on the downstream side where the excrement falls from the colostomy. That's fine. Accordingly, the discharge port for discharging at least the liquid component from which the solid component has been separated is disposed at the lower part of the bag body further downstream of the filter means, and in this case, the bag body together with the discharge port for discharging the separated solid component. Can be arranged side by side.

Next, based on FIG. 1 and FIG. 2, the Example of the ostomy pouch of this invention is described below.
Example 1
FIG. 1 is a schematic configuration diagram of Example 1 according to the ostomy pouch of the present invention, FIG. 1 (a) is a front view seen from the direction of attachment to the body, and FIG. 1 (b) is a diagram of FIG. 1 (a). It is a sectional side view along the AA line. For convenience of explanation, the dimension in the horizontal direction of each member in FIG. 1B is shown in a dimensional ratio that is considerably different from the actual one.

  In FIG. 1, 1 is a face plate, 2 is an opening, 3 is an adhesive layer, 4 is a laminate layer, 5 is a comfort layer, 6 is a bag, 7 is a front film, 8 is a rear film, 9 is an intermediate member, and 9a is Mesh sheet, 9b is an intermediate film member, 11 is a discharge port for liquid components, 12 is a discharge port for solid components, 13 is a polyethylene film for check valve, 14a and 14b are spot welds, 15 is an outer periphery, 16 is The front chamber 17 is a rear chamber. Details of the configuration and function of each member will be described below.

  The face plate 1 has an opening 2 for receiving an artificial anus at the center, and an adhesive layer 3, a laminate layer 4, and a comfort layer 5 made of a non-woven material are laminated in order from the side to be worn on the human body. The comfort layer 5 is substantially the same size as the bag body 6, and the peripheral edge exposed to the opening 2 is sealed so that excrement does not penetrate, and extends to the lower side of the bag body 6. The face plate 1 and the bag 6 are preferably detachable by coupling means such as fitting or adhesion, but in this embodiment, description of the coupling means and the like is omitted.

  The bag body 6 includes a front film 7 and a rear film 8, and the inside of the bag body is divided into two by a middle member 9 into a front chamber 16 that contacts the front film 7 and a rear chamber 17 that contacts the rear film 8. ing. Furthermore, it has the structure which provided the discharge port 12 for solid-component discharge | emission and the discharge port 11 for liquid component discharge | emission in the bag body lower part of the front chamber 16 and the back chamber 17, respectively.

  The front film 7 and the rear film 8 are made of, for example, a laminate film in which a polyvinylidene chloride film is sandwiched between polyethylene films manufactured using a metallocene catalyst. Although the intermediate member 9 is omitted in the drawing, the mesh sheet 9a and the intermediate film member 9b, which are porous sheet members, are formed by joining adjacent end portions to each other. The intermediate film member 9b is made of a polyethylene film. The mesh sheet 9a used as a filter is a product name “Starnet” manufactured by Takiron Co., which has a thickness of 0.25 mm extruded from polyethylene as a main material and a mesh density of 21 / inch. Although not shown in the figure, the liquid component outlet 11 is provided with a so-called bowl-shaped connector whose outer periphery is reduced in a stepped manner so that an elastic tube for discharging it into a container provided outside can be fitted. In addition, a removable cap can be attached.

  The lower portion of the bag body 6 forming the solid component discharge port 12 is not shown, but when the solid component is not discharged, the end portion is rolled up and fixed by a closing means such as a hook-and-loop fastener or a clip and discharged. When this is done, the closing means is released and the end portion is opened to allow the discharge. Further, when the connector of the discharge port 11 of the hard liquid component compared to the bag 6 is in contact with the skin, it may irritate the skin and cause inflammation, so it is not clear in FIG. It is preferable that the length of the terminal portion is such a length that the connector of the discharge port 11 does not come into contact with the skin in the rolled-up state.

  A check valve can be provided at the lower part of the rear chamber 17 in order to prevent the back flow of the liquid component. The check valve is formed by joining the upper end of the check valve polyethylene film 13 to the inner surface of the rear film 8 and spot welding the intermediate film member 9b at two locations 14a and 14b below. 13 and a gap formed between the intermediate film member 9b. Note that the mesh sheet 9 a may be extended as close as possible to the discharge port 11 without providing the check valve polyethylene film 13.

  Each part of the bag is assembled as follows. The outer peripheral portion 15 of the front film 7 and the rear film 8 is heat-sealed with the mesh sheet 9a sandwiched in the upper portion, and the portion following the heat-sealed portion sandwiching the mesh sheet is heat-sealed sandwiching the intermediate film member 9b. The lower part of the rear film 8 is in close contact with the central part wound around the outer periphery of the liquid component discharge port 11, and both sides are joined to the intermediate film member 9b. The lower side of the front film 7 is joined to the intermediate film member 9b on both sides of the outer peripheral portion. For this reason, the inside of the bag body 6 is divided into a front chamber 16 and a rear chamber 17 with an intermediate member 9 formed by the mesh sheet 9a and the intermediate film member 9b as a boundary. The bag body 6 can be provided with a comfort layer on the outer side of the rear film 8 or can be provided with a conventionally known member such as a deodorizing filter.

  Next, the effect | action which isolate | separates a solid component from excrement is demonstrated. Here, in accordance with normal usage, the user patient is lying sideways on the bed, and the ostomy pouch of the present invention is perpendicular to the body, i.e., the outlets 11 and 12 are below the opening 2. It is attached so that it may be located in. A tube is attached to the liquid component discharge port 11 so as to communicate with a container provided outside, and the solid component discharge port 12 is rolled up and sealed with a hook-and-loop fastener or a clip.

  When the watery stool discharged from the colostomy is discharged to the front chamber 16 of the bag body, it hits the mesh sheet 9a, the liquid component permeates the rear chamber 17 (arrow 18), and the solid component is below the front chamber 16. (Arrow 19). The watery stool discharged to the front chamber 16 and not reaching the mesh sheet 9a falls as it is below the front chamber 16. For this reason, watery stool accumulates in the lower part of the front chamber 16 in a state where the solid component is sunk. The liquid component that has entered the rear chamber 17 passes through a gap having a check valve action constituted by the intermediate film member 9b and the check valve polyethylene film 13, and flows down into the liquid component discharge port 11, Further, it is discharged to a container provided outside through a tube connected to the discharge port 11.

  When the discharge of the watery stool continues, the liquid level of the watery stool collected in the front chamber 16 reaches the upper end of the intermediate film member 9b, and the liquid component present at the upper part of the accumulated watery stool is transferred to the intermediate film member 9b. When the upper end is exceeded, it is separated by the mesh sheet 9 a and overflows into the rear chamber 17. Thus, the solid component in the watery stool is stored in the front chamber 16, and the liquid component is separated by the mesh sheet 9a, enters the rear chamber 17, and is discharged to the outside. For this reason, a large amount of watery stool is not stored in the bag as it is, and since the solid component is separated by the mesh sheet 9a, the tube is not clogged. When the front chamber 16 is filled with the accumulated solid component, the solid component discharge port 12 is opened and discharged.

(Example 2)
Next, Example 2 will be described with reference to FIG. 2 is a schematic configuration diagram of Example 2 according to the ostomy pouch of the present invention, FIG. 2 (a) is a front view seen from the direction of attachment to the body, and FIG. 2 (b) is a diagram of FIG. 2 (a). It is a sectional side view along the BB line. 2 is different from the first embodiment in that the filter means is arranged below the bag body, members having the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. To do.

  The filter means 20 in the present embodiment is made of a polyethylene sheet having a thickness of 30 μm having a through hole region 20a in which through holes having a diameter of 2 mm are formed at a pitch of 8 mm in length and width and a continuous region 20b having no through holes. The filter means 20 is joined to the inner surface of the front film 7 at the upper end portion 20c in the through hole area 20a, and is joined to the rear film 8 in the continuous area 20b and is liquid-tightly joined together with the front film 7 across the connector of the discharge port 11. ing. For this reason, the inside of the bag body 6 is divided at the lower part on the body side with the through hole region 20a of the filter means 20 as a boundary. Here, the upstream side of the through-hole region 20a is referred to as the upper chamber 21, and the downstream side into which the liquid component from which the solid component has been separated by the through-hole region 20a flows is referred to as the lower chamber 22. In the present embodiment, the lower chamber 22 exists only in a part of the lower portion of the bag body 6, and the upper chamber 21 occupies most of the volume of the bag body 6, so that the solid component can be efficiently accommodated in the bag body 6.

  In the present embodiment, the excreta is separated as follows. When the watery stool discharged from the colostomy is discharged into the upper chamber 21 of the bag body, it strikes the through hole region 20a of the filter means 20 to separate the solid component and the liquid component permeates into the lower chamber 22 (arrow 23). ). The separated solid component falls below the upper chamber 21 (lower right corner in the drawing) and accumulates (arrow 24). For this reason, in the lower part of the upper chamber 21, the watery stool accumulates in a state where the solid component is sunk. The liquid component that has entered the lower chamber 22 flows down into the connector of the discharge port 11 and is discharged to a container provided outside via a tube connected to the connector of the discharge port 11. The liquid component of the watery stool collected in the upper chamber 21 starts to flow into the lower chamber 22 when it exceeds the upper edge 20d of the continuous region 20b. When the upper chamber 21 is filled with the separated solid component, the accumulated solid component is discharged by opening the discharge port 12.

  Various other modifications are possible. All of the above examples are used as an ostomy pouch corresponding to an artificial anus. For example, when the example 2 corresponds to a fistula or a wound, it is opposed to a fistula or a wound on the rear film 8 of the bag. The site to be opened may be opened and closed so that the wound can be observed and treated.

  Further, when discharging the solid component, a cleaning opening may be separately provided so that excrement adhered to the inner surface of the bag body 6 and the filter means can be cleaned at the same time. The bag body 6 can be opened and closed by providing a fastener without sealing the upper end, or by appropriately using a closing means such as a clip without providing a fastener. In this case, the upper end is closed during normal use, and when the inside needs to be cleaned, the closure is released and cleaning water is introduced from above. In the case of Example 2, a cleaning water inlet with a cap may be provided on the upper portion of the rear film 8.
