  FIG. 1 is a plan view showing a state before use of an ophthalmic drape 1 (hereinafter simply referred to as “drape 1”) according to a first embodiment of the present invention. The drape 1 is a sterilized sheet-like member, and is a patient in an unclean area by covering the face of a patient undergoing medical treatment such as surgery in a medical facility such as an operating room or a treatment room. Isolate clean areas from the body surface. The left-right direction in FIG. 1 corresponds to the left-right direction of the patient's face, and the up-down direction in FIG. 1 corresponds to the up-down direction perpendicular to the left-right direction of the patient's face (that is, the direction in which the nose extends).

  As shown in FIG. 1, the drape 1 includes a substantially rectangular seat portion 2 in which an opening 20 corresponding to one eye of a patient is formed, and a main surface 21 on the opposite side of the seat portion 2 from the patient side (i.e., , A clean surface facing the clean area, and hereinafter referred to as “surface 21”), is provided with a shape-retaining member 3, a deployment grip 4, and a medical pouch 5. The medical pouch 5 is a so-called water receiving bag that receives liquid (for example, blood, body fluid, physiological saline used for cleaning the surgical field) from the surgical field at the time of surgery, and the liquid receiving port 51 is draped. It is fixed with double-sided adhesive tape or the like in the vicinity of the opening 20 so as to face one opening 20.

  An adhesive layer 23 is formed around the opening 20 on the main surface 22 of the seat portion 2 facing the patient (that is, the unclean surface facing the unclean region, hereinafter referred to as “back surface 22”). When the drape 1 covers the patient's face, the sheet portion 2 is disposed so that the opening 20 overlaps one eye where medical treatment is performed, and the eye is exposed from the sheet portion 2. And the adhesion layer 23 is affixed on the skin around eyes. Thereby, in the state where the patient's face is covered with the drape 1, it is possible to easily access the eye as the treatment target site through the opening 20.

  The sheet portion 2 is preferably formed of a nonwoven fabric or a plastic film. In the present embodiment, since the sheet portion 2 is formed of a plastic film, it does not substantially have air permeability. By configuring the sheet portion 2 in such a structure, blood or the like attached to the surface 21 of the sheet portion 2 passes through the sheet portion 2 when a force is applied from above the sheet portion 2, and the blood or the like. It is possible to prevent the front surface 21 and the back surface 22 of the sheet portion 2 from communicating with each other (that is, a passage due to the blood or the like is formed between the clean region and the dirty region). The thickness of the sheet part 2 is preferably 200 μm to 500 μm. By making the thickness of the sheet part 2 200 μm or more, the strength of the drape 1 can be sufficiently secured, and by making the thickness of the sheet part 2 500 μm or less, the texture of the drape 1 can be softened. it can.

  FIG. 2 is a view showing a part of a cross section obtained by cutting the drape 1 at the position AA in FIG. As shown in FIGS. 1 and 2, the sheet portion 2 has two folding portions 24 positioned on the upper side and the lower side of the opening 20 in FIG. 1. Each folding part 24 is folded at two folding lines 241a and 241b extending in the left-right direction at a position corresponding to the patient's nose or mouth. In each folding part 24, in a state where the folding part 24 is unfolded, the folding line 241a is closer to the opening 20 than the folding line 241b. In the following description, the fold lines 241a and 241b are referred to as “first fold line 241a” and “second fold line 241b”, respectively.

  In the seat portion 2, the portions on both sides of the first fold line 241 a (that is, two portions where the first fold line 241 a serves as a boundary) are folded back so that the back surface 22 faces each other, and on both sides of the second fold line 241 b. The part is folded so that the surface 21 faces. Thereby, the folding part 24 is formed. In other words, the folding part 24 is formed such that the sheet part 2 is folded on the back surface 22 side.

  As shown in FIG. 2, between the first fold line 241a and the second fold line 241b of each fold part 24, the sheet part 2 overlaps three layers, and the three layers (that is, the first fold line 241a). 1 and the second fold line 241b are joined to each other by double-sided adhesive tape or the like at both ends in the left-right direction of the fold part 24, as shown with parallel diagonal lines in FIG. In the following description, both end portions of the folding portion 24 are referred to as “folding end portions 243”, respectively. The joining at the folded end 243 may be performed by thermocompression bonding, ultrasonic pressure bonding, or adhesion with a hot melt adhesive.

  On the other hand, in the central part in the left-right direction of the folding part 24 (that is, a part continuous to the two folding end parts 243 between the two folding end parts 243, hereinafter referred to as “folding central part 242”). The three superimposed layers of the fold 24 are not joined. The width in the left-right direction of the folding center portion 242 is preferably 30 cm or more and 80 cm or less, and more preferably 40 cm or more and 60 cm or less. In other words, the width in the left-right direction of the folding center part 242 is preferably about 2 to 5 times the face width in the vicinity of the normal adult nose and mouth.

  The shape-retaining member 3 includes two belt-like members 31 that are positioned between the opening 20 and each folding portion 24 in the vertical direction (that is, provided in the upper covering portion 25 described later). Each band-shaped member 31 is disposed at approximately the center in the left-right direction of the sheet portion 2, that is, approximately at the center in the left-right direction of the folding center portion 242. The belt-shaped member 31 is preferably formed of a resin that can be easily plastically deformed (that is, the shape can be easily changed), and is formed of polyethylene or the like in the present embodiment.

  The belt-like member 31 is a linear member extending in the left-right direction, and is joined to the surface 21 of the sheet portion 2 by an adhesive tape or the like over the entire length. The length of the band-shaped member 31 in the left-right direction is smaller than the length of the folding center part 242 in the left-right direction, and both end parts in the left-right direction of the folding center part 242 are located on the outer side in the left-right direction with respect to both ends To do. In a state before the drape 1 is used, the entire sheet portion 2 is folded small (for example, folded up and down and left and right), and the belt-like member 31 is folded in approximately the center. In addition, the sheet | seat part 2 may be folded small, without making the linear and flat strip | belt-shaped member 31 deform | transform.

  Each of the two folding center portions 242 is provided with a strip-shaped developing gripping portion 4 formed of a nonwoven fabric. The unfolding gripping portion 4 extends in the vertical direction at approximately the center in the left-right direction of the folding central portion 242. As shown in FIG. 1 and FIG. 2, the unfolding gripping portion 4 is disposed between two layers that are sites on both sides of the second fold line 241 b among the three layers of the foldable portion 24, and opens from the foldable portion 24. 20 protrudes on the opposite side. One end of the unfolding grip 4 (that is, the end 41 on the side close to the opening 20) has a surface 21 of the sheet portion 2 near the second fold line 241b, as indicated by a parallel oblique line in FIG. To be joined. In other words, the unfolding gripping portion 4 extends from the second fold line 241b toward the first fold line 241a from between the portions on both sides of the second fold line 241b beyond the first fold line 241a.

  In the following description, the end portion 41 fixed to the sheet portion 2 of the unfolding gripping portion 4 is referred to as “fixed end 41”. Further, the end 42 opposite to the fixed end 41 is referred to as a “free end 42”. As shown in FIG. 2, in the development gripping part 4, the parts other than the fixed end 41 are not joined to the sheet part 2. The fixed end 41 is joined by a hot melt adhesive or the like only in the vicinity of the second fold line 241b on the opposite side of the second fold line 241b from the first fold line 241a. The vicinity of the second fold line 241b means a position closer to the second fold line 241b than the first fold line 241a or a position overlapping the second fold line 241b when the fold part 24 is viewed in plan. In the present embodiment, the edge on the fixed end 41 side of the unfolding gripping portion 4 approximately coincides with the second fold line 241b.

  In the manufacture of the drape 1, the hot melt adhesive is applied to only one surface of the fixed end 41 of the unfolding grip 4. Subsequently, in the folded portion 24 that is folded in advance, the space between the two layers that are the portions on both sides of the second fold line 241b is slightly widened, and the unfolding gripping portion 4 extends from the fixed end 41 side between the two layers. Inserted. When the edge on the fixed end 41 side of the unfolding gripping part 4 approximately coincides with the second fold line 241b, the vicinity of the second fold line 241b of the foldable part 24 is pressed, and the fixed end 41 of the unfolding gripping part 4 is hot melted. It joins to the sheet | seat part 2 with an adhesive agent. In the drape 1, the fixed end 41 of the unfolding gripping portion 4 is joined only to one portion of the second fold line 241b, so that the unfolding gripping portion 4 is attached to the seat portion 2 by a simple method as described above. Can be easily joined.

  FIG. 3 is a plan view showing a state in which the drape 1 is spread on the patient's face 90. In FIG. 3, the drape 1 is arranged so that the opening 20 of the seat portion 2 overlaps the left eye of the patient, and the lower belt-like member 31 in FIG. 3 crosses the nose portion 91 on the nose portion 91 of the patient. Extends in the left-right direction. Also, the lower folding part 24 in FIG. 3 is arranged on the lower nose 911 and the mouth part 93 of the patient. In the drape 1, the lower covering portion 26 that covers the lower portion of the patient's face 90 has a folded portion 24 that is folded in a state before use. A portion 25 that is continuous between the two folding parts 24 between the two folding parts 24 is an upper covering part 25 that covers the upper part of the patient's face 90 and is formed with the opening 20. The band-shaped member 31 of the shape retaining member 3 is fixed to the upper covering portion 25 of the drape 1, and the fixed end 41 of the developing gripping portion 4 is fixed to the folding portion 24 of the lower covering portion 26. In the folding part 24, the center in the left-right direction of the folding center part 242 approximately coincides with a center line perpendicular to the left-right direction of the patient's face 90 (that is, a line passing through the nasal bridge).

  When the drape 1 is used, the free end 42 of the unfolding grip 4 is gripped by a doctor, a nurse, or the like and pulled away from the patient's face 90, thereby folding the central portion 242 of the lower fold 24. Are lifted away from the face 90 and spread (ie, unfolded). Further, the belt-like member 31 below the opening 20 is bent so as to be separated from the face 90 by being picked up by a doctor, a nurse or the like. FIG. 4 is a side view of the drape 1 in use, and FIG. 5 is a view of the vicinity of the patient's nose 91 viewed from the lower side (that is, the mouth 93 side). FIG. 5 shows a cross section of the drape 1 at the position of the band-shaped member 31. As shown in FIG. 4, in the folding part 24, the folding center part 242 is expanded, so that the folding center part 242 is three-dimensionally (that is, in a dome shape) in a direction away from the patient's nose 91 and mouth 93. ) Protruding. Thereby, a space 951 is formed between the patient's face 90 and the sheet portion 2 from the lower nose 911 and the mouth portion 93 to the left and right cheek portions 92.

  The shape of the belt-like member 31 extending in the left-right direction on the patient's nose 91 is maintained in a state where the portions excluding both ends in the left-right direction are separated from the nose 91, and the upper covering portion 25 of the seat portion 2 is maintained. Is separated from the patient's nose 91 and its vicinity. Thereby, as shown in FIG. 4, a space 952 continuous from the space 951 is formed between the upper covering portion 25 and the patient's face 90. In the following description, the spaces 951 and 952 between the sheet portion 2 and the face 90 are collectively referred to as a space 95.

  In the drape 1, when the deployment grip 4 is gripped and pulled, as shown in FIG. 4, the folding center 242 can be easily deployed, and the space 951 can be easily formed in the lower nose 911 of the patient. it can. Thereby, the sheet | seat part 2 leaves | separates, without closely_contact | adhering to a patient's nose lower part 911, the mouth part 93, and the cheek part 92. FIG. In the folding part 24, since the width in the left-right direction of the folding center part 242 is 30 cm or more (more preferably, 40 cm or more), a sufficiently large space 951 can be formed by developing the folding part 24. As a result, the close contact of the seat part 2 with the nose lower part 911, the mouth part 93 and the cheek part 92 is prevented, and the patient can easily breathe through the space 951. Moreover, since the width in the left-right direction of the folding center part 242 is 80 cm or less (more preferably, 60 cm or less), the shape of the developed folding part 24 can be easily maintained, and the space 951 can be easily maintained. .

  Further, in the drape 1, by forming the space 952 continuous with the space 951 on the nose portion 91 by the deformation of the shape retaining member 3, the patient can breathe more easily through the space 95. Since the shape-retaining member 3 can be easily changed in shape and maintained, an appropriate breathing space 95 can be easily formed in accordance with various patient face shapes. Furthermore, since the space 95 can be secured without unnecessarily deforming the shape retaining member 3 by unfolding the folding center portion 242, the deformation work of the shape retaining member 3 when using the drape 1 is simplified. Can do.

  In the drape 1, the shape retaining member 3 includes the belt-like member 31 extending in the left-right direction on the patient's nose 91 when in use, so that the seat 2 can be reliably separated from the patient's nose 91, As a result, the space 95 is more reliably maintained. Further, the belt-shaped member 31 is disposed between the opening 20 of the upper covering portion 25 and the folding portion 24, so that the expansion of the folding center portion 242 is prevented from being inhibited by the belt-shaped member 31.

  Thus, since the drape 1 can prevent the patient's breathing by preventing the sheet portion 2 from closely contacting the lower nasal portion 911, the mouth portion 93, and the cheek portion 92 of the patient, the drape 1 is substantially breathable. It is particularly suitable for a drape having a sheet portion 2 that does not have (at least a portion corresponding to the patient's nose portion 91 and mouth portion 93 does not have air permeability).

  In the drape 1, since the shape retaining member 3 is formed of resin, the drape 1 can be discarded without separating the sheet portion 2 and the shape retaining member 3 mainly formed of a nonwoven fabric or a plastic film. Thereby, the operation | work required for disposal of the drape 1 can be simplified.

  The drape 1 can be used for surgery of the left or right eye of the patient. When the surgery of the right eye of the patient is performed, the drape 1 is in a horizontal plane around the axis perpendicular to the drape 1 from the state shown in FIG. And placed on the patient's face 90 in a state rotated by 180 °. Then, the unfolding gripping portion 4 fixed to the upper folding portion 24 in FIG. 3 is pulled to expand the folding center portion 242 and the belt-like member 31 located on the upper side in FIG. 3 is deformed ( The same applies to the drapes according to the following embodiments.) Thereby, similarly to the above, the folding part 24 is separated from the patient's nose part 91 and the mouth part 93 and protrudes in a dome shape, and the above-described space 95 is easily formed between the patient's face 90 and the seat part 2. It is formed. As a result, the sheet portion 2 is prevented from coming into close contact with the patient's lower nose 911, mouth portion 93 and cheek portion 92, and the patient can easily breathe through the space 95.

  Next, an ophthalmic drape according to the second embodiment of the present invention will be described. FIG. A is a partial cross-sectional view of the drape 1a according to the second embodiment, and corresponds to FIG. FIG. B is shown in FIG. FIG. 7 is an enlarged cross-sectional view showing a part of the drape 1a shown in FIG. A, and FIG. 7 is a plan view showing the developing gripping portion 4a of the drape 1a. FIG. In B, in order to facilitate understanding of the drawing, the development gripping portion 4a is drawn with a thick solid line. In the drape 1a, the shape of the deployment gripping portion 4a is different from the shape of the deployment gripping portion 4 according to the first embodiment. Further, the manner of joining the unfolding gripping portion 4a to the sheet portion 2 is also different from that of the first embodiment. The other structure of the drape 1a is the same as that of the drape 1 shown in FIG. 1, and in the following description, the same code | symbol is attached | subjected to a corresponding structure.

  As shown in FIG. 7, in the deployment gripping portion 4a, a notch 43 extending in the longitudinal direction from the edge on the fixed end 41 side to the free end 42 side is provided, and the fixed end 41 is divided into two divided ends. The In the following description, the left portion of the fixed end 41 in FIG. 7 is referred to as “first fixed end 41a”, and the right portion is referred to as “second fixed end 41b”.

  When the unfolding gripping portion 4a is joined to the sheet portion 2, the hot melt adhesive is applied to one surface of the first fixed end 41a, and the hot melt adhesive is applied to the other surface of the second fixed end 41b. Applied. In FIG. 7, a parallel oblique line is given to the area where the hot melt adhesive is applied. Subsequently, FIG. As shown to A, in the folding part 24 folded beforehand, the expansion | deployment holding | grip part 4a is inserted from the fixed end 41 side between two layers which are the site | parts of the both sides of the 2nd folding line 241b. Then, when the vicinity of the second fold line 241b of the fold portion 24 is pressed, FIG. As shown to B, the 1st fixed end 41a of the holding | grip part 4a for expansion | deployment is joined to the vicinity of the 2nd fold line 241b on the opposite side to the 1st fold line 241a of the 2nd fold line 241b. Further, the second fixed end 41b of the unfolding grip 4a is joined in the vicinity of the second fold line 241b between the first fold line 241a and the second fold line 241b of the fold part 24. In other words, in the vicinity of the second fold line 241b, the first fixed end 41a is joined to one part of the second fold line 241b, and the second fixed end 41b is connected to the other part of the second fold line 241b. Be joined.

  FIG. When the drape 1a shown in A is used, the folding center portion 242 is easily deployed by gripping and pulling the deployment gripping portion 4a by a doctor, nurse, or the like. Further, the belt-like member 31 is picked by a doctor, a nurse, or the like and deformed so as to be separated from the patient's face. As a result, the folding center portion 242 is separated from the patient's face, and a space 95 (see FIG. 4) is easily formed between the patient's face and the seat portion 2 as in the first embodiment. As a result, the sheet portion 2 is prevented from coming into close contact with the lower nose, mouth and cheeks of the patient, and the patient can easily breathe through the space 95.

  In the drape 1a, the fixed end 41 of the unfolding gripping portion 4a is divided into two parts and joined to the portions on both sides of the second folding line 241b, so that the deepest portion of the folding portion 24 (that is, the first folding line) The part in the vicinity of the second fold line 241b that is the part farthest from 241a can be easily pulled out. As a result, the space 95 can be formed larger easily. Note that the fixed end 41 of the deployment grip 4a may be divided into three or more divided ends. That is, the fixed end 41 of the deployment grip 4a is divided into a plurality of divided ends.

  Next, an ophthalmic drape according to the third embodiment of the present invention will be described. FIG. 8 is a plan view showing a drape 1b according to the third embodiment.

  Each belt-like member 31a is disposed at approximately the center in the left-right direction of the folding center portion 242 and overlaps the unfolding gripping portion 4 in plan view. In FIG. 8, the lower end portion of the band-shaped member 31 a located above the opening 20 is joined to the back surface 22 of the sheet portion 2 between the opening 20 of the upper covering portion 25 and the upper folding portion 24 (that is, The parts other than the lower end cross the folding part 24 in the vertical direction without being joined to the sheet part 2 on the back surface 22 side of the sheet part 2. The upper end portion of the belt-like member 31a located below the opening 20 is joined to the back surface 22 of the sheet portion 2 between the opening 20 of the upper covering portion 25 and the lower folding portion 24, and other than the upper end portion. The part crosses the folding part 24 in the vertical direction without being joined to the sheet part 2 on the back surface 22 side of the sheet part 2. In FIG. 8, in order to facilitate understanding of the drawing, the band-like member 31a is drawn with a thin solid line (the same applies to FIGS. 9, 15 and 16). In the state before using the drape 1b, the entire sheet portion 2 is folded in a small manner, as in the first embodiment.

  FIG. 9 is a plan view showing a state in which the drape 1b is spread on the patient's face 90. FIG. In FIG. 9, the drape 1b is arranged so that the opening 20 of the seat portion 2 overlaps the left eye of the patient, and the lower belt-like member 31a in FIG. It extends in the vertical direction from the portion 91 toward the mouth portion 93. 9 is disposed on the lower nose 911 and the mouth 93 of the patient. In the present embodiment, the upper end portion of the lower band-shaped member 31a is positioned substantially on the center in the vertical direction of the nose portion 91, and the lower end portion is below the mouth portion 93 (more preferably, from the contour of the lower jaw portion). (Position protruding downward).

  When the drape 1b is used, the folding center portion 242 is easily unfolded by gripping and pulling the lower unfolding grasping portion 4 in FIG. 9 by a doctor, nurse, or the like. Further, the lower belt-like member 31a is picked from the surface 21 side of the seat portion 2 by a doctor, a nurse, or the like and deformed so as to be separated from the patient's face 90. Thereby, as shown in FIG. 10, the folding center part 242 is separated from the patient's face 90, and a space 95 is easily formed between the patient's face 90 and the seat part 2 as in the first embodiment. Is done. As a result, the sheet portion 2 is prevented from coming into close contact with the patient's lower nose 911, mouth portion 93 and cheek portion 92, and the patient can easily breathe through the space 95. In addition, since the shape of the shape-retaining member 3a can be easily changed and maintained, an appropriate breathing space 95 can be easily formed in accordance with various patient face shapes. In the drape 1b, the shape-retaining member 3a includes a band-shaped member 31a extending from the patient's nose 91 toward the mouth 93 when in use, so that the seat 2 is placed in the patient's lower 911, mouth 93, and cheek 92. The space 95 is more reliably maintained as a result.

  Next, a drape according to a fourth embodiment of the present invention will be described. FIG. 11 is a plan view showing a state before the use of the drape 1c according to the fourth embodiment, and FIG. 12 shows a part of a cross section obtained by cutting the drape 1c at a position BB in FIG. FIG. As shown in FIGS. 11 and 12, in the drape 1 c, the two lower covering portions 26 positioned above and below the opening 20 each have another folding portion 24 a in addition to the folding portion 24. In addition to the deployment gripping portion 4, another deployment gripping portion 4 b is fixed to each lower covering portion 26. The other configuration of the drape 1c is the same as that of the drape 1 shown in FIG. 1, and the corresponding components are denoted by the same reference numerals.

  In the following description, the folding parts 24 and 24a are referred to as “first folding part 24” and “second folding part 24a”, respectively. The deployment grips 4 and 4b are referred to as a “first deployment grip 4” and a “second deployment grip 4b”, respectively. The second folding part 24 a is provided on the side opposite to the opening 20 of the first folding part 24. The second folding part 24a is folded at two folding lines 241c and 241d extending in the left-right direction at a position corresponding to the patient's nose or mouth. In the following description, the fold lines 241c and 241d are referred to as “third fold line 241c” and “fourth fold line 241d”, respectively.

  In the seat part 2, when the first folding part 24 and the second folding part 24 a are unfolded, the first folding line 241 a, the second folding line 241 a, The fold line 241b, the third fold line 241c, and the fourth fold line 241d are arranged in this order. Sites on both sides of the third fold line 241c (that is, two sites bordered by the third fold line 241c) are folded back so that the back surface 22 faces each other, and sites on both sides of the fourth fold line 241d are on the surface 21. Are folded so that they face each other. Thereby, the 2nd folding part 24a is formed. In other words, the second folding portion 24 a is also formed so that the sheet portion 2 is folded on the back surface 22 side, similarly to the first folding portion 24.

  As shown in FIG. 12, between the first fold line 241a and the second fold line 241b of the first fold part 24, and between the third fold line 241c and the fourth fold line 241d of the second fold part 24a. Then, the sheet | seat part 2 has overlapped on 3 layers. The three layers (that is, portions on both sides of the fold lines 241a to 241d) are joined to each other by a double-sided adhesive tape or the like at a fold end 243 indicated by parallel diagonal lines in FIG. On the other hand, in the folding center part 242 of each of the first folding part 24 and the second folding part 24a, the three superimposed layers are not joined. The width in the left-right direction of the folding center part 242 is 30 cm or more and 80 cm or less, and preferably 40 cm or more and 60 cm or less.

  As shown in FIGS. 11 and 12, the folding center portion 242 of the second folding portion 24 a is provided with a belt-like second deployment gripping portion 4 b formed of a nonwoven fabric, like the first deployment gripping portion 4. It is done. The second unfolding gripping portion 4b extends in the up-down direction at approximately the center of the folding center portion 242 in the left-right direction. The second unfolding gripping portion 4b is disposed between two layers of the three layers of the second folding portion 24a that are on both sides of the fourth folding line 241d, and is opposite to the opening 20 from the second folding portion 24a. Protrudes to the side. One end of the second unfolding gripping portion 4b (that is, the fixed end 41 that is the end close to the opening 20) is located near the fourth fold line 241d as indicated by a parallel diagonal line in FIG. Bonded to the surface 21 of the sheet portion 2. In other words, the second unfolding grip 4b extends from between the portions on both sides of the fourth fold line 241d from the fourth fold line 241d toward the third fold line 241c beyond the third fold line 241c.

  As shown in FIG. 12, the fixed end 41 of the second unfolding gripping portion 4b is hot only in the vicinity of the fourth fold line 241d and on the opposite side of the fourth fold line 241d from the third fold line 241c. Joined with a melt adhesive or the like. The vicinity of the fourth fold line 241d means a position closer to the fourth fold line 241d than the third fold line 241c or overlapping the fourth fold line 241d when the second fold part 24a is viewed in plan. To do. In the present embodiment, the edge on the fixed end 41 side of the second unfolding grip 4b approximately coincides with the fourth fold line 241d. In the second deployment gripping part 4b, parts other than the fixed end 41 are not joined to the sheet part 2.

  The length of the first deployment gripping portion 4 is longer than the length of the second deployment gripping portion 4b, and the free end 42 of the first deployment gripping portion 4 and the free end 42 of the second deployment gripping portion 4b are the same. And bonded to each other by a hot melt adhesive or the like. In FIG. 11, in order to facilitate understanding of the drawing, the width of the second deployment grip 4b is drawn larger than the width of the first deployment grip 4; The width of the portion 4 is equal to the width of the second deployment gripping portion 4b. Note that the width of the second deployment gripping portion 4b may be larger or smaller than the width of the first deployment gripping portion 4.

  When the drape 1c is used, the free ends 42 of the first deployment gripping portion 4 and the second deployment gripping portion 4b shown in FIG. 12 are gripped and pulled together by a doctor, a nurse, or the like, so that the first folding is performed. The part 24 and the second folding part 24a are easily deployed. As a result, as shown in FIG. 13, the folding center part 242 of the first folding part 24 and the second folding part 24a is separated from the patient's face 90, and the patient's face 90 and the seat are the same as in the first embodiment. A space 951 from the lower nose 911 and the mouth 93 to the left and right cheeks 92 is easily formed between the unit 2 and the unit 2. Further, the band-shaped member 31 is picked by a doctor, a nurse, or the like and deformed so as to be separated from the patient's face, whereby the upper covering portion 25 of the seat portion 2 is separated from the patient's nose portion 91 and the vicinity thereof, A space 952 continuous from the space 951 is formed between the upper covering portion 25 and the patient's face 90.

  In the drape 1c, the lower covering portion 26 of the seat portion 2 includes the first folding portion 24 and the second folding portion 24a, so that when the first folding portion 24 and the second folding portion 24a are unfolded, the space 951 is more stretched. Can be bigger. Thereby, it is prevented more reliably that the sheet | seat part 2 contact | adheres to a patient's nose lower part 911, the mouth part 93, and the cheek part 92. FIG. As a result, the patient can breathe more easily through the space 95 (that is, the space 951 and the space 952). In the drape 1c, a space 952 continuous to the space 951 is formed on the nose portion 91 by deformation of the shape retaining member 3, so that the patient can breathe more easily.

  In the drape 1 c, as shown in FIG. 12, the first deployment grip 4 and the second deployment grip 4 b are joined to each other at the free end 42. As a result, the first deployment grip 4 and the second deployment grip 4b can be easily gripped together. For this reason, the 1st folding part 24 and the 2nd folding part 24a can be pulled simultaneously, and the 1st folding part 24 and the 2nd folding part 24a can be developed simultaneously.

  The first deployment grip 4 and the second deployment grip 4b may be joined to each other on the way to the free end 42 (that is, between the fixed end 41 and the free end 42). Even in this case, by gripping and pulling the free end 42 of the first deployment grip 4 and / or the second deployment grip 4b, the first deployment grip 4 and the second deployment grip 4b is pulled simultaneously and the 1st folding part 24 and the 2nd folding part 24a can be expand | deployed simultaneously. From the viewpoint of simultaneously gripping the free end 42 of the first deployment grip 4 and the second deployment grip 4b, the first deployment grip 4 and the second deployment grip 4b are the third The fold line 241c is preferably joined at a position close to the free end 42 on the side opposite to the opening 20.

  Next, a drape according to a fifth embodiment of the present invention will be described. FIG. 14 is a partial cross-sectional view of the drape 1d according to the fifth embodiment, and corresponds to FIG. In the drape 1d, the shape of the second folding part 24b is different from the second folding part 24a of the drape 1c shown in FIG. Further, one unfolding gripping portion 4 is fixed to each lower covering portion 26. Other configurations of the drape 1d are the same as the configurations of the drape 1c shown in FIGS. 11 and 12, and the corresponding components are denoted by the same reference numerals.

  As shown in FIG. 14, the second folding part 24 b is provided on the side opposite to the opening 20 (see FIG. 11) of the first folding part 24. The second folding part 24b is folded at a third folding line 241c and a fourth folding line 241d extending in the left-right direction at a position corresponding to the patient's nose or mouth. In the second foldable portion 24b, in the state before use, the portions on both sides of the third fold line 241c are folded back so that the front surface 21 faces, and the portions on both sides of the fourth fold line 241d face each other. Wrapped like so. In the seat part 2, when the first folding part 24 and the second folding part 24 b are unfolded, the first folding line 241 a, the second folding line 241 a, The fold line 241b, the third fold line 241c, and the fourth fold line 241d are arranged in this order.

  The fixed end 41 of the unfolding grip 4 is joined to the surface 21 of the sheet portion 2 with a hot melt adhesive or the like between the second fold line 241b and the third fold line 241c. In the present embodiment, the fixed end 41 overlaps the first folding part 24 in a plan view, and the unfolding gripping part 4 is folded between the first folding line 241a and the fourth folding line 241d. It extends beyond the line 241d onto the second fold 24b (ie, the second fold 24b opposite to the patient). For example, when the fixed end 41 overlaps the second folding part 24b in plan view, the unfolding gripping part 4 exceeds the first folding line 241a between the first folding line 241a and the fourth folding line 241d. It may extend on the first folding part 24. That is, the deployment grip 4 extends beyond the first fold line 241a or the fourth fold line 241d.

  When the drape 1d is used, the free end 42 of the deployment grip 4 is gripped and pulled by a doctor, a nurse, or the like, so that the space between the second fold line 241b and the third fold line 241c of the seat portion 2 is increased. The first folding part 24 and the second folding part 24b are easily deployed by being pulled up. Further, the belt-like member 31 is picked by a doctor, a nurse, or the like and deformed so as to be separated from the patient's face. Thereby, the space 95 (refer FIG. 13) is easily formed between a patient's face and the sheet | seat part 2 similarly to the drape 1c.

  In the drape 1d, the lower covering portion 26 of the seat portion 2 has the first folding portion 24 and the second folding portion 24b, so that when the first folding portion 24 and the second folding portion 24b are unfolded, the space 95 is further expanded. Can be bigger. As a result, the patient can breathe more easily through the space 95. In the drape 1d, the first folding portion 24 and the second folding portion 24b can be easily and simultaneously pulled by pulling one unfolding gripping portion 4 fixed between the second folding line 241b and the third folding line 241c. Can be deployed. Further, since the deployment grip 4 extends beyond the first fold line 241a or the fourth fold line 241d, the deployment grip 4 can be easily gripped.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

  For example, in the drape 1 according to the first embodiment, the fixed end 41 of the unfolding gripping portion 4 is joined to the surface 21 of the sheet portion 2 only between the second fold line 241b and the first fold line 241a. May be. In this way, the fixed end 41 of the deployment grip 4 is joined only to one side of the second fold line 241b, so that the deployment grip 4 can be easily attached to the previously formed fold 24. Can be joined. It should be noted that when the unfolding gripping portion 4 is joined before the folding portion 24 is formed, the fixed end 41 of the unfolding gripping portion 4 straddles the second folding line 241b and both sides of the second folding line 241b. It may be joined to this part.

  The unfolding grips 4 and 4a may be formed of various materials other than a nonwoven fabric such as a plastic film. The unfolding gripping portion is not limited to a belt shape, and may be a string shape or a sheet shape. However, from the viewpoint of reducing the material used as the deployment gripping portion and easily gripping the deployment gripping portion, it is more preferable that the deployment gripping portion has a strip shape. The unfolding gripping part may be detachably fixed to the sheet part 2 so that it can be detached from the sheet part 2 as necessary after the folding part is unfolded.

  The shape of the shape retaining member may be variously changed. For example, in the drape 1e shown in FIG. 15, the shape-retaining member 3b includes four strip members 31b. The belt-shaped member 31b is linearly formed from the vicinity of the opening 20 in a direction inclined with respect to the vertical direction and the horizontal direction in FIG. 15 (that is, a direction inclined with respect to each side of the substantially rectangular sheet portion 2). extend. In FIG. 15, the distance between the left and right directions of the two strip members 31b located below the opening 20 increases from the upper side to the lower side in FIG. In other words, the two belt-like members 31b are arranged in a square shape whose upper end is closer to each other than the lower end. The two belt-like members 31b positioned above the opening 20 are arranged in an inverted C shape whose lower end is closer to each other than the upper end. In each belt-like member 31b, an end portion close to the opening 20 in the vertical direction is joined to the back surface 22 of the sheet portion 2 between the opening 20 of the upper covering portion 25 and the folding portion 24, and portions other than the end portion are The folding part 24 is traversed in the vertical direction without being joined to the sheet part 2 on the back surface 22 side of the sheet part 2.

  When the drape 1e is used, the two belt-like members 31b on the lower side of the opening 20 in FIG. 15 are directed from the patient's nose 91 to the left and right cheeks 92 (that is, with the mouth 93 in between). A drape 1e is placed on the patient's face 90 to extend. The upper ends of the two belt-like members 31b are located on both the left and right sides of the approximate center in the vertical direction of the nose 91, and the lower ends are below the left and right cheeks 92 (that is, below the contour of the lower jaw). It is located at the protruding position. In the drape 1e, the folding center portion 242 is easily deployed by the lower grasping portion 4 in FIG. 15 being grasped and pulled by a doctor, a nurse, or the like. Further, the two lower belt-like members 31b are picked from the surface 21 side of the seat portion 2 by a doctor, a nurse, or the like and deformed so as to be separated from the patient's face 90. Thereby, a space from the lower nose 911 and the mouth portion 93 to the left and right cheek portions 92 is easily formed between the patient's face 90 and the sheet portion 2.

  Moreover, in the drape 1f shown in FIG. 16, the shape-retaining member 3c includes eight strip-shaped members 31c. Four belt-like members 31c joined in a lattice pattern are disposed on the two folding parts 24, respectively. Of the four strip-shaped strip members 31 c, the end portion on the opening 20 side of the two strip-shaped members 31 c extending in the vertical direction is between the opening 20 of the upper covering portion 25 and the folding portion 24. The other portions of the two belt-like members 31c and the other two belt-like members 31c extending in the left-right direction are not joined to the sheet portion 2.

  When the drape 1f is used, the folding center portion 242 is easily unfolded by the lower grasping portion 4 in FIG. 16 being grasped and pulled by a doctor, a nurse, or the like. Further, the lower four belt-like members 31c are picked from the surface 21 side of the seat part 2 by a doctor, a nurse, or the like, and the center part 315 protrudes in a direction away from the patient's face as shown in FIG. Deformed into a dome shape. Thereby, a space from the lower nose 911 and the mouth portion 93 to the left and right cheek portions 92 is easily formed between the patient's face 90 and the sheet portion 2.

  In the drapes according to the first to fourth embodiments, the folding part may be formed such that the sheet part 2 is folded on the surface 21 side. That is, in a state in which the folded portion is unfolded, the portions on both sides of the odd-numbered fold line counted from the opening 20 are folded back so that the front surface 21 faces, and the portions on both sides of the even-numbered fold line face each other. Wrapped to

  For example, in the drape 1 shown in FIG. 2, the folded portion 241a is folded so that the portions on both sides of the fold line 241a face each other and the portions on both sides of the fold line 241b are folded so that the back surface 22 faces each other. 24 is formed. In this case, the fixed end 41 of the unfolding grip 4 is joined to the surface 21 of the sheet 2 in the vicinity of the fold line 241a. Further, the unfolding grip 4 extends from the fold line 241a toward the fold line 241b from between the portions on both sides of the fold line 241a beyond the fold line 241b.

  Further, in the drape 1c shown in FIG. 12, the portions on both sides of the fold lines 241a and 241c are folded so that the front surface 21 faces, and the portions on both sides of the fold lines 241b and 241d are folded so that the back surface 22 faces each other. Thus, the folding parts 24 and 24a are formed. In this case, the fixed ends 41 of the deployment gripping portions 4 and 4b are joined to the surface 21 of the sheet portion 2 in the vicinity of the fold line 241a and the fold line 241c, respectively. The unfolding grip 4 extends from the fold line 241a toward the fold line 241b from between the portions on both sides of the fold line 241a beyond the fold line 241b. The unfolding gripping portion 4b extends from the fold line 241c toward the fold line 241d from between the portions on both sides of the fold line 241c beyond the fold line 241d.

  On the other hand, in the drape 1d shown in FIG. 14, the portions on both sides of the first fold line 241a and the fourth fold line 241d are folded back so that the surface 21 faces, and the both sides of the second fold line 241b and the third fold line 241c are. The first folding part 24 and the second folding part 24b may be formed by folding the part so that the back surface 22 faces. By adopting such a structure, the space 95 can be made larger when the first folding part 24 and the second folding part 24b are expanded, like the drape 1d. In addition, the fixed end 41 pulls the unfolding grip portion 4 fixed to the surface 21 of the seat portion 2 between the second fold line 241b and the third fold line 241c, whereby the first fold portion 24 and the second fold portion 24 The folding part 24b can be easily unfolded simultaneously.

  In the folded part of the drape according to the above embodiment, the joining of the sheet part 2 at the folded end part 243 may not be performed. Further, each lower covering portion 26 of the sheet portion 2 may be provided with three or more folding portions.

  In the above-mentioned drape, the shape-retaining member does not necessarily have to be linear or flat as long as the drape can be folded small before use, and if it can be fitted to the general patient's face. The shape of the shape member may not be changeable. In the drape, even when the shape retaining member is made of a material other than resin (for example, a metal such as aluminum (Al)), the patient can easily breathe. Further, in the drape, two openings corresponding to both eyes of the patient may be formed in the seat portion 2, and in this case, the shape retaining member and the folding portion are provided only below the two openings.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
