Abstract
Description
[Technical Field]
[0001] The present invention relates to a face plate for a stoma appliance used in an excrement collection appliance for temporarily storing excrement, discharged fluid, gas, exudate, secretions, etc. (hereinafter collectively referred to as "excrement"; the same applies hereinafter) excreted from an excretory opening created in the human body, and to a stoma appliance equipped with the same. [Background technology]
[0002] In cases where a person is unable to control fecal or urinary excretion at will, or where there is a disease of the digestive or urinary system, a surgical procedure may be performed to guide the intestines or ureters to the body surface, creating a stoma on the body surface. Those with a stoma need to have a pouch attached to the stoma that can temporarily store waste from the stoma. People who have openings or wounds on the surface of their body due to other diseases also need a pouch attached around the opening or wound to handle waste discharged by drainage or other means.
[0003] For example, Patent Document 1 discloses an excrement collection device comprising a skin-adhering member that is adhesively fixed around an opening in a living body, a ring-shaped first flange fixed to the non-skin-adhering side of the skin-adhering member, and a ring-shaped second flange that can fit into the first flange, wherein the skin-adhering member has an opening that corresponds to the opening in the living body, and either the first flange or the second flange has a ring-shaped protrusion made of a hard resin material, and the other flange has a fitting device that has a ring-shaped grooved protrusion made of hard resin that can fit into the ring-shaped protrusion.

DETAILED DESCRIPTION OF THE INVENTION
[0013] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the embodiment described below shows an example of a typical embodiment of the present invention, and the scope of the present invention is not limited thereto. Furthermore, the present invention can be achieved by arbitrarily or appropriately combining any of the techniques, embodiments, examples, and modifications described in this specification.
[0014] In the following description of the embodiments, configurations may be described using terms including "approximately," such as "approximately parallel" and "approximately perpendicular." For example, "approximately parallel" does not only mean completely parallel, but also means substantially parallel, that is, including a state in which the configuration is deviated from the completely parallel state by, for example, a few percent (which may be "°" or "mm") (for example, a deviation within a range of 0.05, 0.1, 0.5, 1, 2, or 3% or less). The same applies to other terms including "approximately." Furthermore, each drawing is a schematic diagram and is not necessarily an exact illustration.
[0015] Unless otherwise specified, in the drawings, "upper" means the upper direction or upper side in the drawing, "lower" means the lower direction or lower side in the drawing, "left" means the left direction or left side in the drawing, and "right" means the right direction or right side in the drawing. Furthermore, in the drawings, the same or equivalent elements or members are given the same reference numerals, and redundant explanations are omitted. Furthermore, in the present invention, one or more types selected from these may be used for the examples described in this specification.
[0016] 1. Background and Overview of the Invention The present inventors focused on the fact that, when ostomates wear a stoma appliance, body movements can cause wrinkles around the stoma and pressure on the abdomen where the faceplate contacts. They attempted to improve the discomfort and ease of use for ostomates. They discovered that adjusting the positional relationship between the inner diameter of the flat plate and the inner diameter of the skin barrier in the faceplate can prevent wrinkles around the stoma caused by body movements and reduce pressure on the abdomen where the faceplate contacts. Based on this finding, they completed the present invention. They have now provided a faceplate for a stoma appliance in which the inner diameter of the skin barrier is positioned within the inner diameter of the flat plate, and a stoma appliance including the faceplate. Furthermore, the flat faceplate of the present invention has the advantages of preventing wrinkles in the skin barrier and reducing pressure on the abdomen compared to convex faceplates.
[0017] In this specification, an appliance for temporarily storing excrement, excretory fluids, gas, exudates, secretions, waste products, etc. (hereinafter collectively referred to as "excrement"; the same applies below) from within or on the surface of a living body is referred to as an excrement storage appliance, and such excrement storage appliance may also be referred to as a stoma appliance.
[0018] This embodiment provides a base plate for a stoma appliance, which includes a flat plate having a first opening, a skin barrier having a second opening, and an opening (e.g., a stoma insertion hole) composed of at least the first opening and the second opening, with the second opening located within the first opening of the flat plate, and a stoma appliance comprising the same. The opening (e.g., the stoma insertion hole) provided in the base plate is preferably composed of at least the first opening and the second opening, which are arranged with approximately the same size as the first opening. The centers of the openings provided in the base plate are preferably positioned at approximately the same positions as the centers of the first opening and the second opening, and the centers of the first opening and the second opening are preferably positioned at approximately the same positions. The width of the flat plate is preferably greater than 15 mm.
[0019] Furthermore, a preferred aspect of this embodiment is a face plate for a stoma appliance, which comprises a flat plate having a first opening, a skin protective agent having a second opening, and an opening (e.g., a hole for inserting a stoma) composed of at least the first opening and the second opening, and the plate end toward the center of the flat plate is located within the same or nearby area outward from the second opening.
[0020] In another aspect of this embodiment, the flat plate is preferably a flat plate for use as a base plate for a stoma appliance. In a more preferred embodiment, a flat plate can be provided that has a first opening for forming an opening (e.g., a stoma insertion hole) in the base plate, and that the plate edge toward the center is positioned within the same or adjacent area as a second opening in the skin barrier on the base plate for forming the stoma insertion hole.
[0021] As another aspect of this embodiment, a base plate for a waste collection device, which includes a flat plate having a first opening, a skin protective agent having a second opening, and an opening (also called a hole) composed of at least the first opening and the second opening, with the second opening located within the first opening of the flat plate, and a waste collection device including the same can be provided. This can achieve another object of suppressing wrinkles that occur around the stoma due to body movement when wearing the waste collection device for waste discharged through a drain for drainage or a stoma for defecation, etc., and reducing the surface pressure generated at the attachment portion where the base plate comes into contact.
[0022] In this specification, the contents of each configuration, method, etc. described in any of sections such as "1.", "2.", "3.", etc. may be omitted as appropriate in the explanation of each section, and the explanation contents of each section (each configuration, each method, etc.) may be adopted as appropriate to apply to this embodiment of the present invention in other sections.

Face plate according to this embodiment This embodiment can provide a base plate comprising a flat plate having a first opening and a skin protector having a second opening, the second opening being configured to be positioned within the first opening of the flat plate. The base plate preferably has a hole formed by at least a first opening and a second opening, and more preferably the hole is a hole for inserting a stoma. The base plate is preferably a base plate used for a stoma appliance, and more preferably a base plate for a stoma appliance that can be attached to the abdomen. The face plate is preferably configured so that its edge toward the center of the face plate is located within the same or adjacent area outward from the second opening in the skin barrier, which defines the first opening and the hole. This "within the same or adjacent area" preferably refers to a ratio of [diameter of the first opening in the face plate / diameter of the second opening in the skin barrier] between 1 and 1.4 times the diameter of the second opening in the skin barrier. The width of the face plate is preferably greater than 15 mm. Furthermore, the plate bending stress in the face plate is preferably 2N or more and 30N or less.
[0024] The base plate according to this embodiment may be a medical component, such as a medical component used for one or more of an ostomy appliance pouch, a drainage pouch, a fecal bag, a urine collection bag, a urine collection bag, etc. In the case of a base plate used as a medical component, it may be a base plate for a waste collection appliance.
[0025] The face plate of this embodiment will be described with reference to FIGS. 1 to 4, but this embodiment is not limited to these drawings and symbols.
[0026] 2-1.Flat plate FIG. 1 shows a back view (FIG. 1A) and a front view (FIG. 1B) of a flat plate 10, where FIG. 1A is a back view of the flat plate 10 seen from the side that contacts the pouch 30, and FIG. 1B is a front view of the flat plate 10 seen from the side that contacts the skin protective agent 20. The flat plate 10 preferably has a hollow, approximately circular shape with a substantially circular opening 15 in the center when viewed from either the front or back. When the flat plate 10 is viewed in an orthographic projection, the shape when viewed from the left-right direction (left side view, right side view) and / or the top-bottom direction (top view, bottom view) is not particularly limited. For example, as shown in Figures 1C and 4, the flat plate 10 is preferably a shape with a flat surface on both or either one of its surfaces (e.g., a rectangular shape (including a square shape)), more preferably a hollow rectangular shape with an opening 15 in the center. Note that the hollow rectangular surface may have a flat convex or concave portion for attachment to a pouch or skin protective agent.
[0027] 1A shows a flat plate 10 having a single, generally flat, convex periphery located midway between the center and the periphery, with a central opening 15. The flat plate 10 is preferably provided with a storage section 30 on its rear surface. This convex periphery may be omitted, or one or more may be provided. For example, it is preferable to have one or more flat convex peripheries for attachment (bonding, adhesion, etc.) to the storage section 30, etc.
[0028] 1B shows a flat plate 10 having a generally flat surface and a central opening 15. The flat plate 10 is preferably provided with a skin protectant 20 on its front portion, thereby forming a face plate 100.
[0029] The size of the flat plate 10 used in this embodiment is not particularly limited, but it is preferably a size that can be used as a face plate for a waste collection appliance, and more preferably a size that can be used as a face plate for a stoma appliance.
[0030] The flat plate 10 preferably has a first opening 15. The first opening 15 is preferably located approximately in the center of the flat plate 10, and / or the first opening 15 is preferably formed to be equal to or larger than the second opening 25 of the skin protective agent 20 that is joined to the flat plate 10. The size of the first opening 15 is preferably approximately the same as or larger than the size of the second opening 25 of the skin protective agent 20 constituting the base plate 100, and more preferably approximately the same size. When the size of the second opening is taken as 100%, the size of the first opening and the second opening being approximately the same may mean that there is a dimensional difference of 0.05%, 0.1%, 0.5%, 1%, 2%, or 3% or less, and the smaller this difference is the better, and they may even be the same size.
[0031] In this specification, the criteria for determining size are not particularly limited, but it is preferable to determine the size on a plane (X-axis and / or Y-axis), and in this case, it is desirable to determine the area or diameter. Furthermore, the diameter is not particularly limited, and examples thereof include the maximum major axis, maximum minor axis, diameter, radius, inner diameter, and outer diameter.
[0032] Furthermore, it is preferable that the center of the first opening 15 is disposed so as to be approximately coincident with the center of the flat plate 10. The center of the first opening 15 may be offset from the center (or center line) of the flat plate 10 by, for example, 0.05 mm, 0.1 mm, 0.5 mm, 1 mm, 2 mm, or 3 mm or less, and the smaller this offset is the better, and it may be coincident with the center of the flat plate. It is also preferable that the center of the first opening 15 is disposed so as to be approximately coincident with the center of the face plate 100, and this "approximately identical" is essentially the same as the above-mentioned "approximately identical," and in this case, it is preferable that the offset from the center of the face plate 100 is within the above-mentioned numerical range (for example, 0.1 mm or less), and it may be coincident with the center of the face plate 100.
[0033] In this specification, the "center" may be "on the center line" or "on the central axis," and the same center may be on the same center line (on the central axis).
[0034] In addition, when aligning the first opening 15 (preferably the inner diameter) of the flat plate 10 with the second opening 25 (preferably the inner diameter) of the skin protective agent 20, it is more preferable that the center of the first opening and the center of the second opening are in approximately the same position, and this may form an opening or hole in the face plate. This "approximately the same" is essentially the same as the above-mentioned "approximately the same." In this case, a deviation from either center within the above-mentioned numerical range (e.g., 0.1 mm or less) is preferred, and both centers may be in the same position.
[0035] The shape of the flat plate or the shape of the first opening is not particularly limited, but examples include a substantially elliptical shape, a substantially circular shape, and a polygonal shape (e.g., a polygonal shape with 3, 4, 5, 6, 8, etc. sides; a regular polygonal shape such as a rectangle, a parallelogram, or a square), and one or more types selected from these are preferred, with a substantially circular shape being preferred. The shape of the first opening is preferably matched to the cross-sectional shape of the outer periphery of the stoma (e.g., the insertion portion) or to the shape of the second opening, and it is preferable that the corresponding or opposing shapes are the same. In the case of a polygonal shape, the center may be the intersection of the diagonals.
[0036] The first opening in the flat plate is preferably used as a hole for the waste flow path, and more preferably, a hole into which the tip of a waste flow path such as a stoma is inserted is formed together with the second opening in the skin protective agent.
[0037] The outer diameter (preferably diameter) of the flat plate is not particularly limited, but a suitable lower limit is preferably 70 mm or more, more preferably 80 mm or more, and even more preferably 90 mm or more, and a suitable upper limit is preferably 140 mm or less, more preferably 130 mm or less, even more preferably 120 mm or less, and even more preferably 110 mm or less, with a suitable numerical range being 80 to 120 mm. The outer diameter of the flat plate may be the maximum major axis of the flat plate. The outer diameter of the flat plate may also be the diameter when viewed from the front or back.
[0038] The plate width of the flat plate is not particularly limited, but a suitable lower limit is preferably 10 mm or more, more preferably 15 mm or more, even more preferably more than 15 mm, more preferably 16 mm or more, more preferably 17 mm or more, more preferably 18 mm or more, more preferably 19 mm or more, and more preferably 20 mm or more, and a suitable upper limit is preferably 50 mm or less, more preferably 40 mm or less, 35 mm or less, or 30 mm or less. The plate width is a value calculated by dividing the outer diameter of the flat plate by the inner diameter of the flat plate by 2.

The diameter of the first opening may be the diameter when viewed from the front or back, and may be the maximum long diameter.
[0040] The thickness of the flat plate is not particularly limited, but a suitable lower limit is preferably 0.3 mm or more, more preferably 0.5 mm or more, and even more preferably 0.8 mm or more, and a suitable upper limit is preferably 2 mm or less, more preferably 1.5 mm or less, and even more preferably 1.3 mm or less, with a suitable numerical range of 0.8 to 1.3 mm. The thickness of the flat plate is the thickness when viewed from the right side or left side.
[0041] The material of the flat plate is not particularly limited. From the viewpoint of suppressing wrinkles on the skin, a flexible resin is preferred, and a thermoplastic resin is more preferred. The thermoplastic resin is preferably selected from resins generally used for flat plates of stoma appliances, such as polyolefin resins, of which polyethylene (PE) resin, polypropylene (PP) resin, and ethylene-vinyl acetate copolymer (EVA) resin are preferred. In this embodiment, the material of at least the portion that is bonded to and supports the skin protective agent is preferably selected from the above-mentioned resins. One or more of these may be selected. In this specification, the desired material for the flat plate is preferably prepared by blending multiple materials to achieve a plate bending stress of 2N to 30N, and more preferably within a suitable numerical range of plate bending stress.
[0042] 2-2. Skin barrier 2 to 4 show a skin protective agent 20, which preferably has a second opening 25. The skin protective agent 20 is preferably used to fix or support a stoma appliance to the skin around an excretion hole (e.g., a stoma) for storing fluids such as feces, urine, or body fluids excreted from the excretion hole, such as an artificial anus, an artificial bladder, or various fistula products. The skin protective agent 20 preferably has one surface for bonding to the surface of the flat plate 10, and the other surface for bonding to the skin around the excretion hole.
[0043] When viewed from either the front or back of the skin protective agent 20, it is preferable that the skin protective agent 20 has a hollow, approximately circular shape with a substantially circular opening 25 in the center. When the skin protective agent 20 is viewed using an orthographic projection, the shape when viewed from the left-right direction (left side view, right side view) and / or the top-bottom direction (top view, bottom view) is not particularly limited, but for example, as shown in Figure 4, a shape with flat surfaces on both or either side (such as a rectangular shape (including a square shape)) is preferred, and a hollow rectangular shape (including a square shape) with an opening 25 in the center is more preferred.
[0044] The size of the skin protective agent 20 used in this embodiment is not particularly limited, but it is preferably a size that can be used as a face plate for a waste collection appliance, and more preferably a size that can be used as a face plate for a stoma appliance.
[0045] The skin protective agent 20 preferably has a second opening 25. The second opening 25 is preferably located approximately in the center of the skin protective agent 20, and / or the second opening 25 is preferably formed to be equal to or smaller in size than the first opening 15 of the flat plate 10 that is joined to the skin protective agent 20.
[0046] The size of the second opening 25 is preferably approximately the same as or smaller than the size of the first opening 15 of the flat plate 10 constituting the face plate 100, and more preferably approximately the same size. When the size of the first opening is taken as 100%, the second opening and the first opening being approximately the same size may have a dimensional deviation of 0.05%, 0.1%, 0.5%, 1%, 2%, or 3% or less, and the smaller this deviation is the better, and they may be the same size.
[0047] Furthermore, the center of the second opening 25 is preferably positioned so that it is substantially coincident with the center of the skin protective agent 20. The center of the second opening 25, which is positioned so that it is substantially coincident with the center of the skin protective agent 20, may be offset from the center (or center line) of the skin protective agent 20 by, for example, 0.05 mm, 0.1 mm, 0.5 mm, 1 mm, 2 mm, or 3 mm or less; the smaller this offset, the better; and the second opening 25 may be aligned with the center of the skin protective agent 20. Furthermore, the center of the second opening 25 is preferably positioned so that it is substantially coincident with the center of the base plate 100; "substantially identical" is essentially synonymous with "substantially identical" as described above; in this case, the offset from the center of the base plate 100 within the above-described numerical range (e.g., 0.1 mm or less) is preferable, and the second opening 25 may be aligned with the center of the base plate 100.
[0048] The shape of the skin protective agent or the shape of the second opening is not particularly limited, but can be any of the shapes described above for the "flat plate shape or first opening shape," and examples include a generally elliptical shape, a generally circular shape, a polygonal shape, etc. One or more shapes selected from these are preferred, with a generally circular shape being preferred. The shape of the second opening is preferably matched to the cross-sectional shape of the periphery of the stoma (e.g., the insertion portion) or to the shape of the first opening, and it is preferable that these shapes are the same. The second opening is preferably used as a hole for the waste flow path, and more preferably, a hole into which the tip of a waste flow path such as a stoma can be inserted can be formed together with the first opening of the flat plate.
[0049] The shape and holes of the skin protective agent or the second opening, and the relationship with the flat plate and the first opening can be appropriately determined from the configuration described above in "2-1. Flat Plate." For example, the shape of the second opening is preferably approximately circular, and if it is polygonal, the center may be the intersection of the diagonals.
[0050] The outer diameter (preferably the diameter) of the skin protective agent is not particularly limited, but is preferably large enough to cover the size of the flat plate, and is preferably equal to or larger than the size or outer diameter of the flat plate. The outer diameter of the flat plate is preferably 80 to 130 mm, more preferably 90 to 120 mm. The outer diameter of the skin protective agent may also be the maximum major axis of the skin protective agent. The outer diameter of the skin protective agent may also be the diameter when viewed from the front or back. The thickness of the skin protective agent is not particularly limited, but may be, for example, approximately 0.1 to 2 mm, such as the thickness of commercially available skin protective agents for stoma appliances. The thickness of the skin protective agent is measured when viewed from the right or left side.
[0051] The inner diameter of the skin protective agent is not particularly limited, but may or may not contact the stoma opening. The inner diameter (preferably diameter) of the skin protective agent preferably has a lower limit of 5 mm or more, more preferably 10 mm or more, or 20 mm or more, or 25 mm or more, or 30 mm or more, and a preferred upper limit of 60 mm or less, more preferably 50 mm or less, or 45 mm or less, or 40 mm or less, with a preferred numerical range of 10 to 50 mm. The inner diameter of the skin protective agent may be the diameter of the second opening. The diameter of the second opening may be the diameter when viewed from the front or back, and may be the maximum major axis.
[0052] The skin protective agent preferably has a skin protective effect (the effect of maintaining the physiological state of the skin) and preferably has adhesive properties in the area that comes into contact with the skin. The substrate for the skin protective agent is not particularly limited, but examples include nonwoven fabrics, woven fabrics, films, and foam sheets. The composition constituting the skin protective agent is not particularly limited, and conventional compositions or commercially available products can be used.
[0053] 2-3. Face plate The base plate 100 used in this embodiment preferably comprises a flat plate 10 having a first opening 15 and a skin protective agent 20 having a second opening 25. The base plate 100 preferably has an opening, more preferably an opening consisting of at least the first opening 15 and the second opening 25, even more preferably a hole for an excrement flow path into which the tip of an excrement flow path (e.g., a stoma, drain tube, catheter tube, etc.) constructed in or on the surface of the living body is inserted, and even more preferably a hole for inserting a stoma. The opening may also be a hole.
[0054] It is preferable that the center of the opening in the face plate 100 is positioned approximately identical to the center of the first opening 15 or the center of the second opening 25, or the center of both, and it is more preferable that it is positioned approximately identical to the centers of the first opening and the second opening. Furthermore, the shape of the first opening 15 and the shape of the second opening 25 are preferably substantially the same or the same shape. The shape of the flat plate 10 and the shape of the skin protective agent 20 are preferably substantially the same or the same shape.
[0055] The opening, which is at least composed of the first opening 15 and the second opening 25, is typically a free-cut type that can be freely adjusted by cutting or the like to fit the size (outer diameter) of the tip portion to be inserted (e.g., a stoma), a pre-cut type that is pre-adjusted to a fixed size by cutting or the like, or a moldable type that allows the size of the hole (e.g., a hole for stoma insertion) to be adjusted with a finger. In this embodiment, one or more types selected from these can be used, but pre-cut types are preferred from the viewpoint of aligning the first opening and the second opening. In addition, in this embodiment, in the case of a free-cut type, it is preferable that the openings can be positioned within a desired range of the same or nearby areas when adjusted by cutting or the like. In the case of a moldable type, it is preferable that the opening size can be adjusted to be positioned within a desired range of the same or nearby areas when adjusted.
[0056] Furthermore, the face plate 100 is preferably configured so that the second opening 25 (preferably the outer periphery of the second opening) is located within the first opening 15 (preferably the outer periphery of the first opening) of the flat plate 10. Furthermore, the face plate 100 is preferably configured so that the plate end toward the center of the flat plate 10 is located within the range of the same or nearby area located outward from the second opening 25. Furthermore, the range of the same or nearby area can be set by the ratio of the inner diameter of the first opening / the inner diameter of the second opening described above.

[0078] The effects of the present invention will be specifically described below with reference to examples, etc. However, the scope of the present invention is not limited to the examples described in this specification.
[0079] <Production Example 1> Each flat plate used in the present Examples was manufactured by molding a mold corresponding to Figures 1 and 2 based on the information on each flat plate of Examples 1 to 7 and Comparative Example 1 shown in Tables 1 and 2, and injection molding using a thermoplastic resin. The thermoplastic resin used in Examples 1 to 3 and Comparative Example 1 was low-density polyethylene. The thermoplastic resin used in Example 6 can be low-density polyethylene, and the thermoplastic resin used in Example 7 can be high-density polyethylene or polypropylene. The thermoplastic resins used in Examples 1 to 7 and Comparative Example 1 are commercially available products. The plate width (mm) in the tables is a value calculated by dividing the outer diameter of the flat plate by the inner diameter of the flat plate by 2.
[0080] For Comparative Example 2 in Table 1 below, a commercially available convex plate was obtained, and the difference between the height of the outer periphery and the height of the inner diameter was 4 mm. For the plates of Comparative Examples 1 and 3 and Examples 1 to 7, the plate on which the skin protective agent is to be applied was placed in contact with the tabletop, and when the outer periphery of the plate was pressed with a finger in a few places, almost no shaking was felt, so they were designated flat plates.
[0081] The skin protective agent used in this Example is the commercially available CellCare (R) One plate was obtained and cut to the desired size. Each panel used in this Example was obtained by using the flat plate and skin protective agent described above, adjusting the center of the inner diameter of the skin protective agent and the center of the inner diameter of the plate to be in the same position (on the same central axis), and then joining them as shown in Figure 2.
[0082] <Compression test (wrinkle prevention evaluation)> (1) A gel measuring 200 mm x 200 mm x 10 mm was prepared using a human skin gel concentrate (manufactured by Exseal Co., Ltd.) with a hardness of 0. This gel was placed on a table for the following compression. (2) Self-care (R) A hole of a size corresponding to the inner diameter of the plate listed in the table was drilled in the skin barrier No. 1. (3) The plate was attached to the skin barrier using double-sided tape (NITTO No. 5000NS), with the center of the inner diameter of the plate and the center of the inner diameter of the skin barrier aligned (on the same central axis). (4) The product prepared in (3) was attached to the center of the top surface of the gel prepared in (1) in both the vertical and horizontal directions. A ruler was placed on the desk so that the distance between the left and right ends of the compressed gel could be measured when the sides of the gel were compressed from both sides. (5) The panelists lightly touched the left and right ends of the lateral sides of the gel to which the (3) preparation had been attached (around the diameter of the plate) with the palms of their hands, and then compressed the plate until the outer diameter (the shortest distance between the left and right ends of the curved plate (the distance between the left and right ends of the gel after compression)) was 6 cm. (6) Panelists maintained the above compression and evaluated the total number of wrinkles in the skin barrier that connected to the inner diameter of the skin barrier as follows: Wrinkles in the gel that connected to the inner diameter of the skin barrier could cause leakage. Evaluation criteria: Rating point 5: 0 wrinkles, rating point 4: 1-3 wrinkles, rating point 3: 4-6 wrinkles, rating point 2: 7-9 wrinkles, rating point 1: 10 or more wrinkles. The evaluation scores in Tables 1 and 2 are the average scores when the number of panelists in this test was three, with each panelist taking one test.
[0083] <Surface pressure test (evaluation of discomfort)> (1) Self-care (R) The skin barrier agent No. 1 was attached to the plate using double-sided tape (NITTO No. 5000NS). (2) The product prepared in (1) was attached next to the navel of the panelist. (3) The panelists performed a sensory evaluation of the rebound sensation of the abdominal wall when bending forward at 45 degrees, according to the following evaluation criteria. Evaluation criteria: Rating point 5: No repulsion, Rating point 4: Repulsion weaker than standard 3, Rating point 3 (standard 3): Self care (R) 2. The same rebound as F, rating 2: The rebound is stronger than standard 3, rating 1: Cannot bend. The evaluation scores in Table 2 are based on the number of panelists in this test: 3, with each panelist taking 1 test, and are the average evaluation scores when these are added together.
[0084] <Plate bending stress test> (1) The test was carried out using a universal testing machine (Shimadzu Corporation; AGS-X). (2) The upper and lower ends (diametrically) of the outer edge of the vertically standing plate were gripped with the upper and lower chucks of the universal testing machine, and the plate was compressed 35 mm in the diametric direction at 1 mm / sec from the gripped upper and lower ends. (3) The maximum repulsive force (N) during the measurement was measured as the bending stress. The evaluation scores in Tables 1 and 2 are the average of three tests.
[0085] <Test Example 1>
[0086] [Table 1]
[0087] [Table 2]
[0088] <Consideration> As shown in Table 1, it was confirmed that wrinkles can be suppressed and discomfort caused by surface pressure can be reduced by using a face plate in which the center of the flat plate and the center of the skin protective agent are on the same central axis and the opening (inner diameter) of the skin protective agent is positioned within the opening (inner diameter) of the flat plate. It was considered that using a flat plate as in Examples 1 to 3 as a face plate is more desirable from the perspective of wrinkle suppression and discomfort caused by surface pressure than using a convex plate as in Comparative Example 2. More specifically, it is preferable that the plate edge toward the center of the flat plate be located within the same or adjacent area outward from the opening of the skin protective agent. In Comparative Example 3, the plate width is narrow and there are joints, making it thick, leading to poor flexibility and discomfort. It was considered that the face plates used in one-piece orthoses such as those in Examples 1 to 3 are more preferable from the perspectives of preventing wrinkles and reducing discomfort due to surface pressure. Since this favorable range of the same or adjacent region is 50 mm / 37 mm = 1.35 in Example 1, 37 / 32 = 1.16 in Example 2, and 37 / 37 in Example 3, it is more preferable that the range be 1 to 1.4 times the opening (inner diameter) of the skin protective agent. The width of the flat plate is preferably greater than 15 mm, more preferably 20 mm or more, and even more preferably 25 mm or more. Taking into account commercially available stoma appliances, it was considered preferable that the inner diameter of the flat plate be approximately 20 to 60 mm.
[0089] From the viewpoint of suppressing wrinkles and reducing discomfort from the surface pressure, it was confirmed that the surface pressure of the face plate used for the flat plate is preferably 2N to 30N, and from the viewpoint of even better reduction in discomfort from the surface pressure, it was considered that the pressure should be more preferably 2N to 10N, and even more preferably about 2N to 8N. A more preferable range for both suppressing wrinkles and reducing discomfort from the surface pressure was considered to be 3N to 8N.
[0090] In this specification, for convenience, explanations may be made using numbers or letters such as "first, second, third...", "A, B, C...", "primary, secondary, tertiary...", etc., but this does not limit the interpretation of the present invention in a narrow sense, and the order may be changed as desired. A combination product may be a combination item or a combination, or may be a set product, a set, or a kit product or a kit. [Explanation of symbols]
