Description

[Technical Field]

[0001] The present invention relates to a plate for an ostomy pouch and an ostomy appliance. [Background technology]

[0002] In cases where a person has a disease of the digestive or urinary tract, or is unable to control their own excretion, a stoma (artificial anus, artificial bladder, etc.) may be created on the surface of the body by guiding the digestive tract or urinary tract to the body surface. Because users with a stoma (also known as ostomates) are unable to control their own excretion, a bag (stoma appliance) is attached to the opening of the stoma bag to temporarily store excreta from the stoma.

[0003] When an ostomate attaches a stoma appliance to the opening of a stoma bag, they may use an auxiliary belt or the like to improve the adhesion of the stoma appliance to the abdominal wall and to securely fix the stoma appliance in place. For example, Patent Document 1 discloses a stoma appliance that has one or more tabs for connecting the auxiliary belt to suit such an attachment style. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-34868 Summary of the Invention [Problem to be solved by the invention]

[0005] However, some ostomates do not use an auxiliary belt when attaching the stoma appliance to the opening of the stoma pouch. For these ostomates, the tab for fastening the auxiliary belt is unnecessary, and the tab may come into contact with the abdomen, causing discomfort or even skin damage.

[0006] Therefore, a main object of the present invention is to provide a plate for a stoma bag and a stoma appliance that can avoid pressure on the skin and discomfort. [Means for solving the problem]

[0007] In order to solve the above problem, one embodiment of the present invention is a plate for a stoma bag, which comprises a ring-shaped main body, a separation portion having a connecting region, and a cutting portion arranged between the outer edge of the main body and the separation portion. [Effects of the Invention]

[0008] According to the stoma appliance using the stoma bag plate of the present invention, pressure on the skin and discomfort can be avoided. The effects of the present invention are not limited to those described here, and may be any of the effects described in this specification. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the embodiments described below are examples of typical embodiments of the present invention, and do not limit the scope of the present invention, and various combinations, modifications, and changes are possible within the scope of the gist of the present invention.

[0011] (1) Stoma bag plate Fig. 1 is a plan view of an example of a configuration of a plate for a stoma bag according to the present invention, seen from the side that does not face the skin when attached to a human body. As shown in Fig. 1, a plate for a stoma bag 10 as an example of a configuration of the present invention comprises an annular main body 11, a separation part 13 having a connecting region 12, and a cutting part 14 arranged between the outer edge of the main body 11 and the separation part 13.

[0012] In the stoma bag plate according to the present invention, the main body is annular, so that waste and other materials excreted from the ostomate's stoma can be transmitted to the stoma appliance by passing through the ring.

[0013] In FIG. 1, the shape of the main body 11 is a circular ring, but it is not limited to a circular ring and can be a ring of any shape, such as an oval, that matches the shape of the stoma.

[0014] The stoma bag plate of the present invention can be connected to an auxiliary belt or the like in the connecting region 12, allowing the ostomate to use the auxiliary belt or the like to improve the adhesion of the stoma appliance to the abdominal wall and securely fix the stoma appliance.

[0015] In the stoma bag plate according to the present invention, the stoma appliance can be suitably fixed to the abdominal wall of the ostomate by the auxiliary belt because there are two or more connecting regions 12. The method of connecting the auxiliary belt and the stoma bag plate is not limited, and they can be connected by any method, such as a method in which a fastener provided on one of the auxiliary belt or the stoma bag plate is used to fasten the other, or a method in which a clip or the like provided on one of the auxiliary belt or the stoma bag plate is used to clamp the other.

[0016] Furthermore, in the stoma bag plate according to the present invention, at least two connecting regions 12 are required to be provided in order to secure the stoma bag plate 10 to the ostomate's stoma using an auxiliary belt, but by providing two or more, for example, the ostomate can connect the auxiliary belt to any connecting region and secure the stoma bag plate at any position.

[0017] In the stoma bag plate of the present invention, the arrangement and shape of the connecting area are not particularly limited as long as they are arrangement and shape that allow the stoma bag plate to be fixed to the ostomate's stoma using an auxiliary belt, and can be changed as appropriate to match the shape of the auxiliary belt and the shape of the stoma.

[0018] The stoma bag plate according to the present invention has one or more separators on the outer edge of the main body. As shown in Fig. 1, the stoma bag plate according to the present invention may have an annular separator 13 arranged annularly along the outer edge of the main body 11, but may also have two or more separators 13. For example, Fig. 2 shows an example of an stoma bag plate having two separators 13, but the positions of the two or more separators are not limited to the example shown in Fig. 2.

[0019] In the stoma pouch plate 10 shown in Fig. 2, by increasing the width B of the joint surface between the separation part 13 and the main body 11 along the outer edge of the main body 11, and more preferably by forming the separation part 13 into a ring shape along the outer edge of the main body 11 as shown in Fig. 1, the strength against the tensile force of the auxiliary belt when used by an ostomate is improved. This reduces the risk of the separation part 13 being separated from the main body 11 due to the tensile force of the auxiliary belt.

[0020] In the stoma bag plate of the present technology, in order to reduce the risk of the separation part (each separation part, if there are two or more separation parts, as in the example of the stoma bag plate shown in Figure 2 or Figure 12) being unintentionally detached from the main body, the separation part may be joined to the main body along the outer edge of the main body within a range of 10% or more, preferably 20% or more of the outer edge of the main body (the entire outer circumference of the main body).

[0021] On the other hand, from the viewpoint of reducing the discomfort felt by ostomates when wearing the stoma appliance, it is preferable to design the separation part to be small and narrow the area where it joins with the main body. From this viewpoint, the separation part may be joined to the main body along the outer edge of the main body over a range of less than 100% of the outer edge (entire circumference) of the main body, for example, 90% or less, 80% or less, 70% or less, etc.

[0022] Furthermore, in view of the above-mentioned viewpoints, the stoma bag plate of the present technology can design the joining area between the separation part and the main body to suit the ostomate who uses the stoma bag plate.

[0023] As described above, in order to reduce the risk of unintentional detachment from the main body, as shown in the examples of Figures 2 and 12, the length of the width B of the joint surface between the separation part 13 and the main body 11 measured in the diameter direction of the ring of the main body 11 (in Figure 12, the direction along the center line H of the ring of the main body 11, parallel to the line defining the width B) should be 10% or more of the diameter of the ring of the main body 11, preferably 25% or more, and more preferably 50% or more.

[0024] Furthermore, in order to reduce the discomfort felt by ostomates when wearing the stoma appliance, as shown in the examples of Figures 2 and 12, the length of the width B of the joint surface between separation part 13 and main body 11, measured in the direction of the diameter of the ring of main body 11, may be designed to be in the range of less than 100% of the diameter of the ring of main body 11, for example, in the range of 99% or less, 95% or less, etc.

[0025] The diameter of the ring of the main body 11 is determined by a center line H that is parallel to the line defining the width B, as shown in Fig. 12. For example, if the ring constituting the main body is elliptical, the reference diameter length will vary depending on the position where the separation part is provided, but the shape of the separation part of the stoma pouch plate can be designed based on the above criteria to suit the ostomate who will use the stoma pouch plate. The diameter of the ring of the main body 11 is determined in the same way in Fig. 2.

[0026] Similarly to the above, to reduce the risk of unintentional detachment from the main body, the angle F formed by one circumferential end of the separation portion 13 with respect to the center line E of the ring of the main body 11 passing through the opposing connecting regions 12 may be designed to be, for example, 30 degrees or more, 40 degrees or more, as shown in the example of Figure 12. In this case, the other end of the separation portion can be designed in the same way.

[0027] Furthermore, in order to reduce the discomfort felt by ostomates when wearing the stoma appliance, as shown in the example of Figure 12, the angle F formed by one circumferential end of the separation part 13 with respect to the center line E of the ring of the main body 11 passing through the opposing connecting regions may be designed to be less than 90 degrees, for example, 80 degrees or less, or 70 degrees or less.

[0028] When the plate for an ostomy bag according to the present invention has two or more separation sections, the shape of the separation section is not particularly limited as long as it has a shape that has a connecting region. For example, the examples shown in Fig. 2 and Fig. 12 can be used, but the shape is not limited to these.

[0029] When the stoma bag plate according to the present invention has two or more separation sections, one separation section may have multiple connecting regions. By having one separation section have multiple connecting regions, the auxiliary belt can be easily fixed in a position that suits the wearing state of the ostomate using the stoma bag plate, improving the operability and wearing comfort of the ostomate.

[0030] It can be seen that the stoma bag plate 10 shown in Fig. 12 has two separation sections 13, and each separation section 13 has three connecting regions 12. For example, when the stoma bag plate 10 shown in Fig. 12 is attached so that the center line E of the stoma bag plate 10 is approximately parallel to the ground when the ostomate is standing, the auxiliary belt is connected to the adjacent connecting region 12 above the connecting region 12 through which the center line E passes, in one separation section 13 of the stoma bag plate 10, and connected to the adjacent connecting region 12 below the connecting region 12 through which the center line E passes, in the other separation section 13, so that the auxiliary belt can be hung diagonally and fixed even when the stoma bag plate 10 is not tilted diagonally. In this way, by making the stoma bag plate have two or more separation sections 13 each having two or more connecting regions 12, the auxiliary belt can be connected to the connecting region at any position that suits the wearing condition of each ostomate, such as parallel or diagonal to the center line E, thereby improving the operability and wearing comfort for the ostomate.

[0031] 12, when there are two separation sections 13, each of which has three connecting regions 12, the connecting regions can be designed so that the angle G formed by adjacent connecting regions 12 above or below the center line E with respect to the center line E is any angle, such as 30 degrees or 40 degrees, depending on the usage pattern of the ostomate. In addition, the angle G formed by adjacent connecting regions 12 is preferably in the range of 20 to 90 degrees, in order to facilitate the positioning of the auxiliary belt, etc.

[0032] 12 shows an example of an ostomy pouch plate having a separation section 13 with three connecting regions 12, but the number of connecting regions in the separation section may be increased or decreased depending on the usage pattern of the ostomate. Even in this case, the angle G, which determines the position of the connecting regions in the separation section, can be designed as desired.

[0033] Furthermore, in the stoma bag plate according to the present invention, as in the example shown in Fig. 12, the thickness of the side of the separation part 13 where the auxiliary belt is connected in the part having the connecting region 12 (the hatched part in Fig. 12) may be made thicker than the thickness of the other parts. By doing so, it is possible to prevent the separation part 13 from breaking at that part due to external force from the auxiliary belt or bending due to body movement when the stoma bag plate is worn.

[0034] The separating section of the stoma bag plate according to the present invention may have two or more connecting regions 12, for example, as shown in Figure 1 or 2. The stoma bag plate according to the present invention can be designed by appropriately selecting the number and shape of the separating sections and the number and arrangement of the connecting regions.

[0035] In the stoma bag plate according to the present invention, as shown in Figure 1 or 2, the separation part 13 having the connecting region 12 is connected to the main body 11 via the cutting part 14, so that an ostomate who does not use an auxiliary belt can easily detach the separation part 13 having the connecting region 12. This makes it possible to avoid pressure on the skin or discomfort caused by the separation part 13 coming into contact with the abdomen.

[0036] By positioning the connecting region of the separation part, for example, 0.05 mm to 20 mm, preferably 0.1 mm to 15.0 mm, away from the cutting part, the stoma bag plate does not become larger than necessary, and the discomfort felt by the ostomate when wearing the stoma appliance can be avoided.

[0037] 1, when the annular separating portion 13 is provided annularly along the outer edge of the main body 11, the stoma bag plate according to the present invention preferably has one or more cutting start points 15 extending radially of the stoma bag plate from the outer edge of the cutting portion 14 toward the outer edge of the separating portion 13. By providing the cutting start points 15, it is possible to easily separate the separating portion 13 from the main body 11 while ensuring resistance to the tension applied to the stoma bag plate 10 from the auxiliary belt.

[0038] In particular, as shown in Fig. 10, when an ostomate uses an auxiliary belt to attach the stoma bag plate 10 to the human body, for example, by extending the cutting start point 15 in a direction that is not perpendicular to the direction in which the auxiliary belt 30 pulls the stoma bag plate 10, it is possible to prevent the tension applied to the stoma bag plate 10 from the auxiliary belt 30 from concentrating on the cutting start point 15. This makes it difficult for the separation part 13 to separate from the main body 11, and prevents unintentional damage to the stoma bag plate 10. Note that in the example shown in Fig. 10, a stoma bag is not shown in order to explain how the ostomate uses the auxiliary belt to attach the stoma bag plate 10 of the present technology to the human body.

[0039] The stoma bag plate of the present invention is not particularly limited as long as it is made of a resin that can be used for stoma bag plates, and can be suitably manufactured using resins such as polyethylene (PE), polypropylene (PP), and ethylene vinyl acetate (EVA).

[0040] Furthermore, by aligning the direction in which cutting starting point 15 extends or the cutting direction in the cutting portion with the direction in which the resin constituting stoma bag plate 10 is oriented, it may become easier to separate separation portion 13 from main body 11. The direction in which the resin is oriented can be adjusted by controlling the flow behavior of the resin when forming stoma bag plate 10 by injection molding or the like.

[0041] The plate for a stoma pouch of the present invention can be used as a plate for correcting wrinkles on the skin surface (a so-called "convex plate"), and can also be used as a mating plate for a two-piece stoma appliance described below. The mating plate can be provided on both the stoma pouch side and the base plate side, which is the component that comes into direct contact with the user's skin.

[0042] (2) Cutting section Figure 3 is a side cross-sectional view of stoma pouch plate 10 at cross section A shown in Figure 1. Separation section 13 is arranged via cutting section 14 provided on the outer edge of main body 11. In the stoma pouch plate according to the present invention, the shape of the cutting section is not particularly limited as long as it facilitates separation of the separation section and the main body at the cutting section. For example, by making cutting section 14 thinner than the outer edge of main body 11 and separation section 13 as shown in Figure 3, when an ostomate applies force by hand to separate separation section 13 and main body 11, the force is concentrated on cutting section 14, making it easier to separate separation section 13 and main body 11.

[0043] In the ostomy bag plate according to the present invention, the shape of the cutting portion 14 disposed between the outer edge of the main body and the separating portion 13 can be any shape, such as a straight line or a curved line. For example, as shown in Fig. 2A, the cutting portion 14 may be provided in a curved line on the surface where the separating portion 13 and the main body 11 meet, or the separating portion 13 may be provided in a curved line along the outer edge of the main body 11, as shown in Fig. 2B.

[0044] The thickness of the cutting portion 14 is improved when it is thinner than the outer edge of the main body 11 and the separation portion 13, but is not particularly limited as long as it does not interfere with molding such as injection molding. For example, a thickness of 0.1 mm to 5 mm, preferably 0.2 mm to 2.5 mm, allows for suitable injection molding and enables the ostomate to separate the separation portion 13 from the main body 11 without using a cutting tool such as scissors. The method for forming the cutting portion 14 is not limited to the method of forming it during injection molding as described above, but it may be formed by cutting in a later process, or may be formed using any method, such as forming it during molding using a 3D printer.

[0045] In the stoma bag plate according to the present invention, the thickness of the cut portion may not be uniform, and some portions may be thicker or thinner than other portions. For example, by making the thickness of the end portion of the cut portion (near the cut start point), which is more susceptible to external forces, thicker than the thickness of the other portions of the cut portion, it is possible to prevent unintended cracks from occurring in that portion or breakage of the separation portion when the plate is fixed with an auxiliary belt or when the plate is bent due to bodily movement.

[0046] For example, in the example of the stoma bag plate in Fig. 12, which has two separation sections 13, the thickness of the cutting section 14 near the four cutting start points 15 may be made thicker than the thickness of the other parts of the cutting section 14. Also, in the example of the stoma bag plate in Fig. 1, in which one separation section 13 is provided along the ring of the main body 11, the thickness near the cutting start point 15 may be made thicker than the thickness of the other cuttable cutting sections 14, etc. In this way, the range of the region (near the cutting start point) where the relative thickness is increased in the cutting section is not limited and can be designed arbitrarily. For example, it may be designed to be within a range of 3 mm from the cutting start point.

[0047] Furthermore, in the stoma bag plate according to the present invention, the resin constituting the cutting portion can be made of different resins at the end of the cutting portion (near the cutting start point) and the other parts of the cutting portion, thereby preventing unintended cracks and cutting of the separation portion. Specifically, a resin with a relatively higher breaking strength may be used at the end of the cutting portion (near the cutting start point) than at the other parts of the cutting portion.

[0048] The narrower the width of cutting portion 14, the more force can be concentrated on cutting portion 14 when an ostomate manually applies force to separate separation portion 13 and main body 11. For example, by designing the width to be in the range of 0 mm to 5.0 mm, preferably 0 mm to 3.0 mm, it is possible to effectively concentrate force on cutting portion 14, as described above.

[0049] Furthermore, the width of the cut portion 14 may not be uniform, and some portions may be wider or narrower than the other portions. For example, by making the width of the end portion of the cut portion (near the cut start point), which is more susceptible to external forces, wider than the other portions, it is possible to prevent unintended cracks from occurring in that portion or breakage of the separation portion when the device is fixed with the auxiliary belt or when the device is bent due to body movement.

[0050] 3, if the angle C formed between the cutting portion 14 and the end of the separation portion 13 that contacts the cutting portion 14 is greater than 90°, when a force is applied by hand to separate the separation portion 13 from the main body 11, an external force is concentrated at the interface between the cutting portion 14 and the end of the separation portion 13. This allows the separation portion 11 to be easily and efficiently separated from the annular portion 16.

[0051] In addition to the angle formed between the cutting portion 14 and the end of the separation portion 13 that contacts the cutting portion 14 being greater than 90°, the angle formed between the cutting portion 14 and the end of the outer edge of the main body 11 that contacts the cutting portion 14 may also be greater than 90°.

[0052] In Fig. 3, the cutting portion 14 of the ostomy pouch plate 10 of the present invention is formed thinner than the outer edge of the main body 11 and the surface opposite the skin side of the separation portion 13, but it may also be formed thinner than the outer edge of the main body 11 and the surface opposite the skin side of the separation portion 13 as shown in Fig. 4A, or it may be formed thinner than both the outer edge of the main body 11 and the surface opposite the skin side of the separation portion 13 as shown in Fig. 4B. In particular, the configuration shown in Fig. 4B can improve hand tearability. In the side cross-sectional view of the ostomy pouch plate shown in Fig. 3, the cross-sectional shape of the main body portion 11 is convex, but this is not limited to this and any shape can be used depending on the purpose.

[0053] (3) Weakened lines Figure 5 is an enlarged view of the periphery of the cutting portion of a modified example of the ostomy pouch plate of the present invention. In the ostomy pouch plate of the present invention, the cutting portion 14 may be configured so that its thickness is thinner than the outer edge of the main body 11 and the separation portion 13, as in the example shown in Figure 3 or Figure 4, or it may be configured so that a weakened line 17 is provided in the cutting portion 14, forming a perforated through portion 16, as shown in Figure 5. Furthermore, in addition to making the cutting portion 14 thinner than the outer edge of the main body 11 and the separation portion 13, the cutting portion 14 may also be provided with a weakened line 17, forming a perforated through portion 16. The provision of the weakened line 17 can make it easier to separate the separation portion 13 from the main body 11.

[0054] In the modified example of the ostomy bag plate of the present invention shown in Fig. 5, the wider the width (D in Fig. 5) of the penetrating portion 16 in the normal direction perpendicular to the tangent line of the cutting portion 14, the easier it is to tear by hand, making it easier to separate the separating portion 13 from the main body 11. For example, if the width of the penetrating portion 16 in the normal direction perpendicular to the tangent line of the cutting portion 14 is 0.2 mm or more, injection molding can be performed favorably. There is no particular upper limit to this width, but by making it 5.0 mm or less, for example, it is possible to prevent the ostomy bag plate from becoming larger than necessary and avoid the discomfort that an ostomate may feel when wearing the stoma appliance.

[0055] If the spacing (pitch) of the through parts 16 in the weakened lines 17 is increased, the strength against the tensile force of the auxiliary belt when the stoma bag plate 10 is attached to the human body using the auxiliary belt increases, and if the spacing (pitch) is decreased, the strength against the tensile force of the auxiliary belt decreases, making it easier to separate the separation part 13 from the main body 11. Taking these factors into consideration, when weakened lines are provided in the stoma bag plate of the present invention, the pitch can be adjusted to suit the material of the stoma bag plate and the expected needs of the ostomate.

[0056] 5, the cross-sectional shape of the weakened line 17 is such that one end of the penetrating portion 16 in the tangential direction of the cutting portion 14 is made into a sloped surface 18, so that when the separating portion 13 and the main body 11 are separated, the point of application of force moves efficiently along the weakened line 17, thereby reducing resistance when separating the separating portion 13 and the main body 11. The sloped surface 18 may be provided only at one end of the penetrating portion 16 in the tangential direction of the cutting portion 14, but it can also be provided at both ends.

[0057] In the modified example of the stoma bag plate of the present invention shown in Figure 5, the method for forming the weakened line 17 is not particularly limited. For example, the weakened line 17 can be formed when the stoma bag plate is molded by injection molding or the like, or it can be formed by post-processing after molding.

[0058] 6 is a schematic diagram showing how the separation part 13 is cut off from the stoma bag plate 10 according to one embodiment of the present invention. A user of the stoma bag plate 10 according to the present invention, such as an ostomate, cuts off the separation part 13 and the main body 11 from the cutting start point 15 along the cutting part 14.

[0059] 7 is a plan view of the stoma pouch plate 10 with the separation section completely separated, viewed from the side that does not face the skin. Ostomates who do not use an auxiliary belt can avoid pressure and discomfort on the skin around the abdomen caused by the separation section by completely separating the separation section having the connecting region.

[0060] (4) Stoma appliances Figure 8 is a schematic diagram of a stoma appliance 20 equipped with a plate for a stoma bag according to one embodiment of the present invention, viewed from the skin side, and Figure 9 is a schematic diagram of a stoma appliance 20 equipped with a plate for a stoma bag 10 according to one embodiment of the present invention, viewed from the side opposite the skin.

[0061] The stoma bag plate of the present invention can be suitably applied to both a one-piece appliance in which the stoma bag for storing waste from the stoma and the stoma bag plate are integrated, and a two-piece appliance in which the stoma bag and the stoma bag plate are separate.

[0062] In the case of a one-piece stoma appliance, the stoma bag plate can be connected to the opening of the stoma bag (the portion where the stoma opening of the ostomate is located) by known means, such as welding by heat sealing or bonding with an adhesive, etc. In the case of a two-piece stoma appliance, the stoma bag plate can be connected to the opening of the stoma bag by fitting or using an adhesive, etc.

[0063] The following description will be given using an example of a one-piece stoma appliance shown in Figs. 8 and 9, but the present invention is not limited to the one-piece appliance shown below.

[0064] As shown in Figures 8 and 9, the stoma appliance of this embodiment comprises a stoma bag 21 that stores waste material from the stoma, an outlet 22 that discharges the stored waste material from the stoma bag 21 to the outside, and an outlet path 23 that connects the stoma bag 21 and the outlet 22.

[0065] 8 and 9, the stoma appliance 20 according to this embodiment may have a first joining part 24 on the surface of the stoma bag 21 opposite the skin and a second joining part 25 on the surface of the discharge path 23 facing the skin. As a result, by rolling up the discharge outlet 22 along the discharge path 23 and joining the first joining part 24 and the second joining part 25, the discharge outlet 22 and the discharge path 23 can be placed in a compactly folded state on the side of the stoma bag 21 opposite the skin.

[0066] In this case, first joining portion 24 and second joining portion 25 may be formed by hook and loop fasteners. For example, first joining portion 24 and second joining portion 25 may be formed by a pair of loop and hook surfaces, which makes it possible to suitably maintain discharge outlet 22 in a rolled-up, compactly folded state along discharge path 23.

[0067] Stoma appliance 20 may also be configured to have a rigid tip plate 26 on at least one surface of discharge path 23. By providing tip plate 26 on at least one surface of discharge path 23, discharge outlet 22 can be folded while being fixed to the width of tip plate 26 when rolled up along discharge path 23. Furthermore, by providing rigid tip plate 26 on at least one surface of discharge path 23, it becomes easier to maintain discharge outlet 25 in an open state when excrement and the like from the stoma contained in stoma bag 21 is discharged to the outside.

[0068] The rigidity of the tip plate 26 is not particularly limited, but for example, if the tip plate 26 has a rigidity higher than that of the material forming the discharge path 23, the discharge port 22 can be suitably rolled up along the discharge path 23.

[0069] 8 and 9, the stoma appliance 20 according to this embodiment includes a stoma bag plate 10 as a convex plate on the skin-facing surface of a stoma bag 21. By including the stoma bag plate 10, wrinkles that occur on the skin surface can be corrected and the stoma appliance 20 can be suitably attached to the opening of the stoma bag. Note that although this embodiment shows an example in which the stoma bag plate according to the present invention is used as a convex plate, the stoma bag plate according to the present invention can also be used as a fitting plate used in a two-piece stoma appliance.

[0070] 8 and 9, the stoma appliance according to this embodiment may be provided with a base plate 27 on the side of the stoma pouch plate 10 that comes into contact with the skin. The stoma appliance 20 is adhered to the skin via the base plate 27. The base plate 27 is a member that comes into direct contact with the skin, and is made of a material that is more flexible than the stoma pouch plate 10. This reduces pressure on the skin caused by the stoma pouch plate 10, which requires a certain level of rigidity to correct wrinkles that occur on the skin surface, coming into direct contact with the skin.

[0071] Furthermore, by making the outer edge of the base plate 27 larger than the outer edge of the stoma pouch plate 10, it is possible to effectively reduce direct contact of the stoma pouch plate 10 with the skin. However, to make it easier to connect the auxiliary belt to the connecting region, a part of the outer edge of the separation part having the connecting region may extend outward beyond the outer edge of the base plate.

[0072] (5) Auxiliary belt 10 is a schematic diagram showing an example of attaching the stoma bag plate according to the present invention to the human body using an auxiliary belt. By connecting the auxiliary belt 30 to the connecting region 12 provided in the separating portion 13 of the stoma bag plate 10, the adhesion between the stoma bag plate 10 and the skin that constitutes the abdominal wall is improved, and the stoma bag plate 10 can be securely fixed.

[0073] The auxiliary belt is not particularly limited as long as it has a belt fastener that can be fastened to the connecting region, and an auxiliary belt of any shape can be used depending on the condition of the ostomate.

[0074] 11 is a schematic diagram showing an example of how the stoma pouch plate 10 with the detachable portion separated is attached to the human body without using the auxiliary belt. Separating the detachable portion 13 having the connecting region 12 from the main body 11 prevents pressure on the skin and discomfort caused by the detachable portion 13 coming into contact with the abdomen, improving the comfort of use for the ostomate.

[0075] The present technology can have the following configurations. (1) a ring-shaped body; a separation portion having a connecting region; a cutting portion disposed between an outer edge of the body and the separating portion; A plate for a stoma bag comprising: (2) The plate for an ostomy bag according to (1), which has one or more separation sections. (3) The plate for an ostomy bag according to (1) or (2), which comprises two or more separation sections each having two or more connecting regions. (4) A plate for an ostomy bag according to any one of (1) to (3), wherein the thickness of the cutting portion is thinner than the outer edge of the main body and the separating portion that are in contact with the cutting portion. (5) A plate for an ostomy bag according to any one of (1) to (4), wherein the thickness of the circumferential end of the cut portion is thicker than the thickness of the portion other than the end. (6) A plate for an ostomy bag according to any one of (1) to (5), wherein the angle formed between the cutting portion and the end of the separating portion that contacts the cutting portion is greater than 90°. (7) A plate for an ostomy bag according to any one of (1) to (6), wherein the separation portion is annular along the outer edge of the main body. (8) A plate for an ostomy bag as described in (7), which has one or more cutting starting points extending along the radial direction of the plate from the outer edge of the cutting portion toward the outer edge of the separation portion. (9) A plate described in any of (1) to (8) above; a stoma bag having an opening; A stoma appliance comprising: [Explanation of symbols]
