Description

[Technical Field]

[0001] The present invention relates to a plate for a stoma pouch and a stoma 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] Several proposals have been made so far regarding techniques for preventing a stoma appliance or a plate for a stoma pouch from coming off the opening of the stoma pouch due to the ostomate's bodily movements, such as bending of the abdominal wall, etc. For example, Patent Document 1 discloses a plate for a stoma pouch that has at least four grooves so that bending of the plate for a stoma pouch occurs in a desired area. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2012-508046 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the plate described in Patent Document 1 bends in a predetermined area and does not change its bending position in response to the body movements of the ostomate. Therefore, the main object of the present invention is to provide a plate for a stoma bag and a stoma appliance that can bend in response to the body movements of the ostomate, particularly when the abdominal wall bends. [Means for solving the problem]

[0006] In order to solve the above problems, one embodiment of the present invention, a plate for a stoma bag, is a panel connected to an opening provided at a predetermined position on the stoma bag, and comprises at least an opening hole and an annular portion formed to surround the opening hole, and the annular portion has a high rigidity portion and a low rigidity region that is more flexible than the high rigidity portion, extending circumferentially from the annular portion. [Effects of the Invention]

[0007] According to the stoma appliance using the stoma bag plate of the present invention, the stoma bag plate can bend to follow body movements, thereby reducing the repulsion between the skin and the adhesive surface of the stoma appliance that comes into contact with the skin, thereby reducing the likelihood of the stoma appliance peeling off from the skin. 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]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] 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.

[0010] (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. As shown in Fig. 1, a plate for a stoma bag 10 as an example of the configuration of the present invention comprises an opening 14 and an annular portion 11 formed so as to surround the opening 14. In the annular portion 11, a high-rigidity portion 16 and a low-rigidity region 17 that is more flexible than the high-rigidity portion 16 are provided, extending in the circumferential direction of the annular portion.

[0011] Here, "flex" refers to bending, and "flexible" refers to being easily bent. Furthermore, a "low rigidity region" refers to a range that is relatively more flexible than a high rigidity region. In other words, a low rigidity region is more flexible than a high rigidity region throughout the entire low rigidity region. Note that the flexibility of a low rigidity region relative to a high rigidity region is not constant, and may vary within the region.

[0012] Means for making the low rigidity region more flexible than the high rigidity region include, for example, making the thickness of the low rigidity region thinner than the thickness of the high rigidity region, or using a material for forming the low rigidity region that is less rigid than the material for forming the high rigidity region, but are not limited to these means.

[0013] In Figure 1, the shape of the annular portion 11 is circular, 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 ostomate's stoma.

[0014] The stoma bag plate 10 of the present invention can be manufactured using a resin that can be used for stoma bag plates. For example, polyethylene (PE), polypropylene (PP), ethylene vinyl acetate (EVA), etc. can be suitably used, but the resin is not limited to these.

[0015] 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 Fig. 1, the stoma bag plate 10 does not have a belt fastening hole for fastening an auxiliary belt, but the stoma bag plate 10 of the present invention may have a belt fastening hole if necessary.

[0016] The number of belt connecting holes provided on the stoma bag plate 10 for fixing the auxiliary belt needs to be two or more. Also, by providing multiple belt connecting holes along the outer edge of the stoma bag plate 10, the ostomate can fix the stoma bag plate 10 at any position using the auxiliary belt.

[0017] The method for manufacturing the stoma pouch plate 10 is not particularly limited as long as it is a method that can be used to manufacture a plate for a stoma pouch. For example, it can be suitably manufactured by a molding method such as injection molding.

[0018] (2) Low rigidity region Fig. 2 is a schematic diagram of an example of the configuration of a plate for an ostomy bag of the present invention, taken along a cross section cut by line X in Fig. 1, looking at annular portion 11 in the circumferential direction from the starting point of the arrow in Fig. 1. As shown in Fig. 2, a high-rigidity region 16 and a low-rigidity region 17 are provided extending in the circumferential direction of the annular portion on the surface of plate for an ostomy bag 10, which is an example of the configuration, that does not face the skin. High-rigidity region 16 is the thickest point of annular portion 11 relative to surface 13 on the side that does not face the skin. On the other hand, low-rigidity region 17 is more easily bent than high-rigidity region 16 by gently curving in a wave-like manner along the circumferential direction of annular portion 11 from the position of high-rigidity region 16, which is the thickest point.

[0019] Note that Figure 2 shows an example in which the thickness of the low-rigidity region is made thinner than the thickness of the high-rigidity region, giving it a concave curved shape, making the low-rigidity region more flexible than the high-rigidity region; however, this is not limited to this, and the low-rigidity region can also be made more flexible than the high-rigidity region by other means.

[0020] In the stoma bag plate according to this embodiment, the low-rigidity region 17 is gently curved in a wave-like manner along the circumferential direction of the annular portion 11, thereby gradually reducing the thickness of the low-rigidity region. Therefore, the bending position of the stoma bag plate is not limited, and even when an ostomate wearing the stoma bag plate bends their abdominal wall or performs other movements, the stoma bag plate can bend in accordance with the ostomate's body movements. This reduces the repulsion between the stoma bag plate and the skin at their contact surfaces, making it less likely that the stoma bag plate or stoma appliance will peel off from the skin.

[0021] In the ostomy bag plate of the present invention, the preferred angle formed by two diametric lines passing through the center of the opening and the circumferential end of the low-rigidity region varies depending on the number of low-rigidity regions, but can be adjusted, for example, within a range of 10 to 160 degrees. Furthermore, when a pair of high-rigidity regions and low-rigidity regions is provided, the angle can also be within a range of 100 to 160 degrees. When two pairs of high-rigidity regions and two pairs of low-rigidity regions are provided, the angle can also be within a range of 10 to 70 degrees.

[0022] In addition, setting the preferred angle between the two diametric lines passing through the center of the opening and the circumferential ends of the low-rigidity region wider makes it easier for the ostomate to bend the ostomy pouch plate in response to movements such as bending the abdominal wall. On the other hand, narrowing the preferred angle between the two diametric lines passing through the center of the opening and the circumferential ends of the low-rigidity region (increasing the range of the high-rigidity region) increases the flexibility of the angle at which the ostomy pouch is attached relative to the midline of the body. Ostomates may attach the ostomy pouch at an angle (e.g., approximately 10 to 45°) relative to the midline of the body to avoid discomfort caused by the ostomy pouch outlet overlapping with their thighs and interference with excretory operations. In light of the above, the ostomy pouch plate of the present invention can also adjust the range of the high-rigidity region and the low-rigidity region to any desired ratio to meet the needs of the ostomate.

[0023] Fig. 3A is a side cross-sectional view of the stoma bag plate 10 shown in Fig. 1 and Fig. 2 at a cut surface cut along line Y (where the high rigidity portion is located). The high rigidity portion 16 forms approximately the same plane as the surface 13 of the annular portion 11 on the side that does not face the skin. In the embodiment shown in Fig. 3A, the high rigidity portion 16 is the thickest in the circumferential direction of the annular portion 11, and therefore the stoma bag plate 10 is least likely to bend at the high rigidity portion 16.

[0024] 1 and 2, the thickness of the low-rigidity region 17 is thinnest relative to the surface 13 of the annular portion 11 that does not face the skin. In the embodiment shown in Fig. 3B, the low-rigidity region 17 gradually becomes thinner along the circumferential direction of the annular portion 11 toward the cut surface Z, and is thinnest at the cut surface Z. This allows the stoma pouch plate to bend in response to the body movements of the ostomate.

[0025] In the stoma bag plate according to this embodiment, the difference in height of the thinnest part of low rigidity region 17 relative to surface 13 of annular portion 11 on the side not facing the skin is not particularly limited, and can be adjusted, for example, to 99% or less, 95% or less, etc. of the height of the surface of annular portion 11 on the side not facing the skin. The lower limit range can be adjusted, for example, to 1% or less, 5% or less, etc. of the height of the surface of annular portion 11 on the side not facing the skin. Note that the greater the relative difference in height of the thinnest part of low rigidity region 17 relative to surface 13 of annular portion 11 on the side not facing the skin, the more likely it is that the flexibility of the stoma bag plate will be improved.

[0026] In the stoma bag plate according to this embodiment, the width of the low-rigidity region 17 in the circumferential direction of the annular portion 11 is not particularly limited, but the wider the width, the more the flexibility of the stoma bag plate 10 can be improved. For example, the width of the low-rigidity region 17 in the normal direction to the opening hole 14 can be adjusted to 0.1 mm or more, 1 mm or more, with an upper limit of 50 mm or less, 30 mm or less, etc., so that the stoma bag plate 10 can be bent suitably.

[0027] In the plate for stoma bags according to this embodiment, high rigidity areas 16 and low rigidity regions 17 may be formed by continuously repeating a curved shape consisting of concave and convex surfaces as shown in FIG. 2, but for example, as shown in the schematic diagram of the main body viewed from the cut surface side of a modified example of a plate for stoma bags in FIG. 4, the low rigidity regions 17 may be curved shapes formed over a certain range in which the relative height to the surface 13 of the annular portion 11 on the side not facing the skin is the same.

[0028] 4, when an area where the relative height of the annular portion 11 relative to the surface 13 on the side not facing the skin is the same is formed over a certain range, the stoma bag plate 10 becomes more flexible over the entire area. As a result, when an ostomate wearing the stoma bag plate performs an action such as bending the abdominal wall, the stoma bag plate bends accordingly.

[0029] The size of the area where the relative height of the annular portion 11 relative to the surface 13 on the side not facing the skin is the same is not particularly limited, but it can be, for example, an area that extends continuously over a range of approximately ±30° along the ring of the annular portion 11.

[0030] In the plate for an ostomy bag according to the present invention, high rigidity regions and low rigidity regions may be arranged alternately as shown in Fig. 1. Furthermore, as shown in Fig. 1, two or more pairs of high rigidity regions and two or more pairs of low rigidity regions may be provided.

[0031] When the ostomy pouch plate according to the present invention has two or more pairs of high-rigidity regions and two or more pairs of low-rigidity regions, a pair of the high-rigidity regions may be arranged opposite each other on a diametric line passing through the center of the opening. In this case, two diametric lines passing through the center of the opening are formed. In the embodiment of Fig. 1, a pair of high-rigidity regions 16 (four in total) are arranged opposite each other on line X and line Y, which are diametric lines passing through the center of the opening. In this case, four low-rigidity regions 17 are arranged between the high-rigidity regions 16 arranged on line X and line Y.

[0032] When a pair of the high-rigidity portions are arranged opposite each other on a diameter line passing through the center of the opening in the stoma bag plate according to the present invention, the two formed diameter lines passing through the center of the opening may be perpendicular to each other as shown in Fig. 1. In the case of the form shown in Fig. 1, by adjusting the attachment position of the stoma bag plate according to the present invention to the abdominal wall of the ostomate, it is possible to bend the stoma bag plate 10, avoiding the center of the opening 14 where the opening of the stoma bag is located, as the abdominal wall of the ostomate bends.

[0033] Here, "orthogonal" means that two straight lines intersect at a right angle, but is not limited to a perfect right angle, and also includes a case where two diametric lines intersect at a nearly right angle to the extent that the stoma bag plate can be bent while avoiding the center of the opening hole of the stoma bag plate of the present invention.

[0034] In the stoma pouch plate according to the present invention, when a pair of the high-rigidity portions are arranged opposite each other on a diametric line passing through the center of the opening, after the wearer wears the stoma pouch plate, one of the diametric lines may be positioned so that it is parallel to the horizontal plane of the wearer. Because the abdominal wall of the ostomate bends horizontally, positioning one of the diametric lines so that it is parallel to the horizontal plane of the wearer allows the stoma pouch plate to bend in the direction of the bending of the abdominal wall of the ostomate.

[0035] Here, "horizontal" refers to a direction perpendicular to the direction of gravity, but is not limited to a direction that intersects the direction of gravity at a perfect right angle, and also includes a direction that intersects the direction of gravity at a nearly right angle within the range in which bending of the ostomate's abdominal wall may occur.

[0036] Fig. 5 is a schematic diagram showing a state in which an ostomy bag plate 10 is bent, with a pair of high-rigidity regions 16 (four in total) arranged opposite each other on two diametric lines passing through the center of the opening. As shown in Fig. 5, two bending lines (bending lines L1 and L2 in Fig. 5) are formed in an area deviating from a straight line (straight line Y in Fig. 5) passing through the center of the opening 14 and the high-rigidity regions 16. Because the low-rigidity regions 17 can be curved concavely at bending lines L1 and L2 as shown in Fig. 5, the ostomy bag plate 10 can be bent to avoid being bent on a horizontal line passing through the ostomate's stoma.

[0037] (3) Stoma appliances FIG. 6 is a schematic diagram of a stoma appliance 20 having a plate for a stoma bag according to one embodiment of the present invention, viewed from the side facing the skin, and FIG. 7 is a schematic diagram of a stoma appliance 20 having a plate for a stoma bag according to one embodiment of the present invention, viewed from the side not facing the skin.

[0038] 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.

[0039] 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 detachably by fitting or using an adhesive, etc.

[0040] The following description will be given using the one-piece stoma appliance shown in Figs. 6 and 7, but the present invention is not limited to the one-piece appliance.

[0041] As shown in Figures 6 and 7, the stoma appliance according to the present invention comprises a stoma bag 21 for storing waste material from the stoma, an outlet 22 for discharging the stored waste material from the stoma bag 21 to the outside, and an outlet path 23 connecting the stoma bag 21 and the outlet 22.

[0042] 6 and 7, the stoma appliance 20 according to the present invention may have a first joining part 24 on the surface of the stoma bag 21 that does not face the skin, and a second joining part 25 on the surface of the discharge path 23 that faces the skin. In this way, 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 that does not face the skin.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 6 and 7, the stoma appliance according to the present invention includes a stoma appliance 20 that includes a stoma bag plate 10 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.

[0047] 6 and 7, the stoma appliance according to the present invention 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.

[0048] Furthermore, by making the outer edge of the face plate 27 larger than the outer edge of the plate 10 for a stoma bag, direct contact of the plate 10 for a stoma bag with the skin can be effectively reduced.

[0049] The present technology can have the following configurations. (1) A base plate connected to an opening provided at a predetermined position of the stoma bag, The device includes at least an opening and an annular portion formed to surround the opening, The plate for an ostomy bag has a high-rigidity region and a low-rigidity region that is more flexible than the high-rigidity region, which are provided in the annular portion and extend in the circumferential direction of the annular portion. (2) The plate for an ostomy bag according to (1), which is flexible over the entire low rigidity region. (3) The plate for an ostomy bag according to (1) or (2), wherein the low rigidity region has a curved shape.
