In particular, the technical configuration and effects for preventing leakage of excrement, and for ensuring a comfortable fit by securely and easily pressing the faceplate against the abdomen around the stoma, differ significantly in their technical configuration and effects. Furthermore, the technical configuration and effects of the stoma appliance fixing belt for securing the stoma appliance also differ significantly from those in the prior art documents. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Registration No. 3236079 [Patent Document 2] Japanese Patent Publication No. 2013-240565 [Patent Document 3] Actual registration 3180697 [Patent Document 4] Actual registration 3152754 [Patent Document 5] Actual registration 3145805 [Patent Document 6] Japanese Patent Publication No. 08-229060 [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] In daily life using ostomy appliances, there are various consumables, and the replacement and replenishment of these consumables incur costs. These include ostomy pouches, skin protection films to protect the skin around the ostomy, skin protection powders, cleaning cleaners, alcohol-free wet wipes, and adhesive removers to reduce pain when removing the faceplate. We want to reduce the number and amount of these consumables used, or create ostomy appliances that do not require the use of some of them, in order to reduce the cost of necessary consumables. In this invention, the term "stoma appliance" refers to a specialized device for safely and securely collecting feces or urine excreted from a stoma, consisting of a faceplate, absorbent pad, a flexible plate-like object formed in a roughly rectangular shape, a stoma pouch, a belt for securing the stoma appliance, etc.

[0011] Furthermore, if waste leaks from the stoma into the stoma pouch, it can stain underwear, irritate the skin, and emit an unpleasant odor. Therefore, it is important to prevent any leakage from the stoma appliance.

[0012] In ostomy appliances where the faceplate is attached to the ostomy area with adhesive and then peeled off, the attachment may be incomplete. If it comes off during use, the ostomy appliance becomes unusable, causing significant problems. Therefore, instead of attaching the faceplate to the ostomy area with adhesive, we want to develop a different method of securing the faceplate to the ostomy area by lightly pressing it against the ostomy appliance with an ostomy appliance fixing belt, thereby ensuring the faceplate is securely fixed around the ostomy area. The faceplate is the part of the ostomy appliance that comes into direct contact with the abdominal skin around the ostomy.

[0013] Furthermore, when securing the faceplate, stoma pouch, and other stoma appliances with a belt that wraps around the abdomen, it is necessary to ensure that the stoma appliance is securely fastened to prevent leakage of waste. Therefore, the belt length should be easily and reliably adjustable to accommodate individual differences and changes in body shape, and because the stoma pouch is attached, making the work difficult, it should be possible to fasten it extremely easily with a single touch without visual inspection. Also, as mentioned above, because the work is difficult, it should be possible to remove it extremely easily with a single touch without visual inspection. [Means for solving the problem]

[0014] A faceplate is provided between the stoma and the stoma pouch. Furthermore, an absorbent pad having a hole in the center through which waste passes is sandwiched between the faceplate and the stoma pouch side. On the stoma pouch side of the absorbent pad, a horizontally elongated, roughly rectangular or elliptical plate-like body made of a flexible material having a hole in the center through which waste from the stoma passes is provided. The ends of a belt for securing the stoma appliance are fixed to both ends of the plate-like body in the horizontal direction, and the belt is wrapped around the abdomen of the person, so that the faceplate is lightly pressed against the area around the stoma via the absorbent pad to secure it. The term "horizontally elongated" refers to the direction around the abdomen, not the vertical direction of the human body. The aforementioned plate-like body is slightly larger than the faceplate and is used to lightly press the faceplate around the stoma. A stoma is an opening created in the abdomen during surgery for the excretion of feces or urine. The absorbent pad is a typical thin, porous structure, a few millimeters thick, with a high absorbency.

[0015] Silicone clay may be applied around the hole in the central part of the absorbent pad through which waste from the stoma passes.

[0016] The aforementioned stoma appliance fixing belt has a cam buckle type belt length fixing device for adjusting the length to fit the size of the person's abdomen, and a slip-on buckle type fixing device to form a loop and secure the belt around the abdomen. That would be good. [Effects of the Invention]

[0017] Rather than being attached to the abdomen around the stoma with an adhesive, the panel is a flexible plate-like body and is gently pressed against the abdominal skin surface around the stoma via a water-absorbing pad by stoma appliance fixing belts fixed to both ends in the length direction of the flexible plate-like body. Thus, it is firmly and reliably adhered and fixed to the abdomen around the stoma, and the panel will not come off from the abdominal skin surface around the stoma.

[0018] Also, the stoma appliance fixing belts are fixed at both ends in the length direction of the flexible plate-like body that can deform flexibly against external forces, that is, it is a plate-like body that conforms to the human body shape. Moreover, the panel conforms to the shape of the human body and is pressed against it with an increasingly flexible and light force without a strong force acting locally around the stoma, resulting in comfort and a higher degree of adhesion of the panel to the periphery of the stoma. This substantially eliminates the risk of excrement leaking from the gap between the panel and the abdominal skin around the stoma during its movement to the stoma pouch.

[0019] By using a horizontally long, roughly rectangular or elliptical flexible plate-like body, it well conforms to the abdominal shape of the person wearing the stoma appliance. Without a strong force being applied locally, not only is the panel naturally gently pressed against the abdomen, but also the panel is gently pressed against the abdomen via the water-absorbing pad. Due to the double cushioning effect of the flexible plate-like body and the water-absorbing pad, the panel is more softly pressed against the abdomen. There will be no gap for excrement to leak, and excrement will not leak.

[0020] Also, as described above, the panel is a flexible, roughly rectangular or elliptical plate-like body sandwiching the water-absorbing pad and is gently pressed against the periphery of the stoma with a belt. Without a locally unreasonable force being applied, it conforms to the abdominal shape and is gently pressed against the abdomen, thereby obtaining a comfortable wearing feeling.

[0021] Since a water-absorbing pad having a hole through which excrement passes is sandwiched between the face plate and the flexible plate-like body, even if there is a gap between the face plate and the flexible plate-like body, the excrement will be absorbed there and will not leak out, so the underwear will not be soiled, and the odor of the excrement will also be greatly reduced from leaking out.

[0022] If silicon clay is applied around the hole of the water-absorbing pad having the hole through which the excrement passes, leakage of excrement and leakage of odor can be further highly prevented. This is because silicon clay is a type of clay whose shape can be freely changed according to the shape of the gap, does not dry out or harden even when exposed to air, and is a material with high water-repellency and low water permeability. Furthermore, because it is made of silicon clay, it is not easily soiled by hands, and it is easy for people to apply the silicon clay.

[0023] If the stoma appliance fixing belt has a cam buckle type belt length fixing tool for adjusting the length and is made to be fixed around the abdomen in a circular shape with a plug-in buckle type fixing tool, the length of the belt can be easily and at low cost adjusted according to the size around the abdomen. Also, since it can be formed into a circular shape in one touch just by inserting the plug-in buckle type (side release buckle type) plug-in fixing tool (male side) into the plug-in fixing tool (female side), it is not easily visible, and the fixing work of the stoma pouch can be easily done even in a situation where it is difficult to attach the stoma pouch.

[0024] Also, since the belt can be fixed simply and surely with a plug-in buckle type fixing tool, if the belt comes off, it will have a serious adverse effect on the stoma, but the belt will not come off, and the complete stoma function can be exerted. Also, since the formation of the circular shape can be released just by pinching and pressing the release knob of the plug-in fixing tool with a finger, the release can be extremely easily done even in a situation where the work is difficult.

[0025] From the above, there is little need to use a skin protection film, skin protection powder, cleaner for washing, non-alcohol wet tissue, and adhesive remover for reducing pain when peeling off the face plate, and the cost of necessary consumables is greatly reduced. Furthermore, since there is no leakage of waste, the frequency of changing the stoma pouch decreases. This also contributes significantly to reducing the cost of consumables. [Brief explanation of the drawing]

[0026] [Figure 1] This is an explanatory diagram showing the ostomy appliance of the present invention as viewed from the front, towards the person wearing it. [Figure 2] This is an explanatory diagram of the stoma appliance of the present invention, viewed from the opposite direction to Figure 1, that is, from the back or reverse side. [Figure 3] This is an explanatory diagram of the stoma appliance of the present invention, viewed from the A-A cross-section, i.e., the side view, in Figure 2. [Figure 4] This is a schematic diagram illustrating a stoma appliance fixing belt with a substantially rectangular, flexible plate-like body for securing the stoma appliance of the present invention around the abdomen. Note that each figure is an explanatory diagram of one embodiment of the invention and is not represented to the same scale. [Modes for carrying out the invention]

[0027] The embodiments of this invention will be described below with reference to the drawings. It should be noted that the embodiments are not limited to these embodiments and can be modified as appropriate within the scope of the present invention. In other words, not only the embodiments shown in the drawings but also various other embodiments can be adopted within the scope of the present invention.

[0028] Figure 1 is an explanatory diagram of the stoma appliance of the present invention as viewed from the front of the human body. The end of the stoma pouch opening 14 of the stoma pouch 1, i.e., the stoma pouch opening end 13, is fixed between a horizontally elongated, approximately rectangular flexible plate-like body 2 and an absorbent pad 5. In this embodiment, a flat, circular faceplate 4 is lightly pressed against the abdominal skin 9 by a stoma appliance fixing belt 3 that is wrapped around the abdomen. In this embodiment, the flexible plate-like body 2 is a horizontally elongated, nearly rectangular shape that is larger than the faceplate, but it may also be, for example, a horizontally elongated ellipse, or a roughly horizontally elongated rectangle or ellipse. Furthermore, it may be any other horizontally elongated shape. In short, it is sufficient that it is larger than the faceplate 4 and that the faceplate 4 is lightly and comfortably pressed against the stoma 12 by the stoma appliance fixing belt 3.

[0029] The absorbent pad 5 can be made of, but is not limited to, porous nylon resin, superabsorbent polymer, or absorbent resin. Since the material of the absorbent pad 5 is generally porous, it has a cushioning effect against external forces. As a result, in this invention, the absorbent pad 5, in combination with the flexible plate-like body 2, allows the faceplate 4 to be pressed against the stoma 12 with a gentle force and light pressure, ensuring the comfort of the wearer.

[0030] Flexibility refers to the property of a material or structure to be able to deform flexibly in response to external forces and return to its original shape. Some plastics, which are polymer compounds, are also flexible; that is, they can be bent without breaking, change shape, and return to their original form. These can be used in the flexible plate-like body 2. Flexible materials include polymer-based materials such as silicone rubber, polyurethane, natural rubber, and nitrile rubber, and fiber-based materials such as nylon, polyester, and aramid fibers, but are not limited to these.

[0031] The waste contained in the stoma pouch 1 is opened and closed by a clamp (also called a clip) 6 and discharged to the outside of the stoma pouch 1 through the stoma pouch outlet 7. Stoma appliance securing belts 3 are attached to both lateral ends of the flexible plate-like body 2 for wrapping around and securing it to the abdomen. In this invention, a flexible plate-like object 2 and an absorbent pad 5 are sandwiched between the faceplate 4 and the stoma pouch 1, so the stoma pouch 1 is mainly a so-called two-piece type (two-part system type). Furthermore, the flexible plate-like material 2 may be cut with scissors or similar tools to adjust its dimensions to fit the shape of the user's body.

[0032] Figure 2 is an explanatory diagram showing the stoma appliance of the present invention as viewed from the back, that is, from the side that is in contact with the abdomen. The faceplate 4 has a faceplate stoma opening 8 through which waste products from the stoma 12, a new opening for stool or urine created in the abdomen by surgery, can pass. The faceplate stoma opening 8 is generally circular, but the shape of the opening may be changed by cutting the original circular opening to match the shape of the stoma 12 of the person using the stoma appliance. A roughly circular absorbent pad 5, having a central hole 10, is sandwiched between the faceplate 4 and, in this embodiment, a roughly rectangular, horizontally elongated flexible plate-like body 2. In this embodiment, silicone clay 11 is applied around the central hole 21 of the absorbent pad 5.

[0033] The absorbent pad 5 may be attached to the flexible plate-like body 2 with paper tape 18 or the like as needed. Although the number of attachment points is shown as two in Figure 2, it may be attached in more locations. Absorbent pad 5 can be made from materials such as superabsorbent resin, nylon, or polyester fibers, but is not limited to these materials.

[0034] Figure 3 is an explanatory diagram of the A-A section shown in Figure 2. The stoma opening 8 of the faceplate 4 communicates with the stoma 12 located in the abdominal skin 9. The faceplate stoma opening 8 can be a pre-made type with a predetermined hole size, or it can be a free-cut type that can be cut to fit the stoma 12, allowing the user to freely determine the size of the opening. In this embodiment, a roughly circular water-absorbing pad 5 is sandwiched between the faceplate 4 and the flexible plate-like body 2. Furthermore, silicone clay 11 is applied around the central hole 21 of the water-absorbing pad 5.

[0035] Silicone clay is a type of clay made from silicone material that does not dry out or harden. It is a highly water-repellent material that is resistant to water penetration. When used together with the absorbent pad 5, even if a gap forms between the faceplate 4 and the flexible plate-like body 2, leakage of excrement can be better prevented in the stoma appliance of this invention.

[0036] The stoma pouch 1 has its stoma pouch opening 14, with the circumferential end 13 of the stoma pouch opening sandwiched between the flexible plate-like body 2 and the absorbent pad 5. The circumferential end 13 of the stoma pouch opening is passed through the central hole 20 of the flexible plate-like body 2 and secured by being sandwiched around the outer circumference of the central hole 10 of the absorbent pad 5. In this embodiment, it is secured by being sandwiched between the flexible plate-like body 2 and the portion of the absorbent pad 5 coated with silicone clay 11.

[0037] In this embodiment, the circumferential end 13 of the stoma pouch hole 14 is sandwiched between the flexible plate-like body 2 and the silicone clay 11. The stoma pouch 1 is made of a multilayer structure using materials such as polyethylene, ethylene vinyl alcohol, and polypropylene to achieve a good balance of durability and flexibility, and the end 13 of the stoma pouch hole can be fixed by sandwiching it between the flexible plate-like body 2 and the absorbent pad 5 or the silicone clay 11.

[0038] The excrement passes through the stoma 12, the stoma hole 8 on the faceplate, the central hole 10 in the silicone clay, and the stoma pouch hole 14, and is collected in the stoma pouch 1 in the direction of arrow B. In embodiments where the silicone clay 11 is not applied, the portion of the silicone clay 11 also becomes part of the absorbent pad 5, and the excrement passes through the central hole 21 of the absorbent pad. In other words, in this case, the absorbent pad 5 also exists in place of the portion of the silicone clay 11. In this case, the central hole 21 of the absorbent pad extends to the position of the central hole 10 of the silicone clay. Even without the cam buckle type belt fastener 15

[0039] Figure 4 shows the stoma appliance fixing belt of the present invention, which is worn around the abdomen. The belt portion 3 of the stoma appliance fixing belt is fixed to both ends 3(A) in the longitudinal direction of a flexible plate-like body 2, which has a hole 20 in the center of a roughly rectangular flexible plate-like body. The belt portion 3 of the stoma appliance fixing belt is secured by wrapping it around the abdomen and inserting the insert buckle-type fixing device 16 (male side) into the hole on the other side (female side). In addition, there is a cam buckle-type belt length fixing device 15 for adjusting the length of the belt portion 3 of the stoma appliance fixing belt so that it can be adjusted to the waist circumference which varies from person to person. The cam buckle-type belt length fixing device 15 is a fixing part that keeps the belt length constant and prevents loosening and slippage. In this embodiment, it is a cam buckle-type (cam-type) belt length fixing device that clamps and fixes the belt.

[0040] Furthermore, the cam buckle type belt length fixing device 15 may be integrated with the belt pass-through hole 16(A) of the insert buckle type fixing device 16 (male side). Alternatively, a cam buckle type belt length fixing device may also be provided in the belt pass-through hole 17(A) of the insert buckle type fixing device (female side). In short, it is sufficient to have an insert buckle type fixing device (male side) and an insert buckle type fixing device (female side), with the cam buckle type belt length fixing device located in one of these places.

[0041] Figure 4 is a schematic diagram illustrating the above. For example, even without the cam buckle type belt length fixing device 15, it is sufficient if either or both of the belt pass-through holes 16(A) of the insert buckle type fixing device (male side) or the belt pass-through holes 17(A) of the insert buckle type fixing device (female side) have the function of a cam buckle type fixing device. Note that the thickness of the belt portion 3 is not shown in the figure.

[0042] Furthermore, the insert buckle type fastener is used in bags and work belts, where the male side 16 is inserted into the female side of the other side to secure it, and both release knobs 19 on both sides are pushed in opposite directions to release it. And as explained in the section on the effects of the invention, it is particularly effective as a stoma appliance fixing belt 3. A belt made from a strip of fabric woven by crossing warp and weft threads is also acceptable. The belt material can be polyester, nylon, rubber, resin, acrylic, leather, etc., but is not limited to these materials. [Industrial applicability]
