Ostomy appliance

Abstract

To solve the problems that an operation of injecting a chemical agent such as a deodorant or a lubricant from a discharge port in a lower portion of a pouch bag during wearing of a pouch which is an ostomy appliance has problems such as 1) the residual excrement may adhere to a hand and is unsanitary, 2) it takes a long time to diffuse the chemical agent in the entire pouch bag due to obstruction by the excrement remaining inside, and 3) the injected chemical agent is precipitated in the lower portion of the pouch bag together with the excrement and cannot surround the entire excrement, and a deodorizing function, a lubricating function, and the like of the chemical agent are limited; in addition, in the current system in which a certain amount of the medicine is injected into the pouch bag in advance, the medicine accumulated in the pouch bag flows out together at the time of degassing, which is uneconomical.SOLUTION: In the present invention, an openable and closable injection port is provided separately from the discharge port of the pouch bag for injecting the medicine or the like from the outside, so that the medicine can be injected at the time of discharge processing, thereby solving the above problems.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a pouch of a stoma appliance worn by a person with a digestive tract or urinary tract stoma, etc.

Background Art

[0002] A pouch, which is a stoma appliance worn by a person with a digestive tract or urinary tract stoma (hereinafter referred to as an "ostomate"), is an appliance for temporarily storing excreta (feces, urine, gas) from the anus. Its main components are a pouch bag (1) for storing excreta and a faceplate (2) for adhering the pouch bag to the abdominal wall around the stoma.

[0003] There are two types of pouches: a one-piece type pouch in which the pouch bag and the faceplate are pre-integrated, and a two-piece type pouch in which there is a joining tool between the pouch bag and the faceplate, and they are joined during use, and only the bag can be replaced while the faceplate remains attached to the abdomen.

[0004] Most of the pouch bags (1) have a multi-layer film structure with high airtightness by laminating in recent years to prevent leakage of excreta, moisture, and odor, and there are also pouches having a degassing port (3) for releasing gas discharged from the anus to the outside.

[0005] There are two types of pouch bags: a pouch with a discharge port (Figure 3) that can discharge the accumulated excreta many times during its wearing period, and a closed-type pouch (Figure 4) that has no discharge port and is discarded together with the bag when the excreta accumulates, and each is used among ostomates.

[0006] There are two ways to close the discharge port (4): 1) a method of winding up the lower part of the pouch bag several times and closing it with a clip, and 2) a method of adhering by firmly pressing two types of hook-and-loop fasteners (6a, 6b) respectively attached to the vicinity of the discharge port and the position where the discharge port is wound up with fingers. In recent years, the latter type of pouch using hook-and-loop fasteners has become the mainstream.

[0007] For the excrement discharge operation, after opening the discharge port (4), squeeze the pouch bag several times with fingers from top to bottom. Immediately after the discharge operation, the pouch bag, with excrement, gas, and air being extruded, will have its front and back surfaces stuck together.

[0008] In addition to the excrement discharge function, the discharge port also serves as an injection port for injecting deodorants and lubricants (hereinafter referred to as chemicals) into the pouch bag from the outside.

[0009] The deodorant is used for the purpose of reducing the odor during the treatment of excrement or the odor leaking from the degassing port (3). The lubricant is used to prevent excrement from sticking inside the pouch, and it is widely used for the purpose of preventing inflammations caused by excrement sticking to the stoma and reducing the discharge operation.

[0010] When using these chemicals, at the time of replacing the pouch with a new one, inject through the stoma hole (2a) pre-opened on the faceplate. Also, for re-injection during the pouch wearing (in the case of a pouch with a discharge port), after the excrement discharge treatment, inject into the pouch bag through the discharge port (4) for use. The usage amount of these chemicals for one injection is about 8 cc to 10 cc.

Summary of the Invention

Problems to be Solved by the Invention

[0011] 1. When injecting chemicals such as deodorants and lubricants into the pouch bag from the discharge port located at the lower part of the pouch bag during pouch wearing, the operation is blocked by the excrement remaining inside the pouch bag, and in the state where the front and back surfaces of the pouch bag are stuck together after the discharge operation treatment, it is difficult to spread throughout the entire pouch bag (especially the upper part and the periphery of the stoma), and it takes a long time until the injection operation is completed.

[0012] 2. When injecting the drug from the discharge port at the bottom of the pouch, even if it has finished diffusing to the upper part of the pouch bag over time, during the free fall of the drug or the sedimentation of excrement at the bottom over time, the drug accumulates at the bottom and cannot surround the entire excrement, and the deodorizing function and lubricating function of the drug cannot be fully exerted.

[0013] 3. Since it is necessary to open the discharge port where excrement remains for operation, it is unhygienic such as excrement adhering to the hands, and the psychological discomfort is also great.

[0014] 4. The current method of using the drug is to inject a certain amount into the pouch bag in advance. For the purpose of venting the gas accumulated in the pouch bag, when the discharge port is opened, the drug sedimented at the bottom flows out together, resulting in uneconomy.

Means for Solving the Problems

[0015] As a help for the ostomate to live more comfortably while maintaining the stoma in daily life, there are deodorants and lubricants for the pouch. However, the reinjection of these drugs during pouch wearing has no other way than injection from the discharge port located at the bottom of the pouch bag, and many problems such as the above-mentioned inconvenience, inefficiency, and uneconomy have occurred. The present invention has found that it can be solved by providing an openable and closable inlet (5) in addition to the discharge port in the pouch bag (1) (Figs. 1 and 2).

Effects of the Invention

[0016] 1. By attaching an inlet (5) different from the discharge port (4) to the pouch bag (1), when reinjecting drugs, etc., it is possible to inject the drug in a hygienic and clean manner different from the discharge port and without being blocked by the excrement when injecting the drug.

[0017] 2. By attaching the inlet (5) to the upper part of the pouch bag, the drug, etc. flows down from top to bottom and diffuses so as to wrap the surface of the excrement, so that the utility and effect of the drug are fully exerted. It is particularly effective in preventing sticking around the stoma.

[0018] 3. Compared with the prior injection of a certain amount (about 8 cc to 10 cc) which is the current drug usage method, after checking the amount of excrement, it is possible to inject from the upper part even immediately before excretion, the injection of an appropriate amount can be controlled, and there is no waste of the drug used. It is also possible to prevent the drug from leaking out during the conventional gas venting.

[0019] 4. Secondary effect: While the conventional degassing port (3) is not good at degassing in a short time (see Detailed Explanation A), by using this injection port (5) for degassing purposes, it is possible to quickly and easily degas the pouch bag without worrying about the leakage of excrement accumulated at the bottom (there is no need to go to the toilet for degassing).

[0020] Detailed Explanation A: When the degassing in the pouch bag is excessive, the conventional degassing port may cause the adhesion between the stoma and the inner surface of the pouch, which may hinder excretion. Therefore, when a certain amount of internal pressure is applied, the degassing function works slowly. Moreover, the degassing effect may be significantly deteriorated due to the adhesion of excrement, and few ostomates can feel the degassing function (in our company's survey, it is stated that more than 70% of ostomates cannot feel the function). When gas accumulates in the pouch other than at bedtime, it is common to open the discharge port in the toilet to release the gas.

Embodiments for Carrying Out the Invention

[0022] To solve the above problems, the following means are adopted. 1. As shown in Fig. 1, separately from the discharge port (4), a closable injection port (5) is provided. The structure of the injection port (5) may be the same as that of the discharge port (4). If the winding-up method is adopted, it can be stored in a folded state except during injection. The winding-up method means folding downward from the tip of the injection port (5) and adhering the surface fastener (7a) to the other surface fastener (7b). 2. As shown in Fig. 2, by attaching the injection port (5) to the closed-type pouch, it becomes possible to inject the drug even during wearing with the closed-type pouch. 3. As another injection port structure, as shown in Fig. 5, a method of screwing a screw-type screw cap (8) into the injection port (5) is also conceivable. With this method, the injection port (5) can be easily opened and closed with one hand.

[0023] Examples have been given and described regarding the present invention, but the technical scope of the present invention is not limited to the above-described scope. It is obvious to those skilled in the art that various changes or improvements can be made to the above examples. It is clear from the description of the claims that forms with such changes or improvements can also be included in the technical scope of the present invention.
