Abstract

PROBLEM TO BE SOLVED: To solve problems of conventional artificial anus apparatuses wherein most of them are apt to leak and uncomfortable to be installed and whose throwaway excretory substance storage bag is basically a dedicated article, an economically great burden for a user and impossible to use an available bag in emergencies. SOLUTION: This single flow type artificial anus apparatus comprises a first member directly applied to the skin around a stoma, a second member covering over the first member via a mouth part of the excretory substance storage bag, and a support belt being wound around the body for covering, press-fitting, and fixing them after installing them in a prescribed position. The both of the first member and the second member are truncated cone-shaped ring discs having holes in the centers and projecting in the hole parts. The first member is made of a silicone rubber and has a rigidity smaller than that of the second member. The support belt has an opening smaller than the external shape of the second member and larger than the hole in its prescribed position.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of an ostomy appliance. 2. Description of the Related Art When the anus temporarily or permanently does not function as an excretory port for some reason, a part of the colon (or ileum) is taken out of the body by surgery and used as an excretory port. It is an artificial anus. Stoma with artificial bladder
In some cases, the colostomy is referred to as the “gut stoma” and the artificial bladder is referred to as the “urinary stoma”. It is often made permanently due to rectal cancer or anal chain, and temporarily made when the anus is not used due to inflammation or the like. In the form of colostomy, there are a double-flow colostomy that takes the intestine out of the body in a looped state and cuts it out to make it a two-hole type, and a single-flow colostomy that only exposes the downstream end of the intestinal tract to the body. There are two types,
In the case of a temporary one, a double-flow type is used, and in the case of a permanent one, a single-flow type is often used. [0003] As described above, the colostomy substitutes the open end of the intestinal tract as an anus. However, since it does not have a sphincter, it is impossible to control defecation or keep gas out of its own will. Therefore, it is necessary to attach a bag (pouch) for storing stool and gas to the colostomy as a substitute for the rectum and manage it. This is the ostomy appliance. There are various types of orthoses depending on the form of the colostomy, skin condition, lifestyle, and the like. Depending on whether the bag (pouch) for storing excrement and the face plate provided with the skin protective agent are integrated or separated, they can be roughly classified into two types, one-piece type and two-piece type. The one-piece type has a feature that the face plate is rich in flexibility, so it is easy to handle because it is easy to adapt to the skin and only needs to be attached directly to the artificial anus, and the two-piece type has a pouch with the face plate attached. Only 1 to
It is exchanged about once every two days and can be degassed only by removing a part of the joint between the face plate and the pouch, and it can be bathed by replacing it with a special bathing cap. There is. [0005] Surgical methods and post-operative processing,
There are various problems with the colostomy, although it is gradually improved by the improvement of the brace. For example, problems such as swelling and smell of the surrounding skin are often serious, and there are many cases where hesitation to go out has been hindered in social life. In addition, the daily life of the wearer (except for temporary stomas) is indispensable for the life of the wearer, which is economically burdensome. For example, a pouch for storing excrement is one of the causes of economic distress because it is a consumable, but there are various forms to match the stoma shape, so it is not possible to substitute an inexpensive bag . In addition, some products may be washed and reusable, but in practice the strong odor is not easily reduced and can be washed at most once or twice. In addition, conventional ostomy appliances have a member called a "face plate", which is provided with an adhesive layer on one side, so that it is almost impossible to wash and reuse it, and the running cost is considerable. Become. [0006] Also, there are many equipments that are cumbersome to mount, which is not preferable. Further, the use of the orthosis is started immediately after the operation. However, since the stoma changes greatly for at least about 6 months, it is necessary to frequently change the orthosis if a severely sized orthosis is adopted. [0007] In view of the above points, the present inventor has finally completed a colostomy device according to the present invention as a result of intensive research and the features thereof are as follows.
A first member directly applied to the skin around the stoma, a second member put on the first member through the mouth portion of the excrement storage bag, and a cover for pressing and fixing them after setting them at a predetermined site A support belt for wrapping around the fuselage
Wherein the first member and the second member are each a frustoconical ring-shaped disc having a hole in the center and the hole portion rising. There, and the first member is made of silicone rubber and has a lower hardness than the second member, and the support belt is provided at a predetermined position thereof.
It has an opening smaller than the outer shape of the second member and larger than the hole. That is, according to the present invention, the opening of the excrement storage bag (conventional pouch or its substitute) is inserted between two perforated members having different hardnesses, and the whole is pressed and fixed by a support belt. It is a brace. Since the hardness is different, it is deformed by the pressing force, and does not shift or leak. The member having the smaller hardness (that is, the softer member) is the side that comes into direct contact with the skin, and since it is made of silicone rubber, it is less likely to cause inflammation and has good affinity with the skin. The stoma to which the orthosis of the present invention is applied is as follows:
Any one of a temporary one and a permanent one may be used, but the effect is remarkable on a permanent one. The orthosis of the present invention is limited to a “single-flow type colostomy appliance”. The "first member" is a member that comes into direct contact with the skin, and is for holding and fixing the excrement storage bag between the second member described below and the first member. It is made of silicone rubber formed as softly as possible without impairing the supporting force, and its structure is a frusto-conical ring-shaped disc having a hole in the center and the hole portion rising. This height is preferably about 10 to 20 mm in consideration of the feeling that it is noticeable if the thickness is too thick, so that the height is easily noticed from the top of the clothes, but it is not limited to the present invention. Also, "second member"
Although there is no significant difference in shape and size from the first member, they differ in that they are harder than the first member and that the material is not limited to silicone rubber. The "excrement storage bag" is a bag for storing stool and gas discharged from the intestinal tract, and is similar to a conventional pouch. However, while the conventional pouch was a special product attached to the brace, in the case of the present invention, the versatility is remarkably high, and the type is hardly selected unless the size of the opening is too small. Has features. Therefore, for example, a commercially available plastic bag can be used as it is. The "support belt" is a belt wound around the body to fix the excrement storage bag with the first member and the second member at a predetermined position. Since it is obtained by the support belt, it is preferable that a device for that purpose is elaborated, but the present invention does not limit the device itself. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the drawings. FIG. 1 shows an orthosis device 1 according to the present invention.
FIG. 2 is an exploded perspective view showing an example (hereinafter referred to as the present invention brace 1), and as is apparent from the figure, the brace 1 of the present invention has a first member 2 and a second member 3 which are discs having a truncated cone shape; It is constituted by the excrement storage bag 4 and the support belt 5 between which an opening is sandwiched. In this embodiment, the first member 2 and the second member 3 are both made of silicone rubber, and the center portion has a hole 2.
1, 31 are provided. However, these are not the same, and the hardness of the first member 2 is smaller than the hardness of the second member 3, and when a pressing force is applied in a state where these are stacked, the deformation amount of the first member 2 increases. Designed to. Since the excrement storage bag 4 stores stool and gas for about one to two days, it must be provided with tensile strength, tear strength, and air-proofing properties in accordance with the same. Since the shape of the bag, particularly the shape of the opening of the bag, does not need to exactly match the shape of the stoma, for example, a commercially available food sealed bag can be used. Of course, as the material, it is desirable that various properties such as polyester and polycarbonate are suitable for the present invention.
In the present invention, it is also possible to use a commercially available plastic bag (usually made of polyethylene) as an urgent use form. The one shown is such a commercially available plastic bag. The support belt 5 of this embodiment has a length of about 100 cm,
Although it is a fabric belt having a maximum width of about 10 cm, it is preferable to prepare several sizes depending on the body type of the wearer. As for the material, some elasticity is allowed, but it is not preferable that the pressing force against the first member 2 or the second member 3 cannot be maintained. The end of the support belt 5 around the body is locked by the hook-and-loop fastener 51. The hook-and-loop fastener 51 is a so-called male hook-and-loop fastener, and the material of the support belt 5 is employed so that it can be locked at any position on the surface of the support belt 5 main body. When the support belt 5 is attached in this manner, a pressing force is applied to another member, and as shown in FIG.
The airtightness of the excrement storage bag 5 located between the excrement storage bag 5 and the second member 3 becomes very high, and a structure in which stool and gas do not easily leak is obtained. A notch 52 and a sub-belt 53 are provided in the middle of the support belt 5. The sub-belt 53 is fixed by applying a tensile force after fixing the main body to the body by locking the hook-and-loop fastener 51.
Due to the presence of the notch 52 and the sub-belt 53, the operation of mounting the orthosis 1 of the present invention becomes very simple even without an assistant. That is, the support belt 5 is first attached so that the cutout 52 is located at the stoma site, and the first member 2 and the second member 3 that sandwich the excrement storage bag 5 are collectively fitted into the cutout 52. It is arranged at an appropriate position.
In the mounted state, the vicinity of the opening of the excrement storage bag 4 must be dived inside the support belt 5, but other portions need to be exposed outside the support belt 5. Therefore, FIG.
As shown in (b), the excrement storage bag 5, the first member 2, and the second member 3, which are put together in a state where the sub-belt 53 is removed, are fitted so that the main body portion of the bag comes out. If it is fixed, it can be easily installed. Note that the sub-belt 5 is
Fixing 3 makes it possible to adjust the pressing force after the main body is mounted, in addition to being easy to mount, and it is possible to replace the excrement storage bag 5 with the main body mounted.
Such a secondary effect is also preferable. As described above in detail, the ostomy appliance according to the present invention comprises the first member directly applied to the skin around the stoma and the first member via the mouth portion of the excrement storage bag. A single-piece colostomy appliance comprising: a second member to be covered by, and a support belt for winding them around the body to press and fix them after setting them at a predetermined site, Each of the first member and the second member is a frustoconical ring-shaped disk having a hole in the center and the hole portion is raised, and the first member is made of silicone rubber and has a hardness of the second member. The support belt is smaller than the two members, and the support belt has an opening at a predetermined position thereof, which is smaller than the outer shape of the second member and larger than the hole thereof, which will be described below. Extreme with various effects such as It is an advanced invention. (1) There is no need to use metal or hard plastic, and the member that contacts the stomal site is made of soft silicone rubber. (2) Since the structure is such that the opening of the excrement storage bag is sandwiched between two discs, this bag does not need to be a dedicated product, and a bag around us can be used in an emergency. (3) The hardness of the two discs is different, and the disc (first member) on one side (the side that comes into contact with the skin) is easily deformed when a pressing force is applied. And the adhesion between these members is increased, and leakage and displacement are almost eliminated.
