FIELD OF THE INVENTION The present invention relates to stoma appliances. More specifically, the present invention relates to a stoma orthosis used for an artificial anus and an artificial bladder.

[0002]

2. Description of the Related Art The basic structure of an orthopedic brace currently in use includes a housing that is adhered and fixed to the body on the side of the stoma, and a bag that is attached to this housing and stores excrement discharged from the body. It consists of a pouch. Various methods have been proposed and put into practical use for mounting and fixing the housing and the pouch, but the most popular method is the tapper wear type fitting method used for sealing the lid of the tapper container. is there. That is, as shown in FIGS. 10A and 10B, the concave portion 51 and the convex portion
It is a method of forcibly fitting 52 by using the elasticity of the material, and the recesses 51 and the protrusions 52 have hooking portions 53 and 54 for hooking in the pulling-out direction. It cannot be removed.

[0003]

However, although the above-mentioned conventional tapper wear method is the simplest to manufacture, it has the following drawbacks when viewed from the standpoint of the patient who uses it. That is, a large force is required for removal, and this force also peels off the skin fixing adhesive tape on the housing side. In addition, there is a problem that the position of the uneven portion is difficult to see at the time of attachment, and it is very difficult for an elderly person to fit it.

In view of the above circumstances, it is an object of the present invention to provide an ostomy appliance which can be attached with a light force and whose fitting position can be easily adjusted.

SUMMARY OF THE INVENTION The stoma appliance of the present invention stores a housing fixed around the stoma of a human body, a pouch base removably attached to the housing, and excrement attached to the pouch base. A pouch consisting of a bag for stoma, wherein the housing has a through hole for facing the stoma in the center, and the back surface is a flat adhesive surface for applying a skin protectant and a skin fixing adhesive. A ring-shaped flange portion formed, and a ring-shaped pedestal portion formed on the upper surface of the flange portion, at least in the lower half of the outer circumference between the flange portion and the pedestal portion, radially inward from the outer circumference And a ring-shaped groove for sealing, which is formed on the upper surface of the pedestal portion and has no hooking portion in the insertion / removal direction. The pouch substrate has a ring-shaped top surface formed with a through hole in the center and a surface on a flat adhesive surface for adhering a bag, and is formed in the back surface direction along the edge of the top surface. A cap member composed of a skirt, and an insertion piece projecting inward in the radial direction is formed in the lower half of the skirt, and is cut from the surface side at the boundary between the upper half and the lower half of the top surface. It is characterized in that it has a cut groove and an annular protrusion formed on the skirt and having no hooking portion in the inserting / pulling-out direction. In the present invention, it is preferable to provide an auxiliary lock for preventing the skirt of the pouch base from coming out of the pedestal portion of the housing when the pouch base is mounted on the housing.

[0006]

The present invention is characterized in that it is divided into a role of loading and unloading the pouch base on the housing and a role of sealing to prevent leakage of excretions in the mounted state. Therefore, the attachment / detachment part can have a structure that only pursues the ease of attachment / detachment without considering the hermeticity, and the sealing part has a structure that only pursues the hermeticity without considering the function of the attachment / detachment. We were able to. That is, the attachment / detachment is performed by inserting the insert piece of the pouch base into the insert groove of the housing and then pushing the upper half of the skirt to the outer circumference of the ring portion. To insert the pouch board, bend the upper half of the pouch base outward from the cut groove and pull the lower half upward while guiding the lower half along the flange surface of the housing.The half arc shape of the insert piece becomes the half arc shape of the insert groove. Being guided, the insertion piece can be securely fitted into the insertion groove even in a rough pulling operation. Therefore, there is no ergonomic burden on the operation of pulling up from the bottom without struggling with the alignment of the insert piece and the insert groove, and it can be easily performed even for an elderly person who is not physically fit. Next, the pushing operation is performed. This is an operation of pushing the upper half of the skirt into the outer periphery of the ring portion, and this operation can be performed only by pushing the pouch base to the human body side, which is very simple. Further, the removal may be carried out in the reverse order of the above. Therefore, the attachment / detachment of the stoma orthosis of the present invention is simple and easy, and can be attached / detached with a light force, and since the upper half of the skirt can be removed while pressing the pouch base, the skin fixing adhesive tape of the housing is not peeled off. Next, the sealing is performed by fitting the annular groove on the housing side with the annular protrusion of the pouch base. Since it is not necessary to consider disengagement prevention at the time of mounting the concave groove and the raised portion, it has a shape without any hooking portion in the inserting / pulling-out direction, and a great force is not necessary for the inserting / pulling-out. And
Since the shape of the contact is only required to prevent the leakage of excrement, the adhesion can be improved. The fitting of the concave groove and the protrusion is simultaneously performed by the operation of fitting the cap portion on the outer circumference of the ring portion.
