Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a prosthetic device that is attached to a stoma portion formed on the surface of a human body and accommodates discharge from the human body.
[0002]
[Prior art]
An ostomy device for accommodating feces excreted from the body is attached to a stoma portion that is surgically operated for rectal disease and the intestinal tract is guided to the body surface and constructed on the surface of the human body. Numerous proposals have been made for this colostomy device. Particularly, the abdominal patch member, the bag member and the like have been variously improved, the skin irritation, odor and stool leakage have been remarkably reduced, and the wearing feeling has been improved.
[0003]
However, for colostomys (ostomates), the treatment of effluent, or stool, can be done by either removing the colostomy device bag from the body or removing it from the body and scavenging the effluent and washing the inside of the bag. Although it is carried out, the discharge and cleaning of the discharge is a troublesome work, and the discharge is easy to get on the hand, and the sense of filth is high. In addition, the bag may be damaged during these operations, causing fecal leakage.
[0004]
There is a method of replacing the bag as a method of avoiding the discharge of the discharged matter and the cleaning of the bag, but in the so-called one-piece type in which the bag is integrally formed with the attaching member to the body surface of the ostomy device, In addition to complication of operation due to frequent re-sticking, there is a great risk of skin irritation due to adhesive stimulation. In the so-called two-piece type in which the sticking member and the bag are connected by fitting, there is no disadvantage as in the one-piece type, but the waste adhering to the vicinity of the fitting part is easily removed when the bag is replaced. In some cases, the fitting function may be impaired due to sticking to the fitting portion, and cleaning is often required. In both types, when going out for a long time, a suitable number of devices must be carried as spares and exchanged on the go.
[0005]
[Problems to be solved by the invention]
The object of the present invention is to clean and easily perform the treatment after containing the waste, and to minimize the number of parts to be discarded as waste, and to make the final treatment of the discarded parts simple and dust pollution. It is to provide a colostomy device that does not become a problem.
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, in the present invention, the skin part having an opening corresponding to the stoma part and the non-skin side of the skin part are detachably connected to each other, and the opening of the skin part is opened from the stoma part. through a plurality of bag body for accommodating the effluent is discharged, together with the plurality of bag is formed multi telescopically, each bag has an open end having one open end, the open It is equipped with a sealing mechanism at the end, and the used innermost bag body containing the discharged material is sequentially removed from the skin contact portion from the inside, and the innermost bag body can be sequentially pulled out through the open end of the outer bag body. It has become.
[0007]
Further, in the present invention, the nested bag body is covered with another bag body, and this other bag body is detachable from the first flange fixed to the non-skin side of the skin contact portion. The second flange has an opening corresponding to the opening of the skinned portion, and the second flange has an opening corresponding to the opening of the first flange. It may be.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Each bag can be connected to the skin contact portion or the non-skin contact side of the second flange by adhesion, welding, or fitting.
[0009]
Each bag body is open at one end, and the inner bag body can be pulled out through the open end. Moreover, this open end is provided with a sealing mechanism so that the bag body which is intended to accommodate the discharged material can be sealed.
[0010]
Each bag is preferably made of a degradable material. However, when the deodorizing material has a low deodorizing property, at least the outermost bag is preferably made of a highly deodorizing material.
[0011]
Materials constituting the bag include polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), polypropylene (PP), ethylene-methyl acrylate copolymer (EMA), ethylene-ethyl acrylate copolymer (EEA), ethylene- It is possible to use water-degradable materials such as methyl methacrylate copolymer (EMMA) and other materials, polyvinyl alcohol (PVA), biodegradable materials (such as microorganisms, chemical synthesis systems, and natural product utilization systems). it can. These materials are preferable in that they are easy to dispose of after disposal and do not cause waste pollution. When there is a problem in terms of the deodorizing property, it can be solved by using polyvinylidene chloride (PVDC) having a high deodorizing property which has been conventionally used for the outermost bag body. Further, for example, ethylene-vinyl alcohol copolymer (EVOH) is an environmentally preferable material. However, since the gas barrier property is extremely lowered under high humidity, there is a possibility that odor leakage may occur when it comes into contact with water-containing effluent. However, in the present invention, if this is used for the outermost bag body, it can be advantageously used because moisture does not adhere.
[0012]
[Action]
The colostomy device of the present invention is fixed around the stoma portion by the skin contact portion, and the stool or the like discharged from the stoma portion is the opening of the skin portion, or the first and second portions of the skin contact portion. The inner side of the multiple formed bags, that is, the center bag is received through each opening of the flange. When the discharge is finished, only the innermost bag is pulled out and removed from the skin or the second flange, so that the bag immediately outside the bag becomes the innermost bag. To stand by for the discharge of waste.
