Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 It is used to comfortably use the temporary waste retention device used by people who have had artificial bladder or anus due to cancer disease.

[0002]

[Prior art]

 Urine is always excreted in the conventional temporary waste retention device for artificial bladder (hereinafter referred to as artificial bladder device), so if careless, it may accumulate too much and leak from the attachment port before it is processed in the toilet. was there. The user wears artificial bladder equipment all the time, but when walking, liquid such as urine may leak from the wearing opening due to large movement (dancing) in the equipment, and when draining in the toilet. Since it came out vigorously from the thin excretion opening, the surrounding area was sometimes soiled. Even in the case of a temporary waste holder for colostomy (hereinafter referred to as a colostomy tool), similar problems were likely to occur when watery feces such as diarrhea occurred. In the case of colostomy devices, sanitary napkins are used as water absorbents through the mounting port and drain port to absorb water and improve the water content. However, these swell as large lumps that cannot be drained through the drain port. This made it impossible to use the colostomy device repeatedly. Recently, there is a product with a water-absorbent polymer sandwiched between paper.In this product, it is easy to decompose after absorbing water, so it can be loosened by rubbing by hand, but it is bulky at the time of insertion. It had the drawback of being difficult to insert. In particular, the artificial bladder tool was prone to urine leakage because it had a structure that the absorbent material could not be easily inserted.

[0003]

[Problems to be solved by the device]

 It is a development and provision of a liquid absorbent material that is easy to insert into artificial bladder and colostomy devices, prevents urine leakage without damaging the attachment port or inner wall of the device, prevents watery feces leakage, and does not damage the user's skin. . (In the case of a colostomy device, there is no backflow prevention wall, and since the liquid absorbent material is inserted from the mounting port for the first time, the mounting port may be damaged.) For the artificial bladder device, near the mounting port (urine intake port) Since the backflow prevention wall is provided and the discharge pipe has a thin nozzle structure with an inner diameter of about 5 mm, a large-sized absorbent material cannot be inserted inside. The present invention aims to develop and provide a liquid absorbent material having a shape that can be inserted into such a tool, a function of facilitating water absorption and drainage, and a function of not damaging the skin or the tool. It is also necessary to provide a liquid absorbing material that functions similarly to the watery stools of colostomy device users.

[0004]

[Means for Solving the Problems]

 A water absorbing polymer having a high liquid absorbing power is used as the liquid absorbing liquid. The water-absorbent polymer is in the same fine-grained state as sugar and salt, and since one grain is hard and the shape is acute, it will damage the inner wall of the tool when used directly. The colostomy device allows the absorbent material to be inserted from the mounting port only at the first use, and the drain port is relatively wide when reused, so that the absorbent member can be easily inserted while being mounted. On the other hand, since the artificial bladder device has a backflow prevention wall, it is not possible to insert the absorbent material from the mounting opening even at the first time. Also, since the inner diameter of the outlet is about 5 mm, it is difficult to insert the water-absorbing polymer from the outlet. It is necessary to have a function that allows the absorbent material to be inserted through a thin discharge pipe and a structure that does not damage the equipment. Based on these prerequisites, the liquid absorbent has the following structure. 1. The water-absorbent polymer is incorporated into a capsule with a rounded shape that is easy to insert (diameter less than 5 mm) and has rounded ends. 2. Compress the fine fibers that have the property of forming a gel by dispersing in a liquid to make it easy to insert. 3. Mix a water-absorbing polymer into a gelled material with high water retention (eg: propylene glycol mixed with propylene glycol mixed with a special material that enhances water retention as a cross-linking agent). It was solved by.

【Example】

 There are three embodiments in the examples (capsule system, tablet system, mixing method in gel medium). This will be described in order with the drawings. Example 1 (capsule system) FIG. 1 shows a capsule containing a water-absorbing polymer. A is a sectional view of the side surface of the capsule. B is a front view. 1 is a cap portion of the capsule, and 2 is a body portion. 3 shows a water absorbing polymer. The length and diameter of the capsule including the capsule cap and body should be such that it can be inserted into a tool, but for a discharge pipe with an inner diameter of 5 mm, the capsule should be less than 5 mm in diameter. Since the length of the discharge pipe is about 50 mm, the length is about 10 mm. The capsule is inserted with an elongated rod. The capsule material is gelatin, but it has a characteristic of rapid dissolution especially in watery feces and urine components (salt concentration is 0.9%) (normal drug capsules dissolve in 1-2 minutes). Use gelatin with. Capsules of the above size can contain about 0.1 grams of water-absorbing polymer. As the water absorbing polymer, one having a high water absorption rate of about 58 times is used. The urine storage capacity of the artificial bladder is 200 cc-250 cc. Although it is sufficient to insert 40 capsules in the calculation, it was found in the experiment that the viscosity of urine and watery feces can be increased by absorbing half the amount without absorbing all the amount of water. The number of capsules required to absorb half of 100cc-125cc of water is about 20. The remaining liquid such as urine plays a role in smoothing the discharge of the gelled water-absorbing polymer. FIG. 2 shows the water absorption state of the water absorbing polymer after the gelatinous substance of the capsule is dissolved. While the shape of the incorporated water-absorbing polymer is maintained, the water-absorbing polymer gradually swells from the surroundings, so that fine particles of the water-absorbing polymer do not suddenly disperse and damage the inner wall of the tool.

Example 2 (Tablet method) This method was specially processed to dissolve fine dietary fiber and wood pulp (mainly composed of cellulose fiber) in water quickly (5 to 20 seconds) to form a swollen gel. Use one. (The specially processed fiber is a fiber-shaped CMC obtained by carboxymethylating cellulose fiber. CMC is a water-soluble polymer, and CMC in the form of fiber is swollen as a whole by swiftly dispersing in water. With the nature of becoming). This tablet method uses this special water-absorbing material, and compression-molds it into a shape that can be easily inserted into artificial bladder tools and colostomy tools (eg cylinders with rounded ends, discs, spheres, cones, etc.) To do. FIG. 3 shows a columnar shape that is compression-molded and has rounded ends. C is a side sectional view. D is a front view. Reference numeral 5 is a liquid absorbing material having an elongated shape that can be easily inserted into the discharge pipe. Reference numeral 6 also indicates a portion having a rounded tip for easy insertion. FIG. 4 is a view of the artificial bladder tool seen from above. 7 is a bag portion for storing urine. Reference numeral 8 is a mounting opening for mounting the tool on the human body. From here, urine is constantly discharged into the bag. Reference numeral 9 is a urine backflow prevention wall. The urine that entered through the fitting port enters the storage bag part 7 through the hole with the check valve. Reference numeral 10 is a urine discharge tube. Reference numeral 11 is an opening / closing tool for the discharge pipe. Eliminate the urine that has accumulated during discharge. Reference numeral 12 is a capsule containing a water-absorbing polymer. Reference numeral 13 is a liquid absorbing material formed by compressing fine fibers. Indicates the insertion status. FIG. 5 shows a colostomy tool. Reference numeral 14 indicates a bag. The bag does not have a backflow barrier. The outlet 15 is wider than the artificial bladder device. Therefore, insertion of the absorbent material is relatively easy. Reference numeral 16 is an opening / closing tool. Reference numeral 17 is a mounting opening. This tool also uses three types of liquid absorbing materials.

Example 3 (Method of mixing with gel medium) This method is a gel-like medium substance (propylene glycol with a special cross-linking agent that enhances water retention) that is easy to inject into artificial bladder and colostomy devices. It is the one in which a water-absorbing polymer is mixed. Since the gel-like substance encapsulates the particles of the water-absorbing polymer, it does not damage the inner wall of the device. In addition, since the gel medium material has a high water retention property, water does not transfer to the water absorbing polymer. Therefore, the water-absorbing polymer in the gel-like medium substance injected into the device absorbs urine and watery feces and gels. FIG. 6 is a schematic diagram of a liquid absorbent material 18 in which a water-absorbing polymer is mixed with a gel-like medium substance. Reference numeral 19 indicates particles of a water-absorbing polymer, and 20 indicates particles of a medium substance (special propylene glycol) which retains water and becomes a gel. FIG. 7 shows an injection tool for injecting a liquid absorbent material into an artificial bladder tool. Reference numeral 21 is an injection container, and 22 is an extruding cylinder. An injection nozzle 23 is inserted into the discharge pipe. FIG. 8 shows a state of injecting a gel absorbent material into the storage bag portion 7 of the artificial bladder tool.
