[Industrial applications]

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

[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 narrow ureteral outlet, the surrounding area was sometimes soiled.

[0003]

[Problems to be solved by the device]

 The purpose of the present invention is to provide and develop a liquid absorbent material which has a shape that reduces the number of times of inserting the liquid absorbent material into the artificial bladder device and prevents urine leakage without damaging the inner wall of the device. The artificial bladder tool has a backflow prevention wall near the attachment port (urine intake port) and the ureter has a thin nozzle structure with an inner diameter of about 5 mm. I can't insert it. INDUSTRIAL APPLICABILITY The present invention can be inserted into such a tool, and can reduce the number of insertions to reduce the troublesomeness of the user to insert the liquid absorbent material, and can efficiently absorb and discharge urine, and has the function of not damaging the tool. It is to develop and provide materials. In particular, the challenge is to develop a material shape that reduces the number of insertions of the absorbent material into the artificial bladder device and reduces the complexity of insertion.

[0004]

[Means for Solving the Problems]

 As the liquid absorbent, a water-absorbing polymer having a high liquid absorbing power, or a fine dietary fiber which swolls quickly and becomes a gel is used. The water-absorbent polymer is in the form of fine particles like sugar and salt, but since the particles are hard and the shape is acute, it will damage the inner wall of the tool when used directly. Since the artificial bladder tool has a backflow prevention wall, it is not possible to insert the absorbent material from the mounting opening even at the first time. Moreover, since the urinary tract is thin and long with an inner diameter of about 5 mm and a length of about 80 mm, it is difficult to insert the water-absorbing polymer from the urinary tract. It takes time to insert fine dietary fiber as it is. It is necessary to have a function that allows the liquid absorbent material to be inserted efficiently from a thin ureter and a shape and structure that does not damage the tool. The liquid absorbent has the following structure in order to reduce the number of insertions of the liquid absorbent and to create a shape that does not require much labor. 1. Mixing gel-like water-absorbing polymer and hydrolyzed gelatin powder (a water-soluble protein obtained by hydrolyzing gelatin) that functions as a binder to make it easy to mold and have a diameter of less than 5 mm, It is shaped like a rod with rounded ends that is easy to insert and has a length of about 60 mm. 2. Mixing fine, specially processed dietary fiber, which absorbs water quickly and swells into a gel, with hydrolyzed gelatin powder particles, which serve as a binder, to make it hard to form, with a diameter of less than 5 mm and a length of about 60 mm. Molded into a rod shape with rounded ends for easy insertion. 3. Cover the surface of the molded rod-shaped liquid absorbent material with a thin film made of hydrolyzed gelatin powder. Or coating with sugar coating material. The structure will have the function of adjusting the dissolution time of the absorbent body after insertion, and the smoothness, strength, and moisture resistance so that it can be smoothly inserted into the artificial bladder device.

【Example】

 An example will be described with reference to the drawings. FIG. 1 is a side view showing the shape of the liquid absorbent material. Reference numeral 1 represents a rod-shaped liquid absorbent. The artificial bladder tool has a urinary drainage tube with an inner diameter of about 5 mm, and since there is a urine regurgitation wall near the attachment port, the liquid absorbent must be inserted through the urinary drainage tube. The inner diameter of the ureter is about 5 mm and the length is about 80 mm. Therefore, insert a liquid absorbent material with a diameter of less than 5 mm. The length of the rod-shaped liquid absorbent 1 should be as long as possible so as not to give the user a feeling of foreign matter because the length of the liquid absorbent material increases and the number of insertions increases if the liquid absorbent material is shortened. FIG. 2 is a schematic diagram showing the component constitution of the rod-shaped liquid absorbent material. 3 is a front cross-section of the rod-shaped liquid absorbent 1. Reference numeral 2 is particles of a water-absorbing polymer having a high absorptivity, which is one of the constituent components of the rod-shaped liquid absorbent. Reference numeral 3 represents particles of hydrolyzed gelatin powder (water-soluble protein obtained by hydrolyzing gelatin). The rod-shaped liquid absorbent 1 is obtained by mixing water-absorbing polymer particles and hydrolyzed gelatin powder particles and compression-molding them. A slight amount of water is added to the hydrolyzed gelatin powder particles to adjust the viscosity so that the mixture can be easily compression molded. The hydrolyzed gelatin powder acts as a binder. FIG. 3 is a schematic view showing a molding process of the rod-shaped liquid absorbent material. 4 is a pit forming a rod shape, and 5 is a compression rod. The compression rod 5 is moved up and down for molding.

FIG. 4 is a front sectional view showing a state in which the surface of the rod-shaped liquid absorbent material is coated. 6 is a coating layer made of hydrolyzed gelatin powder which covers the entire rod-shaped liquid absorbent material. The method of coating is by spraying a hydrolyzed gelatin solution. Another method is to pack gelatin in a film form. It plays a role in controlling the gelation speed of the rod-shaped liquid absorbent material depending on the size of the coating and film thickness. Another effect is to smooth the surface for easier insertion into artificial bladder devices. It has the advantages of increasing strength and preventing breakage, and increasing moisture resistance and storage stability. Another coating material used is the sugar-coated coating material used for medicine tablets. FIG. 5 shows a state where the rod-shaped liquid absorbent is inserted into the artificial bladder device. Reference numeral 7 represents a bag body for the artificial bladder tool. Since the urine storage portion of the bag has a space of about 100 mm in the longitudinal direction, it can be inserted even if the length of the absorbent material is about 90 mm. By making it longer, the number of insertions is reduced and the user's troublesome insertion operation is reduced. However, if it is too long, it may be easily broken or shortened, so a rod with a diameter of less than 5 mm and a length of about 60 mm should be used. When inserting the rod-shaped liquid absorbent into the urinary tract 8 of the device for artificial bladder, the rod-shaped liquid absorbent material to be inserted next is pushed in and inserted. The rod-shaped liquid absorbent used at the end is pushed in and then pulled out. About 0.5 g of water-absorbing polymer is contained in one rod-shaped liquid absorbent, but since the water-absorbing polymer with a urine absorption rate of 58 times is used, it is calculated as an artificial bladder device with a urine storage capacity of 200 cc-250 cc. Just insert 8 capsules. However, it is possible to achieve the object because the viscosity of urine becomes high even if half of the urine is absorbed even if the urine is not completely absorbed. Therefore, the number of rod-shaped liquid absorbents to be inserted may be four, which is necessary to absorb 100cc-125cc of urine. It only needs to be inserted 4 times. The remaining liquid such as urine plays a role in smoothing the discharge of the gelled water-absorbing polymer. Reference numeral 9 is a mounting port, and 10 is a urine backflow prevention wall.

Materials that can be used as a mixed material with the hydrolyzed gelatin powder other than the water-absorbing polymer include specially processed fine food fibers and wood pulp (mainly those that dissolve and swell in water rapidly (5-20 seconds). Component cellulose fiber). (The specially processed fiber is a fiber-like CMC obtained by carboxymethylating cellulose fiber. CMC is a water-soluble polymer, and the CMC in the form of fiber is rapidly dispersed in water and the whole swells. The shape and coating (having the property of gelling) and the coating are the same as the example of the rod-shaped absorbent material formed by using the water-absorbing polymer.

[0008]

[Effect of the invention]

 Since the liquid such as urine in the artificial bladder tool is held in the form of gel, the liquid does not sway due to moving the body and leakage does not occur. There is no leakage of smell. As it is a mixed material, it does not damage the inside of the artificial bladder device during insertion. The long rod-shaped structure of the liquid absorbent material reduces the number of times of insertion into the tool and reduces the troublesomeness during insertion. The ease of discharge is ensured, so the number of times the tool is used repeatedly is increased. Improve cost performance of tools. High comfort for the user when using the tool.
