Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 It is used to comfortably use the temporary excrement retainer used by people who are forced to have an artificial anus or artificial bladder due to a cancer disease.

[0002]

[Prior art]

 Temporary excrement holders (hereinafter referred to as “equipment”) in the artificial anus and artificial bladder excrete watery feces and urine, so if careless, there is a risk of leakage from the attachment port before treatment in the toilet . The user always wears equipment, but when walking, liquids such as urine and watery stools may move (dance) in the equipment and may leak from the wearing mouth. Since the urine suddenly emerged from the defecation opening, there was a possibility that the surrounding area would be soiled. There was no sheet-shaped absorbent material that could be shared by both of these tools. Further, there was no liquid absorbent sheet incorporating a deodorant.

[0003]

[Problems to be solved by the device]

 The problem is to add the following functions to the liquid-absorbent sheet that is put in the tool. ● Improve the speed of liquid absorption and gelation, make it possible to adjust the insertion amount, and make it a shape that can be inserted from the thin urinary tract of artificial bladder tools. That is, it will be a common liquid-absorbent sheet that can be used for both artificial anastomosis tools and artificial bladder tools. ● The absorbent sheet inserted in the tool does not damage the inner wall of the tool before absorbing liquid. ● The liquid absorbs quickly, and when it absorbs, it turns into a gel and prevents leakage of watery feces, making it easy to excrete. ● Add deodorant to the liquid absorbent sheet to save the trouble of putting the deodorant into the tool by another means.

[0004]

[Means for Solving the Problems]

 ● The basic shape of the water-absorbent sheet is a 100 mm x 100 mm quadrilateral, and the liquid-absorbent sheet has multiple edges with a width of less than 5 mm and a length of about 90 mm, leaving edges of less than 5 mm in parallel. Put in. This cut increases the liquid absorption surface and accelerates the gelation speed. It provides the function to adjust the insertion amount by manually tearing apart the edge part before inserting it into the tool. Further, it can be formed into a rod shape that can be easily inserted into the urinary tract of the artificial bladder device. ● The water-absorbent polymer is in the same fine particles as sugar and salt, but since the granules are hard and the shape is acute, using them alone will damage the inner wall of the tool. Therefore, we used "MA-SAP sheet = Honshu paper (currently Oji Paper Co., Ltd.) non-woven adsorbent nonwoven fabric manufactured by the dry method" mixed with water-absorbing polymer, and made it a quadrilateral sheet of a size easy to insert into tools. . ● As the liquid absorbent, use a water-absorbing polymer that has a high liquid absorbing power and turns into a gel when it absorbs liquid, or fine dietary fiber that swells quickly and becomes a gel. A liquid-absorbent sheet having the above-mentioned material combination and shape was prepared. ● Add deodorant to the absorbent sheet that will not deteriorate when not in use. It was solved by the above means.

【Example】

 An example will be described with reference to the drawings. Example 1 FIG. 1 is a perspective view of a shape in which a liquid absorbent sheet is used in a tool as seen from above. Reference numeral 1 denotes a liquid absorbing sheet, which has a thickness of about 1.5 mm. The size of this liquid-absorbent sheet is 100 mm × 100 mm, which is basically easy to insert from the mounting opening of the colostomy tool and requires a small number of insertions. 2 is a notch for making a rod shape that can be easily inserted into the artificial bladder tool. Cut into parallel lines with a width of less than 5 mm, leaving an edge of less than 5 mm. This notch serves to tear the edge in the longitudinal direction to form a rod with a width of less than 5 mm. FIG. 2 is a schematic view of the structure of the device for artificial bladder. 3 is a mounting port, 4 is a urine reflux wall, and 5 is a urinary tract. In order to use the liquid absorbent sheet for the artificial bladder device, since it has a backflow prevention wall, it must be inserted from the urinary tract having an inner diameter of 5 mm during the wearing except for the first time. In order to make it a common absorbent sheet that can be used for both colostomy tools and artificial bladder tools, a shape that allows a 100 mm x 100 mm absorbent sheet to be inserted from the urinary tract of an artificial bladder tool, that is, It is necessary to make a rod shape with a diameter of less than 5 mm. Although it is used as a 100 mm x 100 mm sheet in an artificial anus tool, the slits make the liquid absorption surface wider and the liquid absorption speed faster, and the role of eliminating the unevenness of the initial liquid absorption surface. Fulfill. Also, since the separation is easy, it is easy to fine-tune the insertion amount. The principle of manufacturing the liquid-absorbent nonwoven fabric by the dry method is as follows: natural cellulose fibers of 0.8-1.5 mm length as supporting fibers and heat-melting substances (fibers) that exert an adhesive function at 131 degrees Celsius 98: 2- A mixture of 60:40 is used, and a liquid-absorbent (adhesive) substance is mixed therein in the range of 2-400% based on the weight of the supporting fiber. Natural cellulose, adhesive hot-melt fibers, and liquid-absorbent (adhesive) materials are uniformly mixed in a dry state in an air stream and heat treated at a temperature above the melting point of the adhesive hot-melt fibers in a web forming device. Form into. Particles of a liquid-absorbing substance such as a water-absorbing polymer are fixed so as to be woven into the fiber. Therefore, by using this non-woven fabric for the liquid-absorbent sheet, it is not necessary to use a method in which the granular water-absorbing polymer that easily damages the inner wall of the tool is directly put in the bag and used.

Example 2. A plan using a liquid-absorbent sheet mixed with a water polymer “MA-SAP sheet = adsorbent nonwoven fabric manufactured by Honshu Paper Co., Ltd. (currently Oji Paper Co., Ltd. by a dry method)” is shown. FIG. 3 is a cross-sectional view of the water absorbing sheet “MA-SAP sheet”. 6 is a taste that decomposes when it comes into contact with the liquid in the tool. A tissue 6 that is decomposed when touched by liquid is attached to the front and back surfaces to create a soft-touch contact surface. The middle layer is formed of a natural cellulose fiber 7 and a water-absorbing polymer 8 with a polyolefin-based powdery adhesive material 9. The natural cellulose fibers 7 and the powdery adhesive material 9 are mixed and bonded to each other by heat to form a non-woven fabric holding a water absorbing polymer. These fibers cause a capillary phenomenon to rapidly supply the liquid to the water-absorbing polymer particles and cause them to gel. Fibers also decompose quickly when in contact with the liquid in the device. The MA-SAP sheet has a thickness of about 1.5 mm and is soft and flexible. The liquid absorption is 9000 g / m ² or more, and the liquid absorption is extremely high, which is suitable for use in tools. FIG. 4 shows variations in how to make the cuts. In the basic plan shown in FIG. 1, a cut having a width of less than 5 millimeters is made with a length of about 90 mm, but in a variation, a short connecting portion 10 is provided in the middle of the cut, and the cut has multiple stages. The figure shows the case of two stages. Prevents disparity due to long cuts.

Example 3. It is a plan to use a non-woven fabric that is specially processed so that natural cellulose fibers are quickly dissolved (5-20 seconds) in water and swollen to form a gel in the liquid absorbent sheet. The special processing is carboxymethylation of cellulose fibers, which is called fibrous CMC. CMC is a water-soluble polymer and rapidly gels. The fibrous material is used as a non-woven fabric. Make a cut in this to commercialize.

Example 4. The idea is to add a deodorant to the absorbent sheet and eliminate the double labor of adding the deodorant by another means. FIG. 5 is a schematic diagram showing a usage pattern of the deodorant material. The main component of the odor of excrement collected in the device is ammonia. The figure shows a liquid absorbent sheet with the function of deodorizing other odors, mainly ammonia contained in this excrement. Reference numeral 11 shows a state where the deodorant material is applied to the liquid absorbing sheet, and 12 shows a state where the deodorant material is mixed in the liquid absorbing sheet. As the deodorant, a deodorant “green tea extract MF” manufactured by Maruzen is used. The deodorant "green tea extract MF" is a powdery deodorant obtained by extracting tea leaves with hot water, refining with alcohol, and then drying. The ammonia deodorizing power is shown by the fact that the residual ratio of ammonia after adding 1% of "green tea extract MF" to a liquid containing 75 PPM of ammonia is 3%. The material shape is powder. When applying, mix with water and spray or coat. If it is mixed, mix it with the water absorbent polymer or the fiber material when forming the sheet.

[0009]

[Advantages of the Invention] A quadrilateral liquid-absorbent sheet that is easy to insert into a tool has a parallel line cut with a width of less than 5 mm, which widens the liquid-absorbing surface and increases the liquid-absorbing speed. The bias was reduced. Depending on the amount of excrement, the liquid absorbent sheet can be finely torn into a convenient amount for fine adjustment insertion. In addition, it has become possible to make it into a rod shape that can be inserted from the ureter of the artificial bladder tool. Liquid such as watery stool and urine in the artificial anus and artificial bladder is held in gel form, so there is no sway of liquid caused by moving the body and leakage does not occur. There is no odor leak. The liquid-absorbent sheet mainly uses a non-woven fabric in which a water-absorbent polymer is fixed by fibers. The non-woven fabric does not damage the inside of the artificial anus and the artificial bladder tool during insertion. Since the ease of discharge is secured, the number of times the tool is used repeatedly is increased. Improve the cost performance of equipment. High comfort for the user when using the tool. The absorbent sheet was mixed with or applied with deodorant, eliminating the need for the double labor of putting the deodorant into the tool from a separate container.
