[Problem that the invention seeks to solve]

As described above, various urine collection tools for women have been proposed in the past, but no urine collection tool, especially one for women, that satisfies all of the above-mentioned conditions has hitherto been provided. That is, the above-mentioned Utility Model Publication No. 49-8640 and Utility Model Publication No. 5
The urine collection device described in Publication No. 7-13052 gives the wearer a feeling of being a foreign body, and although it is made of an elastic material, it is molded in one piece, so it may cause skin irritation, and it is not breathable. It has the disadvantage of causing swelling of the genitals.

Furthermore, the female urine collection device described in the above-mentioned Japanese Utility Model Publication No. 58-152907 has some drawbacks in terms of how close it is to the human body, and there is a risk that excreted urine may leak if the wearer moves his or her body. have. Furthermore, the above-mentioned Utility Model Publication No. 56-41710 and Utility Model Publication No. 57-50
The product described in Publication No. 009 is designed to have ventilation so that the private parts do not become stuffy, but
There are problems similar to those described in Japanese Patent No. -152907.

This invention solves the various problems described above in conventional female urine collection devices, and provides a new urine collection device that satisfies all the conditions required for female urine collection devices, as well as a part of the female urine collection device. This invention has been made in order to provide a method for manufacturing a urine collection piece that constitutes a urine collection piece.

[Means for solving problems]

The female urine collection device according to the first invention includes a urine collection piece portion and a urine collection cup portion. The urine collection piece part is configured to tightly surround a silicone rubber molded body having a ring-shaped shape surrounding the external urethral meatus of a human body with a fabric by infiltrating the fabric with silicone rubber. The urine collection cup portion is constructed by wrapping a funnel-shaped molded body made of a flexible material such as rubber or synthetic resin with a cloth that is both water repellent and breathable. Then, the urine collection piece part is sewn in a cylindrical shape on the large diameter side of the urine collection cup part through a fabric that is both water repellent and breathable. This integrally sewn item is either sewn into a hole made in a predetermined part of the shorts, or detachably attached with a hook or the like.

Next, the method for manufacturing the urine collecting peel part according to the second invention is as follows:
It has at least the steps listed below. That is, (a) Step 2 of overlapping and temporarily adhering the fabric and the holding film to produce two laminated sheets. (b) A recess corresponding to the shape of a ring surrounding the external urethral meatus is formed on the surface. A step of spreading one of the laminated sheets with the fabric side facing up on the surface of the mold, and bringing it into close contact along the surface shape of the mold.

(c) A step of pouring a silicone fluid into the recessed portion of the mold with the laminated sheet interposed therebetween.

(d) On the surface of the laminated sheet closely attached to the mold surface,
A step in which another layer of the laminated sheet produced in step (a) is brought into close contact with the fabric side facing down.

(e) A step of subjecting the silicone fluid to a vulcanization treatment and molding it.

(F) A step of removing the integrated product completed through the above steps from the mold and peeling off the holding films covering the front and back surfaces.

(g) A step of leaving the silicon at an appropriate temperature for an appropriate period of time to complete the cross-linking reaction in the silicon.

(h) Cutting out the fabric in the central area surrounded by silicone rubber.

[For production]

In the female urine collection device according to the first invention, since the urine collection piece that comes into contact with the skin is constructed by surrounding a silicone rubber molded body with fabric, the device does not feel very uncomfortable and can be worn with ordinary underwear. There is less resistance compared to when it is attached to the surface.

In addition, the silicone rubber molded body curves freely along the curved surface of the human body's private parts, and on the other hand, the rear edge part is molded thickly, so it is difficult to deform in the width direction. Improve the closeness to the area.

In addition, the urine collection cup portion is entirely made of fabric except for the molded core material, and the continuous portion is also made of fabric, so it has excellent breathability. Since these fabrics are water-repellent, excreted urine does not become very damp while being discharged through the urine collection cup and the urine collection hose.

Furthermore, the molded body forming the urine collection piece part and the molded body forming the urine collection cup part are separate, and both molded bodies are connected through the fabric, so even if the wearer moves his or her body slightly, , - The movement of the urine collection piece part is not directly transmitted to the urine collection cup part and the urine collection hose, and conversely, even if the urine collection cup part or the urine collection hose is touched, the movement is immediately transmitted to the urine collection cup part and the urine collection hose. In other words, since the urine collection piece and the urine collection cup are flexibly connected via the fabric, their respective movements are separated between them, and the urine collection piece is transmitted to the human body's private parts. It is possible to maintain the tightness of the device, and it also makes it less uncomfortable to wear.

Next, in the method for manufacturing a urine collection piece according to the second invention, silicon in a fluid state is impregnated into fabric, and then the silicon fluid is subjected to a vulcanization treatment and molded to obtain a silicone rubber molded body. In order to do this, the fabric and silicone rubber are tightly bonded together. Further, since a holding film is laminated on one side of the fabric during the above manufacturing process, the silicone fluid does not permeate through the fabric and ooze out to the fabric surface.
