Abstract
Description
[Technical Field]
[0001] The present invention is a device for assisting male urinary function. [Background technology]
[0002] Numerous devices have been proposed to date, including cylindrical hard devices secured to the waist with bands or strings and urination aids with a storage compartment connected by a tube, bulky disposable diapers, and spare incontinence pants. However, these devices are not only difficult to use, but also uncomfortable to wear, causing people to lose motivation to be active and refrain from going out, and reducing fluid intake can lead to other illnesses, and the effects are not alleviated.

[0004] Summary of the Invention [Problem to be solved by the invention]
[0005] To provide a urination assisting device which has a shape that is difficult to distinguish from the outside when worn, is easy to wear and simple to relieve oneself, collects and stores a large amount of urine, and can easily dispose of the urine. [Means for solving the problem]
[0006] By drilling suitable holes in a commercially available storage container (a resin bag with a sealed zipper) and processing it into a urine collection and storage container, we can create a low-cost urination aid that is invisible to the naked eye. An elastic retaining string holds the bag at the base of the penis to prevent it from falling off. [Effects of the Invention]
[0007] The volume inside the bag can be changed by changing the length of the zipper part (2) of the zippered resin bag (1), so it can accommodate small to large amounts of urine leakage without changing the structure. By using a resin bag (1) with a zipper, the thin resin bag adheres tightly to the penis and thighs, and it is not possible for others to know from the outside that a urination aid is being worn. By processing a commercially available resin bag (1) with a zipper, a reusable urination aid can be provided at low cost. [Brief explanation of the drawings]
[0008] [Figure 1] 1 is an explanatory diagram showing an instrument of the present invention.
[0009] Figure 1 is an overall view of a male urination aid. One edge of a resealable plastic bag (1) is cut from the welded end of the zipper (2) toward the bottom (12) of the bag, starting from a position that does not affect the closure of the zipper (2). Adhesive tape (4) is applied to the edge of the cut to reinforce it. The adhesive tape (4) is applied longer than the length of the cut, and the excess is folded back to form a tab shape (4a). Several string holes (3) are opened in the cut reinforced with adhesive tape (4) for a retaining string (8). Further cuts are made from the end of the cut toward the opposite side of the edge, and adhesive tape is applied to the end of the cut (5) to reinforce it and prevent the bag from tearing, creating a flap (6) for penis insertion. The end of the slit (5) is welded (10) with a welding and sealing machine to the opposite side of the slit to form a vertically long container, and the bottom of the bag (12) is cut off and removed, which makes it comfortable to wear inside pants. It can also be used as a large-capacity container without welding (10), but it will not be comfortable to wear. The elastic holding string (8) is passed alternately through the string holes (3) and then the ends of the string are tied to make a loop. DETAILED DESCRIPTION OF THE INVENTION
[0010] The size of the resealable plastic bag (1) is such that the length of the resealable portion (2) is 100 mm or more and the depth is 50 mm or more. A 50 to 100 mm cut is made on one side of the edge of the resealable plastic bag (1), starting from the welded end of the resealable plastic bag's zipper (2), from a position that does not affect the closure of the zipper (2) toward the bag bottom (12), and the cut edge is reinforced with adhesive tape (4). The adhesive tape (4) is applied longer than the cut length, and the excess is folded to form a tab shape (4a). Several string holes (3) are opened in the reinforced portion for the retaining string (8), and a 50 to 100 mm cut is made from the end of the cut toward the opposite side of the edge, and adhesive tape is applied to the end of the cut (5) to prevent tearing. The elastic retaining string (8) is passed through the string hole (3) opened in the reinforced cut part to hold the bag at the base of the penis and prevent the zippered resin bag (1) from falling off. [Example]
[0011] The flaps (6) of the resealable plastic bag (1) are opened to the left and right to insert the tip of the penis. The zipper (2) is opened to widen the insertion path, and the penis is pulled in so that the flap portion of the urination aid can be attached to the base of the penis. By pulling up the retaining string (8), the flaps (6) of the insertion section envelop the penis from both sides, securely holding the resealable plastic bag (1) at the base of the penis. Penis size and length vary from person to person, and their condition changes daily, so the length of the slit must be adjusted. However, the retaining string (8) is elastic, so it can accommodate slight changes. Even when the penis is facing upward, the flap portion (6) conforms to its shape, preventing it from falling off. By placing a polymeric absorbent (11) or similar material inside the resealable plastic bag (1), leaked urine solidifies, reducing the sound of water when moving. Using a bag with a longer zipper portion (2) allows for prolonged use. People with poor finger mobility can use a bag with a zipper (2) with an opening and closing slider (7) to open and close the zipper (2) quickly. During penis insertion and normal urination, opening the front zipper (2) allows for easy forward penis removal and insertion, allowing for forward urination while standing without removing the device. Even if a patient is unable to urinate in time for a toilet and leaks urine, opening the front zipper (2) allows for easy discharge of accumulated urine. Furthermore, the urination aid is reusable, making it cost-effective. The amount of urine collected varies depending on the zipper length and bag width; however, a 35 cm zipper (2) and 10 cm bag width can collect approximately 200 cc. Leaked urine can be prevented from leaking outside the device by inserting a polymeric water absorbent (11) into the bag beforehand, which will absorb and solidify the urine. When working or driving while sitting in a chair, wearing a bag with a zipper length of approximately 55 cm places the collection area below the knees for added security. Larger zippered plastic bags can be made by reusing clothing storage bags. Normally, when the retaining string (8) is fastened to a shirt button, it stretches and contracts with the movement of the body to prevent the bag from falling off, but if you don't have a shirt with buttons, you can hang the retaining string (8) without it being noticeable by using a name tag strap (9) or the like.

Claims
1. A slit is made along one edge of the zip-locked plastic bag (1), originating from the welded end of the zipper (2) at a position that does not affect the closure of the zipper (2), toward the bag bottom (12), and several string holes (8) are opened along the slit. Further slits are made from the slit end toward the opposite side of the edge to form a membrane-like insertion opening (6). By passing an elastic holding string (8) through the string hole (3) opened in the slit and inserting the penis into the insertion opening (6) and then pulling the holding string (8), the zip-locked plastic bag (1) becomes a container for the penis and a container for leaked urine. When urinating in a toilet, normal urination can be performed without removing the device by opening the front zipper (2), and the device can be reused as is after the collected leaked urine has been discharged.
2. The urination aid according to claim 1, characterized in that an elastic retaining string (8) is passed through the string hole (3) and the membrane-like insertion opening (6) wraps around the penis from both sides, so that even if the size or orientation of the penis changes, the elastic retaining string (8) holds the zippered resin bag (1) at the base of the penis, preventing the zippered resin bag (1) from falling off.
3. The urination aid according to claim 1, characterized in that by using a resin bag (1) with a zipper, the bag is deformed to fit thinly against the penis or thighs, and the fact that the urination aid is being worn is not apparent to others from the appearance in everyday life.
