AI Technical Summary
Patients wearing a stoma face the risk of soiling their body and clothing with urine during pouch exchange due to decreased adhesiveness of the pouch panel from moisture and unexpected urination, especially when changing the pouch outside the bathroom.
A waterproof cup with absorbent material and elastic cords is used to cover the stoma area, secured with S-shaped hooks and crimp terminals, ensuring secure fit and quick absorption of any leakage.
Prevents unexpected urine leakage, maintaining hygiene and comfort during pouch changes without assistance, and is easy to use and reusable.

Abstract
Description
Technical Field
[0001] The present invention relates to a simple and reusable urine leakage prevention device for preventing unexpected urine leakage when a pouch for storing urine is exchanged by a person wearing a stoma (artificial bladder).
Background Art
[0002] Patients wearing a stoma need to exchange the pouch every few days, and there was a risk of soiling the patient's body and clothing with urine during pouch exchange.
Summary of the Invention
Problems to be Solved by the Invention
[0003] Conventionally, there was a method of exchanging the pouch in the bathroom and washing away the leaked urine, but there was a problem that the adhesiveness of the panel of the pouch (the adhesive part for fixing the pouch to the skin) was likely to decrease due to moisture and water droplets. Also, when trying to exchange the pouch after leaving the bathroom and wiping the body, unexpected urination occurred during that time, and there was a problem that the clean body became dirty again.
[0004] The present invention aims to solve the above problems by covering the hole through which urine in the stoma is discharged with a waterproof cup (such as a plastic cup) containing a water-absorbing material such as gauze, which is wound around the body and fixed with an elastic string when exchanging the pouch, thereby preventing the body and clothing from being soiled by unexpected urine leakage, and enabling the skin around the stoma hole to be smoothly wiped and dried with both hands.
Means for Solving the Problems
[0005] This invention comprises a waterproof cup and an absorbent material placed inside the cup. A total of four through-holes are formed on the upper side of the cup, two on each side at opposing positions. A first waterproof cord is passed through two adjacent through-holes, and a second waterproof cord is passed through the remaining two adjacent through-holes. Crimp terminals are attached to both ends of the first and second waterproof cords, and S-shaped hooks are connected to each crimp terminal. A ring is attached to the side of each S-shaped hook that is not connected to a crimp terminal, and an elastic cord is attached to each ring.
[0006] This configuration allows the cup to securely cover and hold the stoma area by wrapping an elastic cord around the stoma user's body. As a result, any unexpected urine leakage that may occur during pouch changes is quickly absorbed by the absorbent material, allowing for comfortable and hygienic pouch changes without wetting the user's skin or clothing. [Effects of the Invention]
[0007] This invention can be easily manufactured without using expensive materials, and can be reused by replacing the absorbent material and washing the cup. Furthermore, by using an elastic cord, it fits easily to the body shape and is easy to put on and take off, and the adoption of an S-shaped hook allows for self-attachment and removal, enabling independent use without assistance. In addition, because the cup fits snugly against the stoma opening, it is easy to wipe and dry the wet skin around the stoma opening, making it hygienic and comfortable to use. [Brief explanation of the drawing]
[0008] [Figure 1] This is a drawing of the device. [Modes for carrying out the invention]
[0009] This device consists of one waterproof cup (such as a plastic cup), two waterproof strings, two crimp terminals, two S-shaped hooks, two rings, one elastic string, and an absorbent material such as gauze. A hole is made in the top of the cup through which the strings are threaded and secured with the crimp terminals. The crimp terminals and the elastic string are connected via the rings. By wrapping the elastic string around the body, the stoma area is covered with the cup, and the absorbent material such as gauze placed in the cup absorbs the urine. [Examples]
[0010] The following describes an example with reference to the attached drawings.
[0011] 1 is a waterproof cup, and a total of four through-holes are formed on the upper side of the cup, two on each side.
[0012] Reference numeral 2 denotes a waterproof cord, and the first waterproof cord is passed through two adjacent holes, and the second waterproof cord is passed through the remaining two adjacent holes, so as to pass from the outside to the inside of the cup and then back out to the outside.
[0013] The first and second waterproof cords are secured at both ends by the crimp terminals 3.
[0014] 4 is an S-shaped hook that connects to the annular portion at the tip of the crimp terminal.
[0015] 5 is a ring, which is connected to the side of the S-shaped hook that is not connected to the crimp terminal.
[0016] The ring is attached to the elastic cord (7), which has a loop at the end, using 6 cable ties, thus integrating all the parts together.
[0017] When using the pouch, remove the S-shaped hook from the ring portion of the crimp terminal, place an absorbent material such as gauze into the cup, stretch the elastic string and wrap it around the abdomen like a belt, and then attach the S-shaped hook to the ring portion of the crimp terminal to secure it to the body, preventing accidental urine leakage while allowing for easy pouch changes. [Industrial applicability]
[0018] This invention is useful as a stoma care product in medical settings and contributes to improving the daily quality of life (QOL) of patients who manage their stomas at home. [Explanation of symbols]
