The present invention is a device worn for waterproofing the exit portion of the induction pipe of the renal failure patients with peritoneal dialysis. Patients with peritoneal dialysis have a hole in the lower abdomen and a silicone hose guide tube is inserted into the body to fix it, and the body fluid is discharged out of the body by talking to the guide tube. Water sores often cause outlet inflammation due to bacterial infection.The present invention covers the induction tube and the outlet area with a waterproof cover before peritoneal dialysis renal failure patients, so that the outlet area does not get wet during the shower, preventing infection by water, thereby preventing the outlet inflammation and taking a shower. It is a device that does not need to disinfect after shower by separating and disinfection.This product is made of bowl-shaped silicone rubber with a diameter of 10 cm and a height of 5 cm, a stainless steel outer cover that covers the cover, and a synthetic fiber that allows the cover to be worn on the abdomen. The waist is made of material. The rubber cover is excellent for waterproofing as it is attached to the body, but the material is soft, and when it is tightened with a belt, the rubber cover is not maintained as a whole, but the pressure is not even as it is squashed. It has a double structure with a stainless steel outer cover on it.At this time, the stainless steel cover serves as a skeleton of the rubber cover to maintain the overall shape and to press the pressure of the rubber belt evenly.Before taking a shower, put the induction tube in the cover, cover the outlet with a cover, tighten the waistband tightly, and the waistband presses on the cover. When using this product, the outlet is not wetted with water, which prevents bacterial infection caused by water, thus preventing the inflammation of the outlet and eliminating the need for sterilization after showering. It can have a decreasing effect.Induction pipe, outlet part, rubber
