Description

Waterproof cover structure for accommodating peritoneal dialysis tube and its sealing rubber ring

The invention relates to a waterproof cover structure, in particular to a waterproof cover structure for accommodating a peritoneal dialysis tube.

When kidney tissue cannot be repaired due to disease, kidney function will gradually decline, which is called chronic kidney disease. However, when mild chronic kidney disease occurs, there will not be any obvious symptoms, so it is not easy for patients to find that they have symptoms of mild kidney disease. In addition, everyone's kidney function declines at different rates, so if the kidney function gradually declines, the patient's body will not be able to eliminate the metabolic waste generated in the body by itself. With the intensification of chronic kidney disease, patients are usually unable to effectively improve and control their condition through medication and diet control. Therefore, alternative treatments are needed to help eliminate metabolic waste generated in the body. Current alternative treatments for chronic kidney disease include peritoneal dialysis, hemodialysis and kidney transplantation.

The hemodialysis system uses an external hemodialysis machine to purify the blood; first, an arteriovenous catheter is established in the patient's arm by surgery, and it takes at least one month before the hemodialysis treatment can be performed. During treatment, two needles are inserted into the catheter. The blood flows from one of the needles to the outside of the body and enters the artificial kidney (ie hemodialysis machine) to remove the metabolic waste and water produced in the body. The purified blood is then passed through the other needle. Drain the flow back into the body. Patients need to go to the hemodialysis center (or hospital) for treatment 3 times a week, each for about 4 to 6 hours. Because hemodialysis cannot continuously remove waste products in the blood like a normal kidney, patients must have restrictions on their diet, especially the intake of salt, water and potassium ions. Generally speaking, patients have to go to a specific medical place for hemodialysis treatment, and hemodialysis is very time-consuming; on the other hand, hemodialysis patients need to strictly control their diet, so hemodialysis treatment of chronic kidney disease may be harmful to the patient’s life And work caused great impact and inconvenience.

Kidney transplantation, commonly known as "kidney transplantation," is a treatment that allows patients to return to their original life. The patient’s original kidney will not be removed, but another healthy kidney will be implanted in the patient to replace the original damaged kidney function. Kidney transplantation can be donated by the fifth-class family members or by the kidney donation of brain death patients; blood must be drawn for tissue matching, and then the transplant can be performed. In addition, since kidney transplantation is an allogeneic transplantation, it is necessary to take anti-rejection drugs for a long time after kidney transplantation. Although kidney transplantation allows patients to return to their original lifestyles, the technical conditions for kidney transplantation are extremely high and patients have to wait an extremely long time before they may have a chance to undergo a kidney transplant. Therefore, for chronic kidney disease, kidney transplantation is not Active alternative therapy.

In the composition of the human body, the peritoneum is a thin film covering the internal organs in the abdominal cavity, which is rich in microvascular distribution. Peritoneal dialysis is a way to treat chronic kidney disease using the peritoneum as a way to filter and remove water and waste from the body. First, a permanent catheter needs to be implanted in the patient's abdominal cavity, and the dialysate is injected into the abdominal cavity through the catheter for a period of time. The peritoneum is used as a semi-permeable membrane for dialysis to trap body waste and water in the dialysate in the abdominal cavity and drain it out. . Regarding the exchange technique of peritoneal dialysis, the nursing staff will give instruction and repeated practice by the patient. After learning the dialysis-related care methods, the home peritoneal dialysis treatment can be performed independently. Generally, the course of peritoneal dialysis includes drainage, infusion and indwelling; the drainage step refers to draining the peritoneal fluid into the empty drainage bag for about 10 to 15 minutes; after the drainage step is completed, use about 10 minutes to inject fresh dialysate into the peritoneal cavity; After the injection step is completed, the dialysate can stay in the abdominal cavity for about 4 to 6 hours. During the indwelling time, the patient's movement is basically unlimited, and only a few fluid exchange procedures are required according to the doctor's instructions. In short, the use of peritoneal dialysis treatment can greatly reduce the inconvenience and impact of patients' life and work; in terms of diet, patients on peritoneal dialysis do not need to strictly limit the intake of salt, water and potassium ions. Therefore, compared with hemodialysis treatment, peritoneal dialysis treatment is generally suitable for most patients with chronic kidney disease.

The peritoneal dialysis catheter system is set in the patient's abdomen and connects the body and the body. In use, it should be properly cleaned and taken care of in accordance with the instructions of the medical staff to avoid pollution around the dialysis catheter and cause peritonitis and other major diseases. Therefore, patients with peritoneal dialysis catheters are taught to take a bath instead of showering to ensure hygiene around the dialysis catheter and avoid bacterial infection.
