Description

Technical Field

[0001] The invention relates to the technical field of kidney peritoneal dialysis equipment, in particular to a kidney peritoneal dialysis locator. Background Art

[0002] Peritoneal dialysis is a renal replacement therapy that uses the body's own peritoneum to replace renal function. The catheterization site is usually chosen in the middle or lateral abdomen because of the special structure of these locations, and the catheter can be located inside or below the rectus abdominis. This is not only conducive to fixing the catheter, but also allows abundant blood flow and fibrous tissue to wrap the peritoneal dialysis tube to prevent leakage. The peritoneal dialysis tube can be fixed to the abdomen through conventional surgery, laparoscopic catheterization, and percutaneous catheterization. The positioning device of the renal peritoneal dialysis tube is usually a specially designed skin patch or fixing belt used to fix the dialysis tube to the patient's abdominal skin to ensure that the tube remains stable during treatment. The design of these fixing devices can fix the dialysis tube in the correct position without unduly restricting the patient's activities or causing discomfort.

[0003] The traditional kidney peritoneal dialysis locator mainly has some technical defects in that the integral catheter is pasted and fixed to the abdomen by the application structure, among which the integral structure is a prominent problem. This structure is difficult to clean and disinfect thoroughly, and it is easy to breed bacteria and other microorganisms, increasing the risk of infection. Due to the lengthy structure, the integral dialysis tube is difficult to clean, and it is easy to accumulate dirt and blood residues, affecting the dialysis effect and patient health, and easily causing problems such as high risk of infection, inconvenience in use, difficulty in cleaning, pipeline blockage and poor durability. In addition, in the non-use stage, the lengthy external catheter seriously affects the patient's activities and is easy to cause the tube body to fall off during normal activities. Therefore, when designing a kidney peritoneal dialysis locator, it is necessary to fully consider these technical defects and seek new solutions to improve the dialysis effect and the quality of life of patients. In view of this, the existing problems are studied and improved, and a kidney peritoneal dialysis locator is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.
