Description

Peritoneal dialysis catheter external fixing device for treating kidney diseases

Technical Field

The invention relates to an external fixing device of a peritoneal dialysis catheter for treating kidney diseases, belonging to the technical field of medical instruments.

Background

Chronic renal failure is a progressive progression of various chronic kidney diseases, causing irreversible loss of nephrons and kidney functions, leading to clinical syndromes characterized by retention of metabolites, disturbance of water electrolyte and acid-base balance, and endocrine dyscrasia, with uremia as the end stage of chronic renal failure.

With the development of society and the aging of population, the incidence of chronic kidney diseases and chronic renal failure caused by the chronic kidney diseases increases year by year in recent years, about 220-270 million people with end-stage renal failure are in the world every year, and patients receiving dialysis treatment are growing at a rate of 10-12% each year. In recent years, especially in elderly patients, the number of chronic renal failure caused by kidney damage due to diabetes, hypertension, primary small vasculitis, and the like has increased significantly. The annual incidence of end stage renal disease in the united states and europe is 336/million and 135/million, respectively. The prevalence rate of chronic kidney diseases in China is very high and accounts for 10% of the morbidity of the total population, the total number of the existing uremia patients in China is estimated to exceed 200 million, nearly 100 million patients depend on dialysis to maintain life, and newly discovered uremia cases account for about one part per million of the total population in China every year, and uremia is one of common diseases endangering human health.

The main treatment means of the end stage of chronic renal failure include three treatment modes of peritoneal dialysis, hemodialysis and kidney transplantation. Peritoneal dialysis is dialysis basically close to physiological state, does not affect living habits and social interaction of patients, is simple to operate and easy to carry out, can be carried out at home, and is particularly suitable for old patients, especially patients who have cardiovascular diseases or children or who have bleeding recently, unstable blood pressure and are inconvenient to hemodialysis at home in remote areas. Peritoneal dialysis is not only an effective treatment, but also an economical treatment, costing $ 71889 per year per hemodialysis patient in 2006 and $ 53327 per year per peritoneal dialysis patient according to the U.S. renal database (USRDS) report. Similar conditions in China, according to the research report of the insurance payment mechanism of the medical insurance division of the society for social insurance of China on dialysis treatment in 10 third-class hospitals and the like in six cities in China in 2005, the hemodialysis costs 10 ten thousand yuan per year, and the peritoneal dialysis is 78782 yuan. Therefore, peritoneal dialysis treatment is also a commonly used treatment from an economic perspective on the premise of ensuring the medical efficacy.

For a patient who depends on peritoneal dialysis to maintain life, the peritoneal dialysis tube is the life tube of the patient(s), in the actual clinical operation process, after the peritoneal dialysis is completed, one part of the peritoneal dialysis tube is exposed outside the patient, in order to prevent infection germs, an iodophor cap is screwed at the far end of a 9-inch extension short tube, but the external extension pipeline causes inconvenience to the daily life of the patient, the patient often considers the safety of the iodophor cap when moving the body, or the external extension pipeline is not fixed, can produce traction and friction on a fistulization opening, often causes infection, and affects the recovery of the patient.

Accordingly, those skilled in the art have endeavored to devise a peritoneal dialysis catheter extracorporeal fixation device for treating renal disease.
