Technical Field

The invention relates to the field of dialysis medical instruments, in particular to a sealed peritoneal dialysis device.

Background

Renal failure and renal hypofunction are treated by dialysis, which removes waste products, toxins and excess water from the body.

Hemodialysis and peritoneal dialysis are two common dialysis methods for treating renal dysfunction.

Peritoneal dialysis utilizes dialysate that is infused into the patient's peritoneal cavity. The dialysate contacts the peritoneum in the patient's peritoneal cavity, and waste, toxins and excess water pass from the patient's bloodstream across the peritoneum and into the dialysate. The transport of waste, toxins and water from the blood stream into the dialysate occurs due to diffusion and osmosis. The spent dialysate is drained from the patient's peritoneal cavity to remove waste, toxins and water from the patient and then replaced.

A peritoneal dialysis catheter is used to introduce fresh dialysate into the peritoneal cavity and drain used dialysate from the peritoneal cavity. Typically, peritoneal catheters are implanted into the peritoneal cavity and remain implanted in the body for a period of time.

Current peritoneal dialysis includes continuous outpatient peritoneal dialysis (CAPD) and automated peritoneal dialysis. CAPD is a manual dialysis treatment in which the patient connects an implanted catheter to a drain to allow spent dialysate to drain from the peritoneal cavity, then the patient connects the catheter to a fresh dialysate bag and manually introduces fresh dialysate into the patient's peritoneal cavity via the catheter. The patient separates the catheter from the fresh dialysate bag, leaving the dialysate resident in the peritoneal cavity, and the patient's blood stream transports waste, toxins, and excess water to the dialysate during the dwell period. After the dwell period, the patient repeats the manual dialysis procedure.

Within a day, the patient carries out the cycle of flowing back, filling and staying several times, and the manual peritoneal dialysis that the patient carried out needs patient's considerable time and energy, and peritonitis is produced to long-time peritoneal dialysis, and the peritoneum becomes the fibrosis, is unfavorable for the infiltration exchange of blood and dislysate, and peritoneal dialysis requires that the sanitation condition is high, and the population is ageing, and patient's operation is complicated, and the dialysis cycle is short, and is not convenient, and change dislysate bag causes export department, tunnel to appear infecting in daily peritoneal dialysis process.
