Technical Field
[0001] The utility model relates to the field of peritoneal dialysis, in particular to a liquid leakage detection device for an automatic peritoneal dialysis machine. Background Art
[0002] Peritoneal dialysis is one of the important means of treating end-stage renal disease. Its principle is to infuse peritoneal dialysis fluid into the abdominal cavity, using the human peritoneum as a semipermeable membrane to remove excess water, metabolites and toxins in the body, thereby purifying the blood and replacing the kidney's detoxification function. Peritoneal dialysis is divided into artificial peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD). Artificial peritoneal dialysis is performed manually by the patient, 4-5 times a day, each time for about 1 hour, which takes up a lot of the patient's time during the day, seriously affecting the quality of life, and the patient is prone to infection; automated peritoneal dialysis uses an automated peritoneal dialysis machine to achieve automated dialysis, and only requires a matching disposable sterile APD pipeline for treatment, which takes up the patient's sleep time at night to complete the treatment, allowing the patient to return to his family and society.
[0003] During peritoneal dialysis, peritoneal dialysis fluid flows out or leaks into the equipment, causing serious economic losses and safety hazards to patients. Therefore, leakage detection is required during unsupervised automatic peritoneal dialysis treatment, and a leakage detection device for an automatic peritoneal dialysis machine is needed. Currently, leakage detection mostly uses manual auxiliary detection methods, and there is no solution for leakage detection and early warning during automatic peritoneal dialysis. The utility model proposes a leakage detection device for an automatic peritoneal dialysis machine, which can continuously and dynamically detect and early warn leakage during peritoneal dialysis treatment to solve the problems existing in the prior art and ensure the safety of treatment.
