Abstract

The invention provides a valve state detection method. The valve state detection method comprises the following steps: opening an inlet end of a valve, closing an outlet end of the valve and inputting gas with rated pressure into the valve through the inlet end; determining an input state of the valve according to valve internal pressure detected by a sensor connected with the valve; when the input state of the valve is determined to be a normal state, closing the inlet end and opening the outlet end to exhaust the gas in the valve; determining an output state of the valve according to the valve internal pressure detected by the sensor. The valve state detection method has the following beneficial effects: the state of the valve for controlling fluid in peritoneal dialysis equipment can be detected, the performance of the valve is prevented from being degraded and thus the influences on the fluid control accuracy and the treatment effect are prevented.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a valve state detection method, a detection system and peritoneal dialysis equipment. Background technique [0002] The peritoneal dialysis technique is a variation similar to manual blood purification. It works by using the patient's well-supplied peritoneum as the body's own filter. The dialysate is infused into the patient's abdominal cavity through a catheter, and according to the principle of osmosis, urine components are removed from the blood and enter the abdominal cavity. After several hours, the dialysate carrying the urine component is then discharged from the peritoneal cavity, thereby realizing the effect of dialysis. [0003] In the prior art, peritoneal dialysis can generally be performed in several different ways. For example, with continuous ambulatory peritoneal dialysis (CAPD), patients themselves can change the dialysate manually, for example, 4 to 5 times ...
