Description

Peritoneal dialysis waste liquid drainage detection device Technical Field The invention relates to the technical field of peritoneal dialysis, in particular to a peritoneal dialysis waste liquid drainage detection device. Background Peritoneal dialysis is a kidney replacement therapy that utilizes the human own peritoneum as a semipermeable membrane. The core principle is that the biocompatible dialysate is infused into the abdominal cavity through the indwelling catheter. At this point, excess water and metabolic waste products (e.g., creatinine, urea) in the blood will pass through the peritoneal capillaries into the dialysate by virtue of the concentration gradient differences. After a few hours of "abdominal" exchange, the waste liquid rich in waste is drained out of the body, thereby simulating the filtration function of the kidney. In automated peritoneal dialysis treatment, a portion of patients select a nocturnal mode. The posture change during sleeping can cause the drainage hose to be pressed, folded or deformed, thereby causing unsmooth drainage, abnormal flow and even treatment interruption. The traditional monitoring mode relying on preset time cannot identify the sudden mechanical obstruction in time, so an intelligent device capable of accurately monitoring the drainage state in real time is needed. Disclosure of Invention The invention aims to solve the problems and provides a peritoneal dialysis waste liquid drainage detection device.
