[0002] In hospital clinics, peritoneal dialysis is one of the renal replacement therapies, and is often used to treat acute renal failure, chronic renal failure, uremia, acute drug or toxic poisoning, and as an adjuvant treatment for liver failure to maintain the patient's normal life activities. Since peritoneal dialysis is based on the dialysis effect of the peritoneum to complete the exchange of plasma components and water in the patient's body to remove metabolic waste from the body, it is necessary to strictly control the waste fluid drainage volume and dialysate infusion volume during peritoneal dialysis to ensure the safety of patients during peritoneal dialysis.

[0003] At present, in clinical practice, manual measurement and monitoring is commonly used to monitor and measure the liquid flow during peritoneal dialysis treatment. Although this measurement and monitoring method can meet certain usage requirements, for peritoneal dialysis patients, especially peritoneal dialysis patients who have to repeat different prescriptions every day, the existing measurement and monitoring method has the problem of complex and cumbersome liquid flow measurement; in addition, during peritoneal dialysis treatment, it is often necessary to check the peritoneal dialysis status at any time to prevent medical accidents caused by the termination of peritoneal dialysis. With the existing measurement and monitoring method, since each peritoneal dialysis treatment is usually a long period of treatment, it is difficult to monitor the liquid circulation status in real time and issue timely warnings to prevent medical accidents through traditional measurement and monitoring methods, which is difficult to meet actual application needs.

[0004] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content

It also includes a controller electrically connected to the weighing sensor through a conductive wire for automatically measuring the weight data of the infusion liquid flow and the drainage liquid flow according to the collected weight information. A display screen electrically connected to the controller for displaying liquid weight data is embedded on the outer wall of the controller, wherein the liquid circulation warning structure is electrically connected to the controller.

[0009] Preferably, the liquid circulation warning structure includes an infrared sensor detachably mounted on the peritoneal dialysis fluid input end and the waste fluid output end of the external peritoneal dialysis circuit through a set of clamps for collecting liquid circulation information at the ends so as to monitor the liquid circulation status, and the infrared sensor is electrically connected to the controller through a conductive wire harness, and also includes a voice alarm disposed on the top of the controller and electrically connected to the controller for issuing a warning signal when the peritoneal dialysis fluid input end or the waste fluid output end of the external peritoneal dialysis circuit is disconnected to remind medical staff to control the peritoneal dialysis operation in time.
