Problems solved by technology
At present, the dialysate preparation adopts the traditional method of pump metering and dosing, which requires high accuracy and stability of the metering pump. The strong oxidant used in the cleaning and disinfection of the equipment corrodes the metering pump, which leads to the deterioration of the working performance of the whole machine. stability

The invention relates to a hemodialysis center liquid supply system which is used for medicine A and B to enter a hemodialysis machine. The hemodialysis center liquid supply system comprises a liquid supply device A, a liquid supply device B and a mixing device. The liquid supply device A and the liquid supply device B have the same composition. The liquid supply device A comprises a liquid storage unit, a weight control unit and a peristaltic pump. The liquid storage unit is used for storing medicine liquid A to be supplied. The weight control unit comprises a weight controller which receives the medicine liquid A and detects whether the weight of the medicine liquid A is proper. The peristaltic pump is connected with the weight controller through a pipeline and conveys the medicine liquid A according to the weight of the medicine liquid A detected by the weight controller. The mixing device is connected with the peristaltic pump and a peristaltic pump B of the liquid supply device B through pipelines, and medicine liquid conveyed by the peristaltic pump and the peristaltic pump B enters the mixing device for mixing. According to the hemodialysis center liquid supply system, the peristaltic pump is used as conveying power, performance is stable, and system stability is improved.
Description
technical field [0001] The invention relates to the field of medical hemodialysis, in particular to a liquid supply system for a hemodialysis center. Background technique [0002] The liquid supply system of the hemodialysis center is a kind of separation of the dialysate dosing device in the conventional hemodialysis machine from the hemodialysis machine, and the dialysate is prepared and supplied by the central liquid supply system, and the diluted dialysate is sent to the Each hemodialysis machine. This method reduces machine costs and saves working hours. At present, only Japanese JMS is produced at home and abroad. Due to the high price, it has not been used in China at present. Since the liquid supply system of the hemodialysis fluid center is used by multiple hemodialysis machines at the same time, the performance and stability of the equipment are particularly high. Because When the blood supply system of the hemodialysis fluid center breaks down, all the dialysis ...
