Title:
HIGH-PRECISION PERISTALTIC PUMP FLOW RATE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/085155
Kind Code:
A1
Abstract:
A high-precision peristaltic pump flow rate control system, comprising a motor, a peristaltic pump, a rotational speed feedback assembly, a flow rate feedback assembly, and a controller. The motor is correspondingly connected to the peristaltic pump; the peristaltic pump is correspondingly connected to the rotational speed feedback assembly and the flow rate feedback assembly; the rotational speed feedback assembly and the flow rate feedback assembly are correspondingly connected to the controller; the controller is correspondingly connected to the motor. The flow rate feedback assembly comprises a flow rate measurement means and a determining module. By providing a flow rate feedback assembly to control the flow rate of an anticoagulation pump and the flow rate of a blood pump near set values, the precise control on the use amount of an anticoagulant for plasmapheresis is implemented, the quality of plasmapheresis, and the influence on the health of a plasma donor is reduced.
