Title:
BLOOD PURIFICATION DEVICE AND METHOD FOR CONTROLLING LIQUID FEED PUMP
Document Type and Number:
WIPO Patent Application WO/2024/005066
Kind Code:
A1
Abstract:
The present invention comprises: a dialysate circuit 41 including a blood circuit 21, a dialysate feed channel 52, a dialysate discharge channel 53, and a bypass channel 54; a pressurization pump 73 installed on the dialysate circuit 41; and a main control unit 22 for controlling driving of the pressure pump 73. When a pressure difference is produced between the blood circuit 21 and the dialysate circuit 41 in instances where a switch is made from a bypass liquid feed mode in which liquid is fed from the dialysate feed channel 52 to the dialysate discharge channel 53 via the bypass channel 54 to a main liquid feed mode in which liquid is fed from the dialysate feed channel 52 to the dialysate discharge channel 53 via a dialyzer 10, the main control unit 22 adjusts the pump speed of the pressurization pump 73 so as to reduce the pressure difference.
