Title:
BLOOD PURIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/073732
Kind Code:
A1
Abstract:
Provided is a blood purification device which is capable of accurately correcting the rotational speeds of a dialysate pump and a waste liquid pump, while reducing costs, by measuring the weight of a dialysate-accommodating bag and a waste liquid-accommodating bag using a single weighing scale, and which is capable of inhibiting errors in the flow rate of dialysate introduced into a blood purification means. This blood purification device is provided with a control unit 7 which is capable of controlling a dialysate pump P2 and a waste liquid pump P3 on the basis of the measurement value of a single weighing scale 4. The control unit 7 is capable of implementing a correction step in which the dialysate pump P2 is rotationally driven to make the dialysate in a dialysate-accommodating bag B1 flow without having to accommodate the dialysate in a waste liquid-accommodating bag B2, and the rotational speed of the dialysate pump P2 is corrected on the basis of the change in the measurement value of the weighing scale 4 while the dialysate is being made to flow.
