Title:
HEMODIALYSIS DEVICE AND SUPPLEMENTAL LIQUID LINE CONNECTION STATE DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/138151
Kind Code:
A1
Abstract:
Provided are a hemodialysis device and a supplemental liquid line connection state detection method that can accurately detect the attachment state of a supplemental liquid clamp for opening-closing a supplemental liquid line. The hemodialysis device 100 comprises a blood circuit 110, a dialysate circuit 130, a supplemental liquid line 140, a supplemental liquid pump 140a, a supplemental liquid clamp 140b, a pressure sensor 140c measuring the liquid pressure in the supplemental liquid line 140, a control unit 161, and a determination unit 162, wherein the control unit 161 activates the supplemental liquid pump 140a, causing the liquid pressure of the supplemental liquid line 140 to rise, and the determination unit 162 determines that the supplemental liquid line 140 is connected correctly if the measured liquid pressure in the supplemental liquid line 140 is at a predetermined value or higher, and determines that the supplemental liquid line 140 is not connected correctly if the measured liquid pressure is smaller than the predetermined value.
