Title:
HEMODIALYSIS APPARATUS AND CONNECTION STATE DETECTION METHOD OF REPLENISHMENT LIQUID LINE
Document Type and Number:
Japanese Patent JP2020099584
Kind Code:
A
Abstract:
To provide a hemodialysis apparatus and a connection state detection method of a replenishment liquid line that can accurately detect a mounting state of a replenishment liquid clamp for opening/closing the replenishment liquid line.SOLUTION: A hemodialysis apparatus 100 includes a blood circuit 110, a dialysis liquid circuit 130, a replenishment liquid line 140, a replenishment liquid pump 140a, a replenishment liquid clamp 140b, a pressure sensor 140c for measuring liquid pressure of the replenishment liquid line 140, a control unit 161, and a determination unit 162. The control unit 161 actuates the replenishment liquid pump 140a and increases the liquid pressure of the replenishment liquid line 140. The determination unit 162 determines that the replenishment liquid line 140 is correctly connected when the measured liquid pressure of the replenishment liquid line 140 is a predetermined value or more, and determines that the replenishment liquid line 140 is not correctly connected when the measured liquid pressure is less than the predetermined value.SELECTED DRAWING: Figure 5
