METHOD AND DEVICE FOR DETERMINING STATE OF CONNECTION OF LIQUID REPLENISHING LINE TO BLOOD CIRCUIT IN HEMODIALYSIS DEVICE

摘要

The objective of the present invention is to provide a determining method and a determining device which enable easy determination of a state of connection of a liquid replenishing line to a blood circuit in a hemodialysis device. This method for determining the state of connection of a liquid replenishing line 140 to a blood circuit 110A in a hemodialysis device 100A comprises: a pump operating step of causing a blood pump 111a and a replacement fluid pump 140a to operate in the blood circuit 110A in a state in which one end side of an artery side line 111 and one end side of a vein side line 112 are connected to one another and the blood circuit 110A is not full of liquid; a bubble detecting step of detecting bubbles by means of a bubble detector 111b (112b) in a state in which a preset first time has elapsed after the blood pump 111a and the replacement fluid pump 140a were operated; and a determining step of determining whether the liquid replenishing line 140 is connected to the artery side line 111 or is connected to the vein side line 112 in accordance with whether or not bubbles are detected.
