載の血液回路プライミング装置。[Claims for Utility Model Registration] (1) In a blood circuit in which a fluid replacement line AL is connected to the arterial circuit 3 side of a dialyzer DL equipped with arteriovenous circuits 3 and 4, the arteriovenous side of the dialyzer DL. Suction pumps P1 and P2 are connected to the arteriovenous chambers AT and VT provided in the main body, respectively, and electric valves V1 are connected to the outer circuits of the arteriovenous chambers AT and VT, respectively.
, V2 are provided, and by closing the electric valves V1 and V2 and evacuating each of the suction pumps P1 and P2, the blood passage side in the dialyzer DL is made negative pressure, and the dialysate passage side in the dialyzer DL is filled. After sucking out the liquid to the blood passage side through the permeable membrane, when this filling liquid reaches a level L2 near the lower end of the arterial chamber AT, the arterial side suction pump P1 and the venous side suction pump P2 are stopped. The liquid level in AT rises due to the residual negative pressure between both chambers AT and VT and reaches the inner bottom of the arterial chamber AT.Then, by opening the electric valve V1 and evacuating the arterial side suction pump P1, the fluid replacement line is removed. A blood circuit priming device characterized in that the arterial chamber AT is filled with replacement fluid from the AL to a predetermined chamber level L1. (2) The blood circuit priming device according to claim 1, characterized in that the arterial side suction pump P1 is equipped with a pressure sensor that limits its working pressure. (3) Activate the arterial and venous suction pumps P1 and P2 to supply fluid from the fluid replacement line AL connection port to the specified arterial chamber level L1 and venous chamber level L.
2, open the motorized valves V1 and V2 to discharge fluid from the venous puncture needle connection port 10b, and then open the motorized valve V3 provided between the arterial puncture needle connection port 10a to discharge replacement fluid. Arterial side puncture needle connection port 10a
2. The blood circuit priming device according to claim 1, wherein the blood circuit priming device discharges blood into the blood circuit for a specified time.
