Abstract

Provided is a blood purification device which is capable of rendering unnecessary a priming liquid recovery bag that is only connected during priming, and which is capable of reducing priming costs. This blood purification device enables priming to be performed by driving a blood pump (P1) to supply a priming liquid to a blood circuit (1). When discharging the priming liquid during priming, the blood purification device is capable of discharging, via a dialysate discharge line, the priming liquid supplied to the blood circuit (1), and is capable of discharging the priming liquid supplied to the blood circuit (1), by causing the priming liquid to flow to the dialysate discharge line (L2) via a liquid replenishment line (L3).

Description

Technical field [0001] The present invention relates to a blood purification device which is used to purify the blood of a patient while circulating it outside the body. Background technique [0002] Generally, a blood purification device used for dialysis treatment includes: an arterial blood circuit and a venous blood circuit constituting a blood circuit for extracorporeal circulation of the patient's blood; used to purify the blood that passes through the extracorporeal circulation of the blood circuit The blood purification mechanism; the device body, in which the device body is provided with various treatment mechanisms such as a blood pump for blood purification treatment through the blood circuit and the blood purification mechanism. A blood vessel contact probe or puncture needle (arterial side puncture needle and venous side puncture needle) can be installed at the front ends of the arterial blood circuit and the venous blood circuit respectively. [0003] In addition, fo...
