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).
