Blood purification device

Abstract

A blood purification device includes a blood circuit for extracorporeally circulating blood of a patient; a liquid supply circuit for supplying a supply liquid to the blood circuit or to a blood purifier provided on the blood circuit and a warmer provided on the liquid supply circuit to warm the supply liquid. The warmer is configured to sandwich and hold a warming circuit constituting a part of the liquid supply circuit. The warmer includes a heater provided on a sandwiching-and-holding surface sandwiching and holding the warming circuit. The warmer includes a heater temperature detection unit capable of detecting temperature of the heater. The warmer includes a temperature sensor for liquid temperature detection being capable of detecting temperature of the supply liquid flowing through the warming circuit and being provided on the sandwiching-and-holding surface at a position at which the temperature sensor for liquid temperature detection is separated from the heater and, when sandwiching and holding the warming circuit, comes into contact with the warming circuit on the downstream side of a portion warmed by the heater in a direction of sending liquid.
