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.

Blood purification device

A blood purification device includes a blood circuit for extracorporeally circulating blood of a patient: a blood purifier provided on the blood circuit; a gas-liquid separator being provided on the blood circuit on the downstream side of the blood purifier on a blood flow and separating air bubbles contained in inflowing blood: and a liquid level adjustment unit capable of adjusting a liquid level height in the gas-liquid separator. The liquid level adjustment unit performs control so that the liquid level height during priming is higher than the liquid level height during treatment.

A blood purification device includes a chamber, a liquid feed line, an air introduction unit, a liquid level adjustment unit, and a control unit. The chamber is provided on a blood circuit for extracorporeally circulating patient's blood and introduces purified plasma obtained by purifying plasma separated by a plasma separator provided on the blood circuit, or a replenishing liquid for replenishing the plasma separated by the plasma separator, into the blood circuit. The liquid feed line is capable of sending the purified plasma or the replenishing liquid to the chamber. The air introduction unit is capable of introducing air into the liquid feed line. The liquid level adjustment unit is capable of adjusting a liquid level height in the chamber. At the end of blood purification treatment, the control unit performs a liquid recovery process for sending the purified plasma or the replenishing liquid to the chamber via the liquid feed line while introducing air into the liquid feed line by the air introduction unit and maintains the liquid level height in the chamber at a predetermined liquid level height by the liquid level adjustment unit.

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 waste liquid circuit for discharging the waste liquid from the blood purifier. Each of the blood circuit, the liquid supply circuit and the waste liquid circuit comprises a flexible tube. The blood purification device comprises a tube identification unit that performs a tube identification process for identifying a tube used for the blood circuit, the liquid supply circuit or the waste liquid circuit or determining whether or not there is an abnormality in the tube, based on an amount of liquid sent from a peristaltic pump provided on the blood circuit, the liquid supply circuit or the waste liquid circuit, or pressure fluctuation in the circuit, caused when driving the pump for a predetermined time.
