Patent ID: 11419968

Abstract:
An extracorporeal blood treatment apparatus comprises a blood treatment device (2), an extracorporeal blood circuit, a blood pump (8) configured to be coupled to a blood withdrawal line (6) of the extracorporeal blood circuit. A closed fluid line (10) is connected to an inlet port (4a) and to an outlet port (4b) of a fluid chamber (4) of the blood treatment device (2), wherein the closed fluid line (10) together with the fluid chamber (4) forms a recirculation loop. An evacuation line (15) departs from the closed fluid line (10). A warming device (13) and a recirculation pump (17) are coupled or configured to be coupled to the closed fluid line (10). At least one temperature sensor (22) is operative on the extracorporeal blood circuit and it is configured to sense a blood temperature (Tb). A control unit (25), connected to the warming device (13), to the recirculation pump (17) and to the temperature sensor (22), is configured to execute the following procedure: receiving from the temperature sensor (22) at least a signal correlated to the blood temperature (Tb); adjusting the blood temperature (Tb) by controlling at least one of the warming device (13) and the recirculation pump (17).
