Abstract

An extracorporeal blood treatment device (1) comprising a control unit (10) connectable to a blood warming device (200). The device (1) comprises: an extracorporeal blood circuit (100) and at least one infusion line (15, 21, 25) connected to the extracorporeal blood circuit (100). The control unit (10) is configured to perform the following procedure: receiving a signal indicating a desired blood temperature (T) at the end (70) of the blood return line (7) des ), the end (70) of the blood return line (7) is configured to be connected to the venous vascular access of the patient (P); at least to receive the infusion fluid in at least one infusion line (15, 21, 25) At least one flow rate (Q PBP , Q REP1 , Q REP2 ) related first signal; calculate the operating parameters (T OUT ;P w ) to maintain the desired blood temperature (T des ), the warming device (200) is configured to heat the blood heating region (H) of the extracorporeal blood circuit (100). The set point is calculated based on input parameters comprising: at least a first value representing a desired blood temperature (T des ); and at least one selected from the following group: the first signal (Q REP1 , Q PBP , Q REP2 ); and a second value representing the temperature (T REP1 , T PBP , T REP2 ).

Description

technical field

[0001] The invention relates to an extracorporeal treatment device for blood. According to certain aspects, an extracorporeal therapeutic device according to the invention incorporates or includes a blood warming device. The present invention also relates to a control method of a blood warming device, wherein the blood warming device may be a part of extracorporeal blood treatment equipment or may be an independent device communicating with extracorporeal blood treatment equipment. Background technique

[0002] Extracorporeal blood therapy involves removing blood from a patient, treating the blood outside the patient's body, and returning the treated blood to the patient. Extracorporeal blood therapy is commonly used to extract unwanted substances or molecules from a patient's blood and / or to add desired substances or molecules to the blood. Extracorporeal blood therapy is used in patients who cannot effectively remove substances from their blood, for examp...
