Abstract: A method for transfusing blood using a syringe pump is disclosed. The method includes connecting a blood supply line to an upstream connection of a check valve, an intravenous transfusion line to a downstream connection of the check valve, and a syringe pump to a second upstream connection of the check valve, and activating the syringe pump to automatically retract and drive a plunger of the syringe pump, repeatedly, according to a pump rate programmed into the syringe pump according to the automatic retracting and driving of the plunger. By this mechanism, a blood product is automatically withdrawn from the blood supply line, through the check valve, and into a chamber of a syringe loaded into the syringe pump during each cycle of the automatic retracting of the plunger, and provided through the intravenous transfusion line from the chamber during each cycle of the automatic driving of the plunger.
