ABSTRACT:
An autotransfusion set includes a housing having a blood filtering and defoaming chamber connected to receive blood from a patient, and a blood reservoir connected to receive blood from the chamber and having an outlet for returning the blood to the patient, the blood normally being returned under pressure to increase the rate of infusion. A pressure relief valve is connected to the housing which has discrete, selectable pressure settings to limit the pressure within the chamber to a desired value. A float valve is disposed in the reservoir for closing it to the outlet when the blood level reaches a predetermined minimum level so as to preclude the infusion of air emboli to the patient, and for opening the reservoir to the outlet after the blood level has risen above the minimum level in order to reestablish infusion.
