ABSTRACT:
An autologous blood system comprising at least two interconnected blood receptacles, the first of which is evacuated and connected to a suction device for aspirating blood. The second receptacle takes blood from the first by overcoming the vacuum in the first without interrupting the ability of the suction device to simultaneously aspirate blood. An infusion set is connected to the second receptacle to permit simultaneous collection of the blood from the patient and infusion of the blood back into the patient. The method includes aspirating blood from the patient and collecting blood in the first receptacle. Blood is thereafter transferred to the second receptacle by overcoming the vacuum in the first receptacle without interrupting the ability of the suction device to simultaneously aspirate blood. Blood is then returned to the patient either with or without disconnecting the second receptacle from the first, the infusion step taking place concurrently with blood collection.
