ABSTRACT:
An autotransfusion bag is provided with semi-rigid side walls and flexible material interconnecting the side walls. The bag is provided with spreader arms which extend across the top of the bag and across the bottom of the bag engaging retainer elements mounted on the external face of the side walls. The spreader arms maintain the bag in an open position to permit the bag to be filled with blood. When the bag is filled, the spreader arms may be removed to permit the bag to collapse as the blood is being reinfused to the patient.
