ABSTRACT:
The present invention is directed to a self-contained, totally disposable apparatus for the collection and reinfusion of blood which is suitable for use with a chest drainage unit to provide for the autotransfusion of autologous blood and the method of suing the apparatus. The blood collection and reinfusion apparatus is separate in structure from the chest drainage unit and comprises a rigid outer container and an inner flexible container in conjunction with portals for blood collection, reinfusion, and attachment to a vacuum source. The apparatus and method of the invention provides a closed system, requires minimal handling of the blood, and provides for greater patient safety in that no interruption of the operation of the chest drainage unit is required.
