A process for the collection of blood from a body cavity requires a controllable flow conduit having an inlet and an outlet. The inlet of the conduit is placed in a body cavity from which blood is to be withdrawn. The outlet of the conduit is connected to the inlet of a blood collection apparatus. The apparatus includes an apparatus body having a first opening therein for connection to a source of suction and a gas-transmitting water seal. The apparatus also includes an autotransfusion collector for collecting and storing blood for optional blood reuse. The collector includes an outer receptacle and an inner receptacle. The inner receptacle includes at least one interior cavity and at least one substantially flexible wall at least partially enclosing the at least one interior cavity. The apparatus also includes a conduit for placing the source of suction in fluid communication with the interior cavity through the water seal. An inlet conduit communicates with the interior cavity and the body cavity for carrying blood to the inner receptacle when suction is applied to the first opening in the apparatus body. Preferably, the outer receptacle is substantially rigid and the collector further includes at least one intermediate cavity between the outer receptacle and the inner receptacle. In a preferred embodiment the intermediate cavity is sealed against fluid communication with the atmosphere.
