Abstract A system for autotransfusion has an aspirating wand or tube coupled to a vacuum source through a reservoir for receiving aspirated blood. From that reservoir blood flows to a receiving bag in a rela- tively low position below the elevation of the pa- tient. When there is sufficient blood supply in the bag, the bag is elevated from its lower position to a point higher that the patient. Blood then flows from the elevated bag by gravity through a conduc- ting tube and a needle into the patient. When the bag is then substantially empty, it is again lowered to an elevation lower than the patient for repeti- tion of the operation. If desired, an anticoagulant can be introduced into the aspirated blood.
