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 relatively low position below the elevation of the patient. When there is sufficient blood supply in the bag, the bag is elevated from its lower position to a point higher than the patient. Blood then flows from the elevated bag by gravity through a conducting 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 repetition of the operation. If desired, an anticoagulant can be introduced into the aspirated blood.
