Abstract
A movable blood aspiration wand, especially for use in autotransfusion, carries with it a tank for anticoagulant replenished from an anticoagulant source fixed at a high source and is connected to a blood reservoir at a low elevation. Differences in wand height relative to the source and to the blood reservoir are compensated for, so that differences in wand height and corresponding blood and anticoagulant head do not substantially vary the anticoagulant proportion added to the aspirated blood.
