This invention is directed to apparatus and a method for monitoring the collection of blood from a donor so as to minimize trauma to the blood so collected. The system closely monitors the rate of collection of blood and regulates the rate of mixing of anticoagulant therewith so as to maintain a substantially constant ratio of anticoagulant to blood throughout the collection process. The system also includes built-in warning devices for indicating when the collection process is not proceeding according to a prescribed pattern.

Apparatus for monitoring the collection of blood from a donor into a plastic bag assembly which includes a blood collection bag, an anticoagulant supply bag, a first pliable tube interconnecting the two bags and a second pliable tube connected at one end to the blood collection bag and carrying a needle on its free end for insertion into a vein of the donor and comprising: a horizontal base; an upright support column mounted on said base; a control console disposed in a horizontal plane and mounted on top of said column; a first relatively fixed support for mounting the anticoagulant supply bag beneath said console; a second extendable support for mounting the blood collection bag beneath said console and being movable downward proportionately to the weight of blood and anticoagulant collected; a first manually actuatable hemostat means adapted to receive and restrict the flow of anticoagulant through the first tube; a second manually and electromagnetically actuatable hemostat means adapted to receive and restrict the flow of blood through the second tube; and electrical means effective to actuate said second hemostat means according to prescribed blood collection procedures.
