A new method for autotransfusion of shed blood.
A new autotransfusion device for collection and retransfusion of whole blood is described. The construction, function and possible advantages of the system compared with currently available systems are discussed. The system is built up around a hollow fibre haemoconcentrator (dialysis filter), a cardiotomy reservoir and a large volume infusion bag. To prevent clotting, citrate (ACD-solution) is added in the suction tubing as well as locally. The blood is driven through the system by a roller pump.
