A new design for a plastic microvascular clamp is described. The clamp consists of two flat blades, with eyes permitting application and removal of the clamp with cross-forceps. Closure is effected by the elasticity of a rubber ring placed around the blades, obviating the need for an articular joint or a spring mechanism. The new design simplifies production of the clamp, which is intended to be disposable, i.e., for once-only use.
The disposable device for intraoperative reinfusion consists of a polycarbonate container with an antifoam-coated filter. One port is connected to the suction tip; the other port is attached to wall suction. Sodium citrate solution (50 to 100 ml) is aspirated first, followed by 400 ml of shed blood. The full container is passed to the anesthetist who turns the device upside down and starts reinfusion from the bottom, previously the top port of the container. In experiments with dogs, this procedure resulted in only slight hemolysis, a minor drop in platelet count, and no mortality or morbidity. This new method of reinfusion combines the advantages of simplicity, disposable equipment, and low blood trauma.
