ABSTRACT:
Apparatus for the rapid infusion of physiologic solutions into the human body which have been warmed by said apparatus to normothermic temperature. The apparatus includes an extracorporeal heat exchanger which warms cold bank blood and other physiologic solutions to normothermic temperature. Bank blood and blood products enter the apparatus through a filtered infusion line. Crystalloids and synthetic colloids enter the apparatus through an unfiltered infusion line. Bank blood, blood products, crystalloids, and synthetic colloids flow through PVC tubing, filtered drip chambers, and the extracorporeal heat exchanger at a rapid rate to restore and maintain the normal circulating blood volume of a patient in hypovolemic shock. The flow rate is regulated by PVC tube clamps and a fluid shut-off valve. The apparatus also embodies a macrodrip administration set for the infusion of drugs and other physiologic solutions at a slower infusion rate. Normothermic physiologic solutions are infused into the patient's central venous blood pathway through a large-bore vein catheter.
