Blood oxygenator in combination with a low pressure heat exchanger
Abstract
Abstract A BLOOD OXYGENATOR HAS A THIN WALL HEAT EXCHANGER SHELL, HAVING A HIGHLY THERMALLY CONDUCTIVE SHELL WALL COMPOSITION, COAXIALLY ETERIORLY DISPOSED AROUND A BLOOD OXYGEN EXCHANGE TUBULAR ARRAY. THE APEX OF THE SHELL IS TIGHTLY SEALED TO THE TOP TERMINUS OF THE TUBULAR ARRAY AND THE BASE OF THE SHELL IS TIGHTLY SEALED TO AN EXTERIORLY DISPOSED COAXIAL OXYGENATED BLOOD COLLECTOR MANIFOLD. THE INTERIOR FACE OF THE SHELL WALL ADJACENT TO THE TUBULAR ARRAY IS PROVIDED WITH A FLOWING THIN FILM HEAT TRANSFER FLUID FROM A HEAT TRANSFER FLUID CIRCULATORY MEMBER HAVING A FLUID INLET AND MULTIPLE FLUID OUTLETS. THE HEAT TRANSFER FLUID EXCHANGES THERMAL ENERGY WITH THE OXYGENATED BLOOD FLOWING DOWN THE NARROW ANNULAR VOLUME DISPOSED ON THE EXTERIOR OF THE HEAT TRANSFER SHELL.
