ABSTRACT:
An apparatus for warming flowing blood from storage to physiologic temperatures at transfusion rates up to 160 milliliters per minute includes a flat metal cartridge formed by a pair of thin generally rectangular planar members spaced slightly apart in parallelism and sealed at their peripheral edges to define a thin unobstructed, constant-width and uniform thickness ribbon-like conduit through which the blood flows from an inlet port to an outlet port at opposite ends of the cartridge. An inlet chamber and an outlet chamber, each defined by an elongated recess in one of the planar members, communicates the entire width of a corresponding end of the conduit with the inlet and outlet ports to establish uniform blood flow across the full conduit width. The cartridge is clamped between a pair of thick metal buffer blocks which dampen fluctuations in the flow of heat to the planar members of the cartridge from electric resistance heaters located on the opposite side of each buffer block.
