Abstract

A device and method for providing heat transfer fluid to a medical heat exchanger (42) including warm (16) and cold (14) transfer fluid reservoirs for holding transfer fluid (38) at atmospheric pressure connected to a rotary vane positive displacement fluid supply pump (18) and heat exchanger. The heat transfer fluid is provided to the heat exchanger below atmospheric pressure and a pressure lower than the controlled fluid, such as cardioplegia fluid. The pump is downstream of the heat exchanger, draws the heat transfer fluid from the heat exchanger and recirculates the heat transfer fluid back to the reservoirs. The device may include a heat transfer fluid recirculation control system (200 that switches between warm and cold heat transfer fluid and returns the heat transfer fluid to the originating reservoir by delaying the switch of the return valve (24). The switching may be delayed by an adjustable temperature or time delay.
