ABSTRACT:
An integral blood oxygenator and heat exchanger device for oxygenating and heating or cooling a patient's blood during heart bypass surgery. The device preferably includes a pleated blood filter disposed within a gap formed between the opposite ends of the blood oxygenating medium. A blood inlet manifold closely receives a tubular heat exchanging barrier and directs blood flow around the barrier to a blood outlet slot. The blood oxygenating medium covers the blood outlet slot so that blood must flow through the blood oxygenating medium before reaching the blood filter. A vent port and bypass port may be provided in the gap formed by the opposite ends of the blood oxygenating medium upstream of the blood filter.
