Abstract
An oxygenator includes a housing having a blood inlet and a blood outlet, the blood inlet extending into an interior of the housing. A heat exchanger is disposed within the housing, and is coupled, at an inlet end, to a heat-exchange fluid inlet. A gas exchanger also is disposed within the housing, and includes a bundle of gas-exchange fibers coupled, at a gas outlet end, to a gas-exchange fluid outlet. The oxygenator includes at least one insulator configured to thermally insulate at least the gas outlet end of the bundle of gas-exchange fibers.
Claims20
An oxygenator configured to oxygenate blood flowing therethrough, the oxygenator comprising:
- a housing having a blood inlet and a blood outlet, the blood inlet and the blood outlet in fluid communication with an interior of the housing;
- a heat exchanger disposed within the housing, the heat exchanger including a heat-exchange fluid inlet, a heat-exchange fluid outlet, and a bundle of gas-exchange fibers through which a heat-exchange fluid is configured to flow from a fluid inlet end of the bundle of heat-exchange fibers to a fluid outlet end of the bundle of heat-exchange fibers;
- a gas exchanger disposed within the housing, the gas exchanger including a gas-exchange fluid inlet, a gas-exchange fluid outlet, and a bundle of gas-exchange fibers through which a gas-exchange fluid is configured to flow from a gas inlet end of the bundle of gas-exchange fibers to a gas outlet end of the bundle of gas-exchange fibers;
- and
- an insulating chamber configured to receive an insulating fluid to thermally insulate at least the gas outlet end of the bundle of gas-exchange fibers proximate the gas-exchange fluid outlet.
