摘要： A dual lumen coaxial cannula assembly includes a first infusion tube having a first elongate body defining a first lumen therethrough, the first infusion tube having a proximal end, a distal end, and a sidewall extending circumferentially therebetween. A second drainage tube is co-axially aligned with the first infusion tube and has a second elongate body with a second lumen defined by a space between the first infusion tube and the second drainage tube. The second drainage tube has a proximal end, a distal end, and a sidewall extending circumferentially therebetween. A connector is attached to the proximal end of the first infusion tube and the proximal end on the second drainage tube. The cannula assembly further includes a distal tip connected to the distal end of the first elongate body and made of a material having a lower hardness than a hardness of the first elongate body.

摘要： An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patient's blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters. A controller is operatively coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.
