WORKING FLUID CASSETTE WITH HINGED PLENUM OR ENCLOSURE FOR INTERFACING HEAT EXCHANGER WITH INTRAVASCULAR TEMPERATURE MANAGEMENT CATHETER

摘要

An enclosure or plenum that supports a looped pump tube is hingedly connected to a framed thin-walled heat exchange bag through which working fluid from an intravascular heat exchange catheter flows. The frame with bag can be inserted between cold plates to exchange heat with the working fluid flowing through the bag. With the framed bag between the plates, the looped pump tube from the enclosure or plenum is receivable in the raceway of a peristaltic pump, which pumps working fluid through the system.

1. A device, comprising:
a thin-walled bag supported by a frame, the bag with frame being receivable between heat exchange plates such that heat can be exchanged between working fluid flowing through the bag and at least one of the heat exchange plates; and a plenum connected to the frame, the plenum supporting a pump tube in fluid communication with the bag, the pump tube being configured to engage a raceway of a pump so that the pump can urge against the pump tube to circulate working fluid.
