Patent number: 7232457Abstract: A fluid warming cassette for use in a fluid warming system includes a first sheet and second sheet joined with a flexed tensioning rod to form a fluid container with a periphery in which the flexed tensioning rod is disposed to tension the fluid container. The fluid container includes a fluid channel with inlet and outlet ports in fluid communication with the fluid channel. Preferably, the rod is flexed into an open-ended shape such as a “U” shape. So flexed, the rod tensions the fluid container, adding structural stability to the fluid warming cassette.Type: GrantFiled: August 8, 2002Date of Patent: June 19, 2007Assignee: Arizant Healthcare Inc.Inventors: Wayne Eugene Schmidt, Scott Allen Entenman

Patent number: 7195056Abstract: A heat transfer cover mitigates temperature changes of an object. A cover body is configured to receive the object. A plurality of heat transfer channels are defined in an interior of the cover body. The channels are arranged to transport a heat transfer fluid in thermal communication with the object. An inlet port is configured to connect the plurality of channels with a source of the heat transfer fluid. An interior surface of the cover body may substantially conform to a shape of an exterior of the object. A plurality of lands may be defined in the interior of the cover body. The lands are arranged to engage the exterior of the object. The heat transfer channels may be defined between adjacent lands. At least a first end of the cover body may define an opening. The at least first end and the object are substantially sealed at the opening.Type: GrantFiled: June 29, 2004Date of Patent: March 27, 2007Assignee: The Boeing CompanyInventors: Joseph M.
