Embodiment Construction

[0023] The present invention provides a patient warming device and method of use that can be used to maintain and provide heat to a patient to prevent hypothermia. A device incorporating the principles of the present invention can be used to provide heat to a patient.

[0024] Figure 1A shows a patient warming blanket 10 embodying one principle of the present invention. Patient warming blanket 10 includes insulating layer 12 , barrier layers 14 and 16 , porous pocket 24 containing thermal composition 26 , and thermal cushioning layer 20 .

[0025] The insulating layer 12 may be formed from many suitable materials or combinations of materials including, but not limited to, nonwoven and woven materials made from polymers such as polyester, polypropylene, polyethylene, polyparaphenylene Ethylene glycol dicarboxylate, polyamide, polyvinyl chloride, acrylic acid, acrylic copolymers, polystyrene, rayon, acetate, and polysulfone. In a preferred embodiment, the insulating layer 12 c...

Abstract

The present invention provides a patient warming device and method of application that may be used to retain and provide heat to a patient to prevent the onset of hypothermia.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Patent Application No. 60 / 640,384, filed December 30,2004. Background technique [0003] Patients under general anesthesia will experience several physiological changes that prevent the body's normal ability to regulate heat, such as depression of the thermal buffer center in the hypothalamus, infusion of intravenous fluids, and inhalation of dry anesthetic gases during surgery. Also, body cavities may be exposed during surgery. The incidence of hypothermia following surgery has been estimated to be as high as 60% to 90%. [0004] To prevent hypothermia, it may be necessary to provide heat to the patient during surgery. In one known device, the temperature of such a patient is controlled systemically using a soft blanket through which a temperature control fluid flows. However, most of the temperature exchange between the blanket and the patient occurs ...
