Abstract

A patient warming device (400), which can be configured as a patient warming blanket (207), patient warming drape (300), or surgical drape (500), includes the top layer of material and optionally a bottom layer of material. The top layer (401) can be formed by laminating non-woven fabric (301) to a film layer (100) or by needle punching fibers through the film layer (100). The film layer (100) has a thermally reflective side (404) and a thermally absorptive side (405). The patient warming device (400) can be used in a patient warming system (700) with one or more light sources (701,702) and an optional control module (704) to warm a patient during and after medical procedures.
