Title: Inflatable thermal blanket with a multilayer sheet

Abstract: An inflatable thermal blanket with a multilayer sheet and a method of use are disclosed for delivering thermally-controlled air to a person. The apparatus includes an inflatable structure formed from joining a first sheet and a second sheet. An inlet is provided into the inflatable structure for receiving thermally-controlled air. A multilayer sheet, made from a plurality of sheets releasably attached together, is attached to the second sheet. Means are provided for exhausting the thermally-controlled air from the inflatable thermal blanket. In the method of use, the inflatable thermal blanket is deployed in a first use and a source of thermally-controlled air is attached to the inflation port admitting thermally-controlled air into the inflatable structure and exhausting thermally-controlled air. Additionally, the inflatable thermal blanket may be reused by detaching the lowest layer of the multilayer sheet, exposing another layer of the multilayer sheet and deploying the inflatable thermal blanket in a second or later use. These steps may be repeated until the last layer of the multilayer sheet is used, when the thermal blanket may be discarded. In an alternate embodiment, when the multilayer sheet is exhausted it is detached and another multilayer base sheet is attached to the inflatable structure and the thermal blanket is used again.
