Embodiments include a heating blanket. The heating blanket may include a heating element and a shell covering the heating element. The heating element has elastic properties and is disposed in the shape of a sheet. The shell may have one or more sheets of polymeric material bonded together adjacent a perimeter of the heating element. One or more wires having malleable properties are secured within the shell. The wires allow the heating blanket to be secured to a patient.

A heated underbody support comprising a heated mattress, heated mattress overlay or heated pad. The heated underbody support includes a heater assembly having an upper surface upon which a user directly or indirectly lays when the heated underbody support is in use. The heater assembly includes a flexible heating element including a sheet of conductive fabric having a substantially uniform Watt density. The heated underbody support also includes a layer of compressible material adapted to conform to the user's body when under pressure from the user resting upon the support. When the user lays upon the upper surface of the support, the heating element is adapted to adjust such that the temperature of the contact portion is less than the temperature of the non-contact portion of the support.
A multi-zone electric heating blanket. The blanket may be shaped to cover the outstretched arms or other body parts of a patient. The blanket includes first and second body part portions and a connecting bridge. The interconnection via the bridge leaves an open gap between the first and second body part portions for unblocked access to the patient. A power controller may supply power to heating elements in both body part portions based on a temperature sensor in one of the body part portions.

A blanket for warming patients during surgery and other medical procedures. The blanket includes one or more temperature sensors and a shut-off timer to prevent prolonged exposure of excessive heat to a patient. Embodiments of the present invention provide a safety feature that cuts power to a heating blanket after a certain period of time has elapsed, irrespective of the feedback provided by a temperature sensor concerning the blanket temperature. That period of time is longer than it takes for the blanket to reach its threshold temperature but shorter than it takes to cause thermal burn injury.
Embodiments of the present invention provide a heating blanket that can be secured to the head and at least one arm of a patient while leaving the patient's chest and abdomen remain substantially exposed. The head and arms tend to be excellent heat exchange surfaces. These surfaces can also be relatively large for heating purposes. Thus, many embodiments are able to warm patients effectively while leaving the chest and abdomen exposed and unobstructed, thereby providing enhanced access for caregivers in surgery and/or observation.
Medical apparatus comprising patient and clinician body temperature management products, namely, electrically activated warming systems that primarily consist of an electrical heating source, a cover for a portion of the body and controls therefor
A cover includes an enclosure for a heating blanket which is formed between an upper sheet bonded to a lower sheet of the cover. An opening for the enclosure is formed by a panel of the upper sheet which is separable from the lower sheet.
A flexible heating subassembly, that may be incorporated in a heating blanket or any other type of flexible heater, includes a flexible sheet-like heating element, or heater, to which first and second conductive bus bars are coupled, each with a respective first and second row of conductive stitching. A first electrically insulating member is interposed between the first bus bar and the heater and is secured therebetween by the first row of stitching, and a second electrically insulating member is interposed between the second bus bar and the heater and is secured therebetween by the second row of stitching. The first and second insulating members prevent direct electrical contact between respective first and second bus bars and the heater.
