20080230530 | HEATING BLANKET - An electric heating blanket including a flexible sheet-like heating element and a shell. The shell covers the heating blanket an includes two sheets of flexible material welded together. | 09-25-2008 |
20090099631 | MULTI-ZONE ELECTRIC WARMING BLANKET - 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. | 04-16-2009 |
20100161016 | APPARATUS AND METHOD FOR EFFECTIVELY WARMING A PATIENT - A patient warming blanket includes a pouch and a flexible heating assembly. The flexible heating assembly is enclosed within the pouch and includes, at least in part, a flexible sheet-like heater and a temperature sensor assembly attached to the heater in proximity to a surface thereof; a visible marker is located on an exterior of the pouch to identify a location of the temperature sensor. A method for covering a patient with the patient warming blanket, in order to effectively warm the patient, includes viewing the marker so as to position an area of the blanket, which corresponds to the sensor location, for direct contact with the patient, when the blanket is placed over the patient. | 06-24-2010 |
20120279953 | HEATED UNDER-BODY WARMING SYSTEMS - A heated underbody supports including heated mattresses, heated mattress overlays and heated pads, and methods of using heated underbody supports, for therapeutic warming. The heated underbody supports include a heater assembly and a layer of compressible support material. The heater assembly includes a flexible heating element , first and second bus bars, and a temperature sensor. The flexible heating element is a conductive fabric which can be adapted to stretch into a 3-dimensional compound curve without wrinkling or folding while maintain electrical conductivity, and wherein the heating element is adapted to return to the planar shape when pressure is removed. The flexible heating element may include a fabric which is coated with a conductive or semi-conductive polymer. The heated underbody support may also include a water resistant shell which may encase the heater assembly and the compressible support material. | 11-08-2012 |
20120312797 | HEATING BLANKET - An electric heating blanket including a flexible sheet-like heating element and a shell. The shell covers the heating blanket and includes two sheets of flexible material welded together. | 12-13-2012 |
20140263265 | HEATING BLANKET - An electric blanket including a flexible sheet-like heating element, a shell comprising two flexible sheets covering the heating element, one or more welds coupling the sheet of the shell about the edges to hermetically seal the heating element there between; and a flexible insulating layer extending over the heating element and covered by the shell providing at least one of thermal insulation and electrical insulation, wherein the heating element is held in position between the two sheets of the shell without using connectors that pierce the two sheets. | 09-18-2014 |
20150148874 | MULTI-ZONE ELECTRIC WARMING BLANKET - 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. | 05-28-2015 |
20150327332 | ELECTRIC HEATING BLANKET OR PAD - An electric blanket or pad for warming a living body including a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges. A shell formed of layers of flexible sheets covering the heating element and sealed with a weld. The weld coupling the sheets of the shell about the edges to hermetically seal the heating element therebetween. The weld may be an RF weld, ultrasonic weld, or a heat bond, wherein the sheets comprise PVC. | 11-12-2015 |
