摘要:
An electric heating blanket includes a flexible sheet-like heating element, a first unheated flap extending from a first edge of the heating element, and a second unheated flap extending from a second edge of the heating element. A flexible water-resistant shell may cover the heating element.
摘要:
An electric warming blanket includes a flexible heater that may be enclosed within a flexible shell, which is, preferably, water resistant and may extend beyond lateral edges of the heater to support stiffening members. A layer of non-conductive flexible porous material may be bonded to one or both sides of the heater. When the heater is enclosed in the shell, a layer of thermal insulation may be disposed between one side of the heater and the shell. A temperature sensor may be coupled to the heater at a location where the heater will be in conductive contact with a body when the blanket is draped thereover, and at least one super-over temperature sensor may also be coupled to the heater; the at least one super over-temperature sensor is adapted to interrupt a supply of power to the heater.
摘要:
A flexible heating subassembly, which may be incorporated in an electric warming blanket or any other type of flexible heater, includes a single heater, which is preferably formed from an electrically conductive polymeric fabric. The subassembly further includes first and second conductive bus bars, each extending alongside a respective first and second edge of the heater, each being coupled to the heater by at least one row of stitching that extends along the respective bus bar. The edges of the heater may be folded over respective bus bars for coupling and each of the bus bars may terminate just beyond opposing ends of the heater. A ribbon of conductive material may be interposed between each of the bus bars and the heater.
摘要:
A heating blanket cover is constructed from a lower sheet, which may include a first material layer laminated to a second material layer, and an upper sheet bonded to the lower sheet along a longitudinally extending bonding site, wherein the upper sheet extends laterally from the bonding site over the lower sheet to a free edge. The bonding site may be formed by heat sealing the upper sheet to the lower sheet. A gap between the upper sheet and the lower sheet forms an enclosure to hold the heating blanket; the enclosure is accessible by lifting the free edge of the upper sheet away from the lower sheet. A series of covers may be formed, for example by a web-manufacturing process, by bringing together at least two lengths of materials, bonding the lengths together and assembling the lengths on a roll for dispensing of individual covers from the series.
摘要:
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.
摘要:
An electric heating blanket system includes a flexible sheet-like heating element having a substantially uniform watt density output across a surface area thereof, when the heating element is electrically powered. A temperature sensor is coupled to the heating element at a location where the heating element will be in conductive contact with a body when the blanket is draped over the body. The system further includes a temperature controller coupled to the temperature sensor, and an electric power source coupled to the heating element and to the temperature controller, the power source being controlled to provide the watt density output for the heating element according to a temperature sensed by the sensor.
