Apparatus for warming medical pads
First Claim
1. A medical application holding system comprising:
- (a) a case having at least side walls and a bottom forming an enclosure (b) means for heating the medical application pads within the case, (c) means for controlling the temperature and holding it within a predetermined range within said case, (d) a removable lid to completely close said case and to retain heat within said case while providing access to the medial application pads contained within said case, said wall being thermally insulated to retain heat within said enclosure, said means for heating a heating element, said heating element is electrical and includes means for receiving electrical power and wherein said means for controlling the temperature range within said case includes a thermostat connected to sense the temperature within the case and to modify the electrical power supplied to the electrical heating element to maintain said predetermined range of temperature within said case, and (e) a plurality of individual removable compartments contains within said enclosure each said compartments being capable of holding medical application pads.

Abstract
An insulated case designed to keep medical pads warm and in a condition ready for application over a period of hours. The case typically includes a cover, multiple internal containers and a source of controlled heat to warm the pads. The pads, after being saturated with a medication such as alcohol, are stored in the internal containers where they are raised in temperature by the controlled heat source to a predetermined temperature range and maintain within that temperature range. At the same time, the vapor pressure is maintained at a level within the internal containers to prevent the escape of the alcohol from the pads through evaporation. The safety features of this apparatus include an over temperature alarm and automatic shut off as well as an over pressure alarm and vent, all of which operate even when there is a power failure. Internal containers are individually insulated and are removable for transport to wherever they are needed. Each internal container includes a temperature sensing device which indicates whether the pads are still within the desired temperature range after they have been removed from the source of controlled heat.
