Abstract
A method of applying therapeutic heat, and a heat pack for providing therapeutic heat-transfer, are simple, inexpensive to use and practice, and readily re-usable. A piece of polyurethane foam wrapped by an absorbent material such as terry cloth or cotton batting, is saturated with water, placed in an inner nylon bag, and disposed in an envelope made of foam-lined flocked fabric, to form the pack. The pack is placed in a microwave oven to heat the water, and when removed is placed on a body part to be treated. The pack may be reheated and re-used, without opening, repeatedly. The outer covering is longer than the inner core, and can be folded-over to provide several thicknesses of insulation on one face of the pack, while the other face has a single thickness.
Claims8
A method of applying therapeutic heat to a mammal body part utilizing a heat pack including a liquid-absorbing inner core, a liquid-impervious microwave-transparent inner bag, and an outer microwave-transparent covering, comprising the steps of substantially sequentially:
- (a) applying liquid to the core so that it is substantially saturated;
- (b) disposing the core in the inner bag, and closing the bag;
- (c) disposing the closed inner bag and core in the outer covering;
- (d) disposing the heat pack in operative association with a microwave source to heat the liquid associated with the core;
- and
- (e) removing the heat pack from association with the microwave source and placing it in contact with a body part to be treated.
