Abstract
A portable therapeutic heating device is provided that may be readily worn and transported by a user. A flexible heating unit is attached to a body part and is capable of raising the skin temperature of that body part to about 102.degree.-108.degree. F. The flexible heating unit includes a plurality of distinct sets of electric resistance heating elements. The flexible heating unit is connected by a flexible tape to a battery pack which is mounted to the approximate center of gravity of the user's body. A switch is mounted on the battery pack, and provides for selection of which sets of electric resistance heating elements will be energized by a battery received by the battery pack, to thereby vary the amount of heat applied by the heating unit to a body part. The switch is mounted in a cutout formed in a casing defining the battery pack. A pair of rechargeable lead-acid "D" batteries are desirably received by the battery pack, and circuitry is provided for indicating when the voltage of a rechargeable battery received by the battery pack reaches a predetermined value below the rated value of the battery. A printed circuit board is mounted completely covering the batteries in the b…
