A heating pad comprising:
- a heating pad member comprising a cover and electrical heating coils, said cover comprising a first layer and a second layer, said first layer being an inner layer, and said second layer being an outer layer, each layer comprising a flexible fabric material and having a plurality of sides being permanently secured together, wherein the electrical heating coils are enclosed by the cover and substantially evenly distributed therewithin;
- and
- a removable gel pack member having an outer surface for contacting an anatomical portion of a subject, said removable gel pack member being releasably attached to said first layer of the cover of the heating pad member and comprising a heat-retentive gel which is heated to a predetermined temperature prior to attachment to the first layer of the cover of the heating pad member, wherein said pre-determined temperature is substantially maintained during application to the subject after said attachment by operating the electrical heating coils.
A heating pad comprising:
- a substantially planar heating pad member comprising a cover and, electrical heating coils, said cover comprising a first layer and a second layer, said first layer being an inner layer, and said second layer being an outer layer, each layer comprising a flexible fabric material and having a plurality of sides being permanently secured together, wherein the electrical heating coils are enclosed by the cover and substantially evenly distributed therewithin;
- and
- a substantially planar removable gel pack member having an outer surface directly contacting an anatomical portion of a subject, said removable gel pack member being releasably attached to said first layer of the cover of the heating pad member and comprising a heat-retentive gel which is heated to a predetermined temperature prior to attachment to the first layer of the cover of the heating pad member, wherein said pre-determined temperature is substantially maintained during application to the subject after said attachment by operating the electrical heating coils.
