ABSTRACT:
A portable stethoscope warming device incorporating an exothermic reaction heating element and adapted to be used with both diaphragm type and bell type stethoscopes. The device generally comprises a pouch member having a first pocket and a second pocket formed therein. The first pocket is adapted to receive either a diaphragm member or the bell member of conventionally known bell and diaphragm type stethoscopes. The second pocket is adapted to receive a heating element which comprises a packet having a bulkhead therein which, when ruptured, allows chemicals contained within the packet to mix in a manner producing a prolonged exothermic reaction. The second pocket is disposed directly adjacent the first pocket such that the heating packet is operable to warm the skin contacting surface of the diaphragm or bell member of the stethoscope.
