Abstract:
A method for fabricating a stethoscope comprising:providing a substrate, the substrate being a first employed within a stethoscope, the substrate having a surface to handling; forming upon the first surface of handling a coating a formed from a foamed polymer material, the foamed polymer material having a density of from about 0.05 to about 1.2 grams per cubic centimeter, a thermal conductivity of from about 0.02 to about 0.15 watts per meter-degree centigrade and a thickness of from about 0.1 to about 3 millimeters, such that when the substrate having the coating formed thereupon is equilibrated at a non-body temperature differing from a body temperature and the coating is subsequently contacted with a body at the body temperature during handling, the body experiences an attenuated thermal sensation.
