<p>An instrument for localized thermotherapy in which heated air is so projected onto a limited surface area on the body of a patient overlying a problem region as to bring about the rapid transfer of heat energy toward this region to raise the temperature thereof without, however, causing undue discomfort or injury to the patient. In the apparatus described, air heated to a temperature well above normal body temperature is projected as a high velocity wind toward the limited surface area in a pulsatory thermal-wave pattern, thereby subjecting the area to high-temperature, high-velocity air pulses separated by lower air temperature, relatively static intervals. As a consequence, rapid heat transfer takes place through the body tissue during these intervals, this inward transfer acting to reduce the temperature at the surface to a degree preventing an undue rise thereof. The surface area is protectively coated with a suitable jelly to prevent wind burn and to minimise the outward transfer of heat energy from the surface area to the atmosphere.</p> |
