Abstract
A hand-held device for the local heat treatment of a patient's skin comprises a casing composed of a lower treatment part having a bottom wall with an external treatment face, and an upper handle part, and an electric heating unit in the treatment part comprising a power transistor with a cooling vane and a heat sensor, the cooling vane and the heat sensor being in heat transfer contact with the interior surface of the bottom wall, and an electric circuit unit inside the treatment part for controlling electric current flow through the power transistor depending on temperature variations detected in the bottom wall by the heat sensor. The circuit is fed low voltage direct current from a source therefor.
