Abstract (en)

[origin: WO2007082648A1] Different designs of hand-held devices for therapeutic skin treatment by application of heat are known. Inexpensive hand-held devices use heat radiation. In practice, however, there is no inexpensive hand-held device available that can be placed on the skin to be treated and that operates according to the principle of heat conduction and allows the skin to be treated within a defined temperature range without the use of a temperature sensor and control elements. To provide the user with an easy-to-use hand-held device that is inexpensive to produce and is based on the principle of heat conduction, the hand-held device according to the invention for thermal treatment of an area affected by an insect sting or bite comprises: a heat-conducting body (K) which is mounted in the housing (G) of the hand-held device and can be brought into contact with the skin (H) of the user, a temperature-dependent resistor which is arranged on or in the heat-conducting body (K) and is thermally coupled to the latter and has a positive characteristic curve (PTC), a keypad element (T) that can be manually actuated by the user, and a voltage source (B) arranged in the housing (G) of the hand-held device, such that, depending on the duration of actuation of the keypad element (T) and depending on the heat transfer resistances (RTHI, RTH2, RTH3) between temperature-dependent resistor (PTC), heat-conducting body (K) and skin (H), the heat-conducting body (K) on the skin contact surface (HK) can be heated by the heat of the temperature-dependent resistor (PTC) to a temperature in the temperature range between 50°C and 65°C. The invention applies to the field of medical equipment.
