Abstract
The invention relates to a device for hyperthermic treatment of itching, for example following insect bites, wherein during the treatment a treatment surface is regulated at a temperature of preferably between 42° C. and 56° C. for a period of 2 sec to 12 sec and a hardware-implemented temperature monitor limits the maximum temperature of the treatment surface and a safety fuse shuts off the device in the case of a short-circuit or uncontrolled continuous heating.
Claims14
A device for hyperthermic treatment of itching comprising:
- at least one treatment surface;
- a control device for regulating a temperature of the at least one treatment surface, wherein the control device is configured to regulate the temperature of the at least one treatment surface by heating at least one heating element in a heating phase to a treatment temperature of between 42° C. and 56° C. and in a treatment phase the control device is configured to maintain the treatment temperature for a period of 2 seconds to 12 seconds;
- a hardware-implemented temperature controller configured to:
- a) reversibly limit, independently of temperature regulation operation of the control device, a maximum temperature of the at least one treatment surface to a value of between 54° C. and 58° C., b) interrupt a power supply to the at least one heating element during a period in which the temperature of the at least one treatment surface exceeds the maximum temperature, and c) discontinue the interruption as soon as the temperature of the at least one treatment surface falls again below the maximum temperature;
- and
- a safety fuse configured to shut off the device in case of a short-circuit or uncontrolled continuous heating.
