Device for the treatment of Herpes diseases

A device for treating a herpes disease on skin of a lip or other skin, comprising:

• at least one treatment surface with a maximum size of 60 mm2;
• and
• a control device for regulating the temperature of the treatment surface, the control device being configured to regulate the treatment surface on an outer side facing the skin by heating at least one heating element in a heating phase to a contact temperature of 43° C.-47° C. during a contact of the treatment surface with the skin, and maintain the contact temperature in a treatment phase for a time period between 1 and 10 seconds wherein the contact temperature refers to the temperature which the treatment surface exhibits on an outer side facing the skin, while the outer side is in contact with the skin area, wherein the treatment surface is formed by a gold or ceramic layer and the contact temperature is determined by:
• a temperature sensor integrated within or present on the inner side of the treatment surface;
• wherein the temperature sensor measures a temperature and the control device is configured to determine the contact temperature at the outside of the treatment surface based upon the temperature measured by the temperature sensor by further taking into account a heat flow within the treatment surface, wherein the difference between the temperature measured by the temperature sensor and the contact temperature is provided to the control device based upon theoretical predictions about the heat flow within the treatment surface, when in contact with the skin, or based upon calibration measurements as reference data:
• wherein the temperature measured by the temperature sensor is higher than the contact temperature, and
• wherein the control device is configured to set a target temperature on the inner side of the treatment surface in a feedback regulation of the heating to a higher temperature than the desired contact temperature on the outer side of the treatment surface during the contact based upon said difference between the temperature measured by the temperature sensor and the contact temperature.
