Heating device for heating a skin surface on partial areas of the human body
First Claim
1. Heating device for heating or maintaining the temperature of a skin surface with a deep effect on a body zone of a human body, comprising:
- a heat transfer element;
an energy supply device connected via an energy transfer device to the heat transfer element; and
a control and switching device for controlling a power end stage so as to control energy supply to the heating element from the energy supply device, the control and switching device having an oscillating switching circuit for generating constant pulse signals, and an adjustable pulse modulation switching circuit for altering the pulse signals for controlling the power end stage;
wherein the heat transfer element comprises a multilayered construction having a film-like base layer formed of a resilient and heat-insulating breathable material, and a heating element attached via an adhesive to an inner side of the base layer, the heating element including a fiber-reinforced resin film attached to the base layer, a heating conductor layer attached to the fiber-reinforced resin film, and a resilient microporous cover layer adhered to and covering the heating conductor layer.

Abstract
The invention relates to a heating device (1), particularly for heating and/or maintaining the temperature of a skin surface with a depth effect on partial areas of a human body. The latter has at least one heat transfer element (2) comprising a heating element (3) and an energy supply device connected by an energy transfer device to the heat transfer element (2), and preferably a control and/or switching device (9). In order to supply the heating element (3) with energy, an oscillating switch circuit is located in the control and/or switching device (9) in order to generate constant pulse signals. Following this is an adjustable pulse modulation switching circuit for altering the pulse signals for controlling a power end stage.
