Abstract (en)
The aid has a housing (1), and an electrical heating device (3) arranged in the housing. Electrically conducting contacts (5) connect an electrical energy source arranged outside the housing to components inside the housing. The contacts charge a rechargeable battery (2) arranged in the housing, and supply electrical energy to the heating device. A closable opening is arranged in a housing wall, where the heating device is implemented as an ohmic resistance heater and a partial covering of the wall.
