    摘要: The invention relates to a device and a method for aiding the positioning of an external transmitting part relative to an implantable receiving part of a charging system for charging a rechargeable power source of an implantable medical device such as an implantable hearing aid. The external transmitting and the implantable receiving part each has a resonant circuit with a transmitting coil and a receiving coil respectively. These coils can be inductively coupled to one another by corresponding manual positioning of the external transmitting part for transcutaneous power transmission. The external transmitting part is provided with an oscillator which is connected to the transmitting resonant circuit and the oscillator has a resonant frequency which shifts as a function of the coupling between the transmitting coil and the receiving coil. The external transmitting part is also provided with a measurement arrangement for determining the frequency detuning of the oscillator and an evaluation arrangement for outputting a positioning signal as a function of the determined frequency detuning of the oscillator.
