The medical appliance includes a first setting device disposed at an outer side on a housing of the appliance, and a second setting device disposed in the interior of the appliance. The second setting device is designed to actuate a setting element for adjustment of a controllable and/or regulatable device. The first setting device and the second setting device each comprise magnet elements, by which the first setting device cooperates with the second setting device in such a way that the one setting device actuates the other setting device for the transmission of adjustments, the cooperation of the setting devices being achieved by way of a magnetic coupling.
