Patent ID: 8100891

Claim:
A medical appliance with an adjustment apparatus, comprising: a first setting device disposed at an outer side of a housing the appliance; and a second setting device disposed in an interior of the appliance, the second setting device being designed to actuate a setting element for adjustment of a controllable and/or regulatable device, wherein the first setting device and the second setting device each comprises magnet elements, by which the first setting device cooperates with the second setting device in such a way that one of the first and second setting devices actuates the other of the first and second setting devices in order to mediate an adjustment of the controllable and/or regulatable device, such that the cooperation of the first and second setting devices is achieved by way of a magnetic coupling, wherein the first setting device is constructed such that the first setting device is placed on a receiving element, wherein the receiving element is formed so as to be integral with and protruding from the housing, such that the first setting device is then rotatably disposed on and surrounding the receiving element, wherein in order to transmit an adjustment in the form of a moment of torque by way of the setting devices, the magnet elements of the first setting device and the second setting device are disposed with respect to one another in such a way that they produce a magnetic field that is not rotationally symmetric with reference to an axis of rotation of the setting devices, so that during rotation of one of the setting devices the magnetic field between the magnet elements undergoes an alteration which produces mutual entrainment of the setting devices.
