Device for the defined generation and measurement of power independently of position and path in a medical examination apparatus

摘要

For the purpose of power transmission a two-armed lever (20) is pivotably arranged in a housing (10). The upper lever arm (20a) carries on its end a contact body (25) which can be placed on to the body part to be examined. Furthermore, the housing (10) comprises a power generation device which includes a permanently magnetic system and a rectangular coil (30) located on the free end of the lower lever arm (20b) of the lever (20). On rotation of the lever (20) the rectangular coil (30) is movable in the homogeneous field of the permanently magnetic system. However, the mobility of the lever (20) about its axis of rotation (21) can be limited in the homogeneous part of the permanently magnetic system. The rectangular coil (30) is connected with a driving and measuring electronics by means of flat gold bands (26). This permits defined generation and measurement of power independently of the position and path in a medical examination apparatus with electrical further processing of the measured results obtained.
