Measuring device for the mechanoelectric measurement and monitoring of physiological activities in an electrically evoked stapedius muscle tissue (eKEHRT sensor)

摘要

The invention relates to a measuring device for measuring and monitoring physiological activities in an electrically evoked Stapediusmuskelgewebe (eKEHRT sensor), in particular for non-contact measurement of the physiological activity of electrically evoked tissue, which is located in the middle ear of humans, consisting of a biocompatible sensor element (1). wherein the biocompatible sensor element (1) is arranged on or on a movable structure in the cavity of the middle ear with a corresponding fastener (4) and connected via a discharge electrode (5) with the cochlear implant, not shown, and in the Cochlear implant for attaching the external speech processor used round magnet (6) is used to generate a magnetic field. An additional, the sensitivity of the sensor element (1) increasing and an adjustment of the sensor element (1) facilitating mini coil (7) is integrated on or in the Ableitelektrode (5) or mounted in a bone window in the middle ear cavity.
