Device for the determination of characteristics, differences and changes in the human or animal body

摘要

The subject of the application is a device for the determination of characteristics, differences and changes in the human or animal body, alive or dead, with an alternating current source which is connected via a pole directly or indirectly to the body being examined, and with an electrical measurement device which is arranged between the other pole of the alternating current source and a scanning element with an electrode guided over the surface of the body. A spacing piece or spacing pieces is/are provided on the electrode, and the electrode is arranged at a distance from the surface of the device guided over the body. The electrode and/or the spacing piece and/or the optionally available housing is provided with one or more earthed layers or covers (protections) of conductive material or paint material, of which, if a housing is present, at least one is arranged entirely or partially on the outside of the housing or inside its wall for the protection of the electrode and/or its line. In this device, the protection (84, 33, 93, 113, 123, 136, 154, 158, 164, 173, 180, 185, 189, 193, 196, 202, 209, 217, 227, 233, 264, 272, 282, 292), which is optionally provided entirely or partially with an insulation, has a front edge (132, 156, 181, 193, 275, 285, 295) which is fitted for contact with the measuring body and diversion of the high-frequency field. This device has the particular advantage that it delivers substantially stable measurement values while at the same time being easy to handle.
