摘要：
A useful model refers to medical technology, in particular to devices for electropuncture and can be used for auricular diagnosis of biologically active points (BAP) of a person. The multi-electrode scanner is made in a monoblock configuration and consists of a cylindrical body 1 connected through a conical cover 2 with a detachable curved tip 3 by means of threaded connections. Inside the case 1 is installed one printed circuit board 4. On the printed circuit board 4 are placed the main scanner units: the electronic switch 5 with microelectrodes 6, the current source 7 with the current value switch 8 and the shunting resistor 9, the zero-pointing unit 10 with the amplifier 11 and the gain switch 12, the control microcontroller 13, the isolating interface 14 to the power supply 15. In one end face of the housing 1 is installed a removable tip 3, in which a package of sixty-four microelectrodes 6 with a part of the printed circuit board 4 is enclosed. The microelectrodes 6 are isolated from each other and rigidly fixed at the tip 3. Their outputs to the working surface are distributed over a given grid of distances between them, and the opposite outputs are connected to the electronic commutator 5. At the other end of the housing 1, an opening is made for the shielded interface cable 16, which contains an additional insulated wire 17. One end of the shielded interface cable 16 and an additional isolator The wires 17 are fixed by soldering on the printed circuit board 4 and are housed in the housing 1 and the other end of the cable 16 is equipped with a standard interface connector 18 for connection to a personal computer. The auxiliary wire 17 is not connected to the connector 18, and is derived from it as a separate insulated conductor for connection of the passive electrode 19. The monoblock design of the multi-electrode scanner gives the device the functional completeness of the stand-alone device and improves the comfort of its operation, and placing all electron
