    A number of measuring electrodes for emplacement on the head of a patient, signal amplifiers whose input channels are connectable, via a selector, to the measuring electrodes according to a pattern selection program, and recorders controlled by the output signals of the signal amplifiers. The selector manifests, in a head-image area, one electrode switch for each measuring electrode, by means of which electrode switch the measuring electrode is connectable to an input channel, and which electrode switch is arranged in a position relative to the head-image area corresponding to the application location of the measuring electrode.

    (54) ELECTROE NCEPHALOGRAPH
    one
     The invention relates to medical technology.
    The electroencephalograph is known, which contains discharge electrodes, j input amplifiers, switching units, a selection circuit and a multichannel recording instrument IJ.
    However, when controlling a known encephalograph, the operator has Q difficulties when selecting and connecting for recording points of bioelectrical signals, since the device does not have a clear idea of the placement of electrodes on a person. This deficiency leads to research errors and delay in the research process.
    The aim of the invention is a zero-d, 0-point test.
    The goal is achieved by the fact that in an electroencephalograph containing successively connected discharge electrodes, input amplifiers, switching units, a selection circuit and a multichannel recording device, the selection circuit is made in the form of an image of a human head with switches placed on it,
    They are equipped with appropriate discharge electrodes, which, when examined, are located at the same place of the human head.
    In this case, the circuit of each switch on the image of the human head contains an indicator lamp.
    In addition, the selection scheme of contents-. A switch of the input amplifiers is used to connect the switches of the selection circuit with the corresponding diverting electrodes.
    Fig. 1 shows a scheme for connecting an electroencephalograph to a patient; Fig. 2 illustrates the selection circuit; Fig. 3 shows the connection circuit of the switching units with the selection circuit and the discharge electrodes.
    The electroencephalograph contains discharge electrodes 1, developed on the human head, input amplifiers 2, switching units 3, selection circuit 4 and multichannel recording device 5 with recorders 6. Selection circuit 4 (figure 2) is made in the form of an image 7 of a human head with placement On it, switches 8, which are connected to the corresponding discharge electrodes 1, which are intended to be used during the examination, are located at the same place of the human head. The circuit of each switch 8 on the head of a man’s head 7 contains an indicator lamp 9. The selector circuit 4 contains a switch of 10 channels of input amplifiers with switches 11 equipped with indicator lights 12, which are designed to connect the selector circuit switches 8 with the corresponding tap electrodes 1. The electroencephalograph in the following way. By activating the switches 8, the corresponding at the location of the discharge electrode 1 is connected to the input amplification channel. To indicate the electrode connected to register the bioelectrical signal, use lump 9, combined with switch 8. To select the recording channel, use switch 10, using switch 11 of which activates the corresponding switching unit 3 with the input amplifier 2. As a result, the previously selected output electrode 1 is connected to amplifier 2. Thus, the design of the electroencephalograph provides the consistency of the process of connecting the discharge electrodes and connecting the latter to the input amplifiers. the efficiency and accuracy of the research is ensured. The formula is 1. An electroencephalograph containing serially connected discharge electrodes, input amplifiers, switching units, a selection scheme and a multichannel recording device, characterized in that, for the purpose of error-free research, the selection scheme is made in the form of an image of a human head placed on it switches connected to the respective discharge electrodes, which are intended for examination at the same place of the human head. 2. An electroencephalograph according to claim 1, characterized in that the circuit of each switch in the image of the human head contains an indicator lamp. 3. The electroencephalograph according to claim 1, characterized in that the selection circuit comprises a channel switch for input amplifiers for connecting the switches of the selection circuit with the corresponding diverting electrodes.
