FIELD: physics; measurement. ^ SUBSTANCE: present invention relates to stand-alone gastrointestinal tract electrostimulators and means of indicating their operation in a given mode. The invention seeks to create a portable, noise-proof, easy to use indicator for functioning of the said device, with advanced functional capabilities. The proposed indicator has two input electrodes, meant for tapping voltage from human skin, cascade-connected voltage amplifier and a bipolar comparator-limiter, cascade-connected monostable multivibrator of sound frequencies, current amplifier, acoustic radiator, independent power supply, auxiliary electrodes for connection to the stand-alone gastrointestinal tract electrostimulator, rectifier of the signal from the stand-alone gastrointestinal tract electrostimulator, a two-input light indicator, double mechanical switches and a dielectric casing, made in form of a rectangular parallelepiped, a unipolar mechanical switch, a converter for converting unipolar voltage of the independent power supply into bipolar voltage relative the global bus, a simulator of the signal from the stand-alone gastrointestinal tract electrostimulator and two paired normally opened electronic switches, electrically connected and mechanically linked accordingly. ^ EFFECT: design of a portable, noise-proof, easy to use indicator for functioning of the said device, with advanced functional capabilities. ^ 2 dwg |
