MULTICHANNEL RECORDER OF BIOPOTENTIALS STANDARD VALUES Russian patent published in 2017 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: multichannel recorder of biopotentials standard values contains N input channels, each of which includes serially connected input electrode, amplifier, low pass filter and the first input key, with the outputs of the first input keys connected to a dial-up filter input, the output of which is connected to a microcontroller via the serially connected mean square value detector and ADC; microcontroller digital output is connected to a device for information recording and display. Between the dial-up filter outputs connected to inverting inputs of the corresponding operational amplifiers of the dial-up filter and dial-up filter outputs connected to the outputs of the corresponding operational amplifiers of the dial-up filter, electrical circuits of the dial-up filter are formed, each of which consisting of N parallel branches, each of which being formed by serially connected analog key and capacitor, and between the corresponding outputs of the mean square value detector, an electrical circuit of the mean square value detector is formed consisting of N parallel branches, each of which being formed by serially connected analog key and capacitor. The first input key control input of each input channel from the first to the N-th is connected to the respective control inputs of analog keys of each parallel branch, and is connected to the corresponding first to N-th microcontroller control output.

EFFECT: use of the invention allows to increase the accuracyand identity of signal registration.
