Abstract

Изобретение относитс  к медицинской технике и может быть использовано в приборах дл  регистрации и/или автоматической обработки биоэлектрических сигналов, в частности э ектрокардиосигналов, Целью изобретени   вл етс  расширение области применени  устройства и повышение достоверности его выходных сигналов. Сущность изобретени  заключаетс  в том, что в устройство , содержащее электроды 1, мультиплексор 3, блок 4 управлени  мультиплексором, дифференциальный усилитель 5, модул тор 6, блок 7 гальванической разв зки, усилитель 8 модулированного сигнала, генератор 13 тактовых импульсов, дзмультиплексор 9, блок 14 управлени  демультиплексором, блок 12 анализа, блок 16 индикации и блоки10 демодул ции , введены блок 2 весовых цепей, блоки 11 полосовых фильтров и блок 15 логической обработки. Это позвол ет использовать устройство дл  съема и усилени  сигналов как бипол рных, так и унипол рных электрокардиографических отведений, обеспечивает повышение чувствительности контрол  к нарушени м контакта между кожей и отвод щими биопотенциалы электродами , а также локализацию и индикацию места нарушени  контакта. 5 ил. у ЈThe invention relates to medical equipment and can be used in devices for recording and / or automatic processing of bioelectric signals, in particular electrocardiograms. The aim of the invention is to expand the scope of the device and increase the reliability of its output signals. The invention consists in that in a device containing electrodes 1, a multiplexer 3, a multiplexer control unit 4, a differential amplifier 5, a modulator 6, a galvanic isolation unit 7, a modulated signal amplifier 8, a clock pulse generator 13, a multiplexer 9, a block 14, a demultiplexer control unit, an analysis unit 12, an indication unit 16, and demodulation units 10, a weight circuit unit 2, bandpass filter units 11, and a logic processing unit 15 are introduced. This makes it possible to use the device for capturing and amplifying signals of both bipolar and unipolar electrocardiographic leads, provides an increase in the sensitivity of controls to disturbed contact between the skin and the biopotential potential electrodes, as well as localization and indication of the place of contact disturbance. 5 ill.
