Изобретение относитс к медицинской технике, а именно к электрокардиографии .The invention relates to medical technology, namely to electrocardiography.
Известно устройство дл регистрации электрокардиограмм, содержащее электроды, покрытые электропроводной пастой, кабель отведений, переключатель отведений, усилитель биопотенциалов и устройство визуализации 1 .A device for recording electrocardiograms is known, comprising electrodes coated with an electrically conductive paste, a cable of leads, a switch of leads, an amplifier of biopotentials, and a visualization device 1.
В этом устройстве дл уменыдени переходного сопротивлени под индифферентным электродом площадь электрда значительно увеличена по сравнению с активными электродами. Такой путь снижени уровн помех малоэффективен и в некоторых случа х принципиально неприемлем.In this device, to reduce the transient resistance under the indifferent electrode, the area of the electrode is significantly increased compared with the active electrodes. This way of reducing the noise level is ineffective and in some cases fundamentally unacceptable.
Например, при регистрации ЭКГ в грудных отведени х, при наблюдении за больными, в спортивной медицине , физиологии труда, увеличение площадей электрюдов практически невозможно из-за сложности их креплени и необходимости локализации точек съема сигнала.For example, when registering an ECG in the chest leads, when observing patients, in sports medicine, in the physiology of labor, an increase in the area of electrons is almost impossible due to the complexity of their attachment and the need to localize the pickup points.
.Целью изобретени вл етс снижение уровн сетевых помех в регистрируемом электрокардиосигнале.The purpose of the invention is to reduce the level of network interference in the recorded electrocardiogram.
Это достигаетс тем, что устройство содержит вспомогательный электрод и генератор посто нного тока, . один полюс котсч ого подключен к вспомогательному электроду, а другой - к индифферентному электроду.This is achieved in that the device comprises an auxiliary electrode and a direct current generator,. One pole is connected to the auxiliary electrode, and the other to the neutral electrode.
На чертеже представлена структурна схема устройства дл регистрации электрокардиограмм.The drawing shows a block diagram of a device for recording electrocardiograms.
Оно содержит активные электрокардиографические электроды 1-4, индифферентный электрокардиограФический электрод 5 и вспомогательный электрод 6, наложенные на объект 7 обследовани через сагой 8 электропроводной пасты, переключатель 9 отведений, соединенный с электродамиIt contains active electrocardiographic electrodes 1-4, an indifferent electrocardiogram electrode 5 and an auxiliary electrode 6, superimposed on the object 7 of the examination, through sag 8, of conductive paste, a switch 9 of leads connected to the electrodes
кабелем 10 отведений, усилитель 11 биопотенциалов, вход которого подключен к выходу переключател 9 отведений, а выход св зан со входом устройства 12 визуализации, генератор 13 посто нного тока,.один полюс которого св зан с индифферентным электродом 5, а другой - со вспомогательным электродом 6. Устройство работает следующим cable 10 leads, the amplifier 11 biopotentials, the input of which is connected to the output of the switch 9 leads, and the output is connected with the input of the device 12 visualization, generator 13 DC, one pole of which is connected to the indifferent electrode 5, and the other to the auxiliary electrode 6. The device works as follows.
образом.in a way.
