ELECTROCARDIOGRAPH AND BIOELECTRODE PAD |
摘要 |
<p>[Problem] To provide an electrocardiograph capable of stably measuring an electrocardiac signal without being disturbed by body motion noise. [Solution] An electrocardiograph measures an electrocardiac signal by processing electric signals detected by using a plurality of bioelectrode pads attached to the skin of a living body and is characterized as follows. The bioelectrode pads each comprises: a plurality of sheets of electrodes disposed by being stacked on each other; conductive gel sheets disposed alternately with the sheets of electrodes and interposed between the electrodes; and a dynamic pressure stabilizing plate disposed by being stacked in a stacked direction of the sheets of electrodes, on the side opposite to the side of the skin, outside the sheets of electrodes. The electrocardiograph comprises: a first differential circuit for obtaining an electrocardiac source signal by taking the difference between signals each obtained from any one of the electrodes of each of two bioelectrode pads among the plurality of bioelectrode pads; a second differential circuit for obtaining a body motion noise signal by taking the difference between signals obtained from any two of the electrodes of each of said two bioelectrode pads; and a body motion noise removing circuit for removing the low frequency components of the body motion noise signal of each of said two bioelectrode pads from the electrocardiac source signal.</p> |
