Embodiment 1
[0014] Example 1 ： Such as figure 1 The shown ECG monitoring equipment includes ECG collecting electrodes, ECG amplifiers, filter circuits, preamplifier circuits, AD converters, single-chip microcomputers and displays connected in series in sequence; the ECG collecting electrodes are connected with the ECG amplifiers to form a Electric signal acquisition circuit, the collected ECG signal is filtered out by the filter circuit and then amplified by the pre-amplification circuit. The amplified ECG signal is converted into a digital signal by the AD converter and sent to the single-chip microcomputer. The single-chip microcomputer processes the signal and passes it through the display. to display. The AD converter adopts the ADC0808 chip, and the single-chip microcomputer adopts the AT89C51 chip.
[0015] ECG acquisition electrodes include reference electrodes, positive input electrodes, and reverse input electrodes, which are connected to the ECG amplifier through shielded w...

The invention discloses electrocardiogram monitoring equipment. The electrocardiogram monitoring equipment comprises an electrocardiogram acquisition electrode, an electrocardiogram amplifier, a filter circuit, a pre-amplifier circuit, an AD converter, a single chip microcomputer and a displayer which are connected in series in sequence; after the electrocardiogram acquisition electrode is connected with the electrocardiogram amplifier, an electrocardiosignal acquisition circuit is formed, acquired electrocardiosignal is amplified through the pre-amplifier circuit after filtering out an interference signal through the filter circuit, the amplified electrocardiosignal is converted into a digital signal through the AD converter to the single chip microcomputer, and the single chip microcomputer processes the signal and displays the signal through the displayer. According to the electrocardiogram monitoring equipment, the acquired weak electrocardiosignal is amplified 8 times through the pre-amplifier circuit, filters the interference signal out through the filter circuit and is amplified through the pre-amplifier circuit, converted through the AD converter and processed through the single chip microcomputer, and the final result is accurate; the whole circuit is simple in result, low in component cost and suitable for application and popularization.
Description
technical field [0001] The invention relates to medical equipment, in particular to an electrocardiogram monitoring equipment. Background technique [0002] At present, with the rapid development of electronic medical technology and the mutual promotion of clinical medicine, various ECG monitoring products have appeared. Major domestic medical device factories and scientific research institutes have invested a lot of resources in the development of ECG monitoring systems. And all have developed ECG monitoring products with their own characteristics. But the electrocardiogram signal is relatively weak, and the existing electrocardiogram monitoring products are mostly achieved by improving the hardware to improve the efficiency of monitoring, and the price of such products is too high to be popularized. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies of the prior art, the present invention provides an electrocardiogram monitoring devi...
