Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] A heart monitor, such as figure 1 As shown, it includes: lead electrode 1; an ECG signal preprocessing module for differentially amplifying human ECG signals detected by lead electrode 1, common-mode suppression for external environment noise, and filtering high-frequency signals 2; Motion sensor module 3; Adjustable band-pass filter 4; Used to reduce the bandwidth of the adjustable band-pass filter 4 to filter out motion interference signals when the motion sensor module 3 detects a large amount of human body movement, and in the motion sensor module 3 detect the small amount of human body...

Abstract

The invention provides an ECG monitor. A connected electrode is connected with the input terminal of an electrocardiosignal pre-processing module; the output terminal of the electrocardiosignal pre-processing module is connected with the input terminal of an adjustable band-pass filter; the output terminal of the adjustable band-pass filter is connected with the input terminal of the electrocardiosignal processing module; the control terminal of the adjustable band-pass filter is connected with a microcontroller; the output terminal of the electrocardiosignal processing module is connected with the microcontroller; the output terminal of a movement sensor module is connected with the microcontroller; and the input terminal of a data processing module is connected with the microcontroller. The ECG monitor controls the passband bandwidth through detecting the motion state of a human body to eliminate interference caused by motion artifacts, and can be used not only when the human body is in a quietly lying state but also when the human body is in a motion state, thereby realizing all-day heart monitoring under the condition of not influencing the normal life of users.

Description

technical field [0001] The invention belongs to the field of monitoring medical equipment, in particular to an electrocardiographic monitor. Background technique [0002] Heart disease is one of the main diseases that have been threatening human life and health, and a large part of them are patients with hidden heart disease. Although the hospital examination has a certain probability of detecting heart disease, but due to the accidental and unpredictability of heart attack, the difficulty of examination will inevitably increase. [0003] With the continuous improvement of ECG monitoring technology, ECG monitors (EGC) are more and more recognized, and ECG monitors also bring good news to more people. However, the filter bandwidth of a general ECG monitor is fixed, and cannot filter out the interference of motion artifacts. Therefore, general ECG monitors can only be detected when the human body is lying still, and cannot be detected during human motion. Therefore, many us...
