Problems solved by technology

[0003] Most of the current diagnostic equipment has a single function. Heart sounds can only be auscultated, and electrocardiograms can only monitor ECG.
For the situation where comprehensive diagnosis of heart sound and ECG is required, the equipment needs to be replaced, which will inevitably result in low inspection efficiency
Chinese patent 201020217790.6 involves a device that integrates heart sound and ECG, but the heart sound monitoring probe of this device uses a piezoelectric film, and the accuracy is not high
Our recent research found that due to the large size of the microphone, the noise generated by friction, and the disadvantages of being unsuitable for wearable devices, the accuracy of stethoscopes based on microphones often cannot meet our requirements

Embodiment Construction

[0022] like figure 1 It is a schematic diagram of the structure of the heart sound ECG two-in-one probe. The electrodes 102 are located at the bottom of the two-in-one heart sound and ECG probe, and can directly contact the human body during use. A layer of insulating material with the same size as the electrode is used above the electrodes, and the sound sensor module is attached to the insulating material. The insulating material and the electrodes are closely bonded, which can transmit the vibration to the sound sensor well. The electrode, insulating material and sound sensor module are wrapped with a hard, insulating and sound-insulating cylindrical shell 104 to form a probe. 105 is a sound sensor wire, and 106 is an electrocardiographic electrode wire, which conducts the electrical signals of the sensor and electrodes to the signal processing system. The sound sensor adopts the principle of piezoelectric effect and is made into an asymmetric cantilever beam structure ...

Abstract

The invention discloses a comprehensive heart detection device based on heart sound and electrocardiogram, which includes a signal processing system connected with several heart sound and electrocardiogram two-in-one probes, the signal processing system is connected with a terminal display device, and the heart sound and electrocardiogram two-in-one probe The integrated probe includes a sound sensor and electrodes for collecting heart sounds and electrocardiographic signals; the signal processing system is used for processing the collected heart sounds and electrocardiographic signals, and transmits the processed signals to the terminal display device; the terminal display The device is used to display phonocardiogram and electrocardiogram. The electrocardiographic electrode of the present invention can directly contact with the skin, improve the sensitivity and precision of the probe, detect heart sound and electrocardiogram at the same time, and contribute to disease diagnosis.

Description

technical field [0001] The invention relates to a heart comprehensive detection device based on heart sound and electrocardiogram. Background technique [0002] Heart sound signal analysis is a basic method to evaluate the functional state of the heart. The heart sound signal contains a large amount of physiological and pathological information about the human heart and blood vessels, and also contains part of the information about the human cardiopulmonary circulatory system and the whole body circulatory system. The electrocardiogram uses the bioelectrical changes produced by the heart in each cardiac cycle, and obtains the graph of the potential changes through the electrocardiograph. The electrocardiogram is an objective indicator of the occurrence, propagation and recovery process of cardiac excitement. [0003] Most of the current diagnostic equipment has a single function, the heart sound can only be auscultated, and the electrocardiogram can only monitor the electr...
