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] Such as 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 structu...

Abstract

The invention discloses a heart comprehensive detection equipment based on heart sounds and electrocardiograms. The equipment comprises a signal processing system connected with a plurality of heart sound-electrocardiogram two-in-one probes, wherein the signal processing system is connected with a terminal display device, and each heart sound-electrocardiogram two-in-one probe comprises a sound sensor and an electrode and is used for collecting a heart sound signal and an electrocardiosignal; the signal processing system is used for processing the collected heart sound signals and electrocardiosignals and transmitting the processed signals to the terminal display device; the terminal display device is used for displaying electrocardiograms and heart sound diagrams. According to the heart comprehensive detection equipment, the electrodes can be directly contacted with skin, so that the sensitivity and accuracy of the probes are improved; the heart sounds and the electrocardiograms are detected at the same time, so as to 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...
