Intelligent auscultation device

Abstract

The invention discloses an intelligent auscultation device, and relates to the technical field of medical electronics. The intelligent auscultation device comprises a sound cavity, an earphone, an audio processing module, an electrocardiogram module, a microcontroller and a signal processing module, The sound cavity is connected with the signal processing module; the signal processing module is connected with the audio processing module; the electrocardiogram module is connected with the microcontroller; the microcontroller is connected with the audio processing module and a remote network medical system; and the audio processing module is connected with the earphone. While sounds of the heart, the lung, the ribs or the abdomen are collected through the sound cavity, ECG signals can be collected through the ECG module. The intelligent auscultation device can detect heart sounds and lung sounds at the same time and has the ECG signal detection function.

Description

technical field [0001] The invention relates to the technical field of medical electronics, in particular to an intelligent auscultation device. Background technique [0002] In the detection of heart sounds and lung sounds, the traditional stethoscope detection method has great limitations. The common auscultation device on the market is an ear-hook auscultation device with a sound guide tube. It is the most commonly used diagnostic tool for doctors. Composition, the main function is to collect and amplify the sound from the heart, lungs, arteries and other organs, so as to diagnose cardiopulmonary diseases. [0003] The ear-hook auscultation device with a sound guide tube is only for use by doctors. The tester must go to the hospital or clinic for heart sound and lung sound detection, which increases the risk of cross-infection and brings great inconvenience to patients in areas where medical resources are scarce; For doctors examining patients, ear-hook auscultation dev...

Problems solved by technology

[0003] The ear-hook auscultation device with a sound guide tube is only for use by doctors. The tester must go to the hospital or clinic for heart sound and lung sound detection, which increases the risk of cross-infection and brings great inconvenience to patients in areas where medical resources are scarce; For doctors examining patients, ear-hook auscultation devices with sound guide tubes are likely to be mixed with other environmental interference noises, making it difficult for doctors to capture weak heart sounds and breath sounds, resulting in easy neglect of part of the information. , heart sounds and breath sounds are mixed during auscultation, interfere with each other, and become noises, which is not conducive to the doctor's judgment; and in order to reduce the interference of external noise, the clamping force of the earhook on the ear is relatively large, which will bring the doctor's ear It is very uncomfortable and cannot be worn for a long time; the diagnosis of the patient's heart sound and lung sound is only based on one's own experience, the diagnosis is lagging, the cost is high, and it is not accurate. The size of the heart sound and lung sound is transmitted through the sound guide tube When it reaches the doctor's ear, the sound is not very loud, which may cause the doctor to misjudge and misdiagnose, which will bring some troubles to himself and the patient; the detected data cannot be stored in real time, and the contrast is poor, which is of great help to the later stage. The follow-up diagnosis brings great inconvenience

The traditional auscultation device can only solve the problem of heart and lung sound detection, and does not have the data of ECG electrocardiogram detection, which reduces the comprehensiveness of the initial detection data of the tester, and lacks necessary information when dealing with complex symptoms such as palpitations and chest pain. Analyzing data, but the traditional 12-lead electrocardiogram machine is relatively large and expensive. It needs to establish leads for measurement, requires professional doctors to operate, and takes a long time

[0004] In summary, there are the following problems in the ear-hook auscultation devices with sound guide tubes on the market: 1) patients cannot perform real-time detection of their own health status; 2) external and internal noise interference is not conducive to accurate diagnosis by doctors; 3) when testing The discomfort of wearing an auscultation device for doctors; 4) The diagnosis is based on experience, and accurate diagnosis cannot be made; 5) The sound of heart and lung sounds is small; 6) There is a risk of cross-infection; 7) There are problems such as lack of real-time storage and recall of data; 8 ) without ECG detection function
