Problems solved by technology

[0003] However, in practice, because the stethoscope can only allow doctors or related personnel to determine the corresponding cause or focus by listening to the sound, misdiagnosis is very likely to occur, leading to unforeseen serious consequences

Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] One of the core concepts of the present invention is to obtain physiological parameters that comprehensively and accurately reflect the functions of the cardiovascular system by acquiring acoustic-electric signals, electrocardiogram signals and photoelectric pulse wave signals, and integrating the information carried by these three signals. .

[0036] Based on the mathematical and physical model determined by hemodynamic principles, multiple quantitative parameters about the cardiovascular and circulatory system of the tested organism can be obtained from the extracted pulse wave signal, thus objectively and effectively realizing the detection of the measured biological The detection of cardiac function, blood vessels, and ...

Abstract

The utility model discloses an electronic auscultation device that comprises an acoustoelectric signal transducer, an ECG signal acquiring device, a photoelectric pulse wave signal acquiring device, a signal processing unit and a parameter acquisition unit. The signal processing unit is used for processing the signals acquired by the acoustoelectric signal transducer, the ECG signal acquiring device and the photoelectric pulse signal acquiring device. And the parameter acquisition unit is used for acquiring preset physiological parameters from the signals output by the signal processing unit. The invention provides the electronic auscultation device that can monitor an ECG signal, a heart sound signal and a photoelectric pulse wave signal. The electronic auscultation device can not only monitor the sounds caused by organ activities, the ECG signal, and the pulse wave signal but also calculate a plurality of the physiological parameters of heart rate and blood pressure, thus improving the accuracy of disease diagnosis.

Description

technical field [0001] The invention relates to a device for disease diagnosis, in particular to an electronic stethoscope device. Background technique [0002] The stethoscope is an instrument for diagnosing organ activity by detecting sound. The electronic stethoscope collects the sound of the heart, lung and other organ activities by placing the earpiece on the corresponding part of the measured organism, and converts these sounds into electrical signals. After amplification, the sound will be emitted directly from the speaker, so that doctors or related personnel can determine the cause or focus of the disease according to the corresponding sound signal and make a correct diagnosis. Obviously, the main purpose of the current stethoscope is to collect heart sounds or lung sounds. For example, Chinese Patent No. 02124481.2 discloses a stethoscope earpiece that can simultaneously receive heart sounds and lung sounds, and can separate heart sounds and lung sounds according t...
