Embodiment 1

[0028] refer to figure 1 A shared stethoscope diagnostic system for patients with pulmonary nodules, the system includes the following components: a sound sensor, used to collect sound data of the human body; a mode switch, used to switch to the measurement mode corresponding to the frequency of the sound data, wherein, The stethoscope system has at least two measurement modes. In different measurement modes, the filtering frequency range of the stethoscope system is different; the preamplification circuit is used to amplify the collected sound data. In the embodiment of the present invention, the sound sensor is used to collect the sound data of the human body; the mode switch is used to switch to the measurement mode corresponding to the frequency of the sound data, wherein the stethoscope system has at least two measurement modes. In the measurement mode, the filter frequency range of the stethoscope system is different; the preamplifier circuit is used to amplify the colle...

Embodiment 2

[0038] refer to figure 1 A shared stethoscope diagnosis system for patients with pulmonary nodules, the stethoscope system further includes: an analog-to-digital conversion circuit, which is used to perform analog-to-digital conversion on amplified data to obtain digital signals.

[0039] Further, the stethoscope system further includes: a noise reduction circuit, configured to denoise the digital signal to obtain denoised data.

[0040] Further, the stethoscope system further includes: a post-amplification circuit, configured to amplify the denoising data to obtain post-amplification data.

[0041] Further, the sound data of the human body collected by the sound sensor includes: heart sounds, lung sounds, heart-lung sounds, extended heart-lung sounds, and bowel sounds.

[0042] Further, the sound sensor is located in the stethoscope head of the stethoscope system, and the high-sensitivity sound sensor can be integrated with the medical stethoscope head.

[0043] Further, th...

Abstract

The invention relates to the technical field of stethoscopes, in particular to a shared stethoscope diagnosis system for pulmonary nodule patients. The shared stethoscope diagnosis system is used for solving the problem in the prior art that the application range is limited due to the fact that a stethoscope can only detect sound parameters of one human organ. The shared stethoscope diagnosis system for the pulmonary nodule patients comprises a sound sensor used for collecting sound data of a human body; a mode conversion switch which is used for switching different working modes such as heart sound, lung sound and borborygmus, wherein a stethoscope system has at least two working modes, and in different working modes, filtering frequency ranges of the stethoscope system are different; and a prepositioned amplification circuit for amplifying collected sound data; and analog input signals are converted into digital signals through analog-to-digital conversion. The problem that the application range is limited due to the fact that the stethoscope can only detect the sound parameters of one human organ is solved, and the effect of detecting the sound parameters of multiple human organs through the stethoscope is achieved.

Description

technical field [0001] The invention relates to the technical field of stethoscopes, in particular to a shared stethoscope diagnosis system for patients with pulmonary nodules. Background technique [0002] Traditional stethoscopes are difficult to capture the weak but very important sound signals from the internal organs and tissues of the human body, and cannot objectively preserve the transient characteristic sound. It requires high subjective identification ability of the user on site, which is not conducive to communicating with patients, patients' families, and others. Medical personnel exchange. [0003] Willem Einthoven developed a phonocardiograph, and Forgacs proposed a method of visually presenting human breath sounds using a breath sound map. With the help of signal processing technology, the intensity and frequency of heart sounds and breath sounds change with time. However, the standardization progress of phonocardiogram and breath phonogram is relatively slo...
