技术领域technical field
本发明涉及听诊领域，具体是一种多功能发声无线听诊装置及听诊提醒分析方法。The invention relates to the field of auscultation, in particular to a multifunctional sounding wireless auscultation device and an auscultation reminder analysis method.
背景技术Background technique
听诊是用耳或听诊器来探听人体内自行发出的声音，多用于听心音、呼吸音等。通过听诊，医护人员可根据声音的特性与变化(如声音的频率高低、强弱、间隔时间、杂音等)来诊断相关脏器有无病变。现有的听诊装置在进行听诊时需要医护人员通过经验来将听诊器摆放到一个合适的听诊位置，这种经验的主观性太强，容易导致听诊声音不够清楚，从而导致听诊的结果不够精确；除此之外，医护人员来听诊具有一定的主观性，如果医护人员听诊经验不够，听诊结果可能会出现错误。Auscultation is the use of ears or a stethoscope to detect the sounds produced by the human body. It is mostly used to listen to heart sounds, breath sounds, etc. Through auscultation, medical staff can diagnose the presence or absence of lesions in related organs according to the characteristics and changes of the sound (such as the frequency, strength, interval, noise, etc.) of the sound. Existing auscultation devices require medical staff to place the stethoscope to a suitable auscultation position through experience. This experience is too subjective, which easily leads to unclear auscultation sounds, resulting in inaccurate auscultation results; In addition, the auscultation by the medical staff is subjective to a certain extent. If the medical staff has insufficient auscultation experience, the auscultation results may be wrong.
