摘要
针对当前数字听诊器在长时间穿戴监测方面的不足,研制了一种具有可延展电路结构、可紧密贴合的柔性肺音无线听诊贴.对听诊贴的前端进音腔室、体表贴合性、可延展电路结构的力学—电学性能以及信号降噪方面展开研究.结果表明:该柔性听诊贴可贴合体表,可延展电路在体表动态环境中力学—电学性能稳定,最后对采样的肺音信号经过小波阈值降噪后信噪比显著提高,实现了持续动态监测的可穿戴数字化听诊,可为后续肺部的持续诊疗工作提供一定的研究价值.
Abstract
Aiming at the shortcomings of the current digital stethoscope in long-term wear monitoring,a flexible wireless auscultation patch which has an extendable circuit structure for lung sound that can be tightly fitted is developed.Research on front-end inlet chamber of the auscultation sticker,the body surface adhesion,the mechanic-electrical properties of the extensible circuit structure,and the signal noise reduction are conducted.The results show that the flexible auscultation front end can closely fit the body surface,the mechanical-electrical stability of the extendable circuit structure is good,and the signal-to-noise ratio of the sampled lung sound signal is significantly improved after wavelet threshold noise reduction,the wearable digital auscultation with wireless long-term dynamic monitoring is realized,which can provide a certain research value for the follow-up continuous monitoring of the lungs and medical diagnosis.
