隔离式无线电子听诊器的研制及其应用研究

Development and practical application of an isolated wireless electronic stethoscope

目的:为解决抗击新型冠状病毒疫情时医生穿着防护服无法听诊的问题,研制隔离式无线电子听诊器。方法:采用低噪声音频放大、高频采样、高精度模数转换和不锈钢一体成型听诊器体件等技术提升音频质量;定制不自动关机的蓝牙耳机,可自动回连听诊器,解决穿着防护服时蓝牙耳机自动关机后开机难的问题。结果:隔离式无线电子听诊器在武汉火神山医院、湖北省妇幼保健院光谷院区、上海市公共卫生临床中心等医院进行了临床应用,在新冠肺炎的日常诊察中收到良好反馈。结论:隔离式无线电子听诊器可满足医生穿着防护服条件下的听诊需求。

Objective An isolated wireless electronic stethoscope was developed to solve the problem that doctors cannot auscultate in personal protective equipment(PPE)during the COVID-19 outbreak.Methods The development adopted low-noise audio amplification,high-frequency sampling,high-precision analog-to-digital conversion,and stainless-steel unibody design to improve the audio quality.In order to solve the problem of difficulty in turning on the Bluetooth headsets after automatic power off when the doctors are wearing PPE,we customized the Bluetooth headsets without the setting of automatically power off.Results The isolated wireless electronic stethoscope has been clinically applied in Huoshenshan hospital in Wuhan,GuangGu branch of Hubei Maternal and Child Healthcare Hospital,Shanghai Public Health Clinical Center and other hospitals,receiving good feedback from doctors at front line.Conclusion The isolated wireless electronic stethoscope can meet the needs of auscultation when the doctors are wearing PPE.
