儿童多功能性无线听诊器的研制
Development of children's multifunctional wireless stethoscope
摘要
Abstract
At present,the children's stethoscope on the market has problems such as unable to save the auscultation data,limited transmission distance,low auscultation volume,large temperature difference of the pickup head,obvious interference from external noise,residual virus and bacteria of the stethoscope,and inability to mobilize the respiratory enthusiasm of children.In order to solve the above problems,this study designed a children's multifunctional wireless stethoscope,which selected KYFYY master chip to control the data transmission between modules,and realized the visualization of heart sound signals by using KY1933 biological signal acquisition and analysis system.Wireless Bluetooth was used to transmit the heart sounds of the children,Bluetooth technology was used to pair with the radio device,and the amplification device carried by the stethoscope expanded the heart sounds and lung sounds of the children.The heating device was used to heat the pickup head.The noise reduction device was used to reduce external noise and avoid interference.The disinfection device was used to eliminate bacteria and viruses on the surface of the microphone head.The detachable windmill was used to motivate the child to breathe.关键词
