无线电子恒温式听诊头的研制

Development of Wireless Electronic Isothermal Stethoscope Head

本文介绍一种新型恒温式听诊头。通过改造听诊器胸件,增加加温装置实现听诊头的恒温。其原理是,采用外置的无线发射模块通过发射线圈发射电磁波,发出的电磁波被胸件内的接收线圈接收并转化为热能来控制听诊头保持恒温。

A new kind of isothermal stethoscope head is introduced in this paper. Transform the chest piece of a stethoscope, add warming device to keep stethoscope head isothermal. The principle is that the wireless module outboarded transmits electromagnetic wave by coil, which is accepted by receiving coil in the chest piece, and then transformed into heat to keep head isothermal.
