无线氧浓度监测装置的设计

Design of wireless oxygen concentration monitoring device

目的 :针对现有的氧浓度监测装置的弊端与不足,设计一种无线氧浓度监测装置。方法 :该装置主要由氧气传感器、氧气传感器连接线、氧浓度监测主机、显示终端4个部分组成。以HT67F489为主控制芯片,采用KE-25氧浓度传感器采集氧气体积分数数据,再通过T82模块将该数据无线传输到显示终端的App软件上。结果:该装置监测的氧气体积分数与设备自带监测装置的氧气体积分数监测值一样精确,不仅减少了患者用氧安全隐患,而且可以使医学工程人员在最短的时间内发现用氧设备的故障,缩短排查时间。结论:该装置安装简单、系统性能稳定、监测氧气体积分数精确度高,可以不受物理环境的影响实现对各种医用用氧设备氧气体积分数的实时监测,具有重大的社会效益和军事效益。

Objective To design a wireless oxygen concentration monitoring device to solve the existing problems. Methods The device was composed of an oxygen sensor, an oxygen sensor line, an oxygen concentration monitoring host and a display terminal. HT67F489 was used as the main control chip, KE-25 oxygen concentration sensor was applied to collecting oxygen concentration data, and then through the T82 module wireless transmission of the data was executed to the display terminal of the App software. Results Clinical trials proved the measure value by the device was the same to that by the equipped meter,which facilitated the medical engineer find the faults in the shortest time. Conclusion The device gains advantages in easy installation, stable performances, high accuracy and anti-interference against physical environment, and thus has high social and economic benefits.
