移动DR设备Wi-Fi遥控延时曝光装置的设计与应用

Design and Application of Wi-Fi Remote Control and Time-delay Exposure Device for Mobile Digital Radiography Equipment

目的本研究针对移动DR设备提出一种Wi-Fi遥控延时曝光装置,以避免医护人员受X射线的照射、提高移动DR的工作效率。方法用市场上较为普及的智能手机发送曝光指令,用Wi-Fi传输遥控信号,用单片机控制延时时间,实现一键Wi-Fi遥控延时曝光。结果当在手机APP上发出曝光指令,蜂鸣器立即报警,提示患者做好闭气等准备工作;2 s后移动DR设备的预备档吸合,3.5 s后曝光档吸合,4.5 s后完成X射线摄片,同时蜂鸣器停止报警。遥控信号稳定,延时控制精确。结论该装置相较于传统的移动DR设备曝光装置,具有工作效率高、性能稳定和更加安全等优点,有较好的推广应用价值。

Objective To design a Wi-Fi remote control and time-delay exposure device for mobile digital radiography(DR)equipment,in order to avoid medical staff from X-ray exposure and improve the work efficiency of mobile DR.Methods The exposure command was sent by the popular smart phone in the market,the remote control signal was transmitted by Wi-Fi,and the delay time was controlled by single chip microcomputer,so as to realize one touch Wi-Fi remote control and delayed exposure.Results When the exposure instruction was sent by the mobile APP,the buzzer would give an alarm immediately to remind the patients to make preparations such as closing the breath.After 2 s,the ready signal arrived to mobile DR equipment.3.5 s later,the exposure signal arrived to mobile DR equipment,and 4.5 s later,the exposure was completed and the buzzer stopped alarming at the same time.The remote control signal was stable and the delay control was accurate.Conclusion Compared with the traditional exposure device of mobile DR equipment,this device has the advantages of high efficiency,stable performance and more security,and has a good application value.
