婴幼儿放射检查防护和固定装置设计与临床应用

Development and Clinical Application of Protective and Fixation Device for Infant Radiology Examination

目的:介绍一种应用于婴幼儿的CT和普通X线摄影的放射检查防护和固定装置及其在临床中的应用。方法:本装置主要由检查床上的3块倒U形含有0.5 mm铅当量的有机铅玻璃罩和含有凹陷的3块垂直铅挡板组成,形成一个相对独立的空间,通过调节倒U形有机铅玻璃罩的相对位置和垂直铅挡板,对应不同的照射野,以达到防护目的。结果:通过使用此检查防护与固定装置,可明显减少非检查部位X线的照射剂量,患儿放射检查成功率提高到98%以上。结论:此装置操作简单、快捷、安全舒适,是适用于婴幼儿的放射检查防护与固定装置。

Objective To develop and apply a new protective and fixation device for infant CT and X-ray examinations.Methods The device was composed of three pieces of inverted-U 0.5 mm lead glass,three vertical lead baffles and an examining table,which formed a relatively independent space and different exposure fields by regulating the position of the glass and the baffles.Results The device could reduce the radiation dose of the non-target site,and the success rate for infant radiology examination was increased to 98％ or more.Conclusion The protective and fixation device for infant radiology examination is easy to operate,convenient and safe,and thus worth popularizing clinically.
