野战X线机多体位三脚支架的研制

Development of multi-body-position tripod of X-ray apparatus for field battle

目的:研制新型野战X线多体位三脚支架,解决原有支架投射角度受限问题。方法:在原三脚架中轴支撑杆的下端增加1个固定螺杆,用于倒置固定球管,实现球管垂直向下投照,同时加长3个支脚。结果:新型三脚支架上的X线机可对立位、卧位患者进行投照;增大了焦片距调节范围,完全满足一般摄片要求。新增加的固定螺杆固定牢靠,所承受的质量远大于X线机球管的质量;整机重心相对降低、底边长度增宽;质量及总长度增加不明显,未影响便携性。结论:新型野战X线机多体位三脚支架符合野战实际需要。

Objective To develop new-type multi-body-position tripod of X-ray appratus for field battle.Methods One screw was added to the bottom of axis stayer of the original tripod for the inversion of fixed bulb so that the bulb could vertically project.Three support feet were porlonged at the same time.Results The X-ray appratus of the new-type multi-body-position tripod could project for patients in satnding or lying position and the range of focus adjustmet was enlarged,which could meet nomal requirements.The new-added crew was firm and its support quality was greatly over the quality of X-ray appratus.Compared with the original one,the barycenter of the appratus was lower,and the hemline length was longer.It remaind portable for the overall quality and length didn＇t change apparantly.Conclusion The new-type multi-body-position tripod of X-ray appratus for field battle meets the practical field requirments.
