目前,临床上开展脑血管造影检查的单位越来越多,但国内尚无一种专门用于脑血管造影的全自动装置出售。虽有CT应用于临床,但仍取代不了脑血管造影检查,且CT昂贵,大多数单位无法购买。所以不少单位仍处于用手推药、拉片状态,致使造影效果不满意,且影响工作人员身体健康。我们自1984年开始,反复探索、设计、研制出全自动脑血管造影机,它包括三大部分;(1)自动加压注射器;(2)自动曝光装置;(3)自动换片装置。该机全部采用机械电控原理制作。具有体积小,造价低,原材料容易获得,结构简单,制作容易,工作原理简明,操作方便,易掌握等优点,可与国内任何200mA以上X光机连接使用,整个操作在
At present, there are more and more clinical units for cerebrovascular angiography, but there is not a fully automatic device for cerebral angiography in China. Although CT used in clinical, but still can not replace cerebral angiography, and CT expensive, most units can not be purchased. Therefore, quite a few units are still in the state of pushing their hands and pulling tablets. As a result, the radiographic findings are not satisfactory and the health of the staff members is affected. We have been exploring, designing and developing automatic cerebrovascular angiography machines since 1984, which consists of three major parts: (1) auto-pressurized syringes; (2) automatic exposure devices; and (3) automatic transfer devices. This machine uses the principle of mechanical and electrical control production. The utility model has the advantages of small volume, low cost, easily obtained raw materials, simple structure, easy manufacture, simple working principle, convenient operation and easy control, and can be connected with any X-ray machine of over 200mA in China.
