水剂套筒3与旋盖2通过螺纹连接,粉剂套筒6与指托4通过螺纹套接。
推杆1的移动距离稍大于水剂瓶5密封口部与水针座双头针7的预留距离,以便于水针座双头针7中的针头短端能够插入水剂瓶5密封口内。
水剂套筒3的移动距离稍大于水针座双头针7与活塞8预留距离加活塞8移动距离的和,以便于水针座双头针7中的针头长端能够穿过活塞8深入粉剂瓶9内。
参照图2、图3、图4、图5,分别是本实用新型装置的几个外观视图,其中的图2是图1的前视示意图;图3是图1的右视示意图;图4是图1的俯视示意图;图5是图1的仰视示意图。
参照图6、图7、图8、图9,分别是本实用新型装置的几个部件结构示意图。

本实用新型装置的装配及使用过程是,
第一步,如图10所示,将粉针座双头针7卡装到水剂瓶5开口端,粉针座双头针7中的粉针座为透明材料制作而成,方便看到针头卡的位置。存储状态时,该针头不能穿透水剂瓶5的瓶塞,水剂瓶5中装有溶媒并预充有气压。如果提前将针插入水瓶内会造成泄压,水瓶内溶媒无法流出。
第二步,如图11所示,在水剂瓶5外周及底端上套装弹簧11和水剂瓶托12。
第三步,如图12所示,将前两步装好的部件装入水剂套筒3中,将旋盖2套到推杆1上,然后在水剂套筒3上装上推杆1,并将旋盖2旋到水剂套筒3上拧紧。

第五步,如图13所示,将旋盖2和指托4上的卡扣从各自的卡位中旋到卡槽内,沿卡槽向下推动推杆1,注意,必须使推杆1处于整个装置的上方位置,保证水剂瓶5中的溶媒在预充气压的作用下,靠气压压迫到粉针瓶9中,如果倒置会造成泄压,其中的溶媒无法流到粉针瓶9内。
第六步,摇晃注射器,使药液充分溶解。
第七步,如图14所示,在粉剂套筒6前端装上粉针座双头针10,注意粉针座双头针10中的长针头向上,粉针瓶9里面的气压泻出,并推动推杆1使粉针瓶9里面的空气排尽,准备注射。
第八步,实施注射,活塞8被推到粉针瓶9开口端尽头,将粉针座双头针10中的长针头插入患者肌体内,注射液有效排出进入患者体内,注射操作完成后,如图15所示。
