参照图1，本实用新型装置的结构是，包括水剂瓶5和安装在水剂瓶5封口端的水针座双头针7，水粉混液前，水针座双头针7中的短针头不穿透水剂瓶5的封口，水粉混液时，水针座双头针7中的短针头才穿透水剂瓶5的封口，在水剂瓶5的瓶底端套装有水剂瓶托12，在水剂瓶5的瓶体外圆套装有弹簧11；在水剂瓶5、弹簧11、水剂瓶托12的外圆周套装有水剂套筒3，水剂套筒3的一端开有轴心孔，水针座双头针7中的长针头从该水剂套筒3的轴心孔伸出，水剂套筒3的另一端连接有旋盖2，旋盖2的轴心通孔中穿入推杆1，推杆1的内端与水剂瓶托12的外端头套装连接；水剂套筒3的外表面套装有粉剂套筒6，粉剂套筒6的一端连接有指托4，指托4的位置处于水剂瓶5的中段，粉剂套筒6的另一端内腔安装有粉针瓶9，粉针瓶9朝向水针座双头针7长针头的一端设置有活塞8，存储状态时，水针座双头针7中的长针头不穿透活塞8，混液时及注射状态时，水针座双头针7中的长针头则穿透活塞8，粉针瓶9的另一端伸出粉剂套筒6并安装有粉针座双头针10，在混液前，粉针座双头针10中的短针头不穿透粉针瓶9的封口，注射状态时，粉针座双头针10中的短针头才穿透粉针瓶9的封口，粉针座双头针10中的长针头则扎入人体实施注射。
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。
参照图6，推杆1的圆柱环周上纵向开有卡槽一14，卡槽一14朝向水剂套筒3的一端开有周向的卡位一13。
参照图7，旋盖2的底面圆型孔的直径对应的内表面设置有一对卡扣一15，卡扣一15的宽度以在卡位一13、卡槽一14中滑动为宜。
如图8所示，为水剂套筒3及其卡槽二17、卡位二18的结构示意图。水剂套筒3的一端外表面设置有与指托4相配合的外螺纹，水剂套筒3的另一端为缩小直径的圆周结构，该缩径处内表面的凸肩用于顶撑弹簧11，弹簧11的另一端顶在水剂瓶托12环形端面上。
如图9所示，为指托4及卡扣二16的结构示意图。指托4轴心开孔设置有内螺纹，内螺纹的直径两端设置有一对卡扣二16。
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。
将旋盖2套到推杆1上时注意将旋盖2上的卡扣15通过按钮的卡槽一14旋到卡位一13上，注射前必须将旋盖上的卡扣一15转到推杆1的卡槽一14上。
第四步，将粉针瓶9和第三步之前装好的部件依次装入到粉剂套筒6中，将指托4的卡扣二16对准水剂套筒3的卡槽二17，并旋转到卡位二18后，指托4旋到粉剂套筒6上的螺纹。
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。
