请参阅图 3，溶质瓶外套 2为上小下大的阶梯套，细套上端部设置成公螺口， 而且细套内还设有两个针帽卡点 22，该两个针帽卡点 22上设有针帽 21，该针头 6固设于针帽 21。 请参阅图 1以及图 2 ,该溶媒瓶外套 4下端设置成母螺口，该母螺口和溶盾 瓶夕卜套 1的公螺口相螺接，以使得溶质瓶外套 2和溶某瓶外套 4之间构成可拆卸 连接结构，也既是注射器主体和溶媒瓶外套 4之间构成可拆卸连接结构。根据需 要还可在溶媒瓶外套 4上设有用于观察溶媒瓶 3内溶媒是否被全部注入溶质瓶 1 的观察口。
请参阅图 1、 图 2以及图 3， 溶媒瓶外套 4套设溶媒瓶 3， 且溶质瓶 1瓶口 与溶媒瓶 3瓶口正相对。溶质瓶 1瓶口与溶媒瓶 3瓶口之间设有笫二推进机构 5, 第二推进机构 5包括第一连接槽 51、一档推套 52、第二连接槽 53以及二档推套 54。
请参阅图 6 , 第一连接槽 51开设在外套 4内周面， 包括两第一轴向滑动槽 511以及两第一横向滑动槽 512 , 第一横向滑动槽 512连通第一轴向滑动槽 511 下开口。 第二连接槽 53也开设在外套 4内周面， 包括两第一轴向滑动槽。
请参阅图 4 , 一档推套 52对称向外凸设有两第一凸块 521， 该两第一凸块 521分别可滑动连接于两第一连接槽 51 , 使得该一档推套 52和溶媒瓶外滑 4内 周之间构成先滑动后转动连接关系。 该一档推套 52顶面向上凸设有螺旋状的变 向部 522 ,该一档推套 52顶面还向下凹设有突降槽 523,上述的突降槽 523邻接 于变向部 522。
请参阅图 5，二档推套 54对称向外凸设有两第二凸块 541， 两第二凸块 541 分别可滑动连接于第二连接槽 53 (第二轴向滑动槽）， 使得该二档推套 54和溶 媒瓶外滑 4内周之间构成滑动连接关系。 该二档推套 54底面向下凸设有螺旋状 的落人部 542。
请参阅图 1以及图 2,—档推套 52以及二档推套 54均套设于外套 4内，一 档推套 52靠于针帽 21之上， 二档推套 54靠在溶媒瓶 3瓶口之下。 上述的落入 部 542和变向部 522配合构成可变相对滑动为相对转动的变向机构。在未混合之 前或混合前阶段 (可参考下面混药步骤理解）， 落入部 542靠接在变向部 522之 上， 混合过程中当二档推套 54可转动但不可滑动时变向机构工作， 落入部 542 和变向部 522相对转动后， 落入部 542落入突降槽 523, 二档推套 54向一档推 套 52方向滑动。
请参阅图 1以及图 2，针头 6位于溶盾瓶 1瓶口和溶媒瓶 3瓶口之间，并可 滑动穿过一档推套 52及二档推套 54„
请参阅图 1以及图 2 , 溶某瓶外套 4顶端设置有可装拆的外套盖 41。 该第 一推进机构 7设于溶媒瓶 3的推塞 31之上， 其包括一旋钮 71、一推杆 72、一弹 簧套 73以及一弹性体 74。
请参阅图 1以及图 2， 旋钮 71向外凸设有抵靠部 711， 且底面凸设有上斜 坡 712。该旋钮 71套接在外套 4内，上部从下往上穿过外套盖 41，且抵靠部 711 抵靠在外套盖 41下表面， 则使得旋钮 71可相对外套盖 41转动， 且还可防止旋 钮 71脱离于外套盖 41外。
请参阅图 1、 图 2以及图 7 , 推杆 72主体横截面成长方形， 中上部向内凹 设成开关槽 721 , 下部向外凸设成凸环 722， 底端靠接溶媒瓶 3的推塞 31之上。 该推杆 72顶部不可相对转动连接于旋 ¾ 71。
请参阅图 1、 图 2以及图 8 , 弹簧套 73上端设有固定板， 固定板顶面凸设 有下斜坡 732， 上述的上斜坡 712吻合并靠接在下斜坡 732之上。 固定板上还开 设有长方形的锁接通槽 731 ,上述的推杆 72穿过弹簧套 73而且上端穿过锁接通 槽 731。
请参阅图 1以及图 2 , 弹性体 74套接推杆 72并介于凸环 722与弹簧套 73 固定板之间； 该推杆 72的开关槽 721卡设在弹簧套 73的锁接通槽 731以储能， 转动推杵 72可使开关槽 721脱离锁接通槽 731以释放弹性体 74弹能。上述的开 关槽 721和锁接通槽 731配合形成开关机构。上述的弹簧套底面靠接卡式瓶顶端， 推杆靠接推塞之顶面。
混药装置的混药步骤为：
Pl、 转动旋钮 71 , 旋钮 71的上斜坡 712和弹簧套 73的下斜坡 732相配合 以使弹簧套 73具有向下的推力， 该推力顶抵溶媒瓶 3 (卡式瓶）向下滑动（向 溶质瓶 1方向滑动）， 同时当旋钮 71转动到一定角度后推杆 72截面长方形长度 和锁接通槽 731长方形长度相平行，则开关槽 721脱离弹簧套 73的锁接通槽 731， 于是弹性体 74释放弹性能并产生弹力， 该弹力推动推杆 72向下滑动， 推杆 72 推动推塞 31相对卡式瓶也向下滑动， 使得卡式瓶内的空气具有较高的气压， 当 气压达到一定程度后， 该弹力推动推塞 31和卡式瓶向下滑动， 在第一轴向滑动 槽 511和第二轴向滑动槽的作用下一档推套 52以及二档推套 54也向下滑动，一 档推套 52压下设于针帽卡点 22之上的针帽 21,使得针帽 21固定卡设于注射器 主体的针帽卡点 22, 并使得针头 6下端刺穿溶质瓶 1瓶塞以导通溶质瓶 1;
P2、当一档推套 52滑动到第一横向滑动槽 512时，继续转动旋钮 71使得溶 媒瓶 3继续向下滑动（继续向溶质瓶 1方向滑动）， 在变向机构的作用下一档推 套 52和二档推套 54之间相对转动，接着落入部 542落入突降槽 523, 二档推套 54相对一档推套 52向下滑动， 溶媒瓶 3也向下移动使得针头 6上端刺穿溶媒瓶 3瓶塞以导通溶媒瓶 3 , 同时弹性体推动推塞 31使其内的溶媒 ¾t£注入溶质瓶；
P3、从溶媒瓶外套 4上拆卸下注射器主体， 该注射器主体上带有针头， 也既 是完整注射器。
本发明的其它具体结构可参照本申请人在 2005年 09月 14曰申请了发明名 称为 "粉针剂自动混药装置" 的发明。
