摘要： The invention features an injection device for needles injection. To inject a drug into the body, the oriface (13) of the syringe assembly is pressed against the skin. Thumb pressure is then used to press an injection button (7). This action locks the button in position at detents (16), actuator (4) seats against the chamered end of opening (11). When gas reservoir (6) hits the pointed end of the actuator (4), a seal is ruptured in reservoir (6) thereby releasing the compressed gas contained therein. The gas escapes through the actuator (4) and into an opening (11) where it impinges upon the bottom of floating plunger (10). The plunger (10) pushes against mated pistons (9a, b) thereby expelling the drug through the oriface (13) and into the skin. The entire injection process is completed in less than 2 seconds.

摘要： An injection device (5) includes a housing (30) having a proximal end and a distal end, the housing (30) defining a distal opening, and a first opening (7) in a side of the housing and between the proximal and distal ends; a propellant (90) disposed inside the housing (30) and spaced from the distal end; and a movable member (100) disposed inside the housing (30) and between the distal end and the propellant (90), wherein the propellant (90) is in fluid communication with the movable member (100) and the first opening (7).

摘要翻译： 本发明的特征在于用于注射针头的注射装置。 为了将药物注入体内，将注射器组件的口眼（13）压在皮肤上。 然后用拇指按压按下注射按钮（7）。 此动作将按钮锁定在定位器（16）处，致动器（4）座靠着开口（11）的开口端。 当气体储存器（6）撞击致动器（4）的尖端时，储存器（6）中的密封件破裂，从而释放其中包含的压缩气体。 气体通过致动器（4）逸出并进入开口（11），在该开口处冲击浮动柱塞（10）的底部。 柱塞（10）推动配合的活塞（9a，b），从而将药物通过孔口（13）排出并进入皮肤。 整个注射过程在不到2秒的时间内完成。
