    • The invention relates to a device for dispensing a fixed dose of fluid, the device comprising at least one barrel; at least one plunger at least partially enclosed within the barrel; a motion conversion mechanism for transferring actuated pressure force applied outside the barrel into movement of the at least one plunger in a dispensing direction, wherein the motion conversion mechanism comprises at least one rotating gear; and a releasing mechanism for disconnecting the plunger from the motion conversion mechanism, wherein at a released position the at least one plunger can move in a direction opposite to the dispensing direction, independent of a rotational movement of the at least one gear, and wherein the movement of the plunger in the opposite direction to the dispensing enables loading the fluid into the barrel.
    • 本发明涉及一种用于分配固定剂量的流体的装置,该装置包括至少一个桶; 至少一个柱塞至少部分地封闭在所述筒体内; 运动转换机构,用于将施加到所述筒外部的致动压力传递到所述至少一个柱塞在分配方向上的运动,其中所述运动转换机构包括至少一个旋转齿轮; 以及用于将活塞与运动转换机构分离的释放机构,其中在释放位置,所述至少一个柱塞可以在与所述分配方向相反的方向上移动,而与所述至少一个齿轮的旋转运动无关,并且其中 柱塞在与分配相反的方向上的运动使得能够将流体装载到筒中。
