    • The invention relates to a gearing mechanism for a dose delivery device wherein the dose can be set by rotating a dose setting member (2, 102), and by which the dose setting member (2, 102) and a push-button (4) elevates from one end of the device proportional to the set dose from a position fixed relative to a housing (1, 101), and by which an injection of the set dose can be done by pressing the push-button back to its not elevated position, moving a piston rod (10, 110) cooperating with the piston in an cartridge (12, 112) and expelling a medicament out of the through a needle. The gearing mechanism is arranged in the device in such a way, that the loss of energy is very low.
    • 本发明涉及一种用于剂量递送装置的齿轮机构,其中剂量可以通过旋转剂量设定构件(2,102)来设定,并且剂量设定构件(2,102)和按钮(4) 从与设定剂量成比例的装置的一端从相对于壳体(1,101)固定的位置升高,并且通过该按压按钮将按钮重新按压到其未升高的位置 移动与活塞在药筒(12,112)中配合的活塞杆(10,110),并将药物排出穿过针头。 齿轮传动机构以这样的方式布置在装置中,即能量的损失非常低。
