Gearing mechanism for an injection device
Abstract:
An injection device comprising: a base member (102); a plunger (104) for driving a piston in a distal direction; a driving member (106); and a gear mechanism (108) providing a gearing between the driving member (106) and the plunger (104) such that then the driving member (106) is moved at a first speed relative to the base member (102), the plunger (104) is moved at a second speed relative to the base member (102); wherein at least two of the base member (102), the plunger (104) and the driving member (106) are pivotally connected to the gear mechanism (108).
Abstract(Chinese):

一种注射装置，包括：基底构件（102）; 用于沿远端方向驱动活塞的活塞（104）; 驱动构件（106）; 以及齿轮机构（108），其在所述驱动构件（106）和所述柱塞（104）之间提供齿轮传动，使得所述驱动构件（106）相对于所述基座构件（102）以第一速度移动，所述柱塞 104）以相对于所述基座构件（102）的第二速度移动; 其中所述基座构件（102），所述柱塞（104）和所述驱动构件（106）中的至少两个可枢转地连接到所述齿轮机构（108）。
