摘要： An injection device (10) comprises an injection solution receptacle (30) and a plunger (70) at feast a portion of which is slidably received in the injection solution receptacle (30), wherein the plunger (70) is displaceable relative to the injection solution receptacle (30) in a distal direction in order to expel an injection solution contained in the injection solution receptacle (30) from the injection solution receptacle (30). A first plunger stop mechanism (140) is adapted to stop a displacement of the plunger (70) relative to the injection solution receptacle (30) in the distal direction at a first dosing position (P1). A second plunger stop mechanism (140) is adapted to stop a displacement of the plunger (70) relative to the injection solution receptacle (30) from the first: dosing position (P1) in the distal direction at a second dosing position (P2), wherein the first and the second dosing position (P2) of the plunger (70) are selected in such a manner that the plunger (70), upon being displaced relative to the injection solution receptacle (30) between the first and the second dosing position (P2) is adapted to expel a desired dose of the injection solution contained in the injection solution receptacle (30) from the injection solution receptacle (30).

摘要： The present disclosure relates to an injection device, in particular a micro dose injection device such as, for example, an ophthalmic injection device. An example device comprises a rotatable plunger; a solution receptacle having a first end configured to slidably receive the rotatable plunger and a second end configured to dispense solution contained in the solution receptacle; a first stop member configured to prevent the rotatable plunger from being slidably displaced to a second position while the rotatable plunger is at a first position and in a first orientation; and a second stop member configured to prevent the rotatable plunger from rotating in a first direction about the first axis while the rotatable plunger is at the first position and in the first orientation, wherein slidably displacing the rotatable plunger from the first position to the second position dispenses a quantity of the solution contained in the solution receptacle.
