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.
