A drug delivery device for intraocular liquid delivery is presented in which a second actuation member of the drug delivery device is configured to axially block a plunger rod and/or a first actuation member of the drug delivery device, wherein the second actuation member is to be actuated to axially release the plunger rod and/or the first actuation member such that the first actuation member can be actuated. The dosing device includes a securing member configured to block rearward movement of the plunger rod and/or one of the first actuating members at least in an initial position and/or a dosing position of the plunger rod, and wherein the securing member is configured to block actuation of the second actuation component prior to reaching the dosing position of the plunger rod. 本发明提出一种用于眼内液体给药之给药装置，其中该给药装置之一第二致动部件经构形以轴向阻挡该给药装置之一柱塞杆及/或一第一致动部件，其中该第二致动部件将经致动以轴向释放该柱塞杆及/或该第一致动部件使得可致动该第一致动部件。该给药装置包括一固定构件，其中该固定构件经构形以至少在该柱塞杆之一初始位置及/或一给药位置中阻挡该柱塞杆及/或该第一致动部件之一向后移动，且其中该固定构件经构形以在到达该柱塞杆之该给药位置之前阻挡该第二致动部件之致动。
