摘要：
An autoinjector comprising: (a) a cartridge unit (1 101 201 301 501 601) comprising: a housing (20 120 220 320 520 620) of cartridge unit defining a housing cavity cartridge unit and an opening projection needle said housing cavity cartridge unit is disposed and for receiving a syringe (10 110 210 310 510) comprising: a cylinder (12 112 212 312 512) for containing a volume of a liquid drug formulation a hollow needle (14 114 214 314 514 614) at a forward end of said cylinder, said hollow needle defines a needle tip (15 115 215 315 515 615) for dispensing said liquid drug formulation and a plunger (18 118 218 318) which is axially movable within the cylinder a removable cap ((50 150 250 350 550 650) that fits over, and thereby acts to close, the opening projection needle, and connecting said removable cap, a cap (17, 19 117, 119 217, 219 317, 319) needle defines a needle sheath for sheathing said needle tip, and (b) a drive unit (70, 170) comprising: a housing (71) of unit pulse defining a cavity coupling and administration port needle, wherein said cavity coupling is provided for receiving in coupling the cartridge unit in a docking position on which said cartridge unit and / or said syringe being movable from a rest position in which the needle tip of the syringe is within the housing of drive unit, to a use position in which the needle tip protrudes from said delivery opening needle , and a provision of impulse that provision pulse comprises: one or more sources of electrically powered axial thrust a first transfer pulse (82b 179) for transferring said axial cartridge unit and / or the syringe to advance the syringe to said use position pulse and a second transfer pulse (83c 187) to subsequently transfer the axial thrust to said syringe plunger to move the plunger into the cylinder of the syringe for ejecting at least part of said volume of formulating liquid drug characterized in that the drive unit is provided with a timer (1090) which begins counting time with
