IPC: A61M5/315
Filed: 2021-10-08
Abstract: A drug delivery device 100 comprising a housing containing a syringe 106 with a plunger 109, the plunger comprising a first guide surface 115 abutting a second guide surface 114 within the housing at a non-perpendicular angle relative to a longitudinal axis of the plunger.
