HAND-HELD MANUAL INJECTOR

摘要

A hand-held manual injector (10, 110) comprises a support portion (60, 160) for receiving a barrel (72) of a syringe (70) or cartridge and a body (12, 112) with a pusher rod (16, 116). The pusher rod (16, 116) can be advanced through the body (12, 112) towards the syringe support portion (60, 160) by manual actuation of a lever (26, 126), which activates a friction drive mechanism (14, 114). The syringe support portion (60, 160) is adapted to retain the syringe barrel (72) and prevent it from moving longitudinally during an injection. This is done by having flanges (74) on the syringe barrel (72) fit into a slot (66, 166a, 166b, 166c) on the support portion (60, 160).
