| titleOfInvention | Injection device |
| abstract | An injection device for delivering a dose of medicament from a syringe ( 5 ), the injection device comprising a housing ( 10 ), a plunger ( 210 ) moveably mounted within the housing ( 10 ), an actuation mechanism ( 200 ), a trigger mechanism ( 40 ), and a plunger velocity regulator. The actuation (mechanism ( 100 ) is arranged to provide a forward biasing force to urge the plunger ( 210 ) forward in use to express a dose of medicament, and the trigger mechanism ( 40 ) is arranged to releasably hold the plunger ( 210 ) against the force of the actuation mechanism ( 200 ). The plunger velocity regulator comprises a cam surface ( 262 ) associated with the housing, and a cam member ( 252 ) associated with the plunger ( 210 ) and arranged to engage the cam surface ( 262 ) during actuation movement of the plunger ( 210 ) such that axial movement of the plunger ( 210 ) relative to the housing ( 10 ) causes relative rotational movement of the cam member ( 252 ) which limits the forward velocity of the plunger movement. The plunger ( 210 ) is axially connected to the cam member ( 252 ) by a releasable coupling ( 300 ), and the plunger velocity regulator further comprises a coupling member ( 350 ) which blocks release of the releasable coupling ( 300 ) when the plunger ( 210 ) is in a rearward position and wherein forward movement of the plunger ( 210 ) moves the releasable coupling ( 300 ) out of engagement with the coupling member ( 350 ) such that the plunger ( 210 ) may disengage the cam member ( 252 ) after an initial movement of the plunger ( 210 ). |
