LOCKING AND RETAINING MECHANISM FOR THE NEEDLE GUARD SLEEVE OF AN INJECTION DEVICE

摘要

Injection device having a mechanism for automatically discharging a product, further comprising a housing (1), a needle guard (9) at the distal end of the injection device, which needle guard (9) can be moved from its initial position into a proximal end position into the housing (1) and optionally from the proximal end position into a needle-guarding position, an activation mechanism (13) which can be moved from a non-activated position into an activated position, and when the needle guard (9) is in the non-activated position it is blocked in its ability to be moved into the proximal end position and when it is in the activated position can be moved into the proximal end position, wherein a resiliency arranged locking means (50, 50b) and a transmission means (51) which tenses and deflects the locking means (50; 50b) from a first position into a second position and is during the movement of the activation mechanism (13) into the activated position.
