MEDICAL INJECTION SYSTEM COMPRISING A MEDICAL INJECTION DEVICE AND A DOSE LIMITER MODULE

The present invention relates to a medical injection system comprising a medical injection device (100) of the type comprising a rotatable dose setting member (160). The system further comprises a dose limiter module (200) adapted for being releasably coupled to the injection device (100). The dose limiter module (200) comprises a dose limiter base (201) and a limiter (240) arranged relative to the dose limiter base (201) so that their relative position is adjustable to set an adjusted dose limiting position. When the dose limiter module (200) is coupled to the injection device (100), the limiter (240) cooperates with the dose setting member (160) to define a blocking means for preventing rotation of the dose setting member (160) beyond the adjusted dose limiting position. The dose limiter module (200) further comprises a user operable lock (210,212,232,223,243) configured for operation between a locked state and an unlocked state to respectively prevent and enable modification of the adjusted dose limiting position, the lock (210,212,232,223,243) being configured for maintaining the lock in the locked state at least when the dose limiter module (200) is not coupled with the injection device (100).
