Title:
薬物送達デバイスのためのドライブアセンブリ
Document Type and Number:
Japanese Patent JP6417393
Kind Code:
B2
Abstract:
A drive assembly for a drug delivery device includes a drive mechanism comprising a piston rod and a drive member to drive the piston rod to dispense a dose of drug and a dose member coupled to the drive member. The assembly further comprises a return mechanism comprising a spring member. The assembly further comprises a movable member which is coupled to the spring member. In a setting, the movable member is coupled to the dose member and, the movable member is movable from an initial position to a dose set position, thereby biasing the spring member. In the dispensing, the drive member and the movable member are decoupled such that the drive mechanism is operable by the user by application of a driving force to the drive mechanism, wherein the spring member of the return mechanism drives the movable member independently of the driving force towards its initial position.
