Abstract:
1. A device for delivery of medicament, comprising: a main housing; a multi-chamber container, comprising a first chamber containing a diluent, a second chamber containing a medicament agent, a bypass channel, an outlet provided with a mechanism to be connected to a medicament delivery member, and at least one longitudinally movable plunger; a pre-treating arrangement acting on at least one longitudinally movable plunger for mixing the medicament agent with the diluent and obtaining a mixed medicament; a drive force mechanism configured to act on a longitudinally movable plunger rod capable of exerting a force on the container for delivering the mixed medicament; and an activating delivery mechanism configured to act on the drive force mechanism for initiating the delivering of medicament via the medicament delivery member; wherein the pre-treating arrangement comprises a clickable mechanism resiliently and operably connected to a longitudinally movable second rod that is partially and slidably arranged inside the longitudinally movable plunger rod such that the clickable mechanism is adapted to be manually and intermittently activated for stepwise pushing the second rod inside the container and thereby mixing the medicament agent with the diluent.
