Abstract: An injection device is presented having a housing, a container holder, a first and a second energy accumulating member arranged in the interior of the housing adapted to accumulate and store energy, a sleeve, a plunger holder operationally associated with said first energy accumulating member such that the plunger holder and the container holder are axially moveable in relation to the housing a predetermined distance towards the proximal end of the injection device from an initial position to a position following needle penetration, and a plunger rod being operationally associated with said second energy accumulating member such that the plunger rod is axially moveable in relation to the container holder, wherein in the initial position movement of the plunger holder is substantially inhibited by at least one first biasable member that recoils when being overlapped by an opening and/or recess of the sleeve such that the plunger holder is released.

Abstract: A medicament delivery device is provided having a power body having opposite proximal and distal ends, a plunger rod driver coaxial and movably arranged in relation to said power body, a plunger rod coaxial and movably arranged in relation to said plunger rod driver, a force spring element operably connected between the plunger rod and the power body The plunger rod driver has a first holding elements arranged to interact with second holding elements on the plunger rod and with the power body for releasably holding the plunger rod with the force spring element in an injection tensioned state.

Abstract: An injection device has a container holder in a medicament container housing; first and second energy accumulating members in the housing; a slidable sleeve; a plunger holder associated with the first energy accumulating member such that the plunger holder and container holder are axially movable toward a proximal end of the device from an initial position to a position following needle penetration; and a plunger rod operationally associated with the second energy accumulating member such that the plunger rod is axially movable toward the proximal end from a locked position to a position following medicament injection. In the initial position, movement of the plunger holder is inhibited by interaction of a first biasable member with the plunger holder, the first biasable member recoiling when overlapped by an opening and/or recess of the sleeve such that the plunger holder is released.

Abstract: The present invention relates to a power unit for a medicament delivery device comprising a power body having opposite proximal and distal ends, a plunger rod driver coaxial and movably arranged in relation to said power body, a plunger rod coaxial and movably arranged in relation to said plunger rod driver, a force spring element operably connected between said plunger rod and said power body; wherein the plunger rod driver comprises first holding elements arranged to interact with second holding elements on said plunger rod and with the power body for releasibly holding said plunger rod with said force spring element in an injection tensioned state; third holding elements arranged to interact with fourth holding elements on said power body for releasibly holding said plunger rod driver in a penetration tensioned state; first attachment elements arranged to interact with second attachment elements on a medicament container holder, capable of attaching the two attachment elements together; and first blocking

Abstract: An injection device has a container holder in a medicament container housing; first and second energy accumulating members in the housing; a slidable sleeve; a plunger holder associated with the first energy accumulating member such that the plunger holder and container holder are axially movable toward a proximal end of the device from an initial position to a position following needle penetration; and a plunger rod operationally associated with the second energy accumulating member such that the plunger rod is axially movable toward the proximal end from a locked position to a position following medicament injection. In the initial position, movement of the plunger holder is inhibited by interaction of a first biasable member with the plunger holder, the first biasable member recoiling when overlapped by an opening and/or recess of the sleeve such that the plunger holder is released.
