A medicament delivery device includes a body having a proximal end and a distal end, in turn comprising a distal housing part, and a medicament container holder, adapted to receive a medicament container; a dose setting drum for setting a dose when rotated in a first direction and for delivering a dose when rotated in a second direction, and a drive drum sleeve selectively operably connectable to a piston plunger for delivering a dose.

Medicament delivery device

A dose setting mechanism for a medicament delivery device, which dose setting mechanism comprises, a tubular memberhaving a longitudinal trackof a predetermined length; a dose drum, coaxial with the tubular member, and being axially and rotationally movable relative to the tubular member; a stop member, axially movable but rotationally locked relative to the tubular member, and further being in an axially slaved connection with the dose drum; wherein said stop membercomprises a track followerin engagement with the longitudinal track, such that rotational movement of the dose drumrelative to the tubular membermay cause a maximum axial displacement of said dose drumand said stop member, relative to the tubular member, corresponding to said predetermined length.

Dose setting mechanism and medicament delivery device comprising ihe dose setting mechanism

The present invention relates to a medicament delivery device comprising a generally tubular distal housing part () having opposite proximal and distal ends, wherein third mechanically coded interface means () are arranged on its proximal end; a generally tubular proximal housing () part having opposite proximal and distal ends and being releasibly connected to said distal housing part, wherein with fourth mechanically coded interface means () are arranged on its distal end; a medicament container having a slidable stopper, wherein said container is arranged to be positioned within said proximal housing part; a plunger rod () arranged within said distal housing; drive means arranged within said distal housing and being operably connected to said plunger rod for driving said plunger rod and thereby said stopper towards the proximal end of the device; wherein said device further comprises an interface member () comprising first () and second () mechanically coded interface means arranged to match and interact with the third () and the fourth () mechanically coded interface means when the distal and the proximal housing parts are connected to each other.

According to aspects of the present disclosure, a retaining apparatus for use with a medicament delivery device is provided. The medicament delivery device includes a container holder assembly and an actuator assembly. The container holder assembly is configured to receive a container containing a medicament. The container holder assembly is configured to couple to the actuator assembly. The actuator assembly includes a plunger rod for engaging a stopper in the container. The retaining apparatus includes a plunger lock, a retaining member, and a biasing member. The plunger lock is seated within a proximal end of the actuator assembly, and secures the plunger rod. The retaining member is seated within the plunger lock. The biasing member is secured between the proximal end of the actuator assembly and the retaining member. The retaining member is biased in a proximal direction by the biasing member.

Container holder assembly

Container holder assembly for use in a medicament delivery device, comprising a tubular body elongated in an axial direction, said tubular body having a proximal end and an opposite distal end, and a retaining member releasably arranged to said tubular body for securing an elongated container placed inside the tubular body, wherein said retaining member comprises a resilient structure capable of exerting an axial force on said container in said tubular body for holding the container in a fixed position inside the tubular body and thereby avoiding displacement or breakage of the container and wherein a distal end of said container protrudes from a distal end of said tubular body.

A dose setting mechanism for a medicament delivery device, which dose setting mechanism comprises, a tubular member () having a longitudinal track () of a predetermined length; a dose drum (), coaxial with the tubular member (), and being axially and rotationally movable relative to the tubular member (); a stop member (), axially movable but rotationally locked relative to the tubular member (), and further being in an axially slaved connection with the dose drum (); wherein the stop member () comprises a track follower () in engagement with the longitudinal track (), such that rotational movement of the dose drum () relative to the tubular member () may cause a maximum axial displacement of the dose drum () and the stop member(), relative to the tubular member (), corresponding to said predetermined length.

Dose setting mechanism and medicament delivery device comprising the dose setting mechanism

A dose setting mechanism for a medicament delivery device is presented having a tubular member, a dose drum, coaxial with the tubular member, and being axially and rotationally movable relative to the tubular member, a stop member, coaxial with the tubular member, and axially movable but rotationally locked relative to the tubular member, and further being axially jointly movable with the dose drum, wherein the stop member has a first stop element and in that the dose drum has a second stop element, and wherein the first stop element and the second stop element are configured to interact with each other to limit rotation of the dose drum to a predetermined angular interval.

Container holder assembly for use in a medicament delivery device, comprising a tubular body elongated in an axial direction, said tubular body having a proximal end and an opposite distal end, and a retaining member releasably arranged to said tubular body for securing an elongated container placed inside the tubular body, wherein said retaining member comprises a resilient structure capable of exerting an axial force on said container in said tubular body for holding the container in a fixed position inside the tubular body and wherein the retaining member and the tubular body respectively comprises a first and a second locking means capable of achieving a mutual mechanical connection, such that the retaining member is locked to the tubular body.
