Further, a method is provided of retrofitting a standard aspirating syringe with the presently disclosed carpule retentive sleeve. Further, a method is provided of using the presently disclosed carpule retentive sleeve to retain a stopper inside the anesthetic carpule.

A medicament container holder for a medicament delivery device is presented having a C-shaped tubular body having a longitudinal gap extending along the entire axial extension of the C-shaped tubular body, which C-shaped tubular body is configured to be placed around a medicament container, wherein the C-shaped tubular body has a first axial end provided with an end flange extending radially inwards and configured to bear against a neck of a medicament container, and wherein the first axial end is provided with a lip extending proximally from the end flange.

An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder.

A drug delivery device for dispensing of a dose of a medicament includes an elongated body extending in an axial direction, a cartridge holder to accommodate a cartridge at least partially filled with the medicament and having an axially displaceable piston, and a piston rod to operably engage with the piston of the cartridge to displace the piston in axial distal direction. The drug delivery device further includes a coupling member connected with the cartridge holder and being axially displaceably arranged in the body for retracting the cartridge holder into the body during setting of a dose.

An autoinjector (100) for expelling a single dose of drug from a drug cartridge (600) including a piston (630), the autoinjector including: a base (200, 220), a needle (500) that is fixedly mounted relative to the base (200, 220), a plunger (310, 320, 400) adapted for cooperation with the piston (630), an actuating spring (330) provided as a helical compression spring arranged to act on the plunger (310, 320, 400) by exerting an axial force on the plunger to drive the piston (630) distally, and a needle shield (350, 380) axially movable relative to the base (200, 220) between an extended position and a collapsed position. The autoinjector defines a lock (320, 328, 380, 388) that is released when the needle shield (350, 380) is moved from the extended position to the collapsed position. The lock (320, 328, 380, 388) releases to enable relative rotation between plunger thread (325) and base thread (205) causing release of the plunger (310, 320, 400) from the initial axial position and expelling the dose of the drug.

A syringe system includes a syringe and a pressurization device for a syringe. The pressurization device for a syringe is configured so that the plunger advances by a forward rotation of the plunger, and the plunger retracts by a reverse rotation of the plunger. The plunger is advanceable by pressing the gasket at the time of the forward rotation and is retractable with respect to the barrel without pulling the gasket in the proximal end direction at the time of the reverse rotation.

The present invention relates in one aspect to a housing for an injection device, comprising: a body (30) to accommodate a drive mechanism (5) to operably engage with a piston (52) of a cartridge (50) filled with a liquid injectable medicament (53), a cartridge holder (20) having a cartridge receiving space (25) to accommodate the cartridge (50), wherein the cartridge holder (20) and the body (30) comprise an elongated shape and extend along an axial longitudinal direction (1, 2), wherein the cartridge holder (20) has an insert section (21) at a proximal end (23), wherein the body (30) has a receptacle (31) at a distal end (33) to receive the insert section (21) of the cartridge holder (20), wherein the body (30) comprises a first latch element (34) on an inside (32) of a sidewall (32) of the receptacle (31), wherein the cartridge holder (20) comprises a first through recess (24) in a sidewall (22) of the insert section (21) which through recess (24) is configured to receive the first latch element (34), wherein the through recess (24) comprises a narrowed neck receiving portion (24a) extending axially into a widened latch receiving portion (24b), wherein a first lateral width (w1) of the neck receiving portion (24a) is smaller than a second lateral width (w2) of the latch receiving portion (24b).

A drug delivery device for dispensing a drug from a reservoir includes a drive unit including an electronic control circuit and a coupling portion, and a reservoir unit including the reservoir with the drug and attachable to the coupling portion. The drive unit includes a plurality of switching elements operatively coupled to the control circuit, and the reservoir unit includes at least one actuation element adapted to selectively switch at least one switching element of the plurality of switching elements when the reservoir unit is attached to the drive unit. A control signal indicative of the reservoir or the drug is generated based on the switched switching element and sent to the control circuit.

An auto injector for delivery of a medicament is disclosed. The auto injector comprises a housing, a syringe holder configured to receive a syringe; a first drive module adapted to move the syringe holder relatively to the housing; and a rigid needle shield remover comprising a first part adapted for separating a rigid needle shield from the syringe.
