The invention relates to an automatic drug delivery device (10), in particular automatic dmg delivery device, for dispensing a fluid product, in particular a fluid medicament, including: a longitudinal housing (104) extending along a longitudinal axis and having a proximal end close to the dispensing site, a distal end opposite to the proximal end and a hollow interior; a removable cap (50) mountable to the proximal end of the housing (104); a syringe assembly (200) arranged a mounting position inside the housing (104) and having a hollow syringe body (204) and an injection needle (206) coupled to the hollow syringe body (204) including the fluid product; a drive mechanism (300) which can be triggered by a trigger element in order to initiate the dispensing of the fluid product; wherein the loaded drive mechanism is operatively coupled with a safety shield (102) movable within the longitudinal housing (104), wherein the safety shield (102) is biased into a proximal position in which it protrudes out of the proximal end of the longitudinal housing (104) in order to cover a needle tip (348) of the injection needle (206), and wherein the safety shield (104) is movable into a distal position in which the injection needle (206) is exposed for injection; the device further including a feedback mechanism providing a visual feedback to the user indicating an actual state of operation, wherein the feedback mechanism includes a visual indicator which appears in a transparent window on the distal end of the housing.

An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as said drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.

A medication injection pen comprises a dose set knob rotatable with respect to a housing to set a desired injection dose. The dose set knob comprises at least one internal thread. A leadscrew includes a thread element for advancing in a first direction via a corresponding thread engagement. A driver is rotationally fixed to the leadscrew and is rotatable in a first direction to rotate and advance the leadscrew in the first direction. The setback member is rotationally fixed to the driver. The dose stop member is rotationally coupled to the setback member and is axially movable relative to the dose set knob when the dose set knob is rotated relative to the setback member. Axial movement of the dose stop member limits the user from setting a dose that is greater than an injectable volume of medication remaining in a cartridge.

A user-powered medicament injector including a reusable, user-powered automatic injection assembly including a user energizable medicament injection subassembly and a medicament module removably insertable into the reusable, user-powered automatic injection assembly and including a module housing adapted to receive a syringe having a barrel, a needle engaged to said barrel, and a removable needle cap covering the needle; a needle shield configured to be moveable with respect to the module housing and a needle cap remover associated with the needle shield. The medicament module is configured for energizing the user energizable medicament injection subassembly by insertion of the medicament module into the reusable, user powered automatic injection assembly.

The present disclosure relates to a cartridge holder of an injection device, the cartridge holder comprising a tubular shaped elongated sleeve extending in an axial direction to accommodate a cartridge filled with a medicament, wherein the sleeve (29) comprises: a proximal connecting end to connect with a distal connecting end of a body of the injection device, which body is configured to accommodate a drive mechanism of the injection device and which drive mechanism is operably engageable with a piston of the cartridge, a flange section extending radially outwardly from an outside surface of the sleeve and having a proximally facing abutment face to axially abut with a distal end face of the distal connecting end of the body, at least three protrusions located distally from the flange section, extending radially outwardly from the outside surface of the sleeve and being distributed around the circumference of the sleeve.

An injection device adapted for injecting a durable or pre-filled pen device along an injection direction defining an injection axis. The injection device is provided with a certain holder and locking mechanism for fixing and holding a pen device in a correct position for injection into human skin.

An automatic medicament delivery device for auto injections that has a re-usable part containing a driving and a signal mechanism and a disposable part containing a syringe or a cartridge with a medicament. The parts can be interconnected simply in one axial move avoiding any rotation or turning. The device is easily and safely connected from two parts prior and during the injection process and automatically dissembled when the injection is completed allowing to remove the disposable part.

A drug injection system includes a cartridge adapter and a drug injection device. The cartridge adapter includes: a main body case; an attachment portion provided on the main body case used for attachment to the drug injection device; an accommodating portion that accommodates therein a drug cartridge; a piston; a piston gear that allows the piston to slide therethrough; a stopper that stops movement of the piston gear; and a release lever that releases a locked state of the piston gear. The drug injection device includes: a casing that accommodates therein a portion of the cartridge adapter; an engagement portion that engages with the cartridge adapter; a drive gear to which the piston gear of the cartridge adapter is connected; a motor connected to the drive gear; and a release bar that drives the release lever of the cartridge adapter.

A stopper for use in a cartridge or syringe of a medical device .sub.[SL6]is configured to be disposed within a container closure system. The stopper comprises a shell comprising a closed end and an open end with sidewalls extending between the closed end and the open end along a longitudinal axis of the shell. The open end defines a cavity and the sidewalls define an exterior surface sized and shaped to fit inside the container closure system. An insert is configured to be inserted into the cavity, receive a force from a plunger rod, and distribute the force to the shell in order to advance the shell into the container closure system. The closed end of the shell in the cavity defining a convex surface configured to be contacted and deflected by the insert upon insertion into the cavity includes an elastic and/or plastic deformable material.

A system includes: a body including an internal cavity and an internal reservoir; a holder configured to hold an ampule and configured to be slidably received in the cavity; and a clip configured to connect to the holder, wherein the holder is configured to slide into the cavity to a first position when the clip is operatively connected to the holder, and wherein the holder is configured to slide into the cavity to a second position when the clip is not connected to the holder. A method includes manufacturing the system. Another method includes administering an injection using the system.
