A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip, a catheter hub (14) housing the catheter (22), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to cover at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).

An autoinjector (100′) for expelling a single dose of a drug from a held cartridge (600) comprising a piston (630). The autoinjector includes a needle shield (350, 380′) axially movable from an initial extended position via a triggering position to a trigger release position. The needle shield (350, 380′) is operatively coupled to a plunger release element (320′, 1320) cooperating with a plunger (310, 400) to define a releasable retaining mechanism that retains the plunger release element (320′, 1320) threadedly engaged with a base thread component (204′, 1204) in a predefined relative rotational and axial position and against rotational bias provided by an actuator (330). The needle shield (350, 380′) is configured for operating the retaining mechanism to release the retaining of the plunger release element (320′, 1320) and the base thread component (204′, 1204) from the predefined relative rotational and axial position upon the needle shield (350, 380′) being moved into the trigger release position.

The present disclosure relates to an injection needle assembly for use in a medicament delivery device. The injection needle assembly comprises an injection needle holder, an injection needle fixed to said injection needle holder, the injection needle having a proximal end and a distal end, and a sealing assembly for sealing the distal end of the injection needle. The sealing assembly comprises a spacer element surrounding the distal end of the injection needle and a sealing membrane for sealing the distal end of the injection needle.

A needle assembly including a needle having a sharpened end and an opposing end and a needle tip shield for shielding the needle. The needle tip shield includes a needle shield connectable to a base and a needle hub fixedly connected to the opposing end. The needle shield and needle hub displace relative to each other from a first state, in which the sharpened end of the needle is exposed outside the needle shield, to a second state, in which the sharpened end of the needle is shielded by the needle shield. An actuation button is movably connected to the needle hub to maintain the needle shield and needle hub in a releasable locked state in a first button position relative to the needle hub and to permit the needle shield and needle hub to displace relative to each other in a second button position relative to the needle hub.

A method of manufacturing one of a range of autoinjectors having cartridges (600, 600′, 600″) with different preset fill volumes, the method comprising the steps of: a) providing a front body assembly (100b, 100c, 100c′, 100c″), b) providing a cartridge (600, 600′, 600″) of given fill volume, c) providing a rear body assembly (100a) comprising a spring-driven drive ram assembly (310, 320) configured to drive the piston of a held cartridge (600, 600′, 600″), d) providing a ram spacer member (400, 400′, 400″), the ram spacer member defining a spacing geometry of length dimension (X1′, X1″, X1′″, XS′, XS″, XS′″, XR′, XR″, XR′″) selected according to the fill volume of the cartridge (600, 600′, 600″), and e) assembling a front body assembly (100b, 100c, 100c′, 100c″), the cartridge (600, 600′, 600″), the ram spacer member (400, 400′, 400″) and the rear body assembly (100a) so that the ram spacer member (400, 400′, 400″) is arranged axially between the drive ram assembly (310, 320) of the rear body assembly (100a) and the piston of a held cartridge (600, 600′, 600″).

The present invention relates to a medicament delivery device comprising a drive means configured to act on a medicament container for expelling a medicament; a holding means configured to hold said drive means in a pre-tensioned state; an activation means configured to interact with said holding means for releasing said drive means from the pre-tensioned state; wherein the device further comprises feedback means configured to interact both with said holding means and with said drive means for generating an audible and/or tactile and/or visual signal indicating that the medicament has been completely expelled.

Container holder assembly for a medicament delivery device comprising a housing part 22, a container holder 50, and a spring-biased needle guard 82, wherein the needle guard 82 is configured to disconnect from the container holder 50 upon movement from the extended position to the retracted position.

Devices, systems, and methods for performing injections with lowered likelihood of infection include catheters and other injection means with protective coverings. The protective covering can protect the catheter or other injection means before, during, or before and during insertion of the catheter into an insertion site. The protective covering includes two or more parts of interlocking protrusions and channels that allow for sliding motion of the parts relative each other but that resist separation of the parts in the direction perpendicular to the long axis of the two or more parts.

A holder with a safety shield for a drug delivery device; the shield obstructing access to a needle of the drug delivery device following use thereof. The safety shield may be actively deployed, in which case the health care worker must perform an action beyond complete depression of the pusher into the body of the drug delivery device to deploy the shield. Alternatively, the safety shield may be deployed passively or automatically, in which case deployment of the shield occurs upon complete depression of the pusher into the body, with no additional action required of the health care worker. The safety shield is spring-loaded and released to its extended position by a mechanical coupling of a series of position members, including levers, formed on the holder and the drug delivery device.
