A medicant injection device includes a compressible body, a tip, and an outer luer body. The compressible body has a proximal end, a distal end, and a plurality of bellows, and defines an inner cavity for holding a liquid medicant. The tip is positioned at the proximal end of the compressible body. The outer luer body includes internal threads, and is positioned over and engaged with the tip to form a first fitting therewith. The first fitting is configured to be connected with a second fitting. A medicant injection device includes a compressible body having first and second arms, a receptacle interconnected with the compressible body and defining an inner cavity, and a first fitting configured to engage a second fitting. The compressible body is configured to be compressed by forcing the distal end of the first and second arm toward each other.

The invention relates to a needle protection device for a pre-filled syringe with staked needle. This device comprises a blocking mechanism, comprising means for fastening to a syringe body, a needle shield, into which the needle can be driven, and an after-use safety system comprising a sleeve defining a central axis along which it is movable and means for resiliently loading the sleeve in a forward position in which it is able to cover the needle. The sleeve comprises an outer tube and a coaxial inner tube that are manufactured in one piece by injection molding, while the outer tube is arranged so as to cooperate with the blocking mechanism, and the inner tube is detachable from the outer tube and axially connected in translation with the needle shield.

An assembly includes a sealed drug reservoir unit, a subcutaneous flow conducting device in the form of a needle unit or an infusion set, and a flow communication unit. The flow communication unit includes a proximal hollow needle adapted to penetrate a needle-penetrable septum of the reservoir, a first flow-way inflow communication with the proximal needle and comprising a pressure-controlled valve, a second flow-way in flow communication with the first flow-way, an amount of preservative arranged to react with a substance received by the second flow-way, and distal flow communication structure adapted to provide flow communication between the second flow-way and the needle unit. The valve is controlled to open when the reservoir is pressurized, the preservative being provided to react with substances introduced to the second flow way via the needle unit.

An ophthalmic device including a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen is provided. The cannula is configured to deliver a fluid. A sleeve is disposed around the cannula and has a sleeve distal end. A handle is coupled to the sleeve and the cannula, the handle having an actuator. An internal mechanism is coupled to the actuator and is configured to pump the fluid. The internal mechanism includes an inlet port disposed on a handle proximal end, a drive member coupled to the actuator and a plunger coupled to the drive member. The ophthalmic device is configured to retain a volume of fluid and to be prevented from being re-primed after a predetermined number of actuator presses, wherein the retained volume of fluid is dispensed over an additional number of actuator pushes.

An assembly for a cartridge needle insertion mechanism includes a housing, a cartridge needle defining a cartridge needle axis and a cartridge closed by a septum. A cartridge needle slider is linearly guided by the housing along an insertion axis to be moved by a driver from a first position, where the cartridge needle is not penetrating the septum, to a second position where the cartridge needle penetrates the septum of the cartridge. A cartridge needle holder holding the cartridge needle is operatively coupled with the cartridge needle slider to be moved with the cartridge needle slider from the first to the second position. The assembly includes a compliant coupling between the cartridge needle holder and the cartridge needle slider configured to facilitate movement of the cartridge needle holder with respect to the slider when moved into the second position, thereby compensating for needle penetration forces.

A system for medicament delivery includes a cartridge containing a medicament and in fluid communication with a needle, where the needle is enveloped by a needle cap, a housing for containing the cartridge and having an orifice for allowing access to said needle cap and its associated needle, and a needle cap remover device.

A cap assembly for a drug delivery device is described comprising a cap, and a clip element which is configured to be attached to the cap, the clip element comprising a first component, and a second component, wherein the first component is at least partly received by the second component, wherein the first component and the second component are firmly connected to one another, and wherein the connection between the first component and the second component is the means by which the second component is attached to the cap. Moreover, a method for assembling a cap assembly is described.

A modular syringe assembly can include: a tubular syringe barrel having a proximal end and a distal end, the tubular syringe barrel defining a longitudinal axis; a plunger slidable within the tubular syringe barrel; and a cap assembly including a stopper portion and a Luer tip, the stopper portion receivable in the distal end of the tubular syringe barrel, the stopper portion defining a vent window. The cap assembly can be slidable within the tubular syringe barrel along the longitudinal axis between a sealed position where the vent window is covered by the tubular syringe barrel to prevent venting between the cap assembly and the tubular syringe barrel, and a vented position where the vent window forms a vent between the cap assembly and the tubular syringe barrel. Other features and methods are also described.

A syringe cap assembly includes a lock collar to be attached to an ejection port at a proximal end of the syringe, and a plastic cap screwed and thereby tightened into the lock collar. An external surface of the lock collar has projecting ribs that are each extended in an axial direction and are arranged in a circumferential direction to define recessed grooves, each recessed groove is extended in the axial direction and located between adjacent projecting ribs of the projecting ribs, and the adjacent projecting ribs are adjacent to each other in the circumferential direction. A bottom of an external surface of the plastic cap includes a protrusion extending in a direction toward the lock collar. At a stage where a tightening rotation of the plastic cap implemented by screwing the plastic cap into the lock collar is completed, the protrusion is located in the recessed groove between the adjacent projecting ribs.

The present disclosure describes a syringe assembly including a syringe including a Luer connection and a tip, a plunger, a tip cap, a tamper evident cap disposed over the tip cap, and a film including a frangible connection. The film secures the tamper evident cap to the Luer connection, where the frangible connection can break under a force applied to the tamper evident cap such that the tamper evident cap disengages from the Luer connection when the frangible connection breaks.
