An antiseptic medical cap that may include a base, a sidewall, and a chamber configured to receive a proximal end of a medical fluid port having an opening. The antiseptic medical cap, in some instances, may include an insert having a gas-releasing anti-microbial compound and/or include a nitric oxide-releasing system that is configured to be positioned at least partially through the opening of the medical fluid port when the antiseptic medical cap receives the proximal end of the medical fluid port into the chamber.

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen.

A locking mechanism is provided for use with a reservoir and a reservoir holder so as to prevent unwanted tampering with the reservoir. The mechanism comprises a main body with an aperture that is coupled to the reservoir. A hinged flange is provided on the main body. The flange folds inwards at the pivot point provided by the hinge, toward the aperture of the main body, allowing the mechanism to pass over the ferrule of the reservoir. Once the mechanism is placed over the cartridge, the flange folds toward the reservoir at the pivot point, flexing away from the main body. The flange rests against the underside of the reservoir ferrule, thereby retaining the reservoir within the locking mechanism. The locking mechanism may be for use with either a disposable or a reusable delivery device.

A syringe for use with a medical injector system includes a barrel and a semi-rigid hub, the hub having an outer surface adapted to slidingly move within the barrel, and an inner surface having a continous circumferential wall. The hub further includes an annular engaging portion recessed within at least part of the continous circumferential wall forming a groove, at least one radially extendable and retractable retention member disposed at partially within a proximal cylindrical portion of the hub, and the elastometric seal engaged with a seal engaging portion on the hub and slidingly engaged with the barrel of the syringe. The semi-rigid hub and the elastomeric seal are reciprocally slidable within the barrel, and the at least one radially entendable and retractable retention member is configured to releasably engage the groove upon retraction of the plunger to permit the semi-rigid hub to be selectively withdrawn within the barrel.

An automatic needle device comprises a body into which a needle assembly and needle are mounted. The device also includes a needle guard to cover the needle until it is used and to lock over the needle after use so the needle is not re-exposed. The locking is accomplished with a coil spring action locking device. A container for holding the automatic needle device also facilitates the viewing of the distal end of the needle prior to use on a patient.

A needle actuator assembly for a drug delivery system includes a needle actuator body having a guide surface, a needle shuttle having a cam surface, with the needle shuttle moveable along a vertical axis between a first position and a second position. The needle shuttle is configured to move between the first and second position through engagement between the guide surface of the needle actuator body and the cam surface of the needle shuttle. The assembly further including a needle received by the needle shuttle.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.

A cap assembly for a medicament delivery device having a housing and a medicament container holder. The cap assembly includes a retainer member connectable to the container holder; a hub having a needle and coaxially movable within the retainer member; an inner cap connected to the hub and the retainer member; an outer cap coaxially arranged to the inner cap; and a cap clutch mechanism having a locking member that is axially movable in relation to the inner and outer caps between a disengaged position, in which the outer cap is rotatable relative to the inner cap, and an engaged position, in which the outer cap is rotationally locked to the inner cap. The cap clutch mechanism also has a clutch biasing device arranged between the outer cap and the locking member for biasing the locking member for keeping it in the disengaged position.

Embodiments of a retractable syringe assembly are provided that include a dual syringe barrel configuration. One or more embodiments include reuse prevention features and features that prevent premature activation of the retraction mechanism. Methods for aspirating and expelling liquid from medical devices are also provided.

A connecting module is provided with a first connecting component, which has a first fluid channel and a first contact surface, a second connecting component, which has a second fluid channel and a second contact surface. One of the two contact surfaces is formed as an inner surface and the other of the two contact surfaces is formed as an outer surface which is complementary to the inner surface. The connecting module further includes a receiving sleeve with a first threaded section and a first connecting device for the first connecting component. The first connecting component has a second connecting device, which interacts with the first connecting device in such a way that the first connecting component is detachably connected to the receiving sleeve. The second connecting component has a second threaded section which is complementary to the first threaded section.
