An autoinjector includes a case adapted to hold a medicament container having a needle telescopically coupled to the case and movable between a first extended position relative to the case in which the needle is covered and a retracted position relative to the case in which the needle is exposed. The autoinjector includes a plunger rotationally and slidably disposed in the case rotatable relative to the case between a first rotational position in which the plunger is engaged to the case and a second rotational position in which the plunger disengages the case engages the plunger to rotate the plunger from the first rotational position to the second rotational position when the needle shroud translates from the first extended position to the retracted position. The autoinjector includes a cap removably coupled to the case includes at least one compliant case beam adapted to releasably engage at least one aperture in the case.

An injector (10) for injecting a medicament into a patient. The injector includes a container (18) defining a first chamber (22), which contains a fluid therein, and a second chamber (23). The injector also includes an injection conduit (126) configured for directing the fluid fired from the container into the patient. A transfer mechanism is operable by a user to transfer the fluid from the first chamber to the second chamber in a first stage of operation, and a firing mechanism is operable by the user for firing the fluid from the second chamber through the injection conduit in a second stage of operation. An energy source (62) is in powering association with the firing mechanism to drive firing mechanism in the first and second stages.

The disclosure relates to a drug delivery device including: a housing configured to contain a drug container with a needle, a needle shroud that is telescopically connected to the housing, and a cap that is configured to be releasably connected to the housing before use of the device. At least one of the cap and the needle shroud is adapted to unreleasably lock the cap onto the housing after reapplying the cap onto the housing after the drug delivery device is used.

Described is a cap for covering a needle shield on a needle of a medicament container, the cap comprising a cylindrical portion having a first outer diameter, a disc portion disposed on a distal end of the cylindrical portion, the disc portion having a second outer diameter larger than the first outer diameter, and a gripping surface disposed on an inner surface of the cylindrical portion and adapted to a frictionally engage a needle shield on a needle.

An apparatus includes a housing, a carrier, and an expandable assembly. The housing defines an opening configured to selectively place a gas chamber of the housing in fluid communication with an exterior volume. The carrier is movably disposed within the housing and is coupled to a medicament container. A proximal surface of the carrier defines a portion of a boundary of the gas chamber. The expandable assembly has a first member and a second member. The first member is coupled to an elastomeric member disposed within the medicament container, and the second member includes a valve portion. The expandable assembly transitions from a collapsed configuration to an expanded configuration when the elastomeric member moves within the medicament container. The valve portion moves relative to the opening when the expandable assembly transitions from the first to the second configuration, placing the gas chamber in fluid communication with the exterior volume.

A needle protection assembly, adapted to protect a tip of a hypodermic needle, comprising a shield adapted, in a protected operative orientation of the needle protection assembly, to shield the tip of the hypodermic needle, a locking element including at least one slot, the slot including at least three surfaces corresponding to three operative orientations of the shield, at least one slot engaging element, functionally associated with the shield, the slot engaging element being disposed within the slot of the locking element and movable relative thereto, between the surfaces, so as to transition the shield between the three operative orientations, and at least one biasing element, adapted for axial biasing of the shield, wherein the three operative orientations include a storage operative orientation, an injection operative orientation, and a needle protection operative orientation.

Described is a catheter patency maintenance device comprising of a flush syringe, an elongate plunger rod with a stopper slidably positioned within the barrel, a cap, disinfectant and a valve movable between an open position and a closed position. The valve may include a valve stem and/or openings in the valve to permit fluid flow. Methods of using the flush syringe assemblies are also described.

An automatic injection device, including a housing arranged along a longitudinal axis and having a forward end and a rearward end, the housing is configured to receive a syringe including at least one syringe piston and a needle coupled to a forward end thereof; a plunger rod adapted to be retained with respect to the housing in an initial operative orientation; at least one resilient element arranged to forwardly bias the plunger rod relative to the syringe; a needle shield adapted for selectable axial displacement with respect to the housing along the longitudinal axis, whereas rearward displacement of the needle shield exposes the needle and forward displacement of the needle shield covers the needle; and a trigger element configured to be axially rearwardly displaced upon rearward displacement of the needle shield relative to the housing and thereby allow forward displacement of the plunger rod relative to the syringe under the urge of the at least one resilient element.

The invention relates to an injection device (1) for injecting a pharmaceutical substance, having a proximal part (5) which has a drive (7) to implement an injection, and having a distal part (13) which is configured to accommodate an injection loading part (3), which has a packaging means receiving part (17) and a primary packaging means (23) which held in the packaging means receiving part (17) and in which a pharmaceutical substance is received, wherein the pharmaceutical substance can be injected from the injection loading part (3) when the injection loading part (3) is arranged in the distal part (13), wherein the distal part (13) is designed in such a way that the injection loading part (3) can be inserted axially into the distal part (13), and wherein the injection device (1) has a screen (15) which is designed and arranged in such a way that an injection needle (25) of the injection loading part (3) is concealed from a user during use of the injection device (1).

A part of a device for injecting a liquid product having an end sleeve and a syringe support which is able to move with respect to the end sleeve. The syringe support is designed to bear an injection syringe fitted with a removable protective cap. A deformable ring is kinematically connected to the syringe support. This ring can be deformed elastically between a configuration which is designed to axially immobilize the injection syringe in the syringe support, and a configuration designed to allow the protective cap to pass through the deformable ring.
