A safety needle device includes a housing including a passageway with a needle cannula extending therefrom. A shielding member is movable between a first position in which a puncture tip of the needle cannula is exposed therefrom and a second position in which the puncture tip of the needle cannula is encompassed therein. The shielding member is maintained in the first position against a biasing force which biases the shielding member toward the second position. A fluid and/or a temperature activation material is associated with the shielding member and is adapted to deform upon contact with a fluid medium and/or a certain temperature or temperature range. The fluid medium flowing through the needle cannula causes the fluid activation material to deform, such as through expansion, thereby releasing the shielding member from the first position and allowing a drive member to bias the shielding member toward the second position.

A grip accessory for a manual injection device comprises a housing having a generally hollow body for supporting a manual injection device therein. The housing comprises a distal portion comprising a first opening into which a manual injection device can be inserted, a proximal portion comprising a second opening through which a needle of the manual injection device is extendable, the proximal portion comprising a skin contacting surface at a proximal end of the device. An intermediate portion extends between the proximal and distal portions and guide means is provided on an interior surface of the distal portion for guiding a plunger rod of an injection device during delivery of an injection.

In some embodiments a system and method are described for safeguarding a hazard, the hazard, for example a needle point, may be moved between a protected retracted position, an active extended position and/or an intermediate position. Optionally in the retracted position, the hazard may be protected inside a housing. Optionally in the extended position, the hazard may be exposed. Optionally, in the intermediate position the hazard may be partially protected and/or concealed, for example by a shield and/or in an indentation. In some embodiments, compromising a shield causes the hazard to be retracted to the retracted position.

The invention relates to an injection device for injecting doses of a liquid drug, which comprises an immobilization mechanism such that the further use of the injection device is immobilized in response to the needle cannula (20) being exposed to an axial force above a predetermined value: the immobilization mechanism comprises a flexible arm (50) which apply a radial force onto the needle cannula at least during injection.

A packaging for storing a drug delivery device comprising a container provided at its distal end with a distal tip bearing a needle, the needle being covered by a shield, the packaging comprising: a support comprising: a first holding element configured for receiving at least part of the shield before use, a second holding element configured for receiving a distal part of the needle after use, and an envelope for receiving the drug delivery device, the envelope being closed by the support.

An injection pen comprises a starting mechanism (1) and a driving mechanism (2). A needle pin (40) of the starting mechanism (1) fitted to a connecting rod (30) and a front spring (60) is disposed in a front housing (10) and an inner casing (20) therein. A front cover (50) is disposed at the front end of the front housing (10) and covers the needle pin (40). A rear housing (70) of the driving mechanism (2) and a driving casing (80) therein are connected to the front housing (10). A trigger tube (90) and a key panel (A0) are mounted in the driving casing (80). A push rod (A1) fitted to a rear spring (A2) is mounted in the trigger tube (90). An elastic baffle (83) of the driving casing (80) fastens the driving casing (80) and the push Rod (A1) and locks the rear spring (A2). An injection needle group (3) can be mounted between the starting mechanism (1) and the driving mechanism (2). When the front cover (50) is removed, the needle pin (40) can be pressed and inwards retreated into the front housing (10) to make a needle (3A) to be exposed, and the inwards retreated needle pin (40) drives the connecting rod (30) to push away the elastic baffle (83) of the driving casing (80) to perform unlocking. The released rear spring (A2) pushes the push rod (A1) to make an injection needle group (3) to transfer a drug. After the injection, the needle pin (40) is reset under the push of the front spring (60), and the needle pin (40) is fastened in the inner casing (20) when a key panel (A0) is pulled out by means of the connecting rod (30), so that the needle pin (40) cannot be pressed to inwards retreat, and accordingly, a used syringe needle (3A) is protected, so as to prevent users from being hurt by the needle by accident.

Modular fluid path assemblies are provided that include conduit, coupling, and needle portions of a fluid path fluidly coupled to an outlet of a container. The modular fluid path assemblies further include a needle shield having a tip of the needle embedded therein. So configured, in embodiments, the modular fluid path assemblies can be sterilized, a medicament can be filled in the container, and a stopper inserted in the container so that the pre-sterilized and pre-filled modular fluid path assemblies can have a closed container integrity (CCI) seal.

A distribution assembly having a syringe having a body with a tip supporting a needle having a bevel, and a removable syringe needle protection device. The protection device has a flexible cap defining an inside cavity defined by a side wall and by a distal solid end wall, and when in the protection position, receiving the bevel of the needle in airtight manner. The side wall includes an annular bead provided with at least one slot extending across the bead in a longitudinal direction, the bead, when in the protection position, co-operating in airtight manner with the tip of the syringe. The cavity of the cap is dimensioned so that when the protection device is removed from the syringe, the cavity is connected to the atmosphere via the slot before the bevel of the needle becomes connected to the cavity.

The present invention relates to a needle shield assembly for a syringe (10), comprising an inner needle shield (16) which is flexible and designed to enclose a major part of a hollow injection needle (18) of said syringe; an outer needle shield (20) which is rigid and designed to enclose a major part of said inner needle shield (16), which outer needle shield (20) is arranged with a number of passages (22) for allowing sterilizing agents to reach said injection needle (18) during a sterilization process. The invention is characterised in that said needle shield assembly further comprises a cover element (24; 36; 46) arranged adjacent said passages (22) such as to prevent the interior of said injection needle (18) from being exposed to oxygen via said passages (22) of said outer needle shield (20) after said sterilization process.

An automatic injection device configured for injection of a material stored in a syringe into an injection site, the syringe including a generally cylindrical storage container and a piston disposed therewithin, whose exact initial axial position within the container is not predetermined, wherein axial forward displacement of the piston in the container forces the material forwardly out of the container, the automatic injection device including at least one spring drive assembly operative, when actuated, to initially apply a first axial force to the syringe, thereby to axially displace the syringe in a forward direction, and thereafter, responsive to driving engagement with the piston, to apply a second axial force, substantially greater than the first axial force, notwithstanding the fact that the exact axial position of the piston within the container is not predetermined, to the piston, thereby to axially forwardly displace the piston relative to the syringe.
