Injection devices for delivering pharmaceutical compositions into the eye are described. Some devices include a resistance component for controllably deploying an injection needle through the eye wall. The resistance component may be disposed on the injector device, or on a portion of the injection device housing, or on a drug reservoir. Some devices may be removably attached to a drug reservoir, for example, through a luer connector. Other devices may comprise internal luer seal for securely connecting a drug conduit of the device to the luer cavity of a drug reservoir. Yet other devices may comprise a priming-enabling element to facilitate the drug priming of a shielded needle. Related methods and systems comprising the devices are also described.

A syringe (1) comprises a barrel (2), a stopper (3) and a plunger (4). The barrel (2) has a hollow interior, an orifice (21) and an opening (22) opposite to the orifice (21). The stopper (3) is arranged in the hollow interior of the barrel (2) thereby defining a sealed chamber (5) in the interior of the barrel (2). The stopper (3) is displaceable in the interior of the barrel (2) thereby varying a volume of the chamber (5). The plunger (4) extends through the opening (22) of the barrel (2) into the hollow interior of the barrel (2). The plunger (4) has a distal end (41) outside of the barrel (2) and a proximal end (42) inside the hollow interior of the barrel (2). The stopper (3) has a distal face (31) directed towards the plunger (4), a proximal face (32) directed towards the chamber (5) and an internal cavity (33) opening at the distal face (31). The syringe (1) is equipped with a sealing structure sealing the cavity (33) of the stopper (3) such that the cavity (33) of the stopper (3) is microbiologically sealed.

Logging device for drug delivery device

An add-on logging device (100, 300) mounted to a drug delivery device is turned on when the cap is removed. After a given amount of time in inactivity the sensor means of the add-on device is turned off automatically to save energy. If the user takes a dose of drug this is not detected as the add-on device is only turned on when the cap is removed. According to the present invention a warning message is provided when the cap is re-mounted after the sensor means has been turned off automatically, the warning message indicating to a user that an expelled dose may not have been detected.

Drug delivery device

A drug delivery device that includes a housing. The housing contains a syringe, and the syringe includes a container containing a liquid medicament. The container includes an aperture at a distal end and through which the liquid medicament can be dispensed. The syringe includes a stopper within the container. The stopper is moveable between a first longitudinal position and a second longitudinal position relative to the container, to cause dispensing of the liquid medicament through the aperture. The syringe includes at least one identifying means identifying the liquid medicament.

Holder with Safety Shield for a Drug Delivery Device
20180001035 · 2018-01-04 ·

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 springloaded 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.

Injection Device Having Variable Dosing

An injection device for injecting medicament in a patient comprises a housing configured to house a fluid reservoir that has one of a plurality of volumes of medicament. An injection conduit fluidly coupled to the fluid reservoir defines a fluid pathway from the fluid reservoir to the patient. A firing mechanism is coupled to the fluid reservoir and is configured to expel the medicament from the fluid reservoir through the injection conduit. A volume setting mechanism is coupled to the firing mechanism and is configured to select the one of the plurality of volumes of medicament for the firing mechanism to expel. A dose setting mechanism is configured to select all or a fraction of the one of the plurality of volumes of medicament that is injected from the injection conduit when the firing mechanism is actuated.
