An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder.

An adapter assembly that includes a housing, a channel formed within the housing that is configured to receive a medical device, a first groove formed along an interior wall of the channel that is configured to at least partially receive a first retaining element, and a second groove formed along the interior wall of the channel that is configured to at least partially receive a second retaining element. The first retaining element is configured to extend outward from the first groove and the second retaining element is configured to extend outward from the second groove, such that the first and second retaining elements abut against the medical device received through the channel.

A device for injecting a medicament is provided. The device has a housing with a container within it which can hold a medicament. At its proximal end the container has a needle and a stopper. The device includes a plunger which at one end can engage the stopper. At the opposite end, the plunger can engage a first resilient member to move the stopper within the container to inject the medicament from the container. The device includes a collar with distal and proximal ends, the distal end engaging with a carriage and causing its rotation and the proximal end engaging with a second resilient member. The second resilient member can engage with a skin sensor which has distal and proximal ends. At the proximal end, the skin sensor can contact an injection site. The housing has a cap which can reduce or prevent movement of the skin sensor.

Described is a vial and syringe alignment guide that is designed to assist a user in filling a syringe from a vial. The guide includes both a vial attachment and syringe attachment. When a vial is affixed with the vial attachment, a syringe placed within the syringe attachment is aligned with the vial to allow the user to safely draw fluid from the vial.

A drug delivery device comprising a housing body; a piston rod configured to rotate in a rotational direction during dose dispensing under a driving force; and a threaded insert, wherein the piston rod is in threaded engagement with the threaded insert such that during the dose dispensing. the piston rod displaces axially in a distal direction relative to the threaded insert for displacement of a cartridge hung. The threaded insert is movable relative to a stop provided in the housing body and a spring is provided to bias the threaded insert against the stop so that the rotation of the piston rod causes the threaded insert to move away from the stop in response to reaction forces, induced by the cartridge bung into the threaded insert, acting on the piston rod in a proximal direction when the reaction forces exceed a biasing force of the spring.

A dose recording device (100) for a drug delivery device is disclosed, wherein the drug delivery device comprises a housing, a cartridge holder configured to receive a cartridge for holding a plurality of doses of a drug, and a dose setting member connected to the housing and configured to set the dose of the drug. The dose recording device (100) comprises a device housing (102), an electronic controller (114) disposed within the device housing (102), and at least one identifier member (120) configured to be mounted to the device housing (102). The electronic controller (114) comprises switches (116). The identifier member (120) comprises at least one actuation member (122) configured to actuate at least one of the switches (116) when mounted to the device housing (102). An actuation of the switch (116) is configured to provide additional information on the drug.

The present disclosure relates to a medicament container for accommodating a liquid medicament. The medicament container includes an elongated container barrel defining a longitudinal direction and having a proximal end and a distal end. The proximal end is opposite the distal end. The container barrel includes a proximal container cross section at the proximal end. The elongated container barrel includes a distal container cross section at the distal end and the proximal container cross section is substantially identical to the distal container cross section. The medicament container further includes a seal arranged at the distal end and extending across the distal container cross section, and a retainer engaged with the seal and engaged with the elongated container barrel to fix the seal to the distal end.

An injection device is disclosed wherein a dose can be set by rotating a dose setting member, whereby a push button is elevated from one end of the device a distance proportional to the set dose from a position fixed relative to the housing, and wherein the set dose can then be injected by pressing the push button back to its non-elevated position, through which motion a screw will move approximately the same distance or a smaller distance. The invention provides a method of reducing the dose force and/or the push-button movement during injection.

A device for performing injections in a patient includes a syringe holder with a needle guard, a cannula extending from the syringe holder, a needle slidably disposed over the cannula, and a slider on the syringe holder. The cannula has a blunt tip and a cannula length, and the needle has a sharp tip and a needle length that is shorter than the cannula length. The slider is coupled with the needle and is configured to slide the needle along the cannula from an extended position, in which the sharp tip of the needle is located at or immediately adjacent the blunt tip of the cannula, to a retracted position, in which the sharp tip is housed within the needle guard of the syringe holder.

A coded collapsible drug reservoir and a drug delivery system including the coded collapsible drug reservoir. The drug reservoir includes a collapsible housing and a port in communication with the collapsible housing. The drug reservoir further includes a coding feature disposed on the drug reservoir, and the coding feature identifies the drug reservoir.
