The present disclosure relates to medicament injection devices. An injection device includes: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity, a sensor arrangement including a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency, a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency, and a processor arrangement configured to, based on the detected movement, determine a medicament dosage administered by the injection device.

Medicament injection device

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.

Needle actuator assembly for drug delivery system

Data collection devices for attachment to injection devices are disclosed. In one embodiment, the data collection device includes: a body attachable to a dial member of the injection device, a sensor arrangement comprising a sensor and a scale, and a processor. The sensor is configured to detect a rotation of the body relative to a trigger of the injection device. The processor is configured to detect a rotation of the body relative to the trigger. One of the sensor and the scale is arranged in or on the body and wherein the other one of the sensor and the scale is located on the trigger or is rotationally lockable to the trigger configured to detect a rotation of the body relative to the trigger.

Data collection device for attachment to an injection device

A drive assembly for a drug delivery system including a plunger member configured to engage and move a stopper within a container, a biasing member configured to move the plunger member, and an adjustable spacer assembly positioned between the plunger member and the stopper. The spacer assembly includes a spacer element attached to the stopper and at least one shim or includes a spacer element and a holder to which the spacer element is attached. The holder may be attached to the stopper and the spacer element may be attached to the holder by a threaded engagement. Also, a drug delivery system for injecting a medicament, the system including a container configured to receive a medicament, the container comprising a stopper configured to move within the container and a closure, a drive assembly as described above, and a needle actuator assembly.

Spacer assembly for drug delivery device

The disclosure relates to an injection device for setting and injecting pre-set or user-selectable doses of a medicament, the injection device comprising an elongated housing defining a longitudinal direction and configured to accommodate a cartridge containing the medicament, and a detector arrangement operable to detect a relative movement between a first element and a second element. The first element is subject to a first movement relative to the second element along a first longitudinal direction for setting of a dose, the first element is subject to a second movement relative to the second element along a second longitudinal direction for dispensing of the dose, one of the first movement and the second movement is a helical movement, and the other one of the first movement and the second movement is a sliding movement in the longitudinal direction. The second element comprises at least one reference element fixed to the second element.

Injection device and detector arrangement

A needle actuator assembly for a drug delivery system includes a housing, a needle having retracted and extended positions, a needle actuator body received within the housing and configured to move from a pre-use position where the needle is in the retracted position to a use position where the needle is in the extended position and to a post-use position where the needle is in the retracted position, with the needle actuator having a button contact surface, and an actuator button received by the housing.

Actuator assembly for drug delivery system

A drug delivery system for injecting a medicament includes a housing, a container configured to receive a medicament including a stopper configured to move within the container and a closure, a needle in fluid communication with the container, a spacer configured to be engaged with the stopper, a first plunger, a first spring configured to bias the first plunger in an axial direction, second plunger disposed about the first plunger, a second spring configured to bias the second plunger in an axial direction. The first plunger is configured to move the spacer and the container relative to the housing via the first spring to establish fluid communication between the container and the patient needle, and the second plunger is configured to move the spacer and the stopper relative to the container via the second spring.

Drive assembly and spacer for drug delivery system

A drug delivery system for injecting a medicament is provided. The system includes a container configured to receive a medicament; a drive assembly which, upon actuation, is configured to expel the medicament from the container; a needle for injecting the medicament to a patient; a fluid path assembly comprising a tube in fluid communication with the container and the needle for conducting fluid from the container to the needle; and a tube crimping arrangement configured to engage the tube to block fluid flow through the tube. The drive assembly causes the tube crimping arrangement to engage the tube after a dose of the medicament has been delivered to the patient through the needle.

Tube crimping arrangement for drug delivery device

Medicament injection device with rotary encoder

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.
