An injection device, for example, an auto-injector of any type, includes a sleeve configured to hold a medicament chamber. The sleeve may be sufficiently deformable such that it functions as a shock absorbing member to distribute the force exerted on the medicament chamber during use of the injection device.

Container holder assembly for use in a medicament delivery device, comprising a tubular body elongated in an axial direction, said tubular body having a proximal end and an opposite distal end, and a retaining member releasably arranged to said tubular body for securing an elongated container placed inside the tubular body, wherein said retaining member comprises a resilient structure capable of exerting an axial force on said container in said tubular body for holding the container in a fixed position inside the tubular body and thereby avoiding displacement or breakage of the container and wherein a distal end of said container protrudes from a distal end of said tubular body.

A medicament container holder for securing a medicament container having a generally tubular body arranged with a proximally directed neck portion and a flange portion arranged with a pierceable septum. The medicament container holder has mechanical holding elements that interact with the flange portion for preventing movement of the medicament container in a distal direction and having mechanical fixation elements configured to interact with the flange portion for urging the flange portion in the distal direction against the holding elements, where the medicament container holder has attachment elements for a medicament delivery member. The mechanical fixation elements are configured to engage with the medicament delivery member when attached to the attachment elements, such as to exert a force in the distal direction on said flange portion.

An auto-injector for receiving and operating a syringe. The auto-injector includes a housing for receiving the syringe, the housing comprising a main body and a hinged door operable into an open position and a closed position. The syringe is receivable within the housing when the hinged door is in the open position. At least one charging link is connected between the main body and the hinged door, wherein a connection of the at least one charging link to the main body and/or a connection of the at least one charging link to the hinged door is a slidable connection configured to slide on opening and closing of the hinged door and configured to couple to at least one drive spring for priming of the at least one drive spring on the opening of the hinged door and/or the closing of the hinged door. The at least one drive spring is configured on activation of the auto-injector to drive a plunger driver forward within the auto-injector to operate the syringe received within the auto-injector.

Provided is a cassette unit suitable for use with an auto-injector having a drive unit. The cassette unit comprises a cassette unit housing defining a cassette unit housing cavity, which is in receipt of a syringe, a rearward entrance to said cavity and a forward needle projection aperture. The cassette unit also comprises in capping relationship with the rearward entrance of the cassette unit housing, a cassette unit end-cap, said cassette unit end-cap defining a drive rod-receiving opening for receipt of a drive rod for providing forward axial drive to said plunger; a biasing element defining a biasing relationship between the cassette unit end-cap and an end flange of the syringe barrel, thereby urging the syringe forwards in relation to the cassette unit end-cap; and a damping element defining a damping relationship between the cassette unit end-cap and the flange of the syringe, thereby acting to damp rearward movement of the syringe relative to the cassette unit end-cap.

An injector including a syringe arranged along a longitudinal axis, a removable cover for removable engagement with the syringe and a cover removal assembly including an outer portion which is engagable by a user and is movable axially in a cover disengagement direction along an axial travel path with respect to the longitudinal axis and an inner portion which includes at least one engagement portion which is engagable with the removable cover, whereby axial movement of the inner portion in the cover disengagement direction removes the removable cover from the syringe, at least one of the outer portion and the inner portion being configured such as to provide an axially floating lost motion engagement between the outer portion and the inner portion.

Implementations relate to an electronic add-on module releasably attachable to an injection device prior to injection, a sensor element for detecting a state or process in the injection device, a processor element for evaluating and/or processing a signal of the sensor element, and an energy store for supplying the processor element with energy. The add-on module has a first module part, which is connectable along its longitudinal axis to the injection device in an axially fixed manner by means of a holding mechanism. A second module part is movable for a damped relative movement, such as a deceleration or braking movement, by a delay stoke with respect to the first module part connected to the injection device. By damping a relative movement between two module parts, the force transmission between the add-on module and the injection device is controlled and a maximum force surge is limited to the injection device.

The present invention relates to a medicament container holder (10) comprising a body (12) adapted to receive a medicament container (14), the body (12) comprising proximally directed tongues (38) at its proximal end, engagement elements (42) arranged at the proximal end of the tongues (38), directed inwards, which engagement elements (42) are arranged to engage a neck portion (46) of the medicament container (14); wherein the tongues (38) deflect radially outwards when engaged by a needle shield (16) of said medicament container (14). The invention is characterized in that said tongues (38) with said engagement elements (42), engage with said neck portion (46) of said medicament container (14) for preventing the medicament container (14) from moving in a proximal direction relative the medicament container holder (10), when disengaged with said needle shield, wherein said tongues (38) are in a stressed state when in engagement with said neck portion (46).

The present disclosure refers to a housing element for a drug delivery device. The housing element comprises longitudinal axis and defines an interior space for receiving components of a drive mechanism of the drug delivery device and at least a portion of a cartridge of the drug delivery device. The housing element comprises an engagement feature for axially constraining the housing element to a cartridge holder of the drug delivery device. In order to constrain the cartridge in the housing element, it further comprises at least one crush web protruding radially inwards into the interior space. The at least one crush web is angled relative to the longitudinal axis of the housing element by at least 3 such that when the cartridge is introduced into the interior space the at least one crush web folds radially outwards.

The present invention relates to a medicament container holder (10) comprising a body (12) adapted to receive a medicament container (14), the body (12) comprising proximally directed tongues (38) at its proximal end, engagement elements (42) arranged at the proximal end of the tongues (38), directed inwards, which engagement elements (42) are arranged to engage a neck portion (46) of the medicament container (14); wherein the tongues (38) deflect radially outwards when engaged by a needle shield (16) of said medicament container (14). The invention is characterized in that said tongues (38) with said engagement elements (42), engage with said neck portion (46) of said medicament container (14) for preventing the medicament container (14) from moving in a proximal direction relative the medicament container holder (10), when disengaged with said needle shield, wherein said tongues (38) are in a stressed state when in engagement with said neck portion (46).
