Abstract: Described is a needle hub comprising a proximal end adapted to engage a medicament delivery device, a distal end having an opening, a shoulder disposed between the proximal end and the distal end, and a needle assembly engagement mechanism (F1) coupled to the shoulder and adapted to releasably engage a needle assembly. The needle assembly engagement mechanism (F1) includes two or more resilient arms adapted to releasably engage a retainer element on the needle assembly.

Abstract: Described is a needle assembly reuse prevention mechanism comprising a barrier movable between a retracted position and an extended position, a spring coupled to the barrier, a pin formed on the barrier, and a slot receiving the pin. When in the extended position, the barrier substantially covers an opening of a needle assembly storage compartment. The spring forces the barrier in a first direction. The slot has at least one abutment face for abutting the pin and preventing movement of the barrier in the first direction.

Abstract: The invention relates to a needle storage magazine for storing a number of injection needles and attaching and/or detaching them to or from an injection device, the needle storage magazine comprising a crescent shaped track having a convex part and a concave part, wherein the track is adapted to hold a set of needles in respective needle supports within the track, wherein the convex part is adapted to hold unused needles and used needles, wherein a centre position (B) is defined within the concave part for a needle in use or to be used, wherein a sliding carriage is arranged for attaching the injection device to the needle storage magazine such that the centre position (B) is essentially concentric to a longitudinal axis of the injection device, wherein a separation wheel is rotatably arranged, the separation wheel having at least one notch for entraining the needle support of one unused needle at a time from the convex part into the centre position (B) or the needle support of the needle in use out of the ce

Abstract: Described is a needle assembly storage device comprising a case having a first port and a second port, a first spool rotatably disposed in the case and adapted to support a storage unit of needle assemblies, a second spool rotatably disposed in the case and adapted to support the storage unit of the needle assemblies, and an actuator adapted to rotate the first spool or the second spool to advance the storage unit past the first port and the second port.

Abstract: Described is a needle assembly comprising a needle hub adapted to mount at least one medical needle. According to the invention, the needle hub is designed as a releasable clamping element which interchangeably holds the medical needle wherein the releasable clamping element is adapted to mount the medical needle in a non-positive locking manner and/or a positive locking manner in a holding position.

Abstract: A needle storage magazine for storing and dispensing a plurality of needle assemblies is presented, the needle storage magazine has: a plurality of mounting sleeves each adapted to mount an unused needle assembly or a used needle assembly, a case holding the mounting sleeves side by side, and a feeding and storage mechanism which feeds one of the unused needle assemblies within the mounting sleeve to an opening as well as which draws back one of the used needle assemblies into the mounting sleeve.

The needle assembly engagement mechanism (F1) includes two or more resilient arms adapted to releasably engage a retainer element on the needle assembly.

Abstract: Described is a needle assembly comprising of a needle and a hub coupled to the needle. The hub includes an engagement member adapted to engage an attachment arrangement on a medicament delivery device and a stop member adapted to abut the attachment arrangement to prevent proximal movement of the needle assembly.

Abstract: Described is a needle assembly storage system comprising a needle assembly including at least one hook formed on an outer surface, and a needle assembly storage device having at least one slot for receiving the at least one hook. The at least one slot includes a first recess formed in a wall of the storage device. The first recess includes a first abutment surface and a second abutment surface for preventing the at least one hook from moving out of the first recess.
