  • Publication number: 20240066238
    Abstract: The present disclosure relates to a needle arrangement for a drug delivery device. The needle arrangement includes a distal needle tip and a proximal needle tip. The distal needle tip is held in a distal needle holder and wherein the proximal needle tip is held in a proximal needle holder. The distal needle tip and the proximal needle tip are in fluid communication with each other through a fluid channel. The fluid channel is adapted to allow axial movement of the distal needle tip and relative to the proximal needle tip between a compact state and an extended state. A length of the needle arrangement over the distal needle tip and the proximal needle tip in the extended state is greater than in the compact state.

  • Patent number: 11904151
    Abstract: The present disclosure relates to a cap for an injection device. The injection device comprises a body for holding a syringe having a needle extending from an end thereof. The cap is removably attachable to the body. The cap comprises an actuator and a needle shield to cover said needle. The cap further comprises a coupling between the actuator and the needle shield. The coupling is configured such that when the cap is attached to the body of the injection device axial movement of the actuator away from the body causes rotation of the needle shield relative to the body.
