Abstract: A medicament delivery device comprises a housing, a needle, a needle cover, a needle cover biasing member, and a needle cover retaining mechanism. The needle cover is axially movable between an extended position and a retracted position. The needle cover biasing member is configured to bias the needle cover axially in a distal direction towards the extended position. The needle cover retaining mechanism is configured to be moved between a first state, in which the needle cover retaining mechanism is disengaged from the needle cover such that the needle cover is moveable in the distal direction under a force of the needle cover biasing member, and a second state, in which the needle cover retaining mechanism is configured to engage the needle cover and prevent distal movement of the needle cover under the force of the needle cover biasing member, when the needle cover is in the retracted position.

Abstract: A medicament delivery device has a needle for injecting medicament, a body and a needle cover. The needle cover is axially movable relative to a locked position in which the needle cover covers the distal end of the needle. The device has an inner housing with an aperture. A collar is located at least partially within the inner housing and is configured to rotate relative to the inner housing. The collar has one or more arms. A rotational member rotates the collar from a first position to a second position. When the needle cover is in the locked position and the collar is in the second position then the arm extends radially through the aperture and blocks proximal movement of the needle cover away from the locked position.

Abstract: The present disclosure relates to a medicament delivery device comprising a housing, a needle, a needle cover, a needle cover biasing member, a drive mechanism, and a needle cover extension mechanism. The needle cover is axially movable between an extended position and a retracted position. The needle cover biasing member is configured to bias the needle cover axially in the distal direction towards the extended position. The needle cover extension mechanism comprises a second biasing member and a release element. The second biasing member is configured to bias the needle cover into its extended position post-use of the device. The release element has a first state configured to prevent the second biasing member from biasing the needle cover into the extended position and a second state configured to allow the second biasing member to bias the needle cover into the extended position.

Abstract: The invention relates to a drug delivery device (1000) comprising a housing (100) configured to receive a medicament container (8) with a stopper (82) proximally sealing the medicament container. Furthermore, the drug delivery device comprises a plunger rod (1) arranged axially movable with respect to the housing and/or the medicament container and a feedback mechanism operatively coupled to the plunger rod. The drug delivery device has an initial state in which the plunger rod is in a start position. The drug delivery device is configured such that, in the initial state and when the medicament container is received in the housing, the plunger rod is axially spaced from the stopper. Furthermore, the drug delivery device is configured such that the plunger rod is axially movable from its start position in a distal direction into a feedback position.

Abstract: A drive subassembly for a drug delivery device includes a housing element, a drive member, an energy member configured to provide energy to induce a torque onto the drive member tending to rotate the drive member in a first rotational direction, wherein the drive subassembly has a first and a second locked state. In the first locked state, a first rotation-locking mechanism prevents a movement of the drive member in the first rotational direction induced by the energy member. In the second locked state, a second rotation-locking mechanism prevents a rotation of the drive member in the first rotational direction induced by the energy member and an axial-locking mechanism prevents an axial movement of the drive member. The drive subassembly is configured to be switched from the second locked state into the first locked state by releasing the axial-locking mechanism and moving the drive member in an axial direction.

Abstract: An arrangement for a drug delivery device includes a housing element, a plunger rod being arranged axially movable with respect to the housing element, a transfer member being arranged rotatably with respect to the housing element, an energy member configured to provide energy to induce a torque onto the transfer member, wherein the transfer member and the plunger rod are operatively coupled such that a rotation of the transfer member is converted into an axial movement of the plunger rod. The arrangement comprises a released state in which (i) the energy member induces a torque onto the transfer member, and (ii) the transfer member rotates in a first rotational direction due to the induced torque and thereby forces the plunger rod to move axially in a distal direction. The plunger rod being rotationally fixed with respect to the housing element.

Abstract: A drug delivery device includes a housing element, a release member, a plunger rod, a transfer member arranged rotatably with respect to the housing element, an energy member, a displaceable element being displaceable between a first position and a second position, wherein the transfer member and the plunger rod are operatively coupled such that a rotation of the transfer member is converted into an axial movement of the plunger rod, the drug delivery device has a first locked state, wherein, in the first locked state, (i) a releasable first locking mechanism prevents a rotational movement of the transfer member, (ii) the release member is in an initial position and arranged to hold the displaceable element in the first position, and (iii) the transfer member is coupled to the displaceable element held in the first position via an axial-lock interface which prevents an axial movement of the transfer member.

Abstract: A drug delivery device includes a housing element, a release member, a plunger rod, an energy member, and a displaceable element. The drug delivery device has a first locked state in which the release member is in a distal position and arranged to hold the displaceable element in a first radial position to prevent a movement of the plunger rod in distal direction by the energy member. The drug delivery device is configured to be switched from the first locked state into a released state by moving the release member from the distal position into a proximal position. In the released state, the release member no longer holds the displaceable element in the first radial position, which enables a movement of the displaceable element from the first radial position into a second radial position to release the plunger rod such that the plunger rod moves in the distal direction.

Abstract: A drug delivery device includes a housing element, a protection member, a movable member, wherein the drug delivery device has an initial state, in which (i) the protection member is in an extended position to cover the drug delivery element, (ii) the protection member is movable in a proximal direction from the extended position into a retracted position in order to expose the drug delivery element, and (iii) the protection member is coupled to the movable member in distal direction and proximal direction such that an axial movement of the protection member in both, the distal and proximal direction, results in an axial movement of the movable member in the same direction. The drug delivery device is configured such that, starting from the initial state, movement of the protection member in proximal direction initiates a rotation of the movable member relative to the protection member by a predetermined angle.
