  • Patent number: 12329937
    Abstract: Auto-injector for administering a dose of a liquid medicament includes a housing to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament, the housing having a distal end and a proximal end with an orifice to apply against an injection site. A spring means, upon activation, can push the needle from inside the housing through the orifice and past the proximal end, operate the syringe to supply the dose of medicament, and retract the syringe with the needle after delivering the medicament. An activating means can lock the spring means in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring means for injection.

  • Patent number: 12318597
    Abstract: A syringe carrier includes a housing adapted to receive a syringe having a needle encapsulated by a removable protective needle sheath, and two or more flexible arms protruding inwards in a relaxed state and adapted to couple with the syringe in a mounted position. The flexible arms are adapted to deflect radially outwards in a pre-assembled position of the syringe in the syringe carrier. In the mounted position the flexible arms are allowed to return into the relaxed state due, in part, to an axial force operating on the syringe carrier. The disclosure further relates to an autoinjector and a method of assembling the autoinjector.

  • Patent number: 12318592
    Abstract: The disclosure relates to a drug delivery device comprising: a case adapted to hold a medicament container, a plunger disposed within the case and slidable from a proximal position into a distal position for delivering a medicament from the medicament container, at least one feedback mechanism that is in operative connection with the plunger, the feedback mechanism comprising a collar, a control spring biasing the collar in a distal direction, a needle shroud, operatively axially abutting the collar in a first coupled state and prevented from axially decoupling the collar by the plunger in its proximal position, wherein the plunger, when approaching the distal position during movement from the proximal position towards the distal position, is adapted to allow axial decoupling of the needle shroud from the collar, thus allowing for a limited axial movement of the collar relative to the needle shroud until the collar axially abuts the needle shroud in a second coupled state.

  • Patent number: 12318588
    Abstract: An assembly for a drug delivery device comprises a housing, a dose member which is displaceable in a proximal direction with respect to the housing for setting of a dose of a drug, a clutch member which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member configured to define a clutch stop position. The clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose.
