Patent ID: 11285264

Abstract:
A mix and triggering assembly for a medicament delivery device, comprising: a housing structure having a proximal end and a distal end, a delivery member cover, a rotator sleeve, and a triggering member configured to be rotatably locked with the rotator sleeve and the delivery member cover, the triggering member being configured to move axially relative to the rotator sleeve, wherein the delivery member cover, the rotator sleeve and the triggering member are configured to be received by the housing structure, the delivery member cover being configured to extend from the proximal end of the housing structure, wherein the delivery member cover, the rotator sleeve and the triggering member are rotatably arranged relative to the housing structure, wherein the housing structure has a thread structure and the rotator sleeve and the triggering member are configured to be in a threaded connection with the thread structure in a ready to mix position of the triggering member, preventing irrotational axial movement of the triggering member relative to the housing structure towards the distal end of the housing structure, wherein rotation of the delivery member cover relative to the housing structure causes the rotator sleeve and the triggering member to be screwed from the ready to mix position towards the distal end of the housing structure until the triggering member reaches a dose setting position, in which the triggering member is configured to be released from engagement with the thread structure, enabling irrotational axial movement of the triggering member further towards the distal end of the housing structure.
