EP4469110A1 — Sub-assembly for a medicament delivery device

USPTO Abstract

A sub-assembly for a medicament delivery device, the sub-assembly comprising: a sub-assembly housing extending along a longitudinal axis between a distal end and a proximal end, wherein the sub-assembly housing comprises a flexible arm extending in a distal direction of the sub-assembly housing, and wherein the flexible arm comprises a distally directed flexible arm surface, a rotator comprising a support wall extending in the direction of the longitudinal axis, a plunger rod comprising a proximally directed plunger rod surface adjacent to the distally directed flexible arm surface, a biasing member extending in the direction of the longitudinal axis between a proximally directed sub-assembly housing surface of the sub-assembly housing and a distally directed surface of the plunger rod, and wherein the rotator is rotatable around the longitudinal axis relative to the sub-assembly housing from a first rotator position where the support wall is adjacent to an outer surface of the flexible arm of the sub-assembly housing to a second rotator position where the support wall is circumferentially offset to the outer surface of the flexible arm.
