Medicament Delivery Device
摘要:
A medicament delivery device has proximal and distal housing parts connected along a longitudinal axis, the proximal part for accommodating a medicament container. A drive member inside the distal part has a first circumferential set of interacting devices. A longitudinal plunger rod is rotationally locked through a central passage of the distal part, acts on a stopper inside the container, and is connected to the plunger rod. A turnable dose setting member coaxially arranged around the drive member is rotatably connected to the distal part. A torsion spring is connected to the dose setting member and to a hub of the drive member. The hub, spring, dose setting member, and drive member are coaxial transversally. The drive nut has second interacting devices on its outer surface. When the drive member is rotated by the spring, the drive nut rotates, whereby the plunger rod moves proximally for expelling a dose of medicament.
