Medicament administration device has dosage adjuster mounted on piston rod and end stop mounted at end of its path, locking system preventing adjuster from rotating and pressing against stop

摘要

Medicament administration device has a dosage adjuster (9) mounted on the piston rod which is rotated to adjust the dose. An end stop (3c) is mounted at the end of its path and a locking system (8h, 9h) prevents the adjuster from rotating any further and pressing against the stop. An independent claim is included for a reservoir module for the administration device.
