Abstract
Official abstract text for this publication.
The invention relates to a medical drug delivery apparatus which comprises a cartridge ( 1 ) being closed at one end by a membrane ( 12 ) and at the opposite end by a movable piston ( 15 ). A piston rod foot ( 1 ) is provided for transferring the pressure from the piston rod ( 20 ) of the drug delivery apparatus and onto the piston ( 15 ). The piston rod foot ( 1 ) comprises a center part ( 2 ) abutting the piston rod ( 20 ) and an outer part ( 3 ) which center part ( 2 ) and outer part ( 3 ) are releasable coupled together such that the two ( 2, 3 ) can be released when a force above a certain threshold limit is applied to the outer part ( 3 ).
First claim
