Abstract
The present invention relates to injection devices for injecting a medicament from a cartridge () through a needle cannula (). The injection device () includes an actuator () for driving a piston driver () and includes an end of stroke limiter (). When the piston driver () is arrested by the end of stroke limiter () a shielding driver () is automatically triggered to actively shift the needle cannula () into a shielded state. The injection device may include a fluid dispensing interruption mechanism that automatically interrupts fluid flow when the piston driver has moved a predetermined stroke length. The injection device may also include a single pre-stressed spring acting exclusively in a linear compression mode or exclusively in a torsion mode and adapted to sequentially drive the device to enable fully automatic operation. The invention also relates to a method of sterilizing a needle cannula assembly.
