摘要:
A cartridge with injection needles for an injection device. The cartridge includes a plurality of injection needle assemblies, each including a hub, mounted to be shiftable in cavities of a needle assembly support. A hub ledge having a drive member engageable push surface projects within a gap between a first hub portion and a second hub portion. Driving engagement of the push surface by an injection device drive member shifts the needle assembly from a retracted position to an injection position, during which shifting the second hub portion moves relative to the first hub portion. A pull surface on the second hub portion is engagable with the drive member for lifting the needle assembly from the injection position.
