Abstract
A fluid delivery device comprises a housing having a base including a bottom surface; a locking assembly including a cartridge receiver configured to receive a cartridge, the cartridge having a fluid reservoir and a septum configured to be generally perpendicular to the bottom surface when the cartridge is engaged with the cartridge receiver; and a needle assembly having a needle, the needle having a delivery end, a fluid coupling end, and a central portion located between the delivery end and the fluid coupling end, the needle assembly configured to move in laterally relative to the base to a first position and vertically relative to the base to a second position. The locking assembly prevents the needle assembly from moving to one or both of the first and second positions unless the cartridge is engaged with the cartridge receiver.
