1. A system for injecting, comprising:
a cartridge body having proximal and distal openings, and a distal cartridge body interface;
a distal cartridge seal removably coupled to the distal cartridge body interface of the cartridge body, the distal cartridge seal defining
a longitudinal channel extending longitudinally through the distal cartridge seal, and
a sealing gland extending radially into the longitudinal channel:
a stopper member disposed in a cartridge interior of the cartridge body;
a plunger member having a plunger interior and configured to be manually manipulated to insert the stopper member relative to the cartridge body, the plunger member including
a needle retention feature disposed in the plunger interior,
an energy-storage member disposed in the plunger interior, and
an energy-storage member latching member disposed in the plunger interior; and
a needle hub assembly coupled to the distal cartridge body interface of the cartridge body, the needle hub assembly including
a needle having a needle proximal end feature,
a hub, and
a needle latching member configured to selectively prevent the needle from moving proximally relative to the hub,
wherein manipulating the plunger member relative to the cartridge body to transform the energy-storage member latching member from a latched state to an unlatched state retracts the needle proximal end feature proximally through the stopper member.
