Abstract
A system for serially injecting liquids includes a syringe body, proximal and distal stopper members disposed in the syringe body, a first liquid in a distal chamber, a second liquid in a proximal chamber, a plunger member, and a needle hub assembly coupled to a distal needle interface of the syringe body. The plunger member includes a needle retention feature disposed in a plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. Manipulating the plunger member to insert the proximal stopper member distally relative to the syringe body initially expels the first liquid, then the second liquid. The needle is at least partially retractable into plunger interior.
