Abstract: A system for injecting includes a syringe body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the syringe body, the plunger member. The plunger member includes 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. The system further includes a needle hub assembly coupled to the distal needle interface of the syringe body. 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. The needle is at least partially retractable into plunger interior. The needle proximal end feature includes an annular distally facing surface.

Abstract: A system for measuring injection of a liquid medicine includes a syringe body having proximal and distal ends, a syringe interior, and a syringe flange at the proximal end thereof. The system also includes a stopper member disposed in the syringe interior. The system further includes a plunger member coupled to the stopper member and configured to be manipulated to insert the stopper member distally in the syringe interior relative to the syringe body. Moreover, the system includes a needle coupled to the syringe body at the distal end thereof. In addition, the system includes a sensor flange removably coupled to a syringe body. The sensor flange includes a sensor to measure an injection characteristic and a processor to analyze the injection characteristic to determine an occurrence of an injection event.
