Needle cover management and needle obscuring devices for injection systems and methods

A system for injection, comprising:

• a syringe body having proximal and distal ends and defining a syringe interior;
• a stopper member disposed in the syringe interior;
• 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;
• a needle hub assembly coupled to the syringe body at the distal end thereof and comprising
• a needle hub, and
• a needle coupled to the needle hub;
• a needle obscuring assembly removably coupled to the needle hub over the needle and comprising;
• a liner coupled to the needle hub, and
• a needle obscuring member slidably disposed on and movable relative to the liner, the needle obscuring member configured to be disposed at least partially over the needle;
• and
• a safe retraction system configured to retract the needle at least partially within the syringe body after an injection with the system is completed such that a distal tip of the needle is disposed within the needle hub or the syringe body.
