6. The automatic injection and retraction device as in claim 5, wherein, after movement of said pre-filled syringe cartridge said predetermined distance, said temporary engagement feature is configured to release from said injection assembly so that said injection assembly is drivingly engaged to said piston of said pre-filled syringe cartridge.
7. An automatic injection and retraction device having a longitudinal axis, comprising:
an injection assembly having an activation sub-assembly and an injection sub-assembly, said activation sub-assembly being rotatable with respect said injection sub-assembly about the longitudinal axis but not moveable with respect to said injection sub-assembly along the longitudinal axis;
a retraction assembly having a retraction sub-assembly and a needle guard, said needle guard being moveable with respect said retraction sub-assembly along the longitudinal axis but not rotatable with respect to said retraction sub-assembly along the longitudinal axis; and
a pre-filled syringe cartridge having a hypodermic needle with a needle sheath thereon, said retraction assembly being secured to said injection assembly so that said pre-filled syringe cartridge is disposed in said retraction assembly with said needle sheath secured to said needle guard,
wherein said needle guard having said needle sheath secured thereto is removed from said retraction sub-assembly in a direction along the longitudinal axis upon application of a twisting torque to said activation sub-assembly and said needle guard about the longitudinal axis.
8. The automatic injection and retraction device as in claim 7, wherein said injection assembly further comprises an activation-prevention feature moveable between an on position and an off position.
9. The automatic injection and retraction device as in claim 8, wherein said activation-prevention feature is moved from said on position to said off position simultaneously with said needle guard and said needle sheath being moved in said direction upon application of said twisting torque.
10. The automatic injection and retraction device as in claim 8, wherein said activation-prevention feature is configured to prevent movement from said off position to said on position.
11. The automatic injection and retraction device as in claim 7, wherein said retraction sub-assembly, after use, is configured to permanently receive said needle guard having said needle sheath secured thereto so that said hypodermic needle is enclosed within said retraction assembly.
12. The automatic injection and retraction device as in claim 7, wherein said activation sub-assembly comprises an activation button and a cap, said activation button being received in said cap so that said activation button is moveable with respect said cap along the longitudinal axis but not rotatable with respect to said cap along the longitudinal axis.
