Compact injector system and method

Abstract

Devices and methods are provided for a compact injector having a compact configuration for easy portability or storage and an activated configuration ready for injection. In the compact configuration, both the plunger and needle are retracted into the syringe housing, and when actuated to the activated configuration, the plunger extends proximally and the needle extends distally in preparation for injection . An extendable needle shield is also provided to block visibility of the needle during injection and reduce the risk of accidental needle stick injuries at other times, including when discarding.
