Abstract: Embodiments described herein include a safety system including a needle guard assembly, where the needle guard assembly can be configured for attachment to a needle retaining device having a proximal end, a distal end, where a needle can be fixedly coupled to the distal end. The needle guard assembly can include a first cylinder, where the first cylinder can be attached to the distal end of the needle retaining device. The needle guard assembly can include a second cylinder, where the second cylinder can be selectively movable relative to the first cylinder from a first position, to a second position wherein the needle is fully exposed, to a third position where the needle is fully covered.
