Abstract:
1. A cannula-tip shielding mechanism, comprising: an outer housing selectively disposed within a catheter adapter and having an adapter-interlock feature; an inner housing comprising a cannula-feature capture mechanism and a cannula-tip capture mechanism, wherein the inner housing is slidably movable within the outer housing between a first position that biases the adapter-interlock feature into an engaged position that secures the outer housing within the catheter adapter and a second position that allows the adapter-interlock feature to move to an unengaged position thereby allowing the outer housing to be removed from the catheter adapter, the second position being proximal to the first position, and wherein, when the inner housing is in the first position, a distal end of the inner housing is contained within the outer housing; and a cannula that extends into the inner housing, the cannula having a cannula feature.
