1. A needle retraction apparatus comprising:
a body having a forwardly projecting needle;
a needle retraction mechanism seated inside the body and biasing the needle rearwardly relative to the body;
a slide member disposed rearwardly of the body and attached in slidable engagement to the body and having a first opening communicating with a needle retraction cavity projecting away from the body; and
a needle retraction tube containing the needle retraction cavity, the needle retraction tube being supported by the slide member and rotatable relative to the slide member and the body to reposition the slide member from a first position preventing needle retraction to a second position permitting needle retraction into the needle retraction cavity;
wherein the slide member is configured to move transversely relative to the body between the first position and the second position.
