<p>An assembly (10) for supporting a cannula (18) and which includes a post portion (39) which concentrically surrounds a section of the cannula (18) adjacent to the hub (38). The assembly (10) also includes a cover (46) and post portion (39) of the hub (38) to enclose the cannula (18). The cover (46) and post portion (39) are coupled together by a "tamper-proof" connection which normally resists removal of the cover (46), and thereby attests to the sterile integrity of the needle (18). The connection can be broken in response to the deliberate application of a predetermined rotational force by the user upon the cover (46) and cannot thereafter be recreated, thereby serving as an outward indication that the sterile integrity of the cannula (18) has been compromised. Both the post portion (39) and the cover (46) remain physically intact, despite the breakage of the connection, to permit the return of the cover (46) when desired.</p> |
