Method of making a needle shield assembly
First Claim
1. A method of making a needle shield assembly comprising the steps of:
- (a) providing a needle shield and collar assembly comprising a collar having an aperture therethrough of at least 180°
duration and an elongate needle shield having a distal end and a proximal end hingedly connected to said collar, said needle shield including two sidewalls defining a longitudinal opening;
(b) providing a needle cannula having a proximal end, a distal end and a lumen therethrough;
(c) providing a hub having a proximal end for connecting to a fluid transfer device and a distal end for connecting to the proximal end of said needle cannula;
(d) providing a base member having collar retaining portion configured to accept said collar through its aperture;
(e) providing a rigid elongate needle cover having a distal end, an open proximal end and a sidewall therebetween defining a cavity;
(f) attaching said base member to said hub;
(g) attaching said proximal end of needle cannula to said hub;
(h) placing said needle cover over said needle cannula and advance said needle cover until said proximal end of said needle cover removably engages said hub;
(i) connecting said collar to said needle hub by advancing said collar axially over said needle cover toward said hub until said collar engages said collar retaining portion of said base member, said collar and needle shield assembly being oriented with said hub so that when said needle cover is removed from said needle hub, said collar is capable of pivoting from an open position where said needle cannula is exposed, to a closed needle protecting position where said needle cannula is within said longitudinal opening of said needle shield.

Abstract
A needle shield assembly having a single-use cannula lock of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough. A hub includes a proximal end for connection to a fluid transfer device and a distal end connected to the proximal end of the needle cannula. A collar is rotationally connected to the hub so that the collar can be rotated around the hub. An elongate needle cover removably engages the hub and covers the needle cannula. An elongate needle shield having a proximal end and a distal end is hingedly connected, through its proximal end, to the collar. The needle shield includes two sidewalls defining a longitudinal opening and a back wall between said side walls defining a recess having an interior surface. The needle shield is capable of pivoting from an open position wherein the needle cannula is exposed, to a closed needle protecting position wherein at least part of the needle cannula is within the longitudinal opening of the needle shield. The needle shield assembly further includes structure for preventing the needle shield from pivoting into the closed position unless the needle cover is removed, and structure for locking the needle shield in the closed needle protecting position when the needle shield is pivoted into the closed position. The structure for locking traps the needle cannula in the longitudinal opening of the needle shield.
