Pivotable guard for shielding a needle
First Claim
1. A needle guard assembly for protectively enclosing a needle cannula comprising:
- a needle cannula having a proximal end and a sharp distal end;
a guide securely attached in proximity to said proximal end of said needle cannula;
a cover hingedly connected to said guide for pivoting between a first cover position where said needle cannula is at least partly enclosed by said cover and a second cover position where said needle cannula is exposed for use; and
a slide slidably engaged with said guide for movement between a first slide position where said guide is slidably engaged with said cover when said cover is in said first cover position, such that said slide and said cover surround said needle cannula and a second slide position where said slide is spaced from said cover.

Abstract
A needle guard assembly is provided for mounting to the hub of a needle assembly. The needle guard assembly includes a guide that is engageable on the hub. An elongate U-shaped cover is hingedly mounted to the guide and can be rotated from a first position where the needle cannula is substantially surrounded by the U-shaped walls of the cover into a second position where the needle cannula is exposed for use. The needle guard assembly further includes a slide that is slidably engaged in the guide and movable from a first position where the slide cooperatively engages the cover for completely surrounding the needle cannula to a second position where the slide is spaced proximally from the cover, thereby permitting the cover to rotate into its second position.

10. A needle guard assembly for protectively enclosing a needle cannula including:
- p1 a guide having a channel;
p1 a cover with a side opening mounted to the guide for pivoting movement between a first position in which the needle cannula is exposed for use and a second position in which the needle cannula is at least partially enclosed by the cover and partially exposed through the side opening; and
p1 a slide slidably engaged to the channel of the guide and movable between a first position in which the slide is disposed in the side opening and a second position in which the slide is not in the side opening. - View Dependent Claims (11, 12)
