Needle guard, and assembly
First Claim
1. An assembly of a needle guard for a hub and attached needle, comprising:
- an elongate guard member mounted on the hub for rotatable movement thereon, the guard member including an elongate, longitudinal slit adapted to interfit with the needle prior to use, the guard member defining engaging means for a rotatable locking member; and
,a locking member mounted on the guard member, and adapted for rotational movement therealong, the locking member providing an elongate slit coinciding with the slit of the guard member;
whereby;
i. prior to use, the needle is adapted to interfit into the slit of the guard member;
ii. during use, the guard member and attached locking member are adapted to rotate away from the needle;
iii. following use, the guard member and attached locking member are adapted to rotate back to interfit with the used needle; and
,iv. the locking member is adapted to be rotated around the needle guard and rotatably locked therewith while moving the locking slit out of alignment with, and to occlude the needle, thereby protecting against accidental needle stick injuries.

Abstract
A needle guard is provided to protect against accidental needle stick injuries following use, and to provide a cover for the needle when shipping.
The needle guard is rotatably mounted at the base of the needle and defines a longitudinal slot which coincides with the needle. When the needle is ready for use, the needle guard is rotated away from the needle; following use, the guard is rotated back to partially enclose the needle. A slotted cylinder is then moved forwardly along the needle guard and is rotated for a short distance to lock and permanently enclose the needle, and particularly the tip portion thereof.
In another embodiment, a rotatable sleeve is provided to interlock with the needle guard and permanently enclose the needle.
The device may be adapted for use with over-the-needle catheters, and its use facilitates attachment of other devices such as vacutainers to the needle and hub assembly.
