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.
