Abstract
A needle guard attachment for a syringe. The guard has a pair of concentric members one of which establishes fluid communication between the needle and the syringe body. The other member slides to cover the needle. Once in an extended position it locks into place to act as a sheath over the needle. The guard attaches to the needle and the syringe body by luers compatible to those already on the elements.
