Filed:
Feb 4, 1991

7/650419

Abstract:
A guard mechanism for a medical needle has a hub and a hollow needle portion. The guard includes a tubular sheath, a spring within the sheath which biases the hub to draw the needle into the sheath. Jaws project from an end of the sheath for gripping the needle portion to prevent the spring from drawing the needle portion into the sheath. A body surrounds the sheath for grasping and holding the guard mechanism, and has a port through which the jaws project, the jaws being resiliently biased to bear against the port, such that when the sheath is moved toward the port, the jaws slide out from the port and are thereby freed to resiliently expand, thereby releasing the needle portion and permitting the spring to withdraw the needle portion into the sheath.
