ABSTRACT:
An epidural or anesthesia needle assembly having a "wing" selectively attachable to the needle hub is disclosed. The "wing" is made of a sturdy but resilient material. The "wing" has a tang for placing in a corresponding slot in the needle hub to ensure the correct orientation of the "wing" with the bevel tip of the cannula. In addition, the tang allows the "wing" to be pushed along the elongated axis of the cannula with improved efficiency so that the "wing" does not become inadvertently detached from the needle hub. In the preferred embodiment, the "wing" includes a protective sheath mount enclosure shaped in contour to the protective sheath mount located at the most distal end of the needle hub. The protective sheath mount enclosure forms a lock around the protective sheath mount. The contour shape of the protective sheath mount enclosure encloses the protective sheath mount so that as the "wing" is moved either proximally or distally, the resilient material of the "wing" around the protective sheath mount enclosure moves into locking contact with the protective sheath mount.
