Abstract
Abstract The present invention is directed toward an improved spinal needle. A needle hub is disposed about a proximate end of a hollow needle. The needle hub side port indicators provide visual and tactual verification by a user of the orientation of the side port on the needle. The needle hub also includes a window with a magnified view. The invention provides a stylet cap disposed about a proximate end of a stylet that freely slides inside the hollow needle and needle hub. The stylet cap forms a pressure fit with the needle hub, and can be engaged in the pressure fit from any axial orientation.
