Abstract
An improved cannula with needle which provides improved support between the cannula and the syringe. The cannula provides a base member which is substantially perpendicular to the wall member forming the edge of the barrel. In this manner, lateral forces applied to the barrel of the syringe are efficiently transferred to the cannula without causing undue force upon the syringe's nozzle or the side portion of the barrel wall. Further, the cannula attaches to the outside of the syringe nozzle. Preferably, this attachment is accomplished by a thread which engages the exterior of the nozzle as the cannula is twisted onto the nozzle. Another embodiment of the invention allows the needle portion to be attached to the nozzle through a luer-lock arrangement and then the support member applied over the needle arrangement. Still another embodiment creates a locking mechanism to the nozzle which is secured both at the inside and the outside of the nozzle.
