FIVE BEVELED POINT GEOMETRY FOR A HYPODERMIC NEEDLE

摘要

A hypodermic needle featuring a multi-beveled point geometry is disclosed. In on e embodiment, the multi-beveled point features a primary bevel, a pair of tip beve ls, and a pair of middle bevels each intermediate the primary bevel and a respective one of the ti p bevels. The primary and middle bevels are provided at angles of inclination, measured betwee n the central axis and a reference plane that are substantially identical. The tip bevels are formed at an angle of inclination respective to the central axis which is not equal to the angle of inclination at which the primary and middle bevels are formed. The resulting five-beveled point geometry contributes to a more continuous bevel face free of abrupt intercepts or transit ions between the respective bevel faces, lessening the penetration force required to urge the nee dle point through skin, flesh, or other material.
