The five-bevel tip geometry of the hypodermic needle

The invention relates to a hypodermic needle characterized by a five-bevel tip geometry. The five bevel tips are characterized by a main bevel, a pair of tip bevel and a pair of middle bevel, each middle bevel is located between the main bevel and a corresponding tip bevel. The geometry of the bevel tip allows for the formation of continuous intersecting lines or transitions between the bevel surfaces, thus reducing the puncture force required to pass the tip through skin, muscle, or other materials.
