摘要： A syringe assembly including a needle cannula having a five-beveled point and a needle shield formed of a styrene block poly(ethylene/butylene) thermoplastic elastomer which significantly reduces needle penetration force and may reduce the cycle time for gas sterilization. The multi-beveled needle cannula point includes a primary bevel, a pair of tip bevels and a pair of middle bevels each intermediate the primary bevel and a respective tip bevel, wherein the angles of rotation of the primary bevel and the intermediate bevels are substantially equal resulting in reduced heights of intercepts between the bevels, therby reducing needle penetration force. The needle shield maintains the sharpness of the needle cannula during application, sterilization and removal of the shield and it is believed that the needle shield will also reduce the cycle time of gas sterilization as compared to rubber needle shields and vulcanizate thermoplastic elastomers.

摘要翻译：一种注射器组件，其包括具有五斜面的针插管和由苯乙烯嵌段聚（乙烯/丁烯）热塑性弹性体形成的针护罩，其显着降低针穿刺力并且可减少气体灭菌的循环时间。所述多角针插管点包括主斜面，一对尖端斜面和一对中间斜面，每个中间斜面均在所述主斜面和相应的尖端斜面之间，其中所述主斜面和所述中间斜面的旋转角度基本相等导致斜面之间的截距的高度减小，从而减少针的穿透力。针护罩在施加，消毒和除去护罩期间保持针管的清晰度，并且相信与橡胶针护罩和硫化橡胶热塑性弹性体相比，针罩还将减少气体灭菌的循环时间。

摘要： A hypodermic needle featuring a multi-beveled point geometry is disclosed. In one embodiment, the multi-beveled point features a primary bevel, a pair of tip bevels, and a pair of middle bevels each intermediate the primary bevel and a respective one of the tip bevels. The primary and middle bevels are provided at angles of inclination, measured between 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 transitions between the respective bevel faces, lessening the penetration force required to urge the needle point through skin, flesh, or other material.
