Mult-beveled point needle and syringe having a multi-beveled point needle

A needle having a multi-beveled point comprising a needle cannula having a central axis, an outer diameter in the range of 0.0130″-0.0135″, and an inner diameter in the range of 0.0075″-0.0090″, said needle cannula having a multi-beveled point including a plurality of planar bevels extending at different angles of rotation relative to said central axis, including a primary bevel, a pair of tip bevels and a pair of middle bevels intermediate said primary bevel and said tip bevels.

A syringe assembly comprising:

• a syringe barrel;
• and,
• a needle cannula supported by said syringe barrel and having a multi-beveled point, said needle cannula having a central-axis, an outer diameter in the range of 0.0130″-0.0135″, and an inner diameter in the range of 0.0075″-0.0090″, said needle cannula having a lumen and a central axis therethrough, said multi-beveled point provided at one end of the cannula, said multi-beveled point comprised of a primary bevel, a pair of tip bevels, and a pair of middle bevels, wherein respective of an angle defined between said central axis and a reference plane, each of said primary bevel, said pair of middle bevels, and said pair of tip bevels are provided on said cannula at a respective planar angle, wherein said planar angles of said primary bevel and said pair of middle bevels are substantially equal.

A syringe assembly comprising:

• a syringe barrel;
• and,
• a needle cannula supported by said syringe barrel and having a multi-beveled point, said needle cannula having a central axis, an outer diameter in the range of 0.0130″-0.0135″, and an inner diameter in the range of 0.0075″-0.0090″, said multi-beveled point comprised of five bevels, wherein each of said five bevels is provided on said cannula at a planar angle defined between said central axis and a reference plane, and wherein each of said five bevels is provided on said cannula at an angle of rotation about said central axis, wherein two of said planar angles are substantially equal.

A syringe assembly comprising:

• a syringe barrel;
• and,
• a needle cannula supported by said syringe barrel and having a multi-beveled point, said needle cannula having a central axis, an outer diameter in the range of 0.0130″-0.0135″, and an inner diameter in the range of 0.0075″-0.0090″, said needle cannula having a lumen extending from a first end of said cannula and having an opening defined through said first end, said multi-beveled point comprised of a point with first, second, third, fourth and fifth bevels bounding said opening, said first bevel contiguously extending between said fifth and second bevels, said second bevel contiguously extending between said first and third bevels, said third bevel contiguously extending between said second and fourth bevels, said fourth bevel contiguously extending between said third and fifth bevels, and said fifth bevel contiguously extending between said fourth and first bevels, wherein said first and third bevels each have a greater length than said second bevel.

A syringe assembly comprising:

• a syringe barrel;
• and,
• a needle cannula supported by said syringe barrel and having a multi-beveled point, said needle cannula having a central axis, an outer diameter in the range of 0.0130″-0.0135″, and an inner diameter in the range of 0.0075″-0.0090″, said cannula having a lumen, said lumen extending from a first end of said cannula and having an opening defined through said first end, said first end terminating in a point with a plurality of discrete bevels bounding said opening, wherein one of said plurality of discrete bevels is located furthest from said point and has a length shorter than any of said other ones of said plurality of discrete bevels.
