Abstract

An apparatus for collecting a body fluid for testing for an analyte includes a needle for penetrating a patient'"'"'s skin to access the fluid within the skin. The needle has a hollow body extending from a first end to a second end. An interior surface of the body defines a fluid pathway extending between the ends. The second end is positioned to deposit fluid for testing. The first end has a beveled face on a front side of the body. The beveled face terminates at a penetration tip with the beveled face having an opening in communication with the fluid pathway. The penetration tip is burnished to a rounded shape and bent to facilitate low pain and rapid fluid collection.

Claims

1. A method of forming a needle having a bent tip, the method comprising:

providing a body having a wall defining a lumen and an exterior surface, said body comprising a penetration end having a beveled face wherein the intersection of said beveled face and said wall forms a penetration tip; and

bending said beveled face to displace said penetration tip beyond said exterior surface.

2. The method of claim 1 wherein:

said body has a front side and a back side and said beveled face is positioned on said front side; and

said beveled face is bent at an angle in the range from about 20° and

about 40°

.

3. The method of claim 1 wherein said bending comprises:

placing a fulcrum at a selected location on said beveled face;

urging said beveled face towards said fulcrum whereby said beveled face is bent at said selected location and said penetration tip is displaced beyond said exterior surface.

4. The method of claim 1 wherein said beveled face has inner and outer peripheral edges, the method further comprising:

dulling said inner and outer peripheral edges.
