Lancet needle anchor and method
First Claim
1. A lancet for use with a lancing device, said lancet having a body, a needle or blade positioned therein, and a needle cover, the body and needle cover being unitarily formed from plastic, characterized by:
- said needle or blade having an elongate body portion, one end of which is sharpened, and the other end of which is bent at an angle substantially perpendicular to the body portion thereof;
the body portion of the plastic molded around the needle having opposed ports, said ports being formed by the withdrawal of opposed clamping members which secure the needle in place interiorly of the plastic mold when the plastic is formed about the needle, said opposed ports revealing the needle body portion interiorly thereof as a result of having been previously clamped in a jig interiorly of the mold cavity from which the body of the lancet is formed.

Abstract
A lancet body 15 is molded around a needle or blade, in which the inner end of the needle body which is unsharpened has an L-shape bend at the unsharpened end. The bend, when embedded in the plastic which forms the body of the lancet, secures the needle against removal. The method involves the bending substantially perpendicularly of the unsharpened end of the lancet needle or blade to be substantially perpendicular with the elongate body of the blade. The needle or blade is placed within a jig interiorly of the plastic mold. The jig includes spaced opposed clamps and a single orienting support to the bent portion of the needle. The body of the lancet is relieved in many areas to reduce material cost and has a molded tab cover eliminating a loose part such as a separate cover.

a plurality of four runners extending along the body of the lancet; said runners being at essentially perpendicular and dimensionally opposite distances from each other;
whereby the lancet body when secured in the lancing device can be ensured of a direct linear movement when fired by engagement of the lancing device.

3. In the lancet according to claim 2,
wherein said ports penetrate opposed runners and are proportioned to accommodate said clamping members interiorly of the mold from which the lancet is formed, said clamping member being also proportioned when removed to leave said ports for inspection and weight reduction in the opposed runners extending to the needle from the outer edges of the runners. -
4. In the lancet according to claim 2, the plastic for forming said lancet being selected from that type of plastic known as LDPE, grades Q200, virgin or reclaimed.
