Lancet needle anchor and method
First Claim
1. A lancet for use with a lancing device 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 hereof;
the body portion of the plastic molded around the needle having opposed recesses, said recesses being formed by the withdrawal of opposed clamping members which secure the needle in place of the plastic mold when the plastic is formed above the needle, each opposed recesses 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.

2. A method of forming a lancet having a needle or blade within an elongate lancet body, produced in accordance with the following steps:
-
bending one end of said needle or blade body, and sharpening the other end to form a point;
forming a mold for the lancet body which forms a cavity complementary to the shape the lancet body including forming a cap portion to encapsulate the sharp end of the needle blade;
providing opposed clamping members at an interior portion of the mold in vise-like relationship to the lancet body of the needle or blade;
injecting plastic into the mold after the lancet body has been positioned therein; and
thereafter opening the mold and removing the lancet;
whereby the lancet is sanitarily housed within the lancet body with the needle or blade point encapsulated in the head and revealing, through the recesses in the body left by the withdrawal of the jig, opposite sides of the body on the needle or blade. - View Dependent Claims (5)
