Lancet needle anchor method
DCFirst Claim
1. 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, 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 sharpened end of the needle or blade;
providing opposed clamping members at an interior portion of the mold in vise-like relationship to the needle or blade;
injecting plastic into the mold after the needle or blade has been positioned therein; and
thereafter opening the mold and removing the lancet;
whereby the needle or blade is sanitarily housed within the lancet body with the needle or blade point encapsulated in the head and revealing, through the recesses in the lancet body left by the withdrawal of the jig, opposite sides of the needle or blade.

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 a lancet body, including the steps of:
-
a) providing a needle or blade having a first sharpened end and a second end remote from said first end;
b) providing a bend in said needle or blade remote from said first end;
c) providing a mold with at least one cavity configured to create said lancet body;
d) clamping said needle or blade within said at least one cavity with a clamp engaging said needle or blade from opposed sides thereof;
e) injecting plastic into said mold, said plastic encapsulating said bend and surrounding said clamp;
f) removing said lancet. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
