Abstract: The invention of the present disposable adjustable lancet involves an assembly which has a body and a cap. A lancet holder fits in the body and has a base portion having a pair of upstanding retainer-disabling tines, one of the tines is longer than the other to block the reinsertion of the lancet. A selector tip assists in engaging a clicker position in the selector tip. The method involves selecting positions by means of a female and a male position clicker which provide an audible signal. The position of the lancet can be determined in three manners: visually observing the degree of rotation, audibly denoting the click, and physically rotating the member which, in turn, results in a reaction on the finger while the adjustment is being made.

Abstract: A syringe carrying a needle with a barrel and hollow piston for dispersing an injectant through the end of the retractable needle. A resilient chuck seal is independently formed for positioning at the transition from the syringe barrel to the needle shank holding portion of the end of the barrel. The needle is propelled by the coaxial spring into the interior portion of the piston and totally retracted when the chuck seal is released. The method of the present invention relates to the use of a symmetrical chuck seal, annular in configuration, for not only gripping the head of the retractable needle, but simultaneously serving as the seal for the needle at the lower portion of the barrel so that the injectant escapes through the hollow syringe needle.

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.
