Three embodiments of a single-step lancet are disclosed. Each such lancet embodiment provides true one-step operation. In a single operational step requiring only a unidirectional displacement of an actuator into a housing, a lancet blade is removed from an aseptic environment which protects and retains the lancet blade in a pre-sterilized state within the housing prior to use, stores energy in an energy storage medium, activates the lancet blade to perform a lance and for safety retracts the lancet blade into the housing.

Single-step disposable safety lancet apparatus and methods

A retractable and extendable medical needle protective shield which provides opportunity for accessing and reaccessing a medical needle and associated sharpened needle tip and recovering the needle and tip for safety between accesses. The shield includes a needle guide which assures the needle tip is untouched by any part of the shield as the shield is displaced to cover and uncover the needle. A releasible latch is provided to guard against inadvertent removal of the protective shield between accesses. An unreleasible latch is also provided to secure the shield relative to the latch preparatory to final disposal. In combination with the protective shield, a plurality of adapters are disclosed which provide examples of passively operated, protected access to membrane pierceable fluid sources such as a &ldquo;Y&rdquo; connection site of an IV set line, a drug vial, a vacuum sample tube, an umbilical cord holder and a hypodermic site.

Reaccessible medical needle safety devices and methods

An invention which provides for making low cost apparatus and one-hand activation methods for shielding a syringe needle as a safety precaution after each needle use. A shield, which may be used as a protective cover for the needle during initial transport to site of use, is linearly actuated to three distinct stops by action of a single hand, thereby leaving the second hand of a user free for patient care. The shield is releasible from two of the three stops to make possible uncovering of the needle preparatory to use and temporary needle protection between needle uses. The shield has an elongated hollow barrel shape which is sized to fit snugly about, yet slide smoothly over a body of a syringe associated with the needle. The barrel shape of the shield is longitudinally interrupted by a scissure in which an arm which is hingeably affixed to the shield resides. The arm is selectively bent to provide operative surfaces which permit the shield to be released from two of the three stops and further displaced to selected stops by inward depression of the arm. The invention utilizes a collet with a slot and a pawl which interacts with at least one set of ratchet teeth on the arm to provide one of the releasible stops. Generally release from stops is actuated by inward pressure on a predetermined portion of the arm.
