    摘要： 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 “Y” connection site of an IV set line, a drug vial, a vacuum sample tube, an umbilical cord holder and a hypodermic site.

    摘要： A safety medical needle device comprising a mechanism for releasing a latch which holds the needle in place and manually retracting the needle and its sharpened tip into safe containment in one continuous operation. The device may be made from but a single molded part. In the case of a single molded part, the device may consist of a molded body, a medical needle and a protective tube for the needle. The device preferably comprises a pair of winged attachments for use as a medical butterfly apparatus.

    摘要： A medical needle shield apparatus is provided that includes a needle hub having an outer needle cannula extending therefrom. An inner needle is disposed for slidable movement with the outer needle cannula. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the inner needle. The shield includes a binding member disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the inner needle. The binding member includes at least one drag inducing member that engages the inner needle during slidable receipt to create a drag force. The drag force facilitates rotation of the binding member such that the binding surfaces engage the inner needle to prevent slidable movement. The binding member further includes a needle communicating surface extending therefrom that is engageable with the inner needle to prevent rotation of the binding member. A retainer extends transversely from the needle communicating surface for releasable engagement with the needle hub.
