    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 medical needle shield apparatus is provided which includes an extensible shield having a first segment and a second segment extending therefrom. The second segment includes an opening configured for clearance of a medical needle of a medical needle device during attachment of the extensible shield to the medical needle device. The second segment defines a planar surface adjacent a distal portion thereof. The planar surface is configured to engage the needle for disposing the shield in an extended position. In alternate embodiment, the medical needle shield apparatus has a syringe having a needle hub supporting a needle. The first segment articulates from a collar disposed about the needle hub. The collar includes a pair of latches. The opening is configured for travel about the needle to facilitate extension of the shield from a retracted position to an extended position. The second segment further includes a proximal fulcrum that engages the needle to facilitate extension of the shield. The second segment also has a pair of catches. The catches are engageable with the latches to maintain the shield in the retracted position. The second segment has a nose portion defining a planar surface configured to engage the needle to facilitate fixing the shield in the extended position.

    摘要： A medical needle shield apparatus is provided which is slidably movable along a medical needle from a proximal position where a distal end of the needle is exposed, to a distal position where the shield protects the distal end of the needle. The medical needle shield apparatus includes a binding member having an aperture through which the needle passes. The binding member also has binding surfaces for binding to a medical needle. The shield apparatus also includes a retainer integral with the binding member and in communication with the needle for temporarily retaining the binding surfaces in a non-binding position relative to the needle. The shield apparatus also includes a positioning member for positioning the binding surfaces to secure the shield to the needle when a portion of the retainer in contact with the needle is advanced past the distal end of the needle. A housing may be included for enclosing the shield apparatus.

    摘要： A needle safety apparatus is disclosed which includes an inner bearing disposed within an outer bearing. The inner bearing is moveable to extend telescopically in a first interior space defined by the outer bearing. A second interior space is defined by the inner bearing, while extendable linkage segments connect the hub to the inner bearing. A hub retains the proximal end of a needle, while the distal end of the needle extends through the second interior space. A wedging portion is movable with the inner bearing and pivots to secure the distal end of the needle within the second interior space when the distal end of the needle is retracted therethrough. A latch may be formed in the inner bearing to obstruct the first interior space and prevent the inner bearing from retracting therethrough.
