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.

Medical needle shield apparatus for covering a needle after use. The medical needle shield apparatus is for use with a needle having proximal and distal ends, wherein the shield is slidably movable along the needle from a proximal position where the distal end of the needle is exposed, to a distal position where the shield covers the distal end of the needle. The shield comprises one or more clips having two or more apertures through which the needle passes, wherein the apertures have surfaces. A clip positioning member, in communication with at least one of the clips, positions the aperture surfaces of at least one of the clips when a portion of the clip positioning member in contact with the needle is advanced past the distal end of the needle such that at least a portion of the aperture surfaces of the two or more apertures binds to the needle with opposing binding forces so as to secure the shield to the needle.

604/263000, 604/198000, 600/576000

Medical needle shield apparatus including a shield with two or more segments hingedly connected to each other and movable from a retracted position where the needle is exposed, to an extended position where the shield extends beyond the end of the needle. The needle is affixed in a hub of a medical needle device, and the shield is articulated to the hub. At least one of the two or more segments has an open orifice through which the needle passes to form an axis of intersection about the needle. The shield includes a channel for covering the needle when the shield is linearly extended. One or more locks associated with one or more of the segments secures one or more of the segments relative to the shield in the extended position. A latch is also disposed on the distal segment for securing the distal segment relative to the shield when in the extended position. The number of hingedly connected segments depends upon the needle length and device length required to extend the shield beyond the distal end of the needle.

604195

Method and apparatus associated with safe retraction of medical needles after use. Embodiments are disclosed for self-retracting needle systems for both blood draw, syringe and catheter insertion systems. Invention manufacture requires only a minimal number and complexity of parts such that a projected manufacturing cost is potentially low enough to permit the apparatus to be cost competitive with contemporary non-self retracting needle systems. Methods for making and assembling each of the disclosed the embodiments is also disclosed. One blood draw embodiment can be made with as few as three molded parts. Energy-storing, needle-retracting mechanisms comprise elastic tubing and vacuum generating piston parts. In an elastic tubing embodiment, selective, constrictive control of stretched tubing volumes effectively inhibits regurgitant flow from the needle. In all embodiments, needle retraction is a single handed operation permitting a technician's other hand to be used in wound care.

A closed automatic system for removing (for facilitating the removal) and safely storing potentially contaminated medical (or other) needles in which the operator only uses one hand to operate the system. The system has a counter which counts the number of actuations of the needle sensor. When a predetermined limit is reached the device signals the operator that the safe is nearly full. A further fixed number of needles can then be removed, when that limit is reached, a fuse on the safe is blown causing the system to be inoperative until a new box is installed. Removal of the box also causes the fuse to be blown and the circuit is disabled until a new box is inserted. The safe storage box contains a tab which when fixed in the locked position can not be opened except upon the application of substantial force with a tool. The system uses a Motorola 705 EPROM or similar microcontroller. (Motorola product literature is incorporated by reference herein. ).
