    摘要： A needle tip protective device. In one embodiment the needle tip protective device includes a needle guard that is slidably mounted on a hypodermic needle having a needle tip located at the distal end of the needle. The needle guard contains a movable needle trap that is biased against or toward the hypodermic needle. The needle trap advances over the tip of the needle, entrapping the needle tip as the needle guard is urged forward near the sharpened distal end of the hypodermic needle. A tether, or other limiting means, limits the forward movement of the needle guard along the needle. In one embodiment, the needle guard is manually urged forward along the shaft of the needle by the user. In yet another embodiment, a spring, or other biasing means, is used to move the needle guard along the shaft of the needle.

    摘要： This invention is directed to covers for holding and protecting needles of medical devices prior to use. It includes covers for holding and protecting needles of medical devices in which the needles are, in turn, contained within a retractable protective sleeve. In such case, the needle and its protective sleeve are held within the cover by a wedging action of a base portion with the cover. The cover contains projections which grip the base so that the needle and its protective sleeve can be turned with the cover to twist them on and off of the medical device safely. Longitudinal vanes in the cover can be included to hold a spring and locking collar over the protective sleeve in a retracted state prior to use. A cap with a flat end and square shoulders is aligned with a flat side of the cover and the entirety closed with a frangible security strip to indicate any possible tampering prior to use.

    摘要： This is an all-plastic protective sleeve for the needle of a medical device. It comprises, a plastic base carrying a bottom end of the needle; a plastic end-cap slidably mounted on the needle adjacent a tip end thereof; a plurality of longitudinal plastic slats extending from the base to the end-cap; a cylindrical plastic locking collar disposed over the plurality of longitudinal slats adjacent the end-cap; and, a plastic spring disposed over the plurality of longitudinal slats between the base and the end-cap. The spring is a unitary plastic helical compression spring comprising a cylindrical collar portion disposed over a center portion of the plurality of longitudinal slats with first and second portions of helical compression spring turns extending therefrom toward the base and the locking collar, respectively. The locking collar has an outside diameter larger than the outside diameter of the spring and is of a thickness sufficient to produce a textured grippable area at the periphery thereof.
