    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. A soft rubber seal inside the cover's closed end seals the needles of pre-filled devices against leakage. A pierceable capsule carried by the outside of the closed end of the cover contains a sealing material that can be used to seal the needle against further use.

    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.
