    摘要： A needle tip protective device for use with percutaneous entry needles. In one embodiment, the needle tip protective device includes a needle guard slidably mounted on a hypodermic needle, the latter having a needle tip located at the distal end thereof, and a change of profile formed medially there along. The needle guard is movable along the hypodermic needle and engageable with the change in profile formed thereon. The engagement with the change in profile is configured to correspond with the ability of the needle trap to entrap the needle tip once the needle trap has advanced the sufficient distance distally along the hypodermic needle. In further refinements, the needle trap may be biased toward the distal needle tip of the needle.

    摘要： A single use syringe in which the single use aspects are accomplished by a lumen spike which is forced into the lumen bore to seal the passageway from the syringe body to the hypodermic needle. Fail-safe characteristics to prevent bypassing the single use provisions are provided by having a frangible area of the endwall holding the lumen break out at a force less than that required to force the lumen spike out of the lumen bore. This aspect can also be used to improve other approaches to single use syringes. The lumen spike can be formed as part of the piston/plunger and the piston/plunger can be a unitary device useful in all syringes.

    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.
