    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： A single-use hypodermic syringe which locks up after one use. There is a body having a cylindrical container for holding a fluid. A hollow needle communicates with an interior of the cylindrical container through one end and a sliding plunger disposed in the cylindrical container is connected to a plunger rod disposed through an opposite end of the cylindrical container. There is locking apparatus allowing the plunger to move only in a direction towards the one end whereby after the plunger is moved adjacent the one end, it cannot be withdrawn for subsequent use. In one version, the plunger has a locking plate attached thereto. In another version, a hooked plate at the end of the cylindrical container digs into and grips an end bore of the plunger. In still another version, the plunger rod is gripped and held if movement to withdraw the plunger is attempted. Both disposable and carpule-using versions are disclosed.

    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 needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. In one implementation the needle guard has an elongate containment member that rides with the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being refracted into the needle guard.
