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:
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.

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.
