A device for rotational connection between structural members. A generally cylindrical housing may have a central cavity therein with an open bearing end and an open plug end. A shaft at a first end may be inserted into a bearing and retained therein. The bearing may be disposed in the open bearing end and retained by a first fastener ring. A second end of the shaft may protrude outwardly from the housing through the open bearing end. A plug may be threadably engaged with the open plug end that is threaded. The plug may be positioned at an interior end to be adjacent the first end of the shaft that may have a convex surface.

Rotational connector device

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.

Needle tip guard for percutaneous entry needles

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.

Intravenous catheter assembly

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.

Single use syringes

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.

Springs and locking collars for retractable sleeve-protected injection

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.
