ABSTRACT:
I describe a puncture-resistant hollow cone with a leading tether, a slanted leading aperture and a trailing bore of decreasing diameter for shielding and preventing accidental injuries from a hollow-bore steel needle after use for giving an intravenous (IV) infusion or withdrawing blood through trailing tubing. When the puncture-resistant hollow cone is slid over trailing tubing to overlie the needle hub, and the tether is held down with one finger over a venipuncture site, the other hand retracts trailing tubing attached to the needle hub until the trailing end of the needle hub becomes wedge impacted in the trailing bore of the puncture-resistant hollow cone, leaving the needle shaft and tip safely shielded within the leading bore of the puncture-resistant hollow cone in a space inaccessible to a user's finger.
