ABSTRACT:
I describe a an elastomeric tube whose leading end holds a tubular puncture-resistant needle shield by means of elastic recoil and whose trailing end attaches by elastic recoil to the conical hub of a hollow needle. A removable cylindric hub-cap initially covers the elastomeric tube surrounding the needle. The purpose of the assembly is to sustain needle sterility after filling from a vial and before use in a patient, as well as to prevent accidental needle sticks after use in a patient. The user attaches the tubular assembly to a Luer-Lok on a syringe or onto the leading end of tubing used for transferring fluids. He/she removes the cylindric hub-cap and inserts the needle tip into a penetrable vial cap for filling and later discharge into a patient, another vial or a capped IV infusion port. The tubular needle shield slides back over the shaft of the needle with penetration of skin or a capped vial surface, while the elastomeric tube shortens like an accordion. When the user retracts the needle from the capped vial or from a patient, elastic recoil in the tube causes the conical needle shield to slide back and automatically re-shield the exposed shaft and beveled tip.
