Abstract
I disclose a sharps shield for needles commonly used by dentists and plastic surgeons. The sharps shield has comprises a puncture-resistant graduated hollow cone having an open apex which reversibly wedge impacts and is hermetically sealed by the trailing end of a conical needle scabbard reversibly holding a hub-contained hollow bore steel needle sharp on each end; a mid-portion which reversibly wedge impacts the leading end of an inserted standard carpule aspirating syringe such that the trailing end of the needle can be reversibly affixed to drain a medication-containing carpule, when the conical needle scabbard is reversibly displaced; and an open trailing frustum which flares to substantially increase the internal diameter and reversibly hold a hermetically sealing cap. A similar graduated hollow cone is disclosed for shielding a Luer-Lok syringe-attachable standard hub-contained hollow-bore steel needle sharp on the leading end. Each sharps shield enables the user to conveniently affix the needle to the syringe under sterile conditions inside the mid-portion of the graduated hollow cone; to safely shield the syringe-attached needle inside the mid-portion of the graduated hollow cone before and between uses on a patient; and to safely dispose of the sharp needle after hub reinsertion into the needle scabbard reversibly wedge impacted in the open apex of the graduated hollow cone.
