Abstract:
A syringe needle assembly including a needle having at least one point for use in a syringe assembly, including a needle shaft with at least one point at one end for entering the patient and one end for engaging the syringe, and a puncture-proof sheath surrounding a major portion of the needle shaft and normally extending substantially the entire length of the shaft while leaving said needle point exposed, the sheath including at least one radially expanded inner portion joined by a portion attached to said shaft, the radially expanded portion being axially compressible to force the sheath to slide in the direction of said point along said shaft to extend beyond and non-retractably cover said point. The present invention is specifically adapted to sheath a single pointed or double pointed needle.
