Abstract
A breakaway intravenous needle device, including a syringe and needle assembly, and a disposal apparatus for removing, retaining and discarding needles attached to the intravenous needle device. The breakaway syringe comprises a syringe barrel which extends from a proximal barrel end to a distal barrel end. A nozzle extends distally from the distal barrel end and includes a weakened portion. Bending of the syringe barrel relative to the nozzle distal end causes the syringe to break along the weakened portion. When coupled with a needle hub and needle assembly and used with the disposal apparatus of the present invention, the syringe and attached needle assembly are held stationary within an aperture disposed on the disposal apparatus. The syringe barrel may then be moved laterally or otherwise bent relative to the needle hub to break the syringe along the weakened portion of the nozzle. The needle hub and needle assembly, now broken away from the remainder of the syringe fall freely into the disposal apparatus. A locking mechanism is provided within the aperture to prevent the removal of the needle hub and attached needle assembly once inserted within the disposal apparatus. A cove…
