Syringe Needle Patents (Class 83/944)
  • Publication number: 20130334175
    Abstract: A used needle is inserted in a housing of a needle apparatus disabling device. As the needle is pushed downwards sealing a collar opening and bears against a stationary cutter blade. The needle is pushed further into the device where it contacts upper and lower electrodes. An electric current passes through the needle, which causes it to become heated resistively to destruction. A voltage drop between the electrodes is detected by a processor activating a motor driven movable cutter blade which then severs a remaining stub or remnant of the needle portion and simultaneously urges the severed stub downwardly onto the electrodes to ensure its complete destruction. During this process any sparks or airborne contaminants, or combustion gases are prevented from escaping through the opening by the sealing action of the apparatus.

  • Patent number: 7389873
    Abstract: A device for severing syringe needles and storing the same for later disposal includes a lower box portion with a substantially flat bottom hinged to an upper lid portion, and a guillotine-like mechanism and an adjacent diaphragm spanning the two portions of an opposing side of the device. The guillotine preferably includes an angled blade in cross section such that when the needle is cut it is projected further through the diaphragm and into the device. The overall configuration and severing operation is in some ways akin to that of a stapler, in that a used syringe needle is inserted into a small gap between the two portions, and the top pushed down operating the guillotine to remove and retain the needle.

  • Patent number: 5736706
    Abstract: A method and apparatus for sterilizing and destroying a syringe needle includes a rotating needle carriage that receives a needle in a loading position. The needle carriage is rotated downwardly to a cut-off position. At the cut-off position, two opposing contact blades pinch the needle, which electrically connects the positive and negative terminals of a battery. Current flows through the contact blades and the needle, thereby melting the needle. A slight further rotation of the needle carriage causes the contact blades to shear the needle. The sheared portion of the needle then falls into a waste compartment in the bottom of the apparatus. When the syringe is removed from the needle carriage, the needle carriage rotates upwardly and returns to the loading position.
