  • Recycling apparatus by crushing and pasteurizing used hypodermic syringes and compressing waste
    Patent number: 6568614
    Abstract: A recycling apparatus comprises a body; a slit on top having a hole on one end; a rear internal pasteurizing mechanism comprising a pulverizing device and a bottom first container; a front internal crushing mechanism comprising two sets of parallel blade wheels and a bottom second container; and a waste storage mechanism comprising a third container, a spring-loaded lever, and a plunger sliding in the third container. In use sequentially insert the needles of the used syringes into the slit with the piston syringe portion of the syringe held on the slit, push the syringes forward to cause the needles to contact the pulverizing device to be ground into powder while being pasteurized, the powder are dropped into the first container, the remained piston syringe portion of each syringe eventually drops into the crushing mechanism through the hole, the dropped piston syringe portion of each syringe is pressed and cut into pieces by the sets of the blade wheels, and the pieces are dropped into the second container.
