A method and apparatus for the treatment of contaminated medical waste, including solid and non-solid, potentially infectious materials, permits the collection of such medical waste at the point and at the time of its generation in a solid container, which is subsequently transported for pulverization, disinfection and safe disposal. A separate portable processing chamber, with an integral means to treat medical waste, is used at locations remote from its power unit for the collection of medical waste and then moved to the location of the power unit to drive the waste-treatment means within the chamber. The separate waste collection and treatment assembly includes a closable chamber, a rotating waste treatment system that is rotatably carried within the chamber by bearings spaced on a supporting cylinder carried by the chamber bottom, a plurality of pivotable blades that are carried by a rotating system and have a configuration which, in cooperation with surfaces of the chamber walls, provide effective disintegration, pulverization and blunting of solid waste and cutting and mincing of non-solid waste, and the circulation and disinfection of the medical waste within the separate chamber.
A method of treatment of medical waste material comprising the steps of:
A method of treating solid and soft medical waste, comprising:
A medical waste treatment system, comprising:
In a medical waste treatment apparatus comprising a closeable chamber, including a bottom, a sidewall and a top, for the collection and treatment of solid and soft medical waste, and a plurality of waste treating blades pivotally mounted on a rotatable hub to rotate within said closeable chamber adjacent its bottom, the improvement comprising a plurality of rigid fenders fixed to the rotatable hub, each of said plurality of rigid fenders being carried adjacent the pivotal mounting of one of said plurality of waste treating blades and extending downwardly from said rotatable hub to a small clearance space above the chamber bottom.
Apparatus for the treatment of used hypodermic needles, comprising:
In a medical waste treatment apparatus comprising a closeable chamber including a bottom, a sidewall and a top that forms a closeable chamber opening, and a rotating waste treatment assembly within said chamber for destruction and disinfection of medical waste, and a closure for said chamber opening, the improvement wherein said closure comprises:
In a medical waste treatment apparatus comprising a portable closeable chamber including a bottom, a sidewall and a top forming a closeable opening, a rotating waste treatment system comprising a plurality of pivotable blades, and an abutment bar and sidewall providing an abutment surface and cutting edge, said blades and abutment bar cooperating to destroy medical waste placed in the chamber, the improvement comprising:
In a medical waste treatment apparatus comprising means forming a chamber to receive and treat solid and soft medical waste, a rotating waste treatment assembly within said chamber, a motor to drive the rotating waste treatment assembly, and a walled enclosure for said chamber forming means and said driving motor including a plurality of sidewalls and an openable top to permit access to said chamber forming means, wherein said chamber forming means is separable from said medical waste treatment apparatus, with a plurality of feet on its bottom, and wherein said walled enclosure supports said separable chamber forming means and driving motor, the further improvement wherein a support plate carries a chamber receiving plate supporting said separable chamber and having a plurality of openings adapted to receive the feet of said separable chamber and further carries said driving motor for the rotating waste treatment assembly, said chamber-receiving plate and support plate having openings permitting mechanical interconnection of the driving motor and rotating waste treatment assembly, said support plate being carried on vibration isolating supports by a plurality of isolation bars, said plurality of isolation bars being carried by said walled enclosure.
Apparatus for the treatment of used hypodermic needles, comprising:
An apparatus for the disintegration and disinfection of medical waste, comprising:
