Appl. No.:

7/471374

Inventors:

David B. Mennel - Greenwood IN
Joseph H. Wilson - Speedway IN
Martin E. Elliott - Indianapolis IN
Gary D. Gann - Greenwood IN

Assignee:

Medical SafeTEC, Inc. - Indianapolis IN

International Classification:

B02C 1922
B01D 3600

US Classification:

241 34

Abstract:

A medical waste disposal system is provided for disposing of biologically contaminated waste material situated inside a rigid, form-stable container. The disposal system includes a processing unit for shredding the waste material into a shredded mass and for transporting the shredded mass into a disintegrator. The disintegrator mixes the shredded mass with a liquid disinfectant solution to disinfect the shredded mass and disintegrates the shredded mass into an unrecognizable particulate waste material.

Abstract:

A waste disposal system for treating and disposing of infectious waste articles in a substantially controlled, closed, aseptic environment and for converting such infectious waste articles into a safely disposable, non-infectious non-toxic residue of solid waste independent from disinfecting liquid waste. A waste delivery conveyor transfers waste articles from an input region to preliminary waste processing apparata for preliminarily fragmenting the waste for further treatment by the system. Disinfectant spray is deposited on the waste as it enters the preliminary waste processing apparatus with the fragments resulting therefrom, together with the disinfectant liquid, being transferred to rotary hammermill elements to convert the fragment disinfectant solution to a solution of fine waste particles and disinfectant solution. Liquid solid particle separator apparata then separates the solid waste particles from the liquid disinfectant for independent evacuation of same. The system further includes vacuum ventilation elements to maintain any released bacteria or particles within the system until completely processed and disinfected with system switching controls serving to operate and sequence operation of the system components relative to one another by computer.
