System and methods for conversion of biohazard to municipal waste

Abstract

A system for shredding medical waste, the system comprising a medical waste treating chamber (4) being an interior of an enclosure disposed within an environment which is not to be polluted, a motor (11a), a shredder (2) seated in the chamber and including a motor-driven shaft (17) and blades rotated by the shaft, the shaft (17) extending through the enclosure thereby to define an interface between the waste treating chamber (4) and the environment, and interface seal apparatus (101) preventing leakage of at least fluids from the medical waste treating chamber into the environment, via the interface.

AI Technical Summary

Benefits of technology

The present invention is about a system that uses both vacuum and pressure to treat medical waste in a sterilizer. This system effectively removes air from the chamber, replacing it with steam, which helps to enhance sterilization.

Problems solved by technology

Hospitals and other facilities generate large amounts of medical waste daily.

Existing techniques for treatment of medical waste are so unsatisfactory that some health facilities in first-world countries elect to convey only partially neutralized medical waste to poorly regulated third-world countries for disposal, thereby causing dangerous planet-wide pollution.

Existing medical waste treating systems are characterized by one or more of the following: large size necessitating a facility located at a distance from the hospital or other waste-generating facility rather than within the hospital; failure to achieve adequate de-contamination; generation of large volumes of waste which are costly to dispose of due to high per-volume disposal costs; generation of a strong, unpleasant odor; requirement for distasteful manual handling e.g. to empty the system's chamber of processed waste which did not exit automatically.
