Abstract

A waste collection and disposal system for use in health care facilities is provided. The system includes a mobile waste collection unit for moving between use areas in the health care facility to collect waste material generated during medical procedures including body fluids, body tissues, saline, etc. The waste collection unit includes stacked upper and lower waste containers for receiving the waste material. During use, the upper waste container can be emptied into the lower waste container for temporary storage. In addition, different vacuum levels can be provided in the waste containers during complex procedures. Once a user desires to empty the waste collection unit, the waste collection unit is wheeled to a docking station. At the docking station, the waste material is off-loaded to a waste drain and the waste collection unit is cleaned and rinsed for further use.
