A waste collection unit for collecting waste material. First and second waste containers are supported on a portable cart. A control panel is configured to receive one or more inputs of selectively set vacuum levels in the first and/or second waste containers. A control system controls operation of vacuum regulators based on the input(s) to regulate levels of vacuums being drawn in each of the waste containers. Pressure sensors in communication with the control system may be positioned to monitor pressure in the waste containers. A back up port support on the portable cart may be provided to receive a vacuum line for coupling a vacuum manifold to a remote vacuum source not located on the portable cart. Container lamps may be coupled to the first and/or second waste containers and configured to illuminate the waste material within the waste containers to be viewed through transparent windows.

A medical/surgical waste collection rover includes a first waste container disposed on a portable cart and receiving waste under the influence of a vacuum. A fluid measuring system includes a float element disposed within the first waste container, and a controller causing liquid in a reservoir disposed on the cart to prefill the first waste container and subject the float element to an initial lifting to a zero point level. The fluid measuring system determines a volume of contents within the first waste container based on a position of the float element relative to the zero point level. The fluid measuring system may include a sensor rod extending through the first waste container and a second waste container disposed on the cart and separated from the first waste container by a transfer valve. Methods of estimating the volume of liquid and/or medical/surgical waste within the waste container are also provided.

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.
