  • Patent number: 8088291
    Abstract: A method of collecting medical waste in a waste collection unit using a disposable manifold and filter assembly. The disposable manifold and filter assembly includes a manifold housing with a plurality of inlets, a neck extending from the manifold housing to define an outlet, and a filter basket disposed in the manifold housing. The method includes inserting the neck into the waste collection unit to direct the medical waste passing through the disposable manifold and filter assembly into the waste collection unit. Tubes are connected to the inlets of the manifold housing to provide a path for the medical waste to travel from a target site, e.g., a patient, to the manifold housing. A vacuum is drawn in the waste collection unit to pull the medical waste through the tubes and into the disposable manifold and filter assembly where the medical waste is processed/filtered in a plurality of stages.

  • Publication number: 20100049152
    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.

  • Patent number: 7497340
    Abstract: A manifold and filter assembly for use with a waste collection unit is provided. The manifold and filter assembly directs and filters medical waste flowing into the waste collection unit. The manifold and filter assembly comprises a manifold body defining a chamber and an outlet for directing the medical waste into the waste collection unit. A manifold cap is fitted to the manifold body to close the chamber. The manifold cap defines a plurality of inlets for receiving the medical waste. A filter basket having a bottom and a peripheral wall defining a plurality of openings is snap-locked to the manifold body. The filter basket is positioned such that a fluid bypass is formed between the filter basket and the manifold body and between the filter basket and the manifold cap. The fluid bypass is in fluid communication with the outlet whereby the medical waste can flow over the peripheral wall to the outlet through the fluid bypass.
