  • Publication number: 20100036335
    Abstract: A removable manifold for a medical/surgical waste collection system. The manifold is dimensioned to be mounted to a receiver integral with the system. The manifold includes a driver for engaging a complementary valve internal to the receiver. The valve regulates flow between the receiver and the down line components of the waste collection system. The valve is normally closed. When the manifold is fitted to the receiver the driver engages the valve so as move the valve to the open position. This allows fluid flow from the manifold and receiver to the downstream components of the system.

  • Publication number: 20080053539
    Abstract: A manifold assembly (100) for directing and filtering material (102) from fluid flowing into a medical waste collection device (104) includes a plurality of inlet ports (116) and an outlet port (118) with a filter (108, 110, 112) disposed between the ports (116, 118) along a fluid path (120). An outlet check-valve (114) is disposed at the outlet port (118) for opening in response to a predetermined vacuum pressure applied to the outlet port (118) from the medical waste collection device (104).

  • Publication number: 20070135779
    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.

  • Publication number: 20050189288
    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.
