  • Publication number: 20150105740
    Abstract: A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.

  • Patent number: 8915897
    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 includes at least one fitting through which waste is drawn into the manifold. The fitting opens through an inlet port into a void space internal to the manifold. A backflow prevention valve is disposed in the manifold void space. The backflow prevention valve includes a static hub to which 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: 20140338529
    Abstract: A smoke evacuator that draws smoke generated during a medical surgical procedure away from the site at which the smoke is generated. The smoke evacuator includes a pump that draws air into a filter. A sensor internal to the filter monitors the smoke in the air stream drawn through the filter. Normally the pump runs at a low speed, a speed sufficient to draw some air in the filter. When the sensor detects the presence of an appreciable amount of smoke in the air stream the sensor sends a signal indicating the air stream is in this state to the pump controller. The controller then increases the pump speed to result in a like increase in the volume of air drawn through the smoke evacuator. Since the sensor is contained in the filter, a new sensor is installed in the system each time a new filter is installed.

  • Publication number: 20140323914
    Abstract: A cassette (2600) for use with a medical waste collection system (30). The cassette includes a housing (2602, 2612) shaped to be removably attached to a receptacle (1699) integral with the housing. A sleeve (2640) is attached to the cassette so as to be located forward of the housing. The sleeve is formed with a void space. A fitting (2664) for collection to a suction line is attached to the sleeve. A screen (2714) is removably fitted in the sleeve void space. The screen is fitted in the sleeve void space when it is desirable to catch tissue that may be entrained in the fluid stream from the suction line.

  • 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: 20050187529
    Abstract: A waste collection unit is provided for collecting medical waste such as bodily fluids and materials from a patient, and disposing of the medical waste at a docking station. The waste collection unit comprises a canister for containing the medical waste and a carrier with wheels for transporting the waste collection unit between use areas, such as operating rooms, and the docking station. A vacuum housing with a plurality of vacuum ports is provided for connecting to an external vacuum source to draw a vacuum inside of the canister and collect the medical waste from the patient. The waste collection unit also includes a sprinkler system for cleaning the canister after disposing of the collected medical waste. The sprinkler system includes a sprinkler having a helical configuration in a cap of the canister for generating a cone-shaped spray pattern and a spray nozzle in a base of the canister.

  • Publication number: 20050171495
    Abstract: A waste collection unit is provided for collecting medical waste from a surgical site. The waste collection unit comprises a canister for collecting the medical waste. A disposable manifold is coupled to the canister to filter solid and semi-solid debris from the medical waste prior to the medical waste entering the canister. A manifold interface assembly of the waste collection unit provides a valve assembly having a valve body and flapper door to prevent the escape of the medical waste from the canister when the manifold is removed from the canister. The manifold interface assembly is configured such that the flapper door is engaged by the manifold upon insertion of the manifold into the canister. In particular, the manifold includes a stem that is sized for inserting into an inlet port of the canister and the stem has a length sufficiently long to engage and open the flapper door upon insertion.
