  • Publication number: 20210379525
    Abstract: A waste collection unit for collecting waste material. A reservoir is supported on a portable cart for storing a liquid on the portable cart when positioned away from a docking station. A sprinkler may be coupled to the waste container and in fluid communication with the reservoir. The sprinkler is configured to direct the liquid from the reservoir towards the waste container. The reservoir is configured to receive additional liquid from the docking station to urge the liquid from the reservoir towards the sprinkler. A prefill pump may be supported on the portable cart and in fluid communication with the waste container and operable to convey the liquid from the reservoir to the waste container. A controller may be in electronic communication with a valve assembly to control flow of the liquid from the docking station into at least one of the reservoir and a second waste container.

  • Patent number: 11130089
    Abstract: 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.

  • Publication number: 20210153849
    Abstract: A cassette for collecting a tissue sample. The cassette includes a housing configured to be removably coupled with a manifold receiver of a medical fluid collection system. The housing defines a first void space, a second void space, and an outlet opening. A catch tray is removably positionable within the first void space and includes a screen defining porous features for collecting the tissue sample. A filter element separate from the catch tray is disposed within the second void space. The housing may include a cap portion defining the first void space, and a shell portion coupled to the cap portion and defining the second void space. The cassette may be simultaneously operable in a tissue collection mode in which fluid is suctioned across the catch tray to collect the tissue sample, and a bypass mode in which the fluid is not suctioned across the catch tray.

  • Publication number: 20200061255
    Abstract: A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fining receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.

  • Patent number: 10343102
    Abstract: 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.

  • Patent number: 10105470
    Abstract: A waste collection system for collecting waste during medical/surgical procedures including a mobile container cart with a waste container. A container cart is selectively coupled to a suction cart that includes a vacuum pump. The connection of the carts results in the connection of the vacuum pump to the waste container. The vacuum pump draws a vacuum that results in waste being drawn through a suction line into the waste container. The container cart holds instruments that can be removably attached to the container cart. This facilitates the configuration of the container cart for the specific procedure for which it is necessary to draw a suction.
