Liquid Filling By Evacuating Container Patents (Class 137/205)
  • Patent number: 9408954
    Abstract: Methods and apparatuses for detecting full waste canister and/or fluid flow path blockage conditions are disclosed. Also disclosed are methods and apparatuses for controlling a pump. In some embodiments, flow of fluid can be restricted in a portion of the fluid flow path. A controller can be configured to compare a difference in pressure values upstream and downstream of a fluid flow restrictor to a pressure difference threshold, and determine based on the comparison whether to activate an alarm indicating the full waste canister condition or the fluid flow path blockage condition. The controller can be additionally or alternatively configured to determine a fluid flow using a flow meter, open a selectable valve in response to a comparison of the fluid flow with a fluid flow threshold, determine fluid flow after opening the valve, and determine based on the fluid flow after opening the valve whether to activate the alarm.

The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber.

  • Patent number: 7681607
    Abstract: The present invention is a pump control and distribution system consisting of a pump and reversing flow control valve with a single-handle to control flow direction and flow rate of a liquid. The system can be operated at a rate of 0 to 300 gallons per minute and the flow reversed or stopped with a single motion of the operating handle. The flow rate of the liquid can be precisely controlled in either direction, along with the liquid pressure. This allows the use of a constant speed pump turning in one direction and gives the operator the ability to control the product transfer regardless of viscosity or volume. A purge valve connected to the outlet of the pump is used to remove substantially all retained liquid in the system after transfer of liquid is complete. The system can be mounted to a vehicle for delivery of bulk liquids.

    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: 7506673
    Abstract: The present invention is directed to a manual bulk liquid pump control and distribution system that utilizes a single-handle manual operation for direction of flow and speed, along with providing a neutral position for standby. The system can be operated at a rate of 0 to 250 gallons per minute and be reversed with a single motion of the operating handle. The pump operates in one direction at a fixed RPM, resulting in longer pump life and safer operation. For added safety, the system utilizes the pump's relief valve for both discharge and suction operation. It has the ability of sucking the liquid out of the lines and hoses after each transfer operation. This system has an aluminum flow-reversing valve or two-way valve at the center of the design. This valve allows the flow of the product to be precisely controlled in either direction, along with the flow rate and pressure. This gives the operator the ability to control the product regardless of viscosity or volume.

  • Patent number: 7506659
    Abstract: A system operating in an environment under a vacuum draw in which liquid accumulates utilizes the weight of the liquid to discharge the liquid from the system. The system includes a first holding tank and a second holding tank interconnected by a liquid passageway and a pressure equalization passageway. A number of valves are provided for controlling flow into and out of the second holding tank. The valves are operated in a sequence to use gravity to bring accumulating liquid from the first holding tank to the second holding tank in the vacuum environment, and then to discharge the liquid from the second holding tank to the environment outside of the system.

  • Publication number: 20080203001
    Abstract: A check valve (10) comprises, a flexible tube (11) having first and second end portions defining an inlet (13) and an outlet (14), respectively, and a rigid valve body (12) surrounding the flexible tube (11). The end portions of the flexible tube are sealingly fixed to the valve body (12) to define an enclosed space (17) between the exterior of the flexible tube and the interior of the valve body. A fixed volume of a substantially incompressible fluid is located in the enclosed space (17). When the pressure at the outlet (14) is greater than the pressure at the inlet (13), the flexible tube is substantially collapsed so as to close the valve or allow severely restricted flow. However when the pressure at the inlet is greater than that at the outlet, some of the fluid is displaced from the inlet area towards the outlet area so that the flexible tube (11) is expanded in the area adjacent the inlet and the tube is substantially open.

  • Patent number: 7357142
    Abstract: An apparatus for continuously aspirating a fluid from a fluid source. A vacuum source is operatively connected to a first container forming a first chamber and a second container forming a second chamber. A fluid collection tube provides communication between the fluid source and each of the first chamber and the second chamber. A first level sensor is positioned within the first chamber and a second level sensor is positioned within the second chamber. Upon receiving a signal generated by one of the first level sensor and the second level sensor, a relay responsively exposes a vacuum within one of the first chamber and the second chamber to continuously aspirate at least a portion of the fluid from the fluid source. A shut-off valve is preferably positioned within each of the first chamber and the second chamber to prevent communication between the vacuum source and the corresponding chamber with a fluid level within the chamber at a fluid level setpoint.

  • Patent number: 7152618
    Abstract: A vacuum station is used for storing sewage from a vacuum sewage pipe and then delivering the sewage to a sewage treatment plant or the like. The vacuum station includes a collection tank for collecting sewage, a plurality of vacuum pumps for depressurizing and pressurizing an interior of the collection tank, and a controller for controlling the plurality of vacuum pumps. The controller controls at least one of the vacuum pumps so as to rotate in normal direction so that the interior of the collection tank is depressurized to collect sewage into the collection tank, and at least one of the vacuum pumps so as to rotate in reverse direction when the sewage in the collection tank reaches a predetermined sewage level so that the interior of the collection tank is pressurized to discharge the sewage from the collection tank.

  • Patent number: 7124769
    Abstract: A system and method for servicing restrooms on the upper floors of a high rise building. The system is comprised of sections of hoses that are interconnected by valves, each valve configured to provide a user with the ability to selectively shut off the flow of material in a vertical or horizontal direction. These vacuum hoses are then connected to a liquid cooled pump, which is connected to a vacuum tank. The system operates by selectively opening and closing the vertical and horizontal valves to focus vacuum force in areas to be cleaned and prevent vacuum in non-desired areas.
