  • Patent number: 9707324
    Abstract: A medical waste container comprises a bag with a flexible body defining a cavity and having a fill opening. A tube has a closed end in the bag and an opposite open end projecting from the bag. An elastic ring attached to the bag around the fill opening presses against the tube. A lip projects from the tube adjacent its closed end. A tab also projects from the tube, and a discharge opening is formed in the tube between the lip and the tab. A flow path extends from the open end of the tube into the cavity when the elastic ring encircles the tube at a first position between the tab and the open end. The ring slips over the tab from the first position to a second position in which the ring covers the discharge opening as liquid passes through the flow path, adding weight to the bag.

  • Patent number: 9033943
    Abstract: A wound drainage device flow regulator for controlling fluid flow from a wound to a container. The regulator provides selective communication between a conduit and the container. The device includes a valve for communication between the conduit and the container in response to a level of vacuum in the conduit below a selected value. The valve has a diaphragm exposed to atmospheric pressure on one side and to the level of vacuum in the conduit on the other side. A force is applied to the diaphragm in opposition to atmospheric pressure. The difference between the force applied and the force generated by atmospheric pressure provides a control force required to be applied by the level of vacuum in the conduit to close the valve to interrupt communication between container and conduit. A lock mechanism locks the adjustable force mechanism at a desired adjustment corresponding to a desired level of vacuum.

  • Patent number: 8784394
    Abstract: A device for the drainage of a pleural effusion through an operatively engaged chest tube in the chest wall. The device employs a check valve situated between a vacuum source communicating with the chest tube to prevent reversal of the fluid flow out of the patient's body and possible contamination. A valve mounted on a vacuum bottle provides user control of communication of negative pressure from the vacuum bottle to the chest tube. Opening the valve on the bottle communicates negative pressure to the chest tube relative to the pressure in the tube thereby initiating a fluid flow out of the tube and the patient. Once the valve on the bottle is closed, fluid flow ceases and the check valve prevents reversal of the flow.

  • Patent number: 8366692
    Abstract: Disclosed herein are systems and methods for providing reduced or negative pressure, and more particularly cyclical reduced pressure, to treat a wound. The system can include a wound dressing, a fluid collection container, a suction source, filters, and conduits. In addition, the system can include a control device and sensors. The sensors may be configured to monitor certain physiological conditions of a patient such as temperature, pressure, blood flow, blood oxygen saturation, pulse, cardiac cycle, and the like. Application of cyclical reduced pressure between two or more values below atmospheric pressure may be synchronized with the physiological conditions monitored by the sensors. Certain embodiments of the system utilize an air reservoir and one or more valves and pressure sensors or gauges to allow for rapid cycling of the level of reduced pressure within the wound dressing between two or more reduced pressure values.

  • Patent number: 8152786
    Abstract: A catheter for collecting fluid such as blood from a vessel such as a coronary sinus of a patient has an elongated, flexible tubular portion and an annular sealing member spaced from a distal end of the tubular member. A proximal end of the tubular member is adapted to be connected to a source of suction for applying suction to a collection lumen of the tubular member. The distal end is placed in a blood vessel with the sealing member spaced from opposing surface of the vessel in an absence of a suction applied to the collection lumen. Suction is applied to the collection lumen in an amount sufficient to draw blood from the vessel through the fluid inlet and into the collection lumen and further sufficient to urge the opposing surface of the vessel to migrate into sealing engagement with the sealing member.

  • Publication number: 20110257614
    Abstract: An apparatus and method to suppress vacuum surges in a surgical aspiration system is disclosed and claimed. A vacuum surge suppressor includes a first fluid path for coupling to a surgical instrument, and a filter attached to the first fluid path. A flow restrictor is coupled to the filter with the filter disposed upstream of the flow restrictor. The filter defines a filter longitudinal axis that may be oriented vertically with respect to gravity, so that a downstream direction at the filter is upwards. The vacuum surge suppressor also includes a second fluid path for coupling to a vacuum pump. The second fluid path is connected to the flow restrictor and disposed downstream of the flow restrictor. A third fluid path is coupled to the filter and is connected to the second fluid path, bypassing the flow restrictor. A valve in the third fluid path selectively obstructs or permits flow in the third fluid path.

  • Patent number: 8002758
    Abstract: When a patient is fitted with an external gastrostomy connection to the stomach, ingested food can be removed through the gastrostomy connection using a pump-based or siphon-based system to achieve weight loss. The process of removing ingested food can be improved by alternating the infusion of liquid into the stomach with the removal of material from the stomach. Optionally, stomach acid may be captured and returned to the stomach. Optionally, nutritional supplements or medicines may be added to the infused liquid. Optionally, a flush mount connectorized system with a built in valve may be used to simplify the interface with the gastrostomy hardware that remains installed in the patient. Optionally, the system may be configured to disable itself from further use after a triggering event (e.g., the passage of time or a predetermined number of uses) has occurred.
