  • Patent number: 10646648
    Abstract: An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

  • Patent number: 8950728
    Abstract: A device and method to constrict or occlude the lumen of a flexible tube may include an occluder under the influence of an elastic force, such as a spring force, that can compress a portion of the wall of the flexible tube. The occluder can be under the influence of the elastic force, but prevented from occluding the tube by a stop. The stop can be connected to a tube gripping feature, so that a pulling force on the tube near the gripping feature can disengage the stop from the occluder, releasing the occluder to compress the tube. In some embodiments, the pulling force applied to the tube causes movement of the gripping feature by taking up slack in a portion of the tube held in the device. In other embodiments, the pulling force applied to the tube causes the tube to stretch elastically near the gripping feature, causing the gripping feature to move, and disengaging the stop from the occluder.

    Abstract: A variable hemostasis valve is disclosed that may be used during medical procedures to prevent blood loss while permitting the percutaneous introduction, operation, and removal of medical instruments. A flexible tubular seal element is disclosed that is disposed within the variable hemostasis valve to provide a fluid-tight, adjustable seal. After insertion of a medical instrument into the valve through at least a portion of the flexible tubular seal element, a proximal portion of the valve housing may be rotated to cause the tension of the flexible tubular seal element to increase over the inserted medical instrument and engage the valve in a closed position. The proximal portion of the valve housing may then be rotated in an opposite direction to release the seal and return the tubular seal element to a relaxed lumen open position.

  • Publication number: 20140107611
    Abstract: A valve apparatus for a medical injection system includes a pinching member and at least one spring-loaded anvil. A tubing line of the injection system may be positioned between the pinching member and the anvil, such that when the pinching member is moved into a pinching position adjacent to the anvil, for example, by rotation of a shaft to which the member is coupled, the pinching member compresses the tubing line against the spring-loaded anvil. The pinching member is preferably rotatable about an auxiliary axis, which is eccentric, or offset from a central axis of the shaft. A spring member of the spring-loaded anvil is preferably pre-loaded. In certain applications, the pinching member, when moved into the pinching position, applies a pinching force of greater than approximately 45 pounds, for example, to prevent flow through the tubing line at an injection pressure of up to approximately 1200 psi.
