Patents by Inventor Rao R. Ivatury

Rao R. Ivatury has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10751494
    Abstract: Ventilator associated pneumonia (VAP) may be prevented in a patient, or its occurrence reduced in a population of patients, by using an anti-VAP device or an anti-VAP material such as an anti-VAP mouthpiece that absorbs secretions. By reducing the problem of bacterial-containing secretions that otherwise build up in the airway of, and elsewhere in, the intubated patient, VAP can be prevented from occurring in intubated patients, such as patients intubated with an endotracheal tube (ETT) or a nasogastric tube. Anti-VAP mouthpieces also are useable in non-intubated patients to maintain oral hygiene.
    Type: Grant
    Filed: September 23, 2016
    Date of Patent: August 25, 2020
    Assignee: Virginia Commonwealth University

  • Patent number: 7118534
    Abstract: Central Venous Pressure (CVP) is non-invasively determined with accuracy comparable to invasive measurement techniques. To do so, curves are plotted based on non-invasively determined patient information obtained by applying a controllable variable (pressure) to a vein of interest at a non-distal point and taking certain measurements (such as pressure and volume measurements) from the patient. An example of a controllable variable is voltage applied in incremental inflation/deflation of a vascular cuff (1). A curve is plotted based on datapoints (such as a volume increase curve or a volume decline curve). Pertinent, accurate CVP and/or blood volume information is obtained from the slope of the non-invasive-based curve. Accurate CVP information is provided without the risks and disadvantages of invasive measurements.

  • Patent number: 7113814
    Abstract: In an emergency medicine patient, accurate measurement of change or lack thereof from non-shock, non-ischemic, non-inflammation, non-tissue injury, non-immune dysfunction conditions is important and is provided, as practical, real-time approaches for accurately characterizing a patient's condition, using Raman (3) and/or fluorescence (30) spectroscopy with a high degree of accuracy. Measurement times are on the order of seconds. High-accuracy measurement is achieved with Raman spectroscopy interrogation of tissue. Simultaneous interrogation by NADH fluorescence spectroscopy may he used. Measurements may be non-invasive to minimally invasive. Preclinical (ultra-early) states of shock can be detected (5), severity can be determined, effectiveness of various treatments can be determined.
