Patents by Inventor John H. CALHOON

John H. CALHOON 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).

  • Signaling unit designed to introduce vibrational impulse patterns into an intravenous fluid column
    Patent number: 11666700
    Abstract: Certain embodiments are directed to an inline device(s) for monitoring a fluid path.
    Type: Grant
    Filed: August 19, 2016
    Date of Patent: June 6, 2023
    Assignee: Board of Regents, The University of Texas System
    Inventors: Daniel T Dearmond, John H. Calhoon
  • System of intravenous fluid/medication delivery that employs signature flow amplitudes of frequencies to facilitate the detection of intravenous infiltration
    Patent number: 10842931
    Abstract: Occlusion of a vein during IV fluid treatment, in some embodiments, may be detecting by delivering predetermined flow patterns (e.g., flow frequencies and/or amplitudes) of fluid to the subject and monitoring the flow of the fluid downstream vein. A deviation of the flow pattern downstream from the vein from the predetermined flow pattern may be used to determine if an occlusion has occurred. A system for monitoring fluid delivery to a subject includes, in some embodiments, a pump system capable of delivering flow with predetermined flow rates and one or more flow detectors capable of detecting downstream peripheral venous flow.
