  • METHOD FOR MONITORING LUNG INTEGRITY
    Publication number: 20210236018
    Abstract: The present invention relates to systems and methods for monitoring impedance from a sensor in the chest of a subject to determine the status of lung inflation or presence of pneumothorax in the subject, the presence of pulmonary edema, the status of regional lung ventilation, and the status of cardiac contractility.

  • 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.

  • Protective matrix for intracorporeal biosensors that improves gastrointestinal leak detection, detects air leaks after lung surgery, and measures cardiac output after heart surgery
    Patent number: 9955896
    Abstract: The system and method may measure and monitor physiological changes in a body. In some embodiments, the system and method may measure the impedance at a site in the body. In some embodiments, the system and method identify, quantify, and localize leaks from a site following surgery, measure cardiac contractility, or lung compliance. In an embodiment, the system includes a measuring device with one or more sensors embedded in a porous matrix. Changes in the electrical properties of one or more sensors may be used to determine the presence of leaks from a site following surgery, measure cardiac contractility, or lung compliance, depending on the position of the device.

  • Intracorporeal impedance and leak monitoring device
    Patent number: 7899508
    Abstract: The system and method may measure and monitor physiological changes in a body. In some embodiments, the system and method may measure the impedance at a site in the body. In some embodiments, the system and method identify, quantify, and localize leaks from a site following surgery. In an embodiment, the system includes a flexible conduit with one or more sensors. A flexible conduit shape may be selected to facilitate monitoring of physiological changes in a body and/or detection of leaks at a desired site. In an embodiment, contrast solution may be ingested by, injected in, and/or delivered to a patient. If a leak is present at a site, salt contrast solution may leak from a site and be detected by sensors in a flexible conduit.
