  • Patent number: 11638533
    Abstract: The invention provides a body-worn system that continuously measures pulse oximetry and blood pressure, along with motion, posture, and activity level, from an ambulatory patient. The system features an oximetry probe that comfortably clips to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. Analog versions of these signals pass through a low-profile cable to a wrist-worn transceiver that encloses a processing unit. Also within the wrist-worn transceiver is an accelerometer, a wireless system that sends information through a network to a remote receiver, e.g. a computer located in a central nursing station.

    Abstract: Improvements in ingestible electronics with the capacity to sense physiologic and pathophysiologic states have transformed the standard of care for patients. Yet despite advances in device development, significant risks associated with solid, non-flexible gastrointestinal transiting systems remain. Here, we disclose an ingestible, flexible piezoelectric device that senses mechanical deformation within the gastric cavity. We demonstrate the capabilities of the sensor in both in vitro and ex vivo simulated gastric models, quantified its key behaviors in the GI tract by using computational modeling, and validated its functionality in awake and ambulating swine. Our piezoelectric devices can safely sense mechanical variations and harvest mechanical energy inside the gastrointestinal tract for diagnosing and treating motility disorders and for monitoring ingestion in bariatric applications.

  • Patent number: 10813586
    Abstract: A system and method are provided for diagnosis of animal respiratory diseases using auscultation techniques. Animal lung sounds are recorded and stored as digitized data. Algorithms are applied to the data producing an output indicative of the health of the animal. Another method determines effectiveness of antibiotics administered to animals based upon observed relationships between lung score categories obtained from auscultation. A comparison is made between sample populations of animals that receive different classifications of antibiotics, and this data is compared to lung score categories observed for each of the animals that received the antibiotics. A statistical analysis is conducted to confirm statistical differences in case fatality rates between lung score categories.

  • Patent number: 10736521
    Abstract: A method of monitoring and/or diagnosing an autoregulation mechanism of blood pressure of a living being using an ECG signal includes recording the ECG signal of the living being, and the recording a pulse wave curve synchronously with the recording of the ECG signal. Heart rate intervals are determined from the ECG signal. A pulse wave transit time is determined for each heart rate interval from the pulse wave curve. A plurality of significant changes in the pulse wave transit times are determined according to a specified criterion. One respective heart rate interval correlated in time with each significant change in the pulse wave transit times is selected as an anchor point. A determined limited number of temporally successive heart rate intervals temporally before and/or after each anchor point are selected to thus generate a limited sequence of heart rate intervals for each anchor point.

  • Patent number: 10667711
    Abstract: Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. The wearable monitor can interoperate wirelessly with other physiology and activity sensors and mobile devices, and can include cellular phone capabilities. The power usage of the wireless communication can be reduced by using a low energy wireless transceiver in the monitor. The monitor detects that the monitor has been adhered to the patient and begin collecting physiological data after such detection, preserving battery power.
