Patent number: 11963746Abstract: The invention provides a body-worn monitor featuring a processing system that receives a digital data stream from an ECG system. A cable houses the ECG system at one terminal end, and plugs into the processing system, which is worn on the patient's wrist like a conventional wristwatch. The ECG system features: i) a connecting portion connected to multiple electrodes worn by the patient; ii) a differential amplifier that receives electrical signals from each electrode and process them to generate an analog ECG waveform; iii) an analog-to-digital converter that converts the analog ECG waveform into a digital ECG waveform; and iv) a transceiver that transmits a digital data stream representing the digital ECG waveform (or information calculated from the waveform) through the cable and to the processing system. Different ECG systems, typically featuring three, five, or twelve electrodes, can be interchanged with one another.Type: GrantFiled: August 23, 2021Date of Patent: April 23, 2024Assignee: SOTERA WIRELESS, INC.Inventors: Jim Moon, Henk Visser, II, Robert Kenneth Hunt, Devin McCombie, Marshal Singh Dhillon, Matthew J.

Patent number: 11918321Abstract: The invention provides a body-worn monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling). The body-worn monitor processes this information to minimize corruption of the vital signs by motion-related artifacts. A software framework generates alarms/alerts based on threshold values that are either preset or determined in real time. The framework additionally includes a series of ‘heuristic’ rules that take the patient's activity state and motion into account, and process the vital signs accordingly. These rules, for example, indicate that a walking patient is likely breathing and has a regular heart rate, even if their motion-corrupted vital signs suggest otherwise.Type: GrantFiled: April 26, 2021Date of Patent: March 5, 2024Assignee: SOTERA WIRELESS, INC.Inventors: Devin McCombie, Matt Banet, Marshal Dhillon, Jim Moon

Patent number: 11896350Abstract: A system and method for measuring vital signs and motion from a patient comprising a plurality of sensors, each comprising a processor and analog-to-digital converter configured to generate the physiologic data waveform(s) from the sensor as synchronized, separately resolvable digital data comprising a header indicating the sensor from which the digital data originates, and to transmit the physiologic data waveform(s) to a processing system via a cable comprising a terminal connector that reversibly mates with one of a plurality functionally equivalent of connectors to operably connect the sensor to the processing system. The processing system receive sthe physiologic data waveforms and determines therefrom one or more vital signs for the individual, which are transmitted to a remote vital sign monitor.Type: GrantFiled: June 17, 2019Date of Patent: February 13, 2024Assignee: SOTERA WIRELESS, INC.Inventors: Jim Moon, Devin McCombie, Marshal Dhillon, Matthew Banet

Publication number: 20230284911Abstract: The invention provides methods and systems for continuous noninvasive measurement of vital signs such as blood pressure (cNIBP) based on pulse arrival time (PAT). The invention uses a body-worn monitor that recursively determines an estimated PEP for use in correcting PAT measurements by detecting low frequency vibrations created during a cardiac cycle, and a state estimator algorithm to identify signals indicative of aortic valve opening in those measured vibrations.Type: ApplicationFiled: May 15, 2023Publication date: September 14, 2023Applicant: SOTERA WIRELESS, INC.Inventors: Devin McCOMBIE, Guanqun ZHANG, Isaac HENRY

Publication number: 20230225633Abstract: 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.Type: ApplicationFiled: March 20, 2023Publication date: July 20, 2023Applicant: SOTERA WIRELESS, INC.Inventors: Jim Moon, Devin McCombie, Matt Banet, Marshal Dhillon

Publication number: 20230200663Abstract: The invention provides a system and method for measuring vital signs and motion from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient.

Patent number: 11330988Abstract: The present invention provides a technique for continuous measurement of blood pressure based on pulse transit time and which does not require any external calibration. This technique, referred to herein as the ‘Composite Method’, is carried out with a body-worn monitor that measures blood pressure and other vital signs, and wirelessly transmits them to a remote monitor. A network of body-worn sensors, typically placed on the patient's right arm and chest, connect to the body-worn monitor and measure time-dependent ECG, PPG, accelerometer, and pressure waveforms. The disposable sensors can include a cuff that features an inflatable bladder coupled to a pressure sensor, three or more electrical sensors (e.g. electrodes), three or more accelerometers, a temperature sensor, and an optical sensor (e.g., a light source and photodiode) attached to the patient's thumb.Type: GrantFiled: July 1, 2019Date of Patent: May 17, 2022Inventors: Matthew Banet, Marshal Dhillon, Devin McCombie
