Patent number: 8180440Abstract: 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: May 20, 2009Date of Patent: May 15, 2012Assignee: Sotera Wireless, Inc.Inventors: Devin McCombie, Marshal Dhillon, Matt Banet, Jim Moon

BODY-WORN SENSOR FEATURING A LOW-POWER PROCESSOR AND MULTI-SENSOR ARRAY FOR MEASURING BLOOD PRESSURE
Publication number: 20120108983Abstract: A system is described that continuously measures a patient's blood pressure over a length of time. The system features a sensor assembly featuring a flexible cable configured to wrap around a portion of a patient's arm. The flexible cable features a back surface that includes at least two electrodes that are positioned to contact the patient's skin to generate electrical signals. It additionally features an optical sensor that includes at least one light source and at least one photodetector. These components form an optical sensor that is configured to generate an optical signal by detecting optical radiation emitted by the at least one light source and reflected from a blood vessel underneath the patient's skin.Type: ApplicationFiled: January 9, 2012Publication date: May 3, 2012Applicant: Sotera Wireless, Inc.Inventors: Matthew J. Banet, Zhou Zhou, Kenneth Robert Hunt, Henk Visser, II -

Publication number: 20110257553Abstract: The invention provides a system for measuring respiratory rate (RR) from a patient. The system includes an impedance pneumography (IP) sensor, connected to at least two electrodes, and a processing system that receives and processes signals from the electrodes to measure an IP signal. A motion sensor (e.g. an accelerometer) measures at least one motion signal (e.g. an ACC waveform) describing movement of a portion of the patient's body to which it is attached. The processing system receives the IP and motion signals, and processes them to determine, respectfully, frequency-domain IP and motion spectra. Both spectra are then collectively processed to remove motion components from the IP spectrum and determine RR. For example, during the processing, an algorithm determines motion frequency components from the frequency-domain motion spectrum, and then using a digital filter removes these, or parameters calculated therefrom, from the IP spectrum.Type: ApplicationFiled: April 19, 2010Publication date: October 20, 2011Applicant: SOTERA WIRELESS, INC.Inventors: Matt BANET, Marshal DHILLON, Devin McCOMBIE
