Dec 7, 2004
Appl. No.:

10/904971
Inventors:

Matthew John Banet - Del Mar CA, US
Brett George Morris - San Diego CA, US
Henk Visser - San Diego CA, US
Assignee:

Triage Wireless, Inc. - San Diego CA
International Classification:

A61B 5/00
US Classification:

600485, 600500
Abstract:

The invention provides a system for measuring blood pressure from a patient that includes: 1) an optical module configured to be worn on the patient's ear and comprising at least one optical source and a photodetector; 2) a calibration source configured to make a blood pressure measurement; and, 3) a processing module configured to: i) receive a first signal from the optical module; ii) receive a second signal from the calibration source; iii) process the first and second signals to generate a calibration table; and iv) receive a third signal from the optical module and compare it to the calibration table to determine the patient's blood pressure.

US Patent:

8321004, Nov 27, 2012
Filed:

Sep 15, 2009
Appl. No.:

12/560077
Inventors:

Jim Moon - Portland OR, US
Henk Visser - San Diego CA, US
Robert Hunt - Vista CA, US
Assignee:

Sotera Wireless, Inc. - San Diego CA
International Classification:

A61B 5/02
US Classification:

600513, 600509
Abstract:

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.
