The invention provides a body-worn vital sign 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) and posture (upright, supine). The monitor processes this information to minimize corruption of the vital signs and associated alarms/alerts by motion-related artifacts. It also features a graphical user interface (GUI) rendered on a touchpanel display that facilitates a number of features to simplify and improve patient monitoring and safety in both the hospital and home.

Body-worn vital sign monitor

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.

The invention features a vital sign monitor that includes: 1) a hardware control component featuring a microprocessor that operates an interactive, icon-driven GUI on an LCD; and, 2) a sensor component that connects to the control component through a shielded coaxial cable. The sensor features: 1) an optical component that generates a first signal; 2) a plurality electrical components (e.g. electrodes) that generate a second signal; and, 3) an acoustic component that generates a third signal. The microprocessor runs compiled computer code that operates: 1) the touch panel LCD; 2) a graphical user interface that includes multiple icons corresponding to different software operations; 3) a file-management system for storing and retrieving vital sign information; and 4) USB and short-range wireless systems for transferring data to and from the device to a PC.

The invention provides a monitor for measuring blood pressure and other vital signs from a patient without using a cuff. The invention provides a hand-held device for measuring vital signs (e.g. blood pressure) from a patient that features: i) a housing that encloses a first sensor, that includes a first electrode and a first optical system configured to generate a first optical signal; ii) a second sensor that includes a second electrode and a second optical system configured to generate a second optical signal; iii) an amplifier system, in electrical contact with the first and second electrodes, configured to processes electrical signals from the first and second electrodes to generate an electrical waveform; and iv) a microprocessor, in electrical communication with the amplifier system, first optical system, and second optical system, the microprocessor configured to process the electrical waveform and first and second optical signals with an algorithm to determine at least one of the patient's vital signs.

System for measuring vital signs using bilateral pulse transit time

A method and apparatus for measuring a patient's blood pressure featuring the following steps: 1) measuring a time-dependent optical waveform with an optical sensor; 2) measuring a time-dependent electrical signal with an electrical sensor; 3) estimating the patient's arterial properties using the optical waveform; 4) determining a pulse transit time (PTT) from the time-dependent electrical signal and the time-dependent optical waveform; and 5) calculating a blood pressure value using a mathematical model that includes the PTT and the patient's arterial properties.

Vital sign monitor for cufflessly measuring blood pressure using a pulse transit time corrected for vascular index

A body-worn sensor that measures respiratory rate and other vital signs using an acoustic sensor (e.g., a small-scale sensor). The body-worn sensor features a chest-worn patch sensor that combines both the acoustic sensor and an ECG electrode into a single adhesive patch. To measure blood pressure, the device additionally performs a 'composite' PTT-based measurement that features both pressure-dependent and pressure-free measurements. The acoustic sensor measures respiration rate by recording sounds related to the patient's inspiration and expiration. The acoustic sensor is typically placed near the patient's trachea, but can also be placed on the middle right and left side of the chest, and the middle right and left side of the back.

Device for determining respiratory rate and other vital signs

A method and apparatus for continuous measurement of blood pressure, based on pulse transit time, which does not require any external calibration. This technique, referred to herein as the 'composite technique', is carried out with a body-won sensor that measures blood pressure and other vital signs, and wirelessly transmits them to a remote monitor. A network of disposable sensors, typically placed on the patient's right arm and chest, connect to the body sensor and measure a time-dependent electrical waveform, optical waveform, and pressure waveform. The disposable sensors typically include an armband that features an inflatable bladder coupled to a pressure sensor, at least 3 electrical sensors (e.g. electrodes), and an optical sensor (e.g., a light source and photodiode) attached to a wrist-worn band.
