Wearable Apparatus, System and Method for Detection of Cardiac Arrest and Alerting Emergency Response

摘要

The disclosure provides a wearable cardiac arrest detection and alerting device that incorporates a non-invasive sensor based on optical and/or electrical signals transmitted into and received from human tissue containing blood vessels, and that transcutaneously quantifies the wearer's heart rate. The heart-rate quantification enables the detection of the absence of any heart beat by the wearable detection and alerting device indicative of the occurrence of a cardiac arrest, wherein the heart is no longer achieving effective blood circulation in the individual wearing the device. The display on the wearable cardiac arrest detection and alerting device may include the elapsed time since the time of detection of a heart rate that is below a predetermine lower limit value, i.e., the detected occurrence of a cardiac arrest event.

主权项

1. A wearable device for measuring one or more of heart rate or blood pressure of an individual whose skin is in contact with the wearable device and for communicating a cardiac arrest event, comprising:
[a] a first photon source having a wavelength in the range from 600 nm to 760 nm and directed at skin in contact therewith; [b] a second photon source having a wavelength is in the range from 800 nm to 950 nm and directed at skin in contact therewith; [c] one or more electro-optical photodetectors to receive photons from the skin that received photons from the first and second photon sources; [d] a battery; [e] a terminal assembly to enable charging of the battery; [f] electrical components and an algorithm for converting the received photons into a measured of a wearer of the wearable device; [g] digital memory to store a lower limit value of one or more of heart rate or blood pressure and identification indicia for the wearable device; [h] an audible alarm to alert that the measured one or more of heart rate or blood pressure is less than the heart rate lower limit value; [i] a global positioning satellite (GPS) receiver; and [j] a wireless transmitter for transmitting to others:
[i] the identification indicia of the wearable device,[ii] the GPS derived latitude and longitude coordinates of the wearable device, and[iii] an alert that that the measured one or more of heart rate or blood pressure is less than the heart rate lower limit value indicative of a cardiac arrest event.
