Life sign detection and health state assessment system
First Claim
1. A life signs detection system for monitoring one significant vital sign and one indirect life sign of subjects, said system comprising:
- a plurality of wearable platforms, each wearable platform comprising;
a heart rate sensor configured to detect a heart rate;
a body motion sensor configured to detect motion;
a respiration rate sensor configured to determine respiration rate by detecting motion of a subject;
a temperature sensor configured to detect a temperature;
a processor comprising a rule processing engine configured to execute a health state assessment algorithm that performs a medical evaluation and determines a confidence level for the evaluation, said algorithm comprising a rule set to calculate a health state classification and a decision confidence score corresponding to an indicator of confidence; and
a transmitter configured to transmit local sensor data of medical state information detected by sensors of the wearable platform, the local sensor data of medical state information comprising heart rate, motion, respiration rate, and temperature, and configured to transmit results of the medical evaluation and the decision confidence score;
a plurality of local hubs each comprising;
an external display for displaying the results of the medical evaluation;
a local transceiver hub configured to accept connection from the external display; and
a receiver configured to receive local sensor data from said wearable platforms; and
a remote base station configured to receive information from a plurality of local hubs.

Abstract
A wearable platform embodied in a belt or patch provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. An analog circuit running an algorithm obtains the R-wave period from the EKG signal and produces electrical pulses with the period between pulses corresponding to the R-wave period. A rule based processing engine having an evaluation algorithm is capable of making a medical evaluation of subject condition and determines a confidence level for the evaluation. The rules are subject to variation depending upon the subject population. The information is communicated wirelessly to a local hub for relay to a remote monitor.
