Portable, multi-channel, physiological data monitoring system
First Claim
1. A data monitoring system for gathering physiological data from a subject, the system comprising(a) a portable sensing unit comprising(i) a first plurality of sensors, each of the sensors of the first plurality being adapted for attachment to the subject for monitoring the value of a physiological parameter of the subject and for generating a signal corresponding to that value;
- (ii) a multiplexer which receives the analog signals from the first plurality of sensors and sequentially forwards the analog signals to an analog-to-digital converter;
(iii) an analog-to-digital converter which receives the sequentially forwarded analog signals from the multiplexer as an input signal and converts the input signal to a corresponding first binary data word which is provided in parallel to a serial encoder;
(iv) a second plurality of sensors, each of the sensors of the second plurality being adapted for attachment to the subject for monitoring the value of a physiological parameter of the subject and for generating an electrical signal corresponding to that value;
(v) means for converting the electrical signals generated by the second plurality of sensors into a corresponding second binary data word which is provided in parallel to the serial encoder;
(vi) a serial encoder which receives the first and second binary data words and converts them to a serial digital data stream; and
(vii) a digital telemetry transmitter which receives the serial digital data stream and transmits the serial digital data stream by low-power radio signals; and
(b) a base station comprising(i) a receiver which receives the radio signal and reconverts it to a digital data signal; and
(ii) a data processing unit which receives the reconverted digital data signal for storage and/or analysis and review.

Abstract
A data monitoring system which simultaneously monitors, transmits by radio an records data relating to a plurality of physiological parameters comprises a portable sensor unit which is worn by the patient and includes a plurality of sensors attached to the patient'"'"'s body each of which monitors a physiological parameter and generates a corresponding electrical signal, a circuit pack which converts the signals into a series stream of digital data and a transmitter which periodically transmits the data. A base station includes both a receiver which receives the transmitted data and reconverts it to a digital signal and a data processing unit which records the data.
