Remote ECG monitoring system
First Claim
1. A remote monitoring and telemetry system for use in a facility equipped with a master antenna television cable comprising:
- means operatively coupled to a patient for deriving baseband information therefrom and for transmitting a first frequency signal modulated with said baseband information;
means mounted in said facility in proximity to said patient for receiving said first modulated signal and for coupling to said master antenna television cable a second signal having a second frequency different from said first frequency and modulated with said baseband information;
means coupled to said master antenna television cable adjacent the head end thereof for receiving said second modulated signal and for coupling to said master antenna television cable an amplified signal having a third frequency different from said first and second frequencies and modulated with said baseband information; and
means coupled to said master antenna television cable for receiving and demodulating said third modulated signal to derive said baseband information.

Abstract
A remote ECG monitoring and telemetry system for use in a hospital equipped with a master antenna television cable system comprising a portable patient sensor/transmitter unit for deriving ECG information and for transmitting a first frequency signal modulated with the ECG information; a receiver/transmitter unit positioned in the patient'"'"'s room for receiving the first modulated signal and for coupling directly to the master antenna television cable a second frequency signal modulated with the ECG information; a converter/amplifier unit coupled to the master antenna television cable adjacent the head end thereof for receiving the second modulated signal and for coupling back into the master antenna television cable a high power, third frequency signal modulated with the ECG information; and a receiver/demodulator unit coupled to the master antenna television cable at a central monitoring station for receiving and demodulating the third modulated signal to derive the ECG information.

18. A remote monitoring and telemetry system for use in a facility equipped with a master antenna television cable system comprising:
-
a patient unit comprising; means for deriving baseband information from a patient; means for generating a first frequency signal; means for modulating said first frequency signal with said baseband information; and antenna means for transmitting said first modulated signal; a receiver/retransmitter unit comprising; means for receiving and demodulating said first modulated signal to derive a signal containing said baseband information; means for generating a second frequency signal different from said first frequency signal; means for modulating said second frequency signal with said derived signal containing said baseband information; and means for coupling said second modulated signal to said master antenna television cable; a converter/amplifier unit positioned adjacent the head end of said master antenna television cable comprising; means coupled to said master antenna television cable for receiving said second modulated signal; means operatively coupled to said receiving means for converting said second modulated signal to a third modulated signal having a frequency different from said second frequency; means for amplifying said third modulated signal; and means for coupling said amplified third modulated signal to said master antenna television cable; and a monitoring unit comprising; means coupled to said master antenna television cable for receiving and demodulating said third modulated signal to derive said baseband information. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
