Abstract

The invention relates to a medical parameter monitoring device which allows the monitoring of a plurality of medical parameters from a remote location. The invention uses a central monitoring system which transmits and receives date parameters via RF from remote patient monitors. The monitoring system utilized a digital spread spectrum RF transceiver between the central monitoring system to the remote monitors. Forward error correcting, frequency hopping, and spread sprectrum communications are employed to provide accurate transmission of data for a plurality of physiological parameters. Transmitted data can be automatically registered into storage in the central monitoring system.

Claims

9. A system to monitor physiological data, comprising:

sensors for blood pressure, pulse rate, blood oxygen concentration and electrocardiographic information;

a patient monitor coupled to the sensors for continually collecting and transmitting the physiological data corresponding to a patient, the patient monitor including a display;

a central monitoring system for storage, analysis, and display of continuous physiological data, the central monitoring system including a transmitter for transmitting at least one monitoring parameter to said patient monitor;

a digital spread-spectrum radio-frequency transmitter for transmitting physiological data from said monitor to said central monitoring system.

19. The system as defined in claim 9, wherein the monitoring parameter is a waveform specification.

20. The system as defined in claim 9, wherein the monitoring parameter is a sampling rate.

21. The system as defined in claim 9, further comprising a second central monitoring system.

22. The system as defined in claim 9, wherein a dynamic waveform is displayed on the display of the patient monitor.

15. A method for providing simultaneous monitoring of at least one physiological parameter of a patient at a plurality of locations, the method comprising the following steps:

coupling at least one patient monitor including a display and a transceiver to the patient;

establishing a bi-directional RF communications link using spread spectrum digital transmissions in the ISM band between the patient monitor and a central monitoring system;

selecting the physiological parameters to monitor and at least one waveform characteristic of the central monitoring system;

transmitting the selected physiological parameter and the selected waveform characteristic to the patient monitor;

collecting the physiological parameter;

displaying a continuous waveform representation of the physiological parameters at the patient monitor;

displaying a continuous waveform representation of the physiological parameter at the central monitoring system.

16. The method as defined in claim 15, further comprising the step of selecting a sampling rate at the central monitoring system.

17. The method as defined in claim 15, further comprising the step of detecting a patient location.

18. The method as defined in claim 15, further comprising the step of coupling a second patient monitor to a second patient.
