Abstract

A method and apparatus for performing patient monitoring which interfaces a telemetry monitor with a standard portable computer (such as a laptop computer, palmtop computer or personal digital assistant) with the display and the keyboard or other device of the portable computer being utilized to provide both display and input capability to the telemetry monitor. The telemetry monitor is provided with an I/O port which is interfaceable with an I/O port of the portable computer to permit operation as indicated above. Inputs from the user may also be passed through the interface ports and the transmitter of the telemetry monitor to a central station. A back channel may optionally be provided to permit information from the central station to be applied either to control the telemetry monitor or to be passed through the interface ports to the portable processor to provide information to a user.

Claims

1. A patient monitoring device comprising:

a telemetry monitor, said monitor including a physiological monitor for monitoring at least one selected physiological condition of the patient, a transmitter for transmitting information related to the physiological monitor output, and an input/output port, information related to the physiological monitor output also being applied to said port; and

a portable processor having an input device, a display and an input/output port which is interfaceable with the I/O port of the telemetry monitor, said processor receiving physiological monitor related information through its I/O port when the telemetry monitor and processor I/O ports are interfaced and causing a selected indication of said information to be displayed on said display.

2. A device as claimed in claim 1 wherein at least selected information inputted at said input device appears at the processor I/O port, said telemetry monitor receiving the selected information through its I/O port when said ports are interfaced and selectively utilizing said information.

3. A device as claimed in claim 2 wherein said telemetry monitor passes the received selected information to said transmitter for transmission to a central station.

4. A device as claimed in claim 2 wherein said telemetry monitor utilizes the received selected information to control the operation thereof.

5. A device as claimed in claim 4 wherein said received selected information is utilized to change the mode of operation of the physiological monitor.

6. A device as claimed in claim 5 wherein said physiological monitor may monitor a plurality of different physiological conditions, and wherein said received selected information controls the one or more physiological condition monitored.

7. A device as claimed in claim 1 wherein said ports are optical ports which are optically interfaced.

8. A device as claimed in claim 1 wherein said ports are wire sockets, said interfacing being done through an electrical wire.

9. A device as claimed in claim 1 wherein said ports are RF ports.

10. A device as claimed in claim 1 wherein said telemetry monitor includes a receiver for inputs from a central station.

11. A device as claimed in claim 10 wherein at least selected inputs to said receiver are applied by said telemetry monitor to control the operation of said physiological monitor.

12. A device as claimed in claim 10 wherein at least selected inputs to said receiver are passed through said I/O ports to said processor, said processor selectively utilizing said inputs.

13. A device as claimed in claim 1 wherein said monitor is an ECG monitor for monitoring the patient'"'"'s heart function.

14. A device as claimed in claim 1 wherein said selected indication which is displayed is a waveform indication.

15. A method for obtaining and utilizing selected patient information comprising the steps of:

attaching the physiological monitor of a telemetry monitor to the patient to obtain information on a selected physiological condition, said information being applied both to a transmitter and to an input/output port;

interfacing the telemetry monitor I/O port to a compatible I/O port of a portable processor having an input device and a display;

receiving said information at the processor through said I/O ports; and

utilizing the processor'"'"'s display to display at least a selected indication of said information.

16. A method as claimed in claim 15 including the steps of inputting information at the processors input device, passing at least selected portions of said inputted information through the I/O ports to the telemetry monitor, and selectively utilizing the inputted information at the telemetry monitor.

17. A method as claimed in claim 16 wherein said selectively utilizing step includes the step of transmitting selected portions of the inputted information to a central station.

18. A method as claimed in claim 16 wherein said selectively utilizing step includes utilizing the selected portion of the inputted information to control the physiological monitor.

19. A method as claimed in claim 15 including the steps of transmitting selected data from a central station, receiving the selected data at a receiver in said telemetry monitor, and utilizing the received data for at least one of (a) control the operation of the physiological monitor and (b) transmission through the I/O ports for selective utilization by the processor.

20. A method as claimed in claim 15 wherein the display obtained during said utilizing step is utilized during said attaching step to facilitate proper attachment of said physiological monitor to the patient.
