Abstract

A medical device including a control circuit and a plurality of selectable communication modes. The control circuit controls the medical device and generates a signal representative of a characteristic of the medical device. A selected one of the plurality of selectable communication modes communicates the signal generated by the control circuit at a configurable messaging rate.

Claims

1. A medical device comprising:

a control circuit for controlling the medical device, said control circuit generating a signal representative of a characteristic of the medical device; and

a plurality of switchable and selectable communication modes of the control circuit for communicating the signal generated by the control circuit at a user-configurable messaging rate, said user-configurable messaging rate having a single value selectable from zero, a preset interval, and a query interval.

2. The medical device of claim 1, wherein the selectable communication modes comprise at least the following:

a first communications mode enabling the device to periodically report a status message at the preset interval;

a second communications mode enabling the device to report a status message in response to a query at the query interval; and

a third communications mode disabling the device from reporting a status message when the user-configurable messaging rate is zero.

3. The medical device of claim 2, further comprising a user interface responsive to user input for selecting one of the first, second, or third communications modes.

4. The medical device of claim 1, wherein the selectable communications modes include a default communications mode.

5. The medical device of claim 4, wherein the control circuit is configured to disable the device from reporting a status message when in the default communications mode.

6. The medical device of claim 4 wherein the control circuit is configured to enable the device to periodically report a status message when in the default communications mode.

7. The medical device of claim 1, wherein the control circuit is responsive to user input for selecting among the plurality of selectable communications modes.

8. The medical device of claim 7, wherein the user input comprises a status query.

9. The medical device of claim 1, further comprising a user interface responsive to user input for selecting one of the selectable communications modes.

10. The medical device of claim 1, further comprising a serial port coupled to the control circuit for communicating the signal generated by the control circuit according to a selected one of the communications modes and for receiving a selection of one of the communications modes.

11. The medical device of claim 1, further comprising a wireless transmitter coupled to the control circuit for communicating the signal generated by the control circuit according to a selected one of the communications modes and for receiving a selection of one of the communications modes.

12. A method of communicating a status of a medical device comprising:

supplying power to the medical device;

selecting one of a plurality of switchable and selectable communications modes of said medical device, said selecting comprising receiving a single specification of a configurable messaging rate having a value chosen from zero, a preset interval, and a query interval;

loading the selected communications mode to an operating communications mode; and

transmitting the status of the medical device in accordance with said operating communications mode at the specified configurable messaging rate.

13. The method of claim 12, wherein transmitting the status of the medical device comprises sending a message indicating the status at a preset interval.

14. The method of claim 12, wherein transmitting the status of the medical device comprises sending a message indicating the status in response to a status query.

15. The method of claim 12, wherein selecting one of the plurality of selectable communications modes of said medical device comprises receiving a communications signal and altering the operating communications mode of said medical device in response to receiving the communications signal.

16. The method of claim 15, wherein said communications signal is a status query.

17. The method of claim 12, wherein selecting the communications mode comprises receiving user input via a user interface for selecting one of the plurality of selectable communications modes.

18. The method of claim 12, wherein the selectable communications modes comprise at least the following:

a first communications mode enabling the device to periodically report a status message;

a second communications mode enabling the device to report a status message in response to a query; and

a third communications mode disabling the device from reporting a status message.

19. The method of claim 18, wherein selecting one of the plurality of selectable communications modes comprises selecting one of the first, second, or third communications modes as a default communications mode.

20. The method of claim 12, wherein transmitting the status of the medical device comprises communicating the status via a serial port.

21. The method of claim 12, wherein transmitting the status of the medical device comprises communication the status via wireless transmission.

22. A medical device status monitoring system comprising:

at least one medical device having a first communications device for sending status messages at a configurable messaging rate and receiving status queries, said configurable messaging rate having a value selectable from zero, a preset interval, and a query interval, said at least one medical device having a plurality of switchable and selectable communications modes;

a server having a second communications device for receiving said status messages and for sending said status queries; and

a communication medium for transferring said status messages from the at least one medical device to the server, and for transferring said status queries from the server to the at least one medical device.

23. The medical device status monitoring system of claim 22, wherein the selectable communications modes of the medical device comprise at least the following:

a first communications mode enabling the device to periodically report a status message;

a second communications mode enabling the device to report a status message in response to a query; and

a third communications mode disabling the device from reporting a status message.

24. The medical device status monitoring system of claim 23, wherein the medical device comprises a user interface for selecting one of the first, second, or third communications modes.

25. The medical device status monitoring system of claim 22, wherein the selectable communications modes of the medical device include a default communications mode.

26. The medical device status monitoring system of claim 25, wherein the medical device is configured to be disabled from reporting a status message when in the default communications mode.

27. The medical device status monitoring system of claim 25, wherein the medical device is configured to be enabled to periodically report a status message when in the default communications mode.

28. The medical device status monitoring system of claim 22, wherein the medical device is responsive to user input for selecting among the plurality of selectable communications modes.

29. The medical device status monitoring system of claim 28, wherein the user input to the medical device comprises the status query sent by the server.

30. An enteral feeding pump comprising:

a control circuit for controlling operation of the pump, said control circuit generating a signal representative of an operational characteristic of the pump; and

a plurality of switchable and selectable communication modes for communicating the signal generated by the control circuit at a configurable messaging rate, said configurable messaging rate having a single value selectable from zero, a preset interval, and a query interval.

31. The pump of claim 30, wherein the selectable communications modes comprise at least the following:

a first communications mode enabling the device to periodically report a status message;

a second communications mode enabling the device to report a status message;

and a third communications mode disabling the device from reporting a status message.
