Abstract

A small, portable infusion device for ambulatory use by a patient includes an audible enunciator integrated circuit chip. This chip is controlled by a microprocessor to provide output data to an operator, and to work in place of, or in association with a visual output display, such as an LCD screen. The audible data output permits a remote clinician to monitor operation of the pump, and diagnose and correct problems with the pump'"'"'s operation.

Claims

1. A system for monitoring an ambulatory infusion pump comprising:

an ambulatory infusion pump;

a plurality of verbal messages stored such that they can be audibly accessed;

a control panel on the infusion pump; and

means for audibly accessing the plurality of stored messages when the control panel is manipulated.

2. The system as defined in claim 1 wherein the verbal messages are digitally stored in a digital voice storage chip which stores a vocabulary of individually addressable words.

3. The system as defined in claim 1 wherein the control panel comprises a plurality of keys which control the rate of flow through the ambulatory infusion pump.

4. The system as defined in claim 3 wherein at least one of the plurality of verbal messages is audibly accessed when each key is depressed.

5. A method of monitoring an ambulatory infusion pump comprising the steps of:

providing an ambulatory infusion pump having a control panel and a storage device containing a plurality of stored verbal messages such that the verbal messages can be audibly accessed;

manipulating the control panel such that the verbal messages are audibly accessed; and

listening to the audible verbal messages.

6. The method of claim 5 further comprising:

responding to the audible verbal messages by manipulating the control panel again.

7. The method of claim 5 wherein the listening step is accomplished in a remote location by means for transmitting the audible verbal message to the remote locational.

8. The method of claim 5 wherein the manipulating step and listening step are performed by separate individuals.

9. The method of claim 8 further comprising the steps of responding to the audible verbal message by the individual who performed the listening step instructing the individual who performed the manipulating step how to manipulate the control panel again.

10. A method of reprogramming an infusion pump from a remote location comprising the steps of:

providing an ambulatory infusion pump having a control panel;

providing a plurality of stored verbal messages audibly accessible by the control panel;

providing a standard telephone;

manipulating the control panel by a first individual in the location of the infusion pump such that the verbal messages are audibly accessed;

transmitting the verbal messages to a remote location using the standard telephone;

responding to the verbal messages by a second individual in the remote location instructing the first individual how to manipulate the control panel; and

manipulating the control panel by the second individual;

whereby the manipulation of the control panel results in a new program for the infusion pump.

11. The method of claim 10 wherein the control panel includes a speaker which is accessible by the stored verbal messages to audibilize the message.

12. The method of claim 11 wherein the standard telephone includes a standard handset and the step of transmitting the audible verbal message includes holding the handset near the speaker.

13. The method of claim 10 further comprising the steps of:

manipulating the control panel again by the first individual such that an updated verbal message is accessed; and

transmitting the updated verbal message to the remote location using the standard telephone;

whereby the second individual may verify that the infusion pump has been correctly reprogrammed.
