Abstract

A medical device such as a defibrillator that incorporates corrective voice prompts that navigate users around operator errors. The voice prompts may, for example, address errors of readiness (e.g., failing to connect the defibrillator to an AC power source, failing to pre-connect electrodes, etc.), errors of omission (i.e., forgetting to do something, such as attempting to deliver a shock before the defibrillator is charged), and errors of commission (i.e., doing the wrong thing, such as attempting to shock VF when in the synchronization mode). The voice prompts may address errors in the delivery of therapy (e.g., attempting to shock VF when in the synchronization mode) or they may address errors other than in the delivery of therapy (e.g., failing to connect to an AC power source).

Claims

1. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising the operator'"'"'s failure to connect the device to AC power

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.

2. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising operator errors associated with the storage, management, deletion, transmission, or correction of information;

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.

3. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising operator errors associated with the use of removable forms of media,

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.

4. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising operator errors associated with the use of wired or wireless transmission of data,

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.

5. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising operator errors associated with recording, displaying, storing, or printing of electrocardiographic (ECG) data,

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.

6. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising operator errors related to analysis of electrocardiographic (ECG) data,

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.

7. A medical device of the type used for assisting a user in delivering therapy to a patient, the device comprising

a user interface including a speaker configured to deliver voice prompts to a user to assist the user in operating the device;

at least one sensor or circuit element configured to detect an error made by the user in the manner in which the user operates the device, the error comprising one or more errors in calibration, sensor replacement, environmental issues (ambient lighting) or cable placement,

a memory in which a plurality of different voice prompts are stored;

a processor configured to determine which of the different voice prompts should be selected for delivery based on the detected error; and

circuitry configured to work with the memory and the user interface and speaker to deliver the selected voice prompt to assist the user in correcting the error.
