Abstract

An external medical device is provided which is configured to provide a user with access to one or more training modules. The external medical device includes one or more electrodes configured to detect a cardiac activity of a patient, an audio and/or visual output, and a controller coupled to the audio and/or visual output. The controller is configured to: detect at least one of a predetermined event and a device use pattern; and responsive to detecting the at least one of the predetermined event and the device use pattern, provide the patient access to one or more training modules relating to a use or a configuration of the external medical device via the audio and/or visual output. The device can also include a user interface configured to provide access to at least one training module according to a schedule of training modules for the patient.

First claim

What is claimed is:

1. A wearable cardiac device comprising:
a computer readable memory;
a rechargeable battery;
a garment configured to be worn on a body of a patient;
one or more electrodes that are attached to the garment, that are configured to position against the body of the patient, and that are configured to detect a cardiac activity of the patient;
an audio and/or visual user interface comprising a display and/or a speaker for communicating training information to the patient; and
a controller that is powered by the rechargeable battery, the controller coupled to the computer readable memory and the audio and/or visual user interface, wherein the controller is configured to:
output, to the patient via the audio and/or visual user interface, a list of available training modules;
receive, from the patient via the audio and/or visual user interface, a user selection that identifies a first training module included in the list;
output the first training module to the patient via the audio and/or visual user interface, the first training module comprising instructions for laundering the garment, instructions for positioning the one or more electrodes with respect to the garment and the body of the patient, and/or instructions for charging the rechargeable battery;
record, in the computer readable memory, a plurality of alerts provided to the patient, the alerts indicating improper use of the wearable cardiac device by the patient;
detect a device use pattern indicative of the improper use of the wearable cardiac device by the patient based at least in part on the plurality of alerts;
automatically identify a second training module that instructs the patient as to a use or a configuration of the wearable cardiac device responsive to detecting the device use pattern; and
output the second training module to the patient via the audio and/or visual user interface.

2. The wearable cardiac device of claim 1 , wherein the first training module further comprises instructions for device setup, instructions for responding to one or more of the plurality of alerts, and/or instructions for connecting the one or more electrodes to the controller.

3. The wearable cardiac device of claim 1 , further comprising one or more sensors for detecting a status of the wearable cardiac device, wherein the controller is configured to detect the device use pattern indicative of the improper use of the wearable cardiac device based, at least in part, on measurements received from the one or more sensors and to inform the patient of the device use pattern indicative of the improper use via the audio and/or visual user interface.

4. The wearable cardiac device of claim 3 , wherein the one or more sensors for detecting the status of the wearable cardiac device comprise an accelerometer, a temperature sensor, a gyroscope sensor, a drop detection sensor, a battery charge sensor, and/or a battery viable life sensor.

5. The wearable cardiac device of claim 1 , further comprising one or more sensors for determining the configuration of the wearable cardiac device, wherein the improper use comprises an improper configuration, and the controller is configured to identify the improper configuration of the wearable cardiac device based, at least in part, on information received from the one or more sensors and to inform the patient of the improper configuration via the audio and/or visual user interface.

6. The wearable cardiac device of claim 1 , further comprising a transceiver configured to receive (a) the first and second training modules or (b) an updated training module from an external source, wherein the controller is configured to provide a notification to a third party via the transceiver upon detection of the device use pattern indicative of the improper use of the wearable cardiac device.

7. The wearable cardiac device of claim 1 , wherein the first and second training modules collectively comprise a video, an animation sequence, a plurality of still images, text messages, recorded messages, interactive content, quizzes, and/or surveys.

8. The wearable cardiac device of claim 1 , wherein outputting the first training module to the patient comprises scheduling a time for the patient to use the first training module, informing the patient of the scheduled time via the audio and/or visual user interface, and, subsequently, providing notifications to the patient to remind the patient of the scheduled time.

9. The wearable cardiac device of claim 8 , wherein at least one of the notifications includes an option for delaying the first training module to a later time.

10. The wearable cardiac device of claim 1 , further comprising one or more sensors configured to measure information representative of: a respiration level of the patient, a heart sound and movement of the patient, a lung sound and movement of the patient, a tissue fluid level of the patient, a blood pressure of the patient, a glucose level of the patient, and/or a blood oxygenation level of the patient.

11. The wearable cardiac device of claim 1 , further comprising a wearable defibrillator that comprises:
at least one therapy pad connected to or embedded in the garment and connected to a defibrillation shock generator; and
one or more sensors configured to monitor a status of the wearable defibrillator,
wherein the controller is operatively connected with the defibrillation shock generator and the one or more sensors, and
wherein the controller is configured to detect the device use pattern indicative of the improper use of the wearable cardiac device based, at least in part, on information from the one or more sensors.

12. The wearable cardiac device of claim 11 , wherein the one or more sensors comprise a contact sensor to confirm contact between the one or more electrodes and the patient; a sensor associated with a latch or buckle of the garment to identify if the garment is secured to the patient; a sensor for confirming that the one or more electrodes are connected to the controller; a sensor for identifying a position of the one or more electrodes on the body of the patient; and/or a sensor associated with the at least one therapy pad to determine a position of the at least one therapy pad relative to the patient.

13. The wearable cardiac device of claim 1 , wherein the improper use comprises device impact, dropping the device, water exposure, improper configuration, noncompliance with prescribed use, and/or noncompliance with recommended use.

14. The wearable cardiac device of claim 13 , further comprising one or more sensors configured to monitor for the improper use, wherein the controller is configured to receive sensor readings from the one or more sensors indicative of the improper use.

15. The wearable cardiac device of claim 1 , wherein:
the first training module further comprises instructions for device setup; and
the controller is further configured to output the first training module to the patient (a) prior to an initial wearing of the garment by the patient, and (b) between 24 and 72 hours after the initial wearing of the garment by the patient.

16. The wearable cardiac device of claim 1 , wherein:
the first training module is a recurring training module that is scheduled for repeated use by the patient; and
the controller is further configured to output the first training module at predetermined intervals of wearing the garment.

17. A wearable cardiac device comprising:
a computer readable memory;
a rechargeable battery;
a garment configured to be worn on a body of a patient;
one or more electrodes
