Abstract

A wearable defibrillator includes a plurality of ECG electrodes removably attached to a patient and configured to sense a cardiac condition of the patient, and at least one therapy pad configured to deliver electrical therapy to the patient. The wearable defibrillator may include a microphone configured to receive an audio input and sense environmental noise and a speaker configured to output one or more alarms signaling that treatment is about to be provided to the patient. At least one processor of the wearable defibrillator is operatively connected to the plurality of ECG electrodes, the at least one therapy pad, a memory, and the at least one audio device. The at least one processor is configured to monitor the sensed cardiac condition and increase a volume of the one or more alarms when the microphone senses from the environmental noise that the wearable defibrillator is in a high noise environment.

First claim

What is claimed is:

1. A wearable defibrillator comprising:
a plurality of ECG electrodes configured to be removably attached to a patient and configured to sense a cardiac condition of the patient;
at least one therapy pad configured to deliver electrical therapy to the patient;
at least one audio device, the at least one audio device including
a microphone configured to receive an audio input and sense environmental noise, and
a speaker configured to output one or more alarms signaling that treatment is about to be provided to the patient; and

at least one processor operatively connected to the plurality of ECG electrodes, the at least one therapy pad, a memory, and the at least one audio device, the at least one processor configured to
monitor the sensed cardiac condition, and
increase a volume of the one or more alarms when the microphone senses from the environmental noise that the wearable defibrillator is in a high noise environment.

2. The wearable defibrillator of claim 1 , wherein the cardiac condition comprises an arrhythmia.

3. The wearable defibrillator of claim 2 , wherein the at least one audio device further comprises an audio amplifier.

4. The wearable defibrillator of claim 2 , wherein the at least one processor is configured to emit the one or more alarms at different frequencies.

5. The wearable defibrillator of claim 2 , wherein the at least one processor is configured to increase the volume to permit the one or more alarms to be heard by the patient or people near the patient.

6. The wearable defibrillator of claim 1 , wherein the at least one processor is configured to output the one or more alarms as a customized voice message for the patient.

7. The wearable defibrillator of claim 6 , wherein the customized voice message comprises a name of the patient.

8. The wearable defibrillator of claim 6 , wherein the customized voice message comprises personalized instructions.

9. The wearable defibrillator of claim 1 , wherein the at least one processor is configured to output one or more health survey questions to the patient.

10. The wearable defibrillator of claim 9 , wherein the one or more health survey questions relate to one or more symptoms experienced by the patient.

11. The wearable defibrillator of claim 10 , wherein the memory stores a voice signature and the at least one processor is configured to identify a person's voice and determine when the patient is providing the audio input.

12. The wearable defibrillator of claim 1 , wherein the at least one processor is configured to output a responsiveness inquiry via the speaker to the patient.

13. The wearable defibrillator of claim 12 , wherein the at least one processor is configured to output one or more instructions related to the responsiveness inquiry via the speaker.

14. The wearable defibrillator of claim 1 , wherein the at least one processor is configured to record the audio input for later review and determination of a diagnosis for the patient.

15. The wearable defibrillator of claim 1 , wherein the at least one processor is configured to output via the speaker survey queries stored in the memory, the survey queries comprising queries regarding the patient's health or a condition of the wearable defibrillator.

16. The wearable defibrillator of claim 15 , wherein the memory is configured to store the patient's responses to the survey queries, and the at least one processor is configured to track the patient's responses to verify the patient is not experiencing any symptoms indicating increased risk of experiencing a condition that may require treatment.

17. The wearable defibrillator of claim 1 , wherein the at least one processor is configured to cause a self-diagnostic test to be run if the audio input comprises a high amplitude and short duration noise.

18. The wearable defibrillator of claim 17 , wherein the at least one processor is configured to cause the self-diagnostic test to be run by causing an alarm to be emitted at different frequencies and volumes and verifying the alarm is being emitted at different volumes and frequencies by comparing an expected audio output with the audio input received by the microphone.
