Abstract

A wearable defibrillation system includes an output device and a motion sensor. The output device emits a sound or a vibration for the patient, who responds by deliberately tapping the system. The motion sensor registers the tapping, and interprets it as a reply from the patient. The reply can be that the patient is conscious, or convey data that the patient enters by tapping the right number of times, or that the patient wants attention, and so on. Since the patient does not need direct access to the wearable defibrillation system for tapping it, he or she can wear it under their other garments, which helps preserve their dignity and privacy.

Claims

1. A wearable defibrillator system, comprising:

a support structure for wearing by a patient;

electrodes for delivering a charge to the patient, while the patient is wearing the support structure;

an output device;

a processor for inputting a query, and for causing the output device to emit a questioning human-perceptible indication that conveys the query;

a motion sensor configured to detect motion of the patient while the patient responds to the query; and

a communication module for transmitting a communication to a third party responsive to a motion detected by the motion sensor after the questioning human-perceptible indication is emitted.

2. The system of claim 1, in which

the output device includes a speaker.

3. The system of claim 1, in which

the output device includes a vibration mechanism.

4. The system of claim 1, in which

an unscheduled motion is detected, and

the query is input responsive to the unscheduled motion.

5. The system of claim 4, in which

a plurality of unscheduled motions following a pattern are detected, and

the query is input responsive to the plurality of unscheduled motions.

6. The system of claim 1, further comprising:

a monitoring device for monitoring patient data, and

in which the query is input responsive to a value of the patient data exceeding a threshold.

7. The system of claim 1, in which

the output device includes a vibration mechanism, and

the questioning human-perceptible indication conveys the query as a pattern of vibrations, such that

the query has a first meaning if the pattern of vibrations is a first pattern, and

the query has a second meaning different from the first meaning if the pattern of vibrations is a second pattern different from the first pattern.

8. The system of claim 1, in which

the communication to the third party is transmitted only if the motion is detected within a respond interval that starts when the questioning human-perceptible indication is caused to be emitted, and

if no motion is detected within the respond interval, the processor causes the output device to emit another human-perceptible indication.

9. The system of claim 1, in which

an echo human-perceptible indication is further caused to be emitted for each detected motion that is interpreted to have been caused by each tapping.

10. The system of claim 1, in which

a confirming human-perceptible indication is caused to be emitted, and

the communication to the third party is transmitted only if another motion signal is then received from the motion sensor.

11. A non-transitory computer-readable storage medium storing one or more programs which, when executed by a processor of a wearable defibrillator system that is worn by a patient, and has a motion sensor, an output device, and a communication module, they result in:

inputting a query;

causing the output device to emit a questioning human-perceptible indication that conveys the query;

then receiving a detection signal from the motion sensor wherein the motion sensor is configured to detect motion of the patient while the patient responds to the query; and

causing a communication to be transmitted to a third party responsive to the detection signal.

12. The medium of claim 11, in which

an unscheduled detection signal is received, and

the query is input responsive to the unscheduled detection signal.

13. The medium of claim 12, in which

a plurality of unscheduled detection signals following a pattern are received, and

the query is input responsive to the plurality of unscheduled detection signals.

14. The medium of claim 11, in which

the wearable defibrillator system further has a monitoring device for monitoring patient data, and

in which the query is input responsive to a value of the patient data exceeding a threshold.

15. The medium of claim 11, in which

the output device includes a vibration mechanism, and

the questioning human-perceptible indication conveys the query as a pattern of vibrations, such that:

the query has a first meaning if the pattern of vibrations is a first pattern, and

the query has a second meaning different from the first meaning if the pattern of vibrations is a second pattern different from the first pattern.

16. The medium of claim 11, in which

an echo human-perceptible indication is further caused to be emitted for each detection signal that is interpreted to have been caused by each tapping.

17. The medium of claim 11, in which

the communication to the third party is caused to be transmitted only if the detection signal is received within a respond interval that starts when the questioning human-perceptible indication is caused to be emitted, and

if no detection signal is received within the respond interval, the output device is caused to emit another human-perceptible indication.

18. The medium of claim 11, in which executing the one or more programs further results in:

causing to be emitted a confirming human-perceptible indication, and

in which the communication to the third party is transmitted only if another detection signal is then received from the motion sensor.

19. A wearable defibrillator system, comprising:

a support structure for wearing by a patient;

electrodes for delivering a charge to the patient, while the patient is wearing the support structure;

an output device;

a processor for inputting a query, and for causing the output device to emit a questioning human-perceptible indication that conveys the query;

a monitoring device for monitoring patient data; and

a motion sensor configured to detect motion of the patient while the patient responds to the query; and

a memory for storing the patient data responsive to a motion detected by the motion sensor after the questioning human-perceptible indication is emitted.

20. A non-transitory computer-readable storage medium storing one or more programs which, when executed by a processor of a wearable defibrillator system that is worn by a patient, and has a motion sensor, an output device, a memory, and a monitoring device, they result in:

monitoring patient data;

inputting a query;

causing the output device to emit a questioning human-perceptible indication that conveys the query;

then receiving a detection signal from the motion sensor wherein the motion sensor is configured to detect motion of the patient while the patient responds to the query; and

causing the patient data to be stored in the memory responsive to the detection signal.

21. A wearable defibrillator system, comprising:

a support structure for wearing by a patient;

electrodes for delivering a charge to the patient, while the patient is wearing the support structure;

an output device;

a processor for inputting a query, and for causing the output device to emit a questioning human-perceptible indication that conveys the query;

a motion sensor configured to detect motion of the patient while the patient responds to the query; and

a memory for storing a reply to the query responsive to a motion detected by the motion sensor after the questioning human-perceptible indication is emitted, the reply in accordance with the detected motion.

22. A non-transitory computer-readable storage medium storing one or more programs which, when executed by a processor of a wearable defibrillator system that is worn by a patient, and has a motion sensor, an output device and a memory, they result in:

24. The method of claim 23, further comprising:

tapping proximately to the support structure prior to perceiving the questioning indication, and
