Abstract

A wearable remote device includes a user interface, a strap configured to removably secure the wearable remote device to a wrist of a patient such that the user interface is accessible by the patient, and a wireless transceiver configured to wirelessly communicate with a wearable defibrillator. The wearable remote device includes a processor coupled to the user interface and wireless transceiver to provide a notification relating to at least one of device information relating to the wearable defibrillator and a cardiac arrhythmia communicated by the wearable defibrillator via the wireless transceiver. Responsive to a determination that the notification is of an urgent nature, the processor is configured to cause the user interface to communicate the notification, and responsive to a determination that the notification is not of an urgent nature, cause the user interface to store information relating to the notification in a memory of the wearable remote device.

Claims

1. A wearable remote device comprising:

a user interface;

a strap constructed to removably secure the wearable remote device to a wrist of a patient such that the user interface is accessible by the patient;

a wireless transceiver for wirelessly communicating with a wearable defibrillator; and

a processor, coupled to the user interface and the wireless transceiver, the processor causing the user interface to provide a notification relating to at least one of device information relating to the wearable defibrillator and a cardiac arrhythmia of the patient based on a communication received from the wearable defibrillator via the wireless transceiver,

wherein the processor is configured to determine whether the notification relating to the at least one of the device information relating to the wearable defibrillator and the cardiac arrhythmia is of an urgent nature, and responsive to a determination that the notification is of an urgent nature, causing the user interface to communicate the notification, and responsive to a determination that the notification is not of an urgent nature, causing the user interface to store information relating to the notification in a memory of the wearable remote device; and

first one or more buttons included on the wearable remote device, and configured to be actuated by the patient to respond to the notification of an urgent nature and cause the wearable defibrillator to withhold delivery of a therapy necessitated by a detected cardiac arrhythmia,

wherein the wearable defibrillator comprises second one or more buttons configured to be actuated by the patient to respond to the notification of an urgent nature and cause the wearable defibrillator to withhold delivery of the therapy necessitated by the detected cardiac arrhythmia; and

wherein actuation of either the first one or more buttons or the second one or more buttons causes the wearable defibrillator to withhold delivery of the therapy necessitated by the detected cardiac arrhythmia.

2. The wearable remote device of claim 1, wherein the wireless transceiver includes at least one of a radiofrequency transceiver, a BLUETOOTH transceiver, a wireless Ethernet transceiver, a wireless USB transceiver, and a ZIGBEE transceiver.

3. The wearable remote device of claim 1, further comprising a sensor disposed in the wearable remote device, the sensor including at least one of a pulse rate sensor, a body temperature sensor, and a blood oxygen level sensor.

4. The wearable remote device of claim 1, wherein the user interface includes at least one of a display, a user interactive display, the first one or more buttons included as touch screen display buttons displayed on the user interface, an audio output device, and an electro-mechanical vibrator.

5. The wearable remote device of claim 1, wherein the first one or more buttons comprise one or more buttons disposed on a housing of the wearable remote device for receiving input from the patient.

6. The wearable remote device of claim 1, wherein the first one or more buttons can be actuated by the patient to acknowledge the notification.

7. The wearable remote device of claim 6, wherein responsive to the patient acknowledging the notification, the wearable remote device transmits an acknowledgement of the notification to the wearable defibrillator.

8. The wearable remote device of claim 6, wherein responsive to a lack of acknowledgement by the patient, the processor causes the user interface to repeat the notification with different characteristics.

9. The wearable remote device of claim 1, wherein the user interface includes a display disposed on a housing of the wearable remote device, and wherein the processor causes the display to display a visual notification relating to the at least one of the device information relating to the wearable defibrillator and the cardiac arrhythmia of the patient.

10. The wearable remote device of claim 1, wherein the user interface includes an audio output device disposed in the wearable remote device, and wherein the processor causes the audio output device to provide an audible notification relating to the at least one of the device information relating to the wearable defibrillator and the cardiac arrhythmia of the patient.

11. The wearable remote device of claim 10, wherein the audible notification includes at least one of an audible alarm siren or tone, a voice message, and a voice prompt.

12. The wearable remote device of claim 10, wherein the user interface further includes a display disposed on a housing of the wearable remote device, and wherein the processor further causes the display to display a visual notification relating to the at least one of the device information relating to the wearable defibrillator and the cardiac arrhythmia of the patient.

13. The wearable remote device of claim 12, wherein the notification relates to device information relating to the wearable defibrillator, the device information identifying a state of charge on a battery powering the wearable defibrillator.

14. The wearable remote device of claim 12, wherein the notification relates to device information relating to the wearable defibrillator, the device information identifying a number of sensors associated with the wearable defibrillator have fallen off or lost contact with the body of the patient.

15. The wearable remote device of claim 12, wherein the notification relates to the cardiac arrhythmia of the patient and at least one of the visual notification and the audible notification indicates the cardiac arrhythmia has been detected and a shock is to be delivered by the wearable defibrillator.

16. The wearable remote device of claim 15, wherein the first one or more buttons can be actuated by the patient to communicate a condition of the patient to the wearable defibrillator in response to the notification relating to the cardiac arrhythmia.

17. The wearable remote device of claim 16, wherein the at least one of the visual notification and the audible notification further prompts the patient to actuate the first one or more buttons to withhold the shock from being delivered by the wearable defibrillator.

18. The wearable remote device of claim 17, wherein, responsive to the patient actuating the first one or more buttons, the processor sends a communication to the wearable defibrillator via the wireless transceiver instructing the wearable defibrillator to withhold the shock.

19. The wearable remote device of claim 16, further comprising at least one of a telephone communication interface, a cellular communication interface, and a wireless computer network communication interface.

20. The wearable remote device of claim 19, wherein, the processor further causes the at least one of the telephone communication interface, the cellular communication interface, and the wireless computer network communication interface to communicate a message to at least one of emergency personnel at a remote location, a medical service provider of the patient, and a loved one or relative of the patient.

21. The wearable remote device of claim 20, wherein the message identifies at least one of an identity of the patient, a medical condition of the patient, and a physical location of the patient.
