Abstract

An ambulatory medical device is provided. The ambulatory medical device includes at least one sensor configured to acquire physiological data of a patient, at least one network interface and at least one processor coupled to the at least one sensor and the at least one network interface. The at least one processor is configured to detect, via the at least one network interface, a medical device, to establish a secure communication session with the medical device via the at least one network interface, to detect a data capacity of the secure communication session, to identify a category of patient data associated with the data capacity, and to transmit patient data of the category to the medical device via the secure communication session.

Claims

1. An ambulatory medical device comprising:

at least one sensor configured to acquire electrocardiogram data of a patient;

at least one network interface; and

at least one processor coupled to the at least one sensor and the at least one network interface and configured to

detect, via the at least one network interface, a medical device in response to the ambulatory medical device entering a predefined range of the medical device;

establish a secure communication session with the medical device via the at least one network interface;

detect a data capacity of the secure communication session;

identify a category of patient data associated with the data capacity; and

transmit patient data of the category to the medical device via the secure communication session.

2. The ambulatory medical device of claim 1, wherein the at least one processor is configured to determine whether the medical device is within the predefined range based on at least one of a Wi-Fi signal strength, a BLUETOOTH signal strength, and a near field communication signal strength.

3. The ambulatory medical device of claim 1, wherein the at least one processor is configured to determine the medical device is within the predefined range based on physical contact between the medical device and at least one of the ambulatory medical device and the patient.

4. The ambulatory medical device of claim 1, wherein the at least one processor is configured to determine whether the medical device is trusted prior to establishing the secure communication session.

5. The ambulatory medical device of claim 1, wherein the patient data comprises a summary based on the electrocardiogram data, the summary describing one or more of a heart rate of the patient, a heartbeat of the patient, an arrhythmia determination regarding the patient, and an arrhythmia detection alert regarding the patient.

6. The ambulatory medical device of claim 5, wherein the at least one processor is configured to monitor the data capacity and to include the electrocardiogram data within the patient data where the data capacity exceeds a predetermined threshold.

7. The ambulatory medical device of claim 5, further comprising at least one electrode configured to shock the patient.

8. The ambulatory medical device of claim 7, further comprising a garment housing the at least one electrode.

9. The ambulatory medical device of claim 1, wherein the at least one processor is configured to receive, within the secure communication session, instructions to treat the patient from the medical device and to execute the instructions to treat the patient via the ambulatory medical device.

10. The ambulatory medical device of claim 9, wherein the at least one processor is configured to implement a web server configured to receive the instructions within the secure communication session, to transmit the patient data to a programmable device distinct from the medical device and the ambulatory medical device, or both to receive the instructions within the secure communication session and to transmit the patient data to the programmable device distinct from the medical device and the ambulatory medical device.

11. The ambulatory medical device of claim 10, wherein the programmable device comprises at least one of a mobile computing device, a remote server, and a hospital data system.

12. The ambulatory medical device of claim 11, wherein the patient data comprises data descriptive of one or more of activity of the patient, compliance of the patient, body position of the patient, at least one electrocardiogram reading of the patient, at least one heart sound of the patient, respiration of the patient, blood oxygen level of the patient, demographics of the patient, and medical history of the patient.

13. The ambulatory medical device of claim 1, wherein the at least one processor is configured to receive instructions to execute a diagnostic protocol from the medical device and to execute the diagnostic protocol.

14. The ambulatory medical device of claim 13, further comprising a user interface coupled to the at least one processor, wherein the diagnostic protocol includes a six-minute walk test and the at least one processor is configured to prompt the patient, via the user interface, to perform the six-minute walk test.

15. The ambulatory medical device of claim 13, wherein the diagnostic protocol comprises a self-administered diagnostic protocol.

16. The ambulatory medical device of claim 1, wherein the at least one processor is configured to detect a predefined patient condition and to transmit instructions for the medical device to issue an alert via a user interface regarding the predefined patient condition.

17. The ambulatory medical device of claim 1, wherein the category of patient data comprises summary data descriptive of the patient.

18. The ambulatory medical device of claim 17, wherein the summary data comprises one or more of heart rate data for the patient, arrhythmia detection information, and detection alert information.

19. The ambulatory medical device of claim 1, wherein the category of patient data comprises detailed data descriptive of the patient.

20. The ambulatory medical device of claim 19, wherein the detailed data comprises electrocardiogram data for the patient.

21. The ambulatory medical device of claim 1, wherein the category of patient data comprises one or more of detailed data descriptive of the patient and summary data generated based upon the detailed data.

22. The ambulatory medical device of claim 21, wherein the detailed data corresponds to a higher data capacity threshold than the summary data.

23. A method of integrating an ambulatory medical device with a hospital medical device, the method comprising:

acquiring, by the ambulatory medical device, electrocardiogram data of a patient;

detecting, by the ambulatory medical device, the hospital medical device in response to the ambulatory medical device entering a predefined range of the hospital medical device;

establishing a secure communication session between the ambulatory medical device and the hospital medical device;

detecting, by the ambulatory medical device, a data capacity of the secure communication session;

identifying, by the ambulatory medical device, a category of patient data associated with the data capacity; and

transmitting, by the ambulatory medical device, patient data of the category to the hospital medical device via the secure communication session.

24. The method of claim 23, further comprising determining whether the hospital medical device is trusted prior to establishing the secure communication session.
