Abstract

At least one aspect is directed to a wearable treatment device that includes a cardiac sensing electrode, a treatment electrode, a user interface, and a sensor. The cardiac sensing electrode detects cardiac information, and the treatment electrode applies treatment to the subject. The user interface receives quality of life information from the subject, and the sensor detects subject activity and wellness information. A controller coupled with the cardiac sensing electrode, the treatment electrode, the user interface, and the sensor receives the detected cardiac information, the quality of life information, and the detected subject activity and wellness information, and determines that treatment is to be applied to the body of the subject based upon the detected cardiac information. The controller can also adjust the treatment based on at least one of the detected subject activity and wellness information and the quality of life information, and an alarm module provides an alarm after the cardiac information is detected and before the treatment is applied to the body of the subject.

Claims

1. A wearable treatment device for treatment of a subject, comprising:

a cardiac sensing electrode configured to be positioned outside a body of the subject and to detect cardiac information of the subject;

a treatment electrode configured to be positioned outside the body of the subject and to apply treatment to the subject;

a user interface configured to receive quality of life information from the subject;

a sensor configured to be positioned outside the body of the subject and to detect subject activity and wellness information indicative of a general wellness of the subject;

a controller communicatively coupled to the cardiac sensing electrode, the treatment electrode, the user interface, and the sensor, the controller configured to receive the detected cardiac information, the quality of life information, and the detected subject activity and wellness information, to determine that treatment is to be applied to the body of the subject based upon the detected cardiac information, and to adjust the treatment based on at least one of the detected subject activity and wellness information and the quality of life information; and

an alarm module configured to provide an alarm after the cardiac information is detected and before the treatment is applied to the body of the subject.

2. The treatment device of claim 1, wherein the alarm module is configured to provide a second instance of the alarm after the treatment is applied to the body of the subject.

3. The treatment device of claim 1, wherein the user interface is configured to prevent application of the treatment to the body of the subject.

4. The treatment device of claim 1, comprising:

a second sensor configured to be positioned outside the body of the subject and to detect subject activity and wellness information; and

the controller configured to determine that the treatment device is properly positioned on the subject based at least in part on a position of the first sensor and a position of the second sensor.

5. The treatment device of claim 1, wherein the controller is configured to provide at least one of the cardiac information and the subject activity and wellness information to a computer server via a network.

6. The treatment device of claim 1, wherein the controller is configured to generate a report based on the cardiac information and the subject activity and wellness information.

7. The treatment device of claim 6, wherein the report suggests a change in at least one of a treatment regimen, an exercise regimen, and a diet regimen.

8. A method of facilitating care of a subject, comprising:

sensing cardiac information of the subject;

sensing subject activity and wellness information of the subject;

receiving quality of life information from the subject;

determining that treatment is to be applied to the subject based upon the cardiac information;

adjusting the treatment based on at least one of the detected subject activity and wellness information and the quality of life information; and

alerting at least one of the subject, a rescuer, a bystander, and a health care provider of a treatment regimen subsequent to sensing the cardiac information; and

applying the treatment to the subject subsequent to alerting at least one of the subject, the rescuer, the bystander, and the health care provider of the treatment regimen.

9. The method of claim 8, comprising:

providing a wearable treatment device including a cardiac sensing electrode, a treatment electrode, a user interface, a sensor; and

a controller;

positioning the cardiac sensing electrode outside the subject;

positioning the treatment electrode outside the subject;

positioning the sensor to detect the subject activity and wellness information of the subject; and

configuring the user interface to receive the quality of life information.

10. The method of claim 8, comprising:

substantially continuously sensing at least one of cardiac information and subject activity and wellness information over a period of time.

11. The method of claim 8, comprising

providing at least one of the cardiac information and the subject activity and wellness information to a computer server via a network.

12. The method of claim 8, comprising:

generating a report based on the cardiac information and the subject activity and wellness information.

13. The method of claim 8, wherein adjusting the treatment comprises:

suggesting a change in at least one of a treatment regimen, an exercise regimen, and a diet regimen.

14. A method of facilitating care of a subject, comprising:

providing a wearable treatment device, the wearable treatment device including a cardiac sensing electrode, a treatment electrode, a user interface configured to receive quality of life information from the subject, a sensor configured to detect subject activity and wellness information indicative of a general wellness of the subject, a controller coupled to the cardiac sensing electrode, the treatment electrode, the user interface, and the sensor, the controller configured to receive the detected cardiac information, the quality of life information, and the detected subject activity and wellness information, to determine that treatment is to be applied to the body of the subject based upon the detected cardiac information, and to adjust the treatment based on at least one of the detected subject activity and wellness information and the quality of life information; and

an alarm module configured to provide an alarm after the cardiac information is detected and before the treatment is applied to the body of the subject.

15. The method of claim 14, comprising:

providing instructions to operate the wearable treatment device, the instructions including at least one instruction to position at least one of the cardiac sensing electrode and the sensor on the subject.

16. The method of claim 14, comprising:

providing instructions to operate the wearable treatment device, the instructions including at least one instruction to position the wearable treatment device on the subject.
