Abstract

A wearable therapeutic device is provided. The wearable therapeutic device includes a garment, and the garment includes an electrode and a conductive thread. A control unit is coupled to the conductive thread and identifies an electrical connection between a conductive surface of the electrode and the conductive thread, and an alarm module can provide information about the positioning of the electrode in the garment based on the electrical connection.

Claims

1. A wearable therapeutic device, comprising:

a garment configured to include an electrode;

a conductive thread included in at least part of the garment;

a control unit coupled to the conductive thread and configured to identify an electrical connection between a conductive surface of the electrode and the conductive thread and determine whether the electrode is positioned in the garment with the conductive surface facing towards a subject wearing the wearable therapeutic device based on the electrical connection; and

an alarm module configured to indicate positioning information of the electrode in the garment based on the electrical connection.

2. The wearable therapeutic device of claim 1, wherein the garment includes a pocket configured to house the electrode, the pocket having a first lateral side and a second lateral side;

and

wherein the conductive thread is integrated into one of the first lateral side and the second lateral side of the pocket.

3. The wearable therapeutic device of claim 1, wherein the alarm module indicates improper positioning of the electrode, and wherein the garment includes a pocket configured to house the electrode, the pocket having a first lateral side that includes a conductive mesh and a second lateral side that includes the conductive thread.

4. The wearable therapeutic device of claim 3, further comprising:

a conductive element included in the garment;

wherein the control unit is further configured to detect a current path that includes the conductive thread, the conductive surface of the electrode, and the conductive element.

5. The wearable therapeutic device of claim 4, wherein the alarm module is configured to notify at least one of the subject wearing the wearable therapeutic device and a health care provider that the electrode is improperly positioned.

6. The wearable therapeutic device of claim 4, further comprising:

a monitor configured to display an indication that the electrode is improperly positioned.

7. The wearable therapeutic device of claim 1, wherein the alarm module is configured to notify at least one of the subject wearing the wearable therapeutic device and a health care provider that the electrode is improperly positioned.

8. The wearable therapeutic device of claim 1, further comprising:

a monitor configured to display an indication that the electrode is improperly positioned.

9. The wearable therapeutic device of claim 1, wherein the garment includes a pocket configured to house the electrode, the pocket having a first lateral side proximate to the subject and a second lateral side distal to the subject, and wherein the conductive thread is disposed in the second lateral side of the pocket.

10. The wearable therapeutic device of claim 1, further comprising:

a conductive element included in the garment; and

a connector configured to couple the conductive thread with the conductive element.

11. The wearable therapeutic device of claim 1, wherein the garment includes a belt, the wearable therapeutic device further comprising:

a conductive element included in the belt; and

a connector configured to couple the conductive thread with the conductive element to form electrical connection between the conductive surface of the electrode and the conductive element.

12. The wearable therapeutic device of claim 11, wherein the connector includes a snap.

13. The wearable therapeutic device of claim 1, wherein the conductive thread forms a stitched pattern in the garment.

14. The wearable therapeutic device of claim 1, wherein the conductive thread forms a stitched pattern including at least two substantially parallel stitched lines.

15. The wearable therapeutic device of claim 1, wherein the conductive thread forms a pattern including at least one of a quadrilateral shape, a polygonal shape, an oblong shape, a circular shape, an oval shape, a round shape, and a triangular shape.

16. The wearable therapeutic device of claim 1, wherein the conductive thread forms part of an electrical connection with the electrode.

17. The wearable therapeutic device of claim 1, wherein the conductive surface of the electrode includes a first portion and a second portion separated by an insulating gap.

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

providing a wearable therapeutic device that includes an electrode and a conductive thread;

identifying an electrical connection between a conductive surface of the electrode and the conductive thread;

determining whether the electrode is positioned in the wearable therapeutic device with the conductive surface facing towards the subject wearing the wearable therapeutic device based on the electrical connection; and

providing a notification to indicate positioning information of the electrode based on the electrical connection.

19. The method of claim 18, wherein the wearable therapeutic device includes a garment, the method further comprising:

removably housing the electrode in a pocket of the garment and proximate to the conductive thread.

20. The method of claim 18, further comprising:

determining that the electrode is positioned with a conductive surface of the electrode facing away from the subject.

21. The method of claim 20, further comprising:

detecting a closed circuit that includes a conductive surface of the electrode and the conductive thread; and

determining that the electrode is improperly positioned.

22. The method of claim 18, wherein the wearable therapeutic device includes a garment having a conductive element, the method further comprising:

detecting a current path between the conductive thread, the conductive surface of the electrode, and the conductive element.

23. The method of claim 22, further comprising:

electrically coupling the conductive thread with the conductive element.
