Abstract

A wearable monitoring device is provided. The wearable monitoring device includes a garment to hold an electrode, be worn about a subject, and include an orientation circuit. The monitoring device also includes a control unit coupled to the orientation circuit capable of measuring at least one parameter associated with the orientation circuit and determine whether the electrode is positioned in the garment with the conductive surface oriented towards the subject based on the at least one parameter.

Claims

1. A wearable monitoring device comprising:

a garment to hold an electrode and be worn about a subject, the garment including an orientation circuit, at least a portion of the orientation circuit being integrated into the garment; and

at least one processor operatively coupled to the orientation circuit, the at least one processor configured to measure at least one parameter associated with the orientation circuit and determine whether a conductive surface of the electrode is oriented towards the subject or whether the conductive surface of the electrode is oriented away from the subject based on the at least one parameter.

2. The wearable monitoring device of claim 1, wherein the electrode comprises a therapy electrode for providing a therapeutic shock to the subject.

3. The wearable monitoring device of claim 1, wherein the orientation circuit can be in at least one of an open circuit state corresponding to an incorrect orientation of the electrode and a closed circuit state corresponding to a correct orientation of the electrode.

4. The wearable monitoring device of claim 1, wherein the at least one parameter comprises at least one of a voltage, a current, and a resistance associated with the orientation circuit.

5. The wearable monitoring device of claim 1, wherein the at least one processor determines whether there is an electrical connection between the orientation circuit and the electrode based on the at least one parameter.

6. The wearable monitoring device of claim 5, further comprising an alarm to provide at least one of a visual, audible, or haptic notification to indicate positioning information of the electrode relative to the garment based on the electrical connection.

7. The wearable monitoring device of claim 1, wherein the orientation circuit comprises conductive thread.

8. The wearable monitoring device of claim 1, wherein the orientation circuit comprises a conductive material that provides an electrical path to current flowing through the orientation circuit.

9. The wearable monitoring device of claim 8, comprising conductive snaps disposed between the conductive material and the orientation circuit.

10. The wearable monitoring device of claim 8, wherein the conductive material that provides the electrical path to current flowing through the orientation circuit comprises at least one of one or more conductive threads, one or more wires, and a conductive mesh.

11. The wearable monitoring device of claim 1, wherein the at least one processor is coupled to the electrode and wherein the electrode is configured to sense cardiac activity of the subject.

12. The wearable monitoring device of claim 1, wherein the wearable monitoring device can provide treatment to the subject.

13. The wearable monitoring device of claim 1, further comprising:

at least one pressure sensor included in the garment and operatively coupled to the at least one processor;

wherein the at least one processor is further configured to cause the at least one pressure sensor to measure an amount of pressure and determine whether the electrode is properly positioned on the subject with an appropriate amount of tension to ensure operation of the electrode based on the measured amount of pressure.

14. The wearable monitoring device of claim 13, wherein the at least one pressure sensor comprises one of a spring loaded sensor and a piezoelectric sensor.

15. The wearable monitoring device of claim 13, comprising an alarm to provide at least one of a visual, audible, or haptic notification to indicate positioning information of the wearable monitoring device about the subject based on the measured amount of pressure.

16. The wearable monitoring device of claim 15, wherein the alarm indicates whether the wearable monitoring device is too tight or too loose about the subject.

17. A garment to be worn about a subject comprising:

a pocket to hold an electrode;

an orientation circuit included in the pocket, the orientation circuit configured to provide an indication of an orientation of the electrode relative to the pocket wherein the indication comprises an indication of whether the electrode is positioned in the pocket with a conductive surface of the electrode oriented towards the subject or away from the subject, at least a portion of the orientation circuit being integrated into the pocket; and

at least one conductive material that provides an electrical path to current flowing through the orientation circuit, wherein the at least one conductive material is configured to couple the orientation circuit to at least one processor.

18. The garment of claim 17, wherein the pocket comprises one of a pouch, a sleeve, a slit, or a flap.

19. The garment of claim 17, wherein the pocket comprises at least one of a button, a snap, a hook and loop fastener, a latch, and a zipper to removably secure the electrode in the garment.

20. The garment of claim 17, wherein the pocket comprises a first lateral side proximate to the subject and a second lateral side distal to the subject, and wherein the first lateral side of the pocket comprises conductive mesh.

21. The garment of claim 17, wherein the pocket comprises a first lateral side proximate to the subject and a second lateral side distal to the subject, and wherein the orientation circuit is included in the second lateral side of the pocket.

22. The garment of claim 17, comprising at least one of a belt and a strap to removably secure the garment to the subject.
