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 and treatment device comprising:

a garment configured to hold at least one therapy electrode and be worn about a patient, the garment comprising circuitry, at least a portion of such circuitry being integrated into the garment; and

at least one processor operatively coupled to the circuitry, the at least one processor configured to

measure at least one parameter associated with the circuitry included in the garment, and

determine, based on the at least one parameter, whether a conductive surface of the at least one therapy electrode is positioned on the patient to apply therapy to the patient, and

cause, responsive to determining that the conductive surface of the at least one therapy electrode is not positioned on the patient so as to apply the therapy to the patient, an alarm to instruct the patient to at least one of

tighten the garment, and

reposition the at least one therapy electrode so that the conductive surface of the at least one therapy electrode is positioned to apply the therapy to the patient,

wherein the at least one processor is further configured to cause the alarm to provide a warning that the therapy will be applied within a time period.

2. The wearable monitoring and treatment device of claim 1, wherein the at least one processor is configured to cause the alarm to provide at least one of a visual, audible, or haptic notification to indicate positioning information of the wearable monitoring and treatment device about the patient.

3. The wearable monitoring and treatment 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 circuitry.

4. The wearable monitoring and treatment device of claim 1, wherein the at least one therapy electrode comprises a perforated conductive material.

5. The wearable monitoring and treatment device of claim 1, wherein the garment includes a pocket configured to house the at least one therapy electrode, the pocket having a first lateral side and a second lateral side;

and

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

6. The wearable monitoring and treatment device of claim 5, wherein the pocket comprises one of a pouch, a sleeve, a slit, or a flap.

7. The wearable monitoring and treatment device of claim 1, further comprising at least one of a belt and a strap to removably secure the garment to the patient.

8. The wearable monitoring and treatment device of claim 1, wherein the at least one processor is further configured to cause the alarm to notify a health care provider that the at least one therapy electrode is improperly positioned.

9. The wearable monitoring and treatment device of claim 1, further comprising:

a monitor operatively coupled to the at least one processor and configured to display an indication that the at least one therapy electrode is improperly positioned.

10. The wearable monitoring and treatment device of claim 1, further comprising ECG sensing electrodes configured to sense ECG activity of the patient'"'"'s heart.

11. The wearable monitoring and treatment device of claim 10, wherein the at least one processor is further configured to

analyze the ECG activity;

and

cause the alarm to provide a warning that the patient is in danger of experiencing cardiac arrest responsive to detecting a cardiac arrhythmia event based on the ECG activity.

12. The wearable monitoring and treatment device of claim 11, wherein the at least one processor is further configured to cause the alarm to provide a notification that the at least one therapy electrode is properly positioned.

13. The wearable monitoring and treatment device of claim 1, wherein the at least one processor is further configured to cause the alarm to alert the patient that the at least one therapy electrode is not flush with the patient.

14. The wearable monitoring and treatment device of claim 1, wherein the at least one processor is further configured to cause the alarm to instruct the patient to tighten the garment responsive to at least one of movement of the garment and expansion of the garment.

15. The wearable monitoring and treatment device of claim 1, wherein the at least one processor is further configured to cause the alarm to instruct the patient to reposition the garment.

16. The wearable monitoring and treatment device of claim 1, further comprising a monitor operatively coupled to the at least one processor, wherein the at least one processor is configured to cause the alarm to be provided by the monitor.

17. A wearable monitoring and treatment device comprising:

a garment configured to hold at least one therapy electrode and be worn about a patient, the garment comprising circuitry, at least a portion of such circuitry being integrated into the garment;

an alarm; and

at least one processor operatively coupled to the circuitry, the at least one processor configured to

measure at least one parameter associated with the circuitry included in the garment, and

determine, based on the at least one parameter, whether a conductive surface of the at least one therapy electrode is positioned on the patient to apply therapy to the patient, and

cause, responsive to determining that the conductive surface of the at least one therapy electrode is not positioned on the patient so as to apply the therapy to the patient, an alarm to instruct the patient to at least one of

tighten the garment, and

reposition the at least one therapy electrode so that the conductive surface of the at least one therapy electrode is positioned to apply the therapy to the patient,

wherein the at least one processor is further configured to cause the alarm to instruct the patient to tighten the garment responsive to at least one of movement of the garment and expansion of the garment.
