Abstract

The present disclosure relates to a wearable monitor device and methods and systems for using such a device. In certain embodiments, the wearable monitor records cardiac data from a mammal and extracts particular features of interest. These features are then transmitted and used to provide health-related information about the mammal.

Claims

1. A method of monitoring the physiological data of a mammal using a wearable monitor, comprising:

applying a wearable patch to the skin of the mammal, the wearable patch comprising a hardware processer within a first adhesive assembly, the first adhesive assembly comprising a plurality of electrodes configured to detect or derive cardiac signals;

within the hardware processor, continuously storing cardiac signals from the mammal;

wirelessly transmitting the cardiac signals to a computing system;

within the computing system, analyzing the cardiac signals to infer a likelihood of a cardiac arrhythmia originating in the past;

after a period of wear, detaching the wearable patch from the surface of the mammal; and

applying a second adhesive assembly to the skin of the mammal.

2. The method of claim 1, wherein the first adhesive assembly and the second adhesive assembly each comprise a rigid housing and a plurality of flexible wings, each flexible wing comprising an electrode.

3. The method of claim 1, wherein the computing system comprises a gateway.

4. The method of claim 1, wherein the first adhesive assembly and the second adhesive assembly each comprise a battery.

5. The method of claim 1, wherein the first adhesive assembly and the second adhesive assembly each comprise a transmitter, the transmitter configured to wirelessly transmit the cardiac signals to the computing system.

6. The method of claim 1, wherein the period of wear is less than one week.

7. The method of claim 1, wherein the cardiac signals transmitted to the computing system contain about a one hour increment of data.

8. A method of monitoring the physiological data of a mammal using a wearable monitor, comprising:

applying a wearable patch to the skin of the mammal, the wearable patch comprising a hardware processer within a first adhesive assembly, the first adhesive assembly comprising a plurality of electrodes configured to detect or derive cardiac signals;

within the hardware processor, continuously storing cardiac signals from the mammal;

wirelessly transmitting the cardiac signals to a computing system;

analyzing the cardiac signals to infer a likelihood of a cardiac arrhythmia originating in the past;

after a period of wear, detaching the wearable patch from the surface of the mammal;

removing the hardware processor from the wearable patch;

inserting the hardware processor into a second adhesive assembly; and

applying the second adhesive assembly to the skin of the mammal.

9. The method of claim 8, wherein the first adhesive assembly and the second adhesive assembly each comprise a rigid housing and a plurality of flexible wings, each flexible wing comprising an electrode.

10. The method of claim 8, wherein the computing system comprises a gateway.

11. The method of claim 8, further comprising modifying the hardware processor while it is removed from the patch.

12. The method of claim 8, wherein the cardiac signals are transmitted to the computing system on a periodic basis.

13. The method of claim 8, wherein the cardiac signals are continuously transmitted to the computing system.

14. A method of monitoring the physiological data of a mammal using a wearable monitor, comprising:

applying a wearable patch to the skin of the mammal, the wearable patch comprising a hardware processer within a first adhesive assembly, the first adhesive assembly comprising a plurality of electrodes configured to detect or derive cardiac signals;

within the hardware processor, continuously storing cardiac signals from the mammal;

wirelessly transmitting the cardiac signals to a computing system;

analyzing the cardiac signals to infer a likelihood of a cardiac arrhythmia originating in the past;

after a period of wear, detaching the wearable patch from the surface of the mammal; and

applying a second adhesive assembly to the skin of the mammal.

15. The method of claim 14, wherein the first adhesive assembly and the second adhesive assembly each comprise a rigid housing and a plurality of flexible wings, each flexible wing comprising an electrode.

16. The method of claim 14, wherein the computing system comprises a gateway.

17. The method of claim 14, wherein the first adhesive assembly and the second adhesive assembly each comprise a battery.

18. The method of claim 14, wherein the first adhesive assembly and the second adhesive assembly each comprise a transmitter, the transmitter configured to wirelessly transmit the cardiac signals to the computing system.
