Abstract

Wearable (ambulatory) monitors of the present invention have a segmented design, with at least two and preferably three (or more) mechanically independent, spaced apart sensors (e.g., electrodes or other types of physiological sensors) located in discrete islands, or housing structures that are flexibly connected to one another. Each of the sensors is in operable communication with one or more electronics module(s), also located in one or more of the islands. In some embodiments, an electronics module may be centrally located with respect to two or more peripherally located sensors.

Claims

1. A physiological monitor comprising a flexible lower substrate configured for adherence to a skin surface, an upper housing providing, in combination with the lower substrate, a plurality of substantially independent, spaced apart internal volumes, at least one sensor provided in at least one internal volume, and at least one electronics module operably connected to the at least one sensor.

2. The physiological monitor of claim 1, wherein the electronics module is provided in an internal volume separate from the at least one sensor.

3. The physiological monitor of claim 1 having a segmented design in which at least three islands are flexibly connected to one another and comprising at least two sensors.

4. The physiological monitor of claim 3, in which a central island houses the at least one electronics module and at least two peripheral islands house sensors.

5. The physiological monitor of claim 3, in which each of the islands is connected to a neighboring island by means of a narrower flexible portion.

6. The physiological monitor of claim 3, comprising an atrial fibrillation monitor.

7. The physiological monitor of claim 1, wherein the upper housing has a three-dimensional configuration with raised portions providing the internal volumes.

8. The physiological monitor of claim 1, wherein at least one of the plurality of substantially independent, spaced apart internal volumes houses a microprocessor and has a larger internal volume than other volumes housing sensors.

9. The physiological monitor of claim 1, wherein the flexible lower substrate is fabricated from a flexible foam material.

10. The physiological monitor of claim 1, wherein the upper housing has a 3D configuration and is fabricated from flexible foam material.

11. The physiological monitor of claim 1, wherein an external surface of the flexible lower substrate is provided with an adhesive material.

12. The physiological monitor of claim 10, wherein the adhesive material covers only a portion of the external surface of the flexible lower substrate.

13. The physiological monitor of claim 1, wherein a central island is generally rectangular and neighboring, peripheral islands have a generally trapezoidal configuration.

14. The physiological monitor of claim 1, wherein a central island houses processing functions.

15. The physiological monitor of claim 1, additionally comprising a tear-away tab overlying data contacts for retrieval of data.

16. The physiological monitor of claim 1, additionally comprising a switch for switching the monitor on and off.

17. The physiological monitor of claim 1, additionally comprising a moisture ingress sensor provided in at least one of the internal volumes.

18. The physiological monitor of claim 1, wherein the at least one sensor comprises at least one ECG electrode.

19. The physiological monitor of claim 1, additionally comprising a docking receptacle for receiving a re-usable electronics module and/or one or more rechargeable batteries.
