Abstract

An electronic device for long-term adhesion to a mammal includes a housing with an electronic component. The electronic device may include a first wing and a second wing, each being integrally formed with the housing. An electrode is positioned on a bottom surface of each of the wings, the electrodes electrically connected to the electronic component. An adhesive layer is provided for adhesion to a surface of the mammal. The adhesive layer may cover a portion of the bottom surfaces of the wings but generally does not cover the electrode or a bottom surface of the housing. A method of applying an electronic device to a mammal includes removing first and second adhesive covers from first and second wings of the electronic device to expose an electrode and an adhesive coated on a bottom surface of each wing.

Claims

1. An electronic device for long-term adhesion to a mammal, the device comprising:

a housing;

a physiologic data collection circuit contained in the housing;

a plurality of wings extending from the housing;

an electrode positioned on a bottom surface of each of the wings, the electrodes electrically connected to the physiologic data collection circuit;

each wing comprising a first adhesive layer positioned on a bottom surface of the wing, wherein the first adhesive layer provides adhesion to the skin of the mammal; and

each wing comprising a second adhesive layer functioning as an adhesion guard protecting the first adhesive layer;

the second adhesive layer positioned over a top of the wing and extending horizontally outward beyond a boundary of each wing.

2. The device of claim 1, wherein the first adhesive layer is not on a bottom surface of the housing.

3. The electronic device of claim 1, wherein the wings are more flexible than the housing.

4. The electronic device of claim 1, wherein the wings and the housing are made from the same material.

5. The electronic device of claim 1, wherein the wings and the housing are made from different materials.

6. The electronic device of claim 1, further comprising a hinge portion adjacent the housing.

7. The electronic device of claim 1, further comprising a flap connected to each wing, the flaps extending below the housing but not directly attached to a bottom surface of the housing, wherein the first adhesive layer extends onto a bottom surface of each flap.

8. The electronic device of claim 7, further comprising a connector segment configured to connect the flaps together without directly attaching to the bottom surface of the housing.

9. The electronic device of claim 1, wherein the first adhesive layer comprises an adhesive that can absorb fluids.

10. The electronic device of claim 1, wherein the first adhesive layer comprises a hydrocolloid adhesive.

11. The electronic device of claim 1, wherein the first adhesive layer comprises a pressure-sensitive adhesive.

12. The electronic device of claim 11, wherein the pressure sensitive adhesive is selected from the group consisting of a polyacrylate, a polyisobutylene and a polysiloxane.

13. The electronic device of claim 1, further comprising;

an additional adhesive layer between each wing and the first adhesive layer; and

a synthetic material layer between the wing and the first adhesive layer.

14. The electronic device of claim 1, wherein the physiologic data collection circuit is configured to collect cardiac rhythm data from the mammal.

15. The electronic device of claim 1, wherein each wing comprises a fabric or synthetic fiber layer.

16. The electronic device of claim 15, wherein the fabric or synthetic fiber layer is positioned over the first adhesive layer.

17. The electronic device of claim 1, further comprising a third adhesive layer positioned between the first adhesive layer and the second adhesive layer.

18. The electronic device of claim 1, wherein the second adhesive layer covers the entirety of the wing.

19. A device for monitoring cardiac rhythms of a mammal, the device comprising:

a floating section configured to move toward and away from the body of a mammal;

two skin-adhering sections extending out from the floating section;

an electrode integral with a bottom surface of each skin-adhering section and disposed along the bottom surface of each skin-adhering section;

each skin-adhering section comprising a first adhesive layer on the bottom surface of the skin-adhering section, wherein the first adhesive layer provides adhesion to the skin of the mammal; and

each skin-adhering section comprising a second adhesive layer functioning as an adhesion guard protecting the first adhesive layer, the second adhesive layer positioned over a top of the skin-adhering section and extending horizontally outward beyond a boundary of each skin-adhering section.
