Device features and design elements for long-term adhesion
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.
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.
