Abstract

The present invention relates to a physiological monitoring device. Some embodiments of the invention allow for long-term monitoring of physiological signals. Further embodiments may also allow for the monitoring of secondary signals such as motion.

Claims

1. An electronic device for monitoring physiological signals in a mammal, the device comprising:

a plurality of wings extending laterally from a housing, each flexible wing configured to conform to a surface of the mammal and comprising a lower substrate layer, an upper substrate layer, and a bottom surface comprising a long-term adhesive, the long-term adhesive configured to adhere to the skin of the mammal;

a hardware processor housed within the housing;

a flexible electrode positioned on each flexible wing, each flexible electrode configured to provide conformal contact with a non-planar surface of the skin of the mammal during movement of the mammal;

an electrode trace positioned between each upper substrate layer and each lower substrate layer, each upper substrate layer comprising a rim extending horizontally outward beyond the corresponding lower substrate layer, the rim being thinner in a vertical plane than an adjacent portion of the flexible wing and configured to reduce edge-lift of the flexible wing from the skin of the mammal; and

wherein each electrode trace extends outward from the housing, each flexible electrode and at least a portion of each electrode trace configured to remain conformal with the skin of the mammal during bending of the skin.

2. The electronic device of claim 1, wherein each electrode trace conforms to an entire upper surface of each corresponding flexible electrode.

3. The electronic device of claim 1, wherein the electrode traces comprise a first material and the flexible electrodes comprise a second material, the first material different from the second material.

4. The electronic device of claim 1, wherein the housing comprises a patient trigger configured to depress and initiate recordation of an instance in time of a perceived cardiac event.

5. The electronic device of claim 1, wherein the housing comprises an upper housing member and a lower housing member, the upper housing member configured to detachably connect to the lower housing member.

6. The electronic device of claim 5, further comprising an upper gasket and a lower gasket positioned between the upper housing member and the lower housing member.

7. The electronic device of claim 2, wherein the long-term adhesive is a hydrocolloid.

8. The electronic device of claim 1, further comprising a tab extending from the housing and positioned over each electrode trace, each tab configured to provide strain relief to the corresponding electrode trace.

9. The electronic device of claim 8, wherein each tab extends partially along the length of each corresponding electrode trace.
