Physiological monitoring device
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.
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.
