Electrocardiography patch
An electrocardiography patch is provided. A backing includes an elongated strip with a midsection connecting two rounded ends. The midsection tapers in from each end and is narrower than each of the two ends. An electrode is positioned on each end of the backing on a contact surface to capture electrocardiographic signals. A circuit trace electrically is coupled to each of the electrodes in the pair. A battery is provided on an outer surface of the backing opposite the contact surface. Memory is provided on the outer surface of the backing to store data regarding the electrocardiographic signals. A processor is powered by the battery to write the data into the memory.
1. An electrocardiography patch, comprising:
a backing comprising an elongated strip with a substantially straight midsection connecting only two rounded ends, wherein the midsection tapers in from a center of each end, is narrower than each of the two ends, and sides of the two rounded ends extend past sides of the midsection;
a single electrode positioned on each of a proximal end and a distal end of the backing on a contact surface to capture electrocardiographic signals, wherein both of the electrodes and the midsection are positioned along a common axis with each of the electrodes on opposite ends of the midsection;
a pair of circuit traces, each circuit trace electrically coupled to one of the electrodes in the pair and at least one of the circuit traces positioned along the midsection;
a battery provided on an outer surface of the backing opposite the contact surface and along the common axis of the midsection and the electrodes;
memory provided above the outer surface of the backing to store data regarding the electrocardiographic signals; and
a processor powered by the battery to write the data into the memory and positioned on one of the rounded ends adjacent to the electrode on that end; and
a compartment configured to house the battery separate from a different compartment of the processor, wherein the different compartment overlays the electrode on the rounded end on which the processor is positioned and the compartment is formed within a non-conductive receptacle and located with the battery along the common axis of the substantially straight midsection and the electrodes, on one of the rounded ends prior to that rounded end tapering in to the midsection that terminates at the other rounded end.
