Extended Wear Ambulatory Electrocardiography And Physiological Sensor Monitor
First Claim
1. An extended wear electrocardiography and physiological sensor monitor recorder, comprising:
- a sealed housing adapted to be removably secured into a non-conductive receptacle on a disposable extended wear electrode patch; and
an electronic circuitry comprised within the sealed housing, comprising;
an externally-powered micro-controller operable to execute under micro programmable control through firmware that is stored in a program memory unit of the micro-controller;
an electrocardiographic front end circuit electrically interfaced to the micro-controller and operable to sense electrocardiographic signals through electrocardiographic electrodes provided on the disposable extended wear electrode patch, each of the electrocardiographic electrodes adapted to be positioned axially along the midline of the sternum for capturing action potential propagation; and
an externally-powered flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals.

Abstract
Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally (in the midline) on the patient'"'"'s chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. Instead, the patient can place an electrode patch anywhere within the general region of the sternum. Power is provided through a battery provided on the electrode patch, which avoids having to open the monitor recorder'"'"'s housing for battery replacement.

8. An extended wear electrocardiography and physiological sensor monitor, comprising:
-
a disposable extended wear electrode patch comprising; a flexible backing formed of an elongated strip of stretchable material with a narrow longitudinal midsection and, on each end, a contact surface at least partially coated with an adhesive dressing provided as a crimp relief; a pair of electrocardiographic electrodes conductively exposed on the contact surface of each end of the elongated strip, respectively; a non-conductive receptacle adhered to an outward-facing surface of the elongated strip and comprising a plurality of electrical pads; and a flexible circuit affixed on each end of the elongated strip as a strain relief and comprising a pair of circuit traces electrically coupled to the pair of the electrocardiographic electrodes and a pair of the electrical pads, at least one of the circuit traces adapted to extend along the narrow longitudinal midsection to serve as the strain relief; and a reusable electrocardiography monitor having a sealed housing adapted to be removably secured into the non-conductive receptacle and comprising; a micro-controller operable to execute under micro programmable control through firmware that is stored in a program memory unit of the micro-controller, the micro-controller electrically interfaced to an electrocardiographic front end circuit that is operable to sense electrocardiographic signals through the electrocardiographic electrodes via the pair of the electrical pads; and a flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 24, 25, 26)
