Self-contained personal air flow sensing monitor

摘要

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. The monitor further includes sensors for monitoring patient's air flow and respiratory measures contemporaneously with the ECG monitoring.

主权项

1. A self-contained personal air flow sensing 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 and electrically interfaced to one or more respiratory sensors comprising an air flow sensor and at least one of an SpO2 sensor, a pCO2 sensor, and a respiratory rate sensor, the one or more respiratory sensors comprised within at least one of the disposable extended wear electrode patch and the sealed housing;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; andan externally-powered flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals and respiratory events comprising physiological events detected by the respiratory sensors.
