Abstract: A muscle activity monitoring system that integrates a minimal data-collection and analysis system into a disposable, single-use device that achieves data collection and analysis without requiring the assistance of a trained technician. The monitoring system includes a muscle activity sensor for sensing muscle activity at a location on the body, and a processor for analyzing the sensed muscle activity to determine a presence of a pattern of muscle activity that is correlated to a diagnosis. The diagnosis is displayed by a plurality of non-volatile markers. The markers are preferably heat-sensitive or electrochemical cells that undergo a permanent detectable change when a current flows through the cells. A housing houses the processor, the display, and a power source on the muscle activity sensor.

Abstract: This invention is a method, and device, suitable for use without professional medical supervision, for screening for sleep apnea. All elements of the device are housed in a small, flexible, plastic housing which is placed on the user's philtrum. A thermistor acquires data describing the respiratory pattern. A processor analyzes the respiratory pattern in real time and outputs a study result, describing the occurrence of any episodes of apnea, to a non-volatile colored marker on the plastic housing. A flashing LED display informs the user when placement of the device is appropriate. A lithium battery, which powers all elements of the device, is activated by a pull-tab removed by the user.
