The system of the present invention is intended to provide a simple, out-of-clinic sleep disorders testing tool. It can be used for pretest screening and diagnosis, and post therapy follow-up of patients. The hardware component comprises a disposable sensor pack containing a PVDF airflow sensor and a PVDF pulse wave sensor, each of which is permanently connected to a signal conditioning and communications module configured to communicate with a patient's smartphone via a Bluetooth circuit. An APP stored in the smartphone allows a patient to initiate a diagnostic recording, collect and store digitized data onto the phone and, subsequently, upload data to a secure server for analysis on a host computer following completion of the test.

Combination airflow, sound and pulse wave sensor pack with smartphone data aquisition and transfer

A multi sensor module especially designed for use in sleep-study applications includes a PVDF film piezoelectric transducer enclosed between an upper layer of a single-sided adhesive tape strip and a lower layer of a double-sided adhesive tape strip. Also adhesively affixed to the upper single-sided adhesive tape strip, but not overlaid by the lower double-sided adhesive tape strip are first and second conductive electrodes. The combination sensor module is adapted to be adhesively affixed to the chest area of a person and further included in an extension of the PVDF strip that is adapted to overlay the suprasternal notch of a person for producing signals responsive to respiratory activity of the person.

Combination physiologic sensor

System for storing pre-packaged sleep related sensors and facilitating effective, efficient, or error-free usage of the sleep related sensors for sleep diagnostic testing including a thoracic respiratory effort belt, an abdominal effort belt, an oxygen saturation sensor, and a nasal and oral airflow sensor, a receptacle for storing sleep-related sensors, and instruction for using the sleep-related sensors.
