The invention discloses an obstructive sleep apnea-hypopnea syndrome (OSAHS) patient preliminary screening system. The preliminary screening system comprises a singlechip microcomputer, a computer, a mouth-nose airflow monitoring module, a thoracoabdominal respiratory movement monitoring module and a blood oxygen and heart rate monitoring module, wherein the mouth-nose airflow monitoring module, the thoracoabdominal respiratory movement monitoring module and the blood oxygen and heart rate monitoring module are connected with the singlechip microcomputer in a wired or wireless manner; and the singlechip microcomputer is connected with the computer in the wired or wireless manner. A sleep monitoring system comprises three core sleep monitoring modules of mouth-nose airflow monitoring, thoracoabdominal respiratory movement monitoring and blood oxygen and heart rate monitoring and is utilized to preliminarily screen out OSAHS patients from sleep breathing disorder diseases, on the one hand, more scientific monitoring data is obtained, and on the other hand, the number of sensors on patients can be reduced to the maximum extent; and moreover, the system monitors the patients in natural sleep states at home, and the obtained data is relatively in accordance with the practical sleep states of the patients in daily lives. Particularly, after a video / audio module is arranged, the preliminary screening system can more vividly show the apnea and labored breathing symptoms of the sleeping patients, and warns the patients to get treatment in a specialized sleep hospital in time.

The invention discloses an intelligent sleep monitoring system which comprises a sleep monitoring magnetic snap and a sleep management terminal. The sleep monitoring magnetic snap and the sleep management terminal are connected with each other through Bluetooth or WIFI; the sleep monitoring magnetic snap is provided with a shell, and a body movement monitoring sensing unit, a signal collecting unit, a central processing unit and a data transmission unit are installed in the shell and are electrically connected with one another. The sleep monitoring magnetic snap and the sleep management terminal are designed, a three-axis acceleration sensor based on the MEMS technology is arranged in the sleep monitoring magnetic snap, and thus the change of body movement information and body position information during sleep of a user is sensed. A calculation model associated with sleep state related indexes is obtained according to the analysis of massive test data; the sleep management terminal detects the body movement state of the user (whether the user turns over or gets up or leaves a bed or the like) based on software, estimates the sleep state of the user (deep sleep or light sleep or no sleep) and the duration of each sleep state and provides a sleep score and a sleep report.

What is disclosed is a system and method for estimating minute ventilation by analyzing distortions in reflections of structured illumination patterns captured in a video of a thoracic region of a subject of interest being monitored for respiratory function. Measurement readings can be acquired in a few seconds under a diverse set of lighting conditions and provide a non-contact approach to patient respiratory function that is particularly useful for infant care in an intensive care unit (ICU), sleep studies, and can aid in the early detection of sudden deterioration of physiological conditions due to detectable changes in patient chest volume. The systems and methods disclosed herein provide an effective tool for minute ventilation estimation and respiratory function study and analysis in a non-contact remote sensing environment.

The present invention comprises methods for detecting, assessing, diagnosing, and pre-diagnosing sleep apnea, and for assessing the efficacy of a treatment for sleep apnea. Methods for the detection, assessment, diagnosis and pre-diagnosis (screening) of sleep apnea and the assessment of a treatment for sleep apnea according to the present invention may be performed in the absence of a sleep study. The patients subject to these methods may remain awake during their performance. The invention may be applied to other vascular conditions besides sleep apnea, wherein the sleep apnea methods described herein are example methods for the application of the present invention to the detection, assessment, diagnosis and pre-diagnosis (screening) of other vascular conditions.

Methods for diagnosing sleep apnea are provided herein. In at least one example, a method may be provided including receiving airway image data from a remote end imaging sensor coupled to a nasal tube disposed within an upper airway above a constriction point, and analyzing the airway image data and displaying in a sleep study report the airway image data to identify airway closures related to obstructive sleep apnea.

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.

The invention discloses a portable sleep monitoring system based on ear EEG. The system comprises two ear-hanging electrode modules, an EEG acquisition module, a mobile terminal module and an analysis module, wherein the two ear-hanging electrode modules are arranged on two ears, and each ear-hanging electrode module comprises a plurality of acquisition electrodes and a reference electrode; the EEG acquisition module is connected with the ear-hanging electrode modules and used for acquiring EEG signals from the acquisition electrodes and the reference electrodes and performing preliminary signal processing to obtain processed ear EEG signals; the mobile terminal module is used for receiving the processed ear EEG signals, displaying waveforms in real time and transmitting the ear EEG signals to the analysis module after acquisition is completed; the analysis module performs sleep stage division and characteristic wave detection on the ear EEG signals and generates a sleep analysis report. The sleep monitoring system adopts ear-hanging electrodes, can be worn autonomously, is portable and high in fitting degree and has higher sensitivity and accuracy.
