Non-contact type sleep stage classification and sleep breathing disorder detection method

Abstract

The invention discloses a non-contact type sleep stage classification and sleep breathing disorder detection method. The non-contact type sleep stage classification and sleep breathing disorder detection method includes the detection steps that 1, when a person is detected, the detected person lies in bed, antennae of a wireless reception and transmission machine are arranged right above the detected person or askew above the detected person, and a reception antenna and a transmitting antenna are arranged in parallel; 2, the wireless reception and transmission machine performs digital signal processing and mode recognition on received signals, and finally records and reports disorder time. Wireless signals transmitted by using the non-contact type sleep stage classification and sleep breathing disorder detection method are low in power, within 20mw, and harmless to human bodies. Due to the fact that non-contact type measurement is used in the non-contact type sleep stage classification and sleep breathing disorder detection method, the non-contact type sleep stage classification and sleep breathing disorder detection method is convenient to use, and facilitates long time dynamic monitoring and testing.

Description

technical field [0001] The invention relates to a non-contact sleep staging and sleep-disordered breathing detection method, in particular to a non-contact sleep staging and sleep-disordered breathing detection method based on the monitoring of breathing rate, breathing amplitude and heart rate variability. Background technique [0002] Sleep apnea syndrome is a common disease that seriously endangers health. The main onset groups are middle-aged men over 40 years old and elderly people over 60 years old. Sleep apnea syndrome is characterized by more than 30 episodes of apnea or hypopnea during a daily 7-hour sleep cycle, or more than 5 episodes of both breathing disorders within an hour. An apnea event is defined as the absence of airflow through the airway for 10 consecutive seconds during sleep. A hypopneic event is defined as a sleep state in which the flow rate of respiratory airflow or amplitude of respiratory movement in the thorax and abdomen is less than 50% of t...

Problems solved by technology

Traditional testing and diagnostic methods require the use of a variety of testing instruments at the same time, which is inconvenient to use on some occasions, and patients who are not used to the initial test are not used to it, which will affect the test results. In addition, this method is not convenient for repeated use. Multi-day long-term monitoring
