Embodiment Construction
[0022] Such as figure 1 As shown, a kind of apnea detection system based on the method of the present invention includes an electromagnetic wave detection module for collecting the respiratory signal of the subject, a breathing detection module for receiving the respiratory signal and detecting whether the apnea is apnea, and a respiration detection module for detecting the apnea An alarm module that issues a warning, the electromagnetic wave detection module is connected to the breathing detection module, and the breathing detection module is connected to the alarm module.
[0023] In a specific embodiment of the present invention, the electromagnetic wave detection module is a continuous wave life detector, which is used to collect the respiratory signal of the subject to be tested; the respiratory detection module is a PC, which is used to receive the respiratory signal and detect whether the breathing is suspended, and trigger the alarm module when the breathing is suspende...

The invention discloses a detection method of an apnea detection system. The detection method comprises the steps that an electromagnetic wave detection module acquires respiration signals of a to-be-detected person and transmits the respiration signals to a respiration detection module; the respiration detection module obtains the respiration signals acquired by the electromagnetic wave detection module, analyzes the respiration signals and determines whether apnea occurs, and triggers an alarm module to give an alarm when the apnea occurs; and the alarm module gives an alarm when triggered by the respiration detection module. The electromagnetic waves emitted by the electromagnetic wave detection module can penetrate nonmetal medium to detect the respiration signals, detection can be carried out without directly contacting a human body, and the to-be-detected person is not required to be restricted. Time frequency analysis can be performed on the respiration signals on basis of time frequency analysis and spectrum analysis technologies by utilization of periodicity of the respiration signals, Doppler instantaneous frequency of respiration is estimated, whether the Doppler instantaneous frequency of respiration is periodic is determined, and therefore whether the to-be-detected person is breathing is determined, calculating amount is small, and detection speed is fast.
Description
technical field [0001] The invention relates to the technical field of respiration detection, in particular to a detection method of an apnea detection system, which is mainly used for the detection of vital respiration arrest of critically ill patients, infants and disaster rescuers. Background technique [0002] During sleep, the complete cessation of oronasal airflow for more than 10 seconds is considered apnea. When sleep apnea occurs, there is less oxygen in the blood and the body is starved of oxygen. If this phenomenon occurs frequently, that is, more than 5 times per hour or more than 30 times of pauses during sleep in 7 hours, if the phenomenon of apnea is not found for many years and is not treated effectively, it will cause serious consequences, and a serious problem may occur. A series of pathological and physiological changes. Therefore, monitoring sleep apnea is essential to pay attention to human health. [0003] PSG and wrist actigraphy are commonly used t...
