Embodiment 1
[0028] According to the sleep apnea monitoring method of the embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0029] Step S101, collecting sound signals in the environment through a recording device.
[0030] Step S102, using the first model to analyze the sound signal to determine the number of respiratory events.
[0031] Wherein, the respiratory event is that the silent duration between two adjacent breaths is greater than the first preset duration (that is, when the silent duration between two adjacent breaths is greater than the first preset duration, it is determined that the Respiratory events), the first model is trained by machine learning using multiple sets of data, each set of data in the multiple sets of data includes: a sound signal and a respiratory event identified in the sound signal.
[0032] Optionally, the analyzing the sound signal by using the first model, and determining the number of respirator...
Embodiment 2
[0062] Sleep breathing monitoring device according to an embodiment of the present invention, such as Figure 4 shown, including:
[0063] Recording device 40, used for collecting sound signals in the environment;
[0064] A signal processing unit 41, connected to the recording device 40, configured to use the first model to analyze the sound signal to determine the number of respiratory events, wherein the respiratory event refers to the silence between two adjacent breaths The duration is longer than a first preset duration, and the first model is trained by machine learning using multiple sets of data, each set of data in the multiple sets of data includes: a sound signal and a respiratory event identified in the sound signal;
[0065] The analysis and judgment unit 42 is connected to the signal processing unit 41 and configured to determine a breathing detection result according to the number of the breathing events, wherein the breathing detection result is used to indic...

Abstract
The present invention provides a sleep breathing monitoring method and device, the method comprising: collecting sound signals in the environment through a recording device; using a first model to analyze the sound signals to determine the number of breathing events, wherein the breathing events are The silence duration between two adjacent breaths is longer than the first preset duration. The first model is trained by using multiple sets of data through machine learning, and each set of data in the multiple sets of data includes: the sound signal and the recognition in the sound signal The respiratory events are detected; according to the number of respiratory events, the respiratory detection result is determined, wherein the respiratory detection result is used to indicate the respiratory disturbance index AHI. Therefore, the patient's audio data can be directly collected, analyzed and judged during the patient's sleep, and the corresponding breathing detection results can be obtained, which can effectively improve the efficiency of the assessment of the patient's sleep quality, and solve the problem of sleep quality assessment of the patient in the prior art. problem of low efficiency.
Description
technical field [0001] The field of medical equipment of the present invention, in particular, relates to a method and device for monitoring sleep respiration. Background technique [0002] Sleep quality is an important factor affecting people's health. There are more and more people with poor sleep quality at present. Patients with poor sleep quality have sleep apnea or hypopnea, and the sleep quality can be evaluated by analyzing the sleep apnea or hypopnea of the patients. [0003] At present, when evaluating a patient's sleep quality, first use a corresponding recording device to record the audio data during the patient's sleep, and then input the audio data into a special analysis software for analysis to get the result. Not only the work efficiency Low, and time-consuming and labor-intensive. Contents of the invention [0004] The main purpose of the present invention is to provide a sleep breathing monitoring method and device to solve the problem of low effici...
