Problems solved by technology

[0005] However, since most of the environmental noise is a high-frequency signal, it cannot be eliminated after high-pass filtering, and it will still be mixed in the oscillating signal
The existing scheme calculates each oscillation separately, and cannot recognize this kind of noise. The noise will be included in the calculation, which will cause misidentification of snoring
In addition, the existing scheme has to score and accumulate each qualified oscillation amplitude, which increases the calculation amount and complexity of the device

Abstract

The invention discloses a snoring detection method, a snoring detection device and a positive pressure breathing machine. The snoring sound detection method includes the following steps: obtaining a high-frequency signal corresponding to a snoring event range in a breathing signal of a current breathing process; converting the high-frequency signal into a low-frequency signal; judging that the low-frequency signal Whether the value of is greater than the preset threshold; if so, it is determined that a snoring event occurs in the current breathing process. The snoring sound detection solution of the present invention converts high-frequency signals into relatively slow-changing low-frequency signals, which can reduce the influence of noise on snoring sound recognition and improve the accuracy of snoring sound recognition.

Description

technical field [0001] The invention relates to ventilator technology, in particular to a snoring sound detection method, a snoring sound detection device, and a positive pressure ventilator. Background technique [0002] Snoring is a common sleep disorder. Mild snoring has little impact on human health, but some snoring patients also have varying degrees of breath holding during sleep, that is, snoring accompanied by sleep apnea, which can lead to varying degrees of hypoxia and damage the patient's health. [0003] Snoring occurs when the airways are narrowed or slightly blocked causing poor airflow. Using a non-invasive positive pressure breathing machine (Continuous Positive Airway Pressure, continuous positive airway pressure) to treat snoring or sleep apnea syndrome is a common method. During the treatment process, snoring data (mainly the number of times of snoring) is an important basis for judging the therapeutic effect. When using an automatic pressure-regulating...
