Embodiment 1

[0078] Such as figure 1 As shown, it is a schematic flowchart of a method for monitoring sleep apnea provided by Embodiment 1 of the present invention. The method can be described as follows.

[0079] Step 101: Obtain sound information collected during a sleep cycle of the patient.

[0080] Wherein, the sound information includes noise information and snore information.

[0081] In step 101, in the daily sleep scene, the sound information that can be generated mainly includes: sound information related to breathing (for example: snoring sound information and rough breathing sound information); sound information unrelated to breathing (for example: air conditioner The sound information emitted by the vehicle, the sound information emitted by the fan, the sound information emitted by the car horn, the sound information emitted by the collision of objects, etc.).

[0082] Then, when the sound information generated in a sleep cycle of the patient is collected, what is collected...

Embodiment 2

[0121] Such as figure 2 As shown, it is a schematic structural diagram of monitoring sleep apnea provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is an invention under the same inventive concept as Embodiment 1 of the present invention. The device includes: an acquisition module 11. Distinguishing module 12 and monitoring module 13, wherein:

[0122] An acquisition module 11, configured to acquire sound information collected during a sleep cycle of the patient; and

[0123] A distinguishing module 12, configured to identify the collected sound information, and distinguish the patient's snoring information contained in the sound information;

[0124] The monitoring module 13 is configured to determine the sleep apnea occurring in one sleep cycle of the patient according to the snoring sound information.

[0125] The sound information includes noise information;

[0126] The distinguishing module 12 is specifically used to divide the c...

Abstract

The invention discloses a method and equipment for monitoring sleep apnea. The method comprises the following steps: obtaining sound information collected in a sleeping period of a patient; identifying the collected sound information and distinguishing snore information of the patient in the sound information; determining the sleep apnea in a sleeping period of the patient according to the snore information; and determining the snore information sent in one sleeping period of the patient by analyzing the sound information collected in one sleeping period of the patient, so as to determine the sleep apnea in the sleeping period of the patient according to the snore information. The problem that background noises and burst noises in a sleep scene are greatly overlapped with snore signals on a time-frequency domain when a manner of judging the apnea by analyzing snores is adopted so that the snore signal cannot be accurately monitored is solved, and the apnea monitoring precision is effectively improved.

Description

technical field [0001] The invention relates to the technical field of physiological characteristic data processing, in particular to a method and equipment for monitoring sleep apnea. Background technique [0002] Studies have found that during sleep, respiratory airflow stops due to obstruction and other reasons (that is, breathing stops during sleep), and the duration of respiratory airflow cessation exceeds 10 seconds or the air flow is lower than 20% of normal, which is regarded as sleep apnea. pause. [0003] Assuming that during the 7 hours of sleep time per night, the number of repeated episodes of apnea is more than 30 times, this kind of person is suffering from sleep apnea syndrome. Patients with sleep apnea syndrome can easily lead to sudden death from suffocation, and also easily induce cardiovascular diseases such as hypertension and coronary heart disease. Common snoring is one of the common symptoms of sleep apnea syndrome. [0004] The current clinical di...
