Embodiment Construction

[0048] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0049] Such as Figure 6 The workflow is shown. First, the patient opens the smart phone APP program to take the front face image and the side face images on both sides, and then sends the front face image and the side face images to the image detection and signal processing device through Bluetooth. The signal processing device stores the received image and uses it to recognize the patient's face and judge whether it is in a supine or side lying state.

[0050] Since snoring is a characteristic performance of OSAHS, when the smart phone recognizes the sound of snoring, it sends command data to the image detection and signal processing device. After receiving the command, it turns on the LED intelligent supplementary light module and starts the face recognition and tracking program. Based on optimization The face detection and recognition algorithm of the o...

Abstract

The invention provides a monitoring device controlled based on an intelligent mobile phone for preventing obstructive sleep sudden death. The monitoring device includes the intelligent mobile phone, an image detection and signal treatment device and an oximeter. The image detection and signal treatment device includes: an image recognition and signal treatment module based on Digital Signal Processor (DSP), an RGB camera shooting module, a storage module and a wireless module. The recognition and signal treatment module includes: a heart rate signal analysis module, a snore signal analysis module and a breathe frequency analysis module. The heart rate analysis module is respectively connected to the RGB camera shooting module and the storage module and measures the sleep heart rate, the breathe, and the snore in non-contact manner, measures the blood oxygen saturation through the oximeter, fits a function according to negative correlation of the blood oxygen saturation and sleep apnea time, thereby improving the veracity and effectiveness of the oximeter, systematically analyzing the signal variation to recognize the sleep condition and to prevent the sleep sudden death.

Description

technical field [0001] The invention relates to a method for preventing sudden obstructive sleep death controlled by a smart phone and a monitoring device based on the method, belonging to the field of medical care equipment. Background technique [0002] Obstructive sleep apnea syndrome (OSAHS) is a disease that has not been widely recognized. It refers to repeated episodes of apnea and hypopnea occurring more than 30 times during nighttime sleep, or sleep apnea hypopnea. Index (AHI) greater than or equal to 5 times / hour, AHI is the number of apnea plus hypopnea per hour of sleep. Apnea refers to the complete cessation of respiratory airflow through the mouth and nose for more than 10 seconds during sleep; hypopnea refers to the reduction of respiratory airflow intensity (amplitude) by more than 50% compared with the baseline level during sleep, accompanied by a drop in blood oxygen saturation greater than the baseline level. Equal to 4%. According to the size of the apne...
