Household sleep apnea monitoring system and method thereof

Abstract

An embodiment of the invention discloses a household sleep apnea monitoring system and a method thereof. The method includes: acquiring breath sound signals during sleeping of a subject; packing signal data and wirelessly transmitting; drawing expiratory and inspiratory phase diagrams, marking starting and ending points of expiratory and inspiratory phase in each time, and judging whether sleep apnea happens or not; converting the expiratory and inspiratory phase diagrams with sleep apnea into corresponding average power spectrums, and determining sleep apnea characteristics; judging a sleep breathing state, and feeding back sleep apnea monitoring information. In implementation of the embodiment, due to adoption of the method for judging the sleep breathing state through analysis of lung breath sounds, inaccuracy in snore detection and uncleanness and uncomfortableness caused by a mask adopted for direct acquisition of the breath sounds are avoided; influences in monitoring under a sleeping state of a user are reduced, and the user can quickly and accurately know own daily sleep state and is provided with some initial references.

Description

technical field [0001] The invention relates to the technical fields of mobile medical care and intelligent diagnosis, in particular to a home sleep apnea monitoring system and a method thereof. Background technique [0002] Sleep apnea syndrome is divided into three types: obstructive sleep apnea, central sleep apnea and mixed sleep apnea. Of these, the most common is obstructive sleep apnea. Since the pathogenesis of obstructive sleep apnea syndrome and central sleep apnea syndrome are different, and the treatment methods are also very different, it is of great clinical value to correctly distinguish between the two. There are currently four monitoring and analysis methods available, including: [0003] (1) Use a mask to collect breath sounds. This method is to use a restrictive headband to fix the mask to the face of the test subject, use the transducer and microphone installed in the mask to capture the signal of sound or air flow, and identify the apnea or hypopnea e...

Problems solved by technology

Because the catheter must be inserted through the nostril during measurement, it will not only cause discomfort to the patient, but also affect the quality of sleep of the patient, so it is not suitable for popularization.

Moreover, this kind of detection system sometimes has air leakage, so it may need to be calibrated repeatedly during the measurement process, and it is not suitable for the home environment.
