Description

Sleep apnea syndrome auxiliary treatment pillow based on snoring recognition

technical field

The invention relates to an auxiliary treatment pillow, in particular to an auxiliary treatment pillow for sleep apnea syndrome based on snoring recognition.

Background technique

Snoring symptoms are mainly due to narrowing or obstruction of the upper airway. According to the current research results, about 20% to 40% of the population is troubled by different degrees of snoring symptoms. Studies have shown that persistent snoring symptoms have great harm to the patient's body and life. Snoring is also one of the most common clinical symptoms of sleep apnea syndrome (Sleep Apnea Syndrome, SAS). According to relevant survey results, more than 3,000 people die at night related to sleep apnea every day in the world. Therefore, snoring must not be taken lightly, and its seriousness must be fully realized, diagnosed and treated as soon as possible.

At present, there are three main means of relieving snoring symptoms at home and abroad: interventional medical devices to relieve snoring, non-invasive medical devices to relieve snoring, and surgery or drugs. Among them, the means of alleviating snoring through non-invasive medical devices brings relatively little pain to patients and has a slight impact on sleep quality. In addition, among many simple SAS diagnosis methods, the detection and screening of SAS by directly analyzing the patient's snoring signal is the most common and extensive method.

Therefore, urgently need to solve the above-mentioned problem.

Detailed ways

The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , the present invention discloses a pillow for auxiliary treatment of sleep apnea syndrome based on snore recognition, which includes a voice device terminal system 1 and a server terminal system 2 . The voice equipment terminal system includes voice data acquisition module 3, processor module 4, inflation and deflation module 5, air pressure monitoring module 6, data transmission module 7 and inflatable pillow 8, and the equipment terminal system 1 communicates with the air through the wireless transmission of data transmission module 7. The server-side systems 2 interact with each other, and the server-side 2 stores and displays the snoring interval information.

The voice data collection module 3 of the present invention is used to seamlessly collect the voice data in the sleeping environment of the user and transmit it to the processor module 4 . In the software part of the voice data acquisition module, in order to achieve the purpose of real-time and complete detection of effective voice segments, it is necessary to achieve seamless data acquisition, so direct memory access (Direct Memory Access, DMA) and double buffering (also called ping-pong cache) method. The entire voice acquisition software setting process is as follows: the voice data first enters the LM385 through the microphone, and finally outputs an analog signal. Then, the analog signal triggers the ADC1 to sample through the timer TIM2, and converts it into a digital signal. At the same time, the DMA controller transfers the collected digital signals to the DMA BUFFER through DMA. When the DMA BUFFER is full, trigger the DMA interrupt and enter the DMA interrupt service routine. In the DMA interrupt service routine, complete the exchange task of the ping-pong cache. Next, the CPU will perform real-time endpoint detection on the contents of the DMA BUFFER and judge whether the frame of voice data is valid voice data.

The processor module 4 of the present invention is used for real-time analysis and processing of the voice data provided by the voice data acquisition module, through the dual-threshold method based on short-term energy and short-time zero-crossing rate as an endpoint identification method, Mel frequency cepstral coefficient as a feature parameter, The K nearest neighbor algorithm is used as a snoring recognition algorithm to finally identify the snoring part, and store the snoring interval information as data; it is used to comprehensively analyze the snoring data and the air pressure value data of the inflatable pillow provided by the air pressure monitoring module, and control the inflation and deflation module. The inflatable pillow is inflated or deflated, thereby adjusting the height of the pillow to alleviate the user's snoring symptoms; it is also used to transmit the snoring interval information to the server-side system through the data transmission module.

The inflation and deflation module 5 and air pressure monitoring module 6 of the present invention are used for inflation and deflation of the inflatable pillow 8 . The inflation and deflation operations of the airbags in the pillow can adjust the height of the pillow, thereby correcting the user's head posture to reduce snoring symptoms. The inflation and deflation module 5 controls the working state of a two-position three-way miniature solenoid valve and a miniature air pump through the driver IC and the processor module 4, thereby inflating and deflation of the inflatable pillow 8. The air pressure monitoring module 6 is used to measure the gas pressure of the inflatable pillow, and returns a standard voltage signal to the processor module, so as to prevent the air pressure from being too large due to over-inflation, which will eventually cause the pillow to explode and cause harm to the user.

The data transmission module 7 of the present invention is used for communication between the equipment terminal system 1 and the server terminal 2 . The present invention adopts the principle of WiFi transmission, uses the JSON data format as the transmission format, and enables the equipment terminal system 1 to perform data communication with the server terminal 2 through the ESP8266 module. The device terminal system 1 packages and transmits the snoring interval data to the server system 2, and the server system 2 sends a response to the data packet sent before the device terminal system 1.

The server-side system 2 of the present invention provides a way to store and query the database for the snoring interval information sent by the equipment terminal system 1, and at the same time, the server needs to perform data processing on the snoring interval information, and give a clue as to whether the user suffers from sleep apnea syndrome. Make suggestions. In addition, for the data security and considerate service of the entire system, the system server also provides additional functional modules such as user registration and login, user management, and notification reminders. The entire server side adopts B/S software architecture, which correspondingly bears a relatively large task pressure.

The foregoing embodiments are only preferred implementations of the present invention. It should be pointed out that those skilled in the art can make several improvements and equivalent replacements without departing from the principle of the present invention. Technical solutions requiring improvement and equivalent replacement all fall within the protection scope of the present invention.
