Description

Technical Field

[0001] The invention belongs to the field of snoring prevention devices, in particular to a snoring prevention device capable of automatically adjusting to resist muscle fatigue. Background Art

[0002] Snoring devices are equipment used to reduce or eliminate snoring symptoms. Their development history started from early simple physical devices such as braces-type snoring devices. Oral snoring devices physically adjust the position of the mandible or tongue to expand the pharynx, but the effect may be affected by obvious foreign body sensation, discomfort when wearing, or even falling off. Nasal snoring devices improve nasal congestion and keep the nasal cavity open, but some products such as snoring nose clips may cause discomfort and have limited effects. Liquid snoring devices lubricate and soften the nasopharyngeal mucosa to reduce upper airway resistance, but their ingredients may contain hormones or vasoconstrictor drugs and are not suitable for long-term use. Smart snoring pillows monitor snoring through sensors and adjust the position of the head to change the shape of the airway, but intervention actions are not suitable. Ventilator snoring devices use continuous positive pressure airflow to open the collapsed airway, but there are defects such as inconvenience in carrying and possible dependence. Summary of the invention

[0003] The present invention provides an anti-snoring device capable of automatically adjusting to resist muscle fatigue, comprising a split brace, a sensing module, an integrated chip and a release module. The split brace comprises left and right braces respectively sleeved on left and right posterior molars and an elastic pressure strip connecting the braces. The split brace shell is formed by polyurethane 3D printing, and a resin-molded tooth socket is embedded inside. A battery, an integrated chip and an internal signal transmission line are arranged between the tooth socket and the shell. The sensing module is arranged on the inner working surfaces on both sides of the split brace.

[0004] Preferably, the sensing module is attached to the inner wall of the braces, with the upper part in the shape of a longitudinal strip, extending downward to the bottom and having an arc-shaped surface gradually convex toward the root of the tongue, and the bottom cross-section of the sensing module is in the shape of a triangle with an arc. The sensing module includes an elastic strip connecting the braces on both sides at the top, a flexible pressure sensor at the bottom, and humidity monitors arranged on both sides of the bottom.

The analog signal provided by the sensing module is transmitted to the analog-to-digital converter on the integrated chip, and the digital signal is transmitted to the signal processor after the signal mode is converted by the analog-to-digital converter. The signal processor then transmits the electrical signal to the signal transmitter.

[0007] Preferably, the release module includes a signal receiving device and an electrode. After receiving the signal from the signal transmitter, the release module controls the electrode to generate a weak current.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0012] As Figures 1 to 8 shown, the present invention includes a split dental appliance 1, a sensing module 2, an integrated chip 3, and a release module 4. The split dental appliance 1 includes dental appliances respectively sleeved on the lower molars on the left and right sides and an elastic pressing strip 21 connecting the dental appliances. Each dental appliance has three working surfaces, and the three working surfaces are integrally arranged in an arc shape and are formed by polyurethane 3D printing. The occlusal part at the upper part of the dental appliance has a certain width, and an alveolar socket nested with a resin mold is arranged inside. The top and the inner and outer sides together form a buckling space that can be buckled on the teeth. The pressing groove of the resin mold is a customized flexible interlayer, which can be wrapped around the lower molars on both sides of the oral cavity according to the oral environment of different users. A battery 5 is arranged between the alveolar socket and the working surface. An integrated chip 3 and internal circuits are arranged on one side of the battery 5. Sensing modules 2 are oppositely arranged on the opposite working surfaces of the dental appliances on both sides of the split dental appliance 1. Circuits and signal transmission lines are arranged inside the elastic pressing strip 21.

[0013] As Figure 3 shown, the upper part of the sensing module 2 is in a strip shape, the bottom extends downward and is provided with an arc gradually protruding towards the root of the tongue. The cross-section of the bottom of the sensing module 2 is in a triangular shape with an arc. After being worn properly, the front end extends into the bottom of the root of the tongue, and the arc-shaped fitting surface will not cause discomfort to the wearer after being worn properly. The upper part of the sensing module 2 is connected to the elastic pressing strip 21. A flexible pressure sensor 22 is arranged on the arc surface at the bottom of the sensing module 2, and humidity monitors 23 are arranged on both sides of the arc surface. A disconnection monitoring device is arranged at the connection between the elastic pressing strip 21 and the upper end of the sensing module 2. When in use, it covers the upper part of the root of the tongue. Circuits and lines connected to the sensing module 2 are arranged inside the elastic pressing strip 21 for power supply and signal transmission. When the elastic pressing strip 21 is arched by the root of the tongue during use, the disconnection monitoring devices on both sides of the elastic pressing strip 21 will be triggered, and the analog signal will be transmitted to the analog-to-digital converter 31 on the integrated chip 3 in real time. Two groups of flexible pressure sensors 22 are also oppositely arranged at the place where the bottom of the sensing module 2 fits the side wall of the tongue. When the tongue collapses backward, the pressure on the flexible pressure sensor 22 will show a different pressure from the normal sleep state. At this time, the flexible pressure sensor 22 will also transmit the trigger signal to the analog-to-digital converter 31. A humidity monitor 23 is also arranged at the end of the sensing module 2 that extends into the root of the tongue. When the airway becomes narrow during the user's sleep, resulting in an increase in saliva in the oral cavity, the humidity monitor 23 collects the humidity analog signal and transmits it to the analog-to-digital converter 31.

[0014] AsFigure 1 As shown, the integrated chip 4 is disposed inside the working surfaces on the two outer sides of the split dental appliance 1. The integrated chip 3 includes an analog-to-digital converter 31, a signal processor 32, and a signal transmitter 33 that are arranged in parallel. A button battery 5 is provided on the side of the integrated chip 3 to provide energy for the entire system.

[0015] The entire device is wrapped with poly-o-phenylenediamine film 11. An acetate cellulose film 221 is used to coat the upper part of the flexible pressure sensor 22 to combat bacteria in the oral cavity. A carbon nanofiber pad 231 is provided on the surface of the monitoring port of the humidity monitor 23 to resist moisture.

[0016] As Figure 7 、 Figure 8As shown in the figure, during use, when the user wears it properly, the device automatically powers on and works. The split dental appliance 1 is set on the lower molars on both sides, the elastic pressing strip 21 covers the upper part of the tongue root, and the flexible pressure sensor 22 and the humidity monitor 23 penetrate into the bottom of the tongue root. At this time, the user has not entered the sleep state, and all signals of the snore stopper are normal. When the user enters the sleep state, the tongue root gradually collapses backward, and both sides of the elastic pressing strip 21 are pulled up. The disconnection monitoring device, as the front-end sensing element, quickly captures the disconnection event and transmits the corresponding analog signal to the analog-to-digital converter 31 in real time. The analog-to-digital converter 31, as the core module for analog-digital signal conversion, quickly converts the received analog signal into a digital signal and then transmits the digital signal to the signal processor 32 through the internal data bus. However, at this time, it may only be the change in the position of the tongue. When the tongue position gradually moves downward, the flexible pressure sensor 22 monitors a pressure signal different from the normal state. The flexible pressure sensor 22, as a high-precision pressure sensing component, can keenly monitor the pressure signal different from the normal state. At this time, the flexible pressure sensor 22 continuously inputs the analog signal of the pressure change into the analog-to-digital converter 31. The analog-to-digital converter 31 converts the analog signal into a binary digital signal with an extremely high sampling frequency and conversion accuracy and transmits it to the signal processor 32 through the data interface. Finally, as the sleep duration increases, the airway of the user remains narrow, causing the humidity in the oral cavity to increase. At this time, the humidity monitor 23, as the environmental parameter sensing module, timely detects the abnormal humidity and transmits the humidity analog signal to the analog-to-digital converter 31. The analog-to-digital converter 31 once again performs its signal conversion function, converts the humidity analog signal into a digital signal and transmits it to the signal processor 32. The signal processor 32 makes judgments and processes the above three signals in real time. Through the pre-written algorithm, it performs threshold comparison and logical judgment on these three digital signals. If all three digital signals reach the preset threshold, the signal processor 32 can determine that the user is in a snoring state. The signal processor 32 generates the corresponding control electrical signal and transmits it to the signal transmitter 33. The signal transmitter 33, as the signal transmission module, transmits the control signal to the release module 4. The release module 4 controls the electrode 41 to generate a weak current according to the received signal. The electrode 41, as the actuator, stimulates the tongue root muscles through the weak current to make them produce regular peristalsis, thereby effectively reducing the snoring frequency and realizing the intelligent monitoring and intervention of the human physiological state by the embedded system.
