[0031] Figure 1 A schematic diagram of the overall structure of an existing dental appliance is shown. As shown in the figure, the dental appliance 100 includes a U-shaped pad 102, the outer edges of the U-shaped pad 102 extend upward and downward respectively to form a lip stop 101, the inner edges of the U-shaped pad 102 extend upward and downward respectively to form a tongue stop 103, and a plurality of air outlet holes 104 are provided in the middle of the lip stop 101. The U-shaped pad 102, the lip stop 101 and the tongue stop 103 together form a dental appliance 100 adapted to tooth occlusion.

[0032] The present application provides a wearing indication device for the above-mentioned dental appliance 100, which can determine whether the dental appliance 100 is worn in the mouth by analyzing changes in certain signals from the nasal cavity. Figure 2-Figure 4The overall structural schematic diagram, top view and cross-sectional view of the wearing indication device of some embodiments of the present application are respectively shown. As shown in the figure, the wearing indication device of the present application includes a housing and a sensor module 3, a control module and a power module disposed in the housing;

[0033] The sensor module 3 is used to collect signals from the nasal cavity; specifically, the signal can be at least an acoustic signal generated by the exhaled gas from the nasal cavity, a pressure signal generated by the exhaled gas from the nasal cavity, or a carbon dioxide concentration signal. Further, the sensor module 3 shown includes at least one of an acoustic sensor, a carbon dioxide concentration sensor, and a gas pressure sensor.

[0034] The control module is used to process and analyze the signals collected by the sensor module 3 to determine whether the dental appliance 100 is worn in the mouth, and the control module can also store the above data so as to facilitate the subsequent retrieval and use of the above data as needed; it can be imagined that the control module can adopt any electronic device, system or equipment such as a microprocessor that can achieve the above-mentioned processing, analysis and storage of data;

[0035] The power supply module is electrically connected to the sensor module 3 and the control module respectively to supply power to them.

[0036] Specifically, the shell includes a limiting portion 11, a receiving portion 12 and a boss 13. The limiting portion 11 is used to be detachably connected to the dental appliance 100, and the receiving portion 12 is located on the side of the limiting portion 11 away from the dental appliance 100; when the limiting portion 11 is connected to the appliance 100, the receiving portion 12 is located outside the mouth, and the boss 13 is located on the upper end surface of the receiving portion 12 facing the nasal cavity.

[0037] Specifically, the limiting portion 11 includes two protrusions, which cooperate with the air outlet hole 104 on the dental appliance 100; optionally, the connecting portion may also include more than two protrusions to further stabilize the connection; preferably, the protrusion is cylindrical, and the diameter of each cylindrical protrusion is not less than the diameter of the air outlet hole 104 of the appliance 100 that cooperates with it, so that the protrusion and the air outlet hole 104 form an interference fit.

[0038] In some preferred embodiments, the side of the accommodating portion 12 close to the limiting portion 11 further includes a guide plate portion 121, both ends of which are configured to be curved and the degree of curvature matches the lip stopper 101 of the orthodontic device 100 to improve wearing comfort.

[0039] Furthermore, a signal strengthening structure 2 connected to the atmosphere is provided in the boss 13. When the wearing indication device is connected to the dental appliance 100 for use, the port of the signal strengthening structure 2 connected to the atmosphere faces the nasal cavity, so as to transmit and amplify the signal from the nasal cavity.

[0040] Figure 4-Figure 6 The signal enhancement structure 2 in different specific embodiments is shown respectively. Specifically, the signal enhancement structure 2 can be a cavity structure 21, a flow channel structure 22 or a combination of the two, as long as a connected gas passage is formed; further, the sensor module 3 is located in the signal enhancement structure 2, and the signal from the nasal cavity is amplified after passing through the signal enhancement structure 2, which is more conducive to the sensor module 3 to collect the signal and the subsequent processing and analysis, thereby improving the accuracy of the judgment.

[0041] In some preferred embodiments, the inner side surface of the signal enhancement structure 2 is an arc-shaped surface to enhance the gas vibration caused by the collision between the gas and the inner surface of the cavity and thus amplify the signal.

[0042] In some preferred embodiments, a plurality of raised textures are provided on the inner side surface of the signal enhancement structure 2 to further enhance the gas vibration and thus amplify the signal.

[0043] In some specific embodiments, the horizontal distance d between the port center of the signal enhancement structure 2 and the end face on the shell 1 that contacts the dental appliance 100 is 0.5 to 7 cm, and the vertical distance h between the bottom of the signal enhancement structure 2 and the end face of the boss 13 facing the nasal cavity is 0.5 to 5 cm. When in this position, the distance between the sensor module 3 and the nasal cavity can meet the collection of the changing signal.

[0044] The use principle of the present application is as follows: when in use, the limiting portion 11 of the wearing indication device of the present application is connected to the air outlet 104 on the dental appliance 100. When the dental appliance 100 is worn in the mouth, the accommodating portion 12 of the wearing indication device is located outside the mouth, and the boss 13 on the end surface of the accommodating portion 12 faces the nasal cavity. The port of the signal enhancement structure 2 arranged in the boss 13 is located under the nasal cavity and can receive gas exhaled from the nasal cavity. The gas exhaled from the nasal cavity enters the signal enhancement structure 2 and collides with its inner side surface, causing gas vibration and generating an acoustic signal, which is collected by the acoustic sensor placed in the signal enhancement structure 2 and transmitted to the processing module for processing and analysis; when the dental appliance 100 is removed from the mouth, the amount of gas exhaled from the nasal cavity entering the signal enhancement structure 2 will be significantly reduced, so the acoustic signal generated by the collision and vibration with the inner side surface will also change significantly, which can be specifically manifested as a significant change in the sound frequency or sound pressure value. Therefore, the wearing condition of the dental appliance 100 can be judged by analyzing the change in the signal. Similarly, the sensor module 3 can also be a carbon dioxide concentration sensor or a gas pressure sensor. Since the position change of the dental appliance 100 causes the amount of nasal exhaled gas entering the signal enhancement structure 2 to change, the collected carbon dioxide concentration or gas pressure signal changes accordingly. Therefore, the wearing condition of the dental appliance 100 can be judged by analyzing the signal changes.

[0045] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications may be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
