Technical Field

[0001] The invention relates to the technical field of oral muscle strength measurement, and in particular to an oral biomechanics capsule-type detector. Background Art

[0002] As we age, oral health is essential to maintaining life and ensuring its quality. Clinical evaluation of oral function usually includes analysis of mouth opening, speech, and chewing ability. Chewing and swallowing function play an important role in eating, safe transportation, and nutritional intake. In clinical studies, maximum voluntary bite force, maximum tongue pressure, maximum lip force, and tongue-lip movement function are used to analyze and evaluate oral function.

[0003] At present, there is a lack of research on comprehensive devices that can measure the three oral forces of bite force, tongue force and lip force. Such single or partial function devices cannot meet the needs of comprehensive evaluation of oral function. Due to the limitations of the human oral space, high requirements are placed on the structural design of the device. Considering that the hardness of the part of the measuring device that contacts the human oral cavity is one of the factors that affect the measurement of maximum bite force, maximum tongue force and maximum lip force. Therefore, it is particularly important to invent an oral biomechanical testing instrument with low cost, high measurement accuracy and high comfort. Summary of the invention

[0009] Furthermore, the main body is in a flat block shape, and the middle section of each chamber of each capsule-type detection structure coincides with the middle section of the main body.

[0010] Furthermore, the chambers arranged in the tooth stress-bearing area are spherical and distributed in a honeycomb shape.

[0011] Furthermore, the chambers arranged in the tongue and lip stress-bearing area are columnar and distributed parallel to each other.

[0012] Furthermore, in the sac-type detection structure, each of the chambers is connected to the adjacent chambers via branch pipes opened on the main body, and the sac-type detection structure also includes a main pipe opened on the main body and connected to the overall chamber formed by the plurality of chambers, and the pressure sensor is connected to the main pipe.

[0013] Furthermore, the tooth stress area and the tongue and lip stress area are located at the rear of the main body, and the main pipeline of each capsule-type detection structure extends to the front of the main body.

[0035] See also Figures 1 to 7 .

[0036] In an optional embodiment of the present invention, an oral biomechanics capsule detector includes:

[0037] The main body 1 is made of elastic material and has a tooth stress area for receiving tooth occlusion and a tongue-lip stress area 14 for receiving tongue pressure and / or lip pressure;

[0038] The capsule-type detection structure 2 includes a plurality of chambers 21 opened in the main body 1 and interconnected with each other, and a pressure sensor for measuring the overall chamber pressure formed by the plurality of chambers 21 (for the sake of concise description, not shown in the figure, the pressure sensor can use an existing device capable of measuring pipeline fluid pressure), and the tooth stress area and the tongue and lip stress area 14 are each provided with at least one capsule-type detection structure 2.

[0039] When the detector of the present invention needs to measure the tooth bite force, the tooth force-bearing area of ​​the main body 1 is extended between the upper and lower teeth of the person being tested, and the person being tested begins to bite hard, thereby squeezing the chamber 21 of the capsule-type detection structure 2 in the tooth force-bearing area, so that the pressure value of the overall chamber formed by each chamber 21 will change and be detected by the pressure sensor, and the pressure signal is analyzed, and then the force data of the tooth bite can be measured; when it is necessary to measure the tongue force of the tongue against the palate, the tongue and lip force-bearing area 14 of the main body 1 is placed on the front area of ​​the upper surface of the tongue of the person being tested, and the person being tested moves the tongue in the direction of the palate, so that force data can also be obtained through the capsule-type detection structure 2 in this area; similarly, when it is necessary to measure the lip pursing force, the tongue and lip force-bearing area 14 of the main body 1 is also extended between the upper lip and lower lip of the person being tested, and the person being tested performs a lip pursing action, and then the lip pursing force can be measured.

[0040] The present invention can measure the tooth bite force, lip pursing force and tongue force in the direction of the upper jaw, and has the characteristics of simple structure, safety and hygiene, high comfort, reliable measurement, easy operation, and reusable after cleaning. It is helpful for clinical evaluation and diagnosis, and provides an effective auxiliary means for oral rehabilitation and orthodontic treatment.

[0041] In the present invention, the elastic material used for the main body 1 may be, for example, silicone, nylon or polyurethane elastomer (TPU), and the present invention does not impose any special restrictions thereon; the main body 1 may be set to different sizes according to different human oral biological data, and the chambers 21 in different force zones may also be designed and arranged accordingly according to the human oral biological data.

[0042] In one embodiment, the tooth force area of ​​the main body 1 includes a left tooth force area 11, a right tooth force area 12 and a front tooth force area 13, and the tongue and lip force area 14 is located between the left tooth force area 11 and the right tooth force area 12. The left tooth force area 11, the right tooth force area 12, the front tooth force area 13 and the tongue and lip force area 14 are respectively provided with a capsule-type detection structure 2. With this design, the bite force of the teeth on both sides and the front teeth can be measured in different areas. When used:

[0043] The capsule-type detection structure 2 of the left tooth stress area 11 corresponds to the contact area from the first premolar to the second molar or the third molar on the left side of the human body;

[0044] The capsule-type detection structure 2 of the right tooth stress area 12 corresponds to the contact area from the first premolar to the second molar or the third molar on the right side of the human body;

[0045] The capsule-type detection structure 2 of the front teeth stress-bearing area 13 corresponds to the contact area between the left canine and the right canine of the human body.

[0046] The force-bearing area is divided according to the biological data of the human oral cavity, and information of the corresponding area is collected as much as possible, thereby improving the accuracy of the measurement data.

[0047] In one embodiment, the chamber 21 disposed in the force-bearing area of ​​the teeth is spherical and distributed in a honeycomb shape. This design, taking into account the magnitude of the human bite force and the elasticity of the main body material, enables the overall chamber formed by the multiple chambers to disperse the force more evenly when subjected to external force, avoiding the influence of the bite position, and also avoiding the teeth from damaging the chamber during measurement, thereby improving the stability of the overall chamber to a certain extent.

[0048] In one embodiment, the chambers 21 arranged in the tongue-lip force area 14 are columnar and parallel to each other. Considering the differences in the tongue force against the upper jaw and the lip-puckering force of the human body and the position of the force applied by the human body, the influence of the force position is avoided. This design can increase the contact surface of the overall chamber formed by multiple chambers and collect force information of the corresponding force area as much as possible.

[0049] In one embodiment, in the capsule-type detection structure 2, each of the chambers 21 is connected to the adjacent chambers 21 through branch pipes 22 provided on the main body 1. With this design, the fluid in the chamber 21 is easier to circulate and the pressure response is more sensitive. The capsule-type detection structure 2 also includes a main pipe 23 provided on the main body 1 and connected to the overall chamber formed by the multiple chambers 21, and the pressure sensor is connected to the main pipe 23. In a specific implementation, the inlet end of the main pipe 23 can be connected to one or more of the chambers 21 and / or one or more of the branch pipes 22, and can be connected to the overall chamber formed by the multiple chambers 21, so as to detect pressure.

[0050] In one embodiment, the tooth stress zone and the tongue and lip stress zone 14 are located at the rear of the main body 1, and the main pipe 23 of each capsule-type detection structure 2 extends to the front of the main body 1. With this design, the rear of the main body 1 is used to extend into the oral cavity, and the front of the main body 1 is used to hold or connect the following support body, which is more practical; and the main pipes 23 are extended to the front of the main body 1, which has little effect on the change of the measured stress zone, does not affect the force collection of the corresponding stress zone, and the value is more accurate and reliable. The pressure sensor can be installed at the outlet end of the main pipe 23.

[0051] In one embodiment, the main body 1 is in the shape of a flat block, and the middle section of each chamber 21 of each capsule-type detection structure 2 coincides with the middle section of the main body 1. The middle section here refers to the middle section in the thickness direction of the main body 1. The user bites along the thickness direction of the main body. This design ensures that the thickness from the surface of the main body 1 to the chamber 21 where the corresponding teeth of the upper and lower jaws of the human body contact is the same, avoiding inaccurate force information collection caused by different stiffness of the corresponding areas of the upper and lower teeth contacting the main body 1 due to thickness factors. More preferably, the middle section of each branch pipe 22 and each main pipe 23 also coincides with the middle section of the main body 1.

[0052] In a specific implementation, the main body 1 can be formed into two halves in a mid-section during manufacturing, and then bonded into a whole, so as to facilitate the formation of chambers and channels on the main body.

[0053] In one embodiment, hard plates 16 are respectively embedded on the upper and lower sides of each of the capsule-type detection structures 2 located in the tooth force-bearing area in the main body 1. The hard plates 16 are made of hard materials, such as plastic, iron sheets, etc. The hard plates 16 can evenly distribute the bite force of the tooth force-bearing area to each chamber 21 of the corresponding capsule-type detection structure 2, avoid the damage of the chamber 21 caused by pressure concentration, avoid the influence of the tooth bite position, and thus improve the stability of the overall chamber formed by multiple chambers.

[0054] In one embodiment, the upper and lower sides of the main body 1 are designed with wave-shaped curved surfaces corresponding to the tongue and lip force-bearing area 14. This design increases the contact area between the upper surface of the human tongue and lips and the cavity, more accurately captures the force applied to the overall cavity formed by multiple cavities, and also facilitates the placement of the upper surface of the human tongue and lips on the main body during measurement.

[0055] In one embodiment, gas, liquid or gas-liquid mixture can be filled into the chamber 21 of the bladder-type detection structure 2 through an external air pump, and the filling pressure of the bladder-type detection structure 2 in different stress-bearing areas can be the same or different, thereby changing the bearing capacity of the bladder-type detection structure 2 in different stress-bearing areas, so that the bearing capacity of different stress-bearing areas is the same or different, so that the detector can measure a larger pressure. In addition, it should be avoided that the pressure is too high during the measurement process to exceed the range of the signal acquisition module, resulting in inaccurate measurement.

[0056] In one embodiment, the detector of the present invention further includes a support body 3, and the main body 1 is detachably mounted on the support body 3. This design facilitates the disassembly and assembly of the main body 1 for cleaning or replacement. In a specific implementation, the support body 3 can be a pistol handle structure or a long handle structure, and the present invention does not impose any special restrictions, as long as it is convenient to hold.

[0057] In one embodiment, a slot 31 is provided on the support body 3, and the main body 1 can be detachably inserted into the slot 31. A card slot 15 is provided on the left and right sides of the main body 1, and buttons 32 are hinged on the left and right sides of the support body 3. A spring 33 is connected between one end of the button 32 and the support body 3, and the other end of the button 32 can be inserted into the corresponding card slot 15 under the elastic force of the spring 33 (a clearance hole for the button 32 to pass through is provided at the position of the corresponding card slot 15 on the support body 3). With this design, after the main body 1 is plugged in, the button can position the main body 1 to improve stability. When disassembly is required, only one end of the button needs to be pressed to pull the other end of the button out of the card slot 15 to release the main body 1, and then the main body 1 can be removed.

[0058] In one embodiment, in order to realize the function of inflating the sac-type detection structure 2 to change the bearing capacity of the stress-bearing area, the support body 3 can be set as an external or internal air pump structure, and the external air pump handle structure uses an air pipe to connect the air pump and the main channel pipe of each stress-bearing area on the main body 1.

[0059] For specific implementation, see Figure 8 , a signal processing module can also be set, which includes a signal conditioning unit, an analog-to-digital conversion unit and a communication unit. When the capsule-type detection structure 2 is deformed by force, the chamber 21 inside it is deformed by force, and the pressure is collected by the pressure sensor and converted into an electrical signal. The corresponding relationship between the known pressure change and the output electrical signal change is obtained by calibration, and the data size of the corresponding force area can be obtained by measuring the electrical signal; the signal conditioning unit is used to obtain the force signal collected by the pressure sensor and convert the force signal into a conditioning signal, the analog-to-digital conversion unit is used to obtain the conditioning signal and convert it into a digital signal, and the communication unit is used to obtain the digital signal and send the digital signal through wired or wireless communication. The specific method of wireless communication includes but is not limited to Bluetooth transmission, WiFi transmission or infrared transmission, such as sending to a computer, and there is a related program for processing digital signals in the computer, and the data can be processed through the related program, and the valuable analysis results can be fed back to the user. The signal processing module can be encapsulated inside the support body 3.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
