[0025] Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] In the description of the present application, it should be noted that the terms "first", "second" and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] The bite force testing device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, in a first aspect of an embodiment of the present application, a bite force testing device is provided, which may include:

[0030] An ergonomic gutta-percha, wherein a gasket is arranged on the outer surface thereof corresponding to the tooth occlusal position, the gasket is detachably connected to the ergonomic gutta-percha, and a pressure sensor is arranged between the ergonomic gutta-percha and the gasket;

[0031] A signal collector is communicatively connected to the pressure sensor, and is used to convert the electrical signal collected by the pressure sensor into a bite force value.

[0032] The device of this embodiment uses a pressure sensor and a signal collector to accurately test the child's bite force level, and can intuitively display the child's bite force, which is convenient for quantitative measurement of the child's bite force, facilitating doctors to accurately judge the child's bite force, and providing a scientific basis for subsequent treatment and family dietary recommendations. In addition, a detachable gasket is provided on the ergonomic teether. Even if the gasket is damaged, the ergonomic teether will not be damaged. It only needs to replace the gasket to be reused, which greatly reduces the cost of use.

[0033] In some embodiments, the ergonomic teether is provided with a groove matching the shape of the gasket corresponding to the tooth occlusal position;

[0034] The gasket is embedded in the groove.

[0035] A sliding groove can be set on the inner wall of the groove of this embodiment, and a sliding rail matching the sliding groove is set on the gasket. The gasket is assembled in the groove by clamping the sliding rail and the sliding groove. It should be noted that the groove width of the sliding groove needs to be slightly larger than the sliding rail. In this way, after the sliding rail and the sliding groove are clamped, the gasket has a certain upward and downward movable space, so that the bite force can be accurately measured.

[0036] Specifically, Figure 2 As shown, the ergonomic teether can include an upper shell and a lower shell. The upper shell is provided with a positioning protrusion, and the lower shell is provided with a positioning groove. The positioning groove limits the positioning protrusion to slide only up and down (i.e., the extension direction of the positioning protrusion). In other words, the upper shell can only move up and down relative to the lower shell, and cannot move forward, backward, left or right. In this way, the bite force data tested is more accurate. In addition, the upper shell is also provided with an upper positioning hole, and the lower shell is also provided with a lower positioning hole. Bolts are passed through the upper positioning hole and the lower positioning hole to fix the upper shell and the lower shell together. More specifically, the upper shell is as shown in FIG. Figure 3 As shown, the lower shell is Figure 4 As shown, the lower shell is also provided with a receiving groove for placing the pressure sensor and a wiring groove. The pressure sensor in this embodiment can be a thin film sensor.

[0037] In some embodiments, the thickness of the gasket is greater than the depth of the groove.

[0038] The gasket in this embodiment is higher than a portion of the ergonomic teether, which is convenient for positioning teeth and testing the bite force.

[0039] In some embodiments, the gasket is made of thermoplastic polyurethane elastomer.

[0040] In this embodiment, the gasket material is thermoplastic polyurethane elastomer (TPU), which has a much lower hardness than metal and has better toughness. It feels comfortable to bite, does not cause pain, and is not easy to be damaged.

[0041] In some embodiments, the gasket is snap-fitted to the inner wall of the groove.

[0042] A card slot can be provided on the inner wall of the groove of this embodiment, and a card protrusion matching the card slot is provided on the gasket. The gasket can be assembled in the groove by snapping the card protrusion and the card slot. It should be noted that the notch of the card slot needs to be slightly larger than the card protrusion, so that a certain amount of movable space is left after the card protrusion and the card slot are snapped together, so that the bite force can be accurately measured.

[0043] In some embodiments, a plurality of anti-slip protrusions are disposed on the surface of the gasket.

[0044] The protrusions on the gasket of this embodiment are to prevent slipping during engagement, which would cause inaccurate testing.

[0045] In some embodiments, the ergonomic teether is made of nylon fiber reinforced material.

[0046] The ergonomic teether of this embodiment can use 7200 nylon fiber-reinforced material to ensure the main body strength and non-deformation.

[0047] Exemplarily, the pressure sensor is a resistive sensor. During the test, when the pressure sensor is pressurized, the resistance changes, which is basically linear within the range, and the following can be obtained:

[0048] F=KRs (1)

[0049] Among them, F is the bite force value, K is a constant, and Rs is the resistance of the pressure sensor.

[0050] In some embodiments, the ergonomic teether is in a T-shaped structure, and the head of the ergonomic teether is slightly concave. The ergonomic teether is made of transparent food-grade silicone material, which is convenient for observing bite marks, and normal bites are harmless to the body even if there is wear.

[0051] For example, food-grade silicone materials of different hardness can be selected according to the age and ability of the children. Teething gums can be divided into three grades: low, medium and high. Low-hardness materials are suitable for young children with poor chewing function and whose diet is mainly liquid or semi-liquid. Medium-hardness materials are suitable for children whose diet is mainly fine and normal food. High-hardness materials are suitable for older children with relatively good functions and who mainly eat normal food, so that the subjects can have a better experience during the test.

[0052] The raw materials of the silica gel material may include: 65-80% of liquid silica gel matrix, 18-33% of pigment, and the remainder of dispersant.

[0053] Wherein, the dispersant is methyl silicone oil; the viscosity of the methyl silicone oil is 850-1150 cst; the pigment can be one or more combinations of pigment red, pigment orange, pigment yellow, pigment green, pigment blue, and pigment violet.

[0054] For example, the model of pigment red is DPP Red SR2P, the model of pigment orange is Cromophtal Orange k2960, the model of pigment yellow is Yellow YG, the model of pigment green is Irgalite Green GFNP, the model of pigment blue is Heliogen Blue K 7096, and the model of pigment violet is Cinquasia Pink k 4430FP.

[0055] Exemplarily, the model of the liquid silicone matrix is ​​BT-1300.

[0056] The above-mentioned food-grade silicone material uses liquid silicone matrix as a carrier and pigment as a raw material of color powder. The prepared silicone liquid color paste has excellent UV resistance and weather resistance, does not contain metal ions and organic ammonia compounds or other compounds that affect the Pt-H vulcanization system of liquid silicone, does not affect the vulcanization speed of silicone, complies with FDA and LFGB standards, and can be directly applied to the processing of liquid silicone materials such as silicone bottles, nipples, bibs, etc. of baby series that meet FDA standards;

[0057] In addition, a variety of colors can be selected as the basic colors for color matching. These pigments can be used to mix colored glues of different colors, and can also be colored individually according to actual needs. In addition, it has the characteristics of heat resistance, light resistance, migration resistance, color separation resistance, frost resistance, acid and alkali resistance, strong tinting strength, high solid content, and good compatibility. The pigment and dispersant have good solubility in the liquid silicone matrix, which is of great benefit to reducing the circulation cost of production materials, and has stable performance and a very long shelf life.

[0058] In addition, the gasket can be designed according to the size of the mouth. For older patients, the gasket can be added to make the mouth opening and closing degree of the subject in the bite force test in a suitable position, so that the patient's maximum bite force can be measured more accurately. The gasket can be a silicone sleeve that matches the mouth shape, and the silicone sleeve is placed on the teether.

[0059] For ease of use, this embodiment adopts a T-shaped structure, which is split in the middle and can be embedded with a sensor. The head of the gutta-percha is slightly concave to facilitate tooth occlusion.

[0060] An anti-skid portion is also provided between the gasket and the pressure sensor, and the anti-skid portion can prevent the pressure sensor from falling off from the inside of the gutta-percha.

[0061] The pressure sensor comprises a plug interface, a shell, a chip, a pressure sensor, a diaphragm and a stainless steel base. The pressure sensor and the stainless steel diaphragm are installed on the stainless steel base in sequence from top to bottom.

[0062] The plug interface is installed on the shell; the chip is accommodated in the shell and is located below the plug interface.

[0063] The pressure sensor is accommodated in the shell and is located below the chip; the stainless steel component is accommodated in the shell and is located below the pressure sensor.

[0064] The shell includes a first connecting part and a second connecting part, the second connecting part is a joint base, and a first boss for placing the chip is formed on the inner side of the first connecting part; an inner flange is provided at the top end of the first connecting part, and an outer flange is provided at the bottom end of the plug interface, and the outer flange is clamped between the inner flange and the chip.

[0065] The stainless steel base is integrally arranged with the stainless steel diaphragm, and the stainless steel base is stably arranged inside the gutta-percha.

[0066] An O-ring is arranged on the outer wall of the stainless steel base, and silicone oil is added between the stainless steel diaphragm and the pressure sensor.

[0067] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
