During each measurement, the contact end of the tongue top assembly only contacts the muscles of the area to be measured, and the force will not be dispersed, thereby improving the measurement accuracy. The connection sections in the tongue tip tongue top assembly 31, the tongue middle tongue top assembly 32, the left tongue top assembly 33, and the right tongue top assembly 34 are the same.

The tongue top contact end 331 on the left side of the tongue is the tongue top contact end, and the tongue top telescopic section 332 on the left side of the tongue is the telescopic section. The two ends of the tongue top telescopic section 332 on the left side of the tongue are respectively connected to the tongue top contact end 331 and the connecting section on the left side of the tongue; the tongue top contact end 331 on the left side of the tongue is an arc-shaped surface wrapped structure, and the stretching reference plane of the arc-shaped surface is perpendicular to the left line of the tongue.

A groove is provided at the end of the tongue right tongue top insertion section 343, and a magnet 14 is provided in the groove, which is inserted into the groove of the force transmission rod 2. The structural design of the tongue tops on the left and right sides of the tongue allows the force measurement of the four tongue parts to be completed in the same posture, reducing human influence, standardizing measurement influencing factors, and improving measurement accuracy.

[0041] For example, because the tongue is flexible and changeable, the same force applied to the tip, middle, and both sides of the tongue produces different deformations. If the force is applied improperly or the fixation is not firm, the tongue is likely to slide off the contact surface of the tongue top assembly 3. For this reason, the utility model designs tongue top assemblies 3 of different shapes according to different measurement points, so that the tongue is not easy to slide off even if sufficient force is applied. The cross-sectional area of ​​the telescopic section of the tongue top assembly 3 is smaller than the contact end of the tongue top assembly, so that the rest of the tongue does not contact the parts other than the top contact end during measurement, reducing the measurement error.

[0042] In actual applications, the size and shape of the tongue top component 3 and the alveolar socket are determined according to the conditions of the measured population, and can be designed for adult groups, adolescent groups, and children groups to ensure accuracy and efficiency during actual application.

[0043] like Fig. 9As shown, in this embodiment, the tongue area is divided into the tip, middle, left and right of the tongue, and the contact ends of the corresponding tongue top components are respectively in contact with the corresponding tongue muscles. After completing the segmentation study of the entire tongue muscle, after a large amount of data statistics, the health level curves of the tongue muscles in different partitions are established, which helps to improve the efficiency and accuracy of doctors' on-site diagnosis.

[0044] As an optional embodiment, the tongue top assembly 3 is not limited to the four forms of tongue tip, tongue middle, and tongue sides, and can be designed in combination into a new structure, such as the tongue tip and tongue middle covering type, the tongue side and tongue tip covering type, the tongue middle and tongue sides covering type, the left tongue and the tongue tip and the tongue middle covering type, the right tongue and the tongue tip and the tongue middle covering type, the left tongue and the tongue tip covering type, the right tongue and the tongue tip covering type, the left tongue and the tongue middle covering type, the right tongue and the tongue tip covering type, the left tongue and the tongue middle covering type, the right tongue and the tongue middle covering type, etc.

[0046] like Figure 2 As shown, based on the detection device described in the utility model, the specific tongue muscle strength measurement includes the following steps:

[0047] When the normally open switch is pressed, the internal circuit is connected; the tongue top assembly 3 is acted upon by the force of the tongue, and the force is transmitted to the force-bearing end (i.e., the suspended end) of the weighing sensor 6, resulting in changes in component stress and strain, which in turn causes changes in the resistance of the strain gauge. The continuously changing value of the electrical signal is sent to the host computer. After receiving the electrical signal, the host computer extracts samples of the analog signal at fixed time intervals, and the sample value curve is displayed in real time and recorded in the database; the screen receives real-time data changes and displays the value.

[0048] Furthermore, before measuring, the main switch button 8 is pressed to reset the screen indication to zero. During measurement, the start and end points of the measurement are controlled by manually pressing the normally open switch button 11. The measurement time can be flexibly adjusted according to the measurement requirements and on-site conditions.

[0049] The measured data can be recorded in the "personal medical record". The measurement results can generate an overlay graph of multiple measurements, and can also generate a single measurement comparison graph of the four areas of the tongue based on real-time data.

[0050] Furthermore, the detection device described in the utility model can also be used to establish patient files, record and play the entire measurement process, record the force size of each contact area and the force-time curve characteristics, and analyze and collect statistical data.

[0051] Establish patient files for tongue muscle strength, record and play the entire measurement process, record the strength of each contact area and the force-time curve characteristics, facilitate statistics and analysis of data, and cooperate with medical staff to design treatment plans based on big data.

[0052] Exemplarily, outside the scope of the device, the data processing device and the device of the utility model realize data interaction through Bluetooth, and generate relevant curves in real time, and the coordinates of the curves are time and force. Before treatment, by observing the curve, the change of force over time can be intuitively obtained, and further the strength and duration of different tongue muscles of the patient can be reflected. During or after treatment, it can be repeatedly measured, thereby providing doctors with treatment directions or verifying treatment results.
