The valve core is reset under the action of the elastic member so that it contacts the annular protrusion to form a seal; Turn the knob to rotate the limit rod away from the first protrusion and rotate the second protrusion to the end position of the limit slot. This step is only performed at the beginning of each rehabilitation training; Place the occlusal part of the dental tray into the patient's mouth so that the upper and lower teeth of the patient are fixed in the alveolar occlusion corresponding to the occlusal part; Pressing the power switch starts the micro air pump device, which draws in outside air from the air pump inlet, sends it into the hose from the air pump inlet, and injects it into the air bag through the air inlet channel of the base plate to expand the air bag. During the expansion of the air bag, it pushes the second connecting arm to rotate around the pivot axis between it and the base plate, thereby driving the dental tray to open, and then lifting the patient's mouth to open.

The valve core separates from the annular protrusion, and the air in the airbag passes through the air inlet channel, the exhaust channel, and the air inlet cavity in sequence, and is finally discharged from the air outlet hole of the air outlet cavity. As the air is discharged, the airbag gradually contracts, and the supporting effect on the second connecting arm gradually weakens. Under the biomechanical action of the patient's oral muscles, the upper and lower jaw tooth components are displaced toward each other, thereby realizing the closing movement of the dental treatment tray; At the moment when the first bump is separated from the second bump, the signal transmitting module generates and transmits a second electrical signal; obtains the second electrical signal, stops timing based on the second electrical signal, obtains a timing result, verifies the number of valid training times based on the timing result, counts the number of training times if the verification passes, otherwise does not count, and sends the training number statistics and the timing result to a designated display window for display; The method for verifying the effective number of training times according to the timing results is: ; in, t 1 is the timing result, in seconds; t 0 is the preset duration in seconds; like , the verification passes, otherwise the verification fails.

[0016] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0017] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0018] As described in the background technology, when adjusting the trainer, it is often necessary to operate the locking part, sliding assembly and elastic part at the same time. For patients who are undergoing occlusion training, the operation is extremely inconvenient and affects the continuity of the training. On the other hand, some patients are unable to open their mouths independently or can only open them to a small extent due to oral diseases. During the training process, they need to overcome a large resistance to oral opening. Most existing technologies rely on manpower to overcome this resistance. Long-term training can easily make patients feel tired, reduce training compliance, and increase the workload of medical staff, which is not conducive to the effective implementation of rehabilitation training.

[0019] Example 1: Therefore, in order to solve the above technical problems existing in the prior art, this embodiment provides an oral rehabilitation training device, such as Figure 1 As shown, the training device includes a trainer 200, such as Figures 2-4 As shown, the trainer includes: Substrate 240, such as Figure 12 As shown, an air inlet channel 244 and an air outlet channel 245 are provided inside the substrate, and the air inlet channel is connected to the air outlet channel. Figure 11 As shown, a first connecting portion 241 and a second connecting portion 242 are provided on the upper and lower surfaces of the substrate; The dental tray 210 is provided with two groups, and the two groups of dental trays are arranged opposite to each other up and down. Figure 9 As shown, the two sets of dental trays each include an occlusal portion 212 and a connecting rod 211, wherein the occlusal portion is fixedly connected to one end of the connecting rod, and the surface of the occlusal portion has a tooth groove 213 that matches the human tooth portion; A first connecting arm 220, one end of which is pivotally connected to the first connecting portion of the base plate, and the other end of which is pivotally connected to an end of the connecting rod away from the engaging portion; a second connecting arm 280, which is arranged parallel to the first connecting arm, and has one end pivotally connected to the second connecting portion and the other end pivotally connected to the middle portion of the connecting rod; An airbag 270, which is disposed between the two sets of second connecting arms and is fixed to the two sets of second connecting arms, and is connected to the air outlet of the air inlet channel via a hose; An air intake connector 250, which is provided at the air inlet of the air intake passage; An air release valve 260 is mounted on one side of the substrate corresponding to the air outlet of the exhaust channel; The training device further comprises a micro air pump device 100 , which is connected to the air inlet connector via a hose.

[0020] Specifically, this embodiment works through a micro air pump device to continuously inject air into the airbag to expand the airbag. During the expansion of the airbag, the second connecting arm will be pushed to rotate around the pivot axis between it and the base plate, thereby driving the dental tray to open, and then lifting the patient's mouth to open. When the patient's mouth is opened to a preset degree, the micro air pump device stops working, keeps the mouth open for a preset time, and then opens the air release valve. The air in the airbag passes through the air inlet channel and the exhaust channel in turn, and is finally discharged from the air release valve. As the air is discharged, the airbag gradually contracts, and the supporting effect on the second connecting arm gradually weakens. Under the biomechanical action of the patient's oral muscles, the upper and lower jaw tooth components are displaced toward each other, thereby realizing the closing movement of the dental treatment tray.

[0021] This embodiment uses a micro air pump to inflate the airbag to expand the airbag, thereby opening the dental tray, and automatically overcoming the patient's oral opening resistance, reducing muscle fatigue caused by traditional manual operation, and pressure release can be achieved through the air release valve. There is no need to synchronously operate the locking part and the elastic part, which improves the convenience of using the training device. The pivotally connected first and second connecting arms form a parallel linkage mechanism, which improves the stability of the movement trajectory of the dental tray.

[0022] Optional, such as Figure 13 、 14 As shown, the deflation valve includes: An exhaust tube 261 is threadedly connected to the base plate. The exhaust tube has an air inlet cavity 269 and an air outlet cavity 262. A radially extending annular protrusion is provided at the connection point between the air outlet cavity and the air inlet cavity. An air outlet hole 267 is provided on the inner wall of the air outlet cavity near the air inlet cavity. A fixing block 264, which is fixed in the air inlet cavity; A valve core 263, which is in sliding engagement with the fixed block. The valve core is connected to the fixed block via an elastic member 265, and contacts the annular protrusion to form a seal. The plug-in part 268 has one end inserted into the air outlet cavity and is threadedly connected to the exhaust pipe. A resistance part 266 is provided at the end of the plug-in part inserted into the air outlet cavity, and the resistance part corresponds to the valve core.

[0023] Specifically, a screw joint is processed on the substrate side corresponding to the position of the air outlet of the exhaust passage, and an inner thread matching the screw joint is processed on the inner wall of the air inlet cavity of the exhaust cylinder, and the exhaust cylinder is connected and fixed through the thread cooperation of the exhaust cylinder and the screw joint, so that the air inlet cavity is connected with the air outlet of the exhaust passage, and in this embodiment, the fixing block is sleeved on one end of the valve core, and the elastic member can be a spring, and the spring is partially sleeved on the outer side of the valve core and partially wrapped in the fixing block. Rotate the plug-in part to make the abutting part move towards the valve core end of the air outlet cavity, and in the process of movement of the abutting part, the abutting part contacts the valve core and extrudes the valve core to move away from the annular protrusion end of the air inlet cavity, the valve core is separated from the annular protrusion and the spring is compressed, at this time the air inlet cavity is connected with the air outlet cavity, and the air in the air bag is sequentially discharged from the air inlet passage, the exhaust passage, the air inlet cavity, and finally the air outlet hole of the air outlet cavity.

[0024] In this embodiment, the valve core-ring protrusion sealing cooperation structure is adopted, and the displacement amount of the valve core is controlled through the abutting part when the plug-in part is rotated, so that the air bag deflation speed is adjusted.

[0025] Optionally, as shown in Figures 2-4 The limiting structure 230 is integrally fixedly installed on the base plate, as shown in Figure 7 The limiting structure includes a limiting plate 231 fixed on the base plate, and a limiting groove 231A is formed in the limiting plate, as shown in Figure 10 A first protrusion 221 is arranged on the side of the first connecting arm corresponding to the limiting groove, the first protrusion is embedded in the limiting groove, and the limiting groove extends along the movement track of the first protrusion.

[0026] Through the embedded cooperation of the first protrusion and the limiting groove, the movement track of the first connecting arm is constrained in a predetermined path, and the risk of abnormal stress on the joint is reduced. The rigid constraint of the limiting plate can limit the unintended large-angle opening movement, prevent secondary injury caused by excessive stretching of the joint capsule, and is particularly suitable for the early rehabilitation stage after surgery.

[0027] Optionally, as shown in Figure 7 The limiting structure further includes: A limiting rod 232, one end of the limiting rod 232 is pivotally connected with the limiting plate, as shown in Figure 8 A second protrusion 232A is arranged on the other end of the limiting rod, and the second protrusion 232A is embedded in the limiting groove; A worm gear structure 233 is integrally fixedly installed on the limiting plate, a worm gear of the worm gear structure is installed on the pivot shaft of the limiting rod and the limiting plate, and a knob is installed at one end of the worm.

[0028] The embodiment controls the angle of the limiting rod by adopting a worm gear transmission mechanism, realizes the control of the mouth opening training range through the position change of the second protrusion in the limiting groove, meets the progressive training needs of different rehabilitation stages, and replaces the traditional multi-bolt adjustment mode by single-point control of the knob. The medical staff can complete the adjustment with one hand, and the self-locking characteristics of the worm gear can reduce the displacement of the limiting position during training.

[0029] In addition, as Figure 5 shown, the micro air pump device includes a device body 110, on which an air pump air inlet 120 and an air pump air outlet 130 are arranged, and a power switch 140 is further arranged on the device body.

[0030] In addition, the hose connecting the micro air pump device and the training device can be connected through interference fit with the air pump air outlet and air inlet connector.

[0031] Embodiment 2: Because the same mouth opening action needs to be repeated many times during each set of rehabilitation training, but during training, the patient will have counting errors during training, and at the same time, the patient will end the single action ahead of time.

[0032] Therefore, in order to solve this technical problem, the embodiment improves on the basis of embodiment 1, and in the embodiment, a piezoelectric film is arranged on the second protrusion. The substrate is provided with a signal transmitting module 243, and the piezoelectric film is connected with the signal transmitting module. When the first protrusion contacts the second protrusion, the signal transmitting module generates and transmits a first electric signal. When the first protrusion is separated from the second protrusion, the signal transmitting module generates and transmits a second electric signal. The device body is further provided with a monitoring module 150, which is used to acquire the first electric signal, start timing based on the first electric signal, acquire the second electric signal, stop timing based on the second electric signal, and obtain a timing result. According to the timing result, the effective training times are verified. If the verification is passed, the training times are counted, otherwise, the training times are not counted. The training time counting result and the timing result are sent to a designated display window for display.

[0033] Specifically, the way of verifying the effective training times according to the timing result is: ; Among them, t 1 is the timing result, with the unit of seconds; t 0 is the preset duration, with the unit of seconds, which is set by human; If , the verification is passed, otherwise, the verification is not passed.

[0034] Specifically, the way of counting the times is: ; wherein, n m+1 is the number of rehabilitation training times in the first m +1 training; n m is the number of rehabilitation training times in the first m training; m is the number of rehabilitation training times; m ≥0, n m ≥0.

[0035] For example, in the first time of opening mouth action in a group of rehabilitation training, the patient sets t 0=3 seconds, the air bag expands to make the first protrusion contact the second protrusion, the piezoelectric film generates the first electric signal, the monitoring module starts timing, opens the exhaust valve, the air bag shrinks, the first protrusion and the second protrusion are separated to generate the second electric signal, the monitoring module stops and times, at this time the timing result is 3.2 seconds (the timing result is the patient's mouth opening maintenance time), at this time t 1=3.2> t 0=3, trigger count: n 1= n 0+1=0+1=1. When the patient only maintains 2.8 seconds, the monitoring module judges t 1=2.8< t 0=3, the counter remains 0 unchanged.

[0036] Through this embodiment, the number of qualified actions of the patient during training can be counted, so that the patient can master the training progress in real time.

[0037] Embodiment 3: The embodiment provides an oral rehabilitation training method, and the training method uses the oral rehabilitation training device described in embodiment 2, and the training method comprises the following steps: One end of the hose is connected with the air pump outlet of the micro air pump device, and the other end is connected with the air inlet connector of the base plate; The plug-in part is rotated to move the abutting part away from the valve core end of the air outlet cavity until the abutting part is separated from the valve core, and the valve core is reset under the action of the elastic member to contact the annular protrusion to form a seal; The knob is rotated to rotate the limiting rod away from the first protrusion, and the second protrusion is rotated to the end position of the limiting groove, and this step is only executed at the beginning of each rehabilitation training; The occlusal part of the dental tray is placed in the patient's mouth, and the patient's upper and lower teeth are fixed by occluding the tooth groove of the occlusal part; Press the power switch to start the micro-pump device, the micro-pump device inhales the air from the air pump inlet, sends it into the hose from the air pump inlet, injects it into the air bag through the air inlet channel of the base plate to make the air bag expand, and the second connecting arm is rotated around the pivot shaft of the base plate in the process of expansion of the air bag, so as to drive the tooth tray to open, and the patient's oral cavity is opened, and the first protrusion on the side of the first connecting arm moves along the limiting groove of the limiting plate in the process; When the patient's oral cavity is opened to the preset angle, the power switch is pressed again, and the micro-pump device stops working; The knob is rotated to move the limiting rod towards the first protrusion until the second protrusion contacts the first protrusion, and this step is only performed at the beginning of each rehabilitation training; When the first protrusion contacts the piezoelectric film on the second protrusion, the signal emitting module generates a first electric signal and sends it to the monitoring module, the monitoring module acquires the first electric signal, and starts timing based on the first electric signal; After the preset time, the plug-in part is rotated to move the abutting part towards the valve core end away from the air outlet cavity, so that the abutting part contacts the valve core and extrudes the valve core to move away from the annular protrusion end of the air inlet cavity, the valve core is separated from the annular protrusion, and the air in the air bag passes through the air inlet channel, the air outlet channel and the air inlet cavity in turn, and is finally discharged from the air outlet hole of the air outlet cavity. With the discharge of air, the air bag gradually shrinks, the support effect on the second connecting arm gradually decreases, and under the action of the biomechanics of the patient's oral muscle group, the upper and lower jaw tooth components are displaced towards each other, thereby realizing the closing movement of the tooth treatment tray; At the moment when the first protrusion and the second protrusion are separated, the signal emitting module generates a second electric signal and sends it; the second electric signal is acquired, the timing is stopped based on the second electric signal, and the timing result is obtained. According to the timing result, the effective training frequency is verified, if the verification is passed, the training frequency is counted, otherwise not counted, and the training frequency counting result and the timing result are sent to the specified display window for display; The way of verifying the effective training frequency according to the timing result is: ; Wherein, t 1 is the timing result, in seconds; t 0 is the preset duration, in seconds; If , the verification is passed, otherwise the verification is not passed; The way of counting the number is: ; Wherein, n m+1 is the rehabilitation training frequency counting result in the first m +1 training; n m is the rehabilitation training frequency counting result in the firstm a number of times of secondary rehabilitation training; m a number of times of rehabilitation training; m ≥ 0, n m ≥ 0.

9. An oral rehabilitation training method, characterized in that: The training method uses an oral rehabilitation training device according to any one of claims 6 to 8, and the training method includes: Connect one end of the hose to the air pump outlet of the micro air pump device, and the other end to the air inlet connector of the base plate; The plug-in part is rotated to move the abutment part toward the air outlet cavity away from the valve core end until the abutment part is separated from the valve core. The valve core is reset under the action of the elastic member so that it contacts the annular protrusion to form a seal; Turn the knob to rotate the limit rod away from the first protrusion and rotate the second protrusion to the end position of the limit slot. This step is only performed at the beginning of each rehabilitation training; Place the occlusal part of the dental tray into the patient's mouth so that the upper and lower teeth of the patient are fixed in the alveolar occlusion corresponding to the occlusal part; Pressing the power switch starts the micro air pump device, which draws in outside air from the air pump inlet, sends it into the hose from the air pump inlet, and injects it into the air bag through the air inlet channel of the base plate to expand the air bag. During the expansion of the air bag, it pushes the second connecting arm to rotate around the pivot axis between it and the base plate, thereby driving the dental tray to open, and then lifting the patient's mouth to open. During this process, the first protrusion on the side of the first connecting arm moves along the limit groove of the limit plate; When the patient's mouth opens to the preset angle, press the power switch again and the micro air pump device stops working; Turn the knob to rotate the limit rod toward the first protrusion until the second protrusion contacts the first protrusion. This step is only performed at the beginning of each rehabilitation training. When the first bump contacts the piezoelectric film on the second bump, the signal transmitting module generates a first electrical signal and sends it to the monitoring module. The monitoring module acquires the first electrical signal and starts timing based on the first electrical signal. After a preset time, the plug-in portion is rotated to move the abutment portion toward the air outlet cavity, close to the valve core end, so that the abutment portion contacts the valve core and squeezes the valve core to move toward the air inlet cavity, away from the annular protrusion end. The valve core separates from the annular protrusion, and the air in the airbag passes through the air inlet channel, the exhaust channel, and the air inlet cavity in sequence, and is finally discharged from the air outlet hole of the air outlet cavity. As the air is discharged, the airbag gradually contracts, and the supporting effect on the second connecting arm gradually weakens. Under the biomechanical action of the patient's oral muscles, the upper and lower jaw tooth components are displaced toward each other, thereby realizing the closing movement of the dental treatment tray; At the moment when the first bump is separated from the second bump, the signal transmitting module generates and transmits a second electrical signal; obtains the second electrical signal, stops timing based on the second electrical signal, obtains a timing result, verifies the number of valid training times based on the timing result, counts the number of training times if the verification passes, otherwise does not count, and sends the training number statistics and the timing result to a designated display window for display; The method for verifying the effective number of training times according to the timing results is: ; in, t 1 is the timing result, in seconds; t 0 is the preset duration in seconds; like , the verification passes, otherwise the verification fails.
