Specifically, the main control module includes a start-stop unit and a time control unit. The start-stop unit and the time control unit are electrically connected to the gas generator, the vibration generator 221, the heating component and the refrigerator 16. The swallowing training device also includes a cyclic transposition mechanism. The cyclic transposition mechanism includes a shell, a plurality of fixed components located in the shell, a first drive component that drives the fixed component to move back and forth, and a movable component that drives the shell to move.

[0037] It can be understood that the present invention is provided with a body 10, and a stimulation device 20 is provided in the body 10, wherein the stimulation device 20 includes a normal stimulation component, an odor stimulation component, a vibration stimulation component, a heat stimulation component, and a cold stimulation component, and the swallowing training device also includes a main control module and an operation screen 11 provided on the body 10; when the patient needs to perform swallowing training, the body 10 is pushed in front of the patient, and the corresponding stimulation component is selected according to the actual situation of the patient. For example, when the patient needs to perform odor stimulation training, the odor delivery tube is placed at the patient's throat, and the odor training mode is selected through the operation screen 11, and then Set the time through the time control unit and click start through the start-stop unit. The odor generator will operate within the set time and send the stimulating odor into the patient's throat through the odor delivery tube to enable the patient to perform swallowing training. During operation, the odor generator will stop operating when the set time is up or the medical staff actively turns it off. By setting up 5 stimulation components, there will be no shortage of equipment during the swallowing training process. The integrated swallowing trainer is easy to use, and through the electronic design, the appropriate training time can be set, making the training more systematic and improving the training effect.

[0038] Specifically, in this embodiment, a cavity is provided in the body 10, and a partition plate 14 is provided in the cavity. The partition plate 14 divides the cavity into multiple placement cavities 13. A plurality of pipe through holes 41 connecting the cavities are provided through the outer shell of the body 10. The gas generator is an air pump 15, and the air pump 15 is located in the placement cavity 13.

[0039] Furthermore, the gas delivery pipe includes a first tube body 24 and a first nozzle 241 connected to the first tube body 24. One end of the first tube body 24 away from the first nozzle 241 is connected to the air pump 15. The first tube body 24 passes through the pipe through hole 41 so that the first nozzle 241 is located outside.

[0040] It can be understood that when normal stimulation swallowing training is required, the first nozzle 241 is inserted into the patient's throat, and then the time is set through the operation screen 11, and start is clicked. The main control module will start the air pump 15 to supply air to the air path connected to the gas delivery tube, so that the gas can enter the patient's throat through the gas delivery tube to achieve normal stimulation swallowing training.

[0041] Furthermore, the odor delivery tube includes a second tube body 23, an odor material storage tube 232 provided in the middle section of the second tube body 23, and a second nozzle 231 connected to the second tube body 23. One end of the second tube body 23 away from the second nozzle 231 is connected to the air pump 15, the odor material storage tube 232 is communicated with the tube body, and the second tube body 23 passes through the pipe through hole 41 so that the second nozzle 231 is located outside.

[0042] As can be understood, when odor stimulation swallowing training is required, the second nozzle 231 is inserted into the patient's throat, and then the time is set through the operation screen 11. When the start button is clicked, the main control module will activate the air pump 15 to supply air to the air path connected to the odor delivery tube, allowing the gas to pass through the odor delivery tube, and then stimulate the odor material (vinegar in this application) in the odor material storage tube 232, entering the patient's throat to achieve odor stimulation swallowing training. The interior of the odor material storage tube 232 is connected to the second tube body 23, and a ball of cotton is placed inside. The cotton is then dipped in vinegar. In this way, the gas passing through the second tube body 23 and the odor material storage tube 232 will bring the vinegar smell to the patient's throat.

[0043] Furthermore, the connecting wire 22 passes through the pipe through hole 41, and one end of the connecting wire 22 is connected to the main control module via the vibration generator 221. The vibration generator 221 includes a vibration shell 2211, a sphere 2212 provided at the end of the vibration shell 2211, and an electric motor located in the vibration shell 2211, and the electric motor is connected to the connecting wire 22.

[0044] It can be understood that when vibration stimulation swallowing training is needed, the vibration shell 2211 is inserted into the patient's mouth so that the ball 2212 is located at the patient's throat, and then the time is set through the operation screen 11, and start is clicked. The main control module will power the electric motor in the vibration shell 2211 through the connecting wire 22, so that the vibration shell 2211 drives the ball 2212 to vibrate, so that the patient can achieve vibration stimulation swallowing training.

[0045] Furthermore, the heat transport pipe includes a third tube body 26 and a third nozzle 261 connected to the third tube body 26. The heating component is a heating wire wound around the third tube body 26. The heating wire is electrically connected to the main control module. One end of the third tube body 26 away from the third nozzle 261 is connected to the air pump 15. The third tube body 26 passes through the pipe through hole 41 so that the first nozzle 241 is located outside.

[0046] It can be understood that when thermal stimulation swallowing training is required, the third nozzle 261 is inserted into the patient's throat, and then the time is set through the operation screen 11. Click start, and the main control module will start the air pump 15 to supply air to the air path connected to the heat delivery tube, and will also start the heating wire to heat the heat delivery tube, so that the gas can pass through the heat delivery tube and the hot air enters the patient's throat to achieve thermal stimulation swallowing training.

[0047] Furthermore, the cold delivery pipe includes a fourth tube body 25 and a fourth nozzle 251 connected to the fourth tube body 25. One end of the fourth tube body 25 away from the fourth nozzle 251 is connected to the refrigerator 16. The refrigerator 16 is electrically connected to the main control module. The fourth tube body 25 passes through the pipe through hole 41 so that the fourth nozzle 251 is located outside.

[0048] It can be understood that when cold stimulation swallowing training is required, the fourth nozzle 251 is inserted into the patient's throat, and then the time is set through the operation screen 11, and start is clicked. The main control module will start the refrigerator 16 to send cold air to the cold delivery pipe, so that the cold air can enter the patient's throat through the cold delivery pipe to achieve cold stimulation swallowing training.

[0049] Preferably, the surfaces of the gas delivery pipe, the odor delivery pipe, the heat delivery pipe and the cold delivery pipe are all covered with thermal insulation cotton 40, and a universal wheel 12 is provided under the body 10.

[0050] It can be understood that the heat-insulating cotton 40 can maintain a constant temperature in each pipe, preventing cold air from affecting the pipe and thus affecting the effect of swallowing training.

[0051] Furthermore, the outer surface of the shell 31 is cylindrical, and the interior of the shell 31 is provided with a receiving space 39. The first driving component includes a sliding track 36 fixed to the interior of the receiving space 39, and a slider 37 slidably connected to the sliding track 36 (the sliding track and the slider are collectively referred to as a rodless electric cylinder). A plurality of the sliders 37 are arranged in an equidistant annular array. The fixed component includes a hollow cylindrical airbag 38 connected to the slider 37, and an air pump 35 for inflating the hollow cylindrical airbag 38. The middle of the hollow cylindrical airbag 38 A first through hole 40 is formed, and both ends of the shell 31 are respectively penetrated by a second through hole 34 that is consistent in size and collinear with the first through hole 40, and a third through hole 43 for the hollow cylindrical airbag 38 to pass through; the movable component includes a driven gear 41 arranged on the outer cylindrical surface of the shell 31, a rotating shell 32 rotatably arranged on the outer cylindrical surface of the shell 31, a servo motor arranged inside the rotating shell 32, and a driving gear 42 connected to the motor shaft of the servo motor, and the driving gear 42 is engaged with the driven gear 41.

[0052] It can be understood that the present application provides a cyclic switching mechanism that can facilitate the operation of doctors. For example, it is necessary to use cold stimulation, heat stimulation and normal stimulation alternately. The trigeminal nerve is activated by cold stimulation, the sensitivity of the throat is increased, and the swallowing reflex is promoted. Then, local blood vessels are dilated by heat stimulation to reduce the tension of the throat. Then, the swallowing reflex is induced by normal stimulation. If such alternation is performed entirely by holding the tube with one hand and operating the buttons with the other hand, it will be inconvenient, the time will be difficult to control, the sequence will be prone to errors, and the operation process will be slow. The stimulation type cannot be changed quickly and immediately, which will affect the corresponding stimulation effect to a certain extent.

[0053] In this application, the stimulation components to be used can be listed first, and then the corresponding tubes can be passed through the hollow cylindrical airbag 38 in order. A mark can be engraved on the thermal insulation cotton on the pipe. When the mark is parallel to the front end of the hollow cylindrical airbag 38, the air pump 35 can be started to inflate the hollow cylindrical airbag 38 so that the airbag can fix the corresponding tube. It should be noted that before fixing the tube, the hollow cylindrical airbag 38 also has enough air to support the volume, and the tube will also have friction in the hollow cylindrical airbag 38. Therefore, when fixing the three tubes, the previous tube will not slip when the next tube is fixed. After the hollow cylindrical airbag 38 is inflated, it can further clamp the tube. The initial position of the hollow cylindrical airbag 38 is against the housing 31, so that the first through-hole 40 and the second through-hole 34 are adjacent. At this time, the end of the hollow cylindrical airbag 38 away from the second through-hole 34 is also exposed to the outside through the third through-hole 43, making it convenient for the physician to pass the tube through the third through-hole 43, the first through-hole 40, and the second through-hole 34 in sequence. After the tube is fixed, the time, intensity, and other parameters of each stimulation are set. This can be achieved through programming. For example, if there are three hollow cylindrical airbags 38, by setting the three hollow cylindrical airbags 38 fixed stimulation components and setting the time and intensity, the mechanism can automatically change positions. The switching mechanism can be handheld, preferably mounted on the body. For example, the first one is cold stimulation. The doctor presses the switch 33 on the handle of the rotating shell 32, and the hollow cylindrical airbag 38 system drives the other two stimulation components except the first stimulation component to move in the direction away from the second through hole 34 according to the previously set content, leaving only the tube body of the first stimulation component in the front. The doctor inserts the cold stimulation tube into the patient's throat and starts the cold stimulation for a period of time. When the time is up, the cold stimulation tube is automatically retracted to make the cold stimulation tube leave the patient's mouth. The servo motor (located inside the rotating shell 32, not shown in the figure) The housing 31 is rotated to rotate the second heat stimulation component to the position of the cold stimulation component. This allows stimulation training to be performed sequentially according to the set content, improving operational efficiency. When setting the program, those skilled in the art can set the pause time according to their needs. For example, after the cold stimulation tube is retracted, the housing 31 will not rotate immediately. Instead, the operator must ensure that the tube has left the patient's throat before rotating. This avoids the tube rotating before leaving the mouth due to different throat depths between patients. This is all within the capabilities of those skilled in the art. This application only proposes structural and conceptual innovations. The servo motor, slider 37, air pump 35 and other electronic components can transmit signals via a wired or wireless method. Preferably, a wired method is used to simultaneously power and transmit signals. However, it should be noted that the rotation angle of the rotating shell 32 should be less than 360° and that it should be reversed immediately after rotating to 360° to avoid wiring entanglement.

[0054] In summary, the swallowing training device in the above embodiment of the present invention, by providing five stimulation components, can avoid equipment shortage during the swallowing training process. The integrated swallowing training device is easy to use, and through the electronic design, the appropriate training time can be set, making the training more systematic and improving the training effect.
