Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a multifunctional laryngeal gustatory vibration stimulation rehabilitation device. Background Art

[0002] Dysphagia refers to difficulty in swallowing that occurs at different sites caused by various reasons, mainly due to oral and laryngeal tissue lesions.

[0003] At present, for the vibration stimulation rehabilitation of dysphagia, it is basically mainly to stimulate the facial muscles and tongue with a vibrating rod. Or use a spoon to dip a little sour lemon juice on the patient's tongue to stimulate the patient's swallowing initiation.

[0004] The existing vibration stimulation rehabilitation device vibrates the larynx in a single direction, mainly up and down, resulting in incomplete vibration stimulation of the laryngeal tissue, slow rehabilitation, and poor effect. Summary of the Invention

[0007] In a possible technical solution, further, the vibration stimulation mechanism further includes: Drive shaft, engaged with the output shaft of the biaxial motor through gears; The vibration generator includes: Fixed box, provided with a plurality of through holes along the circumferential side; A plurality of piston cylinders, installed on the fixed box, and each piston cylinder corresponds to the position of the through hole; A rotating shaft, coaxially connected to the transmission shaft; An eccentric shaft, connected to the rotating shaft; A rotating disk, sleeved on the eccentric shaft away from the rotating shaft; Multiple pistons, correspondingly embedded in the piston cylinders; Multiple piston rods, circularly arrayed and installed in the fixed box to enclose a cavity for the rotating disk to rotate. The piston rods are connected to the pistons. When the eccentric shaft rotates, it drives the rotating disk to make a circular motion away from the axis of the rotating shaft, so as to make the piston rods push and pull the pistons to move inside the piston cylinders. Through the vibration transmission between the piston cylinders and the pistons to the second housing, the throat containing the second housing can feel the vibration in multiple directions, making the angle of vibration stimulation more comprehensive.

[0008] In a possible technical solution, further, the cooling mechanism includes: A cooling pipeline, installed in the first housing and having multiple hollow tubes; A heat conduction plate; installed on one side of the hollow tube; A semiconductor refrigeration chip, in contact with the surface of the heat conduction plate away from the hollow tube.

[0009] In a possible technical solution, further, a plurality of heat dissipation openings are provided on the periphery of the first housing; The cooling mechanism further includes: A servo fan, installed on one side of the semiconductor refrigeration chip in the first housing, for sucking in air or discharging hot air.

[0010] In a possible technical solution, further, a bracket is installed in the first housing; The cooling pipeline includes: A liquid extraction pipe, connected to the jacket; A micro water pump, installed on the bracket and connected to the liquid extraction pipe; A liquid discharge pipe, connected to the micro water pump; Two liquid collecting tanks, symmetrically installed in the first housing. Each liquid collecting tank has a cavity, and the liquid collecting tank is communicated with the liquid discharge pipe; Multiple hollow tubes, installed between the liquid collecting tanks to communicate the two liquid collecting tanks; A delivery pipe, connected to the liquid collecting tank away from the liquid extraction pipe.

[0011] In a possible technical solution, further, it further includes: Absorbent cotton, installed at the end of the second housing away from the first housing. The absorbent cotton has several holes for adsorbing the solution that stimulates the taste.

[0012] In a possible technical solution, further comprising: A silicone ring connects the first shell and the second shell.

[0013] In a possible technical solution, further, the total number of the piston cylinders is eight to ten, so as to maximize the multi-directional and multi-angle vibration effect on the throat, thereby stimulating recovery.

[0014] In a possible technical solution, further, the hollow tube is four parallel hollow pipes, and each hollow pipe is connected to the liquid collecting tank.

[0015] A multifunctional laryngeal taste vibration stimulation rehabilitation device, comprising: The present invention sets a laryngeal temperature stimulation mechanism and a laryngeal vibration stimulation mechanism to cooperate with each other, uses a micro water pump and a cooling pipe to cooperate with a semiconductor refrigeration plate, and transports the cooled coolant to the inside of the jacket located in the throat, stimulates the laryngeal tissue by means of alternating hot and cold temperatures, and generates multi-directional and multi-angle vibrations in the throat through a vibration generator, which stimulates the laryngeal tissue in a vibration manner, and plays a role in stimulating recovery. In addition, an absorbent cotton for absorbing the irritating solution is set to be located in the throat, further stimulating the patient's taste and stimulating the start of the swallowing reflex. This chemical stimulation is combined with mechanical vibration to form a multi-sensory synergistic effect, which significantly enhances the patient's neural response and the activation of the swallowing function.

[0016] The vibration stimulation of the laryngeal vibration stimulation mechanism of the present invention generates multi-directional and multi-angle mechanical vibrations through a vibration generator, which directly acts on the laryngeal tissue, can activate deep muscles and nerve endings, and improve the coordination and strength of the laryngeal muscles. Compared with a single vibration stimulation (such as traditional up and down jumping) that can only target muscle groups in a specific direction, the multi-directional vibration of the present device covers a wider laryngeal area, making up for the limitations of traditional methods. At the same time, taste stimulation further awakens the swallowing-related neural pathways through chemical signals, and the laryngeal tissue can be stimulated more comprehensively under the dual effects. The multifunctional laryngeal taste vibration stimulation rehabilitation device of the present invention shortens the rehabilitation process through comprehensive stimulation, especially for patients in the late stage of rehabilitation, by strengthening the initiation of swallowing through taste stimulation, the autonomous swallowing ability can be restored more quickly.

[0017] A multifunctional laryngeal taste vibration stimulation rehabilitation device, which also includes: A controller, installed inside the handle, and electrically connected to the cooling mechanism and the dual-axis motor respectively; A plurality of temperature sensors, embedded in the inner wall of the jacket and electrically connected to the controller, for obtaining temperature values ​​of a plurality of points in the jacket to calculate a temperature average; A vibration sensor, mounted on the inner wall of the second shell, electrically connected to the controller, and used to collect the three-axis acceleration of the second shell; An electromyogram sensor interface, installed on the first housing and electrically connected to the controller, is used to adjust the rotation speed of the biaxial motor according to the received electromyogram signal; A micro spray device, installed at the end of the second housing and electrically connected to the controller, is used to control the release dose of the taste solution of the micro spray device according to the electromyogram signal; A Bluetooth module, installed in the grip and communicatively connected to the controller.

[0018] A multifunctional throat taste vibration stimulation rehabilitation control method, which includes: Construct a throat taste vibration stimulation rehabilitation device as described above, and input the target temperature, the target vibration frequency range, and the taste stimulation interval time into the controller of the device; According to the environmental control parameters received by the controller, the environmental control parameters include the coolant temperature, the electromyogram signal, and the acceleration data of the second housing; Calculate the temperature average value based on multiple coolant temperatures, compare the temperature average value with the target temperature, and if the first preset condition is not met, control the output power of the thermoelectric cooler in the cooling mechanism until the first preset condition is met; Adjust the rotation speed of the biaxial motor according to the electromyogram signal; Based on the electromyogram signal and the taste stimulation interval time, control the release dose of the taste solution of the micro spray device; Calculate the amplitude and frequency based on the acceleration data of the second housing to output the detection result.

[0019] The present invention monitors the patient's reaction in real time through the electromyogram signal, temperature sensor, and vibration sensor. The vibration frequency and the release dose of the taste solution can be dynamically adjusted according to the electromyogram feedback to ensure that the stimulation intensity of both matches the patient's current state.

[0020] Specifically, when the root mean square value of the electromyogram shows an increase in muscle activity, the system may increase the vibration speed and trigger the release of the taste solution, forming a stronger stimulation synergy to further promote the remodeling of nerves and muscles.

[0021] Taste stimulation not only has a functional effect, but also can relieve the monotony of the patient to the simple mechanical stimulation through the sensory experience, improve the comfort and acceptance during the use process. The simultaneous action of vibration and taste avoids the possible decrease in adaptability caused by a single stimulation, enabling the patient to maintain sensitivity to the treatment during long-term use.

[0022] The synergistic effect of vibration stimulation and gustatory stimulation significantly enhances the nerve excitability, muscle activity, and triggering efficiency of swallowing reflex in laryngeal tissues through dual mechanical and chemical mechanisms. This multi-dimensional and personalized stimulation method not only makes up for the deficiencies of traditional single stimulation but also accelerates the rehabilitation process, improving the patient's treatment experience and effect. For patients with swallowing disorders, especially those who need intensive training in the later stage of rehabilitation, this comprehensive stimulation demonstrates outstanding clinical potential.

[0039] The cooling pipeline includes: A liquid extraction pipe 22 is connected to the jacket 24; A micro water pump 23 is installed on the bracket and connected to the liquid extraction pipe 22; A liquid discharge pipe 25 is connected to the micro water pump 23; Two liquid collection tanks 26 are symmetrically installed inside the first housing 21. Each liquid collection tank 26 has a cavity, and the liquid collection tank 26 is communicated with the liquid discharge pipe 25; Multiple hollow tubes 271 are installed between the liquid collection tanks 26 to communicate the two liquid collection tanks 26. In this embodiment, the hollow tubes 271 are four parallel hollow copper pipes, and each hollow copper pipe is connected to the liquid collection tank 26; A delivery pipe 272 is connected to the liquid collection tank 26 away from the liquid extraction pipe 22.

In this embodiment, 10 to 12 heat dissipation openings 211 are formed in an annular array on the rear side surface of the outer ring of the first housing 21 for the servo blower 210 to suck in air or discharge hot air.

[0043] It should be noted that in this embodiment, the multifunctional throat gustatory vibration stimulation rehabilitation device further includes: The adsorption cotton 4 is installed at the end of the second housing 31 away from the first housing 21. The adsorption cotton 4 has a plurality of holes for adsorbing the solution that stimulates the taste.

[0044] It should be noted that, in this embodiment, the multifunctional laryngeal taste vibration stimulation rehabilitation device further includes: The silica gel ring 35 connects the first housing 21 and the second housing 31.

[0045] It should be noted that, in this embodiment, the total number of the piston cylinders 332 is eight to ten to maximize the vibration effect on the larynx in multiple directions and angles, so as to play a role in stimulating rehabilitation.

[0046] Before the invention is used, the outer surfaces of the jacket 24 and the second housing 31 are disinfected with a disinfectant solution, and the outer surfaces of the jacket 24 and the second housing 31 are rinsed with pure water; With the patient's mouth open, hold the grip 1 and put the jacket 24 and the second housing 31 into the oral and laryngeal area of the patient. Then, by pressing the upper control button of the handle 11, the battery inside the handle 11 powers the micro water pump 23 and the semiconductor refrigerating sheet 29. The micro water pump 23 extracts the coolant in the inner wall chamber of the jacket 24 into the drain pipe 25 through the liquid suction pipe 22, and the drain pipe 25 conveys the coolant into the hollow pipe 271. The refrigerating end face of the semiconductor refrigerating sheet 29 contacts the hollow pipe 271, so as to cool the coolant flowing inside the hollow pipe 271. The cooled coolant will be conveyed to the inside of the jacket 24 along the conveying pipe 272, so as to achieve the purpose of stimulating the laryngeal tissue at low temperature.

[0047] During the process of temperature stimulation of the laryngeal tissue, for the patients in the initial stage of rehabilitation, the adsorption cotton 33 is not used. For the patients in the later stage of rehabilitation with good rehabilitation effects, the adsorption cotton 33 adsorbs edible solutions such as citric acid solution for stimulation, and the laryngeal tissue is stimulated by the stimulating solution. In the vibration stimulation stage, the servo biaxial motor delivers a rotational force to the transmission shaft 34, forcing the rotating shaft 333 inside the fixed box 331 to rotate. Since the eccentric shaft 334 is eccentrically arranged, when the eccentric shaft 334 rotates, it drives the rotating disk 335 to make a circular motion away from the axis of the rotating shaft 333, so that the piston rod 337 pushes and pulls the piston 336 to move inside the piston cylinder 332. The vibration between the piston cylinder 332 and the piston 336 is transmitted to the second housing 31, so that the larynx containing the second housing 31 can feel vibrations in multiple directions, making the angle of vibration stimulation more comprehensive.

[0048] The present invention cooperates by setting up a laryngeal temperature stimulation mechanism and a laryngeal vibration stimulation mechanism. Using a micro water pump and a cooling pipe in combination with a semiconductor refrigeration sheet, the cooled coolant is transported into the jacket located in the larynx, and the laryngeal tissue is stimulated by alternating hot and cold temperatures. At the same time, a vibration generator generates vibrations in multiple directions and at multiple angles in the larynx to stimulate the laryngeal tissue in a vibrating manner, playing a role in stimulating rehabilitation. In addition, an absorbent cotton for adsorbing the irritating solution is arranged at the larynx to further stimulate the patient's taste and trigger the start of the swallowing reflex. The combination of this chemical stimulation and mechanical vibration forms a multi-sensory synergistic effect, significantly enhancing the patient's nerve response and the activation of the swallowing function.

[0049] In the present invention, the vibration stimulation of the laryngeal vibration stimulation mechanism generates multi-directional and multi-angle mechanical vibrations through a vibration generator, directly acting on the laryngeal tissue, which can activate deep muscles and nerve endings, and improve the coordination and strength of the laryngeal muscles. Compared with a single vibration stimulation (such as traditional up and down jumping) that can only target muscle groups in a specific direction, the multi-directional vibration of this device covers a wider laryngeal area, making up for the limitations of traditional methods. At the same time, the taste stimulation further awakens the swallowing-related neural pathway through chemical signals, and under the dual action, it can more comprehensively stimulate the laryngeal tissue. The multi-functional laryngeal taste vibration stimulation rehabilitation device of the present invention shortens the rehabilitation process through comprehensive stimulation. Especially for patients in the later stage of rehabilitation, the swallowing start is strengthened through taste stimulation, and the ability to swallow independently can be restored faster.

[0055] It should be noted that the specific method of adjusting the rotational speed of the biaxial motor according to the myoelectric signal is as follows: The EMG interface collects the myoelectric signal (E(t)), and calculates the root mean square value of the myoelectric signal (E(t)) (unit: mV, , where the root mean square value of the myoelectric signal (E(t)) represents the muscle activity intensity; According to Adjust the rotational speed of the biaxial motor (unit: RPM), where is the reference rotational speed, represents the reference myoelectric value, which is determined by initial calibration; if (unit: mV), then increase If it is too high, then reduce it to the safe range (maximum 1000 RPM). In this embodiment, where: RPM.

[0056] It should be noted that the specific method of controlling the release dose of the taste solution of the microspray device based on the myoelectric signal and the taste stimulation interval time is as follows: According to the myoelectric signal (E(t)) collected by the EMG interface, calculate the root mean square value (unit: mV, ,; Judge whether the root mean square value exceeds the threshold value, or whether it reaches the taste stimulation interval time , if either of the two is satisfied, then trigger the spray device to release the dose sigmoid (unit: mL), where: mL (unit: mL, represents the reference release dose), (dimensionless, represents the sensitivity coefficient), . In this embodiment, the threshold value is 0.5 mV.

[0057] Calculate the amplitude and frequency based on the acceleration data of the second housing to output the detection result, specifically: The vibration sensor continuously collects the three-axis acceleration of the second housing (unit: m / s2); Calculate the combined amplitude (Unit: mm); Vibration main frequency Calculated by fast Fourier transform, FFT (Unit: Hz), where is the time series acceleration signal.

[0058] It should be noted that the smartphone application recommends optimization parameters according to historical data through the simple moving average method: to recommend optimization parameters, where is the historical parameter value at the i-th time, and the parameter values include environmental control parameters, such as temperature, rotational speed, electromyogram signal, etc., , representing the window size.

[0059] The present embodiment provides the following specific usage examples: In the initial stage of the patient's rehabilitation, set the input target temperature to 10 °C, the vibration frequency to 10 Hz, and no gustatory solution stimulation. The final output results of the device and the rehabilitation control method of this example are: the mm in the jacket, the root mean square value of the electromyogram signal mV, set the initial rotational speed RPM, which meets the preset conditions, and maintain the current control index for the initial rehabilitation of the patient.

[0060] In the later stage of the patient's rehabilitation, switch the temperature in the initial stage of rehabilitation to , set the vibration frequency to 30 Hz, minutes, calculate the released dose of the gustatory solution mL. Detect the root mean square value of the electromyogram signal mV, and according to the root mean square value of the electromyogram signal automatically adjust the rotational speed to 600 RPM.

[0061] Cleaning and maintenance: After use, disconnect the EMG patch, turn off the power, store the data in the application, and the battery is charged through the wireless charging stand The present invention monitors the patient's reaction in real time through electromyogram signals, temperature sensors and vibration sensors. The vibration frequency and the released dose of the gustatory solution can be dynamically adjusted according to electromyogram feedback to ensure that the stimulation intensity of both matches the patient's current state.

[0062] Specifically, when the root mean square value of the electromyogram shows an increase in muscle activity, the system may increase the vibration rotational speed and trigger the release of the gustatory solution to form a stronger stimulation synergy, further promoting nerve and muscle remodeling.

[0063] Taste stimuli (such as acidic solutions) not only have functional effects but also can relieve the monotony of patients towards simple mechanical stimuli through sensory experiences, improving the comfort and acceptance during use. The simultaneous action of vibration and taste avoids the possible decline in adaptability caused by a single stimulus, enabling patients to maintain sensitivity to treatment during long-term use.

[0064] The synergistic effect of vibration stimulation and taste stimulation, through dual mechanical and chemical mechanisms, significantly enhances the nerve excitability, muscle activity, and triggering efficiency of swallowing reflex of laryngeal tissues. This multi-dimensional and personalized stimulation method not only makes up for the deficiencies of traditional single stimulation but also accelerates the rehabilitation process and improves the treatment experience and effect of patients. For patients with swallowing disorders, especially those who need intensive training in the later stage of rehabilitation, this comprehensive stimulation demonstrates outstanding clinical potential.
