[0002] Research has found that some voice disorders don't involve organic damage to the vocal organs. Instead, they often present with dysphonia caused by psychological or muscle tension. For these patients, voice training is the primary treatment, and relaxation training is a crucial component. Specific muscle relaxation training is crucial, with the most important focus being on relaxing the laryngeal muscles to prevent laryngeal tension.

[0003] Relaxation of the laryngeal muscles mainly involves keeping the thyrohyoid muscle and cricothyroid muscle relaxed. Currently, relaxation training for the thyrohyoid muscle and cricothyroid muscle usually adopts manual relaxation. However, manual relaxation has problems such as patients' unclear grasp of muscle position, inability to accurately relax the muscles, and poor grasp of relaxation time and intensity, making it difficult to effectively relax the laryngeal muscles. In addition, during the pronunciation process, patients are not clear whether their pronunciation method will cause the laryngeal body to lift, thereby causing pronunciation fatigue.

[0004] Therefore, the existing method of using manual touch to relax the thyrohyoid muscle and cricothyroid muscle is difficult to clearly grasp the position and accurately relax, resulting in difficulty in effectively relaxing the laryngeal muscles. Summary of the Invention

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] This invention provides a laryngeal muscle stimulation device for voice disorders based on laryngeal muscle monitoring. It includes both mechanical and electrical stimulation. During stimulation, thin-film sensors monitor the position of the laryngeal muscles, and the feedback on the location of pressure determines how to perform mechanical or electrical stimulation. Mechanical stimulation primarily involves airbag compression, while electrical stimulation primarily involves direct stimulation using weak electrical pulses.

[0022] like Figures 1 to 4 As shown, the device includes a main unit 1 having a working surface 11 . The main unit 1 can be worn on the neck and throat so that the working surface 11 is attached to the throat for operation.

[0023] The working surface 11 is provided with an upper soothing airbag 2 and a lower soothing airbag 3, both of which are connected to the main unit 1 through a pipe 4, and the upper soothing airbag 2 is used to abut the thyrohyoid muscle area, and the lower soothing airbag 3 is used to abut the cricothyroid muscle area. The main unit 1 can independently control the inflation, deflation and pressing of the upper soothing airbag 2 and the lower soothing airbag 3 through the two pipes 4.

[0024] A plurality of pulse electrodes distributed according to the positions of the laryngeal muscles are arranged on the working surface (11).

[0025] The mechanical stimulation of the present invention is mainly achieved by setting an upper soothing airbag 2 on the host 1 to abut the thyrohyoid muscle area, and setting a lower soothing airbag 3 to abut the cricothyroid muscle area, so that after wearing the host 1 on the neck and throat, the upper soothing airbag 2 and the lower soothing airbag 3 can accurately abut the corresponding muscle positions. After manually operating the host 1, the host 1 can control the operation of the upper soothing airbag 2 and the lower soothing airbag 3, thereby accurately soothing and relaxing the thyrohyoid muscle and cricothyroid muscle.

[0026] Electrical stimulation is achieved by sending a weak electric current through a pulse electrode, which acts directly on the patient's skin surface to achieve the effect of bioelectric stimulation.

[0027] Both of the above stimulation methods require determining the position of the laryngeal muscles. A thin film sensor 5 is also provided on the working surface 11. The thin film sensor 5 is located between the upper soothing airbag 2 and the lower soothing airbag 3. The thin film sensor 5 is electrically connected to the host 1 to feedback the pressure position to the host 1. The host 1 can automatically select and control the inflation and deflation of the upper soothing airbag 2 and / or the inflation and deflation of the lower soothing airbag 3 according to the pressure position feedback from the thin film sensor 5.

[0028] The laryngeal muscle soothing and relaxing device of the present invention has the premise of manually operating the main unit 1 to control the relaxation. By arranging a thin film sensor 5 between the upper soothing air bag 2 and the lower soothing air bag 3, the thin film sensor 5 is attached to the skin of the throat, so that the pressure position can be obtained in time when the laryngeal body moves up and down, thereby obtaining the position of the laryngeal body. The main unit 1 can automatically control the operation of the upper soothing air bag 2 and the lower soothing air bag 3 according to the situation that the laryngeal body position is too high or the laryngeal body is lifted for too long, thereby soothing and relaxing the thyrohyoid muscle and cricothyroid muscle, reducing the pronunciation of the laryngeal body, and helping to correct or avoid incorrect pronunciation methods, and alleviate pronunciation disorders and pronunciation fatigue.

[0029] The thin film sensor 5 is a pressure sensor, which has the function of matrix detection, thereby obtaining the position of pressure change and the position of the throat.

[0030] Of course, if Figure 1 As shown, the working surface 11 is arc-shaped to match the shape of the throat, and the working surface 11 is provided with a soft cushion 111 , and the upper relief airbag 2 , the lower relief airbag 3 and the film sensor 5 are all arranged on the soft cushion 111 .

[0031] The use of the soft pad 111 enables the thin film sensor 5 to deform after being compressed, thereby reducing the resistance to the throat and improving wearing comfort.

[0032] Based on the above embodiment, the upper soothing airbag 2 and the lower soothing airbag 3 are used to soothe the thyrohyoid muscle and the cricothyroid muscle respectively. During the soothing process, it is necessary to soothe along the muscle direction to enhance the soothing effect. Based on this, a preferred embodiment of an upper soothing airbag 2 and a lower soothing airbag 3 is provided below.

[0033] Among them, Figure 2 、 Figure 3 As shown, the upper relief airbag 2 includes two upper airbags 21, which are symmetrically arranged on the working surface 11. The upper airbag 21 has multiple independent upper airbag cavities 211, and the multiple upper airbag cavities 211 can be independently inflated and deflated. One of the pipes 4 is connected to the two upper air bags 21 and is connected to a plurality of upper bag cavities 211; The host 1 can control the multiple upper bladder chambers 211 to be inflated and deflated in sequence through the pipeline 4 , and the deflation of the multiple upper bladder chambers 211 is delayed by the inflation.

[0034] Specifically, the upper airbag 21 has multiple upper airbag cavities 211, and the multiple upper airbag cavities 211 work independently. The pipeline 4 connects the main unit 1 and the multiple upper airbag cavities 211. The main unit 1 can control the multiple upper airbag cavities 211 to cyclically inflate and deflate in sequence through the pipeline 4, and the multiple upper airbag cavities 211 are attached to the thyrohyoid muscle area, thereby achieving back and forth soothing along the thyrohyoid muscle and improving the soothing effect.

[0035] Similarly, if Figure 2 、 Figure 3 As shown, the lower relief airbag 3 includes two lower airbags 31, which are symmetrically arranged on the working surface 11. The lower airbag 31 has multiple independent lower airbag cavities 311, and the multiple lower airbag cavities 311 can be independently inflated and deflated. Another pipeline 4 is connected to the two lower air bags 31 and is connected to multiple lower bag cavities 311; The host 1 can control the multiple lower bladder chambers 311 to be inflated and deflated in sequence through the pipeline 4 , and the deflation of the multiple lower bladder chambers 311 is delayed by the inflation.

[0036] The multiple lower cavities 311 of the lower airbag 31 work independently. The host 1 can control the multiple lower cavities 311 to cyclically inflate and deflate in sequence through the pipeline 4, and the multiple lower cavities 311 are attached to the cricothyroid muscle area, thereby achieving back and forth relief along the cricothyroid muscle and improving the relief effect.

[0037] During this process, the main unit 1 can control the air supply through the pipeline 4, thereby adjusting the relief intensity.

[0038] Since the upper airbag 21 and the lower airbag 31 are used to relieve the thyrohyoid muscle and the cricothyroid muscle respectively, and the extension directions of the thyrohyoid muscle and the cricothyroid muscle are inconsistent, in order to enable the upper airbag 21 and the lower airbag 31 to match the thyrohyoid muscle and the cricothyroid muscle, the following preferred embodiments are provided.

[0039] like Figure 1 、 Figure 2As shown, the upper airbag 21 is vertically arranged on the working surface 11. The outer wall of the upper airbag 21 is divided by multiple upper cavities 211 to form multiple upper convex walls. After the upper airbag 21 is attached to the thyrohyoid muscle area, the multiple upper convex walls are distributed along the thyrohyoid muscle. The lower airbag 31 is tilted on the working surface 11 , and the outer wall of the lower airbag 31 is divided by multiple lower cavities 311 to form multiple lower convex walls. After the lower airbag 31 is attached to the cricothyroid muscle area, the multiple lower convex walls are distributed along the cricothyroid muscle.

[0040] Specifically, since the thyrohyoid muscle is symmetrically distributed vertically on both sides of the larynx, the two upper air bags 21 are symmetrically distributed vertically, so that the upper air bags 21 can be pressed against and soothed along the direction of extension of the thyrohyoid muscle. Similarly, since the cricothyroid muscle is symmetrically distributed on both sides of the larynx and partially surrounds it, the two lower air bags 31 are symmetrically and obliquely distributed around it, so that the lower air bags 31 can be pressed against and soothed along the direction of extension of the cricothyroid muscle.

[0041] Of course, during the soothing process, the host 1 needs to control the operation of the upper sac chamber 211 and the lower sac chamber 311 through the pipeline 4, and the multiple upper sac chambers 211 and the multiple lower sac chambers 311 need to be inflated and deflated in sequence. Based on this, the following preferred embodiments are provided.

[0042] like Figure 2 、 Figure 3 As shown, each pipeline 4 is divided into an inflation pipeline 41 and a deflation pipeline 42, and the inflation pipeline 41 and the deflation pipeline 42 are both connected to the corresponding two upper air bags 21 or the two lower air bags 31; The inflation line 41 includes an inflation valve 411 having an air inlet and multiple air outlets. The multiple air outlets of the inflation valve 411 are all connected to an inflation tube 412, and the multiple inflation tubes 412 are respectively connected to the multiple upper cavities 211 of the two upper airbags 21 or the multiple lower cavities 311 of the two lower airbags 31. The deflation line 42 includes a deflation valve 421 having an air outlet and multiple air inlets. The multiple air inlets of the deflation valve 421 are all connected to deflation pipes 422, and the multiple deflation pipes 422 are respectively connected to the multiple upper cavities 211 of the two upper airbags 21 or the multiple lower cavities 311 of the two lower airbags 31. The inflation tube 412 and the deflation tube 422 are both dual-path manifolds, and each inflation tube 412 is connected to the upper cavities 211 on the corresponding two upper airbags 21 , or the lower cavities 311 on the two lower airbags 31 .

[0043] Specifically, the inflation valve 411 of one pipeline 4 is connected to the multiple upper airbag chambers 211 through multiple inflation tubes 412, and the inflation valve 411 of the other pipeline 4 is connected to the multiple lower airbag chambers 311 through multiple inflation tubes 412. When the host 1 supplies air to the inflation valve 411, the multiple upper airbags 211 and / or the multiple lower airbags 311 can be inflated in sequence by controlling the connection sequence between the air inlet and the multiple air outlets of the inflation valve 411. Similarly, the deflation valve 421 of one pipeline 4 is connected to the multiple upper airbag chambers 211 through multiple deflation pipes 422, and the deflation valve 421 of the other pipeline 4 is connected to the multiple lower airbag chambers 311 through multiple deflation pipes 422. When the main unit 1 inhales or exhausts air from the deflation valve 421, the air can be sequentially and cyclically extracted from the multiple upper airbags 211 and / or the multiple lower airbags 311 by controlling the opening sequence of the air outlet and the multiple air inlet ports of the deflation valve 421, thereby causing the multiple upper airbags 211 and / or the multiple lower airbags 311 to deflate in sequence. And since the deflation of multiple upper cavities 211 is delayed before inflation and the deflation of multiple lower cavities 311 is delayed before inflation, the host 1 controls the deflation valve 421 to lag the switching position of the inflation valve 411, that is, when the inflation valve 411 inflates the second upper cavity 211 or the second lower cavity 311, the deflation valve 421 simultaneously deflates the first upper cavity 211 or the first lower cavity 311, so that the upper airbags 21 and the lower airbags 31 are relieved in a waving manner along the direction of the muscles, thereby improving the relief effect.

[0044] Of course, in order to ensure that the multiple upper cavities 211 and the multiple lower cavities 311 are inflated and deflated in sequence, the inflation valve 411 and the deflation valve 421 need to be able to continuously and cyclically switch the inflation tube 412 and the deflation tube 422 respectively. Based on this, the following preferred embodiments are provided.

[0045] like Figure 3 、 Figure 4 As shown, the inflation valve 411 and the deflation valve 421 each include a valve body 45 , a valve core ball 451 is disposed in the valve body 45 , a motor is disposed on the valve body 45 , the motor shaft is connected to the valve stem of the valve core ball 451 , and the motor is controlled by the host 1 ; A right-angle through hole 452 is provided on the valve core ball 451. Both ends of the right-angle through hole 452 pass through the valve core ball 451, and one end of the right-angle through hole 452 is coaxial with the motor and faces the opposite direction of the motor. The multiple air outlets of the inflation valve 411 and the multiple air inlets of the deflation valve 421 are all distributed around the circumference of the valve body 45, and the air inlet of the inflation valve 411 and the air outlet of the deflation valve 421 are both arranged on the end side of the valve body 45 away from the motor. The host 1 can control the motor to rotate to drive the valve core ball 451 to rotate, so that the right-angle through hole 452 is connected to the air inlet and multiple air outlets of the inflation valve 411, or the air outlet and multiple air inlets of the deflation valve 421 in sequence.

[0046] Specifically, the motor adopts a stepping motor, which rotates the same angle each time. After each rotation of the valve core ball 451, its right-angle through hole 452 connects the air inlet and one of the air outlets, or the air outlet connects one of the air inlets. Therefore, when the motor rotates according to the set intermittent time, the air inlet is cyclically connected to multiple air outlets, or the air outlet is cyclically connected to multiple air inlets, thereby realizing sequential cyclic inflation into the multiple upper sac cavities 211 or the multiple lower sac cavities 311, or sequential cyclic extraction from the multiple upper sac cavities 211 or the multiple lower sac cavities 311 for deflation. Of course, an air pump 43 is provided in the main unit 1. Figure 3 As shown, the positive pressure end of the air pump 43 is connected to the air inlet of the inflation valve 411 through a pipe to pump air into the inflation valve 411, and the negative pressure end of the air pump 43 is connected to the air outlet of the deflation valve 421 through a pipe to extract air from the deflation valve 421.

[0047] Air is pumped into the inflation valve 411 through the positive pressure end of the air pump 43, and air is extracted from the deflation valve 421 through the negative pressure end of the air pump 43. The air pump 43 automatically starts and stops according to the intermittent frequency of the inflation valve 411 and the deflation valve 421, so that the inflation pipeline 41 and the deflation pipeline 42 form a loop through the air pump 43, and the inflation valve 411 and the deflation valve 421 are switched on synchronously to achieve synchronous inflation and deflation.

[0048] Since the accuracy of the air supply and pressurization of the air pump 43 is difficult to control and is often limited by manufacturing accuracy and manufacturing quality, improving the accuracy of the air pump 43 will bring higher costs, and insufficient accuracy will lead to insufficient control of the relief force. Based on this, the following embodiments are provided.

[0049] like Figure 3 As shown, a gas cylinder 44 is provided between the air pump 43 and the charging valve 411. The air inlet end of the gas cylinder 44 is connected to the air pump 43 via a one-way valve 431, and the air outlet end of the gas cylinder 44 is connected to the charging valve 411 via a regulating valve 441. Flow meters are provided at the positive pressure end of the air pump 43 and the outlet end of the regulating valve 411 , and the host 1 can control the pumping flow of the air pump 43 and the exhaust flow of the regulating valve 411 .

[0050] Specifically, a gas storage cylinder 44 is provided at the positive pressure end of the air pump 43, and the gas supply of the air pump 43 is pressurized and stored by the gas storage cylinder 44, so that the gas supply volume can be accurately controlled by the regulating valve 411, thereby achieving precise control of the relief intensity at a low cost.

[0051] It is worth noting that, in the manual relief mode, in order to make the upper airbag 21 and the lower airbag 31 automatically stop relief after the relief effect is achieved and avoid excessive relief, the following preferred embodiments are provided.

[0052] like Figure 2 As shown, the host 1 is provided with four myoelectric electrodes 12, the backs of the four myoelectric electrodes 12 are respectively attached to the surfaces of the two upper airbags 21 and the two lower airbags 31, and the host 1 is provided with four myoelectric sensors, and the four myoelectric electrodes 12 are respectively connected to the four myoelectric sensors; The upper airbag 21 presses the front of the myoelectric electrode 12 against the thyrohyoid muscle area for detection, and the lower airbag 31 presses the front of the myoelectric electrode 12 against the cricothyroid muscle area for detection; The host 1 automatically controls the start and stop of the upper airbag 21 and / or the lower airbag 31 based on the data detected by the myoelectric electrodes 12 and the myoelectric sensors.

[0053] Specifically, the myoelectric electrodes 12 are used in conjunction with the myoelectric sensors to accurately obtain the relaxation and fatigue state of the muscles, thereby determining whether the thyrohyoid muscle and cricothyroid muscle are fatigued. During the relaxation process, the inflation and deflation of the upper and lower air bags 21 and 31 do not affect the detection of the myoelectric electrodes 12, thereby improving the detection accuracy. Based on this, the upper and lower air bags 21 and 31 can be automatically stopped after the fatigue of the thyrohyoid muscle and cricothyroid muscle is relieved to avoid excessive relaxation. Moreover, the myoelectric electrodes 12 and the myoelectric sensors can also identify whether the thyrohyoid muscle and the cricothyroid muscle are fatigued, etc., thereby linking the host 1 and the upper airbag 21 and the lower airbag 31 in turn, so as to automatically relieve fatigue after regular voice use.

[0054] In the present invention, electrical stimulation is mainly used in conjunction with mechanical stimulation. For example, electrical stimulation can be used to stimulate muscles before, during, or after mechanical stimulation, which can cause the muscles at that location to contract or relax, thereby achieving further exercise, which is beneficial for correcting or avoiding incorrect pronunciation methods, alleviating pronunciation disorders and pronunciation fatigue, and improving recovery effects.

[0055] In an embodiment of the present invention, the pulse electrode has multiple electrodes, or at least one electrode. Taking into account the direct stimulation of human skin, the magnitude of its current is limited, and further taking into account the electrical stimulation of the laryngeal muscles in a relaxed state or in a moving state, the specific stimulation method can be determined by programming to match the host's control of mechanical stimulation.

[0056] Among them, the stimulation parameters are performed based on electric pulses with any shape, including but not limited to square, rectangular, sinusoidal or sawtooth shapes, and the pulse shape and current size can be determined according to the needs of electric stimulation.

[0057] It should be noted that the electrical stimulation in this embodiment is not limited to electrical stimulation when the laryngeal muscles are in a relaxed state.

[0058] Moreover, the prior art has conventionally taught how to apply electrical stimulation for muscle stimulation, and in this embodiment, no further explanation of the specific operation method (including but not limited to programming stimulation parameters, etc.) is given.

[0059] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
