The invention of Patent Document 1 is to strengthen the oral muscle strength such as the tongue muscle by pressing the tongue trainer against the upper jaw with the tongue body, and has a structure for restricting the movement of the tongue body forward. Therefore, there is a problem that it is difficult to stimulate the pharyngeal contractile muscles controlled by the vagus nerve in the pharynx located in the back of the oral cavity because the movement of the tongue body to the front is restricted.

The invention of Patent Document 2 is a technique of pressing the tongue body with an instrument to promote saliva secretion, and it is difficult to stimulate the pharyngeal contractile muscle controlled by the vagus nerve in the pharynx located at the back of the oral cavity. There was a problem.

In the invention of Patent Document 3, an intraoral insertion portion having a length of 40 mm or more and 60 mm or less in the anterior-posterior direction, a thickness of 5 mm or more and 20 mm or less, and a width of 10 mm or more and 27 mm or less is inserted into the oral cavity, and the tongue body and the palatal fossa are formed. The space between the tongue and the palate is sufficiently filled in the width direction, and tongue pressure is applied to the palatal fossa through the intraoral insertion part, and the reaction is applied to the base of the tongue. It is a technique that closes the trachea by tilting the palate with force. However, there is a problem that it is difficult for the tongue body to move anteriorly and upwardly because the space in the oral cavity is filled with the intraoral insertion part, and therefore it is difficult to stimulate the pharyngeal contractile muscle in the pharynx, which is controlled by the vagus nerve. ..

The present invention has been conceived in view of these problems, and an object of the present invention is to provide an oral vagal nerve stimulator capable of stimulating the pharyngeal vagal muscle, which is a parasympathetic nerve and is controlled by the vagus nerve in the oral cavity, and a method of using the same. do.

The oral stray nerve stimulator according to claim 1 is an oral stray nerve stimulator that is inserted into the oral cavity to stimulate the stray nerve and does not include a mouse shield, and has a palatal fossa located behind the oral cavity. The user grips the intraoral insertion part, which has a stimulating length, has a rounded tip in a plan view, and is formed in a thin flat plate shape and has flexibility that can be inserted into the oral cavity. A grip portion for operating the intraoral insertion portion is provided, the oral cavity insertion portion can be held by the lips without being bitten by teeth, and the tongue is inserted into the oral cavity with the oral cavity insertion portion inserted into the oral cavity. It is possible to form a space in which the body can move anteriorly and upwardly , and the labial side of the oral cavity insertion portion is pushed up anteriorly and upwardly by using the tongue body while pressing the tongue body against the lower side of the oral cavity insertion portion. It is characterized in that it can push up the tip of the oral cavity insertion portion so that it can come into contact with the palatal fossa located behind the oral cavity.

According to the first aspect of the present invention, the user inserts the oral stray nerve stimulator into the oral cavity to a position where the anterior end reaches the palatal fossa in a plan view, and holds the oral stray nerve stimulator between the lips without biting with the teeth. While swallowing saliva, while moving the tongue body anteriorly and upwardly, the posterior part of the tongue body is raised upward so that the anterior end of the oral stray nerve stimulator is brought into contact with the palatal fossa. Repeatedly move forward and upward, raise and relax the back, and swallow. The pharyngeal contractile muscle relaxes due to the large movement of the tongue body forward and upward, and when the tongue body returns to its original state due to relaxation, the pharyngeal contractile muscle contracts due to the reaction. As a result, the bioelectric signal is afferently transmitted from the pharyngeal contractile muscle to the brain, and the bioelectric signal is efferently transmitted from the brain to the whole body. As a result, the neurotransmitter acetylcholine is secreted from the nerve endings, resulting in dilation of blood vessels and increased blood flow. When blood flow increases, the body temperature rises and the movement of white blood cells that control immunity is activated, which has the advantageous effect of increasing immunity. For example, when the body temperature rises by 1 ° C., the immunity increases by 18% to 30%.

When the insertion position and posture of the oral vagal nerve stimulator are determined and held between the lips, both hands can be freed for training, so that training can be performed while performing various tasks such as cooking, that is, It has the effect of being able to train while doing so. Also, even if you wear a mask, it is not bulky and inconspicuous, so you can train even when you go out.

It is the outline right side view of the oral vagal nerve stimulator of this invention. It is explanatory drawing of the chanting which moved the tongue body anteriorly and upward using the intraoral vagal nerve stimulator of the present invention. It is explanatory drawing of the state immediately after inserting the oral vagal nerve stimulator of this invention into the oral cavity. It is a flow chart of how to use an intraoral vagal nerve stimulator.

As shown in FIG. 4 or 5, the oral vagal maneuver 1 of the present invention is the oral vagal maneuver 1 while moving the tongue body 10 forward and upward when inserted into the oral cavity and swallowing saliva. It is a device that can enhance immunity by repeatedly performing the operation of pushing up the tip of the tongue until it comes into contact with the palatal fossa 12, swallowing saliva, and relaxing the tongue body 10.

As shown in FIGS. 1 to 3, the oral stray nerve stimulator 1 of the present invention is an oral stray nerve stimulator 1 that is inserted into the oral cavity 5 to stimulate the stray nerve and can stimulate the palatal fossa 12. The user grips the intraoral insertion portion 2 which has a long length, has a rounded tip in a plan view, and is formed in a thin flat plate shape and has flexibility that can be inserted into the oral cavity 5. a gripping portion 3 for operating the intraoral insertion portion 2, provided with, the oral cavity insertion portion 2 can be clamped by the lip 15 without chewing teeth 16, the oral cavity insertion portion 2 in a state of being inserted into the oral cavity It is possible to form a space in the oral cavity 5 in which the tongue body 10 can be moved forward and upward.

As shown in FIGS. 1 to 3, the intraoral stray nerve stimulator 1 includes an intraoral insertion portion 2 which is a portion to be inserted into the oral cavity 5, and a grip portion which is gripped by the user and operates the intraoral insertion portion 2. 3 and an insertion blocking portion 4 for blocking the insertion with the lip 15 are provided so that the intraoral insertion portion 2 is not accidentally inserted deep into the throat.

The oral vagal nerve stimulator 1 is integrally molded from a flexible material such as silicon, and the degree of bending can be changed by changing the thickness. For example, the intraoral insertion portion 2 to be inserted into the oral cavity 5 has a thickness of about 2 to 3 mm to facilitate bending, and the insertion blocking portion 4 and the grip portion 3 outside the lip 15 have a thickness of about 4 to 5 mm. It is made a little stiff to make it easier to grip and insert.

The grip portion 3 has a flat plate shape of a thin plate, can be easily picked by a finger, and can be easily operated such as tilting the intraoral insertion portion 2. The form of the grip portion 3 is not limited to a flat plate shape, and any form may be used as long as the orientation and insertion length of the inserted intraoral insertion portion 2 in the oral cavity 5 can be manipulated.

The insertion blocking portion 4 is a stopper provided for ensuring safety so that the insertion blocking portion 4 is not accidentally pushed too far into the oral cavity 5. The shape is, for example, an arc shape having a size close to a substantially arc shape of the outer peripheral surface of the lips 15 so as to follow the outer shape of the lips 15 and to be easily gripped by the lips 15, and the grip portion 3 A convex portion is formed on the side, and a concave portion is formed on the side of the intraoral insertion portion 2. The form of the insertion blocking portion 4 may be any form as long as it allows insertion to the palatal fossa 12 in the oral cavity 5.

The intraoral insertion portion 2 has a length capable of stimulating the palatal fossa 12, has a rounded tip in a plan view, and is formed in a thin flat plate shape so as to be insertable into the oral cavity 5. doing. By making the tip portion rounded, the human body is prevented from being damaged when the tip portion hits a portion in the oral cavity 5 due to the insertion action. In addition, the shape-changing parts are all rounded without forming corners so that the human body is not damaged when the tip portion hits the part in the oral cavity 5 by the insertion action.

By forming the intraoral insertion portion 2 into a thin and flexible flat plate having a thickness of about 2 to 3 mm, a large space can be secured even if the intraoral insertion portion 2 is inserted into the oral cavity 5. The intraoral insertion portion 2 can be easily flexed anteriorly and upwardly by the tongue body 10 which is moved anteriorly and upwardly, and a large structure which hinders the anteriorly upward movement of the tongue body 10 is further formed on the lip 15 side. Since it is only a thin plate, the tongue body 10 can be largely moved forward and upward. In addition, since the tongue body 10 is easily moved forward and upward and returned, it is unlikely to interfere with the swallowing movement when swallowing saliva.

Further, since the oral insertion portion 2 can be sandwiched between the lips 15 without being bitten by the teeth 16, the length in the height direction in the front side of the oral cavity 5 when the oral insertion portion 2 is bitten by the teeth 16 When the intraoral insertion portion 2 is sandwiched only by the lips 15 with a space between the teeth 16 in the vertical direction, the length in the height direction on the anterior side in the oral cavity 5 is longer. As a result, the length in the height direction on the anterior side in the oral cavity 5 can be lengthened, a large space can be formed on the anterior side in the oral cavity 5, and the tongue body 10 can be largely moved forward and upward.

Further, the intraoral insertion portion 2 can be easily pushed up by the tongue body 10 while the rear part of the tongue body 10 is largely moved forward and upward, and the shape of the lower surface of the palatal fossa 12 can be easily pushed up, so that no pain is felt. Although it is difficult to bring the posterior portion of the tongue body 10 into direct contact with the lower surface of the palatal fossa 12, the lower surface of the palatal fossa 12 can be pushed by performing the process via the intraoral insertion portion 2.

When the intraoral insertion portion 2 is used to push the posterior portion of the tongue body 10 toward the lower surface of the palate fossa 12 from below, the posterior portion of the tongue body 10 is raised, but the epiglottis blocks the trachea due to the reaction, so that aspiration can be prevented. When the intraoral vagal nerve stimulator 1 is used, it is necessary to prevent aspiration because it swallows saliva. In addition, the movement of moving the tongue body 10 forward and upward so as to push up the palatal fossa 12 also leads to prevention of aspiration.

As shown in FIG. 5, the intraoral insertion portion 2 is inserted into the oral cavity 5 in a state where the tongue body 10 is located below and there is nothing in contact with the lower surface of the palatal fossa 12, and as shown in FIG. In addition, while moving the tongue body 10 forward and upward in the direction of arrow A, moving the tongue body 10 in the direction of arrow B so as to push up the intraoral insertion portion 2 until it comes into contact with the lower surface of the palatal fossa 12 is the tongue body 10. The movement will be moved forward and upward as much as possible. As a result, the tongue base 11 is pulled forward and upward, and the pharyngeal contractile muscle 13 relaxes and expands accordingly, and then when the tongue body 10 is relaxed and returned to its original position, the pharyngeal contractile muscle 13 contracts in reaction. Return to the original.

In order to repeat while being aware of the cycle of contracting and relaxing the pharyngeal contractile muscle 13, it is necessary to move the tongue body 10 significantly forward and upward, and the oral vagal nerve stimulator 1 of the present invention. The thin, flat plate-shaped form of the oral insertion portion 2 is a highly suitable form because it does not interfere with the large anterior-upward movement of the tongue body 10. That is, since the oral cavity insertion portion 2 is not bitten by the teeth 16 but is sandwiched only by the lips 15 by increasing the distance between the upper and lower teeth 16, the height of the space in the oral cavity 5 can be increased, and the oral cavity insertion portion 2 can be increased. Since the tongue body 10 has a flexible and thin flat plate shape, the oral cavity insertion portion 2 can be easily bent forward and upward by the force of the tongue body 10, so that the tongue body 10 can be largely moved forward and upward. ..

The vagus nerve is activated by the normal activity of the pharyngeal contractile muscle 13 relaxing and contracting. Since the vagus nerve is distributed throughout the body, the pharyngeal contractile muscle 13 afferently transmits a bioelectric signal to the brain, and the brain efferently transmits a bioelectric signal to the whole body. As a result, acetylcholine is secreted from nerve endings throughout the body, resulting in dilation of blood vessels throughout the body and increased blood flow throughout the body.

When blood flow increases throughout the body, the body temperature rises and the movement of white blood cells that control immunity is activated, so immunity increases. For example, when the body temperature rises by 1 ° C., the immunity increases by 18% to 30%.

Next, a method 20 of using the intraoral vagal nerve stimulator will be described. As shown in FIG. 6, the method 20 of using the intraoral stray nerve stimulator has a length capable of stimulating the palatal fossa 12, has a rounded tip in a plan view, and is formed in a thin flat plate shape. The sandwiching step 21 in which the flexible oral insertion portion 2 that can be inserted into the oral cavity 5 is inserted into the oral cavity 5 and sandwiched between the lips 15 without being bitten by the teeth 16 and the tongue body 10 are moved forward and upward. While protruding, the oral insertion portion 2 is pushed up at the rear part of the tongue body 10 until it comes into contact with the palatal fossa 12, and then a series of operations of relaxing the tongue body 10 and a swallowing operation of swallowing saliva are repeated in parallel. The tongue body moving step 22 to be performed is provided.

In the step 21, holding the oral cavity insertion portion 2 between the lips 15 without being bitten by the teeth 16 can secure a larger space in the oral cavity 5 than when the teeth 16 are bitten, and thus the tongue body 10. The movement can be increased. By moving the tongue body 10 forward and upward, the pharyngeal contractile muscle 13 is pulled, relaxed and expanded.

When the tongue body 10 is largely moved forward and upward and then relaxed so as to return the tongue body 10 to its original position, the pharyngeal contractile muscle 13 contracts in reaction.

After performing the pinching step 21, only the tongue body moving step 22 was repeated 6 times in 30 seconds continuously for 3 to 5 minutes. The results are shown in Table 1. In Table 1, the implementation time means the time to execute the tongue body movement step 22, and the body surface temperature indicates the result of detecting the temperature of the body surface by thermography.

From Table 1, although it varies depending on the person, if the tongue body movement step 22 of the method 20 of using the oral vagal nerve stimulator 20 is carried out for 3 to 5 minutes, the temperature of the body surface becomes 1 ° C. to 2 ° C. or 2 ° C. to 3 ° C. It was obtained to rise. For a while, for example, the experience changed depending on the person, but the body remained warm for about 30 minutes to about 1 hour.

In general, leukocytes are activated when the temperature is 37 ° C to 38 ° C, and enzymes in the body are also activated when the temperature is 37 ° C. Therefore, the average body temperature of a person is 36.5 ° C. By practicing the method 20 of using the vagal nerve stimulator, leukocytes are activated and enzymes are also activated. When white blood cells are activated, immunity increases.

Therefore, the pharyngeal contractile muscle 13 can be made to function normally by repeatedly performing the training using the oral vagal nerve stimulator 1 of the present invention and repeatedly stimulating the pharyngeal contractile muscle 13. Therefore, if the training is performed before going out or when returning home, for example, a preventive effect can be obtained by immunity against various bacteria.

Further, since the pharyngeal contractile muscle 13 is controlled by the vagus nerve, which is also a parasympathetic nerve, a relaxing effect can be obtained. Therefore, for example, when refraining from a tense situation such as an interview or a presentation, training using the oral vagal nerve stimulator 1 of the present invention can be carried out before that to relax and face the situation.
