Description

TECHNICAL FIELD The present invention relates to a nasal-cavity-insertion tool that is inserted into a nasal cavity.

Conventionally, there is known a nasal dilator that is inserted into the nasal cavity during sleep to dilate the nasal cavity, thereby relieving the symptoms of sleep apnea syndrome (for example, Patent Document 1). When such a nasal dilator is inserted into the nasal cavity, it stays inside the nasal cavity with the nasal cavity expanded, allowing air to be pumped through the nasal cavity into the respiratory tract.

Japanese Patent Publication No. 2006-501889

However, in the conventional nasal cavity insertion device, it is necessary to further expand the nasal cavity in order to send more air through the nasal cavity into the respiratory tract. However, it becomes difficult to insert the nasal insertion tool into the nasal cavity. On the other hand, when the entire nasal cavity inserting instrument is made small, it is easy to insert the nasal cavity inserting instrument into the nasal cavity, but the nasal cavity cannot be sufficiently expanded, so more air cannot be sent to the respiratory tract through the nasal cavity. In addition, the nasal cavity-insertion tool tends to fall out of the nasal cavity. Therefore, the conventional nasal-cavity-insertion tool has a problem that it is impossible to achieve both ease of insertion into the nasal cavity, sending more air into the nasal cavity, and prevention of falling out of the nasal cavity.

Moreover, the conventional nasal cavity inserter has a problem in obtaining a cosmetic effect.

An object of the present invention is to facilitate insertion into the nasal cavity, to send a sufficient amount of air into the respiratory tract through the nasal cavity when inserted into the nasal cavity, and to prevent falling out of the nasal cavity as much as possible. To provide a tool for inserting into a nasal cavity, capable of obtaining a cosmetic effect.

A nasal cavity-insertion instrument according to the present invention is a nasal cavity-insertion instrument to be inserted into a nasal cavity, comprising: a hollow part extending from one end to the other end; a tubular main body having a first opening that opens a hollow portion to the outside; and a second opening that opens the hollow portion to the outside at the end on the other end side; a pressing portion provided above the wall portion and extending from the one end side to the other end side.

When the nasal cavity-insertion instrument is inserted into the nasal cavity, the pressing part pushes the nasal muscle and the levator nasalis superioris upward to expand the nasal cavity, and the air taken into the hollow part from the second opening in the expanded nasal cavity is pushed into the second opening. It is discharged from the opening of 1 and sent into the respiratory tract, and pushes up the levator nasolabialis superior muscle to make the depth of the groove of the nasolabial fold shallower.

According to the present invention, it is possible to facilitate insertion into the nasal cavity, to send a sufficient amount of air into the respiratory tract through the nasal cavity when inserted into the nasal cavity, and to prevent falling out of the nasal cavity as much as possible. can be used, and a cosmetic effect can be obtained.

The enlarged diameter portion 34 is provided at the end on the other end side and has an enlarged outer diameter. A thin portion 341 is formed in the enlarged diameter portion 34 . The enlarged-diameter portion 34 is inclined to face slightly outward and to face downward when the nasal-cavity-insertion tool 1 is inserted into the nasal cavity.

The protruding portion 35 has a tongue shape, protrudes outward from the enlarged diameter portion 34 below the enlarged diameter portion 34, and curves upward.

The guide part 36 has a plate shape, and protrudes into the hollow part 31 from the inner wall 31a forming the hollow part 31 at one end thereof and extends upward. It should be noted that the guide portion 36 is not limited to a plate-like shape, and may have any shape such as a groove.

The communication hole 37 is a through hole that penetrates the main body portion 3 in the thickness direction, and communicates the hollow portion 31 with the outside. The communication hole 37 extends along the extending direction of the hollow portion 31 . The communication hole 37 is formed in the outer side wall of the body portion 3 . Here, the outer side walls are side walls of the left insertion tool 1L and the right insertion tool 1R that do not face each other.

The pressing portion 4 is integrally connected to the body portion 3 at one end and the other end in the extension direction, and the center portion in the extension direction is connected to the body portion 3. There is a gap between The pressing portion 4 has a convex shape in which the center in the extending direction protrudes upward.

<Operation of nasal cavity insertion device>
The operation of the nasal cavity-insertion tool 1 according to the embodiment of the present invention will be described in detail below.

When inserting the nasal cavity-insertion tool 1 into the nasal cavity, the body portion 3 is first inserted into the nasal cavity. At this time, the nasal cavity-insertion tool 1 is inserted into the nasal cavity while the nasal cavity is dilated by the pressing portion 4 abutting against the inner wall of the nasal cavity and pressing the inner wall of the nasal cavity.

By further inserting the nasal cavity-insertion tool 1 into the nasal cavity, the enlarged diameter portion 34 is inserted into the nasal cavity. At this time, the stress is concentrated on the thin portion 341 provided in the enlarged diameter portion 34, and the thin portion 341 is elastically deformed to a greater extent, so that the enlarged diameter portion 34 can be easily inserted into the nasal cavity regardless of the shape of the nasal cavity. can be done.

Then, in a state in which the diameter-enlarged portion 34 is inserted into the nasal cavity, the enlarged-diameter portion 34 engages with the nasal valve at the entrance of the nasal cavity inside the nasal cavity, thereby reliably preventing the nasal cavity-insertion tool 1 from falling out of the nasal cavity. be able to.

After the nasal cavity-insertion tool 1 is completely inserted into the nasal cavity, the nasal bridge is pushed upward by the pressing portion 4, and the levator nasalis superior labialis muscle is also pushed upward. As a result, the nasal cavity can be widened and the entrance to the nasal cavity can be widened, so that a large amount of inhaled air can be taken into the nasal cavity. In addition, since the zygomaticus major muscle extending from the orbit to the orbicularis oris muscle is pushed upward by pushing the levator nasolabialis superior upward with the pressing part 4, the depth of the groove of the nasolabial fold can be made shallow. beauty effect can be obtained. Further, by pressing the inner wall of the nasal cavity with the pressing portion 4, it is possible to prevent the nasal cavity-insertion tool 1 from coming off from the nasal cavity.

In addition, since the body part 3 is pressed downward by the reaction force of the pressing part 4 against the pressing force that presses the nasal bridge upward, the body part 3 can be applied to the depressor depressor septum septum, which ends in the mucous membrane of the lower part of the nasal cavity. Load can be applied evenly.

The nasal cavity is not straight from the entrance to the back due to the anatomical position of the skull. Therefore, when the main body is straightened, when the main body is inserted into a non-straight nasal cavity, the main body tends to fall off and resistance to the flow of intake air is generated. On the other hand, when the nasal cavity-insertion tool 1 is inserted into the nasal cavity, the enlarged diameter portion 34 is inclined slightly outward and downward, so that the nasal cavity-insertion tool 1 conforms to the shape of the nasal cavity. be able to. As a result, it is possible to prevent the nasal cavity-insertion tool 3 from falling out of the nasal cavity, and to reduce the resistance to the intake air flowing through the hollow portion 31, thereby increasing the amount of intake air.

Further, by integrally connecting the enlarged diameter portion 34 and the pressing portion 4, both the enlarged diameter portion 34 and the pressing portion 4 can be mutually reinforced, and deformation of the enlarged diameter portion 34 and the pressing portion 4 can be prevented. can be prevented.

In addition, when the pressing part 4 presses the inner wall of the nasal cavity upward, the reaction force received from the inner wall is transmitted to the protruding part 35, and the protruding part 35 presses the depressor muscle of the nasal septum, thereby expanding the entrance of the nasal cavity. can be done.

Further, by providing a communication hole 37 that communicates between the hollow portion 31 and the outside, the air in the communication hole 37 is sucked into the hollow portion 31 by the flow of air in the hollow portion 31, and the inside of the nasal cavity and the communication hole 37 become hollow. Since the pressure is more negative than that of the portion 31 , body fluid secreted from the mucous membrane of the nose easily evaporates into the hollow portion 31 through the communication hole 17 . Then, the body fluid evaporated in the hollow part 31 rides on the air flow in the hollow part 31 and reaches the inner part of the nasal cavity or the mucosal tissue of the pharynx. As a result, the inner part of the nasal cavity or the pharyngeal mucosal tissue can be kept moist, and the function of the inner part of the nasal cavity or the pharyngeal mucosal tissue can be protected.

Furthermore, by pressing the depressor nasal septum muscle with the expansion part 38, it is possible to apply a load to the depressor nasal septum muscle and prevent the nasal cavity inserting device 1 from falling out of the nasal cavity.

<Flow of air into the body from the nasal cavity into which the nasal insertion device is inserted>
The flow of air into the body from the nasal cavity into which the nasal cavity-insertion tool 1 according to the embodiment of the present invention is inserted will be described in detail below.

The hollow portion 31 of the nasal cavity-insertion instrument 1 extends upward from the other end, and the guide portion 37 extends upward toward the one end, thereby The air sucked into the hollow portion 31 through the second opening 33 of the nasal cavity-insertion instrument 1 is guided upward by the hollow portion 31 and the guide portion 37, released from the first opening 32, and taken into the body. be As a result, the air released from the first opening 32 is guided to the upper nasal meatus or the middle nasal meatus.

Here, the nasal cavity is divided into the superior nasal meatus, the middle nasal meatus, and the inferior nasal meatus in order from above by the nasal turbinates protruding from the left and right side walls. When the paranasal sinuses located deep in the upper and middle nasal passages encounter fast-flowing inspiration, the fast-flowing flow of inspiration stimulates the concentration of nitric oxide NO in the maxillary meatus. Nitric oxide, NO, has a bactericidal effect and relaxes smooth muscle to dilate blood vessels.

Therefore, by providing the guide portion 37 that guides the air inhaled into the hollow portion 31 to the upper nasal meatus and the middle nasal meatus, the concentration of nitric oxide NO can be increased, and nitric oxide NO relaxes smooth muscles. It is possible to prevent myocardial infarction, etc., and to obtain a bactericidal action against viruses or bacteria.

As described above, according to the present embodiment, the hollow portion 31 extends from one end to the other end, and the hollow portion 31 is opened to the outside at the one end. a cylindrical body portion 3 having an opening portion 32 and a second opening portion 33 that opens the hollow portion 31 to the outside at the end portion on the other end side; By having the pressing part 4 extending from the nasal cavity to the other end side, it can be easily inserted into the nasal cavity, and when it is inserted into the nasal cavity, a sufficient amount of air can be sent into the respiratory tract through the nasal cavity. In addition, it is possible to prevent falling out of the nasal cavity as much as possible, and it is possible to obtain a cosmetic effect.

The present invention is not limited to the above-described embodiments in terms of the types, arrangements, numbers, etc., of the members, and may be replaced with those having equivalent functions and effects without departing from the gist of the invention. Of course, it can be changed as appropriate.

Specifically, although the bulging portion 38 is circular, it is not limited to this, and an L-shaped bulging portion may be provided in the left insertion tool 1L and an inverted L-shaped bulging portion may be provided in the right insertion tool 1R.
