DIAPHRAGM NASAL BREATHING REGULATOR

Abstract

A diaphragm nasal breathing regulator includes a cylinder, a diaphragm, and an engaging unit. The cylinder has a channel, two openings opposite to each other along an axial direction of the cylinder, and a bearing surface allowing the diaphragm to be disposed thereon. The engaging unit engages the diaphragm to the cylinder. The diaphragm is formed with a through hole, and is movable relative to the bearing surface between an inhaling position and an exhaling position. When the diaphragm is in the exhaling position, the diaphragm rests on the bearing surface, and air can flow only through the two openings, the channel, and the through hole. When the diaphragm is in the inhaling position, the diaphragm is away from the bearing surface in the axial direction, and air can flow through the two openings, the channel, the through hole, and a gap between the cylinder and the diaphragm.

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwanese Invention Patent Application No. 112116646, filed on May 4, 2023, the entire disclosure of which is incorporated by reference herein.

FIELD

The disclosure relates to a medical device for assisting breathing, and more particularly to a diaphragm nasal breathing regulator.

BACKGROUND

Referring to FIGS. 1 and 2, a conventional nasal breathing control apparatus 1 disclosed in U.S. Patent Application Publication No. US20210137723A1 is provided. The conventional nasal breathing control apparatus 1 includes two cylinders 11, a bridging portion 12 connected between the cylinders 11, and two floats 13 movably disposed in the cylinders 11, respectively. Each of the cylinders 11 has a chamber 111 and an extending projection 112. The chamber 111 has a first opening 113 that is on one end of the chamber 111, and a plurality of second openings 114 that are on an opposite end of the chamber 111, where a radius of each of the second openings 114 is smaller than that of the first opening 113. The extending projection 112 is disposed inside the chamber 111 and is adjacent to the first opening 113. Each of the floats 13 is disposed in the respective chamber 111 and is disposed between the second openings 114 and the extending projection 112.

The cylinders 11 are adapted to be inserted into two nostrils (not shown) of a user (not shown) with the first openings 113 facing away from the nostrils. As shown in FIG. 1, when the user is inhaling, for each of the cylinders 11, an upward airflow would impel the float 13 disposed in the chamber 111 of the cylinder 11 to move from the first opening 113 toward the second openings 114, and the upward airflow may pass around the float 13 and through the second openings 114. As shown in FIG. 2, when the user is exhaling, a downward airflow would impel the float 13 to move from the second openings 114 toward the first opening 113, and the float 13 would be blocked by the extending projection 112, thereby blocking the first opening 113.

As such, the conventional nasal breathing control apparatus 1 may train the user to inhale through their nostrils and exhale through their mouth. However, since the first opening 113 is blocked by the float 13, the downward airflow is unable to be released from the first opening 113 when the user attempts to exhale through their nostrils, causing discomfort similar to nasal congestion to the user, or even causing the user to have trouble breathing or be choked.

SUMMARY

Therefore, an object of the disclosure is to provide a diaphragm nasal breathing regulator that can alleviate at least one of the drawbacks of the prior art.

According to the disclosure, a diaphragm nasal breathing regulator includes a nasal plug. The nasal plug includes a cylinder, a diaphragm, and an engaging unit.

The cylinder surrounds and defines a channel that extends in an axial direction of the cylinder, that has a first opening and a second opening opposite to each other along the axial direction, and that includes a first channel section adjacent to the first opening and a second channel section adjacent to the second opening, where a radius of the second channel section is smaller than that of the first channel section. The cylinder includes a first inner surface that surrounds and defines the first channel section, a second inner surface that surrounds and defines the second channel section and that has an edge opposite to the second opening, and a bearing surface that is connected to the edge of the second inner surface and that faces the first opening.

The diaphragm is disposed in the first channel section and is formed with a through hole that extends through the diaphragm along the axial direction and that has a radius smaller than that of the second channel section. The diaphragm includes a first surface and a second surface that are opposite to each other along the axial direction and that face the first opening and the second opening respectively, an inner surrounding side that defines the through hole, and an outer surrounding side that is opposite to the inner surrounding side in a radial direction perpendicular to the axial direction.

The engaging unit includes a first engaging part that is formed on the first inner surface, and a second engaging part that is formed on the diaphragm and that movably engages the first engaging part in a manner where the diaphragm is movable relative to the bearing surface between an inhaling position and an exhaling position. When the diaphragm is in the exhaling position, the second surface of the diaphragm rests on the bearing surface, and air can flow only through the first opening, the first channel section, the through hole, the second channel section, and the second opening. When the diaphragm is in the inhaling position, the diaphragm is away from the bearing surface in the axial direction, and air can flow through the second opening, the second channel section, the through hole, the first channel section, a gap between the first inner surface and the outer surrounding side, and the first opening.

Referring to FIGS. 3 to 5, a diaphragm nasal breathing regulator according to a first embodiment of the disclosure includes two nasal plugs 2 and a connection component 6. Each of the nasal plugs 2 includes a cylinder 3, a diaphragm 4 and an engaging unit 5. Since the nasal plugs 2 are the same, only one of the nasal plugs 2 will be explained below.

The cylinder 3 includes an outer surrounding wall 31, an inner surrounding wall 32 that is surrounded by the outer surrounding wall 31 and that is detachably connected to the outer surrounding wall 31, a flange 324 that is connected to the inner surrounding wall 32, and an engaging mechanism 34 that interconnects the outer surrounding wall 31 and the inner surrounding wall 32.

The outer surrounding wall 31 and the inner surrounding wall 32 cooperatively surround and define a channel 33. The channel 33 extends in an axial direction (Z) of the cylinder 3, which is an up-down direction shown in FIG. 3, and has a plurality of first openings 331, and a second opening 332 opposite to the first openings 331 in the axial direction (Z), where the first openings 331 are located at the top of the channel 33 in the axial direction (Z) and the second opening 332 is located at the bottom of the channel 33. The channel 33 further includes a first channel section 333 that is adjacent to the first openings 331, and a second channel section 334 that is adjacent to the second opening 332, where a radius of the second channel section 334 is smaller than that of the first channel section 333.

In the first embodiment, there are five first openings 331, wherein four of the first openings 331 are spaced apart and arranged along a circumferential top edge of the outer surrounding wall 31, and surround the other one of the first openings 331. In some embodiments, the channel 33 may have only one first opening 331.

The outer surrounding wall 31 includes a first inner surface 311 and a first outer surface 312 that are opposite to each other in a radial direction which is perpendicular to the axial direction (Z). The first inner surface 311 includes a first surface portion 313 that is adjacent to the first openings 331 and that surrounds the first channel section 333, a second surface portion 314 that is adjacent to the second opening 332 (i.e., the second surface portion 314 is lower than the first surface portion 313 in the axial direction (Z)), and a shouldering surface portion 315 that is connected to and between the first surface portion 313 and the second surface portion 314. Specifically, the shouldering surface portion 315 is connected between a bottom edge of the first surface portion 313 and a top edge of the second surface portion 314, and faces downward in the axial direction (Z). The second surface portion 314 surrounds and defines a containing space 316, where a radius of the containing space 316 is greater than that of the first channel section 333.

The inner surrounding wall 32 is disposed in the containing space 316, and includes a second inner surface 321, a second outer surface 322, and a bearing surface 323. The second inner surface 321 surrounds the second channel section 334. The second outer surface 322 is opposite to the second inner surface 321 in the radial direction and is surrounded by the second surface portion 314. The flange 324 extends from the second outer surface 322 radially outward in the radial direction, and is adjacent to the second opening 332. Each of the second inner surface 321 and the second outer surface 322 has an edge opposite to the second opening 332 (i.e., a top edge in the axial direction (Z)). The bearing surface 323 has a ring shape having an outer circumference that is connected to the edge of the second outer surface 322 and an inner circumference that is connected to the edge of the second inner surface 321, and the bearing surface 323 faces the first openings 331, where the shouldering surface portion 315 of the first inner surface 311 is laid on the bearing surface 323.

The engaging mechanism 34 includes two bases 341 that are disposed on the second outer surface 322 of the inner surrounding wall 32, and two hooks 342 that extend, from an end of the outer surrounding wall 31 that is adjacent to the second opening 332, toward the second opening 332 (i.e., the hooks 342 extend downwardly from the bottom of the outer surrounding wall 31 in the axial direction (Z)), and that are connected to the bases 341 respectively. Specifically, each of the bases 341 is formed with an inner space, and the hooks 342 are inserted into the inner spaces respectively of the bases 341 such that the hooks 342 removably engage the bases 341.

Referring to FIGS. 3, 6, 7 and 15, the diaphragm 4 is disposed in the first channel section 333, and is formed with a through hole 45 that extends through the diaphragm 4 along the axial direction (Z) and that has a radius smaller than that of the second channel section 334. The diaphragm 4 includes a first surface 41 that faces the first openings 331, a second surface 42 that is opposite to the first surface 41 in the axial direction (Z) and that faces the second opening 332, an inner surrounding side 43 that defines the through hole 45, and an outer surrounding side 44 that is opposite to the inner surrounding side 43 in the radial direction.

The engaging unit 5 includes a first engaging part 51 that is formed on the first surface portion 313 of the first inner surface 311, and a second engaging part 52 that is formed on the diaphragm 4 and that movably engages the first engaging part 51. Specifically, the first engaging part 51 is formed on the first surface portion 313 at a position adjacent to the shouldering surface portion 315.

The first engaging part 51 has a restricting slot 511, a restricting surface 512, and an engaging space 513. The restricting slot 511 extends radially outward from the first surface portion 313 of the first inner surface 311 toward the first outer surface 312, and has a first side (bottom side) adjacent to the bearing surface 323 and a second side (top side) opposite to the first side in the axial direction (Z). The restricting surface 512 defines the second side of the restricting slot 511 and faces the bearing surface 323. The engaging space 513 extends from the restricting surface 512 in the axial direction (Z) away from the bearing surface 323 (i.e., the engaging space 513 extends upwardly from the restricting surface 512) and is in spatial communication with the restricting slot 511. To describe in further detail, the restricting surface 512 extends, from the first inner surface 311, radially outward in an inclined direction toward the second opening 332 (i.e., downwardly and radially outward).

The second engaging part 52 includes an extension part 521 that extends radially outward from the outer surrounding side 44 of the diaphragm 4 in the radial direction, and a bulge 522 that extends from the extension part 521 in the axial direction (Z) away from the bearing surface 323 (i.e., extends upwardly). The extension part 521 is disposed in the restricting slot 511, and the bulge 522 movably engages the engaging space 513.

The connection component 6 is adapted to connect the nasal plugs 2, and includes two rings 61 that respectively surround the nasal plugs 2, and a bridge 62 that is connected between the rings 61 and that has a curved shape.

Further referring to FIG. 8, the bulge 522 movably engages the engaging space 513 in a manner where the diaphragm 4 is movable relative to the bearing surface 323 between an inhaling positon (see FIG. 8) and an exhaling position (see FIG. 7).

When a user (not shown) using the diaphragm nasal breathing regulator is inhaling, air flows from the second opening 332 into the second channel section 334 and impels the diaphragm 4 to move upwardly from the exhaling position to the inhaling position, which is away from the bearing surface 323 in the axial direction (Z). In this embodiment, when the diaphragm 4 is in the inhaling position, the extension part 521 is in contact with the restricting surface 512, and one end of the diaphragm 4 that is adjacent to the first engaging part 51 is closer to the second opening 332, in the axial direction (Z), than another end of the diaphragm 4 that is farther from the first engaging part 51. That is to say, when the diaphragm 4 is in the inhaling position, the diaphragm 4 is inclined relative to the bearing surface 323. In such as case, air can flow through the second opening 332, the second channel section 334, the through hole 45, the first channel section 333, a gap between the first inner surface 311 and the outer surrounding side 44, and the first openings 331.

When the user is exhaling, air flows from the first openings 331 into the first channel section 333 and impels the diaphragm 4 downwardly to the exhaling position. When the diaphragm 4 is in the exhaling position, the first surface 41 of the diaphragm 4 is away from the restriction surface 512 in the axial direction (Z), and the second surface 42 of the diaphragm 4 rests on the bearing surface 323. In such as case, air can flow only through the first openings 331, the first channel section 333, the through hole 45, the second channel section 334, and the second opening 332.

In comparison to the diaphragm 4 in the exhaling position, the diaphragm 4 in the inhaling position allows air to flow further through the gap between the first inner surface 311 of the outer surrounding wall 31 and the outer surrounding side 44 of the diaphragm 4. As such, an amount of airflow through the nasal plug 2 when the diaphragm 4 is in the inhaling position is greater than that of when the diaphragm 4 is in the exhaling position, thus ensuring smooth breathing and improving comfort of the user, and regulating the amount of airflow when the user is exhaling so as to reduce noises caused thereby.

It should be noted that, in the first embodiment, the connection component 6 is used for connecting the nasal plugs 2 to prevent any one of the nasal plugs 2 from being lost, but in some embodiments, the connection component 6 may be omitted. Furthermore, in the first embodiment, the two nasal plugs 2 are used to be respectively inserted into two nostrils of the user, but in some embodiments, only one nasal plug 2 may be used to be inserted into a nostril of the user according to user needs.

Referring to FIGS. 9 to 12, the diaphragm nasal breathing regulator according to a second embodiment of the disclosure is similar to the first embodiment. Differences between the two embodiments will be described in the following.

In the second embodiment, the first engaging part 51′ only has two guiding slots 514 that are formed on the first surface portion 313 of the first inner surface 311, that are opposite to each other in the radial direction, and that extend from the bearing surface 323 toward the first openings 331 in the axial direction (Z) (i.e., extending upward from the bearing surface 323). The second engaging part 52′ includes two of the extension parts 521, and the bulge 522 of the first embodiment is omitted. The extension parts 521 extend radially outward from the outer surrounding side 44 of the diaphragm 4 and movably engage the guiding slots 514 respectively.

In this embodiment, the outer surrounding wall 31′ of the cylinder 3 further includes two air passages 317 that are on the first inner surface 311 of the outer surrounding wall 31′ and that are opposite to each other in the radial direction, where the air passages 317 extend from the bearing surface 323 toward the first openings 331 in the axial direction (Z) (i.e., extend upward from the bearing surface 323).

In the second embodiment, there are two air passages 317, but in some embodiments, there may be only one air passage 317 or more than two air passages 317.

Referring to FIG. 11, when the diaphragm 4 is in the exhaling position, the second surface 42 of the diaphragm 4 rests on the bearing surface 323, and air can flow only through the first openings 331, the first channel section 333, the through hole 45, the second channel section 334, and the second opening 332. Referring to FIG. 13, when the diaphragm 4 is in the inhaling position, the second surface 42 of the diaphragm 4 is away from the bearing surface 323 in the axial direction (Z), and air can flow through the second opening 332, the second channel section 334, the through hole 45, the air passages 317 each between the outer surrounding side 44 and the first inner surface 311, the first channel section 333, and the first openings 331.

In the second embodiment, the diaphragm 4 is movable between the inhaling position (FIG. 13) and the exhaling position (FIG. 11) by the extension parts 521 moving up and down along the guiding slots 514, such that movement of the diaphragm 4 is stable.

Further referring to FIG. 14, the diaphragm nasal breathing regulator according to a third embodiment of the disclosure is similar to the second embodiment. Differences between the two embodiments will be described in the following.

In the third embodiment, the diaphragm 4′ is formed with a plurality of air slots 46 that extend radially inward from the outer surrounding side 44 toward the inner surrounding side 43, and the outer surrounding wall 31′ omits the air passages 317. However, in some embodiments, the outer surrounding wall 31′ may have the air passages 317 while the diaphragm 4′ has the air slots 46. In this embodiment, there are eight air slots 46, but in some embodiments, there may be, but not limited to, only one air slot 46.

When the diaphragm 4′ is in the inhaling position, air can flow through the second opening 332, the second channel section 334, the through hole 45, the air slots 46 each between the outer surrounding side 44 and the first inner surface 311, the first channel section 333, and the first openings 331. As such, the third embodiment provides substantially the same function as the second embodiment.

In summary, the diaphragm 4, 4′ of the disclosure is able to be moved between the inhaling position and the exhaling position. When the diaphragm 4, 4′ is in the exhaling position, the diaphragm 4, 4′ rests on the bearing surface 323. When the diaphragm 4, 4′ is in the inhaling position, the diaphragm 4, 4′ is away from the bearing surface 323 in the axial direction (Z) so that air can flow through the gap between the first inner surface 311 and the outer surrounding side 44, the air passages 317, or the air slots 46. As such, the amount of airflow through the nasal plugs 2 when the diaphragm 4, 4′ is in the inhaling position is greater than that of when the diaphragm 4, 4′ is in the exhaling position, thus ensuring smooth breathing and improving comfort of the user, and regulating the amount of airflow when the user is breathing.
