Description

[Technical field]

[0001] The present invention relates to a device for improving sleep disordered breathing, and more particularly to a device for outward traction of a user's tongue. [Background technology]

[0002] Obstructive sleep apnea is a condition where the respiratory tract is blocked by the tongue and soft palate, especially when the patient sleeps lying down, making it difficult to breathe smoothly. The direct cause of the above condition is that when the patient sleeps, the tongue falls backwards due to gravity and the relaxation of the body's tissues, blocking the channel between the oral cavity and the airway, and the fallen tongue presses the patient's soft palate, blocking the channel between the nasal cavity and the airway. Obviously, sleep-disordered breathing causes the patient to have difficulty breathing, which can lead to snoring and even put the patient's life at risk.

[0003] In conventional treatments, there are methods to hold the patient's tongue in a position where it does not collapse by clamping it with pliers or sucking it with negative pressure. In other words, this is a method to prevent the patient's tongue from collapsing by using an external mechanical device. The advantage of such mechanical methods is that they do not burden the patient with the side effects of drugs or the injury caused by surgery. Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional mechanical therapy, the tongue of the patient is sucked out of the oral cavity by pliers or negative pressure during use, and the front end of the tongue is held outside the oral cavity to ensure that the tongue does not fall into the oral cavity. This method pulls the tongue to a large extent, which is likely to make the user feel uncomfortable. In addition, the conventional mechanical therapy often completely fixes the user's tongue in a position where it does not fall, so that the tongue cannot move properly when the user uses the device, the tongue is easily fatigued, and the user cannot use the tongue to help swallow saliva. Too much saliva can also affect the user's breathing.

[0005] Therefore, the present inventors believed that the above-mentioned drawbacks could be improved, and as a result of extensive research, they came to propose the present invention, which effectively improves the above-mentioned problems through rational design.

[0006] The present invention has been made to solve the above problems of the prior art. That is, an object of the present invention is to provide a device that retracts the tongue from inside to outside the oral cavity and allows the user to move the tongue appropriately.

[0057] By providing the stopper portion, the device prevents the user's tongue from dropping, while at the same time not pulling the user's tongue out of the user's lips excessively, so that the user does not feel uncomfortable due to excessive pulling of the user's tongue. In addition, the drive mechanism prevents the user's tongue from dropping, while at the same time allowing the user to move the tongue moderately, for example, by moving the tongue backward to assist in swallowing saliva and prevent saliva from accumulating. After the user has finished moving his or her tongue, the device automatically returns the user's tongue to a position where it does not drop by the drive mechanism.

[0058] The device for improving sleep-disordered breathing according to the present invention comprises a base adapted to be applied to the head of a user and fixed to the head of the user, the base having a channel; a suction member, the suction member extending through the channel to enter the oral cavity of the user and having a hollow flow path which is relatively displaced within the channel, the flow path being connected to a tongue fixing portion, the tongue fixing portion being cup-shaped to be attached to the tongue of the user, a storage space communicating with the flow path being formed, the tongue being stored so as to surround the tongue of the user, the suction member further having a stopper portion located outside the oral cavity, the suction member being used to limit the amount of forward displacement of the tongue fixing portion; an arrangement of the tongue fixing portion which, in use, uses negative pressure to suck the front end of the tongue and goes around the tongue of the user to form a seal, the negative pressure acting only on the tongue, the tongue fixing portion being arranged to face an elastic force adjacent to the base, the elastic force being weaker than the suction force between the suction member and the tongue of the user and weaker than the pulling force when the user moves the tongue; and a negative pressure source communicating with the flow path and providing negative pressure to the tongue of the user with which the tongue fixing portion comes into contact.

[0059] The stopper portion is provided outside the user's oral cavity, simplifying the structure of the device in the user's oral cavity, reducing the volume in the user's oral cavity, reducing the foreign body sensation experienced by the user, and improving the user's comfort. The driving mechanism prevents the user's tongue from collapsing while allowing the user to move the tongue appropriately, for example, by moving the tongue backward to assist in swallowing saliva and prevent saliva from accumulating. After the user has finished moving their tongue, the device automatically returns the user's tongue to a position where it does not collapse by the driving mechanism.

[0060] The tongue fixing portion is arranged to move freely in the oral cavity following the tongue of the user during use, and to drive the tongue of the user to move forward when the tongue is relaxed until it is stopped by the stopper portion. An elastic member provides elasticity to move the tongue fixing portion forward and close to the base. [Brief description of the drawings]

[0062] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited to the following examples, and can be modified as desired without departing from the gist of the present invention.

[0063] Next, a device for improving sleep-disordered breathing according to a first embodiment of the present invention will be described with reference to Figs. 1 to 6. The device for improving sleep-disordered breathing includes a base 10 for fixing to a user's head, a suction member 20 for sucking the user's tongue T, a drive mechanism simultaneously joined to the base 10 and the suction member 20, two adjustment members 40 capable of adjusting the elasticity of the drive mechanism, and a negative pressure source 50 for providing negative pressure to the suction member 20 to suck the user's tongue T. The two adjustment members 40 are a first adjustment member 40a and a second adjustment member 40b, respectively, and are both installed outside the user's oral cavity, the first adjustment member 40a being connected to the base 10, and the second adjustment member 40b being connected to the suction member 20. In this embodiment, the suction member 20 is a tampulator, and the drive mechanism is an elastic member 30 that is a spring. For the convenience of the following explanation, the user's head is taken as the directional reference system, the direction in which the user's face faces is taken as the forward direction, the direction in which the top of the user's head faces is taken as the upward direction, and the direction in which the user's left ear faces is taken as the leftward direction.

[0064] As shown in Figure 3, the base 10 has a tubular portion 11, an outer extension portion 12 connected to the rear of the tubular portion 11, and a channel 13 that penetrates the tubular portion 11 and the outer extension portion 12 along the front-to-rear direction, and the tubular portion 11 is formed so as to protrude forward from the outer extension portion 12.

[0065] As shown in FIG. 2 and FIG. 5, when the device is used, the base 10 needs to be fixed relatively to the user's head. In this embodiment, the outer extension part 12 has a main body 120 extending from the tube part 11 in the left-right direction, and is used to directly contact the face part other than the lips L of the user, preventing the entire base 10 from moving backward and maintaining the front-back position of the base 10. In order to prevent the outer extension part 12 from blocking the user's mouth, the main body 120 of the outer extension part 12 has a plurality of perforations 121, which penetrate the outer and inner surfaces of the outer extension part 12, allowing some users who have difficulty breathing through their nose to breathe through their mouths. The inner surface of the outer extension part 12 faces the surface of the user's face, and the outer surface of the outer extension part 12 faces away from the surface of the user's face. In order to increase the contact area between the outer extension 12 and the user's face, the outer extension 12 has a certain degree of curvature and elasticity, and adheres to the contours of the user's face, dispersing the pressure applied by the outer extension 12 to the user's face. In addition, in order to further improve the fixing effect between the base 10 and the user's head, a fixing element 14 is connected to both left and right ends of the outer extension 12. In this embodiment, the fixing element 14 is a small belt, and the fixing element 14 and the outer extension 12 wrap the user's head and tighten the base 10 in front of the user's mouth. The fixing element 14 further pulls both left and right ends of the outer extension 12, and further adheres to the contours of the user's face. In another embodiment, the fixing element 14 in the form of a small belt is hung on the user's ear. In a few other embodiments, the installation of the outer extension 12 and the fixing element 14 is not essential.

[0066] As shown in FIGS. 3 and 4, the outer surface of the cylindrical portion 11 has a male thread for fitting with the first adjustment member 40a.

[0067] 1, 5 and 6, the entire suction member 20 moves back and forth with respect to the base 10, and the suction member 20 includes a flow path 21 and a tongue fixing portion 22 connected to the flow path 21. The flow path 21 penetrates the channel 13 and extends to enter the user's oral cavity, transmitting the negative pressure generated by the negative pressure source 50 to the user's oral cavity and acting only on the user's tongue T. The flow path 21 is relatively displaced within the channel 13.

[0068] As shown in Figs. 3 to 6, the suction member 20 is provided with at least one stopper portion, and in this embodiment, the outer surface of the flow path 21 has the stopper portion, which is defined as a first stopper portion 211. The first stopper portion 211 is combined with the first adjustment member 40a to limit the amount of displacement of the tongue fixing portion 22 outward (i.e., forward). The tongue fixing portion 22 expands in all directions relative to the flow path 21, and the stopper portion is also provided at the front end of the tongue fixing portion 22, defined as a second stopper portion 220, and is used to limit the amount of displacement of the tongue fixing portion 22 outward (i.e., forward). Specifically, the second stopper portion 220 is located on both the upper and lower sides of the connection portion between the tongue fixing portion 22 and the flow path 21, and engages with the inside of the upper teeth D or lower teeth D of the user as the tongue fixing portion 22 moves, thereby limiting the amount of displacement of the tongue fixing portion 22 outward (i.e., forward). When the device is operated, one of the first stopper portion 211 and the second stopper portion 220 is selected to limit the amount of outward (i.e., forward) displacement of the tongue fixing portion 22. Of course, the first stopper portion 211 and the second stopper portion 220 may be installed simultaneously on the suction member 20, or one of them may be selected and installed without the other.

[0069] As shown in Fig. 1, Fig. 4 and Fig. 5, in this embodiment, the tongue fixing part 22 is made of a soft material that is gentle to the human body, such as silica gel, and has a cup shape so as to be attached to the user's tongue T, and has an accommodation space 221 that is open toward the rear, and accommodates the front end of the user's tongue T from the front end of the user's tongue T when the device is used. In order to place the user's lingual frenulum, the tongue fixing part 22 has two notches 222 facing forward at its rear end, and the two notches 222 are positioned so as to correspond to both the upper and lower sides of the tongue fixing part 22. That is, one of the notches 222 is located below the accommodation space 221, and the other notch 222 is located above the accommodation space 221, and by installing them symmetrically in this way, it is not necessary to distinguish between the upper and lower directions of the tongue fixing part 22 when the user actually uses it. The tongue fixing part 22 faces the inner surface of the user's tongue T, that is, an air inlet 223 is provided to define the inner surface of the receiving space 221, and the receiving space 221 communicates with the flow path 21 through the air inlet 223. Therefore, when the device is used, negative pressure is finally transmitted to the receiving space 221 and acts on the user's tongue T received in the receiving space 221, sucking the user's tongue T to be fixed to the tongue fixing part 22. The tongue fixing part 22 is attached to surround the cross-sectional contour of the user's tongue T and forms a seal, where the cross-sectional contour refers to the four edges of the cross-section of the user's tongue T in the left-right direction, and the negative pressure is transmitted only to the receiving space 221 and does not diffuse to the entire oral cavity. In addition, since the receiving space 221 receives only the user's tongue T, the negative pressure acts only on the user's tongue T and does not act on other parts of the user. In other embodiments, the shape of the tongue fixing portion 22 is not limited to a cup or pocket shape covering the user's tongue T, but may be, for example, a plate-like structure that is attached to the upper surface of the user's tongue T, and has a plurality of air intake ports 223 opened on its underside.

[0070] 4 to 6, in this embodiment, the tongue fixing part 22 includes an inner layer 224 close to the user's tongue T, and an outer layer 225 farther from the user's tongue T than the inner layer 224, and the inner layer 224 and the outer layer 225 are integrally injection molded. In another embodiment, the inner layer 224 and the outer layer 225 are molded separately and then combined, and the material of the inner layer 224 is selected to be softer than the material of the outer layer 225, thereby improving the comfort of the tongue fixing part 22. Alternatively, the thickness of the inner layer 224 is made thinner than the thickness of the outer layer 225, thereby making the inner layer 224 softer than the outer layer 225. A plurality of micro-channels 226 are distributed in the tongue fixing part 22, and the micro-channels 226 are located in the inner layer 224 and between the inner layer 224 and the outer layer 225, and penetrate the inner and outer surfaces of the inner layer 224 and communicate with the flow path 21 and the accommodating space 221. The openings of the micro-channels 226 on the inner surface of the tongue fixing part 22 are distributed on all four sides of the air intake 223, and the hole diameter is smaller than the hole diameter of the air intake 223. This design distributes the negative pressure acting on the user's tongue T, and prevents the negative pressure from concentrating on a narrow area of ​​the user's tongue T, causing the user discomfort.

[0071] As shown in Figs. 4 to 6, the tongue fixing part 22 is provided with a protective pad 23 on the inner surface facing the user's tongue T for use by a user whose tongue T is sensitive to touch. The protective pad 23 is made of a soft material such as foam or silica gel, and has a plurality of fine through holes 231. There is no step between the inner surface of the tongue fixing part 22 and the inner surface of the protective pad 23, and the two form a continuous curved surface Q, and the curved surface Q is attached to the contour of the user's tongue T. When using the device, the protective pad 23 is first placed in the accommodation space 221, so that another user can replace the protective pad 23 and make it usable, and after the user's tongue T enters the accommodation space 221, the protective pad 23 stretches to conform to the shape of the user's tongue T. The inner surface of the tongue fixing portion 22 and the inner surface of the protective pad 23 form a smooth curved surface without any steps, and the curved surface adheres to the contour of the user's tongue T, covering the front end of the tongue T and separating the user's tongue T from the air intake port 223 and the microchannel 226. The negative pressure passes through the through hole 231 of the protective pad 23, further weakening the strong negative pressure applied to the user's tongue T, thereby increasing the comfort of the user. A gap communicating with the flow path 21 is formed between the outside of the protective pad 23 and the inside of the tongue fixing part 22, and in this embodiment, the outer surface of the protective pad 23 has a plurality of convex points 232 protruding toward the inner surface of the tongue fixing part 22, and the convex points 232 abut against the inner surface of the tongue fixing part 22, and the gap communicating with the intake port 223 is formed between the outer surface of the protective pad 23 and the inner surface of the tongue fixing part 22 and between the plurality of convex points 232, and negative pressure passes through the through hole 231 of the protective pad 23. Of course, in other embodiments not shown, the protective pad 23 is designed to be fixed to the inner surface of the tongue fixing part 22, and the convex points 232 are provided on the inner surface of the tongue fixing part 22, but this is not limited thereto.

[0072] When negative pressure acts on the front end of the user's tongue T and the protection pad 23 is not in use, the user's tongue T adheres to the inner surface of the tongue fixing portion 22, and the front end of the tongue T seals the air inlet 223 and the microchannel 226. When the protection pad 23 is used, the user's tongue T adheres to the inner surface of the protection pad 23, and the front end of the user's tongue T seals the through hole 231 of the protection pad 23. In other embodiments, the cross-sectional area of the caliber of the flow path 21 at a location close to the user's tongue T is provided to be reduced, that is, by reducing the vicinity of the air inlet 223, the user's tongue T does not enter the caliber of the flow path 21 due to the suction force and feel uncomfortable. The reduced flow path 21 branches to form a plurality of parallel thin tubes, or forms a flat shape similar to a "one" shape in cross-section.

[0073] As shown in FIGS. 3 and 4, the suction member 20 includes a connector 24 located at its front end. The connector 24 is located outside the base 10 and one end thereof is connected to be fixed to the flow path 21. The connector 24 has a tubular structure. In this embodiment, the connector 24 and the flow path 21 are formed separately, and one end of the connector 24 is fixed to the end of the flow path 21 and is fitted so as to interfere. The connector 24 has a male screw for fitting the second adjusting member 40b on the outer surface at the middle position, and no threads are provided at both ends. In other embodiments (not shown), the connector 24 is formed to be integrally connected to the flow path 21, but is not limited thereto.

[0074] 4 to 6, the first adjustment member 40a has a cylindrical outer shape and includes a baffle 411, a receiving chamber 412 located behind the baffle 411 and penetrating toward the rear, and a receiving cavity 413 located in front of the baffle 411 and penetrating toward the front. A female thread is provided on the inner surface of the receiving chamber 412, and the tube portion 11 is screwed into the female thread of the receiving chamber 412 by a male thread. The first adjustment member 40a moves back and forth relative to the base 10 along the thread by the user only rotating the first adjustment member 40a. The receiving cavity 413 accommodates the elastic member 30 and accommodates the second adjustment member 40b when the suction member 20 is displaced relative to the base 10. The baffle 411 is provided with a through hole 414 penetrating from front to back, and the through hole 414 communicates with the receiving chamber 412 toward the rear and with the receiving cavity 413 toward the front. The flow path 21 penetrates the through hole 414 of the baffle 411 and enters the receiving cavity 413, but since the baffle 411 is located in front of the first stopper portion 211 and limits its position, the length by which the flow path 21 enters the receiving cavity 413 and the amount of outward (i.e., forward) displacement of the tongue fixing portion 22 connected to the flow path 21 are both limited. That is, the user controls the maximum amount of outward displacement of the tongue fixing portion 22 by moving the first adjustment member 40a back and forth. Specifically, by moving the first adjustment member 40a forward, the baffle 411 is moved forward, increasing the movable space of the first stopper portion 211, and further increasing the maximum outward displacement of the tongue fixing portion 22, or conversely, decreasing the maximum outward displacement of the tongue fixing portion 22. In addition, since the baffle 411 is located in front of the tube portion 11, a limited position is formed by locking, and the depth to which the tube portion 11 and the receiving chamber 412 fit is limited. Alternatively, the stroke of adjusting the first adjustment member 40a backward is limited.

[0075] 4 to 6, the second adjustment member 40b has a first hole 421 and a second hole 422 connected to the rear end of the first hole 421, and the size of the second hole 422 is larger than the size of the first hole 421. The first hole 421 is internally provided with a female thread, which is fitted with the male thread on the outer surface of the connector 24 to form a screw connection. By only rotating the second adjustment member 40b, the second adjustment member 40b moves forward and backward relative to the connector 24 along the thread, and the second hole 422 is used to accommodate the elastic member 30. In this embodiment, the overall size of the second adjustment member 40b is smaller than the size of the receiving cavity 413, and when the first adjustment member 40a and the second adjustment member 40b are displaced relative to each other, the second adjustment member 40b is accommodated in the receiving cavity 413 and moves relative to each other. In other embodiments not shown, the size of the second hole 422 may be made larger than the overall size of the first adjustment member 40a, and when the first adjustment member 40a and the second adjustment member 40b are displaced relative to each other, the first adjustment member 40a may be accommodated within the second hole 422, but is not limited to this.

[0076] 3 to 6, in this embodiment, the elastic member 30 is a compression spring, the elastic member 30 is fitted on the part of the flow passage 21 protruding forward from the base 10, and is accommodated in the receiving cavity 413 and the second hole 422, one end of the elastic member 30 directly abuts on the front end surface of the baffle 411 facing rearward, and the other end directly abuts on the hole wall of the second hole 422 of the second adjustment member 40b facing forward. Of course, in other embodiments, other joining methods may be adopted, and the elastic member 30 may provide elasticity to the first adjustment member 40a and the second adjustment member 40b, for example, the elastic member 30 may be fixed to the first adjustment member 40a and the second adjustment member 40b by screws. When the device is used, the elastic member 30 is compressed by the first adjustment member 40a and the second adjustment member 40b to provide elasticity in opposite directions. That is, the elastic member 30 provides a rearward elastic force to the first adjustment member 40a and transmits it to the base 10, the elastic member 30 provides a forward elastic force to the second adjustment member 40b and transmits it to the suction member 20 via the connector 24, the suction member 20 moves forward relative to the base 10, and the tongue T of the user fixed to the tongue fixing part 22 moves forward in conjunction with the tongue fixing part 22, and the front end of the tongue T is kept away from the soft palate and throat of the user by the elastic force, so that the tongue T of the user does not fall down and induce sleep breathing disorder. During the use of the device, the second stopper part 220 is engaged with the teeth D of the user, or the first stopper part 211 is engaged with the baffle 411, so that the tongue fixing part 22 and the tongue T of the user are not pulled out of the lips L of the user.

[0077] Apparently, the device is used when the user is asleep or about to fall asleep and the user's tongue T is relaxed, that is, the target of the device is the user's relaxed tongue T, and the elastic member 30 is installed to provide sufficient elasticity to pull the relaxed tongue T and not to prevent the user from overcoming the elasticity and moving the tongue T. Here, the user moving the tongue T refers to the user moving the muscles to move the tongue T, and does not include the user's relaxed tongue dropping. That is, when the user uses the device, the elasticity is smaller than the suction force between the suction member 20 and the user's tongue T and smaller than the pulling force when the user moves the muscles of the tongue T, and the tongue fixing part 22 moves freely in the oral cavity following the movement of the muscles of the tongue T. When the muscles of the tongue T are relaxed, the tongue fixing part 22 is interlocked to move the user's tongue T forward until it is stopped by the first stopper part 211. In reality, saliva is constantly secreted in the oral cavity of a normal user, and so the user consciously or unconsciously moves the tongue T backward when swallowing saliva. Therefore, when the device is used, it does not affect the user's ability to consciously or unconsciously swallow saliva, and reduces the amount of saliva that accumulates to a certain extent.

[0078] Some users find the elastic force of the second stopper portion 220 abutting against the teeth D or the elastic force acting on the tongue T too strong and uncomfortable. As shown in Figs. 4 to 6, these users can change the compression amount of the elastic member 30 compressed by both of the first adjustment member 40a and the second adjustment member 40b by rotating and changing the position of at least one of them, thereby changing the elasticity provided by the elastic member 30. In this embodiment, the thread pitch of the first adjustment member 40a is larger than the thread pitch of the second adjustment member 40b, that is, when rotated once in the same manner, the displacement amount of the first adjustment member 40a in the front-rear direction is larger than the displacement amount of the second adjustment member 40b in the front-rear direction, so as to provide users with different adjustment accuracy.

[0079] In another embodiment, the first adjustment member 40a and the second adjustment member 40b are not essential, and only one adjustment member may be provided. For example, in an embodiment, only the first adjustment member 40a is provided, and one end of the elastic member 30 close to the user's oral cavity is joined to the first adjustment member 40a, and one end away from the user's oral cavity is joined to the connector 24. Of course, only the second adjustment member 40b may be provided, and one end of the elastic member 30 close to the user's oral cavity is joined to the base 10, and one end away from the user's oral cavity is joined to the second adjustment member 40b. In another embodiment, the elastic member 30 is not limited to a compression spring, and a tension spring, an elastic rubber gasket, or the like may be used as the elastic member 30 under the premise of providing elasticity for pulling the user's tongue T outward.

[0080] As shown in Figures 5 and 6, the device further includes an occlusion part 60, which is located outside the tongue fixing part 22 and extends left and right along the arrangement direction of the teeth D, and the hardness of the occlusion part 60 is higher than that of the tongue fixing part 22. When used, the occlusion part 60 is installed between the upper teeth D and the lower teeth D of the user, and when the user bites the occlusion part 60, the tongue fixing part 22 is not directly bitten by the user and the tongue T is not injured. There are various implementation methods for the occlusion part 60, for example, the occlusion part 60 is fitted to the flow path 21, and the suction member 20 is moved back and forth relative to the occlusion part 60. Alternatively, the occlusion part 60 is formed to protrude from the base 10 toward the inside of the user's mouth. Alternatively, the bite portion 60 and the tongue fixing portion 22 are integrally molded to be connected, and the bite portion 60 is formed to extend from the outer surfaces on both the left and right sides of the suction member 20, however, the bite portion 60 and the tongue fixing portion 22 are formed from two different types of materials.

[0081] 1 to 3, in order to help a user or a caregiver grasp the therapeutic effect of the device, the device further includes a breath sensor 70 disposed above the first adjustment member 40a, which measures and records several physiological parameters related to breathing, such as breathing frequency, snoring volume, etc. Based on the records of these parameters, the user or a caregiver can determine whether the settings, such as the strength of the negative pressure previously used or the elasticity provided by the elastic member 30, are achieving the desired therapeutic effect, and can make adjustments accordingly.

[0082] 1, the suction member 20 and the negative pressure source 50 are connected by a flexible connecting pipe 80. In some embodiments, the connecting pipe 80 has an expandable portion 81 adjacent to the flow path 21, and the length of the connecting pipe 80 can be temporarily extended due to a user changing his / her sleeping position or the like, thereby preventing the connecting pipe 80 from tightening and applying excessive force to the user's tongue T. The expandable portion 81 may be a corrugated tube, a soft tube with good extensibility, or a coil around which the connecting pipe 80 is wound.

[0083] As shown in FIG. 1, the connecting pipe 80 further includes a check valve 82 which is used to ensure that airflow flows in one direction from the tongue support portion 22 to the negative pressure source 50, and ensures that negative pressure is transmitted in one direction from the negative pressure source 50 to the tongue support portion 22.

[0084] As shown in Figures 1 and 7, the negative pressure source 50 includes a known electric vacuum pump 51 for extracting air and creating a negative pressure. The connecting pipe 80 extends into the negative pressure source 50 and is connected to the vacuum pump 51, directly connecting the suction member 20 to the vacuum pump 51 and directly transmitting the negative pressure created by the vacuum pump 51 to the flow passage 21 and the tongue fixing part 22. In another embodiment, the negative pressure is generated by a positive pressure pump. In this embodiment, the positive pressure pump provides an uninterrupted and continuous airflow to another airway, the flow passage 21 communicates with the airway through a check valve to bypass the airway, the check valve allows gas to flow only from the flow passage 21 into the airway, the uninterrupted and continuous airflow creates a low pressure in the airway, and the air in the flow passage 21 passes through the check valve and flows into the airway, creating a negative pressure in the flow passage 21 and the tongue fixing part 22.

[0085] As shown in FIG. 1, there are many components connected between the negative pressure source 50 and the suction member 20, and each component objectively has manufacturing tolerances or wears out with use, and there is a certain deviation in the compatibility between the user's tongue and the tongue fixing part 22 and the mutual installation between each component, so that the airtightness of the device is likely to be lower than the experimental measurement value in actual use. In order to maintain the magnitude of the negative pressure at a predetermined level, the device further includes an air pressure sensor S, which may be selected from a conventional small-volume air pressure sensor available on the market. In this embodiment, the air pressure sensor S is installed inside the negative pressure source 50, and as shown in FIG. 7 and FIG. 8, the connecting pipe 80 includes a main tube communicating with the vacuum pump 51 and the suction member 20, and a branch tube 84 communicating with the main tube and the air pressure sensor S. The air pressure sensor S detects the air pressure therein and transmits the detected air pressure data to a control unit (not shown), and the control unit adjusts the operating power of the vacuum pump 51 according to the level of the air pressure. If the air pressure is lower than a certain predetermined value, the operating power of the vacuum pump 51 is increased, and if the air pressure is higher than another predetermined value, the operating power of the vacuum pump 51 is decreased. In another embodiment, the air pressure sensor S may be installed so as to communicate with the flow path 21.

[0086] 7 and 8, in order to prevent the air pressure sensor S from being affected by liquid and water vapor (which refers to tiny water droplets floating in the air, not gaseous water molecules) in the connecting pipe 80 or the flow path 21, in this embodiment, a waterproof part 85 is installed in the branch tube 84, and the size of the waterproof part 85 is significantly larger than the inner diameter of the branch tube 84 to ensure that it completely covers the cross section, and is embedded in the tube wall by an insert molding process to ensure the watertightness of the connection point between the waterproof part 85 and the branch tube 84. The branch tube 84 including the waterproof part 85 is molded independently of the body of the connecting pipe 80 and is installed in the main tube of the connecting pipe 80. In another embodiment, the waterproof part 85 may be bonded in the branch tube 84 using an adhesive.

[0087] In this embodiment, Goretex (R) (registered trademark) film is used as the waterproof part 85. (R) The Goretex® material is waterproof and breathable, and is widely used in the field of outdoor equipment. (R) The air permeability of the waterproof part 85 made of the (registered trademark) film allows air to be transmitted between the waterproof part 85 and the air pressure sensor S. As a result, the air pressure sensor S directly detects the change in air pressure in the connecting pipe 80, and is not affected by the liquid and water vapor in the connecting pipe 80.

[0088] In another embodiment, the material (e.g., polyethylene) selected for the waterproof part 85 is waterproof and prevents the penetration of gas molecules, and the waterproof part 85 is in the form of a film, so its thickness is reduced and it is elastic, and it deforms in response to the air pressure difference on both sides of the waterproof part 85. That is, the waterproof part 85 has the properties of being waterproof, airtight, thin, lightweight, and elastically deformable, and the waterproof part 85 isolates the gases on both sides from circulating with each other. When the air pressure on both sides of the waterproof part 85 is the same, the waterproof part 85 is held flat without deformation. When the air pressure inside the connecting pipe 80 is lower than the air pressure between the waterproof part 85 and the air pressure sensor S, the waterproof part 85 protrudes toward the connecting pipe 80 and deforms, and the space between the waterproof part 85 and the air pressure sensor S becomes wider, so that the air pressure decreases, and the air pressure sensor S indirectly detects the decrease in air pressure in the connecting pipe 80. Conversely, if the air pressure in the connecting pipe 80 is higher than the air pressure between the waterproof part 85 and the air pressure sensor S, the waterproof part 85 protrudes toward the air pressure sensor S and deforms, narrowing the space between the waterproof part 85 and the air pressure sensor S and causing the air pressure to rise, which is detected by the air pressure sensor S.

[0089] As shown in FIG. 1, the negative pressure source 50 further has a protective case 52 covering its outer surface, and the protective case 52 is made of materials such as leather or silica gel and is used to cushion the negative pressure source 50 from any shocks that it may receive during use.

[0090] As shown in FIG. 1, in this embodiment, the device further includes a liquid collection mechanism C communicating with the connecting pipe 80, the liquid collection mechanism C including a liquid collection bag for collecting saliva sucked into the connecting pipe 80 by the suction member 20.

[0091] 1, in this embodiment, the device further includes two fixing mechanisms 90, one of which is a clip and is covered on the connecting pipe 80. In practical use, to prevent the long connecting pipe 80 from excessive swinging or winding, a user can fix it to a solid stationary object with the clip.

[0092] As shown in FIG. 1, the other fixing mechanism 90 is a band that is connected to the protective case 52 or is clamped between the protective case 52 and the outer surface of the negative pressure source 50 and is wrapped around the user's body to fasten the negative pressure source 50 to the user's body.

[0093] 9 is a schematic diagram showing a device for improving sleep-disordered breathing according to a second embodiment of the present invention. The main difference from the first embodiment is that when a part of the base 10 is used for the device, it needs to be inserted into the user's mouth, and therefore the method of fixing the base 10 to the user's head is different, and the method of preventing the connection pipe 80 from becoming tight is also different.

[0094] As shown in Figs. 9 and 10, the base 10 also has a tube portion 11, and its structure and function are the same as the tube portion 11 of the first embodiment. The base 10 further has a flat portion 15 connected to the rear end of the tube portion 11 and an inner extension portion 16 connected to the rear end of the flat portion 15, and the channel 13 penetrates the tube portion 11, the flat portion 15, and the inner extension portion 16 along the front-rear direction. Since the flat portion 15 is installed so as to be positioned between the upper lip L and the lower lip L of the user when the device is in use, the size of the flat portion 15 in the vertical direction is smaller than the size in the horizontal direction, and it fits the shape of the user's lips L. The channel 13 and the flow path 21 penetrating the flat portion 15 are smaller in the vertical direction than the size in the horizontal direction to fit the shape of the flat portion 15. Since the inner extension portion 16 is installed so as to be positioned between the user's teeth D and lips L when the device is in use, the entire base 10 is fixed to the user's head by engaging with the gap between the user's teeth D and lips L. In order to fit the oral cavity structure between the user's teeth D and lips L, the inner extension portion 16 curves and extends along the outside of the user's teeth D, roughly forming a U-shape, and the inner extension portion 16 also extends vertically relative to the flat portion 15 to fit between the user's gums and lips L, and both the upper and lower edges of the inner extension portion 16 are provided with recesses 161 for placing the user's labial frenulum. In other embodiments, the provision of the inner extension portion 16 is not essential.

[0095] 9, in this embodiment, a separable mechanism 83 is used to replace the telescopic part 81 of the first embodiment. The separable mechanism 83 has a tubular structure and connects the disconnected connecting pipe 80, and both ends of the separable mechanism 83 are fitted inside the connecting pipe 80. When the connecting pipe 80 is tightened due to a change in the user's sleeping position and the tension of the connecting pipe 80 is stronger than the holding force between the connecting pipe 80 and the separable mechanism 83, the connection between the connecting pipe 80 and the separable mechanism 83 is released, thereby preventing the tightened connecting pipe 80 from excessively pulling the user's tongue T.

[0096] 11 is a schematic diagram showing a device for improving sleep-disordered breathing according to a third embodiment of the present invention. When the base 10 is used in the device, it is necessary to insert the base 10 into the oral cavity of the user. The base 10 has an upper dental sheath 17 and a lower dental sheath 18 located behind the flat portion 15, and the channel 13 is located between the upper dental sheath 17 and the lower dental sheath 18. The upper dental sheath 17 and the lower dental sheath 18 have receiving slots 170 and 180, respectively, for receiving the user's teeth D correspondingly, and receive the upper teeth D and the lower teeth D of the user correspondingly. The base 10 is engaged with the user's teeth D by the upper dental sheath 17 and the lower dental sheath 18, and the entire base 10 is fixed to the user's head. In this embodiment, in order to enhance the comfort of the user, the inner surfaces of the receiving slots 170 and 180 contact the user's teeth D and are covered with a soft material, such as silica gel, which is softer than the material of the upper dental sheath 17 and the lower dental sheath 18. Since the user's teeth D are surrounded by the dental sheaths, when the device is used, the second stopper portion 220 abuts at least one of the upper dental sheath 17 and the lower dental sheath 18, but does not directly contact the user's teeth D. In this embodiment, the second stopper portion 220 abuts the upper dental sheath 17 and the lower dental sheath 18.

[0097] 11, in this embodiment, the upper dental sheath 17 and the lower dental sheath 18 are roughly aligned vertically and are provided for use by a general user. In another embodiment, in order to accommodate a user with severe symptoms of sleep breathing disorder, the lower dental sheath 18 is installed so as to protrude forward relative to the upper dental sheath 17, and the lower dental sheath 18 pulls the user's lower jaw forward, displacing the user's tongue T attached to the lower jaw forward and away from the user's throat.

[0098] As shown in Fig. 11, in this embodiment, the device does not have any of the adjustment members 40, and the base 10 has an extension 19 located outside the lips L of the user, the extension 19 is disposed around the outside of the flow passage 21, and an annular cavity 191 is formed between the base 10 and the extension 19, the annular cavity 191 penetrates the base 10 toward the front, and the extension 19 has a stop surface 192 at the rear end of the annular cavity 191. The structure of the connector 24 in this embodiment is similar to that of the connector 24 in the first embodiment, and is integrally formed with the second adjustment member 40b, and the connector 24 also has a tubular structure, and has a protrusion 241 protruding along the radial direction at its middle portion, and the outer edge of the protrusion 241 extends toward the rear to partially cover the extension 19 and the elastic member 30. The elastic member 30 is accommodated in the annular cavity 191 and the protrusion 241, and is disposed outside the flow passage 21. The rear end of the elastic member 30 abuts against the stop surface 192 toward the rear, and the front end of the elastic member 30 abuts directly against the rear end of the protrusion 241 .

[0099] 12 to 15 are schematic diagrams showing a device for improving sleep-disordered breathing according to a fourth embodiment of the present invention. The device includes a base 10 for fixing to a user's head, a suction member 20 for pulling the user's tongue T forward, an elastic member 30, a first adjustment member 40a for adjusting the amount of forward displacement of the user's tongue T, and a negative pressure source (not shown).

[0100] 13 and 14, the general structure of the suction member 20 is similar to and the same as that of the first embodiment, and therefore the description thereof will not be repeated here. As shown in Fig. 14, in this embodiment, the outer diameter of the flow passage 21 is obviously smaller than the diameter of the channel 13, the channel 13 is not filled in the flow passage 21, and there is a certain gap between the flow passage 21 and the base 10 to provide the suction member 20 with a certain movable space in the vertical or horizontal direction.

[0101] As shown in FIG. 13, the flow path 21 includes a front stage 21a and a rear stage 21b located behind the front stage 21a. The front stage 21a has a vertical size larger than its horizontal size, and is an upright strip, which enhances the flexibility of the flow path 21 in the vertical direction. The rear stage 21b has a vertical size smaller than its horizontal size, and is a horizontal strip, which enhances the flexibility of the flow path 21 in the vertical direction. When the front stage 21a curves and deforms left and right, the flow path 21 also follows and curves and deforms left and right. When the rear stage 21b curves and deforms up and down, the flow path 21 also follows and curves and deforms up and down. Therefore, the flow path 21 has a function of simultaneously deforming in the horizontal direction and the vertical direction due to the difference in shape between the front stage 21a and the rear stage 21b. On the other hand, when the flow path 21 curves left and right, the horizontal deformation is concentrated in the front stage 21a. When the flow path 21 is curved up and down, the vertical deformation is concentrated on the rear section 21b. The tongue fixing part 22 is connected to the rear end of the flow path 21, and the tongue fixing part 22 is connected to the rear section 21b, so that the tongue fixing part 22 can move in other directions perpendicular to the front-rear direction, such as up, down, left, right, etc., due to the bending deformation of the flow path 21, thereby ensuring the flexibility of the tongue fixing part 22 and the user's tongue T. Of course, in other embodiments, the front section 21a is installed so that the size in the up-down direction is smaller than the size in the left-right direction, and has a horizontal strip shape, and the rear section 21b is installed so that the size in the up-down direction is larger than the size in the left-right direction, and has an upright strip shape, and such an installation also realizes the tongue fixing part 22 to move in other directions perpendicular to the front-rear direction.

[0102] 14 and 15, in this embodiment, the front end of the flow passage 21 is cylindrical in front of the front section 21a, accommodates the connector 24, and the flow passage 21 and the connector 24 are screwed together. The front end of the connector 24 is extended beyond the flow passage 21 and protrudes radially from the portion accommodated in the flow passage 21 to form the protrusion 241, and the front end of the protrusion 241 is a stopper portion, which is defined as a third stopper portion 242 and is used to engage with the first adjustment member 40a. The connector 24 accommodates and fixes the connecting pipe 80, and has a step portion 243 inside the rear end of the connector 24, which protrudes from the pipe wall of the connector 24 to limit the amount of coupling with the connecting pipe 80 and prevent the connecting pipe 80 from being excessively installed and penetrating the connector 24. At the front end of the connector 24, an adhesive accommodating portion 244 is provided in the protrusion 241, and the diameter of the adhesive accommodating portion 244 is larger than the outer diameter of the connecting pipe 80, and a certain amount of adhesive is accommodated therein, so that the connector 24 and the connecting pipe 80 are further fixed to each other. In another embodiment, the outer diameter of the connecting pipe 80 is larger than the diameter of the connector 24, and the two are fixed to each other so as to interfere with each other by interference joint, and at this time, the adhesive accommodating portion 244 has a function of guiding the connecting pipe 80 to be connected to the connector 24.

[0103] 14 and 15, a portion where the connector 24 screws into the flow passage 21 is defined as a coupling portion 245. In this embodiment, the coupling portion 245 is housed within the flow passage 21, and in other embodiments, the coupling portion 245 can also house the flow passage 21. The coupling portion 245 is fitted onto the outer periphery of the connection pipe 80. The radial outside of the protrusion 241 is defined as a sliding portion 246, and the surface of the sliding portion 246 is smoothed to reduce the frictional force when it comes into contact with the inner wall of the tube portion 11.

[0104] As shown in Fig. 13 and Fig. 14, the protective pad 23 has a fixing protrusion 233 protruding forward, the fixing protrusion 233 penetrates the intake port 223 and enters the rear section 21b, and its shape is adapted to the shape of the rear section 21b. Two interference parts 234 are provided on the upper and lower surfaces of the fixing protrusion 233, respectively, to increase the fastening force between the fixing protrusion 233 and the rear section 21b. In this embodiment, the interference part 234 has a convex shape extending forward and backward, and may be provided as a protruding dot or other shape. In another embodiment, the protruding interference part 234 may be provided on the inner surface of the pipe wall of the rear section 21b, and the surface of the fixing protrusion 233 may be provided as a groove that fits the interference part 234, to strengthen the fastening between the fixing protrusion 233 and the rear section 21b.

[0105] 12 to 14, in this embodiment, the base 10 is substantially the same as that in the first embodiment, and the difference is that the inner side of the outer extension 12 has two pads 122 added to one side facing the user's face, and the pads 122 are made of a breathable material such as sponge, so as to enhance the comfort of the outer extension 12 when it is applied to the user's face, and to prevent the skin of the user's face from being compressed by the outer extension 12 and becoming stunted. In addition, the front section 21a, the elastic member 30, and the connector 24 are simultaneously housed in the channel 13. Therefore, in this embodiment, the tube portion 11 and the channel 13 are longer than those in the first embodiment.

[0106] 14, the elastic member 30 is covered outside the front stage 21a, its front end abuts the rear of the protrusion 241, and its rear end abuts the stopper 131 in the channel 13. In this embodiment, the stopper 131 and the base 10 are integrally molded, so that in this embodiment, the elastic force of the elastic member 30 acts directly on the base 10 and the suction member 20. In other embodiments, the elastic member 30 is fixed to the base 10 and the suction member 20 by rivets, pins, or adhesives, respectively. In this embodiment, the spring-type elastic member 30 is closer to the inner wall surface of the channel 13 than the flow path 21, so as to avoid interference with the flow path 21 when the elastic member 30 deforms in a non-axial direction.

[0107] 13 and 14, in this embodiment, a protective member 25 is provided so as to be removably installed on the base 10. The protective member 25 includes a ring 251 fitted to the outside of the tubular portion 11, and extends rearward to penetrate the outer expansion portion 12 and is located on both the left and right sides of the rear portion 21b. The thickness of the protective member 25 is greater than that of the rear portion 21b, preventing the user's teeth D from directly biting the flow passage 21 and damaging the flow passage 21.

[0108] As shown in Figs. 12 to 14, in this embodiment, the first adjustment member 40a is in the form of a cylindrical sleeve, fitted on the outside of the tubular portion 11, and connected to the tubular portion 11 by a thread. A user can rotate the first adjustment member 40a to move it along the tubular portion 11. The outer peripheral surface of the first adjustment member 40a is provided with lines extending forward and backward, thereby increasing frictional force. The baffle 411 at the front end of the first adjustment member 40a is provided with a plurality of communication holes 415 surrounding the through hole 414, and both the through hole 414 and the communication holes 415 are connected to the channel 13. The aperture of the through hole 414 gradually expands from the rear to the front, and the connecting pipe 80 passing through the through hole 414 provides a certain degree of movement space. The communication holes 415 are used to exhaust gas or liquid entering the channel 13. The front end of the first adjustment member 40a is the baffle 411 which engages with the third stopper portion 242, and the user can change the front-rear position of the engagement point between the first adjustment member 40a and the third stopper portion 242 by moving the first adjustment member 40a forward and backward, and adjust the front-rear position of the entire suction member 20 and the user's tongue T. Specifically, when the user moves the first adjustment member 40a forward, the compression spring of the elastic member 30 is released and stretched forward, pushing the connector 24 and further pushing and moving the entire suction member 20 forward, and the user's tongue T also moves forward following the suction member 20, and stops when the third stopper portion 242 abuts against the baffle 411 again. Conversely, when the user moves the first adjustment member 40a backward, the amount of displacement of the user's tongue T toward the front can be reduced.

[0109] In this embodiment, the default position of the tongue fixing part 22 during use is located behind the user's teeth D, but for users with severe symptoms, this default position is insufficient to resolve the sagging of the tongue T. For such users, the first adjustment member 40a is moved forward to increase the forward displacement of the tongue T. In general, a good effect is obtained when the front end of the user's tongue T passes the user's teeth D forward. In order to avoid the protective member 25 obstructing the forward movement of the tongue fixing part 22, it is necessary to remove the protective member 25 before adjustment. In addition, such users need to use the bite portion 60 to prevent the user's teeth D from biting the tongue fixing part 22.

[0110] 12 to 14, in this embodiment, two bite portions 60 are provided. The two bite portions 60 are connected to each other via a connection portion 61, which is covered on the outer periphery of the tongue fixing portion 22, and each bite portion 60 has two position limiting ribs 62 on its edge facing the upper and lower sides of the user's teeth D. The two position limiting ribs 62 are installed so as to be positioned on the inside and outside of the user's teeth D during use, and limit the bite portion 60 between the upper and lower teeth D of the user.

[0111] Most of the components of the device, including the adjustment member 40, the base 10, the connector 24, and the flow passage 21, are made of soft materials, and when the threads of the above-mentioned components are also integrally molded with soft materials, the conventional thread shapes such as triangular threads and trapezoidal threads cannot provide sufficient connection strength, and the conventional threads that are combined with each other are easily deformed, slip, and detached. As shown in FIG. 15, in order to solve the above-mentioned problem, the thread between the first adjustment member 40a and the base 10 and the thread between the coupling portion 245 and the flow passage 21 are both specially shaped "back hook" threads ST. The characteristic of such back hook threads ST is that the width of the apex is wider than the width of the valley in the thread axial direction. In this embodiment, the shape of the back hook thread ST is a "dovetail" shape, or an inverted trapezoid shape compared to the conventional trapezoidal thread. In such a dovetail-shaped back hook thread ST, the width of the thread shape gradually increases from the valley to the apex in the thread axial direction, and both the apex of the male thread and the apex of the female thread partially overlap in the radial direction. That is, the apex of the male thread and the apex of the female thread are radially defined relative to each other, preventing the apex from coming off the corresponding valley of the thread. Thus, this arrangement prevents the two threads made of soft material from slipping off. Of course, the shape of the back hook thread ST is not limited to this, and may be, for example, T-shaped.

[0112] The flexible flow passage 21 and the flexible connector 24 are attached to each other by an automated machine (not shown). In this embodiment, the flow passage 21 is fitted to the outside of the connector 24, and the machine positions the flow passage 21 and fixes the flow passage 21 when the flow passage 21 and the connector 24 are attached. As shown in Figs. 13 and 15, the front end of the flow passage 21 has a plurality of bumps 213 protruding in the radial direction on its outer surface, and each bump 213 extends along the front-rear direction and fits the machine. In an embodiment in which the flow passage 21 is fitted inside the connector 24, the bumps 213 are provided on the outer surface of the connector 24.

[0113] FIG. 16 is a schematic diagram showing a device for improving sleep-disordered breathing according to a fifth embodiment of the present invention. The device includes a base 10 for fixing to a user's head, a suction member 20 for sucking the user's tongue T, a drive mechanism that is simultaneously joined to the base 10 and the suction member 20, a first adjustment member 40a that allows adjustment of the distance the user's tongue T moves forward, and a negative pressure source 50 that provides negative pressure to the suction member 20 to suck the user's tongue T. The drive mechanism is a spring elastic member 30. A breath sensor 70 is mounted on the base 10. In this embodiment, the negative pressure source 50, the connection pipe 80, and the fixing mechanism 90 are the same as those in the first embodiment, so reference can be made to the first embodiment and the description thereof will not be repeated.

[0114] 17 and 20, the base 10 has a tubular portion 11, an outer extension portion 12 connected to the rear of the tubular portion 11, and a channel 13 penetrating the tubular portion 11 and the outer extension portion 12 along the front-rear direction, and the tubular portion 11 is formed by protruding forward from the outer extension portion 12. In this embodiment, the main body 120 of the outer extension portion 12 is provided with a plurality of the perforations 121 having a horizontal elongated shape parallel to each other, and the breath sensor 70 is fixed to the outer extension portion 12 by the perforations 121.

[0115] As shown in Figures 17 and 18, in this embodiment, the outer extension 12 is reduced in size as a whole compared to the previous embodiment, and covers only the lips and adjacent four areas of the user. A plurality of pads 122 are fixed to the inside of the outer extension 12 on one side facing the user. The upper edge of the outer extension 12 has a notch 123 formed as a downward recess, which is used to place the user's nose. Two of the pads 122 are located on both the left and right sides of the notch 123 and are used to contact the skin above the user's upper lip. The other pad 122 is located at the lower end of the outer extension 12 and is used to contact the skin below the user's lower lip.

[0116] As shown in Fig. 18 and Fig. 19, each of the pads 122 has a plurality of finger portions 1221 protruding toward the user's face, and the left and right sides of each of the finger portions 1221 are mutually penetrating to form a hollow. The finger portions 1221 are deformed after contacting the user's face due to the hollow space and their own flexibility, and the ends of the finger portions 1221 contract toward the outer extension portion 12 while the upper and lower sides of the finger portions 1221 expand, absorbing the pressure of the outer extension portion 12 against the user's face. The plurality of finger portions 1221 located on the same pad 122 are arranged at intervals, and the left and right widths of each of the finger portions 1221 gradually contract in the direction from the main body portion 120 toward the user's face, and correspondingly, the left and right widths of the intervals between two adjacent finger portions 1221 gradually expand. With this arrangement, the plurality of finger portions 1221 can fully adapt to the curvature of the outer extension portion 12 and the user's face. As shown in Figures 17 and 18, the outer four corners of the outer extension part 12 have four block parts 124, and the block parts 124 protrude from the outer surface of the main body 120 of the outer extension part 12. Each block part 124 includes a crown part 1241 and a stem part 1242, and the stem part 1242 is connected to the outer surface of the main body 120 of the outer extension part 12, and the crown part 1241 protrudes from the stem part 1242. An engagement groove (not shown) is formed between the crown part 1241 and the outer surface of the outer extension part 12, and is used for combining with the fixing element 14. The fixing element 14 is provided with a buckle 141 that engages with the stem part 1242 and rotates around the stem part 1242 as an axis. The crown part 1241 and the buckle 141 are engaged with each other to restrict the fixing element 14 from being detached from the outer extension part 12.

[0117] For most users, the tongue drop position and the maximum position reached by pulling the tongue do not overlap, and there is a gap between the two. Simply removing the tongue from the drop position produces the effect of alleviating symptoms. However, since the comfortable tongue position acceptable to each user is not the same within the aforementioned gap, the device is provided with a first adjustment member 40a that can be adjusted by the user himself.

[0118] As shown in Figures 19 and 20, the tube portion 11 of the base 10 protrudes forward from the outer surface of the outer extension portion 12, and the channel 13 penetrates the tube portion 11 and the outer extension portion 12 in the front-rear direction. In this embodiment, the tube portion 11 has a female screw directly exposed in the channel 13, and the first adjustment member 40a includes a cylindrical rod portion 416, which has a male screw on its outer periphery, which is housed in the tube portion 11 and engages with the female screw of the tube portion 11. An operation cap 417 is attached to the front end of the rod portion 416, and the rod portion 416 and the operation cap 417 are fixed by a screw 418. The outer periphery of the operation cap 417 has a striation protruding along the front-rear direction to increase friction, and the user manually twists the operation cap 417 to rotate the entire first adjustment member 40a. In order to prevent the first adjustment member 40a from being excessively screwed into the tubular portion 11, the diameter of the operating cap 417 is made larger than the inner diameter of the tubular portion 11, and the rear end of the operating cap 417 is engaged with the front end of the tubular portion 11, thereby limiting its position.

[0119] 19 and 20, in this embodiment, the screw 418 penetrates the operation cap 417 and the rod portion 416 at the same time, and the operation cap 417 serves as a transmission mechanism for interlocking to rotate the rod portion 416. A portion of the rod portion 416 corresponding to the screw 418 protrudes radially from other portions, and a positioning block 4161 is formed, which fits into a positioning groove (not shown) of the operation cap 417 and is aligned with the mounting holes of the screw 418 in the rod portion 416 and the operation cap 417. Similar to the fourth embodiment, the through hole 414 and the communication hole 415 are provided at the front end of the first adjustment member 40a, and in this embodiment, the through hole 414 and the communication hole 415 are provided in the operation cap 417.

[0120] 19 and 20, the front end of the flow passage 21, the connector 24, the elastic member 30 and a part of the connecting pipe 80 are accommodated in the first adjustment member 40a, and the connection relationship between the flow passage 21, the connector 24 and the connecting pipe 80 refers to the above-mentioned fourth embodiment. In this embodiment, a hook 419 protruding toward the axis line is provided at the rear end of the rod portion 416, and the elastic member 30 is also a compressed spring, the rear end of which abuts against the hook 419 and the front end of which is fixed to the connector 24, providing elasticity that causes the connector 24 to push the front end of the first adjustment member 40a. 20 and 21, when the user rotates the first adjustment member 40a and moves it forward and backward with respect to the base 10, the rear end of the elastic member 30 abuts against the hook 419, and moves forward and backward directly following the first adjustment member 40a, and the front end of the elastic member 30 moves forward and backward following the first adjustment member 40a by the connector 24, and moves the entire suction member 20 forward and backward, adjusting the front and rear position of the user's tongue. Since both ends of the elastic member 30 simultaneously move the same distance in the same direction following the first adjustment member 40a, the amount of expansion and contraction of the elastic member 30 does not change according to the movement of the first adjustment member 40a, and the elastic force of the elastic member 30 does not change according to the movement of the first adjustment member 40a, and the elastic force is transmitted to the user's tongue by the suction member 20, becoming a pulling force that pulls the user's tongue forward. In this manner, in this embodiment, the user's tongue is subjected to a traction force and is held stably and consistently, and the traction force on the tongue does not relax during the process of adjusting the tongue position, so that the user's tongue is held in a position where it will not collapse.

[0121] 22, the connector 24 is formed by attaching a coupling part 245 and a sliding part 246 which are separately molded to each other. The sliding part 246 is accommodated in the first adjustment member 40a, and the front end of the elastic member 30 is accommodated in the sliding part 246 so as to be fixed thereto. The front end of the sliding part 246 forms the third stopper part 242 and is engaged by the operation cap 417 of the first adjustment member 40a. One end of the coupling part 245 is detachably accommodated in the sliding part 246 and covers the connection pipe 80, and the other end of the coupling part 245 is covered in the flow passage 21 so as to be fixed thereto. In this embodiment, the coupling part 245 and the sliding part 246, and the coupling part 245 and the flow passage 21 are both connected to each other by threads, but the thread between the coupling part 245 and the sliding part 246 is a triangular thread with a large thread pitch, and the thread between the coupling part 245 and the flow passage 21 is a rectangular thread with a small thread pitch, so that the former is easier to install and remove than the latter. Preferably, the size of the opening of the hook 419 of the rod part 416 is equal to or larger than the maximum size of the front end of the flow passage 21 accommodated in the first adjustment member 40a, so that after the coupling part 245 and the sliding part 246 are detached from each other, the sliding part 246 remains in the first adjustment member 40a, and the coupling part 245 and the flow passage 21 exit from the rear end (i.e., the end close to the user) of the first adjustment member 40a. A thread between the connecting part 245 and the sliding part 246 allows a user to replace the suction member 20 except for the sliding part 246, and the user can purchase corresponding consumable materials and perform maintenance of the device by himself. Furthermore, the flow passage 21 and the connecting part 245 have sufficient elasticity and their sizes are slightly larger than the size of the opening of the hook 419, so that the flow passage 21 and the connecting part 245 can deform to pass through the opening of the hook 419. In another embodiment, the sliding part 246 directly abuts on the front end of the elastic member 30, and the sliding part 246 serves as a second adjustment member to adjust the expansion and contraction of the elastic member 30.

[0122] As shown in FIG. 23 and FIG. 24, in this embodiment, the microchannel 226 is formed by perforating the inner surface of the tongue fixing part 22 (i.e., the laser R is incident from the receiving space 221) with the laser R, thereby forming a plurality of closely packed microchannels 226 having the same hole diameter. The plurality of microchannels 226 are arranged in a plurality of rows, and a plurality of microchannels 226 are arranged in each row. The diameter of each microchannel 226 is 0.5 mm, the hole diameter is uniform, the microchannels 226 are extended straight, and the microchannels 226 are arranged at an angle to the flow path 21. In order to prevent the laser R from destroying the suction member 20 due to excessive burning, a guard member P is installed in the flow path 21 to prevent the laser R from penetrating the flow path 21. It should be noted here that the surface of the guard member P needs to be treated so as not to reflect the laser R.

[0123] The remaining undisclosed structure of the fifth embodiment is substantially the same as that of the fourth embodiment, and therefore the description thereof will not be repeated here.

[0124] In each of the above-mentioned embodiments, the elastic member 30 is used as the driving mechanism. In another embodiment, a pneumatic cylinder type is used as the driving mechanism, and the maintained negative pressure not only acts directly on the user's tongue T to fix it to the suction member 20, but also acts on the entire suction member 20, and the entire suction member 20 is continuously pulled forward using the negative pressure, and the user's tongue T is pulled outward to prevent it from falling. In another embodiment, the elasticity of the elastic member 30 is used, or the negative pressure is maintained by a pneumatic cylinder, and in addition to these two types of tongue T pulling means, a magnetic force may also be used to pull the user's tongue T, for example, a solenoid valve may be used.

[0125] 25 is a schematic diagram showing a device for improving sleep-disordered breathing according to a sixth embodiment of the present invention. The driving mechanism is similar to that of the first embodiment, and the elastic force of the elastic member 30 is used to pull the user's tongue T outward, but the mechanism for fixing the user's tongue T is different from that of the above-mentioned embodiment. The base 10 of the above embodiment is similarly configured to include the channel 13, the link rod 21A penetrating the channel 13, the pliers 22A as a tongue fixing part connected to the rear end of the link rod 21A, and the front cover 23A connected to the front end of the link rod 21A, and the elastic member 30 is a compression spring that is fitted around the outside of the link rod 21a, and the rear end of the elastic member 30 abuts against the base 10 and the front end abuts against the front cover 23A. The pliers 22A, the link rod 21A, and the front cover 23A constitute a tampulator 20A, and the front cover 23A receives a forward elastic force of the elastic member 30, and the link rod 21A transmits the elastic force to the pliers 22A, moving the pliers 22A forward relative to the base 10. As a result, the pliers 22A clamps both the upper and lower sides of the user's tongue T in the user's mouth, thereby fixing the tongue T, and finally pulling the user's tongue T outward. In this embodiment, the front end of the holding portion 221A of the pliers 22A has two second stopper portions 220 that mutually engage with the user's teeth D.

[0126] 26 to 29 are schematic diagrams showing a device for improving sleep-disordered breathing according to a seventh embodiment of the present invention. The device includes a base 10, a tampulator 20B movably penetrating the base 10, a first adjustment member 40a connected to the base 10, a second adjustment member 40b connected to the tampulator 20B, and an elastic member 30 installed between the first adjustment member 40a and the second adjustment member 40b. The elastic member 30 is a driving mechanism that provides a forward elastic force to the second adjustment member 40b and links the tampulator 20B to move forward relative to the base 10. The tampulator 20B has a flow path 21 extending forward and backward and a tongue fixing part 22B connected to the flow path 21, the flow path 21 penetrating the channel 13 of the base 10, and the tongue fixing part 22B entering the user's oral cavity during use to fix the user's tongue T.

[0127] As shown in Figs. 27 and 28, the outer surface of the flow path 21 has the first stopper portion 211 that defines the position relative to the first adjustment member 40a in the front-rear direction, and limits the amount of displacement of the tongue fixing portion 22B outward (i.e., forward). The rear end of the flow path 21 has a flexible portion 212, the wall of which is thinner than other portions of the flow path 21. Therefore, the flexible portion 212 is more flexible than other portions of the flow path 21 and allows a certain degree of deformation. The tongue fixing portion 22B has two hollow holding portions 221B, each of which has extensibility and communicates with the flow path 21 via the flexible portion 212. The two holding portions 221B are installed facing each other vertically, and when the device is used, the two holding portions 221B are attached so as to correspond to the upper and lower surfaces of the user's tongue T. The surface of each of the holding parts 221B that is attached to the user's tongue T has a plurality of protruding ribs 222B, and the protruding ribs 222B extend in the left-right direction to increase the frictional force between the holding part 221B and the user's tongue T. The tongue fixing part 22B further has an elastic restraining hood 223B, which simultaneously accommodates the two holding parts 221B and the user's tongue T during use and prevents the holding parts 221B from detaching from the user's tongue T. In this embodiment, an opening 224B for placing the user's lingual frenulum is recessed in the rear edges of both the holding part 221B and the restraining hood 223B.

[0128] As shown in Fig. 28 and Fig. 29, when the device is used, the user's tongue T is inserted into the restraining hood 223B and positioned between the two holding parts 221B. In this embodiment, the holding part 221B is connected to an air supply pump (not shown) via the flow path 21, and the holding part 221B is supplied with air and expands, and applies pressure to the user's tongue T, so that the user's tongue T is sandwiched between the two expanding holding parts 221B. As a result, when the elastic member 30 moves the tampulator 20B forward, the tongue fixing part 22B pulls the user's tongue T forward, preventing the user's tongue T from dropping. In another embodiment, the holding part 221B may be expanded by injecting liquid.

[0129] In the sixth and seventh embodiments, the driving force provided by the driving mechanism 30 is weaker than the traction force that the tumblers 20A and 20B exert on the user's tongue T, and is weaker than the tensile force exerted when the user moves the tongue T.

[0130] The device for improving sleep disordered breathing of the present invention has the following beneficial effects. (1) By providing these stopper portions on the suction member 20 or the tampulators 20A and 20B, the device prevents the user's tongue T from falling, and at the same time, prevents the user's tongue T from being pulled outside the user's lips L, and prevents the user's tongue T from being pulled excessively, causing the user discomfort. (2) The device prevents the user's tongue T from collapsing, while allowing the user to move the tongue T moderately, for example, by moving the tongue T backwards to assist in swallowing saliva and prevent saliva from accumulating. After the user has finished moving the tongue T, the device automatically returns the user's tongue T to a position where it does not collapse by the elasticity of the elastic member 30, or the negative pressure in the pneumatic cylinder, or the mutually attractive magnetic force. (3) In some embodiments, the first adjustment member 40a and the second adjustment member 40b adjust the tensile force received by the tongue T by the user adjusting the elasticity provided by the elastic member 30. (4) In some embodiments, the micro-channels 226 and the protective pad 23 sufficiently distribute the negative pressure suction force on the user's tongue T so as not to cause discomfort to the user. (5) In some embodiments, the outer extension 12 has a plurality of the perforations 121, which prevents the outer extension 12 from sealing against the user's mouth and allows users who have difficulty breathing through their nasal passages, such as patients with nasal congestion, to breathe through their oral cavity. (6) In some embodiments, the bite portion 60 is placed between the user's upper and lower teeth D, and the hardness of the bite portion 60 is made greater than the hardness of the suction member 20, thereby preventing the suction member 20 and the user's tongue T fixed to the suction member 20 from being subjected to excessive bite force, which could result in injury to the tongue T. (7) In some embodiments, when the user rotates the first adjustment member 40a and moves it forward and backward relative to the base 10, the rear end of the elastic member 30 abuts against the hook 419, and moves forward and backward directly following the first adjustment member 40a, the front end of the elastic member 30 moves in conjunction with the rear end, and the connector 24 moves the entire suction member 20 forward and backward following the first adjustment member 40a in conjunction with the first adjustment member 40a, thereby adjusting the front and rear position of the user's tongue. Both ends of the elastic member 30 move in the same direction and the same distance simultaneously following the first adjustment member 40a, the amount of expansion and contraction of the elastic member 30 does not change following the movement of the first adjustment member 40a, and the elastic force of the elastic member 30 does not change following the movement of the first adjustment member 40a, and the elastic force is transmitted to the user's tongue by the suction member 20, and serves as a traction force that pulls the user's tongue forward. As a result, in this embodiment, the traction force received by the user's tongue T is maintained stably and consistently, preventing the traction on the tongue T from relaxing during the process of adjusting the position of the tongue T, and maintaining the user's tongue T in a position where it does not collapse.
