Description

Technical Field

[0001] The invention relates to a training device, and in particular to a breathing training device. Background Art

[0002] Breathing training is an important means to improve lung function, enhance respiratory muscle strength, and relieve breathing difficulties. It is especially suitable for groups such as chronic obstructive pulmonary disease (COPD), postoperative rehabilitation, long-term bedridden patients, asthma or COVID-19 survivors.

[0003] Existing breathing training devices adjust breathing resistance to suit the training needs of different patients. However, the resistance adjustment range is narrow, the accuracy is low, and the feedback lags when adjusting the resistance. Users cannot intuitively and promptly determine whether the resistance has changed, which brings many inconveniences.

[0004] In response to the above problems, we provide a breathing training device. Summary of the Invention

[0040] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0041] An embodiment of the present application provides a breathing training device.

[0042] Example 1, as Figure 1-7 shown.

[0043] A breathing training device comprises a main tube 1, which is a hollow tubular structure with both ends open.

[0044] A breathing training device includes a mouthpiece assembly 2 installed at the front end of a main pipe 1. During training, the user bites the mouthpiece assembly 2 in the mouth to prevent it from falling off during training and causing training interruption.

[0045] The bite component 2 includes a bite tube 21, a bite support 22, a buffer pad 23, and a sealing ring 24. The bite tube 21 is detachably installed at the front end of the main tube 1. The inner cavity of the bite tube 21 communicates with the main tube 1. A sealing ring 24 is installed on the outer side of the connection between the bite tube 21 and the main tube 1. Bite supports 22 are respectively arranged on the upper and lower sides at the front end of the bite tube 21, and a buffer pad 23 is arranged at the rear side of the bite support 22. During use, the user's upper and lower teeth respectively bite on the buffer pad 23, and the bite support 22 is located inside the upper and lower teeth to limit the bite component 2 and prevent the bite component 2 from being disengaged during exhalation.

[0046] A fixing convex rib 221 is formed by the upward protrusion in the middle of the bite support 22, which can better fix the bite component 2. The two side surfaces of the bite support 22 located on both sides of the fixing convex rib 221 are concave arc surfaces. One end of the buffer pad 23 is connected to the top of the fixing convex rib 221, and one end is connected to the bottom side of the bite support 22, and the middle part of the buffer pad 23 is in a suspended state. The design of the buffer pad 23 can, on the one hand, increase the comfort of the user's bite, and on the other hand, can adapt to the mouth shapes of different users, having universality.

[0047] At the same time, the detachable connection between the bite tube 21 and the main tube 1 facilitates the user to disinfect it in time after use, avoiding the growth of bacteria and affecting the health of the user.

[0048] A breathing training device includes a sealing component 3, which is installed outside the bite component 2 and buckles on the outside of the user's mouth to seal the user's mouth, making the resistance of the breathing training more accurate and avoiding the change in the perception of the training resistance caused by the non-closure of the user's mouth.

[0049] The closed component 3 includes a closed frame 31, a closed ring 32, and a closed member 33. The closed frame 31 is sleeved in the middle of the bite component 2. A closed ring 32 is provided on the front side of the closed frame 31. A number of closed members 33 are installed between the inner side of the closed ring 32 and the closed frame 31. The sealing ring 24 is pressed against the outside of the patient's mouth through the closed members 33 for sealing. The closed member 33 includes a top plate 331 and a closed spring 332. A number of top plates 331 are arranged at equal intervals on the inner side of the sealing ring 24. A closed spring 332 is installed between the top plate 331 and the sealing frame. Through the closed spring 332, the top plate 331 drives the sealing ring 24 and presses it against the outside of the user's mouth. The shape of the closed ring 32 is oval, which is more suitable for the shape of the user's mouth. At the same time, the closed ring 32 is an arc structure, with an overall inner arc shape, concave forward in the middle and convex backward on both sides, which can be more suitable for the outside shape of the user's mouth and can better seal the user's mouth space.

[0050] A blocking component 4 is provided below the bite component 2. This can prevent saliva from entering the subsequent structure during exhalation, which may breed bacteria over time.

[0051] The blocking component 4 includes a blocking plate 41, a return pipe 42, and a mouth water tank 43. A blocking plate 41 is installed at the rear of the inner cavity of the bite component 2, that is, a blocking plate 41 is installed at the rear of the inner cavity of the bite pipe 21. The blocking plate 41 is installed obliquely with its rear end facing upward. A mouth water tank 43 is installed below the bite component 2. A return pipe 42 is installed on one side of the mouth water tank 43, and the other end of the return pipe 42 is communicated with the inner cavity of the bite component 2. The mouth water tank 43 is communicated with the bottom of the closed frame 31 through a pipeline. The saliva in the closed frame 31 and the bite pipe 21 flows into the mouth water tank 43 along the return pipe 42 or the pipeline. The setting of the blocking plate 41 can prevent saliva from entering the main pipe 1 and polluting the subsequent structure.

[0052] A breathing training device includes a training component 5 installed at the rear end of the main pipe 1. It can adjust the resistance of breathing training.

[0053] The training assembly 5 includes a training tube 51, a valve core 52, a connecting plate 53, a fixed shaft 54, and a dynamic sealing ring 55. The training tube 51 is rotatably connected to the rear end of the main tube 1. A sealing ring is provided at the connection between the training tube 51 and the rear end of the main tube 1 to ensure that the training tube 51 can still be sealed when it rotates. A conical mounting groove 511 is provided inside the training tube 51. The valve core 52 is rotatably connected to the conical mounting groove 511. A spiral airway 512 is provided inside the conical mounting groove 511. The spiral airway 512 has an air inlet 513 and an air outlet 514 on both sides. When in use, the airflow generated by breathing enters the spiral airway 512 from the air inlet 513 and is discharged from the air outlet 514. The side wall of the valve core 52 is provided with a spiral ridge 521 adapted to the spiral airway 512, and a dynamic sealing ring 55 is installed on the inner side of the spiral airway 512. The spiral ridge 521 is squeezed and fitted with the dynamic sealing ring 55. The closed channel surrounded by the spiral airway 512, the spiral ridge 521 and the valve core 52 is the training airway 56. A connecting plate 53 is provided at the rear part of the inner cavity of the main pipe 1, and a fixed shaft 54 is provided in the middle of the connecting plate 53. The other end of the fixed shaft 54 is fixedly connected to the center of the front side of the valve core 52, that is, the valve core 52 is a fixed structure, and the training tube 51 can rotate around the valve core 52. By rotating the training tube 51, the cross-sectional size of the training airway 56 can be changed, thereby changing the resistance of the breathing training.

[0054] To adjust breathing resistance, rotating the training tube 51 changes the distance between the spiral airway 512 and the spiral ridge 521. This changes the cross-section of the training airway 56, resulting in a change in the effective flow area of the training airway 56 and, consequently, the resistance generated during breathing training. Specifically, rotating the training tube 51 clockwise decreases the cross-sectional area of the training airway 56, increasing the breathing resistance. Conversely, rotating the training tube 51 counterclockwise increases the cross-sectional area of the training airway 56, decreasing the breathing resistance. The breathing resistance is inversely proportional to the cross-sectional area of the training airway 56.

[0055] One rotation of the training tube 51 corresponds to the maximum adjustment range of the breathing resistance.

[0056] A toggle component 6 is installed between the main tube 1 and the training component 5. The toggle component 6 provides visual feedback and tactile feedback for the adjustment of the breathing resistance. The dual feedback allows the user to intuitively and promptly understand whether the breathing resistance is adjusted and the specific value of the resistance.

[0057] The toggle assembly 6 includes a connecting ring 61, a limiting ring 62, a moving ball 63, a fixing sleeve 64, a toggle lever 65, and a finger ring 66. A connecting ring 61 is provided on the outer rear end of the main tube 1, and a limiting ring 62 is provided on the rear end of the connecting plate 53. A plurality of fixing grooves 621 adapted to the moving ball 63 are evenly spaced on the rear side surface of the limiting ring 62, and a moving groove 622 is provided between the plurality of fixing grooves 621. A toggle lever 65 is provided on the outer side of the training tube 51, and a fixing sleeve 64 is provided in the middle of the toggle lever 65. A moving ball 63 is placed inside the fixing sleeve 64, and the moving ball 63 can rotate freely inside the fixing sleeve 64. Under normal circumstances, the toggle lever 65 presses the fixing sleeve 64 toward the limiting ring 62 so that the moving ball 63 is located inside the fixing groove 621. The top of the toggle lever 65 is higher than the limiting ring 62. Finger rings 66 are provided on both sides of the top of the toggle lever 65. The finger rings 66 are toggled to drive the training tube 51 to rotate.

[0058] During use, by moving the finger ring 66, the fixed sleeve 64 can be driven to move and the training tube 51 can be rotated through the shift rod 65. When the fixed sleeve 64 moves, the moving ball 63 inside it moves from the fixed groove 621 along the moving groove 622 to the adjacent fixed groove 621. The shift rod 65 has a certain toughness. When the moving ball 63 is located in the moving groove 622, the fixed sleeve 64 is pushed backward a certain distance, driving the upper end of the shift rod 65 to move backward a certain distance. At this time, the shift rod 65 generates a force on the fixed sleeve 64, pressing the moving ball 63 in the moving groove 622 to prevent it from falling out until the moving ball 63 moves to the next fixed groove 621. The depth of the movable groove 622 is less than that of the fixed groove 621, so that the movable ball 63 is subjected to a greater force during movement. When it moves to the next fixed groove 621, the force is reduced, allowing the user to clearly sense through touch that it has moved into the fixed groove 621 and completed a level of breathing resistance adjustment. Each fixed groove 621 corresponds to a level of breathing resistance. There are 18 fixed grooves 621 evenly spaced within 360°, which is sufficient to meet the breathing training needs of each user.

[0059] A plurality of indicator plates 67 are arranged at equal intervals on the outside of the limiting ring 62 . The indicator plates 67 correspond to the fixing grooves 621 one by one, and the indicator plates 67 respectively record the breathing resistance value corresponding to the corresponding fixing groove 621 .

[0060] The toggle assembly 6 also includes a moving dial ring 68 and a track 69. A pair of tracks 69 are provided on the outside of the training tube 51. The moving dial ring 68 is slidably connected to the track 69. Turning the moving dial ring 68 rotates the training tube 51, facilitating the adjustment of the training resistance. The user can rotate the training tube 51 by rotating the moving dial ring 68 or the finger ring 66.

[0061] The rear end of the training component 5 is provided with a breathable cover 7 to prevent debris from entering the interior of the training tube 51 from the exhaust port. The cover can be removed during breathing training.

[0062] When the present invention is used:

[0063] The user holds the device, rotates the training tube to the position of minimum resistance, and then removes the vent cap.

[0064] Open your mouth and bite the biting component so that the sealing component naturally fits on the outside of your mouth.

[0065] First conduct exhalation or inhalation adaptation training to allow users to become familiar with the equipment.

[0066] Then rotate the training tube to adjust the resistance to an appropriate level, and follow the guidance of medical staff to perform corresponding exhalation or inhalation training.

[0067] After use, the bite assembly is disassembled and cleaned.
