Description

Technical Field

[0001] This invention relates to the field of breathing training technology, and more specifically to a breathing training device. Background Technology

[0002] Postoperative patients often experience shallow and weak breathing and respiratory muscle weakness due to surgical trauma, anesthesia, and wound pain. This can easily lead to complications such as atelectasis and lung infection, which seriously affect the postoperative recovery process. Therefore, standardized respiratory rehabilitation training after surgery is an important part of clinical rehabilitation, and corresponding respiratory training equipment has become the core instrument to help patients restore lung function and strengthen respiratory muscle ability.

[0003] Currently, mainstream respiratory training devices on the market have significant shortcomings. Most simple training devices only have a single expiratory training function and cannot simultaneously carry out inspiratory muscle strength training, making it difficult to meet the complete respiratory rehabilitation training needs. The rehabilitation training lacks specificity and comprehensiveness. On the other hand, devices that integrate inspiratory and expiratory dual-mode training functions have a cumbersome overall structure design, a large overall size and space occupation, poor portability, and do not support patients to carry out rehabilitation training anytime and anywhere in various scenarios such as at home or when going out. Their usage scenarios are limited and cannot meet the respiratory rehabilitation training needs of postoperative patients. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a breathing training device. This addresses the issue that most existing simple training devices only have a single expiratory training function and cannot simultaneously conduct inspiratory muscle strength training, thus failing to meet the needs of complete respiratory rehabilitation training. In contrast, devices that integrate both inspiratory and expiratory training modes are too large and lack portability.

[0005] The technical solution adopted in this invention is a breathing training device, comprising: A breathing tube, wherein the upper and lower ends of the breathing tube are the proximal end and the distal end, respectively. A sliding component is linearly slidably assembled inside the breathing tube; A return mechanism is installed between the slider and the breathing tube for resetting the slider. A movable cylinder is fixed to one end of the sliding member, and a connecting groove is provided on the middle side wall of the movable cylinder; An air pump is fixed inside the breathing cylinder. The air pump is located near the proximal end of the breathing cylinder. The air pump is sleeved on the outside of the movable cylinder. The movable cylinder and the air pump are slidably connected in a sealed manner. The upper and lower side walls of the air pump are respectively provided with an inhalation groove and an exhalation groove that are adapted to the connecting groove.

[0006] In a preferred embodiment, the slider has a groove in the middle, and the return mechanism includes multiple sets of return components evenly distributed circumferentially inside the groove. Each return component includes a slider, a ball bearing, and a spring. The slider is slidably installed inside the groove, and one end of the slider has an embedding groove. The ball bearing is rotatably installed inside the embedding groove. The upper and lower inner walls of the breathing tube are provided with return inclined surfaces that converge toward the center. One end of the spring is installed inside the groove, and the other end is fixedly connected to the other end of the slider.

[0007] In a preferred embodiment, the return mechanism further includes a pressure regulating component, which includes a stop block, a regulating post, and a regulating wheel. A regulating groove is formed in the middle of the sliding member, and the regulating groove communicates with the slide groove. One side of the stop block is slidably installed inside the slide groove. The spring is fixed between the slider and the stop block. The regulating post is rotatably installed inside the breathing tube, located inside the regulating groove. The regulating post is used to adjust the position of the stop block within the slide groove. The regulating wheel is rotatably located at the distal end of the breathing tube, and the regulating wheel is fixedly connected to the regulating post.

[0008] In a preferred embodiment, the control column has multiple sets of stepped segments, which are evenly distributed circumferentially and correspond one-to-one with the multiple sets of return components. The stepped segments are adapted to the abutment blocks.

[0009] In a preferred embodiment, the abutment block is fixed with a guide slope at one end near the control column.

[0010] In a preferred embodiment, the regulating wheel has an air exchange passage.

[0011] In a preferred embodiment, the damping rotation of the control wheel is located at the distal end of the breathing tube, and the outer side of the control wheel is provided with anti-slip texture.

[0012] In a preferred embodiment, the air cylinder is provided with a resistance fine-tuning assembly, which includes an exhalation adjustment component, an exhalation adjustment plate, an inhalation adjustment component, and an inhalation adjustment plate. The exhalation adjustment component and the inhalation adjustment component are damped and slidably installed on both sides of the air cylinder body. The inhalation groove and the exhalation groove are both provided with fine-tuning grooves. The exhalation adjustment plate and the inhalation adjustment plate are respectively sealed and slidably installed inside the fine-tuning grooves of the exhalation groove and the inhalation groove. The end of the exhalation adjustment component is fixedly connected to the exhalation adjustment plate, and the end of the inhalation adjustment component is fixedly connected to the inhalation adjustment plate.

[0013] In a preferred embodiment, the fine-tuning groove is formed on the inner wall of the air cylinder, and both the exhalation plate and the inhalation plate are slidably connected to the movable cylinder in a sealed manner.

[0014] In a preferred embodiment, a breathing nozzle is installed at the proximal end of the breathing tube, and a handle is fixed to the side wall of the breathing tube.

[0015] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: When using this breathing training device, the patient inhales or exhales through the mouthpiece. When the patient inhales, the moving cylinder moves proximally with the sliding component, aligning the connecting groove with the inhalation groove. External air enters the cylinder's inner cavity through the inhalation groove and connecting groove, completing the inhalation training. When the user exhales, the moving cylinder moves distally with the sliding component, aligning the connecting groove with the exhalation groove. Gas is expelled through the connecting groove and exhalation groove, completing the exhalation training. The return mechanism provides a resetting force after the sliding component moves, ensuring the device automatically returns to its initial state without external force, guaranteeing the continuity and stability of the training process. This device integrates inhalation and exhalation dual-mode training into a compact coaxial layout, eliminating the need for separate air paths or complex switching mechanisms, effectively reducing the overall size and improving portability.

Detailed Implementation

[0018] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0020] Example:

[0021] like Figure 1-2 As shown, this embodiment provides a breathing training device, including a breathing cylinder 1, a sliding member 11, a return mechanism, a moving cylinder 12, and an air pump 13. The upper and lower ends of the breathing cylinder 1 are the proximal and distal ends, respectively. The sliding member 11 is linearly slidably assembled inside the breathing cylinder 1. The return mechanism is installed between the sliding member 11 and the breathing cylinder 1 for moving and resetting the sliding member 11. The moving cylinder 12 is fixed to one end of the sliding member 11, and a connecting groove 121 is opened on the middle side wall of the moving cylinder 12. The air pump 13 is fixed inside the breathing cylinder 1, located near the proximal end of the breathing cylinder 1, and is sleeved on the outside of the moving cylinder 12. The moving cylinder 12 and the air pump 13 are slidably connected in a sealed manner. The upper and lower side walls of the air pump 13 are respectively provided with an inhalation groove 131 and an exhalation groove 132 adapted to the connecting groove 121. A breathing mouthpiece 41 is installed at the proximal end of the breathing cylinder 1 for the patient to breathe through. A handle 42 is fixed on the side wall of the breathing cylinder 1 for the patient to hold the device.

[0022] In the initial state, the slider 11 and the moving cylinder 12 are in the reset position, and the connecting groove 121 in the middle of the moving cylinder 12 is misaligned and sealed with the inhalation groove 131 and the exhalation groove 132 of the air cylinder 13. The user holds the handle 42 on the side wall of the breathing tube 1 to stabilize the device. The user places the mouthpiece 41 at the proximal end of the breathing tube 1 against the mouth. During inhalation training, the user inhales through the mouthpiece 41. The negative pressure of the airflow causes the moving tube 12 and the sliding member 11 to slide proximally along the inside of the breathing tube 1. The return mechanism stores power until the connecting groove 121 and the inhalation groove 131 are aligned and connected, opening the inhalation path and completing the inhalation resistance training. After inhalation stops, the return mechanism drives the sliding member 11 and the moving tube 12 to automatically return to their original positions, closing the inhalation path. During exhalation training, the user exhales through the mouthpiece 41. The airflow pushes the moving tube 12 and the sliding member 11 to slide distally, aligning the connecting groove 121 and the exhalation groove 132 and opening the exhalation path, completing the exhalation resistance training. After exhalation, the return mechanism drives the sliding member 11 and the moving tube 12 to reset. Breathing training can be repeated in a cycle. All components of this breathing training device are housed inside the breathing cylinder 1. The overall structure is a single cylinder, which is compact and occupies little space, making it easy for patients to hold and carry.

[0023] In one implementation, such as Figure 2 , 3 As shown in Figure 7, a groove 211 is provided in the middle of the sliding member 11. The return mechanism includes multiple sets of return components evenly distributed on the inner side of the groove 211. The return components include a slider 21, a ball 22 and a spring 23. The slider 21 is slidably installed inside the groove 211. One end of the slider 21 is provided with an embedding groove 212. The ball 22 is slidably installed inside the embedding groove 212. The upper and lower inner walls of the breathing tube 1 are provided with return inclined surfaces 221 that converge toward the center. One end of the spring 23 is installed inside the groove 211, and the other end is fixedly connected to the other end of the slider 21. The sliding member 11 can be fixed with a sliding cylinder to realize the function of the sliding groove 211. The excess part of the sliding member 11 can be hollowed out to reduce the weight of the sliding member 11. The gas flows through the gap between the sliding member 11 and the inner wall of the breathing tube 1. If the selected ball bearing 22 is too small, resulting in the gap between the sliding member 11 and the inner wall of the breathing tube 1 being too small, then an appropriate circumferentially evenly distributed groove can be opened on the sliding member 11 to ensure air conduction.

[0024] When the slider 11 slides along the direction of the moving cylinder 12 and the air cylinder 13, the slider 21 moves synchronously with the slider 11. At this time, the ball 22 relies on the elasticity of the spring 23 to abut against the return slope 221 on the inner wall of the breathing cylinder 1. The return slope 221 applies radial extrusion force to the ball 22, and the ball 22 transmits the force to the slider 21. The slider 21 slides inward along the slide groove 211 and compresses the spring 23. When the slider 11 tends to return to the middle of the breathing cylinder 1, the spring 23 releases its elasticity and pushes the slider 21 to move outward. The ball 22 rolls along the return slope 221. With the help of the slope guidance of the return slope 221, the slider 11 completes the return.

[0025] Based on the above implementation methods, such as Figure 2 , 3 As shown in Figure 7, the return mechanism also includes a pressure regulating component, which includes a stop block 24, a regulating post 25, and a regulating wheel 26. A regulating groove 241 is provided in the middle of the sliding member 11, and the regulating groove 241 communicates with the slide groove 211. One side of the stop block 24 is slidably installed inside the slide groove 211. A spring 23 is fixed between the slider 21 and the stop block 24. The regulating post 25 is rotatably installed inside the breathing tube 1, located inside the regulating groove 241. The regulating post 25 is used to adjust the position of the stop block 24 within the slide groove 211. The regulating wheel 26 is rotatably located at the far end of the breathing tube 1, and is fixedly connected to the regulating post 25. The regulating wheel 26 has a ventilation passage 261. The regulating wheel 26 is damped and rotatably located at the far end of the breathing tube 1, and has anti-slip textures on its outer side. The stop block 24 and the regulating post 25 are slidably connected vertically.

[0026] When the adjusting wheel 26 is rotated to adjust the pressure of the spring 23, the adjusting wheel 26 drives the adjusting column 25 to rotate synchronously. The adjusting column 25 pushes the abutment block 24 to slide along the slide groove 211. The abutment block 24 changes the initial compression of the spring 23, thereby adjusting the return resistance of the return mechanism. The damped rotation of the adjusting wheel 26 can maintain the adjusted position of the abutment block 24. The anti-slip texture on the outer side of the adjusting wheel 26 facilitates the rotation by hand. The ventilation passage 261 enables airflow. When the sliding member 11 moves along the direction of the air cylinder 13, the slider 21 compresses the spring 23, and the elastic force of the spring 23 is limited and supported by the abutment block 24.

[0027] The control column 25 has multiple sets of stepped sections 251, which are evenly distributed around the circumference and correspond one-to-one with multiple sets of return components. The stepped sections 251 are adapted to the abutment block 24.

[0028] Rotating the control wheel 26 drives the control column 25 to rotate. The positions of the abutment blocks 24 corresponding to the evenly distributed stepped segments 251 on the circumference of the control column 25 change. The stepped segments 251 of different heights push the abutment blocks 24 to move along the slide groove 211, changing the initial position of the abutment blocks 24. This adjusts the pre-compression degree of the spring 23, realizing the graded adjustment of the return resistance. After the control column 25 rotates to the position, the stepped segments 251 maintain the limiting support of the abutment blocks 24.

[0029] A guide slope 242 is fixed at one end of the abutment block 24 near the control column 25.

[0030] The side of the stepped section 251 is adapted to the guide slope 242 of the abutment block 24, which facilitates the smooth switching of the position of the abutment block 24 relative to the control column 25, thereby changing the pre-compression of the spring 23 and completing the graded adjustment of the return resistance.

[0031] In one implementation, such as Figure 4-6 As shown, the air pump 13 is equipped with a resistance fine-tuning assembly, which includes an exhalation adjustment component 31, an exhalation adjustment plate 311, an inhalation adjustment component 32, and an inhalation adjustment plate 321. The exhalation adjustment component 31 and the inhalation adjustment component 32 are damped and slidably installed on both sides of the air pump 1 body. Both the inhalation groove 131 and the exhalation groove 132 are provided with fine-tuning grooves 33. The exhalation adjustment plate 311 and the inhalation adjustment plate 321 are respectively sealed and slidably installed inside the fine-tuning grooves 33 of the exhalation groove 132 and the inhalation groove 131. The end of the exhalation adjustment component 31 is fixedly connected to the exhalation adjustment plate 311, and the end of the inhalation adjustment component 32 is fixedly connected to the inhalation adjustment plate 321.

[0032] The exhalation adjustment component 31 or the inhalation adjustment component 32 is slidably adjusted. The exhalation adjustment component 31 drives the exhalation adjustment plate 311 to slide in a sealed manner within the fine adjustment groove 33 of the exhalation groove 132, changing the distance between the exhalation groove 132 and the connecting groove 121. The inhalation adjustment component 32 drives the inhalation adjustment plate 321 to slide in a sealed manner within the fine adjustment groove 33 of the inhalation groove 131, changing the distance between the inhalation groove 131 and the connecting groove 121. The change in the resistance of the spring 23 is adjusted by the return slope 221, thereby achieving the adjustment of breathing resistance.

[0033] The fine-tuning groove 33 is opened on the inner wall of the air cylinder 13, and the exhalation plate 311 and the inhalation plate 321 are both sealed and slidably connected to the moving cylinder 12.

[0034] The sliding resistance of the exhalation adjustment component 31 is greater than the sealing sliding resistance between the exhalation adjustment plate 311 and the moving cylinder 12. When the moving cylinder 12 moves, it will not cause the exhalation adjustment plate 311 to be displaced, ensuring that the exhalation adjustment plate 311 and the inhalation adjustment plate 321 will not be moved during the breathing training process.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
