Description

Technical Field

[0001] This utility model relates to the field of breathing training device technology, specifically to a breathing training device. Background Technology

[0002] In respiratory medicine clinics, diseases such as bronchitis, asthma, pneumonia, pulmonary embolism, pulmonary fibrosis, and lung tumors often lead to a decrease in vital capacity, which directly affects the recovery process. Therefore, vital capacity training is an important part of promoting rehabilitation. Currently, respiratory trainers are commonly used in clinical practice to assist patients in deep breathing exercises to improve vital capacity. This method can help patients strengthen their respiratory muscles and improve lung ventilation function to some extent.

[0003] However, existing breathing trainers have significant shortcomings. Their airflow channels for exhalation and inhalation are the same, meaning that expiratory and inspiratory resistance can only be adjusted simultaneously, not independently. In actual training, different patients have different conditions and lung functions, and the needs of the same patient vary at different stages of rehabilitation, often requiring different resistance levels for exhalation and inhalation. Existing trainers struggle to meet these more precise and targeted breathing training needs, thus limiting the improvement of training effectiveness. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a breathing trainer.

[0005] This utility model discloses a breathing trainer, comprising a main body and an air resistance assembly. The main body has a breathing channel, and the air resistance assembly is disposed within the breathing channel. The air resistance assembly includes an air resistance core, an expiratory coordination component, an inspiratory transmission component, and a reset elastic component. The air resistance core is movably disposed within the breathing channel, and one end of the air resistance core has multiple expiratory through holes. The expiratory coordination component is rotatably connected to the air resistance core, and the expiratory coordination component has expiratory coordination holes corresponding to the expiratory through holes. The inspiratory transmission component is threadedly connected to the air resistance core, and the inspiratory transmission component forms an axial sliding connection with the main body. The reset elastic component is disposed between the inspiratory transmission component and the main body. The expiratory coordination component can be rotated relative to the air resistance core to adjust the expiratory resistance. The air resistance core can be rotated to drive the inspiratory transmission component to move axially, thereby adjusting the compression force of the reset elastic component and thus adjusting the inspiratory resistance.

[0006] According to one embodiment of the present invention, the main body of the device includes an exhalation regulating component and an inhalation regulating component; the exhalation regulating component is rotatably connected to the main body of the device; the inhalation regulating component is rotatably connected to the main body of the device; the exhalation regulating component is used to drive the exhalation regulating component to rotate; the inhalation regulating component is used to drive the air resistance core component to rotate.

[0007] According to one embodiment of the present invention, the exhalation regulating component is connected to the exhalation cooperating component via the exhalation transmission component; rotating the exhalation regulating component can drive the exhalation cooperating component to rotate relative to the air resistance core component.

[0008] According to one embodiment of the present invention, the exhalation fitting is provided with an exhalation closure portion; the exhalation closure portion is used to close the exhalation fitting hole during inhalation.

[0009] According to one embodiment of the present invention, the open end of the air resistance core is sealed to the air intake port of the main body; when the airflow pressure is greater than the compression force of the reset elastic element, the open end of the air resistance core separates from the air intake port.

[0010] According to one embodiment of the present invention, an air intake transmission component is provided with an air intake through hole on its side; the air intake through hole is used to connect the breathing channel and the air intake outlet.

[0011] According to one embodiment of the present invention, the reset elastic element is a spring; one end of the reset elastic element presses against the air intake transmission element; the other end of the reset elastic element presses against the air intake on / off port of the main body.

[0012] According to one embodiment of the present invention, the exhalation through-hole is arranged in a fan-shaped ring and is rotationally symmetrical; the exhalation matching hole is also arranged in a fan-shaped ring and is rotationally symmetrical.

[0013] According to one embodiment of the present invention, an air vent is provided at one end of the breathing channel of the main body of the fuselage; and a breathing inlet and outlet are provided at the other end of the breathing channel of the main body of the fuselage.

[0014] According to one embodiment of the present invention, a mouth mask is provided at the breathing inlet / outlet end; the mouth mask is used to cover the user's mouth.

[0015] Compared with the prior art, the breathing trainer of this utility model has the following advantages: This invention relates to a respiratory trainer, comprising a main body and an air resistance assembly. The air resistance assembly includes an air resistance core, an expiratory coordination component, an inspiratory transmission component, and a reset elastic component, which work together to achieve independent adjustment of expiratory and inspiratory resistance. The expiratory coordination component is rotatably connected to the air resistance core. By rotating it relative to the air resistance core, the correspondence between the expiratory through-hole and the expiratory coordination hole can be changed, thereby precisely adjusting the expiratory resistance to meet the personalized needs of different patients or different stages of rehabilitation for the same patient. Simultaneously, the rotation of the air resistance core can drive the axial movement of the inspiratory transmission component, thereby changing the compression force of the reset elastic component and achieving flexible adjustment of inspiratory resistance, allowing the inspiratory training resistance to be adapted to actual needs. This independent adjustment method overcomes the deficiency of existing respiratory trainers where expiratory and inspiratory resistance can only be adjusted synchronously, making respiratory training more targeted and precise. This helps respiratory patients conduct effective lung capacity training based on their own lung function, improving training effectiveness and promoting recovery. In addition, the connection method of each component is stable and reliable, ensuring the accuracy of resistance adjustment and the stability of equipment use, further guaranteeing the effectiveness and safety of the training process.

[0020] See Figure 1-4 This embodiment provides a breathing trainer that, through a reasonable structural design, can divide the breathing channel into independent expiratory and inspiratory channels, and respectively adjust the expiratory resistance and inspiratory resistance, thereby meeting the precise needs of different patients and the same patient at different stages of rehabilitation for breathing training and improving the training effect.

[0021] The breathing trainer includes a main body 100 and an air resistance component 200. The main body 100 has a breathing channel, and the air resistance component 200 is located in the breathing channel. The air resistance component 200 divides the breathing channel into an expiratory channel and an inspiratory channel, and the expiratory resistance and inspiratory resistance can be adjusted by adjusting the air resistance component 200.

[0022] The main body 100 comprises an exhalation regulator 110, an inhalation regulator 120, a base shell 130, and a mouthpiece 140. One end of the exhalation regulator 110 is closed, and the other end is open and rotatably connected to the first open end of the inhalation regulator 120. The second open end of the inhalation regulator 120 is movably connected to the first open end of the base shell 130, and the second open end of the base shell 130 is fixedly connected to the first open end of the mouthpiece 140, which communicates with the outside. The exhalation regulator 110, inhalation regulator 120, base shell 130, and mouthpiece 140 are internally interconnected, forming a breathing channel. The exhalation regulator 110 has a hollow hemispherical structure, and its closed end has multiple air vents 111. These air vents 111 connect the breathing channel to the outside, serving as the air inlet and outlet of the breathing channel. The inhalation regulator 120, the outer shell base 130, and the breathing nozzle 140 are all hollow cylindrical structures, with the second opening end of the breathing nozzle 140 serving as the inhalation and exhalation end of the breathing channel. The outer shell base 130 consists of an outer shell scale portion 131, an outer shell limiting portion 132, and an outer shell fixing portion 133, all of which are hollow cylindrical structures. The first opening end of the outer shell scale portion 131 is rotatably connected to the second opening end of the expiratory regulator 110. The outer shell limiting portion 132 is disposed on the second opening end of the outer shell scale portion 131. The first opening end of the outer shell fixing portion 133 is fitted onto the outer shell limiting portion 132 and fixedly connected to the second opening end of the outer shell scale portion 131. The outer shell limiting portion 132 is fixed to the second opening end of the outer shell scale portion 131 by the outer shell fixing portion 133, and the second opening end of the outer shell fixing portion 133 is fixedly connected to the first opening end of the breathing nozzle 140. The first opening end of the outer shell scale portion 131 serves as the first opening end of the outer shell base 130, and the second opening end of the outer shell fixing portion 133 serves as the second opening end of the outer shell base 130. The second opening end of the breathing mouthpiece 140 is provided with a mouth mask portion 141, which is used to cover the mouth to facilitate breathing training and also to prevent air leakage from affecting the effect of breathing training.

[0023] The air resistance assembly 200 comprises an expiratory fitting 210, an air resistance core 220, an inspiratory transmission component 230, and a reset elastic component 240. The air resistance core 220 is movably disposed within the breathing channel. Its closed end is axially slidably connected to the inspiratory regulator 120, and radially fixedly connected to the same component. This allows the air resistance core 220 to rotate when the inspiratory regulator 120 is rotated, without affecting its axial movement. The air resistance core 220 has a hollow cylindrical structure, with one end closed and the other open. The closed end of the air resistance core 220 has multiple expiratory through-holes 221, which are rotationally symmetrical, with each through-hole 221 forming a fan-shaped ring. The open end of the air resistance core 220 is movably and sealed to the inhalation port 134 of the outer shell base 130 via a sealing ring. The inhalation port 134 is located on the second open end of the outer shell limiting part 132. The exhalation mating part 210 is rotatably connected to the closed end of the air resistance core 220. The exhalation mating part 210 is axially slidably connected to the exhalation regulating part 110 via the exhalation transmission part 250. At the same time, the exhalation mating part 210 is radially fixedly connected to the exhalation regulating part 110 via the exhalation transmission part 250. This allows the rotation of the exhalation regulating part 110 to drive the exhalation transmission part 250 to rotate the exhalation mating part 210 relative to the air resistance core 220 without affecting the axial movement of the exhalation transmission part 250 and the exhalation mating part 210. The exhalation coordination component 210 has multiple exhalation coordination holes 211, arranged in the same way as the exhalation through holes 221, i.e., the multiple exhalation coordination holes 211 are rotationally symmetrical, and each exhalation coordination hole 211 is fan-shaped. When the exhalation adjustment component 110 rotates, causing the exhalation coordination component 210 to rotate relative to the air resistance core component 220, the overlap between the exhalation through hole 221 and the exhalation coordination hole 211 is adjusted, thereby regulating the airflow and adjusting the exhalation resistance. This adjustment method allows the user to precisely control the resistance during exhalation according to their own situation, improving the targeting of training. In addition, the exhalation coordination component 210 has an exhalation closure part 212, which covers the exhalation coordination holes 211. The exhalation closure part 212 is a thin sheet structure. When exhaling using the breathing trainer, the airflow can blow up the exhalation closure 212 to expose the exhalation mating hole 211, and the airflow flows out through the exhalation mating hole 211; when inhaling using the breathing trainer, the airflow can press the exhalation closure 212 against the exhalation mating member 210 to close the exhalation mating hole 211. This design ensures the independence of the airflow path during exhalation and inhalation and avoids mutual interference.During exhalation training, the passage between the air passage 111, the exhalation matching hole 211, the exhalation passage 221, the second opening end of the air resistance core 220, the second opening end of the outer shell base 130, and the second opening end of the breathing mouthpiece 140 constitutes the exhalation channel.

[0024] The suction transmission component 230 has a hollow cylindrical structure. Its first open end is screwed onto the air resistance core 220, and its second open end is axially slidably connected to the inner wall of the outer casing base 130. Multiple suction through holes 231 are provided on the side of the suction transmission component 230, connecting the hollow portion of the outer casing base 130 with the suction through-hole 134. A reset elastic component 240 is located between the suction transmission component 230 and the suction through-hole 134. One end of the reset elastic component 240 presses against the first open end of the suction transmission component 230, and the other end presses against the suction through-hole 134. The rotating inhalation adjustment component 120 drives the air resistance core component 220 to rotate, causing the inhalation transmission component 230 to move axially. This adjusts the relative position of the inhalation transmission component 230 and changes the compression force of the reset elastic component 240, thereby adjusting the inhalation resistance. In this way, the resistance to be overcome during inhalation can be flexibly changed to meet the needs of different training intensities. Under the action of the reset elastic component 240, the second open end of the air resistance core component 220 is kept in a sealed connection with the inhalation on / off port 134. When inhaling using the breathing trainer, if the airflow pressure is greater than the compression force of the reset elastic element 240, it can push the air resistance core 220 to move axially, causing the second opening end of the air resistance core 220 to separate from the inhalation cut-off port 134, allowing airflow to flow to the second opening end of the outer shell base 130. When the airflow pressure is less than the compression force of the reset elastic element 240, the second opening end of the air resistance core 220 is restored to a sealed connection with the inhalation cut-off port 134 under the action of the reset elastic element 240. This process ensures the normal opening and closing of the airflow path during inhalation, guaranteeing the smooth progress of inhalation training. During inhalation training, the passage between the air passage 111, the inhalation passage 231, the inhalation cut-off port 134, the second opening end of the outer shell base 130, and the second opening end of the breathing mouthpiece 140 constitutes the inhalation channel. In this embodiment, the outer shell scale portion 131 is made of transparent material and is marked with an inhalation resistance scale, which corresponds to the position of the inhalation transmission component 230. The second open end of the intake transmission component 230 is axially slidably connected to the inner wall of the housing limiting part 132. The reset elastic component 240 is a spring. The spring has good elastic properties and can stably realize the reset function, ensuring the reliability of intake resistance adjustment.

[0025] The working process of this breathing trainer is as follows: Before exhalation training, the user can rotate the exhalation regulator 110 to drive the exhalation transmission component 250 to rotate the exhalation mating component 210 relative to the air resistance core component 220, thereby adjusting the overlap between the exhalation through-hole 221 and the exhalation mating hole 211, and thus setting a suitable exhalation resistance. During training, the user places their mouth against the mouthpiece 141 of the breathing mouthpiece 140 and exhales air from their mouth. The exhaled airflow enters the breathing channel through the second opening end of the breathing mouthpiece 140. At this time, the airflow pressure blows open the exhalation closure part 212 on the exhalation mating component 210, exposing the exhalation mating hole 211. The airflow passes sequentially through the second opening end of the outer shell base component 130, the second opening end of the air resistance core component 220, the exhalation through-hole 221, and the exhalation mating hole 211, and finally exits from the air passage 111 at the closed end of the exhalation regulator 110, completing one exhalation training session.

[0026] Before performing inhalation training, the user can rotate the inhalation adjustment component 120 to drive the air resistance core component 220 to rotate, thereby driving the inhalation transmission component 230 to move axially and change the compression force of the reset elastic component 240, thus setting a suitable inhalation resistance. During training, the user places their mouth against the mouthpiece 141 and inhales from the outside. The outside air first enters through the air passage 111 at the closed end of the exhalation regulator 110, and then flows through the inhalation passage 231 and the inhalation cut-off port 134 on the side of the inhalation transmission component 230. If the airflow pressure is greater than the compression force of the reset elastic component 240, it will push the air resistance core 220 to move axially, causing the second opening end of the air resistance core 220 to separate from the inhalation cut-off port 134. The airflow can then flow to the second opening end of the outer shell base 130 and be inhaled by the user through the second opening end of the mouthpiece 140. When the airflow pressure is less than the compression force of the reset elastic component 240, under the action of the reset elastic component 240, the second opening end of the air resistance core 220 and the inhalation cut-off port 134 are restored to a sealed connection, completing one inhalation training session.

[0027] In summary, this respiratory trainer, through the synergistic action of its main body and air resistance components, successfully separates the respiratory channel into independent expiratory and inspiratory channels, and enables separate adjustment of expiratory and inspiratory resistance. This design solves the problem in existing respiratory trainers where expiratory and inspiratory resistance can only be adjusted synchronously. It can meet the precise needs of different patients and the same patient at different stages of rehabilitation, improving the targeting and effectiveness of respiratory training. This helps respiratory medicine patients better perform lung capacity exercises and promotes recovery.
