Description

Technical Field

[0001] This utility model belongs to the field of pulmonary function rehabilitation training technology, specifically relating to a portable pulmonary function rehabilitation training device. Background Technology

[0002] Lung damage, post-operative conditions, chronic cough, and decreased respiratory muscle strength can all impair normal lung function, leading to decreased oxygen intake, increased respiratory rate, weak cough, and difficulty expectorating phlegm. In such cases, doctors often recommend pulmonary function exercises to improve respiratory muscle strength, chest expansion, and vital capacity. There are many types of pulmonary function exercises, with blowing up balloons being particularly suitable for initial lung function training and for patients with limited mobility. Existing pulmonary function training devices operate on a similar principle. Breathing training is a common method in pulmonary function rehabilitation, typically using a breathing trainer. By adjusting resistance or volume, it helps patients perform deep breathing and slow exhalation, enhancing respiratory muscle strength and endurance. However, existing pulmonary function training devices have a simple structure, lack convenient adjustment of expiratory resistance, and cannot adjust training intensity according to the patient's recovery progress, making it difficult to meet the needs of different users and thus limiting their usability.

Detailed Implementation

[0018] The following detailed implementation methods further illustrate the following:

[0019] Please see Figure 1 , Figure 2 as well as Figure 3 This utility model discloses a portable pulmonary function rehabilitation trainer, comprising a training device housing 1, an exhalation nozzle 2, and a resistance component 3. In this embodiment, the resistance component 3 includes a piston plate 31, an adjusting rod 32, an adjusting nut 33, and an elastic element 34. Specifically, the piston plate 31 is longitudinally and slidably connected within the training device housing 1 to divide the training device housing 1 into an upper chamber 11 and a lower chamber 12. The lower end of the adjusting rod 32 is connected to the piston plate 31, and the upper end extends upward through the top wall of the training device housing 1. The adjusting nut 33 is threaded to the outside of the adjusting rod 32. The elastic element 34 is disposed within the upper chamber 11 to push the piston plate 31 downward. The exhalation nozzle 2 is connected to the training device housing 1 and communicates with the lower chamber 12. The top of the training device housing 1 has an exhaust port 13 communicating with the upper chamber 11. This invention utilizes a resistance assembly 3 consisting of a piston plate 31, an adjusting rod 32, an adjusting nut 33, and an elastic element 34. Rotating the adjusting nut 33 adjusts the position of the adjusting rod 32, thereby changing the position of the piston plate 31 and the degree of compression of the elastic element 34. This allows for convenient adjustment of expiratory resistance, enabling patients to flexibly adjust the training intensity according to their rehabilitation progress. This meets the needs of different users and overcomes the limitations of existing pulmonary function training devices.

[0020] In this embodiment, the training device housing 1 is made of transparent material, and the outer surface of the training device housing 1 is provided with scale markings 14 for measuring the distance between the piston plate 31 and the top of the training device housing 1. The transparent material of the training device housing 1 allows the user to directly observe the internal structure and operation of the trainer. This not only increases the fun and intuitiveness of training, but also makes it easier for the user to promptly identify potential problems inside the trainer, such as whether impurities have entered or whether components are damaged, facilitating timely handling and maintenance. Specifically, in this embodiment, the training device housing 1 is made of PC plastic. PC plastic has high transparency, high strength, and good temperature resistance. Since the training device housing 1 needs to be disinfected after use, the training device housing 1 made of PC plastic can be disinfected at high temperatures. To facilitate cleaning by the patient, in this embodiment, the training device housing 1 includes an upper housing 15 and a lower housing 16, and the upper housing 15 and the lower housing 16 are detachably connected. The detachable connection of the upper housing 15 and the lower housing 16 makes it convenient to clean and maintain the internal parts of the trainer after a period of use. The upper housing 15 and lower housing 16 can be separated to clean or replace internal components, ensuring the cleanliness and hygiene of the trainer's interior, extending its lifespan, and ensuring the safety and effectiveness of training. This also facilitates the installation and removal of the resistance components. Specifically, the lower housing 16 has a first external thread 161 at its top, and the upper housing 15 has a first internal thread 151 at its bottom that matches the external thread 161. The upper housing 15 and lower housing 16 are threaded together via the first internal thread 151 and the first external thread 161. This threaded connection makes the connection between the upper housing 15 and lower housing 16 tighter and more secure, effectively preventing gas leakage and ensuring the normal operation of the trainer. Furthermore, the threaded connection is simple to operate, easy to disassemble and install, and convenient for users to maintain and service the trainer.

[0021] In this embodiment, auxiliary handles 5 are symmetrically arranged on both sides of the upper housing 15. The auxiliary handles 5 facilitate the user's grip on the training device during training, improving comfort and stability. Especially for users with weak hand strength or physical disabilities, the auxiliary handles 5 provide better support and control, making training smoother. The bottom end of the lower housing 16 is provided with an air inlet pipe 4 integrally formed with the lower housing 16. The air inlet pipe 4 has a second internal thread 41, and the exhalation nozzle 2 has a second external thread 21 that matches the second internal thread 41. The exhalation nozzle 2 and the air inlet pipe 4 are threadedly connected via the second internal thread 41 and the second external thread 21. The integral design of the air inlet pipe 4 with the lower housing 16 enhances the structural strength of the air inlet pipe 4 and reduces the risk of gas leakage due to loose connections. The threaded connection between the exhalation nozzle 2 and the air inlet pipe 4 facilitates the installation and removal of the exhalation nozzle 2, allowing for the replacement of different sizes of exhalation nozzle 2 to meet the needs of different users, and also facilitating the cleaning and disinfection of the exhalation nozzle 2. To prevent backflow of gas, a one-way valve (not shown in the figure) is installed inside the exhalation nozzle. The one-way valve ensures that gas can only enter the trainer from the user's exhalation, preventing backflow and avoiding external gas from entering the body through the exhalation nozzle 2. This ensures the accuracy and stability of airflow direction during breathing training, making the training process more consistent with the body's normal respiratory physiology and providing a stable and reliable airflow environment for pulmonary function rehabilitation training. It effectively prevents the backflow of exhaled gas, reducing the spread of bacteria, viruses, and other microorganisms in exhaled gas between the trainer and the external environment. This protects the user from potential external contamination and prevents the user's exhaled gas from contaminating the trainer and its surrounding environment. Especially when multiple people share the trainer, it reduces the risk of cross-infection and improves the hygiene and safety of the trainer's use. The one-way valve ensures that airflow can only flow in one direction during exhalation, allowing the user to focus more on the exhalation action, more effectively train respiratory muscles, enhance exhalation strength and control, and contribute to improving the effectiveness of pulmonary function rehabilitation training and better improving lung ventilation function.

[0022] In this embodiment, the piston plate 31 is fixedly connected to one end of the adjusting rod 32. The elastic element 34 is a helical spring, which is sleeved on the outside of the adjusting rod 32, and its two ends abut against the top wall of the piston plate 31 and the inner top wall of the training device housing 1, respectively. During installation, the helical spring is first sleeved on the outside of the adjusting rod 32, and then the end of the adjusting rod 32 away from the piston plate 31 is passed through the top of the upper housing 15 and threadedly fixed to the adjusting nut 33. Due to the action of the adjusting nut 33, the adjusting rod 32 cannot slide down, and at this time, the two ends of the helical spring abut against the top wall of the piston plate 31 and the inner top wall of the training device housing 1, respectively. In order to facilitate the patient to adjust the initial position of the piston plate 31, in this embodiment, the resistance component 3 has two adjusting rods 32 and two adjusting nuts 33, which are spaced apart from each other, and the two adjusting nuts 33 are respectively assembled on the two adjusting rods 32. Specifically, when the adjusting rod 32 is at the center of the piston plate 31, during adjustment, because the adjusting nut 33 is threadedly connected to the adjusting rod 32, rotating the adjusting nut 33 with one hand will, according to the principle of interaction of forces, cause the adjusting nut 33 to exert a reaction force on the adjusting rod 32. If the other hand is not used to hold the adjusting rod 32, this reaction force will cause the adjusting rod 32 and the connected piston plate 31 to rotate together, making it impossible for the adjusting nut 33 to move smoothly on the adjusting rod 32, thus preventing the adjustment of the position of the piston plate 31. Therefore, in this case, one hand must be used to hold the adjusting rod 32 to prevent it from rotating, so that the other hand can smoothly rotate the adjusting nut 33 to change the position of the piston plate 31. When the adjusting rod 32 is not at the center of the piston plate 31, from an operational perspective, the user can adjust it with one hand because the adjusting rod 32 is off-center. However, there is a drawback in this case. Because the support point of the adjusting rod 32 on the piston plate 31 is not centered, the force applied by the adjusting rod 32 to the piston plate 31 will be uneven when the adjusting nut is rotated, resulting in the piston plate 31 being subjected to a force biased to one side. This biased force will cause the piston plate 31 to slide off-center within the training device housing, affecting the seal between the piston plate and the housing, and thus affecting the normal use of the trainer. At the same time, this offset will also make the adjustment inaccurate, unable to be precisely adjusted to the required position. Two adjusting rods 32 can support the piston plate 31 from different positions. Compared to a single adjusting rod 32, they can distribute the force on the piston plate 31 more evenly, keeping the piston plate 31 in a more stable state within the training device housing. Even during adjustment, the piston plate 31 is less prone to shifting or tilting due to the support of the two adjusting rods 32. Using both adjusting rods 32 simultaneously, the user only needs to turn one of the adjusting nuts 33 with one hand to adjust the position of the piston plate 31. When one of the adjusting nuts 33 is turned, the other adjusting rod 32 restricts the rotation and offset of the piston plate 31, allowing for smooth one-handed operation while ensuring the accuracy and stability of the adjustment.Moreover, this one-handed adjustment method is more convenient and faster, improving the user's operating experience.

[0023] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
