Description

Technical Field

[0001] This utility model relates to the field of respiratory muscle training technology, and in particular to a respiratory muscle endurance trainer. Background Technology

[0002] As the core power source for maintaining normal respiratory function, the strength and endurance of respiratory muscles directly affect an individual's respiratory efficiency, athletic performance, and the rehabilitation process of various respiratory diseases. In recent years, respiratory muscle training has been widely used as an effective adjunctive intervention in the rehabilitation treatment of patients with chronic obstructive pulmonary disease, asthma, and heart failure, as well as in areas such as improving the physical fitness of athletes and maintaining respiratory function in the elderly.

[0003] Most existing respiratory muscle training devices employ fixed resistance or adjustable resistance valve designs, applying constant resistance during inhalation or exhalation to train the inspiratory or expiratory muscle groups. Most devices can only train the inspiratory or expiratory muscles in a single mode, lacking an integrated design that allows for alternating inhalation and exhalation training on the same device. This results in a disjointed training process, failing to effectively simulate the rhythm and coordination of physiological breathing. Their resistance mechanisms are mostly static or stepped, maintaining a constant resistance value throughout breathing and failing to respond to dynamic changes in airflow pressure. This leads to users experiencing excessive resistance and discomfort at the beginning of breathing. Utility Model Content

[0004] The purpose of this invention is to provide a respiratory muscle endurance trainer that avoids the problem of constant resistance during breathing and inability to respond to dynamic changes in airflow pressure.

[0005] This utility model provides a respiratory muscle endurance training device, comprising: An air blowing pipe and an air suction pipe installed on one side are provided. The air blowing pipe and the air suction pipe are installed and fixed by a connector installed in the middle. An air nozzle is provided on the other side of the connector.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a respiratory muscle endurance trainer.

[0027] like Figures 1-7 As shown, this utility model embodiment provides a respiratory muscle endurance trainer, including an air blowing tube 200 for training the expiratory muscles, and an air inhalation tube 300 installed on one side for air intake. The air inhalation tube 300 trains the inspiratory muscles. The air blowing tube 200 and the air inhalation tube 300 are installed and fixed by a connector 100 installed in the middle. The other side of the connector 100 is provided with an air nozzle 400 to facilitate the user to blow and inhale.

[0028] An air-blowing pipe 200 has a baffle plate 230 installed inside to block the airflow. The baffle plate 230 is movably mounted on the upper end of a telescopic rod 233 fixedly mounted on one side of the baffle plate 230. A positioning rod 232 is movably mounted in the inner cavity of the telescopic rod 233. The middle of the telescopic rod 233 and the positioning rod 232 is buffered and controlled by a telescopic spring 234. An air outlet 270 is provided on the side of the air-blowing pipe 200 for air discharge. The baffle plate 230 is located in the middle of the pipe opening and the air outlet 270.

[0029] By setting an exhalation tube 200 and an inhalation tube 300 on both sides of the connector 100, the user can alternate between exhalation and inhalation on the same device, providing targeted endurance training for the expiratory and inspiratory muscle groups respectively. The exhalation tube 200 has a buffer adjustment mechanism consisting of a baffle plate 230, a telescopic rod 233, a positioning rod 232, and a telescopic spring 234. When the user blows, the airflow pushes the baffle plate 230 to move towards the outlet 270 against the elastic force of the telescopic spring 234, increasing the ventilation cross section and realizing dynamic resistance release. After the user stops blowing, the telescopic spring 234 resets and drives the baffle plate 230 back to its original position, restoring the initial resistance state. This structure simulates the pressure changes during physiological breathing, providing progressive and buffered resistance, avoiding damage to the respiratory tract from instantaneous high pressure, and improving training comfort and safety.

[0030] One end of the positioning rod 232 is fixedly connected to a positioning plate 231 for supporting the positioning rod 232. The middle part of the positioning plate 231 is provided with an adjusting tube 240 for adjusting the position of the positioning plate 231. The inner cavity of the adjusting tube 240 is provided with an adjusting screw 220 for adjusting in conjunction with the adjusting tube 240. The adjusting screw 220 is threadedly connected to the adjusting tube 240. The adjusting screw 220 is installed through the air blowing pipe 200 and is positioned by a bearing. The end is provided with a rotary knob 210 for rotating the adjusting screw 220.

[0031] Rotating the knob 210 drives the adjusting screw 220 to rotate within the adjusting tube 240, which in turn drives the adjusting tube 240 to move axially via threaded transmission. This changes the pre-compression of the telescopic spring 234 by the positioning disc 231. The adjustment of the pre-tension of the telescopic spring 234 directly determines the airflow pressure required for the barrier plate 230 to open, thus achieving stepless or graded precise adjustment of expiratory resistance. Users can flexibly set the resistance intensity according to their own lung function level, rehabilitation stage, or training goals, achieving progressive training from low-intensity recovery training to high-intensity endurance improvement, adapting to the personalized needs of different groups.

[0032] The inner cavity of the air blowing pipe 200 is provided with a limiting strip 250 for limiting the position of the barrier plate 230 and the positioning plate 231. The sides of the barrier plate 230 and the positioning plate 231 are provided with slots that match the size of the limiting strip 250. The limiting strip 250 and the slots together form a sliding guide and anti-disengagement limiting structure. This design effectively constrains the movement trajectory of the barrier plate 230 and the positioning plate 231 during the extension and retraction process, preventing them from rotating, tilting or jamming under the action of the spring or the impact of the airflow. This ensures that the barrier plate 230 is always facing the airflow direction and opens and closes smoothly, improving the accuracy of resistance adjustment and the reliability of device operation, and extending the service life of the equipment.

[0033] The upper end of the air tube 200 is provided with an observation port 260 for observing the position of the barrier plate 230. The upper end of the observation port 260 is marked with scale lines. The air tube 200 is internally equipped with a marker plate 235 for auxiliary position display. The marker plate 235 is fixedly installed inside the barrier plate 230, and its end can be marked with a conspicuous color. During training, the user can intuitively observe the position change of the marker plate 235 on the scale line, grasp the degree of displacement of the barrier plate 230 in real time, and thus judge the airflow intensity, duration and respiratory muscle exertion level. This visualization design not only enhances the interactivity and fun of training, but can also be used to assess the improvement of respiratory muscle endurance, provide a quantitative reference for rehabilitation progress, and improve the scientificity and effectiveness of training.

[0034] The inner side of the air valve 400 is provided with a biting part 410. The biting part 410 and the inner side of the air valve 400 are integrally molded and preferably made of silicone material. The integrally molded biting part 410 on the inner side of the air valve 400 conforms to the oral cavity structure and effectively relieves the pressure on the gums and lips caused by prolonged biting. The integrally molded structure has no splicing gaps, avoids bacterial growth, and ensures hygiene and safety. The silicone material has good elastic sealing performance, can fit tightly to the user's mouth, prevent air leakage, and ensure that all airflow passes through the internal channel of the trainer, ensuring accurate transmission of training resistance and improving training effect.

[0035] The blowing tube 200, the suction tube 300 and the air nozzle 400 are all threadedly installed on the upper end of the connector 100, and the lower end of the connector 100 is threadedly fitted with an operating handle 500 for easy gripping and use by the user, which facilitates connection and disassembly, as well as gripping and fixing during operation.

[0036] A protective filter 110 for blocking dust and saliva is embedded in the threaded interface between the air nozzle 400 and the connector 100. A protective filter 340 for blocking dust is provided at the end of the air intake pipe 300. The air intake and exhaust air are filtered to reduce the growth and contamination of bacteria inside the equipment.

[0037] The inhalation tube 300 includes a fixed tube 310 connected to the connector 100 and a rotating tube 320 mounted on one side for rotation. The fixed tube 310 and the rotating tube 320 are movably connected.

[0038] A protective cap 330 is threaded onto one end of the rotating tube 320. The second protective filter 340 is clamped by the rotating tube 320 and the protective cap 330, making it easy to disassemble and install.

[0039] A vent 321 for ventilation is fitted at the connection between the fixed tube 310 and the rotating tube 320. A connecting shaft 311 is installed at the axis of the fixed tube 310. The connecting shaft 311 is movably installed inside the connecting groove 322 opened in the rotating tube 320, allowing the rotating tube 320 to rotate around the axis of the connecting shaft 311. It has a built-in damping mechanism to achieve smooth, slow, and controllable movement. The vent 321 can be adjusted by rotating the rotating tube 320 to adjust the ventilation size, thereby adjusting the airflow speed of inhalation, which is convenient for exercising the inspiratory muscles.

[0040] The working principle of a respiratory muscle endurance trainer: By setting an air blowing tube 200 and an air inhalation tube 300 on both sides of the connector 100, the user can alternately exhale and inhale on the same device, providing targeted endurance training for the expiratory and inspiratory muscle groups respectively. The air blowing tube 200 has a buffer adjustment mechanism consisting of a baffle plate 230, a telescopic rod 233, a positioning rod 232, and a telescopic spring 234. When the user blows, the airflow pushes the baffle plate 230 to move towards the air outlet 270 against the elastic force of the telescopic spring 234, increasing the ventilation cross section and realizing dynamic resistance release. After the user stops blowing, the telescopic spring 234 resets and drives the baffle plate 230 back to its original position, restoring the initial resistance state. This structure simulates the pressure changes during physiological breathing, providing progressive and buffered resistance, avoiding damage to the respiratory tract caused by instantaneous high pressure, and improving training comfort and safety.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
