Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a breathing trainer with adjustable airflow resistance. Background Technology

[0002] Breathing training involves training the muscle groups used during inhalation. When a person inhales normally, the diaphragm and external intercostal muscles contract. When inhaling forcefully, accessory inhalation muscles, such as the trapezius and scalene muscles, are also needed. The contraction of these muscles causes the diaphragm to rise and the chest cavity to expand to its limit. Therefore, it is necessary to train the inspiratory muscles. Most breathing trainers use the basic principle of resistance training. When users inhale through the breathing trainer, they need to exert effort to resist the resistance set by the trainer in order to increase the strength of the inspiratory muscles, thereby increasing the strength and endurance of the respiratory muscles.

[0003] When using a breathing trainer for breathing training, different users require different levels of breathing training intensity, or patients at different stages of rehabilitation. If the same intensity of breathing training is applied to different users or patients at different stages of rehabilitation, the effectiveness of the breathing training will be reduced. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a breathing trainer with adjustable airflow resistance, which aims to solve the problem that different users need different breathing training intensities in the prior art, and that the effect of breathing training will be reduced if different users are given the same intensity of breathing training.

[0005] This utility model provides a breathing trainer with adjustable airflow resistance, including a valve body, an adjustment structure, and a mouthpiece. The adjustment structure is disposed on the valve body, and the valve body has an airflow channel. A spring and a ball are disposed in the airflow channel. One end of the spring abuts against the adjustment structure, and the other end abuts against the ball. The spring is used to push the ball to block the airflow channel, and the adjustment structure is used to adjust the elastic force applied by the spring to the ball.

[0006] Furthermore, the adjustment structure includes a screw and a nut. One end of the screw is threaded to the valve body and abuts against the spring, while the other end extends out of the valve body and is connected to the nut. The nut can be screwed to adjust the elastic force applied by the spring to the ball.

[0007] Furthermore, the nut includes a top wall and a side wall, the top wall and the side wall forming an insertion space, the insertion space allowing the valve body to be inserted, and the screw being connected to the top wall.

[0008] Furthermore, a first scale is provided on the side wall, the first scale being evenly spaced around the periphery of the side wall, and the first scale being used to measure the angle of the nut being turned.

[0009] Furthermore, the valve body is provided with a second scale, which is used to measure the distance that the nut is displaced by screwing it onto the valve body.

[0010] Furthermore, the nut is provided with anti-slip stripes.

[0011] Furthermore, the airflow channel includes a first channel, a second channel, and an adjustment channel. The central axis of the first channel coincides with the central axis of the screw and is connected to the bite nozzle. The central axis of the first channel is perpendicular to the central axis of the screw. The first channel and the second channel are connected through the adjustment channel. The spring and the ball are disposed in the adjustment channel.

[0012] Furthermore, the adjustment channel includes a conical surface connected to the inner peripheral wall of the first channel, and the diameter of the bead is larger than the diameter of the first channel.

[0013] Furthermore, the mouthpiece includes a wrapping portion and a transverse portion, the transverse portion protruding from the inner peripheral wall of the wrapping portion, the wrapping portion being used to abut against the mouth, and the transverse portion being available for teeth to bite.

[0014] Furthermore, the transverse portion has a protruding longitudinal portion, and the longitudinal portion and the wrapping portion together form a space that can accommodate the teeth.

[0015] Beneficial Effects: This utility model provides a breathing trainer with adjustable airflow resistance, including a valve body, an adjustment structure, and a mouthpiece. The adjustment structure is located on the valve body, which has an airflow channel. A spring and a ball are located within the airflow channel. One end of the spring abuts against the adjustment structure, and the other end abuts against the ball. The spring pushes the ball to block the airflow channel, and the adjustment structure adjusts the elastic force applied by the spring to the ball. Therefore, during breathing training, the elastic force applied by the spring to the ball can be adjusted by the adjustment structure, thus changing the training intensity of the breathing trainer. The force required for the user to push the ball away during exhalation also varies, thereby meeting the different intensity of breathing training needs of various users or the needs of patients at different stages of rehabilitation.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a breathing trainer with adjustable airflow resistance, including a valve body 1, an adjustment structure 2, and a mouthpiece 3. The adjustment structure 2 is disposed on the valve body 1. The valve body 1 has an airflow channel 11. A spring 4 and a ball 5 are disposed in the airflow channel 11. One end of the spring 4 abuts against the adjustment structure 2, and the other end abuts against the ball 5. The spring 4 is used to push the ball 5 to block the airflow channel 11. The adjustment structure 2 is used to adjust the elastic force applied by the spring 4 to the ball 5.

[0022] Specifically, in this application, under the elastic force of the spring 4, the bead 5 can block the airflow channel 11. When the user performs breathing training, they need to exhale to overcome the resistance of the spring 4 on the bead 5, thereby opening the airflow channel 11. By adjusting the elastic force applied by the spring 4 to the bead 5 through the adjusting structure 2, the training intensity of the breathing trainer can be changed, and the force required for the user to push the bead 5 open during exhalation will also be different, thus meeting the breathing training needs of different users at different intensities, or meeting the needs of patients at different stages of rehabilitation.

[0023] In one feasible embodiment, the adjusting structure 2 includes a screw 21 and a nut 22. One end of the screw 21 is threadedly connected to the valve body 1 and abuts against the spring 4, while the other end extends outside the valve body 1 and connects to the nut 22. The nut 22 can be screwed to adjust the elastic force exerted by the spring 4 on the ball 5. Specifically, by turning the nut 22, the screw 21 is driven to rotate, causing the screw 21 to move within the valve body 1, thereby changing the deformation of the spring 4 and thus changing the magnitude of the elastic force exerted by the spring 4 on the ball 5.

[0024] In one feasible embodiment, the nut 22 includes a top wall 221 and a side wall 222, which together form an insertion space for the valve body 1 to be inserted. The screw 21 is connected to the top wall 221. In this embodiment, the torque of the nut 22 can be increased, thereby enabling precise control of the resistance.

[0025] In one feasible embodiment, a first scale 223 is provided on the sidewall 222. The first scale 223 is evenly spaced around the circumferential sidewall 222 of the sidewall 222, and is used to measure the angle of the screw nut 22 being turned. In this embodiment, the first scale 223 facilitates precise control of resistance. For example, each turn of the screw nut 22 by one scale increment can sense the increase or decrease in resistance, thereby quickly adjusting the screw nut 22 to a scale that suits its resistance level.

[0026] In one feasible embodiment, the valve body 1 is provided with a second scale 224, which is used to measure the distance the nut 22 is displaced by screwing onto the valve body 1. In this embodiment, the second scale 224 allows the patient or doctor to quantitatively adjust the resistance level to meet different resistance needs of the user and to be suitable for different stages of rehabilitation training.

[0027] In one feasible embodiment, the nut 22 is provided with anti-slip stripes 225.

[0028] In one feasible implementation, the airflow channel 11 includes a first channel 111, a second channel 112, and an adjustment channel 113. The central axis of the first channel 111 coincides with the central axis of the screw 21 and is connected to the mouthpiece 3. The central axis of the first channel 111 is perpendicular to the central axis of the screw 21. The first channel 111 and the second channel 112 are connected through the adjustment channel 113. The spring 4 and the ball 5 are disposed within the adjustment channel 113. Specifically, during exhalation, the gas flow path is: mouthpiece 3—first channel 111—adjustment channel 113—second channel 112. The second channel 112 is used to connect with the external environment to facilitate gas expulsion.

[0029] In one feasible embodiment, the adjustment channel 113 includes a tapered surface 114 connected to the inner peripheral wall of the first channel 111, and the diameter of the bead 5 is larger than the diameter of the first channel 111. The tapered surface 114 provides space for the bead 5 to move and also prevents the adjustment channel 113 from being completely blocked. The larger diameter of the bead 5 than the diameter of the first channel 111 prevents the bead 5 from entering the first channel 111.

[0030] In one feasible embodiment, the mouthpiece 3 includes a wrapping portion 31 and a transverse portion 32. The transverse portion 32 protrudes from the inner peripheral wall of the wrapping portion 31. The wrapping portion 31 is used to abut against the mouth, and the transverse portion 32 is available for teeth to bite. When the user uses the mouthpiece 3, the wrapping portion 31 is close to the mouth, the upper and lower teeth bite down on the transverse portion 32, and then the user exhales into the mouthpiece 3.

[0031] In one feasible embodiment, the transverse portion 32 has a protruding longitudinal portion 33, which, together with the covering portion 31, forms a space capable of accommodating the teeth. In this embodiment, the longitudinal portion 33 abuts against the inner side of the teeth during exhalation, thereby effectively preventing the mouthpiece 3 from being ejected during exhalation.
