Description

Technical Field

[0001] The invention relates to the technical field of medical trainers, and in particular to a dual-mode adjustable resistance breathing trainer. Background Art

[0002] Breathing trainers are designed to help users improve their respiratory function, increase the strength and endurance of their respiratory muscles, and clear phlegm from their respiratory tracts. They are widely used in the management and rehabilitation of various respiratory diseases, and are also suitable for breathing exercises for the general population. With the continuous advancement of medical technology, people's demand for breathing trainers is also growing. In order to meet the needs of different trainees, the design of breathing trainers pays more and more attention to simple operation, convenient use, visualization and quantification of training effects, and pays more attention to scientificity and practicality. Currently, the commonly used types of respiratory trainers include positive pressure respiratory trainers, oscillating positive pressure respiratory trainers and inspiratory muscle trainers. Positive pressure respiratory trainers help keep the airway open and prevent airway collapse by generating positive pressure during exhalation. Representative products include Threshold PEP 735. Oscillating positive pressure respiratory trainers help loosen phlegm in the airway by combining positive pressure and oscillation effects, making it easier to cough up phlegm. Representative products include: Acapella Choi ce, "Lung Flute" and Qiyi Lung Super Breathing Trainer. Inspiratory muscle trainers help enhance the strength and endurance of the inspiratory muscles by providing adjustable resistance. Representative products include: POWERbreathe K5 and Ultrabreathe.

[0003] When adjusting the breathing resistance, the above-mentioned trainer can adjust the distance between the valve plate and the valve seat in the spring-type linear air valve or the preload of the spring. The larger the distance between the valve plate and the valve seat, the larger the airflow channel and the smaller the airflow resistance. The larger the preload of the spring, the greater the airflow resistance. Or the angle of the valve disc in the rotary annular air valve can be adjusted. The larger the angle of the valve disc, the larger the airflow channel and the smaller the airflow resistance. When adjusting the oscillation parameters, the above-mentioned trainer can adjust the length of the rocker in the rocker-type oscillation structure or the increase or decrease of the counterweight. The longer the length of the rocker, the larger the oscillation amplitude and the smaller the oscillation frequency. The heavier the counterweight, the smaller the oscillation amplitude and the smaller the oscillation frequency.

[0004] However, the training function of the above-mentioned trainer is single, and it cannot meet the training needs of the trainees in different stages or different modes at the same time. When the above-mentioned trainers need to be purchased separately to meet the training needs of the trainees, it is not convenient to reduce the medical burden, nor is it convenient to carry and keep. In addition, when the above-mentioned trainer is used to adjust the respiratory resistance or the oscillation parameter, the adjustment method is single, and the single adjustment method will increase the wear of the single structure. Therefore, there is a need for a dual-mode adjustable resistance respiratory trainer that can perform expiratory muscle + oscillation expectoration training mode, inspiratory muscle training mode, and is convenient for multi-mode respiratory resistance adjustment and oscillation parameter adjustment.

[0035] Embodiment 1

[0036] like Figure 1-Figure 5 and Figure 10-12As shown, a dual-mode adjustable resistance breathing trainer proposed by the present invention comprises a transparent outer seat body 1, a detachable mouthpiece 2 and a detachable nose clip 3 arranged outside the transparent outer seat body 1, the trainer body is an L-shaped seat body, and the detachable design of the detachable mouthpiece 2 and the detachable nose clip 3 can improve the convenience of carrying, the transparent outer seat body 1 is made of durable plastic material, and the transparent outer seat body 1 is composed of a front seat body 16, a middle seat body 17, a rear seat body 18 and a lower seat body 19, and the mounting surfaces of the front seat body 16, the middle seat body 17, the rear seat body 18 and the lower seat body 19 are connected to the lower seat body 19 through a sealing gasket 20 and a bolt 21. The seat body 19 is installed, and the detachable design of the transparent outer seat body 1 is convenient for subsequent cleaning and disinfection. The contact parts of the detachable mouthpiece 2 and the detachable nose clip 3 are made of medical grade silicone. The end of the front seat body 16 is fixedly connected with a plug-in rectangular sleeve 28 plugged with the detachable mouthpiece 2, and the top of the front seat body 16 is fixedly connected with a plug-in cylindrical sleeve 29. The outside of the plug-in cylindrical sleeve 29 is plugged with a connecting hose 30 connected with the detachable nose clip 3. When the detachable nose clip 3 closes the trainee's nose, it can ensure that the airflow passes through the detachable mouthpiece 2 and enters the interior of the horizontal airflow channel 4 to improve the training effect.

[0037] The front seat 16 is internally embedded with a power supply mechanism 22 and a timing and counting sensor 23 connected to the power supply mechanism 22. The timing and counting sensor 23 has the function of automatic timing and counting. The bottom of the timing and counting sensor 23 is provided with a sensing needle 24. The outside of the front seat 16 is embedded with a display screen 25. When the airflow passes through the detachable mouthpiece 2 and enters the horizontal airflow channel 4, the sensing needle 24 senses the timing and counting of the timing and counting sensor 23 and displays it through the display screen 25 to monitor the compliance of the exercise, thereby helping to evaluate the effect of the breathing training. The outside of the front seat 16 and the rear seat 18 is provided with a distance scale 26 close to the upper resistance insert 102 and the oscillating ball 112. The setting of the distance scale 26 can observe the moving distance of the upper resistance insert 102 and the moving distance of the oscillating ball 112. The outside of the lower seat 19 is symmetrically provided with a balance handle 27. The setting of the balance handle 27 is convenient for the trainer to hold the trainer in a horizontal state for use, and can also assist it to be placed on a desktop for use;

[0038] A horizontal airflow channel 4, an arc-shaped exhalation chamber 5 and a vertical oscillation chamber 6 are provided in sequence inside the transparent outer base body 1. The top of the horizontal airflow channel 4 is connected with a vertical inhalation chamber 7. A one-way self-resetting exhalation valve plate 8 that can be opened upward is provided on the side of the arc-shaped exhalation chamber 5 close to the horizontal airflow channel 4. When the exhalation muscle is trained through the detachable mouthpiece 2, the gas entering the horizontal airflow channel 4 will push the one-way self-resetting exhalation valve plate 8 to open upward. A one-way self-resetting inhalation valve plate 9 that can be opened downward is provided on the side of the vertical inhalation chamber 7 close to the horizontal airflow channel 4. When the inhalation muscle is trained through the detachable mouthpiece 2, external gas will enter through the vertical inhalation chamber 7 and push the one-way self-resetting inhalation valve plate 9 to open downward.

[0039] The horizontal airflow channel 4 is provided with a middle resistance regulating structure 10 for regulating breathing resistance. The middle resistance regulating structure 10 comprises a convex groove 101 connected with the horizontal airflow channel 4. The convex groove 101 is slidably connected with an upper resistance plug 102 and a lower resistance plug 103 respectively located at the upper and lower positions of the horizontal airflow channel 4. When the upper resistance plug 102 and the lower resistance plug 103 slide in a direction approaching each other, the airflow resistance passing through increases. When the upper resistance plug 102 and the lower resistance plug 103 slide in a direction away from each other, the airflow resistance passing through decreases, thereby achieving the effect of regulating the airflow resistance. The convex groove 101 is symmetrically fixedly connected with a linkage hydraulic cylinder 106. The upper end of the linked hydraulic cylinder 106 is provided with an upper vertical piston rod 107 fixedly connected to the upper resistance plug 102, and the lower end of the linked hydraulic cylinder 106 is provided with a lower vertical piston rod 108 fixedly connected to the lower resistance plug 103, that is, the upper resistance plug 102 and the lower resistance plug 103 move synchronously and in opposite directions. The middle resistance adjustment structure 10 also includes a fixed screw sleeve 104 fixedly connected to the outside of the middle seat body 17, and the internal thread of the fixed screw sleeve 104 is connected to a rotating screw 105 rotatably connected to the upper resistance plug 102. By rotating the rotating screw 105, the upper resistance plug 102 and the lower resistance plug 103 can be moved up and down to adjust the airflow resistance;

[0040] The interior of the vertical oscillation chamber 6 is provided with an oscillating expectoration structure 11 for adjusting the oscillation parameters. The oscillating expectoration structure 11 includes a distance limiting ring 111 rotatably connected to the interior of the vertical oscillation chamber 6. An oscillating ball 112 is movably placed above the distance limiting ring 111. The oscillating ball 112 is a plastic ball with a certain weight. The smaller the weight of the oscillating ball 112, the smaller the oscillation amplitude and the greater the oscillation frequency. The distance limiting ring 111 is rotatably connected to the interior of the vertical oscillation chamber 6 through a rotating shaft 116. When the rotating shaft 116 drives the distance limiting ring 111 to rotate, the oscillating ball 112 can be driven to move up and down through the distance limiting ring 111. The oscillating ball 112 is a plastic ball with a certain weight. The smaller the weight of the oscillating ball 112, the smaller the oscillation amplitude and the greater the oscillation frequency. 2, the lower the position is, the smaller the oscillation amplitude is, and the greater the oscillation frequency is. The oscillating expectoration structure 11 also includes a limit rod 113 axially symmetrically fixedly connected to the outside of the rear seat body 18, and the outside of the axially symmetrical limit rod 113 is slidably connected to a rotating cylinder 114. A cross driving groove 115 is provided on the inner side of the rotating cylinder 114. The end of the rotating shaft 116 extends to the inside of the rotating cylinder 114 and is fixedly connected to a cross driving block 117 located inside the cross driving groove 115. By pressing the rotating cylinder 114 to disengage it from the limit rod 113, and then rotating the rotating cylinder 114, the position of the oscillating ball 112 can be changed to adjust the oscillation parameters.

[0041] A top resistance adjusting structure 12 for adjusting the exhalation resistance is provided at the top of the vertical oscillation chamber 6, and the top resistance adjusting structure 12 includes a fixed ventilation plate 121 fixedly connected to the top of the rear seat body 18 and communicated with the vertical oscillation chamber 6, and the outer axis of the fixed ventilation plate 121 is symmetrically rotated with a damping protrusion 124, and the outer sleeve of the fixed ventilation plate 121 is provided with a movable ventilation sleeve 122, and the outer side of the movable ventilation sleeve 122 is increased with anti-slip grooves, and the inner side of the movable ventilation sleeve 122 is symmetrically provided with a damping groove 125 adapted to the damping protrusion 124. The setting of the damping protrusion 124 and the damping groove 125 can increase the rotation resistance of the movable ventilation sleeve 122, and the smaller the overlap of the ventilation holes between the fixed ventilation plate 121 and the movable ventilation sleeve 122, the greater the resistance of the expiratory muscle training, and the bottom of the movable ventilation sleeve 122 is rotatably connected with a connecting sleeve 123 threadedly connected to the outside of the rear seat body 18.

[0042] The working principle of this embodiment is as follows: first, appropriate breathing training resistance and oscillating expectoration parameters are selected;

[0043] The upper resistance plug 102 can be moved up and down by rotating the rotating screw 105. When the upper resistance plug 102 moves downward, the upper vertical piston rod 107 can be driven to move downward, so that the lower vertical piston rod 108 drives the lower resistance plug 103 to move upward, that is, the upper resistance plug 102 and the lower resistance plug 103 move in a direction close to each other, and the air flow resistance through the horizontal air flow channel 4 is increased. When the upper resistance plug 102 moves upward, the upper vertical piston rod 107 can be driven to move upward, so that the lower vertical piston rod 108 drives the lower resistance plug 103 to move downward, that is, the upper resistance plug 102 and the lower resistance plug 103 move in a direction away from each other, and the air flow resistance through the horizontal air flow channel 4 is reduced, so that the effect of adjusting the breathing resistance can be achieved;

[0044] The rotating cylinder 114 can be pressed to disengage it from the limiting rod 113, and then the rotating cylinder 114 can be rotated to drive the limiting ring 111 to rotate through the cross driving groove 115, the cross driving block 117 and the rotating shaft 116. When the limiting ring 111 rotates clockwise, the limiting ring 111 can abut against the oscillating ball 112 and move upward. The more upward the position of the oscillating ball 112 is, the smaller its oscillation amplitude is and the larger its oscillation frequency is. When the limiting ring 111 rotates counterclockwise, the oscillating ball 112 can move downward due to its own gravity. The more downward the position of the oscillating ball 112 is, the larger its oscillation amplitude is and the smaller its oscillation frequency is, so that the effect of adjusting the oscillation parameters can be achieved.

[0045] The oscillation parameters can also be adjusted by replacing the oscillation balls 112 of different weights in the vertical oscillation chamber 6. The heavier the oscillation ball 112, the greater the oscillation amplitude and the smaller the oscillation frequency. The lighter the oscillation ball 112, the smaller the oscillation amplitude and the greater the oscillation frequency.

[0046] For beginners, they can choose an oscillating ball 112 with a smaller weight and an upward position to perform training with a smaller oscillation amplitude and a higher oscillation frequency.

[0047] For advanced trainers: they can choose an oscillating ball 112 with a larger weight and a downward position to perform training with a larger oscillation amplitude and a lower oscillation frequency;

[0048] The overlap of the vent holes between the fixed vent plate 121 and the movable vent sleeve 122 can be changed by rotating the fixed vent plate 121. The smaller the overlap of the vent holes between the fixed vent plate 121 and the movable vent sleeve 122, the greater the resistance to expiratory muscle training. On the contrary, the greater the overlap of the vent holes between the fixed vent plate 121 and the movable vent sleeve 122, the smaller the resistance to expiratory muscle training. At the same time, the resistance of the exhaled gas will in turn affect the oscillation frequency of the oscillating ball 112, so as to achieve the effect of adjusting the exhalation resistance and oscillation parameters.

[0049] Afterwards, maintain the correct sitting posture and start training;

[0050] When performing the expiratory muscle + oscillation expectoration training mode, the trainee needs to take a deep breath first, and then exhale into the horizontal airflow channel 4 through the detachable mouthpiece 2. The gas entering the horizontal airflow channel 4 passes through the upper resistance insert 102 and the lower resistance insert 103, pushes the one-way self-resetting exhalation valve plate 8 to open upward, and enters the arc-shaped exhalation chamber 5 and the vertical oscillation chamber 6 in turn. The gas entering the vertical oscillation chamber 6 pushes the oscillation ball 112 to rotate and oscillate repeatedly and is finally discharged through the fixed ventilation plate 121 and the movable ventilation sleeve 122;

[0051] After repeating the training for a specified period of time, the positive pressure and oscillation effects can be combined to assist the oscillation and discharge of sputum in the user's respiratory tract;

[0052] When performing the inspiratory muscle training mode, the trainee needs to exhale first, and then inhale into the horizontal airflow channel 4 through the detachable mouthpiece 2. The horizontal airflow channel 4 is in a negative pressure state, so that the one-way self-resetting exhalation valve plate 8 is tightly closed, and the external air passes through the vertical inhalation cavity 7, the upper resistance insert 102 and the lower resistance insert 103, and pushes the one-way self-resetting inhalation valve plate 9 to open downward and enter the interior of the horizontal airflow channel 4;

[0053] After repeating the training for a specified period of time, the effect of training the inspiratory muscle strength and endurance can be achieved;

[0054] After training, the trainer needs to be disassembled for cleaning and disinfection.

[0055] The main difference between the present embodiment and the prior art is that the present embodiment can perform expiratory muscle + oscillation expectoration training mode or inspiratory muscle training mode according to the selection to meet the training needs of the trainees in different stages or different modes. The expiratory muscle + oscillation expectoration training mode and the inspiratory muscle training mode can be switched freely without excessive operations; and the adjustment methods of the present embodiment are diverse to avoid increasing the wear of a single structure.

[0057] like Figure 1-Figure 3 and Figure 5-Figure 9 As shown, based on the first embodiment, the top of the vertical inhalation cavity 7 is connected with an upper accommodating groove 13, and a filter screen 14 is arranged inside the upper accommodating groove 13. The arrangement of the filter screen 14 can prevent dust in the air from entering the interior of the horizontal airflow channel 4. The one-way self-resetting exhalation valve plate 8 is in a vertical state or reset by its own gravity, and the one-way self-resetting inhalation valve plate 9 is in a horizontal state or reset by an external structure 15. If the one-way self-resetting inhalation valve plate 9 is in a horizontal state or reset only by its external torsion spring, the opening resistance of the one-way self-resetting inhalation valve plate 9 needs to be continuously overcome during inhalation muscle training, and the one-way self-resetting inhalation valve plate 9 is repeatedly opened and closed, which will damage its structure and affect its sealing performance.

[0058] The external structure 15 includes a vertical airtight cylinder 151 embedded in the middle seat body 17, the top of the vertical airtight cylinder 151 is fixedly connected to a horizontal airtight cylinder 152 extending to the outside of the middle seat body 17, the outside of the horizontal airtight cylinder 152 is evenly fixedly connected to an air pipe 153 facing the filter screen 14, the bottom of the vertical airtight cylinder 151 is fixedly connected to an arc-shaped airtight cylinder 154 located inside the horizontal air flow channel 4, and an arc-shaped piston rod 155 fixedly connected to the one-way self-resetting suction valve plate 9 is arranged inside the arc-shaped airtight cylinder 154 away from the vertical airtight cylinder 151. An electromagnetic block 157 is installed through the mounting frame 156, and the outside of the arc-shaped piston rod 155 is fixedly connected to a magnet block 158 located inside the arc-shaped airtight cylinder 152, and an arc-shaped return spring 159 is fixedly connected between the arc-shaped piston rod 155 and the mounting frame 156. When the electromagnetic block 157 is energized, it can adsorb the magnet block 158 and compress the arc-shaped return spring 159. When the electromagnetic block 157 is energized to adsorb the magnet block 158, the arc-shaped piston rod 155 will drive the one-way self-resetting air intake valve plate 9 to rotate downward to open the vertical air intake chamber 7, and allow the internal air to be discharged through the air pipe 153 to remove dust from the filter screen 14;

[0059] The external structure 15 also includes a middle channel 160 fixedly connected to the horizontal airflow channel 4, the interior of the middle channel 160 is rotatably connected to a two-way self-resetting breathing valve plate 161, the bottom of the middle channel 160 is connected to a lower accommodating groove 162, the interior of the lower accommodating groove 162 is fixedly connected to an insulating packaging tube 163, the inner bottom of the insulating packaging tube 163 is fixedly installed with an electric socket 164, the inner top of the insulating packaging tube 163 is movably provided with an insulating connecting column 165, the bottom of the insulating connecting column 165 is fixedly connected to an electric plug 166, the electric plug 166 is plugged into the electric socket 164 to energize the electromagnetic block 157, and the lower accommodating groove 1 The internal rotation connection of 62 is provided with a switch plate 167 and a connecting plate 168 which are fixedly connected to each other. A slide groove 169 is provided on the outside of the switch plate 167. The internal movably connected of the slide groove 169 is provided with a connecting shaft 170 which is rotationally connected to the insulating connecting column 165. When inhaling through the detachable mouthpiece 2, the two-way self-resetting breathing valve plate 161 deflects to the left and squeezes the switch plate 167, so that the electric plug 166 is connected to the electric socket 164 to energize the electromagnetic block 157. When exhaling through the detachable mouthpiece 2, the two-way self-resetting breathing valve plate 161 deflects to the right and squeezes the connecting plate 168, so that the electric plug 166 is disconnected from the electric socket 164 to cut off the power to the electromagnetic block 157.

[0060] The working principle of this embodiment: in the inspiratory muscle training mode, when inhaling into the interior of the horizontal airflow channel 4 through the detachable mouthpiece 2, the two-way self-resetting breathing valve plate 161 will deflect to the left and squeeze the switch plate 167 to a horizontal state. When the switch plate 167 rotates to a horizontal state, it will drive the electric plug 166 to plug into the electric socket 164 through the connecting shaft 170 and the insulating connecting column 165 to energize the electromagnetic block 157, and at the same time drive the connecting plate 168 to rotate to an inclined state. When the electromagnetic block 157 is energized to attract the magnet block 158, the arc piston rod 155 will drive the one-way self-resetting inhalation valve plate 9 to rotate downward to open the vertical inhalation cavity 7 and compress the arc reset spring 159, and at the same time squeeze the air inside the vertical airtight cylinder 151 and the arc airtight cylinder 152 into the horizontal airtight cylinder 152, so that the air is discharged through the air pipe 153 to remove dust from the filter screen 14;

[0061] During the expiratory muscle + oscillation expectoration training mode, when exhaling into the interior of the horizontal airflow channel 4 through the detachable mouthpiece 2, the gas will push the two-way self-resetting breathing valve plate 161 to deflect to the right and squeeze the connecting plate 168 to a horizontal state. The connecting plate 168 to a horizontal state will drive the switch plate 167 to rotate to an inclined state and drive the electric plug 166 to disconnect from the electric socket 164 through the connecting shaft 170 and the insulating connecting column 165 to cut off the power to the electromagnetic block 157. When the electromagnetic block 157 is powered off and separated from the magnet block 158, the arc-shaped reset spring 159 will drive the one-way self-resetting inhalation valve plate 9 to rotate upward through the arc-shaped piston rod 155 to close the vertical inhalation chamber 7.

[0062] The main difference between the present embodiment and the prior art is that when the present embodiment performs the inspiratory muscle training mode, the one-way self-resetting inspiratory valve plate 9 can open autonomously, and when the expiratory muscle + oscillation expectoration training mode is performed, the one-way self-resetting inspiratory valve plate 9 can close autonomously, so as to avoid the need to continuously overcome the opening resistance of the one-way self-resetting inspiratory valve plate 9 during inspiratory muscle training, thereby improving the inspiratory muscle training effect.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
