Description

Technical Field

[0001] The present invention relates to the field of respiratory therapy in the pulmonary department, and mainly relates to a breathing trainer that simultaneously has inspiratory and expiratory muscle exercises. Background Art

[0002] With the changes in modern technology and lifestyle, the air quality deteriorates, the process of population aging in society accelerates, etc. The incentives for lung diseases increase, leading to various chronic lung diseases, such as chronic obstructive pulmonary disease, asthma, emphysema, or some acute lung diseases, such as cough, influenza, tracheitis or bronchitis. In some patients, the airway will be blocked by sputum; the sputum that cannot be discharged often causes various lung function disorders such as cough, dyspnea, and shortness of breath when moving, seriously reducing the quality of life of the patient, affecting the lung function of the patient, and increasing its susceptibility to bacteria and viruses; when the patient cannot cough out by himself, a sputum aspirator is often used to aspirate, which is more likely to cause airway damage.

[0003] In addition to exhalation sputum drainage training, inspiratory muscle training also plays an important role in lung function rehabilitation. Strengthening the strength of the diaphragm and other inspiratory muscle groups during inspiration can effectively improve the ventilation function of the lungs, reduce dyspnea, and enhance the sputum drainage ability. Regular inspiratory muscle training helps to improve the lung expansion ability of the patient and enhance the endurance of the respiratory muscles, so as to better meet the normal breathing needs in life activities.

[0004] Most of the existing breathing trainers on the market have only a single expiratory training function and no inspiratory training function. The breathing training is adjusted by a ball head structure. When exhaling, the ball head is rotated and opened; if the expiratory intensity is insufficient or the angle is skewed during exhalation, the training effect cannot be achieved, which is not convenient for sputum drainage, and the user needs to use it correctly to achieve the actual effect. A breathing trainer lacking an inspiratory function cannot fully meet the needs of lung function rehabilitation training. Its structure also limits the setting of the oscillation frequency, which has a certain impact on the sputum drainage effect during expiratory airway resistance training. For patients using a ventilator when coughing, the pressure in the ventilator circuit is too high, which is likely to cause lung injury.

[0005] For the breathing trainers with ball head structure and seesaw structure, it is difficult to achieve the preset breathing training effect due to the lack of accuracy or the angle skew during exhalation. In addition, there are few small and portable breathing trainers on the market, which limits the use of users in outdoor or home scenarios; the cultivation of normal breathing ability is less, resulting in a longer respiratory rehabilitation cycle and a slow treatment effect. Therefore, in addition to improving expiratory training, a function of strengthening inspiratory muscle training is also needed to accurately adjust the training intensity of inspiration and expiration, and help patients perform respiratory rehabilitation training more efficiently.

[0006] In view of the deficiencies of the prior art, the present invention provides a breathing trainer that simultaneously exercises the inspiratory and expiratory muscles.

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0028] SeeFigures 1 to 3 , shown in the figure is a breathing trainer that simultaneously exercises the inspiratory and expiratory muscles, including a respiratory phlegm evacuator body 10 and a fourth connector 25. The respiratory phlegm evacuator body 10 is horizontally arranged, and the fourth connector 25 is vertically arranged in the upper middle part of the respiratory phlegm evacuator body 10; the breathing trainer further includes a valve body, an adjustment component, and a phlegm evacuation component. The valve body is used to block or open the air flow channel inside the fourth connector 25, and the outer ring surface in the middle of the valve body matches the inner through-hole diameter of the fourth connector 25; The phlegm evacuation component is used to provide an upward opening movement stroke for the valve component. One end of the phlegm evacuation component is installed on the respiratory phlegm evacuator body, and the other end is installed on the top of the valve body; the adjustment component is used to provide a pressing force for the valve component to press down on the fourth connector 25. The adjustment component is sleeved on the outer periphery of the respiratory phlegm evacuator body and the phlegm evacuation component, and the adjustment component is used to adjust the pressing force of the valve component downward.

[0029] In the present invention, the adjustment component is sleeved on the outer periphery of the respiratory phlegm evacuator body and the phlegm evacuation component, and the other end of the phlegm evacuation component is press-connected to the valve component; the adjustment component adjusts the distance between the respiratory phlegm evacuator body and the phlegm evacuation component, thereby adjusting the magnitude of the pressing force of the phlegm evacuation component pressing down on the valve component, and the pressure is relatively stable; during the breathing process of the user, the air flow channel inside the fourth connector 25 is opened or blocked, and the valve body can be flushed open when the expiratory intensity is the greatest; a relatively large air flow pressure is generated to form a vibration wave inside the patient's airway, and the air flow pressure continuously changes through the continuous opening and closing of the valve, causing the sputum in the airway to shift, facilitating the patient to cough up the sputum.

[0030] Specifically, when the adjustment component slides left or right, the vertical distance between the respiratory phlegm evacuator body and the phlegm evacuation component is far or near, so that the downward pressure of the valve in the fourth connector 25 is small or large; the resistance for opening and closing the valve of the fourth connector 25 is adjusted, so that the expiratory intensity during the breathing training of the patient can be adjusted, which is suitable for the respiratory rehabilitation training of various mild and moderate pulmonary patients, helps the sputum to be coughed up; provides training for cultivating the ability to simulate normal breathing, shortens the treatment cycle; restores normal cardiopulmonary function, and the respirator is light and small, convenient for the patient to carry around.

[0031] In this preferred embodiment, the phlegm evacuation component includes a vibration member, a left positioning member, and a right positioning member. The bottom of the left positioning member is arranged at the left end of the top of the respiratory phlegm evacuator body 10, and the left positioning member is used to install and position the left end of the vibration member; the left end of the right positioning member is arranged at the right end of the top of the valve body, and the right positioning member is used to install and position the right end of the vibration member at the left end of the top surface of the valve body.

[0032] Further, the left positioning member includes a left positioning platform 51, a left fastening block 52, two left guiding columns 54, and a left buckle 53. The left positioning platform 51 is horizontally arranged at the left end of the top of the sputum aspiration device body 10; the left end of the left positioning platform 51 is hinged with the left fastening block 52, and the left buckle 53 is arranged at the left end of the left fastening block 52. The left fastening block 52 is rotated clockwise to fasten the left end of the vibrating member on the left positioning platform 51; the two left guiding columns 54 are vertically arranged on the top surface of the left positioning platform 51, and the two left guiding columns 54 are arranged in the radial direction of the sputum aspiration main body.

[0033] Further, the right positioning member includes a right positioning platform, a right fastening block 55, two right guiding columns 57, and a right buckle 56. The right positioning platform is horizontally arranged at the right end of the anti-disengagement plate 43 of the air valve main body; the left end of the right positioning platform is hinged with the right fastening block 55, and the bottom of the right buckle 56 is vertically and fixedly arranged at the right end of the right fastening block 55. The right fastening block 55 is rotated counterclockwise to fasten the right end of the vibrating member on the right positioning platform; the two right guiding columns 57 are respectively vertically arranged on the left and right sides of the anti-disengagement plate 43 of the air valve main body, and the two left guiding columns 54 and the two right guiding columns 57 are both arranged in the radial direction of the sputum aspiration main body. The right positioning platform is the anti-disengagement plate 43.

[0034] In this preferred embodiment, the vibrating member is a horizontally arranged elastic thin sheet 58; the height of the left guiding column 54 on the left is less than the height of the left guiding column 54 on the right, and the height of the right guiding column 57 on the right is less than the height of the left guiding column 54 on the left; two left guiding holes are arranged at the left end of the elastic thin sheet 58 and are respectively installed on the two left guiding columns 54, and two right guiding holes are arranged at the right end of the elastic thin sheet 58 and are respectively installed on the two right guiding columns 57. Specifically, the longitudinal section of the left fastening block 52 is in a π shape; in another embodiment, the left guiding column 54 and the right guiding column 57 can be respectively arranged as 1.

[0035] Further, the material used for the elastic thin sheet 58 includes but is not limited to: metals, alloys, polymer materials, plastics, etc. All materials that can meet its functional requirements are acceptable and fall within the protection scope of this invention patent; see Figure 2 , and the elastic thin sheet 58 can be made of a transparent material.

[0036] Further, the length of the elastic thin sheet 58 is 55 - 65 mm, and the vibration frequency of the elastic thin sheet 58 is 18 - 38 Hz / second; specifically, the vibration frequency of the elastic thin sheet 58 is preferably 16 - 40 Hz. A swing frequency of 16 - 40 Hz is beneficial for the directional swing of the cilia in the bronchi / trachea to push sputum from the small airways to the central airways for easy expectoration; in the preferred embodiment, the length of the elastic thin sheet 58 is 55 - 65 mm, and the vibration frequency of the elastic thin sheet 58 is 18 - 38 Hz / second; when the length of the elastic thin sheet 58 is 70 - 80 mm, the vibration frequency of the elastic thin sheet 58 is 16 - 25 Hz / second.

[0037] Elastic thin sheets 58 of the same material. For an object with a short length, the stroke of a single vibration is small and the time is short, and the shorter elastic thin sheet 58 has a higher vibration frequency. The vibration frequency is adjusted by adjusting the length of the elastic thin sheet 58, and the required vibration frequency is achieved by measuring the vibration frequency with a vibration frequency tester. The swinging of bronchial / tracheal cilia is crucial for the health of the respiratory system. The cilia swing regularly up and down (swing frequency 16 - 40 Hz), blocking inhaled dust, bacterial impurities, and discharging them out of the body, avoiding the accumulation of harmful substances in the airway, thereby protecting the airway from damage.

[0038] The left positioning member and the right positioning member are respectively arranged at both ends of the above air valve body. When the user breathes against the mouthpiece 12, the air valve body and the left end of the right positioning member are gradually lifted, effectively preventing the air valve body from being pushed open and disengaged.

[0039] The above vibrating member is designed as an elastic thin sheet 58. The elastic thin sheet 58 has a certain elasticity when swinging, which is convenient for self-adjusting the swinging angle appropriately and giving an appropriate buffering force. The heights of the inner left guiding column 54 and the right guiding column 57 are both higher than those of the outer side. The left fastening block 52 and the right fastening block 55 respectively prevent the elastic thin sheet 58 from being disengaged from the left guiding column 54 and the right guiding column 57 during the swinging process. The guiding effect of the left guiding column 54 and the right guiding column 57 is good. The connection between the left end of the elastic thin sheet 58 and the left guiding column 54 and between the right end and the right guiding column 57 is similar to a hinged connection, but the hinge points are not fixed, that is, they slide up and down along the left guiding column 54 and the right guiding column 57 respectively.

[0040] In this preferred embodiment, the adjusting assembly includes a pair of slide rails 31, a guiding sleeve 32, and a pressure frame 33. The pair of slide rails 31 are horizontally arranged on the outer ring surface of the respiratory expectoration device body 10 and are located between the left positioning member and the right positioning member. A pair of chutes are horizontally arranged on the inner wall of the guiding sleeve 32, and the pair of chutes of the guiding sleeve 32 are respectively slidably connected to the pair of slide rails 31. The bottom of the pressure frame 33 is fixedly arranged on the top of the guiding sleeve 32, and the vibrating member horizontally passes through the pressure frame 33. The height of the pressure frame 33 is not higher than the height of the left positioning member. The guiding sleeve 32 slides left or right along the axis direction of the respiratory expectoration device body 10, and the swinging angle of the right end of the vibrating member becomes larger or smaller. Preferably, the height of the pressure frame 33 is lower than the height of the left positioning member. Specifically, raised anti-disengagement blocks are respectively arranged at both ends of the pair of slide rails to prevent the guiding sleeve 32 from disengaging from the left and right ends of the pair of slide rails.

[0041] The guiding sleeve 32 of the above adjusting assembly slides horizontally left or right along the slide rails 31 and the elastic thin sheet 58. The downward pressure of the guiding sleeve 32 on the right end of the elastic thin sheet 58 gradually increases, gradually increasing the downward pressure on the top of the air valve body. The resistance for the air valve body to disengage upward gradually increases, and the exhalation force at the mouthpiece 12 also needs to gradually increase.

[0042] Further, the adjusting component further includes a pressure spring 35. The bottom of the pressure spring 35 is longitudinally clamped to the top of the air valve body, and the top of the pressure spring 35 abuts against the inner wall of the outer cover 60 of the respiratory expectoration device.

[0043] The above-mentioned pressure spring 35 double-guarantees the stability of the downward pressure of the air valve body and also prevents the air valve body from disengaging from the fourth connector 25.

[0044] In this preferred embodiment, the inner through-hole of the fourth connector 25 is in the shape of a frustum of a cone. The air valve body includes a frustum head 41 and an anti-disengagement plate 43. The outer shape of the middle and upper part of the frustum head 41 is in the shape of a frustum of a cone, and the outer shape of the lower part is in the shape of a hemisphere. The outer wall of the middle and upper part of the frustum head 41 is closely attached to the inner wall of the through-hole of the fourth connector 25; the second magnet is movably arranged inside the frustum head 41, and the anti-disengagement plate 43 is horizontally arranged on the outer periphery of the top of the frustum head 41.

[0045] Further, the top of the respiratory expectoration device body 10 is detachably covered with an outer cover 60, and the expectoration component is located inside the outer cover 60; a docking protrusion 61 is arranged on the inner wall of the left end of the outer cover 60, and a clamping table 63 is arranged on the inner wall of the right end; a docking groove 62 is arranged on the outer wall of the left end of the respiratory expectoration device body 10, and a clamping block 64 is vertically arranged at the top middle; the docking protrusion 61 is docked in the docking groove 62, and the buckle at the right end of the top of the clamping block 64 is clamped on the top surface of the clamping table 63; a plurality of decorative holes 83 are evenly spaced on the left and right sides of the outer cover 60, and the shapes of the plurality of decorative holes 83 are ellipses with different lengths. Specifically, a plurality of ventilation holes 65 are evenly spaced and penetrate through the top panel of the outer cover 60.

[0046] The left part of the above-mentioned outer cover 60 is docked to the left top of the respiratory expectoration device body 10, and the right part is clamped to the top of the respiratory expectoration device body 10, with firm connection and convenient disassembly.

[0047] Preferably, a first one-way valve 22 is arranged inside the first connector 21, and the first one-way valve 22 is conducted from bottom to top.

[0048] Embodiment 2, see Figure 4 and Figure 5, on the basis of Embodiment 2, the breathing trainer further includes an inhalation component and a mouthpiece 12. The inhalation component is used for inhalation training and includes a third connector and a third one-way valve 2424. A third connector is coaxially arranged at the left end of the breathing and sputum drainage device body, and a mouthpiece 12 is arranged at the right end in the length direction of the breathing and sputum drainage device body. A third one-way valve 24 is arranged inside the third connector, and the third one-way valve 24 conducts from left to right. The third one-way valve 24 includes a third valve body 71, a third valve piece 73, and a third adjusting disc 74. The third valve piece 73 is radially arranged on the inner wall of the third adjusting disc 74, and the third adjusting disc 74 is rotatably arranged on the right side of the third valve body 71. The fixed valve piece 72 of the third valve body 71 has the same cross-sectional shape as the radial cross-section of the third valve piece 73, that is, the fixed cross-section of the third valve body 71 and the radial movable cross-section of the third valve piece 73 are staggered to completely block the third connector.

[0049] Specifically, the cross-sectional shape of the fixed valve piece 72 of the third valve body 71 is a yin fish taiji pattern, and the cross-sectional shape of the movable valve piece of the third valve piece 73 is a yang fish taiji pattern. Rotate the third adjusting disc 74. When the yin fish taiji pattern of the third valve body 71 intersects with the yang fish taiji pattern of the third valve piece 73, the third connector is completely closed. In another embodiment, the fixed valve holes of the third valve body 71 are a plurality of round holes, and the diameters of the plurality of round holes gradually decrease along the circular ring path.

[0050] During operation, when the user exhales at the mouthpiece 12, the third valve piece 73 of the third one-way valve 24 moves to the right to block the air flow channel of the third valve body 71. When inhaling, the third valve piece 73 of the third one-way valve 24 moves to the right to be at the first connector 21, and then opens the air flow channel of the third valve body 71. After air enters, rotate and adjust the gear of the third adjusting disc 74. The overlapping area between the movable valve holes of the third valve piece 73 and the fixed valve holes of the third valve body 71 is the flow area of the third one-way valve 24. When the inhaled flow area becomes smaller, to achieve the same air inhalation volume, it is necessary to increase the inhalation intensity and inhalation flow rate. Therefore, the patient needs to inhale hard to achieve the purpose of exercising the inhalation muscles.

[0051] Embodiment 3, on the basis of Embodiment 1, a first connector 21 is vertically arranged at the lower left part of the breathing and sputum drainage device body. The first connector 21 is used to supplement fresh air from the outside into the breathing and sputum drainage device body 10. The first connector 21 includes a first outer cylinder and a first one-way valve 22. The first one-way valve 22 is arranged at the interface of the first outer cylinder, and the first one-way valve 22 conducts from top to bottom. A nebulizer is detachably connected to the bottom of the first connector 21, and the nebulizer is used to provide liquid medicine atomized mist at the mouthpiece 12. When atomizing, remove the airtight cover at the bottom of the first one-way valve 22. When performing inhalation and exhalation training, an external airtight cover needs to be used or an atomization cup needs to be connected.

[0052] Preferably, a plurality of modification holes 83 are evenly spaced apart on the left and right sides of the outer cover 60 , and the shapes of the plurality of modification holes 83 are ovals of varying lengths.

[0053] A pair of clamping strips 84 are arranged on both sides of the fourth connector 25 of the respiratory expectorant body 10, and the pair of clamping strips 84 are arranged along the axial direction of the respiratory expectorant body 10, and the shape of the pair of clamping strips 84 is an eight-shaped shape as a whole. The plurality of modification holes 83 can not only cover the internal expectoration component structure, ensure the aesthetics, but also increase the flow area of the outer cover 60.
