Description

Technical Field

[0001] The invention relates to the technical field of pulmonary respiratory therapy, and mainly to a respiratory expectoration training device for measuring exhalation pressure and setting vibration frequency. Background Art

[0002] With the changes in modern technology and lifestyle, the air quality has deteriorated, the aging process of the social population has accelerated, and the causes of lung diseases have increased, leading to various chronic lung diseases, such as chronic obstructive pulmonary disease, asthma, emphysema, or some acute lung diseases, such as cough, flu, tracheitis or bronchitis, the airways of some patients will be blocked by sputum; the sputum that cannot be discharged often leads to various lung dysfunctions such as cough, difficulty breathing, and shortness of breath, which seriously reduce the patient's quality of life, weaken the patient's lung function, and increase his susceptibility to bacteria and viruses; when the patient cannot cough up on his own, a sputum suction device is often used to suck it out.

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

[0004] Most of the existing respiratory trainers on the market only have a single exhalation training function, and there is a lack of products that can train both exhalation and inhalation functions. Most of the respiratory trainers on the market use a ball head structure for adjustment, and the ball head is rotated and flushed open during exhalation; insufficient exhalation intensity or an angle deviation during exhalation cannot achieve the training effect, making it inconvenient to expectorate, and users need to use it correctly to achieve the actual effect. Its structure limits the setting of the oscillation frequency, which has a certain impact on the expectoration effect during exhalation air resistance training; a respiratory trainer with an inhalation function can better meet the needs of clinical lung function rehabilitation training; The ball-head structure and seesaw structure of the breathing trainer are difficult to achieve the preset breathing training effect due to the lack of accuracy or the angle deviation 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 normal breathing ability is less cultivated, resulting in a longer respiratory rehabilitation cycle and slow treatment effect. Therefore, in addition to improving exhalation training, it is also necessary to have the function of strengthening inspiratory muscle training in order to adjust the training intensity of inhalation and exhalation, and help patients perform respiratory rehabilitation training more efficiently. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a breathing and expectoration training device for measuring exhalation pressure and setting vibration frequency. The technical problem to be solved is that the pressure component generates downward pressure on the air valve body in the fourth connector, and the pressure is relatively stable; when the exhalation intensity is the largest, the air valve body can be opened, generating a large airflow pressure to form a vibration wave inside the patient's airway, and the airflow pressure is continuously changed by the continuous opening and closing of the air valve, and the vibration causes the sputum in the airway to shift, which is convenient for coughing up the sputum. When the adjustment component rotates, the distance between the upper and lower parts of the pressure component can be adjusted, so that the downward pressure of the valve in the fourth connector is large or small; thereby, the breathing intensity of the patient during breathing training can be adjusted, which is suitable for most moderate and mild pulmonary patients. Breathing training helps cough up sputum. A third one-way valve is set at the third connector for inhalation training, and the inhalation knob can adjust the inhalation volume channel.

The air valve body is used to block or open the air flow channel inside the fourth connector 25, and the middle outer annular surface of the air valve body matches the internal through hole diameter of the fourth connector 25; the pressure component is used to provide the air valve component with a pressing force to press the fourth connector 25 downward, the upper part of the pressure component is arranged in the fourth connector 25, and the lower part of the pressure component is arranged inside the breathing and expectoration device body 10 and directly below the fourth connector 25; the expectoration component is used to provide the air valve component with a maximum stroke for opening upward.

[0036] The upper and lower parts of the pressure component of the present invention are respectively arranged inside and directly below the fourth connecting head 25. The pressure component generates downward pressure on the air valve body in the fourth connecting head 25, and the pressure is relatively stable. The user opens or blocks the air flow channel inside the fourth connecting head 25 during breathing, and the air valve body is able to be opened when the exhalation intensity is maximum. A large airflow pressure is generated to form a vibration wave inside the patient's airway, and the airflow pressure changes continuously through the continuous opening and closing of the air valve. The vibration causes the sputum in the airway to shift, making it easier for the patient to cough out the sputum.

[0037] The fourth connector 25 and the second connector in the middle of the respiratory expectorant body 10 are respectively provided with the upper part and the lower part of the pressure assembly, and the second connector is screwed with an adjustment assembly, which can adjust the distance between the upper part and the lower part of the pressure assembly when it is rotated; the distance between the upper part and the lower part of the pressure assembly is far or close, so that the downward pressure of the valve in the fourth connector 25 is large or small.

[0038] It indirectly adjusts the gas flux through the second connector and the resistance to the opening and closing of the valve of the fourth connector 25, so as to adjust the exhalation intensity of the patient during breathing training. It is suitable for most mild and moderate lung patients in respiratory rehabilitation training and helps to cough up sputum. It provides simulated normal breathing ability training, shortens the treatment cycle, and helps to improve lung function. The respirator is light and compact, making it convenient for patients to carry it with them.

[0039] In this preferred embodiment, the pressure assembly includes a first magnet 42 and a second magnet 33, and the first magnet 42 is arranged inside the fourth connecting head 25; the second connecting head includes a second outer cylinder 31 and a second inner cylinder 32, and the second inner cylinder 32 is coaxially arranged directly below the fourth connecting head 25, and the second inner cylinder 32 radially penetrates and is arranged in the bottom middle part of the respiratory sputum discharger body 10; the second magnet 33 is fixedly arranged at the inner bottom of the second inner cylinder 32, and the second magnet 33 is used to approach the first magnet 42 to generate suction, thereby providing a downward pressure force to the air valve body.

[0040] There is a distance of at least the thickness of the cone head wall between the fourth connector 25 and the second inner tube 32 of the second connector. Even if the blowing direction is slightly skewed, the first magnet 42 and the second magnet 33 can be blown apart. The patient can maintain the minimum breathing volume during the breathing training to prevent breathing obstruction.

[0041] In this preferred embodiment, the sputum removal component includes a vibrator, a left positioning member, and a right positioning member. The bottom of the left positioning member is arranged at the top left end of the respiratory sputum removal device body 10, and the left positioning member is used to install and position the left end of the vibrator; the left end of the right positioning member is arranged at the top right end of the air valve body, and the right positioning member is used to install and position the right end of the vibrator at the left end of the top surface of the air valve body.

[0042] Further, the left positioning member includes a left positioning platform 51, a left buckle block 52, two left guide posts 54, and a left buckle 53. The left positioning platform 51 is horizontally arranged at the top left end of the respiratory sputum discharger body 10; the left end of the left positioning platform 51 is hinged with a left buckle block 52, and the left end of the left buckle block 52 is provided with a left buckle 53. The left buckle block 52 is turned clockwise to buckle the left end of the vibrator on the left positioning platform 51; the two left guide posts 54 are vertically arranged on the top surface of the left positioning platform 51, and the two left guide posts 54 are arranged in the radial direction of the sputum discharger body; Further, the right positioning member includes a right positioning platform, a right buckle block 55, two right guide columns 57, and a right buckle 56. The right positioning platform is horizontally arranged at the right end of the anti-slip plate 43 of the air valve body; the left end of the right positioning platform is hinged with the right buckle block 55, and the bottom of the right buckle 56 is vertically fixedly arranged at the right end of the right buckle block 55. The right buckle block 55 is turned counterclockwise to buckle the right end of the vibrator on the right positioning platform; the two right guide columns 57 are respectively vertically arranged on the left and right sides of the anti-slip plate 43 of the air valve body, and the two left guide columns 54 and the right guide column 57 are both arranged in the radial direction of the sputum discharge body. The right positioning platform is the anti-slip plate 43.

[0043] Furthermore, the vibrating member is a horizontally arranged elastic sheet 58; the height of the left guide column 54 on the left is less than the height of the left guide column 54 on the right, and the height of the right guide column 57 on the right is less than the height of the left guide column 54 on the left; the left end of the elastic sheet 58 is provided with two left guide holes respectively mounted on the two left guide columns 54, and the right end of the elastic sheet 58 is provided with two right guide holes respectively mounted on the two right guide columns 57. Specifically, the longitudinal section of the left buckle block 52 is π-shaped; in another embodiment, the left guide column 54 and the right guide column 57 can be respectively provided with one.

[0044] Furthermore, the materials used for the elastic sheet 58 include but are 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 the patent of the present invention.

[0045] Furthermore, the length of the elastic sheet is 55-65mm, and the vibration frequency of the elastic sheet is 18-38 Hz / second; specifically, the vibration frequency of the elastic sheet is preferably 16-40 Hz, and the swing frequency of 16-40 Hz is beneficial to the directional swinging of bronchial / tracheal cilia to push sputum from small airways to central airways for easy coughing out; in a preferred embodiment, the length of the elastic sheet is 55-65mm, and the vibration frequency of the elastic sheet is 18-38 Hz / second; when the length of the elastic sheet is 70-80mm, the vibration frequency of the elastic sheet is 16-25 Hz / second.

[0046] For elastic sheets of the same material, objects with shorter lengths have smaller strokes and shorter durations for single vibrations, and shorter elastic sheets have higher vibration frequencies. The vibration frequency is adjusted by adjusting the length of the elastic sheet, and the vibration frequency is measured by a vibration frequency tester to achieve the required requirements. The oscillation of bronchial / tracheal cilia is essential for the health of the respiratory system. Cilia block inhaled dust and bacterial impurities through regular up and down swings (swing frequency 16-40 Hz), and expel them from the body, preventing harmful substances from accumulating in the airway, thereby protecting the airway from damage.

[0047] The left and right positioning members are respectively provided at both ends of the air valve body. When the user breathes toward 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 falling out. The pressure assembly includes a first magnet 42 and a second magnet 33. The suction force between the pair of magnets serves as resistance to opening the air valve body by exhalation. The pressure is relatively stable, and the exhalation training effect is good.

[0048] The above vibrating member is designed as an elastic sheet 58, which has a certain elasticity when swinging, so as to adjust the swing angle appropriately and provide appropriate buffering force; the left guide column 54 and the right guide column 57 on the inner side are higher than the outer side, and the left snap-fit ​​block 52 and the right snap-fit ​​block 55 respectively prevent the elastic sheet 58 from being disengaged from the left guide column 54 and the right guide column 57 during the swinging process; the left guide column 54 and the right guide column 57 have good guiding effects. The left end of the elastic sheet 58 and the left guide column 54, and the right end and the right guide column 57 are similar to hinged connections, but the hinge points are not fixed, that is, they slide up and down along the left guide column 54 and the right guide column 57 respectively.

[0049] In this preferred embodiment, the internal through hole of the fourth connecting head 25 is in the shape of a frustum, and the air valve body includes a frustum head 41 and an anti-slip plate 43. The upper and middle parts of the frustum head 41 are in the shape of a frustum, and the lower part is in the shape of a hemisphere. The upper and middle outer walls of the frustum head 41 fit tightly against the inner wall of the through hole of the fourth connecting head 25. The second magnet 33 is movably arranged inside the frustum head 41, and the anti-slip plate 43 is horizontally arranged on the top periphery of the frustum head 41.

[0051] The left part of the outer cover 60 is butted against the left top of the respiratory sputum discharge device body 10, and the right part is clamped against the top of the respiratory sputum discharge device body 10, so the connection is firm and easy to disassemble.

[0052] Preferably, a first one-way valve 22 is disposed inside the first connector 21, and the first one-way valve 22 is connected from bottom to top.

[0053] Example 2, see Figures 3 to 5 On the basis of the first embodiment, an adjusting component is provided on the second connecting head, and the adjusting component is used to rotate and adjust the distance between the adjusting component and the top surface of the second joint, thereby adjusting the distance between the first magnet 42 and the second magnet 33 of the pressure component; the second outer cylinder 31 is sleeved on the outer periphery of the second inner cylinder 32, and the interior of the second outer cylinder 31 passes through and is connected to the interior of the respiratory sputum discharger body.

[0054] The regulating assembly includes a knob cylinder 34, at least one valve plate 38, and at least two valve holes 35. The inner wall of the rotating cylinder is tightly connected to the outer wall of the second outer cylinder 31 through threads; the valve plate 38 is radially arranged at the lower part of the outer ring surface of the second inner cylinder 32, and the valve hole 35 is arranged at the bottom of the rotating cylinder and at the outer periphery of the second inner cylinder 32; the outer diameter of the valve plate 38 is smaller than the inner diameter of the valve hole 35, and the width of the valve plate 38 is not greater than the width of the valve hole 35, and an air flow channel is formed between the valve plate 38 and the valve hole 35; the bottom of the outer ring surface of the second inner cylinder 32 is fixedly connected to the inner bottom of the knob cylinder 34.

[0055] Preferably, a circular valve plate is provided on the upper end surface of the valve hole 35 to block the valve hole 35, thereby increasing the exhalation intensity required to break open a pair of magnets and open the valve body.

[0056] In another embodiment, a circular valve plate is provided on the upper end surface of the valve hole 35 to block the valve hole 35, and the exhalation intensity required to break open a pair of magnets to open the valve body becomes larger.

Several ridges 37 are evenly spaced along the axial direction on the outer ring surface of the rotating cylinder, and the fingertips generate friction with the ridges 37 on the rotating cylinder; it is convenient to accurately adjust the rotation angle, and then adjust the distance between the first magnet 42 and the second magnet 33, and the cutting and staggered area between the valve plate 38 and the valve hole 35.
