Description

Technical Field

[0001] The invention relates to the technical field of breathing training devices, and in particular to a breathing training device for patients with chronic obstructive pulmonary disease. Background Art

[0002] COPD is a common chronic disease characterized by chronic bronchitis and / or emphysema with airflow obstruction, which can further develop into cor pulmonale and respiratory failure. It is related to abnormal inflammatory response to harmful gases and particles, with high disability and mortality rates. The global incidence rate of people over 40 years old is as high as 9% to 10%. COPD is a common preventable and treatable disease characterized by persistent airflow limitation. The progressive development of airflow limitation is related to the enhanced chronic inflammatory response of the airways and lungs to toxic particles or gases.

[0003] In the process of treating patients with chronic obstructive pulmonary disease, a breathing training device is one of the indispensable devices. Most of the breathing training devices on the market cannot help clear the nasal cavity and relieve breathing resistance to make breathing smoother, and are not fully suitable for specific groups of people. Therefore, a breathing training device for patients with chronic obstructive pulmonary disease is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a breathing training device for patients with chronic obstructive pulmonary disease.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A breathing training device for patients with chronic obstructive pulmonary disease comprises a training unit and a mouth suction unit. The mouth suction unit is clamped in the middle of the training unit. The training unit comprises an adjustment mechanism and a nasal suction mechanism vertically inserted in the inner cavity of the adjustment mechanism. A deformation mechanism is arranged at the front end of the adjustment mechanism, and the mouth suction unit is laterally inserted in the inner cavity of the deformation mechanism.

[0006] Preferably, the nasal suction mechanism includes an assembly tube and a ventilation groove opened in the inner cavity of the assembly tube, the inner cavity wall of the ventilation groove is provided with an extrusion mechanism, a nasal suction piece is laterally arranged at the top position of the rear end surface of the assembly tube, an air inlet is arranged at the edge position of the nasal suction piece, and the air inlet is connected with the inner cavity of the ventilation groove. The user holds the two ends of the mounting piece in one hand, fits the entire device to the user's face, fits the rear of the nasal suction piece to the philtrum of the user, and makes the two sets of air inlets respectively align with the nostrils of the user. When the user inhales, the airflow in the inner cavity of the ventilation groove is directly absorbed.

[0007] Preferably, the squeezing mechanism includes a pushing block and a reinforcing block installed between the two groups of pushing blocks. A deformable expansion ball is installed between the combination of the two groups of pushing blocks and the reinforcing blocks arranged up and down. The reinforcing blocks that fit the two ends of the deformable expansion ball are squeezed against each other by the reinforcing block. Since the deformable expansion ball can expand and contract, the deformable expansion ball is in a continuous contraction state after being subjected to pressure. It can quickly squeeze the gas in the space adjacent to the two groups of pushing blocks and the inner cavity wall of the ventilation groove. At this time, negative pressure is generated in the internal space, and the gas will be absorbed into the above-mentioned internal space by the bottom of the ventilation groove. The gas in this internal space moves along the outer surface of the structure of the pushing block, the reinforcing block and the deformable expansion ball. The narrow space formed therein will effectively block the passing airflow. At this time, the airflow is inhaled by the user from the air inlet In the nasal cavity, due to the obstruction of airflow by the narrow space of the device, the airflow entering the nasal cavity will have a higher speed. This fast-flowing airflow brings a cool feeling, stimulates the nasal mucosa, and passes through the flow path in the narrow space. It has a certain filtering effect on the particulate matter in the air, reducing the probability of inhaling impurities or particles, thereby improving the quality of inhaled air. The suction force and airflow movement generated by negative pressure stimulate the flow of nasal secretions, help clear blockages, and improve nasal patency. Due to the stimulation of the mucosa by the airflow when passing through the nasal cavity, it has a slight massage effect, stimulating the sensory nerves of the nasal cavity, and bringing an effect similar to soothing or awakening. If the user has nasal congestion or difficulty breathing, this device helps clear the nasal cavity through the negative pressure inhalation mechanism, relieves breathing resistance, and makes breathing smoother.

[0008] Preferably, the nasal inhalation mechanism also includes a mixing mechanism covering the top position of the ventilation groove, the mixing mechanism includes an assembly horizontal bar installed laterally in the middle position of the inner cavity wall of the ventilation groove and a grid installed on the end faces of both sides of the assembly horizontal bar, and the surface of the grid is arranged and distributed with an adapter assembly. When the mixing mechanism covers the top of the ventilation groove, gas can enter through the gap between the adapter assembly and the grid, and the entering gas will contact the auxiliary medicine liquid preset in the adapter assembly, and the gas will carry the auxiliary medicine liquid into the nasal cavity of the user, the auxiliary medicine liquid is salbutamol, and salbutamol is a short-acting beta receptor agonist. The two can relieve wheezing symptoms during acute exacerbation by inhalation of the drugs through atomization, wherein the gas is in full contact with the salbutamol auxiliary medicine liquid, thereby realizing precise control of medicine liquid atomization and gas mixing, and improving the treatment effect. The atomized salbutamol directly enters the nasal cavity with the gas, effectively reducing drug waste and enhancing the local effect of the drug in the airway and lungs.

[0009] Preferably, the adjustment mechanism includes a mounting frame and a push plate vertically arranged at the interval between two groups of mounting frames, adjacent push plates are connected by springs, mounting parts are inserted on both sides of the rear end surface of the mounting frame, and the inner cavity of the mounting part has a built-in groove.

[0010] Preferably, the assembly tube is vertically inserted into the inner cavity of the built-in groove, so that the nasal suction mechanism and the adjustment mechanism are combined into a whole, and an external motor is connected at the interval between the two sets of mounting parts, and the rearmost push piece is pushed laterally by the external motor. At this time, the push piece will move along the inner cavity wall of the two sets of mounting frames, and the springs set between the intervals will increase the flexibility between the push pieces during the movement, so that the push pieces are more stable during the movement, thereby avoiding discomfort or damage caused by structural rigidity. Because the rear end face of the reinforcement is fixedly connected to the mounting part through a connecting cross bar, but the bracket, movable rod and reinforcement are movably connected, the movable connection design between the bracket, movable rod and reinforcement makes the device have higher flexibility during dynamic operation, avoids wear or fatigue caused by rigid connection, and improves the durability and reliability of the device; The deformation mechanism includes a bracket and an inserted cross bar inserted between two groups of vertically arranged brackets, the inserted cross bar is horizontally inserted into the top of the ear block, the lower end surface of the ear block is connected to the connecting piece through the connecting block, and the bottom of the connecting piece is connected to the outer end surface of the mounting outer ring.

[0011] Preferably, the deformation mechanism further comprises a movable rod connected to the outer end surface of the top of the bracket, the other end of the movable rod is connected to the reinforcement, the other end of the reinforcement is connected to the rear end surface of the connection block, and the rear end surface of the reinforcement is connected in series with the front end surface of the mounting member through a connecting cross bar; When the push piece is pushed forward, the position where the bracket contacts it will move forward synchronously. At this time, the insertion cross bar, ear block, connection block and connection piece drive the installation outer ring to adjust the angle, so that the inclination angle of the mouth suction unit installed on the inner cavity wall of the installation outer ring can be fine-tuned, so as to adapt to different oral shapes and user needs, improve the adaptability and comfort of the device, and the synergistic effect of the insertion cross bar, ear block, connection block and connection piece makes the angle adjustment process more precise, which can achieve rapid response to different needs and enhance the practicality and versatility of the device. Through the lateral propulsion of the motor and the linkage of multiple components, automated and convenient operation is achieved, the complexity of manual adjustment is reduced, and the convenience and experience of the user process are improved. The angle fine-tuning function expands the use scenarios of the device and can adapt to a wider range of oral forms and needs, especially in medical treatment, nursing or specific populations such as children or the elderly. It has significant advantages.

[0012] Preferably, the mouth inhalation unit includes an inhalation cylinder and inner support rods installed in an annular array on the inner cavity wall of the inhalation cylinder, built-in rods are arranged on the side end faces of the inner support rods, and the other ends of each group of built-in rods converge on the outer end face of the inner inhalation tube, and the inner inhalation tube is arranged in the middle position of the inner cavity of the inhalation cylinder, and six groups of combined structures formed by the inner support rods and built-in rods arranged in an annular array on the inner cavity wall of the inhalation cylinder are connected to the outer end wall of the inner inhalation tube in the middle, surrounding the outer end wall of the inner inhalation tube, providing strong connection and support, ensuring that the device is stable and not easy to deform during use, and when the gas passes through the inner cavity of the mouth inhalation unit, the airflow will touch the structural outer surfaces of the inner support rods and the built-in rods, and the outer surface design of the inner support rods and the built-in rods enables the airflow to be reasonably distributed inside the device, reduces turbulence, ensures the smoothness of gas exchange, and provides stable breathing support for the user.

[0013] A small portion of the gas will be directly exchanged with the outside world through the inner intake tube, providing an auxiliary channel for the overall airflow, further improving air flow efficiency and comfort. An interface for connecting to an external air filter is designed at the inner intake tube, allowing for filtering of particulate matter, harmful gases or pathogens in special environments, thereby improving the quality of inhaled air.

[0014] A micro-spiral texture structure is added to the outer surface of the inner support rod and the built-in rod. The design of the micro-spiral texture can optimize the gas flow characteristics, reduce energy loss, and promote more gas to enter the device evenly, thereby improving the overall gas exchange performance of the device. It can also reduce turbulence through precise flow guidance and further optimize the airflow path, thereby improving gas exchange efficiency.

[0015] A hydrophobic coating is added to the outer surface of the inner support rod and the built-in rod. The hydrophobic coating gives the outer surface of the inner support rod and the built-in rod good waterproof properties, effectively preventing water vapor, liquid or moisture from adhering to the surface, reducing airflow blockage or pollution caused by moisture accumulation, thereby forming a stable and smooth airflow. Combined with the hydrophobic coating to prevent moisture interference, it provides users with a more refreshing and clean breathing experience, which is particularly suitable for high humidity environments. The hydrophobic coating reduces the adhesion of pollutants on the surface of the device, such as dust, bacteria or moisture accumulation, making the device easier to clean while extending its service life.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. It realizes precise control of drug liquid atomization and gas mixing, improves the treatment effect, and the atomized salbutamol enters the nasal cavity directly with the gas, effectively reducing drug waste and enhancing the local effect of the drug in the airway and lungs.

[0017] 2. Due to the obstruction of airflow by the narrow space of the device, the airflow entering the nasal cavity will have a higher speed. This fast-flowing airflow brings a cool feeling, stimulates the nasal mucosa, and passes through the flow path in a narrow space. It has a certain filtering effect on the particulate matter in the air, reducing the probability of inhaling impurities or particles, thereby improving the quality of inhaled air. The suction force and airflow movement generated by negative pressure stimulate the flow of nasal secretions, help clear blockages, and improve nasal patency. Due to the stimulation of the mucosa by the airflow when passing through the nasal cavity, it has a slight massage effect, stimulating the sensory nerves of the nasal cavity, and bringing an effect similar to soothing or awakening. If the user has nasal congestion or difficulty breathing, this device helps clear the nasal cavity through the negative pressure inhalation mechanism, relieves breathing resistance, and makes breathing smoother.

[0018] 3. Connect an external motor at the interval between the two sets of mounting parts, and use the external motor to push the rearmost push piece horizontally. At this time, the push piece will move along the inner cavity wall of the two sets of mounting frames, and the springs set between the intervals will increase the flexibility of the push pieces, making the push pieces more stable during movement, thereby avoiding discomfort or damage caused by structural rigidity. Because the rear end face of the reinforcement is fixedly connected to the mounting part through the connecting cross bar, but the bracket, movable rod and reinforcement are movably connected, the movable connection design between the bracket, movable rod and reinforcement makes the device more flexible during dynamic operation, avoids wear or fatigue caused by rigid connection, and improves the durability and reliability of the device.

[0019] 4. The synergistic effect of the insertion cross bar, ear block, connecting block and connecting piece makes the angle adjustment process more precise, which can achieve rapid response to different needs and enhance the practicality and versatility of the device. Through the lateral push of the motor and the linkage of multiple components, automatic and convenient operation is achieved, which reduces the complexity of manual adjustment and improves the convenience and experience of the user's use process. The angle fine-tuning function expands the use scenarios of the device and can adapt to a wider range of oral forms and needs, especially in medical treatment, nursing or specific populations such as children or the elderly. It has significant advantages.

[0020] 5. Ensure that the device is stable and not easily deformed during use. When the gas passes through the inner cavity of the mouth-suction unit, the airflow will touch the outer surface of the structure of the inner support rod and the built-in rod. The outer surface design of the inner support rod and the built-in rod enables the airflow to be reasonably distributed inside the device, reducing turbulence, ensuring smooth gas exchange, and providing stable breathing support for users.

[0021] 6. A small part of the gas will be directly exchanged with the outside world through the inner inhalation tube, providing an auxiliary channel for the overall airflow, further improving the air flow efficiency and comfort of use. An interface for connecting to an external air filter device is designed at the inner inhalation tube, allowing particulate matter, harmful gases or pathogens to be filtered in special environments, thereby improving the quality of inhaled air.

[0022] 7. Add a micro-spiral texture structure to the outer surface of the inner support rod and the built-in rod. The design of the micro-spiral texture can optimize the gas flow characteristics, reduce energy loss, and promote more gas to enter the device evenly, thereby improving the overall gas exchange performance of the device. It can reduce turbulence through precise flow guidance and further optimize the airflow path, thereby improving gas exchange efficiency.

[0023] 8. Add a hydrophobic coating to the outer surface of the inner support rod and the built-in rod. The hydrophobic coating gives the outer surface of the inner support rod and the built-in rod good waterproof performance, effectively preventing water vapor, liquid or moisture from adhering to the surface, reducing airflow blockage or pollution caused by moisture accumulation, thereby forming a stable and smooth airflow. Combined with the hydrophobic coating to prevent moisture interference, it provides users with a more refreshing and clean breathing experience, which is especially suitable for high humidity environments. The hydrophobic coating reduces the adhesion of pollutants on the surface of the device, such as dust, bacteria or moisture accumulation, making the device easier to clean while extending its service life.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The nasal suction mechanism 12 includes an assembly tube 121 and a ventilation groove 122 opened in the inner cavity of the assembly tube 121, an extrusion mechanism 123 is arranged on the inner cavity wall of the ventilation groove 122, a nasal suction piece 125 is arranged horizontally at the top position of the rear end surface of the assembly tube 121, and an air inlet 126 is arranged at the edge position of the nasal suction piece 125, and the air inlet 126 is connected with the inner cavity of the ventilation groove 122. The user holds the two ends of the mounting piece 114 in one hand, fits the whole device to the face of the user, and fits the rear of the nasal suction piece 125 to the philtrum of the user, so that the two groups of air inlet 126 are respectively aligned with the nostrils of the user, and when the user inhales, the airflow in the inner cavity of the ventilation groove 122 is directly absorbed.

[0029] In the second embodiment, the squeezing mechanism 123 comprises a pushing block 1231 and a reinforcing block 1232 installed between the two groups of pushing blocks 1231. A deformable expansion ball 1233 is installed between the combination of the two groups of pushing blocks 1231 and the reinforcing block 1232 arranged up and down. The reinforcing blocks 1232 which are attached to the two ends of the deformable expansion ball 1233 are mutually squeezed by the reinforcing block 1232. Since the deformable expansion ball 1233 can expand and contract, the deformable expansion ball 1233 is in a continuous contraction state after being subjected to pressure. It can quickly squeeze the gas in the space adjacent to the inner cavity wall of the two groups of pushing blocks 1231 and the ventilation groove 122. At this time, negative pressure is generated in the internal space, and the gas is absorbed into the above-mentioned internal space by the bottom of the ventilation groove 122. The gas in this internal space moves along the outer surface of the structure of the pushing block 1231, the reinforcing block 1232 and the deformable expansion ball 1233 as a path, and the narrow space formed therein The space will effectively block the passing airflow, and at this time the airflow is inhaled into the nasal cavity by the user at the air inlet 126. Due to the blocking of the airflow by the narrow space of the device, the airflow entering the nasal cavity will have a higher speed. This fast-flowing airflow brings a cool feeling, stimulates the nasal mucosa, and passes through the flow path in the narrow space. It has a certain filtering effect on the particulate matter in the air, reduces the probability of inhaling impurities or particles, and thus improves the quality of inhaled air. The suction force and airflow movement generated by the negative pressure stimulate the flow of nasal secretions, help clear blockages, and improve nasal patency. Due to the stimulation of the mucosa by the airflow when passing through the nasal cavity, this has a slight massage effect, stimulating the sensory nerves of the nasal cavity, and bringing about an effect similar to relaxation or wakefulness. If the user has nasal congestion or difficulty breathing, this device helps clear the nasal cavity through the negative pressure inhalation mechanism, relieves breathing resistance, and thus makes breathing smoother.

[0030] Embodiment 3, the nasal suction mechanism 12 also includes a mixing mechanism 124 covering the top position of the ventilation groove 122, the mixing mechanism 124 includes an assembly bar 1241 installed transversely at the middle position of the inner cavity wall of the ventilation groove 122 and a grid 1242 installed on the end faces of both sides of the assembly bar 1241, and the surface of the grid 1242 is arranged and distributed with an adapter assembly 1243. When the mixing mechanism 124 covers the top of the ventilation groove 122, the gas can enter through the gap between the adapter assembly 1243 and the grid 1242, and the gas entering will be mixed with The gas will come into contact with the auxiliary liquid medicine preset in the adapter assembly 1243, and the auxiliary liquid medicine will be carried by the gas into the nasal cavity of the user. The auxiliary liquid medicine is salbutamol, which is a short-acting β2 receptor agonist. The two medicines inhaled through atomization can relieve the wheezing symptoms during the acute exacerbation period. The gas is in full contact with the salbutamol auxiliary liquid medicine, and the precise control of the liquid medicine atomization and gas mixing is achieved, thereby improving the treatment effect. The atomized salbutamol directly enters the nasal cavity with the gas, which effectively reduces the waste of medicine and enhances the local effect of the medicine in the airway and lungs.

[0031] Embodiment 4, the adjustment mechanism 11 includes a mounting frame 111 and a push piece 112 vertically arranged at the interval between two groups of mounting frames 111, adjacent push pieces 112 are connected by springs 113, mounting parts 114 are inserted on both sides of the rear end surface of the mounting frame 111, and the inner cavity of the mounting part 114 is provided with a built-in groove 115.

[0032] The assembly cylinder 121 is vertically inserted into the inner cavity of the built-in groove 115, so that the nasal suction mechanism 12 and the adjustment mechanism 11 are combined into a whole. An external motor is connected at the interval between the two sets of mounting parts 114, and the rearmost push piece 112 is pushed horizontally by the external motor. At this time, the push piece 112 will move along the inner cavity wall of the two sets of mounting frames 111 as a path, and the spring 113 set between the intervals will increase the flexibility between the push pieces 112 during the movement, so that the push piece 112 is more stable during the movement, thereby avoiding discomfort or damage caused by structural rigidity. Because the rear end face of the reinforcement 138 is fixedly connected to the mounting part 114 through the connecting cross bar 139, but the bracket 131, the movable rod 137 and the reinforcement 138 are movably connected, the movable connection design between the bracket 131, the movable rod 137 and the reinforcement 138 makes the device have higher flexibility during dynamic operation, avoids wear or fatigue caused by rigid connection, and improves the durability and reliability of the device; Embodiment 5, the deformation mechanism 13 includes a bracket 131 and an inserted cross bar 132 inserted between two groups of vertically arranged brackets 131, the inserted cross bar 132 is horizontally inserted into the top of the ear block 133, the lower end surface of the ear block 133 is connected to the connecting piece 135 through the connecting block 134, and the bottom of the connecting piece 135 is connected to the outer end surface of the mounting outer ring 136.

[0033] The deformation mechanism 13 further includes a movable rod 137 connected to the outer end surface of the top of the bracket 131, the other end of the movable rod 137 is connected to the reinforcing member 138, the other end of the reinforcing member 138 is connected to the rear end surface of the connecting block 134, and the rear end surface of the reinforcing member 138 is connected in series with the front end surface of the mounting member 114 through the connecting cross bar 139. When the push piece 112 is pushed forward, the position where the bracket 131 contacts it will move forward synchronously. At this time, the cooperation of the insertion cross bar 132, the ear block 133, the connection block 134 and the connecting piece 135 drives the installation outer ring 136 to adjust the angle, so that the inclination angle of the mouth suction unit 2 installed on the inner cavity wall of the installation outer ring 136 can be finely adjusted, so as to adapt to different oral shapes and user needs, improve the adaptability and comfort of the device, and the synergistic effect of the insertion cross bar 132, the ear block 133, the connection block 134 and the connecting piece 135 makes the angle adjustment process more precise, which can achieve a quick response to different needs and enhance the practicality and versatility of the device. Through the lateral propulsion of the motor and the linkage of multiple components, automated and convenient operation is achieved, the complexity of manual adjustment is reduced, and the convenience and experience of the user process are improved. The angle fine-tuning function expands the use scenarios of the device and can adapt to a wider range of oral forms and needs, especially in medical treatment, nursing or specific populations such as children or the elderly. It has significant advantages.

[0034] In Example 6, the mouth inhalation unit 2 includes an inhalation cylinder 21 and an inner support rod 22 installed in a circular array on the inner cavity wall of the inhalation cylinder 21, and built-in rods 23 are arranged on the side end face of the inner support rod 22. The other end of each group of built-in rods 23 converges on the outer end face of the inhalation inner tube 24, and the inhalation inner tube 24 is arranged in the middle position of the inner cavity of the inhalation cylinder 21. The six groups of combined structures formed by the inner support rods 22 and the built-in rods 23 arranged in a circular array on the inner cavity wall of the inhalation cylinder 21 are connected to the outer end wall of the inhalation inner tube 24 in the middle, and surround the outer end wall of the inhalation inner tube 24 to provide a strong connection and support, ensuring that the device is stable and not easy to deform during use, and when the gas passes through the inner cavity of the mouth inhalation unit 2, the airflow will touch the structural outer surfaces of the inner support rods 22 and the built-in rods 23. The outer surface design of the inner support rods 22 and the built-in rods 23 enables the airflow to be reasonably distributed inside the device, reduces turbulence, ensures the smoothness of gas exchange, and provides stable breathing support for the user.

[0035] In Example 7, a small portion of the gas will be directly exchanged with the outside world through the inner air intake tube 24, providing an auxiliary channel for the overall airflow, further improving the air flow efficiency and comfort of use. An interface for connecting to an external air filter device is designed at the inner air intake tube 24, allowing particulate matter, harmful gases or pathogens to be filtered in special environments, thereby improving the quality of the inhaled air.

[0036] Embodiment 8 adds a micro-spiral texture structure to the outer surface of the inner support rod 22 and the built-in rod 23. The design of the micro-spiral texture can optimize the gas flow characteristics, reduce energy loss, promote more gas to enter the device evenly, improve the overall gas exchange performance of the device, reduce turbulence through precise flow guidance, further optimize the airflow path, and improve gas exchange efficiency.

[0037] Embodiment 9, a hydrophobic coating is added to the outer surface of the inner support rod 22 and the built-in rod 23. The hydrophobic coating gives the outer surface of the inner support rod 22 and the built-in rod 23 good waterproof properties, effectively preventing water vapor, liquid or moisture from adhering to the surface, reducing airflow blockage or pollution caused by moisture accumulation, thereby forming a stable and smooth airflow, combined with the hydrophobic coating to prevent moisture interference, providing users with a more refreshing and clean breathing experience, which is particularly suitable for high humidity environments. The hydrophobic coating reduces the adhesion of pollutants on the surface of the device, such as dust, bacteria or moisture accumulation, making the device easier to clean while extending its service life.

[0038] In summary: a breathing training device for patients with chronic obstructive pulmonary disease comprises a training unit 1 and an oral suction unit 2, the oral suction unit 2 is sandwiched in the middle of the training unit 1, the training unit 1 comprises an adjustment mechanism 11 and a nasal suction mechanism 12 vertically inserted in the inner cavity of the adjustment mechanism 11, a deformation mechanism 13 is arranged at the front end of the adjustment mechanism 11, and the inner cavity of the deformation mechanism 13 is laterally inserted with the oral suction unit 2, the user holds the two ends of the mounting member 114 in one hand, fits the whole device to the user's face, fits the rear of the nasal suction member 125 to the user's philtrum, and makes the two groups of inhalation ports 126 respectively align with the user's nostrils, and when the user inhales, the airflow in the inner cavity of the ventilation groove 122 is directly absorbed; When the mixing mechanism 124 covers the top of the ventilation groove 122, the gas can enter through the gap between the provided adapter assembly 1243 and the grid 1242, and the entering gas will contact the auxiliary liquid medicine preset in the adapter assembly 1243, and the gas will carry the auxiliary liquid medicine into the nasal cavity of the user, the auxiliary liquid medicine is salbutamol, and salbutamol is a short-acting β2 receptor agonist. The two drugs inhaled by atomization can relieve the wheezing symptoms in the acute exacerbation period, wherein the gas is fully in contact with the salbutamol auxiliary liquid medicine, and the precise control of the liquid medicine atomization and gas mixing is realized, and the treatment effect is improved. The atomized salbutamol directly enters the nasal cavity with the gas, which effectively reduces the waste of medicine and enhances the local effect of the medicine in the airway and lungs; The reinforcing blocks 1232 at both ends of the deformable expansion ball 1233 are squeezed against each other by the reinforcing blocks 1232. Since the deformable expansion ball 1233 can expand and contract, the deformable expansion ball 1233 is in a state of continuous contraction after being subjected to pressure, and can quickly squeeze the gas in the space adjacent to the inner cavity wall of the two groups of pushing blocks 1231 and the ventilation groove 122. At this time, negative pressure is generated in the internal space, and the gas will be absorbed into the above-mentioned internal space by the bottom of the ventilation groove 122. The gas in this internal space moves along the outer surface of the structure of the pushing block 1231, the reinforcing block 1232 and the deformable expansion ball 1233. The narrow space formed therein will effectively block the airflow passing through. At this time, the airflow is inhaled into the nasal cavity by the user at the air inlet 126. The airflow entering the nasal cavity will have a higher speed due to the obstruction of the airflow in a narrow space. This fast-flowing airflow brings a cool feeling, stimulates the nasal mucosa, and has a certain filtering effect on the particulate matter in the air through the flow path in a narrow space, reducing the probability of inhaling impurities or particles, thereby improving the quality of inhaled air. The suction force and airflow movement generated by negative pressure stimulate the flow of nasal secretions, help clear blockages, and improve nasal patency. Due to the stimulation of the mucosa by the airflow when passing through the nasal cavity, it has a slight massage effect, stimulating the sensory nerves of the nasal cavity, and bringing a similar effect of soothing or awakening. If the user has a stuffy nose or difficulty breathing, this device helps clear the nasal cavity through the negative pressure inhalation mechanism, relieves breathing resistance, and makes breathing smoother; An external motor is connected at the interval between the two groups of mounting parts 114, and the external motor is used to push the rearmost push piece 112 laterally. At this time, the push piece 112 will move along the inner cavity wall of the two groups of mounting frames 111, and the springs 113 set between the intervals will increase the flexibility of the push piece 112, so that the push piece 112 is more stable during the movement, thereby avoiding discomfort or damage caused by structural rigidity. Because the rear end face of the reinforcement 138 is fixedly connected to the mounting part 114 through the connecting cross bar 139, but the bracket 131, the movable rod 137 and the reinforcement 138 are movably connected, the movable connection design between the bracket 131, the movable rod 137 and the reinforcement 138 makes the device have higher flexibility during dynamic operation, avoids wear or fatigue caused by rigid connection, and improves the durability and reliability of the device; When the push piece 112 is pushed forward, the position where the bracket 131 contacts it will move forward synchronously. At this time, the cooperation of the insertion cross bar 132, the ear block 133, the connection block 134 and the connecting piece 135 drives the installation outer ring 136 to adjust the angle, so that the inclination angle of the mouth suction unit 2 installed on the inner cavity wall of the installation outer ring 136 can be finely adjusted, so as to adapt to different oral shapes and user needs, improve the adaptability and comfort of the device, and the synergistic effect of the insertion cross bar 132, the ear block 133, the connection block 134 and the connecting piece 135 makes the angle adjustment process more precise, which can achieve a quick response to different needs and enhance the practicality and versatility of the device. Through the lateral push of the motor and the linkage of multiple components, the automatic and convenient operation is realized, the complexity of manual adjustment is reduced, and the convenience and experience of the user's use process are improved. The angle fine-tuning function expands the use scenarios of the device and can adapt to a wider range of oral forms and needs, especially in medical treatment, nursing or specific groups such as children or the elderly. The six groups of combined structures formed by the inner support rods 22 and the built-in rods 23 arranged in a circular array on the inner cavity wall of the suction cylinder 21 are connected to the outer end wall of the suction inner tube 24 in the middle, and surround the outer end wall of the suction inner tube 24, providing a strong connection and support, ensuring that the device is stable and not easy to deform during use, and when the gas passes through the inner cavity of the mouth suction unit 2, the airflow will touch the outer surface of the structure of the inner support rods 22 and the built-in rods 23. The outer surface design of the inner support rods 22 and the built-in rods 23 makes the airflow reasonably distributed inside the device, reduces turbulence, ensures the smoothness of gas exchange, and provides stable breathing support for users; A small part of the gas will be directly exchanged with the outside world through the inner inhalation tube 24, providing an auxiliary channel for the overall airflow, further improving the air flow efficiency and user comfort. An interface for connecting an external air filter device is designed at the inner inhalation tube 24, allowing particulate matter, harmful gases or pathogens to be filtered in special environments, thereby improving the quality of the inhaled air. A micro-spiral texture structure is added to the outer surface of the inner support rod 22 and the inner rod 23. The design of the micro-spiral texture can optimize the gas flow characteristics, reduce energy loss, and promote more gas to enter the device evenly, thereby improving the overall gas exchange performance of the device, reducing turbulence through precise flow guidance and further optimizing the airflow path, thereby improving the gas exchange efficiency; A hydrophobic coating is added to the outer surface of the inner support rod 22 and the built-in rod 23. The hydrophobic coating gives the outer surface of the inner support rod 22 and the built-in rod 23 good waterproof properties, effectively preventing water vapor, liquid or moisture from adhering to the surface, reducing airflow blockage or pollution caused by moisture accumulation, thereby forming a stable and smooth airflow. Combined with the hydrophobic coating to prevent moisture interference, it provides users with a more refreshing and clean breathing experience, which is particularly suitable for high humidity environments. The hydrophobic coating reduces the adhesion of pollutants on the surface of the device, such as dust, bacteria or moisture accumulation, making the device easier to clean while extending its service life.
