Description

Technical Field

[0001] This invention relates to the field of nebulization technology in respiratory medicine, specifically to a nebulization device for respiratory medicine. Background Technology

[0002] Nebulization refers to the process of breaking down a liquid into tiny droplets through a nozzle or high-speed airflow. In the medical field, nebulization specifically refers to converting medication into tiny particles so that they can directly reach the lungs through the respiratory tract. The principle of nebulization is to use the high-speed airflow generated by a nebulizer or the high-speed airflow of an oxygenation device to impact the liquid medication and form it into a mist, i.e., tiny particles. These tiny drug particles reach the respiratory tract and lungs through the body's natural breathing, thereby producing the corresponding therapeutic effect on the target organs. Medical nebulization is widely used in the treatment of respiratory diseases, such as bronchial asthma, chronic obstructive pulmonary disease (COPD), acute respiratory infections, and allergic cough. In addition, nebulization therapy is also an effective way to administer medication to patients who cannot normally receive oral treatment, such as children or the elderly.

[0003] Medical nebulizers are primarily used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity. Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. A nebulizer atomizes medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving a painless, rapid, and effective treatment.

[0004] In the use of existing medical devices, patients need to hold the nebulizer cup and put the nebulized medicine into their mouths to achieve the purpose of nebulization therapy. However, in actual use, patients may put down the nebulizer cup due to coughing or other reasons. At this time, there will still be nebulized medicine produced in the nebulizer cup, but since the patient will not inhale the nebulized medicine, it will further lead to waste of nebulized medicine.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention controls whether the nebulized medication flows out of the outlet by using the opening and closing of the first baffle. When the patient holds the outer surface of the cup shell, the patient is nebulizing normally. By opening the two baffles, the patient's normal nebulization is not hindered. When the patient does not hold the outer surface of the cup shell, the patient may pause nebulization due to coughing or other reasons and put down the cup shell, causing the two baffles to close automatically, further preventing the nebulized medication from flowing out of the outlet, thereby reducing the waste of medication when the patient temporarily stops nebulizing.

[0017] 2. The present invention, when the nebulizer is used again after the two baffles are closed, causes the rectangular plate to swing around the rotation axis three, thereby dispersing the medicine at the outlet. This prevents the medicine from being irritated by the high concentration at the outlet when the nebulizer is used again after the two baffles are closed, thus reducing the patient's discomfort.

[0018] 3. This invention uses a folding rod to strike the concave plate, causing the cup shell to vibrate, accelerating the fall of the drug droplets, reducing the phenomenon of drug sticking to the inner wall of the cup shell, and further allowing a large number of drug droplets adhering to the inner wall of the cup shell to slide into the concave plate in time. This allows the water absorption groove to draw the liquid medicine in the concave plate into the cavity, making atomization smooth and further reducing the waste of atomizing agent.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1 to 12 This embodiment provides a technical solution: a nebulizer for respiratory medicine, including a cup shell 1, a drug outlet 6 fixedly connected to the surface of the cup shell 1, a handle 11 fixedly connected to the outer surface of the cup shell 1, a nebulizing component provided inside the cup shell 1, a drug inlet 9 fixedly connected to the upper surface of the cover plate 10, a dust cover 8 snapped onto the upper end face of the drug inlet 9, a connecting rod 27 fixedly connected to the lower end face of the air cylinder 18, the lower surface of the connecting rod 27 fixedly connected to the surface of the conical sleeve 26, and an air groove is provided on the lower end face of the air cylinder 18, a groove is provided inside the lower part of the conical sleeve 26, and a ventilation tube 24 is fixedly connected to the groove wall. The atomizing components include: The concave plate 19, conical block 41, and conical sleeve 26 are connected together. The outer surface of the concave plate 19 is fixedly connected to the inner wall of the cup shell 1. The lower end face of the concave plate 41 is fixedly connected to the surface of the concave plate 19, and the surface of the conical block 41 is slidably connected to the inner wall of the conical sleeve 26. The inner wall of the connecting pipe 12 is slidably connected to the outer surface of the vent pipe 24. The other end of the connecting pipe 12 is connected to a compressor. The inner wall of the conical sleeve 26 is provided with a water absorption groove 25. The inner wall of the tip of the conical sleeve 26 is also provided with a cavity that communicates with the water absorption groove 25. The surface of the cavity is provided with a through vent groove 28, which is located below the vent groove 26.

[0023] More specifically, in this embodiment: during use, medication is added to the concave plate 19 inside the cup shell 1 through the medication inlet 9, and then the lower end of the ventilation tube 24 is connected to the connecting tube 12. Then, the other end of the connecting tube 12 is connected to the compressor. Then, a mouthpiece is installed at the medication outlet 6. The patient puts the mouthpiece in their mouth and then starts the compressor. The compressed air enters the cavity at the top of the conical sleeve 26 through the connecting tube 12 and is then sprayed out through the ventilation groove 28. Through the high-speed airflow in the connecting tube 12, the liquid medication in the concave plate 19 is drawn into the cavity through the water absorption groove 25. Then, the high-speed airflow is used to spray out through the ventilation groove 28, which drives the medication to be sprayed onto the guide plate 29, thus turning it into atomized liquid medication. Then, through the guide plate 26, the atomized liquid medication flows into the medication outlet 6 and is inhaled by the patient. The modular design of this atomizing component, with its detachable connecting tube 12 and cup shell 1, makes the atomizing device more modular. This allows for the replacement of atomizing parts during use, reducing the possibility of infection during atomization and further improving the safety of the atomizing device during use.

[0024] It is worth noting that this embodiment also includes: a flow rate regulation component comprising: The system includes a baffle 14, a cover 10, an air cylinder 18, and a dustproof net 23. The lower end face of the cover 10 is fixedly connected to the upper end face of the cup shell 1, and the lower end face of the cover 10 is fixedly connected to the upper end face of the air cylinder 18. The inner wall of the air cylinder 18 is fixedly connected to the side of the dustproof net 23. The side of the baffle 14 is fixedly connected to the inner wall of the air cylinder 18. The upper end face of the baffle 14 has a through-hole adjustment groove 1. The upper end face of the baffle 14 is fixedly connected to a rotating shaft 15. The surface of the rotating shaft 15 is rotatably connected to a baffle 23. The upper end face of the baffle 23 has a through-hole adjustment groove 2. The upper end face of the baffle 23 is fixedly connected to a lever 7. The lower end face of the air cylinder 18 is fixedly connected to a guide plate 29. The outer surface of the air cylinder 18 is also fixedly connected to a guide plate 26.

[0025] More specifically, in this embodiment: by rotating the lever 7, the second baffle 13 is driven to rotate on the first baffle 14, thereby changing the overlap range between the first and second adjustment grooves, further changing the opening between the air cylinders 18, thereby adjusting the airflow difference between the cup shell 1 and the connecting pipe 12. When the overlap range between the first and second adjustment grooves is larger, the amount of atomized medicine sprayed is larger; when the overlap range between the first and second adjustment grooves is smaller, the amount of atomized medicine sprayed is smaller. The flow rate adjustment component is designed to change the overlap between adjustment tank 1 and adjustment tank 2, thereby altering the airflow difference between the adjustment cup shell 1 and the connecting pipe 12, and further adjusting the amount of atomized drug sprayed. This allows the atomizing device to adjust the atomized drug according to actual conditions, further improving the practicality of the atomizing device.

[0026] Example 2, based on the above examples: Please see Figures 1 to 12 In this embodiment, a blocking component is included, comprising: The cup shell consists of a baffle plate 50, a rotating rod 49, and a curved rod 46. The end face of the rotating rod 49 is fixedly connected to the inner wall of the cup shell 1. The end face of the curved rod 46 has a through groove, and the groove wall is rotatably connected to the surface of the rotating rod 49. The surface of the baffle plate 50 is fixedly connected to the surface of the curved rod 46. The end face of the baffle plate 50 has a sliding groove, and a sliding column 51 is slidably connected to the surface of the sliding groove. A curved rod 47 is fixedly connected to the end surface of the sliding column 51. The other end of the curved rod 47 slidably penetrates the inner wall of the cup shell 1. A connecting block 48 is hinged to the end of the curved rod 47 away from the sliding column 51. A gripping piece 2 is fixedly connected to the surface of the connecting block 48. A spring piece 3 is fixedly connected to the surface of the gripping piece 2. The surface of the spring piece 3 is also fixedly connected to the outer surface of the cup shell 1.

[0027] More specifically, in this embodiment: during use, since the patient needs to hold the nebulizer, the patient needs to grip the outer surface of the cup shell 1, which will generate a certain gripping force on the cup shell 1, and then squeeze the spring plate 3. At the same time, the gripping plate 2 moves closer to the cup shell 1. During the movement of the gripping plate 2, the crank rod 47 will move into the cup shell 1, thereby causing the sliding column 51 to slide in the sliding groove. This further causes the crank rod 46 to rotate around the rotating rod 49 as an axis, and further causes the two baffles 50 to move away from each other, so that the nebulized drug flows out from the outlet 6. When the patient does not hold the cup shell 1, under the action of the spring plate 3, the gripping plate 2 moves away from the cup shell 1, further causing the two baffles 50 to close together, preventing the nebulized drug from flowing out from the outlet 6. The blocking component is designed to control whether the nebulized medication flows out of the outlet 6 by opening and closing the baffles 50. When the patient holds the outer surface of the cup shell 1, the patient is nebulizing normally. By opening the two baffles 50, the patient's normal nebulization is not blocked. When the patient does not hold the outer surface of the cup shell 1, the patient may pause nebulization due to coughing or other reasons and put down the cup shell 1, causing the two baffles 50 to close automatically, further preventing the nebulized medication from flowing out of the outlet 6, thereby reducing the waste of medication when the patient temporarily stops nebulizing.

[0028] Example 3, based on the above examples: Please see Figures 1 to 12 In this embodiment, a buffer component is included, comprising: The rotating rod 32, the vent pipe 5, and the airbag 4 are connected by a through slot on the surface of the cup shell 1. The wall of the slot is fixedly connected to the surface of the vent pipe 5. The other end of the vent pipe 5 is fixedly connected to the surface of the airbag 4. The end surface of the rotating rod 32 is rotatably connected to a fixing plate 34. The lower end face of the fixing plate 34 is fixedly connected to the upper end face of the guide plate 29. The surface of the rotating rod 32 is rotatably connected to a cylindrical shell 33. The outer surface of the cylindrical shell 33 is fixedly connected to the surface of the fixing plate 34. The surface of the rotating rod 32 is also fixedly connected to a toggle piece 31. The surface of the toggle piece 31 is slidably connected to the inner wall of the cylindrical shell 33. One end of the vent pipe 5 is fixedly connected to the interior of the cylindrical shell 33. The surface of the cylindrical shell 33 is also fixedly connected to a vent pipe 30.

[0029] More specifically, in this embodiment: after the two baffles 50 are closed, the connecting pipe 12 will continue to inflate the cup shell 1. However, since there is no outlet in the cup shell 1 after the baffles 50 are closed, the air pressure in the cup shell 1 will continue to rise. The rising air pressure will enter the cylindrical shell 33 through the vent pipe 30, and then push the actuating plate 31 to drive the rotating rod 32 to rotate. It will then be injected into the airbag 4 through the vent pipe 5 to reduce the air pressure in the cup shell 1. This buffer assembly is designed to use the airbag 4 to buffer the rising air pressure inside the cup after the two baffles 50 are closed, further preventing the cup from being damaged by high pressure inside.

[0030] Example 4, based on the above examples: Please see Figures 1 to 12 In this embodiment, a concentration reduction component is included, comprising: The system comprises a fixed frame 42, a cam 40, a crank rod 38, and a connecting rod 25. The cam 40 has a through hole at its center end, the surface of which is fixedly connected to the end surface of the rotating rod 22. The eccentric end of the cam 40 is fixedly connected to one end of the crank rod 38, and the other end of the crank rod 38 is fixedly connected to the surface of the connecting rod 25. The outer surface of the fixed frame 42 is fixedly connected to the upper surface of the guide plate 29. The inner wall of the fixed frame 42 is slidably connected to the surface of the connecting rod 25. A sliding frame 36 is also slidably connected to the surface of the connecting rod 25. A rectangular plate 45 is fixedly connected to the outer surface of the sliding frame 36. A rotating shaft 34 is fixedly connected to the side of the rectangular plate 45. A fixed plate 43 is rotatably connected to the surface of the rotating shaft 344. The lower end surface of the fixed plate 43 is fixedly connected to the upper end surface of the guide plate 29.

[0031] More specifically, in this embodiment: after the two baffles 50 are closed, the gripping plate 2 is moved by hand to open the two baffles 50. The pressure inside the cup shell 1 will decrease rapidly, thus depressurizing the airbag 4. The gas inside the airbag 4 will flow into the cup shell 1 through the ventilation tube 5, further pushing the actuating plate 31, causing the rotating rod 32 to rotate in the opposite direction, thereby driving the cam 40 to rotate. Then, the crank rod 38 drives the connecting rod 35 to slide in the fixed frame 42, and at the same time, the connecting rod 35 slides in the sliding frame 36, causing the rectangular plate 45 to swing about the rotating shaft 44, thereby dispersing the medicine at the drug outlet 6. This prevents the drug concentration at the drug outlet 6 from being too high and irritating the patient when the nebulizer is used again after the two baffles 50 are closed, thus reducing the patient's discomfort. The concentration reduction component is designed so that when the nebulizer is used again after the two baffles 50 are closed, the rectangular plate 45 swings around the rotating shaft 44, thereby dispersing the medicine at the drug outlet 6. This prevents the drug concentration at the drug outlet 6 from being too high and irritating the patient when the nebulizer is used again after the two baffles 50 are closed, thus reducing the patient's discomfort.

[0032] Example 5, based on the above examples: Please see Figures 1 to 12 In this embodiment, it includes: a wall-attachment lowering component, which includes: The structure consists of a folding rod 22, a second fixing plate 53, a second rotating shaft 21, and a third fixing plate 17. The side of the second fixing plate 53 is fixedly connected to the inner wall of the cup shell 1. A through longitudinal groove 20 is provided on the upper end face of the second fixing plate 53. The second rotating shaft 21 is fixedly connected to the groove wall of the longitudinal groove 20. The lower end face of the third fixing plate 17 is fixedly connected to the upper end face of the second fixing plate 53. A through rotating groove is provided on the surface of the folding rod 22. The groove wall of the rotating groove is rotatably connected to the surface of the second rotating shaft 21. A sliding column 22 is fixedly connected to the end face of the folding rod 22 above the second fixing plate 53. An arc-shaped sliding frame 39 is slidably connected to the surface of the sliding column 22. The outer surface of the arc-shaped sliding frame 39 is fixedly connected to the upper surface of the third fixing plate 17. A spring 37 is fixedly connected to the inner wall of the arc-shaped sliding frame 39. The other end of the spring 37 abuts against the surface of the sliding column 22.

[0033] More specifically, in this embodiment: during the nebulization process, a large number of drug droplets will adhere to the inner wall of the cup shell 1. In the later stage of nebulization, because the large number of drug droplets attached to the inner wall of the cup shell 1 cannot slide into the concave plate 19 in time, the water absorption groove 25 cannot smoothly draw the liquid medicine in the concave plate 19 into the cavity, which further leads to the problem of uneven nebulization in the later stage of nebulization. In the later stage of nebulization, the patient squeezes the folding rod 22 with both hands, which further causes the sliding column 2 52 to slide in the arc sliding frame 39, thereby squeezing the spring 1 37. When the folding rod 22 is released, under the action of the spring 1 37, the folding rod 22 will return to its original position, thereby knocking the concave plate 19, causing the cup shell 1 to vibrate, accelerating the fall of drug droplets, and reducing the phenomenon of drug sticking to the inner wall of the cup shell 1. The wall-mounting and lowering component is designed so that the cup shell 1 vibrates by striking the concave plate 19 with the folding rod 22, which accelerates the fall of the drug droplets and reduces the phenomenon of drug sticking to the inner wall of the cup shell 1. Furthermore, it allows a large number of drug droplets attached to the inner wall of the cup shell 1 to slide into the concave plate 19 in time, so that the water absorption tank 25 can draw the drug liquid in the concave plate 19 into the cavity, making the atomization smooth and further reducing the waste of atomizing agent.

[0034] Working principle: When using this nebulizer for respiratory medicine, the following steps are performed: Medication is added to the concave plate 19 inside the cup shell 1 through the inlet 9. Then, the lower end of the ventilation tube 24 is connected to the connecting tube 12, and the other end of the connecting tube 12 is connected to the compressor. A mouthpiece is then installed at the outlet 6. The patient places the mouthpiece in their mouth, and the compressor is started. Compressed air enters the cavity at the top of the conical sleeve 26 through the connecting tube 12, and is then ejected through the ventilation groove 28. The high-speed airflow in the connecting tube 12 draws the medication from the concave plate 19 into the cavity through the suction groove 25, and then the high-speed airflow ejects it through the ventilation groove 28, spraying the medication onto the guide plate 29. The solution is atomized into a liquid medication, which then flows into the outlet 6 via guide plate 2 16 and is inhaled by the patient. By rotating the lever 7, the baffle 2 13 rotates on the baffle 1 14, thereby changing the overlap between the adjusting groove 1 and the adjusting groove 2, further changing the opening between the air cylinder 18, thus adjusting the airflow difference between the cup shell 1 and the connecting pipe 12, and further adjusting the amount of atomized liquid medication sprayed. During use, since the patient needs to hold the nebulizer, the patient needs to grip the outer surface of the cup shell 1, which will generate a certain gripping force on the cup shell 1, which will squeeze the spring plate 1 3 and simultaneously cause the gripping plate 2 to move closer to the cup shell 1. During the movement of the gripping plate 2, the crank rod 2 47 will be driven. The movement of the sliding column 51 into the cup shell 1 causes the crank rod 46 to rotate around the rotating rod 49, further displacing the two baffles 50 and allowing the nebulized medication to flow out from the outlet 6. When the patient does not hold the cup shell 1, the grip plate 2 moves away from the cup shell 1 under the action of the spring plate 3, further closing the two baffles 50 and preventing the nebulized medication from flowing out of the outlet 6. After the two baffles 50 close, the connecting tube 12 continues to inflate the cup shell 1. However, because there is no outlet after the baffles 50 close, the air pressure inside the cup shell 1 continuously rises, causing the air pressure inside the cup to increase. The pressure enters the cylindrical shell 33 through the vent pipe 30, then pushes the actuating plate 31 to rotate the rotating rod 32. Further pressure is injected into the airbag 4 through the vent pipe 5 to reduce the air pressure inside the cup shell 1. After the two baffles 50 close, the gripping plate 2 is moved by hand, causing the two baffles 50 to open. The pressure inside the cup shell 1 decreases rapidly, thus depressurizing the airbag 4. The gas inside the airbag 4 flows into the cup shell 1 through the vent pipe 5, further pushing the actuating plate 31, causing the rotating rod 32 to rotate in the opposite direction, thereby rotating the cam 40. Then, the crank rod 38 drives the connecting rod 35 to slide within the fixed frame 42, and simultaneously allows the connecting rod 35 to slide within the sliding frame 36.The rectangular plate 45 oscillates around the rotating axis 44, thus dispersing the medication at the dispensing port 6. In the later stages of nebulization, the patient's two hands squeeze the lever 22, further causing the sliding column 52 to slide within the arc-shaped sliding frame 39, thereby compressing the spring 37. When the lever 22 is released, the spring 37 causes it to return to its original position, striking the concave plate 19 and causing the cup shell 1 to vibrate, accelerating the fall of the medication droplets and reducing the adhesion to the inner wall of the cup shell 1.
