Description

Technical Field

[0001] This invention relates to the field of nebulizer technology, and more particularly to a smart medical nebulizer for drug delivery. Background Technology

[0002] Nebulized inhalation therapy is an important method of drug administration in the treatment of respiratory diseases in newborns. Because newborns cannot sit up independently and have weak neck support, they are usually placed in a supine, lateral, or semi-recumbent position at a large angle during clinical treatment. However, in traditional nebulizers at such angles, the internal medication tends to flow to one side due to gravity, making it difficult to stably cover and enter the suction port. This leads to a series of problems, including interrupted medication intake, unstable nebulization output, excessive medication residue, and inaccurate effective dosage, seriously affecting treatment efficacy and causing drug waste.

[0003] To address the issue of medication pooling when tilted, patent publication number CN120037520B discloses a neonatal nebulizer, comprising a bottle, a balancing mechanism, a delivery mechanism, a vibration mechanism, and a nebulizing mechanism. The balancing mechanism includes a storage hopper, a first conical tube, and a balancing component; the delivery mechanism includes an air inlet pipe and a connecting component; and the vibration mechanism includes a fan and a vibrating component. This invention patent, through a complex mechanical balancing mechanism, ensures that the internal medicine cup remains relatively vertical when the external shell is tilted, thus guaranteeing that the suction port at the bottom of the cup is always immersed in the medication. However, several problems remain: its mechanical oscillation structure is complex, with many moving parts, posing risks of jamming and wear, resulting in low reliability over long-term use; to improve the smoothness of the oscillation disc within the oscillation chamber, a small amount of gas may leak between the oscillation disc and the oscillation chamber, making complete sealing difficult; the overall structure is complex, making cleaning and disinfection inconvenient and prone to creating unsanitary corners. Therefore, a smart medication delivery medical nebulizer is proposed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art and to propose an intelligent medical nebulizer for drug delivery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart medical nebulizer for drug delivery includes a bottle body, an nebulizing tube connected to one side of the bottle body, a bottom partition fixed to the bottom inner side of the bottle body, and further includes: The cap assembly is detachably attached to the top of the bottle. The atomizing and sieving assembly includes an inner cone tube, baffles, a reflux baffle, and a screening block.

The inclined plate is fixed to the bottom of the liquid storage chamber, and the slide rod slides in cooperation with the inclined plate. One end of the slide rod is movably connected to the insertion tube through a connecting plate, and the other end passes through the bottle body and is fixed to the pressing head.

[0009] Preferably, in the self-driven vibration unit, the pneumatic actuator includes a rectangular tube, an air float, a spring, an inclined block, a second slide rod, and a baffle; the top of the rectangular tube is connected to the insertion tube, the rectangular tube is located between the flexible tube and the outer conical tube, the air float is slidably disposed in the rectangular tube, the spring acts on the air float to provide a restoring force, the inclined block is fixedly connected to the air float, the second slide rod cooperates with the inclined surface of the inclined block, the baffle is fixedly connected to one side of the second slide rod and slidably disposed in the rectangular tube, and the mechanical vibration unit is a top rod fixedly connected to the top of the air float.

[0012] Preferably, the top of the liquid storage chamber is provided with an openable and closable flip cover.

[0013] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes the principle of gravity to ensure that the liquid medicine can naturally converge and be stably extracted at any tilt angle, eliminating the need for a complex swing sealing mechanism. The air flotation block is driven by the negative pressure of the inner cone tube liquid channel, and a mechanical negative feedback mechanism is formed by the inclined block, slide bar II, baffle and spring linked to it.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Reference Figure 1 - Figure 7 A smart medical nebulizer for drug delivery includes a bottle body 1, an nebulizing tube 2 connected to one side of the bottle body 1, and a bottom partition 13 fixed to the bottom inner side of the bottle body 1. It also includes: The cap assembly is detachably attached to the top of the bottle body 1; The atomizing and sieving assembly includes an inner cone tube 17, a baffle plate 21, a reflux baffle 11 and a screening block 9. An isolated air passage 24 is formed inside the inner cone tube 17. The reflux baffle 11 is composed of an inclined plate and a flat plate, and has insertion holes 25 on its edge. The liquid return unit includes a liquid storage chamber 14, a plug pipe 15, an outer conical tube 16 located at the bottom of the return baffle 11, a liquid channel 23 inside the outer conical tube 16, a flexible tube 18, and a connecting hole 25 and a plug-in return pipe 12. The self-driven vibration unit includes a pneumatic actuator and a mechanical vibration unit connected to the liquid channel 23; the pneumatic actuator can periodically operate in response to the negative pressure change in the liquid channel 23 and drive the mechanical vibration unit to generate periodic impacts on the return baffle 11. The liquid storage chamber 14 is located on the side of the outer conical tube 16 away from the atomizing tube 2 and is fixedly connected to the bottom partition 13. One side of the chamber is connected to the liquid injection tube 6, which passes through the bottle body 1. The top of the liquid injection tube 6 is fixedly connected to the liquid injection hole 5.

[0019] In this embodiment, the atomizer's outlet pipe is connected to the bottom of the inner cone tube 17, and the liquid medicine is injected into the storage chamber 14 through the injection pipe 6 and injection hole 5. When the atomizer is started, compressed gas flows through the air passage 24 of the inner cone tube 17 and is ejected at high speed. According to Bernoulli's principle, the high-speed airflow forms a stable negative pressure zone at the inlet of the adjacent liquid passage 23. This negative pressure continuously draws the liquid medicine from the storage chamber 14 into the liquid passage 23 through the insertion pipe 15. The liquid medicine is sheared by the high-speed airflow and sprayed onto the front baffle 21, achieving initial atomization.

[0020] The mixture of medication generated by the impact baffle 21 undergoes inertial separation at the inclined surface of the return baffle 11 under the impingement of the subsequent airflow. Smaller, qualified droplets, with less inertia, can follow the main airflow along the inclined surface of the return baffle 11, bypassing the screening block 9, and ultimately being output for inhalation through the nebulizer tube 2 facing the user's face. Larger droplets, with greater inertia, cannot smoothly change direction with the airflow and thus impact and remain on the return baffle 11. Because the nebulizer tube 2 needs to face the user's face, it is oriented at an angle, flowing through the inclined design of the conical cover 10 and into the inlet 25.

[0021] The cover assembly includes a snap-fit ​​cover 4, an adjustable top cover 3, a fixed top cover 7, and a central connecting column 8. The adjustable top cover 3 is rotatably connected to the top of the snap-fit ​​cover 4, the fixed top cover 7 is fixedly connected to the bottom of the snap-fit ​​cover 4, the central connecting column 8 is fixedly connected to the bottom of the fixed top cover 7, the inner cone tube 17 is fixedly connected to the center of the bottom partition 13, the screening block 9 is fixedly connected to the outer wall of the central connecting column 8 and connected to the return partition 11 through the cone cover 10, and the baffle 21 is fixed to the lower center of the return partition 11 through the mounting base 22. In the liquid return unit, one end of the insertion tube 15 can be inserted into or detached from the outer conical tube 16, and the return tube 12 is fixedly connected to the bottle body 1 and the bottom partition 13. The insertion tube 15 is connected to a sliding unlocking mechanism, which includes a slide rod 19, a pressing head 20 and an inclined plate 26. The inclined plate 26 is fixed to the bottom of the liquid storage chamber 14. The slide rod 19 is slidably engaged with the inclined plate 26. One end of the slide rod 19 is movably connected to the insertion tube 15 through the connecting plate 33, and the other end passes through the bottle body 1 and is fixed to the pressing head 20.

[0022] In this embodiment, the collected liquid medicine flows back to the insertion tube 15 area through the return tube 12 and the flexible tube 18. This area is always within the negative pressure range of the inlet of the liquid channel 23, so the returned liquid medicine is automatically re-inhaled and enters the next atomization cycle. This process significantly improves the utilization rate of the liquid medicine and the uniformity of the atomized particles.

[0023] Among them, the pneumatic actuator in the self-driven vibration unit includes a rectangular tube 29, an air float 34, a spring 28, an inclined block 30, a slide rod 31, and a baffle 35; the rectangular tube 29 is connected to the top of the insertion tube 15, the rectangular tube 29 is located between the flexible tube 18 and the outer conical tube 16, the air float 34 is slidably disposed in the rectangular tube 29, the spring 28 acts on the air float 34 to provide a restoring force, the inclined block 30 is fixedly connected to the air float 34, the slide rod 31 cooperates with the inclined surface of the inclined block 30, the baffle 35 is fixedly connected to one side of the slide rod 31 and slidably disposed in the rectangular tube 29, and the mechanical vibration unit is a top rod 27 fixedly connected to the top of the air float 34; The self-driven vibration unit is mounted on one side of the liquid storage chamber 14 via the mounting bracket 32.

[0024] In this embodiment, the same negative pressure source used for liquid absorption acts simultaneously on the upper surface of the air flotation block 34, generating a downward adsorption force that causes it to overcome the elastic force of the spring 28 and begin to move downward. As the air flotation block 34 moves downward, the inclined block 30 at its bottom drives the sliding rod 31 to move laterally, causing the baffle 35 to move into the channel of the rectangular tube 29, gradually reducing the cross-sectional area of ​​the airflow channel. As the channel narrows, the airflow resistance increases, resulting in a corresponding weakening of the negative pressure suction force acting on the air flotation block 34. When the suction force weakens to the point where it cannot balance the restoring force of the spring 28, the air flotation block 34 is quickly pushed back upward. At the instant the air flotation block 34 moves upward, the top rod 27 at its top strikes the bottom of the return baffle 11 upward, generating a high-frequency micro-amplitude vibration. This vibration effectively peels off and accelerates the flow of liquid droplets adhering to the inclined surface of the return baffle 11 towards the insertion hole 25. After the air flotation block 34 resets, the airflow channel recovers, and the negative pressure suction force once again adsorbs and moves it downward, starting the next cycle. The process operates autonomously and periodically, intelligently optimizing recycling efficiency.

[0025] The top of the liquid storage chamber 14 is equipped with an openable and closable flip cover.

[0026] In this embodiment, pulling the pressing head 20 and the slide bar 19 outwards separates the insertion tube 15 from the outer cone tube 16. Then, pulling out the snap-fit ​​cover 4 upwards allows all components integrated on the central connecting column 8 to be removed as a whole. Both the liquid storage chamber 14, which can be opened, can be directly rinsed with water.

[0027] After cleaning, align the insertion tube 15 with the return tube 12 and insert it back in. Push back the pressing head 20 to lock and reset. The injection tube 6 can be used as a convenient handle during disassembly and assembly.

[0028] Working principle: The air outlet pipe of the nebulizer is connected to the bottom of the inner cone tube 17. The liquid medicine is injected into the storage chamber 14 through the injection pipe 6 and the injection hole 5. When the nebulizer is started, the compressed gas flows through the air passage 24 of the inner cone tube 17 and is ejected at high speed. According to Bernoulli's principle, the high-speed airflow forms a stable negative pressure zone at the inlet of the adjacent liquid passage 23. This negative pressure continuously draws the liquid medicine in the storage chamber 14 into the liquid passage 23 through the insertion pipe 15. The liquid medicine is sheared by the high-speed airflow and sprayed onto the baffle 21 in front, achieving initial nebulization.

[0029] The mixture of medication generated by the impact baffle 21 undergoes inertial separation at the inclined surface of the return baffle 11 under the impingement of the subsequent airflow. Smaller, qualified droplets, with less inertia, can follow the main airflow along the inclined surface of the return baffle 11, bypassing the screening block 9, and ultimately being output for inhalation through the nebulizer tube 2 facing the user's face. Larger droplets, with greater inertia, cannot smoothly change direction with the airflow and thus impact and remain on the return baffle 11. Because the nebulizer tube 2 needs to face the user's face, it is oriented at an angle, flowing through the inclined design of the conical cover 10 and into the inlet 25.

[0030] The collected liquid medicine flows back to the insertion tube 15 area through the return tube 12 and the flexible tube 18. This area is always within the negative pressure range of the inlet of the liquid channel 23, so the returned liquid medicine is automatically re-inhaled and enters the next atomization cycle. This process significantly improves the utilization rate of the liquid medicine and the uniformity of the atomized particles.

[0031] The same negative pressure source used for liquid suction acts simultaneously on the upper surface of the air flotation block 34, generating a downward suction force that causes it to overcome the elastic force of the spring 28 and begin to move downward. As the air flotation block 34 moves downward, the sliding rod 31 is driven to move laterally by the inclined block 30 at its bottom, which in turn moves the baffle 35 into the channel of the rectangular tube 29, gradually reducing the cross-sectional area of ​​the airflow channel. As the channel narrows, the airflow resistance increases, resulting in a corresponding weakening of the negative pressure suction force acting on the air flotation block 34. When the suction force weakens to the point that it cannot balance the restoring force of the spring 28, the air flotation block 34 is quickly pushed back upward. At the instant the air flotation block 34 moves upward, the top rod 27 at its top pushes upward against the bottom of the return baffle 11, generating a high-frequency micro-amplitude vibration. This vibration can effectively peel off and accelerate the flow of droplets attached to the inclined surface of the return baffle 11 towards the insertion hole 25. After the air flotation block 34 resets, the airflow channel is restored, and the negative pressure suction force once again suctions it downward, starting the next cycle. The process operates autonomously and periodically, intelligently optimizing recycling efficiency.

[0032] Pull the pressing head 20 and the slide bar 19 outward to separate the insertion tube 15 from the outer cone tube 16. Then pull the snap cover 4 upward to remove all the components integrated on the central connecting column 8. Both the liquid storage chamber 14 and the top cover can be rinsed directly with water.

[0033] After cleaning, align the insertion tube 15 with the return tube 12 and insert it back in. Push back the pressing head 20 to lock and reset. The injection tube 6 can be used as a convenient handle during disassembly and assembly.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
