Description

Technical Field

[0001] This utility model relates to the field of nebulizer technology, and in particular to a high-efficiency modular nebulizer. Background Technology

[0002] According to Chinese Patent No. CN221845210U, an atomizing eye delivery device is disclosed. This invention uses two separate first and second silicone cover plates to clamp the atomizing plate, covering its perimeter. Based on the elastic deformation of the silicone material and the pressure applied by the cover, a sealed space is formed at the atomizing port. The silicone protects the atomizing plate and forms a sealing structure after compression. The addition of an annular ring further enhances the sealing performance, effectively preventing leakage. Furthermore, the atomizing unit uses magnetic attraction, and by placing the magnet's end face externally, the overall magnetic force is stronger, making it less likely to fall off.

[0003] The aforementioned documents and existing technologies have the following problems: the droplets produced by existing nebulizers during the nebulization process are of varying sizes, large droplets are not easily utilized effectively, leading to drug waste, and it is difficult to ensure the optimal drug delivery distance between the nebulizer nozzle and the eye, reducing the efficiency and accuracy of drug delivery. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient modular nebulizer for drug delivery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency modular nebulizer for drug delivery, comprising a shell, an internal partition, a mounting shell on the surface of the partition, a liquid medicine bottle inside the mounting shell, an output tube at the bottom of the liquid medicine bottle, an atomizing plate inside the output tube, an airflow vortex separator at the end of the output tube, a connecting pipe at the bottom of the airflow vortex separator, a crushing blade inside the connecting pipe, a recovery box at the end of the connecting pipe, a recovery pipe on the surface of the recovery box, a micro pump on the surface of the recovery pipe, a drug delivery tube on the surface of the airflow vortex separator, an atomizing nozzle connected to the surface of the shell, and an infrared sensor on the surface of the shell.

[0006] Preferably, the housing contains a circuit board and a battery.

[0007] Preferably, magnets are provided on both the surface of the partition and the bottom surface of the mounting shell, and contacts are provided on both the surface of the partition and the bottom surface of the mounting shell.

[0008] Preferably, the end of the atomizing nozzle is provided with a fixing ring, and the atomizing nozzle is inserted into the drug delivery tube through the fixing ring.

[0009] Preferably, the mounting shell has an internal mounting plate, and the medicine bottle is magnetically attached to the surface of the mounting plate.

[0010] Preferably, the mounting housing has a support plate inside, and the airflow vortex separator is disposed on the surface of the support plate.

[0011] Preferably, the medicine bottle is connected to the recycling bin via a recycling pipe and a micro pump, and the infrared sensor is electrically connected to the circuit board.

[0012] Beneficial effects

[0013] In this invention, an airflow vortex separator, a recovery box, and a recovery pipe are used. The atomized mixed droplets enter the airflow vortex separator. Under the action of centrifugal force, large droplets are thrown towards the outer wall of the airflow vortex separator and move downward along the outer wall. Finally, they enter the recovery box for storage through the connecting pipe. The micro pump on the recovery pipe is activated to transport the medicine stored in the recovery box back to the medicine bottle for reuse. Small particles, due to their small mass, experience relatively less centrifugal force and are closer to the low-pressure area at the center of the airflow vortex separator. They move upward with the central airflow and are discharged from the drug delivery tube, thereby achieving efficient separation of large and small particles. This effectively avoids drug waste caused by the difficulty in effectively utilizing large droplets, improves drug utilization, reduces usage costs, and ensures that the medicine is fully and rationally used in each nebulization drug delivery process.

[0014] In this invention, an infrared sensor is used to monitor the distance between the nebulizer nozzle and the eye in real time during use and feed the data back to the circuit board. When the drug delivery distance is within the appropriate range, the circuit board will respond quickly and control the device to deliver the drug accurately. Once the distance exceeds this range, the device will intelligently pause the drug delivery operation, effectively preventing poor drug delivery effect or waste that may be caused by improper distance. This not only ensures that each drug delivery is performed at the most suitable distance, but also maximizes the therapeutic effect. Attached Figure Description

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-5A high-efficiency modular nebulizer for drug delivery includes a housing 1. Inside the housing 1 is a circuit board 22, which is the control core, controlling the operation of all components of the device. It receives data from an infrared sensor 4, controls drug delivery according to a preset program, and coordinates the work of each component to ensure stable operation. Inside the housing 1 is a battery 9, which provides power to components requiring electricity, such as the nebulizer plate 16, the micro-pump 14, the infrared sensor 4, and the circuit board 22, maintaining device operation. Inside the housing 1 is a partition 5. Magnets 8 are located on the surface of the partition 5 and the bottom surface of the mounting shell 2. Contacts 6 are also located on the surface of the partition 5 and the bottom surface of the mounting shell 2. The partition 5 rationally divides the internal space of the housing 1, and through the magnets 8 and contacts 6, it connects with the mounting shell 2. The mounting shell 2, when used in conjunction with the partition plate 5, ensures stable installation and electrical connection, facilitating easy disassembly and replacement by personnel, thus achieving modular installation. The mounting shell 2 is located on the surface of the partition plate 5. The mounting shell 2 is used to install and protect internal components such as the liquid medicine bottle 10, the airflow vortex separator 11, and the recovery box 12, providing stable support and protection for these components and ensuring their normal operation during equipment operation. Furthermore, a control module is installed inside the mounting shell 2. The control module is electrically connected to the components inside the mounting shell 2 and electrically connected to the circuit board 22 through the contact 6. After power-on operation, the control module can smoothly issue various instructions to the components inside the mounting shell 2 under the coordination and command of the circuit board 22, thereby ensuring the efficient and orderly operation of the entire nebulization drug delivery process.

[0026] The mounting shell 2 has a mounting plate 20 inside, and the medicine bottle 10 is magnetically attached to the surface of the mounting plate 20. The mounting plate 20 uses magnetic attraction to fix the medicine bottle 10, keeping it stable inside the mounting shell 2 and preventing it from shaking or shifting during use. The medicine bottle 10 inside the mounting shell 2 stores the medicine and serves as a storage container for the drug, providing the necessary drug source for nebulized drug delivery. The bottom of the medicine bottle 10 has an output tube 15, which connects the medicine bottle 10 and the airflow vortex separator 11. After the medicine in the medicine bottle 10 is nebulized, it is delivered to the airflow vortex separator 11. The output tube 15 has an atomizing plate 16 inside, which works based on ultrasonic principles to atomize the medicine. The piezoelectric ceramic material within the atomizing plate 16 generates an inverse piezoelectric effect under the influence of an electric field. Driven by a high-frequency voltage, the piezoelectric ceramic produces mechanical vibrations at the same frequency, typically in the ultrasonic band. This high-frequency vibration is transmitted to the liquid medicine in contact with the atomizing plate 16, generating a strong shear force on the surface of the liquid medicine. Under the action of this high-frequency vibration and shear force, the molecules on the surface of the liquid medicine overcome their own surface tension and are torn into droplets. These droplets are rapidly dispersed into mist droplets under the influence of the surrounding air, thereby realizing the conversion of liquid medicine into gaseous mist droplets and completing the atomization function. The atomizing plate 16 atomizes the liquid medicine in the output tube 15, converting the liquid medicine into a mist droplet state for subsequent separation and administration.

[0027] The mounting housing 2 has a support plate 21 inside, and an airflow vortex separator 11 is set on the surface of the support plate 21. The end of the output pipe 15 is also equipped with an airflow vortex separator 11. The airflow vortex separator 11 uses the principle of centrifugal force to separate the atomized mixed droplets. Large droplets are thrown towards the outer wall of the airflow vortex separator 11 under the action of centrifugal force, move downward along the outer wall, and enter the recovery box 12 through the connecting pipe 17. Small droplets have a small mass and are subjected to less centrifugal force, so they are closer to the low-pressure area in the center of the airflow vortex separator 11 and move upward with the central airflow, and are discharged from the dosing pipe 18, thus achieving effective separation of large and small droplets. The bottom of the airflow vortex separator 11 is equipped with a connecting pipe 17, which connects the airflow vortex separator 11 and the recovery box 12, and transports the separated large droplets to the recovery box 12 for storage, thus achieving the recovery of large droplets. The connecting pipe 17 is equipped with a crushing blade 7, which is installed inside the connecting pipe 17 by a mounting bracket, and the crushing blade 7 is made of a thin sheet. The system is driven by a motor, which is a waterproof, tri-proof motor. When the solid particles of the medicine in the liquid are atomized and sprayed out, the solid particles are separated and fall into the connecting pipe 17. The solid particles are effectively broken by the crushing blade 7 and recovered. They can be atomized into small particles for normal drug administration in the next cycle, reducing drug waste. The end of the connecting pipe 17 is equipped with a recovery box 12, and the surface of the recovery box 12 is equipped with a recovery pipe 13. The surface of the recovery pipe 13 is equipped with a micro pump 14. The medicine bottle 10 is connected to the recovery box 12 through the recovery pipe 13 and the micro pump 14. Under the action of the micro pump 14, the large droplets stored in the recovery box 12 are transported back to the medicine bottle 10 through the recovery pipe 13, realizing the reuse of the medicine. The surface of the airflow vortex separator 11 is equipped with a drug delivery pipe 18. The drug delivery pipe 18 transports the small droplets separated by the airflow vortex separator 11 to the nebulizer nozzle 3, providing a drug channel for eye drug administration. The channel of the drug delivery pipe 18 is relatively short, which facilitates the delivery and discharge of small droplets.

[0028] The surface of the outer shell 1 is connected to an atomizing nozzle 3, which is the outlet for the liquid medication. The end of the atomizing nozzle 3 is provided with a retaining ring 19. The atomizing nozzle 3 is inserted into the administration tube 18 through the retaining ring 19. The atomizing nozzle 3 is inserted into the through hole of the outer shell 1, and the retaining ring 19 at the end of the atomizing nozzle 3 is inserted into the slot at the end of the administration tube 18. The retaining ring 19 and the slot are magnetically connected, thereby achieving a tight connection between the atomizing nozzle 3 and the administration tube 18, preventing liquid medication leakage during administration and ensuring the smooth progress of the administration process. The surface of the outer shell 1 is provided with an infrared sensor 4, which is electrically connected to the circuit board 22. The infrared sensor 4 monitors the distance between the atomizing nozzle 3 and the eye in real time and feeds the data back to the circuit board 22. The circuit board 22 controls the administration operation based on the distance information to ensure that each administration is performed at the most suitable distance, thereby improving the therapeutic effect.

[0029] When using this high-efficiency modular nebulizer, first, the mounting shell 2 is magnetically attached to the outer shell 1. The nebulizer nozzle 3 is then tightly connected to the drug delivery tube 18 via the fixing ring 19. The device is then turned on, and the circuit board 22, acting as the control core, begins operation. The liquid drug in the medicine bottle 10 flows through the output tube 15 to the nebulizer plate 16. The nebulizer plate 16 converts the liquid drug into mixed droplets, which are then transported to the airflow vortex separator 11. Inside the airflow vortex separator 11, large droplets are thrown towards the outer wall of the separator by centrifugal force and move downwards along the outer wall. They then enter the recovery box 12 for storage through the connecting pipe 17. If there are solid particles among the large droplets, they can be effectively broken down by the crushing blade 7. The small droplets are located near the low-pressure zone at the center of the airflow vortex separator 11 and move upward with the central airflow, flowing from the administration tube 18 to the nebulizer 3. During administration, the infrared sensor 4 monitors the distance between the nebulizer 3 and the eye in real time and feeds the data back to the circuit board 22. When the distance is within a suitable range, the circuit board 22 controls the device to administer the medication normally; if the distance is not suitable, the administration stops. The recovery box 12 stores large droplets, and the micro pump 14 on the recovery tube 13 is activated to return the large droplets to the medicine bottle 10 for reuse. After use, the mounting shell 2 can be disassembled for replacement or maintenance as needed using the partition 5 and the magnet 8 and contact 6 on the mounting shell 2. Specific Implementation Example 2:

[0031] A highly efficient modular nebulizer for drug delivery, based on the basic structure in Specific Embodiment 1, further discloses the following: an intelligent display screen can be added to the surface of the outer shell 1 and connected to the circuit board 22. The screen can display the working status of the device in real time, such as the battery level 9, the remaining amount of drug solution, the drug delivery distance, and other information. At the same time, it can also display the device's fault prompts, so that users can understand the device's status in a timely manner and take appropriate action.

[0032] In summary:

[0033] 1. Using an airflow vortex separator 11, a recovery box 12, and a recovery pipe 13, the atomized mixed droplets enter the airflow vortex separator 11. Under the action of centrifugal force, large droplets are thrown towards the outer wall of the airflow vortex separator 11 and move downward along the outer wall. Finally, they enter the recovery box 12 for storage through the connecting pipe 17. The micro pump 14 on the recovery pipe 13 is activated to transfer the medicine stored in the recovery box 12 back to the medicine bottle 10 for reuse. Small particles, due to their small mass, are subjected to relatively small centrifugal force and are closer to the low-pressure area in the center of the airflow vortex separator 11. They move upward with the central airflow and are discharged from the drug delivery pipe 18. This achieves efficient separation of large and small particles, effectively avoiding drug waste caused by large droplets that are difficult to utilize effectively, improving drug utilization, reducing usage costs, and ensuring that the medicine is fully and rationally used in each atomization drug delivery process.

[0034] 2. An infrared sensor 4 is used to monitor the distance between the nebulizer nozzle 3 and the eye in real time during use and feed the data back to the circuit board 22. When the drug delivery distance is within the appropriate range, the circuit board 22 will respond quickly and control the device to deliver the drug accurately. Once the distance exceeds this range, the device will intelligently pause the drug delivery operation, effectively preventing poor drug delivery effect or waste that may be caused by improper distance. This not only ensures that each drug delivery is carried out at the most suitable distance, but also maximizes the therapeutic effect.
