Description

Technical Field

[0001] This application relates to the field of ophthalmic medical device technology, and more particularly to a nebulizer for treating eye patients. Background Technology

[0002] Ophthalmic nebulizers primarily use atomization technology to transform liquid medications or nutrients into tiny droplets that act directly on the ocular surface and surrounding tissues. This increases tear secretion, stabilizes the tear film, and relieves dryness, foreign body sensation, and burning pain. During nebulization treatment of the patient's eyes using a pneumatic nebulizer, the high-pressure airflow output from the nebulizer is sprayed into the nebulization cup through a connecting tube, breaking the nebulized liquid in the cup into droplets. The droplets are then transported through a delivery tube to a transparent eye mask, which the patient wears over their head to cover their eyes for nebulization treatment.

[0003] During the operation of a pneumatic nebulizer, the piston reciprocating frequency is the decisive factor affecting the nebulization effect and nebulization duration. If the piston reciprocating frequency is too high, the amount of compressed air per unit time is large, the airflow velocity is fast, and the pressure is too strong. The droplets formed by impacting the nebulizing liquid are prone to collision and aggregation, forming large droplets on the inner wall of the transparent eye mask and the surface of the patient's eye skin. These large droplets not only cause discomfort to the patient, but also affect the contact area between the droplets and the patient's eye skin, reducing drug utilization and nebulization effect. However, if the piston reciprocating frequency is too low, it will not only lead to insufficient compressed air per unit time, but also slow airflow velocity, weak pressure, and poor stability, resulting in a significant decrease in the nebulization efficiency of the nebulizer cup, a significant increase in nebulization time, and an increased burden on the patient's tolerance. It will also prevent the nebulizing liquid from being fully dispersed, resulting in droplet size that is too coarse and does not meet the requirements of nebulization therapy, which will also affect drug utilization and nebulization effect. Summary of the Invention

[0004] This application proposes a nebulization device for treating eye patients, which slows down the formation rate of droplets inside the transparent eye mask, reduces the probability of reduced contact area between droplets and skin due to droplets adhering to the patient's eye skin surface, ensures that droplets can continuously and evenly adhere to the eye surface to exert their efficacy, thereby guaranteeing the nebulization effect, improving the utilization rate of the nebulized liquid, and ensuring nebulization efficiency without causing excessively long nebulization treatment time. This allows patients to complete the nebulization treatment within a comfortable and tolerable time, thus solving the problem that when patients use nebulizers for eye nebulization, the unadjustable nebulization efficiency leads to droplet formation on the patient's eye skin or excessively long nebulization time, affecting drug utilization and nebulization effect.

[0005] To achieve the above objectives, this application adopts the following technical solution: a nebulizer for treating eye patients, comprising a nebulizer body, an nebulizing cup fixedly installed on the outside of the nebulizer body, the nebulizing cup being fixedly connected to the air outlet of the nebulizer body, the nebulizing cup being fixedly connected to a transparent eye mask via a delivery tube, and a dual-axis motor fixedly installed inside the nebulizer body, the output end of the dual-axis motor being fixedly connected to a main shaft, electromagnets being symmetrically fixedly installed at both ends of the main shaft, transmission plates being symmetrically slidably installed on the outer sides of the two electromagnets, and the transmission plates being made of ferromagnetic material; two air pumps being fixedly installed on the inner bottom wall of the nebulizer body, and the two air pumps being respectively adapted to the corresponding transmission plates; piston rods being slidably installed on the top of the air pumps; and the two... The transmission plate has two symmetrically connected transmission wheels on its outer sides. A connecting shaft is fixedly installed on the side of the transmission wheel away from the transmission plate. The end of the connecting shaft away from the transmission wheel is rotatably connected to the piston connecting rod. The axis of the connecting shaft does not coincide with the axis of the transmission wheel, and the distance between the two connecting shafts and the corresponding axis of the transmission wheel is different. A liquid level sensor is fixedly installed inside the atomizing cup, and the liquid level sensor is electrically connected to the controller inside the atomizer body. During the operation of the atomizer body, when the liquid level of the atomized liquid in the atomizing cup is lower than the liquid level sensor, the liquid level sensor sends a signal to the controller. The controller then outputs a control signal to turn the power supply on and off to the two electromagnets, thereby completing the start and stop between the two piston connecting rods and changing the atomization speed of the atomized liquid.

[0006] Furthermore, two main hydraulic cylinders are symmetrically fixedly installed on the side of the electromagnet near the transmission plate. The main hydraulic cylinders are airtightly slidably connected to a main piston. A main piston rod is fixedly installed on the side of the main piston near the transmission plate, and the end of the main piston rod away from the main piston moves through the side wall of the main piston and is fixedly connected to the transmission plate. When the electromagnet is energized and generates an attraction force on the transmission plate, the transmission plate drives the main piston to slide synchronously through the main piston rod.

[0007] Furthermore, a main spring is fitted on the outer side of the main piston rod, and the two ends of the main spring are fixedly connected to the side wall of the main piston and the inner side wall of the main hydraulic cylinder, respectively. The spring force of the main spring provides limiting support for the transmission plate when the transmission plate is not attracted by the electromagnet.

[0008] Furthermore, a secondary rotating shaft is fixedly installed on the side of the transmission wheel away from the connecting shaft, and a secondary hydraulic cylinder is fixedly connected to the end of the main piston away from the transmission plate. A secondary piston is airtightly slidably connected inside the secondary hydraulic cylinder, and a secondary piston rod is fixedly connected to the end of the secondary piston away from the main hydraulic cylinder. The end of the secondary piston rod away from the secondary piston moves through the side wall of the secondary hydraulic cylinder and is rotatably mounted with a ball. Two slots are symmetrically opened on the outer side of the secondary rotating shaft, and the two slots are respectively engaged or disengaged from the corresponding balls.

[0009] Furthermore, the main hydraulic cylinder and the rodless chamber of the auxiliary hydraulic cylinder are both filled with hydraulic medium. The outer side of the main hydraulic cylinder is fixedly connected to a connecting pipe for the hydraulic medium to flow between the rod chamber and the rodless chamber of the main hydraulic cylinder. When the transmission plate drives the main piston to slide synchronously through the main piston rod, the hydraulic medium flows through the connecting pipe and the limiting ring to assist the auxiliary piston rod and the ball in engaging and disengaging from the slot.

[0010] Furthermore, a secondary spring is fitted on the outer side of the secondary piston rod, and the two ends of the secondary spring are fixedly connected to the side wall of the secondary piston and the inner side wall of the secondary hydraulic cylinder, respectively, so that the elastic force of the secondary spring assists the secondary piston rod in resetting and sliding.

[0011] Furthermore, two support rods are symmetrically fixedly installed on the side of the electromagnet near the transmission plate. The end of the support rod away from the electromagnet is fixedly connected to the corresponding main hydraulic cylinder to provide support and limit for the main hydraulic cylinder.

[0012] Furthermore, a one-way air inlet pipe is fixedly connected to the side of the air pump, and the ends of the two air inlets away from the air pump are fixedly connected to the air inlet on the atomizer body through a three-way pipe. A one-way air outlet pipe is also fixedly connected to the side of the air pump, and the ends of the two air outlet pipes away from the air pump are fixedly connected to the air outlet on the atomizer body through a three-way pipe. External gas enters the air pump through the air inlet pipe and flows out of the air pump through the air outlet pipe after compression.

[0013] Furthermore, two limiting rings are symmetrically fixedly installed at both ends of the main rotating shaft, and the limiting rings are placed on the side of the transmission plate away from the electromagnet, in order to prevent the transmission plate from falling off the main rotating shaft.

[0014] The beneficial effects of this invention are as follows:

[0015] This application provides a nebulization device for treating eye patients. During the operation of the nebulizer, the connection or disconnection of two electromagnets to the power supply is determined based on the volume change of the nebulized liquid in the nebulization cup. By starting and closing the two piston rods, the nebulization speed of the nebulized liquid in the nebulization cup is switched during the nebulization process. This slows down the formation speed of droplets inside the transparent eye mask, reducing the probability of reduced contact area between the droplets and the skin due to droplets adhering to the patient's eye skin surface. This ensures that the droplets can continuously and evenly adhere to the eye surface to exert their medicinal effect, thereby guaranteeing the nebulization effect, improving the utilization rate of the nebulized liquid, and ensuring nebulization efficiency. It also prevents the nebulization treatment time from being too long, allowing the patient to complete the nebulization treatment within a comfortable and tolerable duration.

[0024] 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.

[0025] See Figures 1 to 6A nebulization device for treating eye patients includes a nebulizer body 1 and a nebulizing cup 2 movably installed outside the nebulizer body 1. The nebulizing cup 2 is fixedly connected to the air outlet of the nebulizer body 1 through an air supply tube. The nebulizing cup 2 is also fixedly connected to a transparent goggle 3 through a droplet delivery tube. During nebulization, the patient wears the transparent goggle 3 on their head and adds nebulizing liquid into the nebulizing cup 2. The high-pressure airflow generated by the operation of the nebulizer body 1 flows through the air supply tube to the nebulizing cup 2 to break up the nebulizing liquid inside the nebulizing cup 2 and form droplets. The droplets then move through the droplet delivery tube to the transparent goggle 3 to perform nebulization treatment on the patient's eyes.

[0026] See Figure 2 The atomizer body 1 has a dual-axis motor 4 fixedly installed inside. The output end of the dual-axis motor 4 is fixedly connected to the main shaft 5. An electromagnet 6 is fixedly installed on one end of the main shaft 5 along with the dual-axis motor 4. A transmission plate 7 is symmetrically slidably installed on the outer side of the two electromagnets 6. The transmission plate 7 is slidably fitted on the outer side of the main shaft 5. The transmission plate 7 is made of ferromagnetic material. When the electromagnet 6 is energized, it generates an attraction force on the transmission plate 7, causing the transmission plate 7 to slide toward the electromagnet 6 and fit into the electromagnet 6.

[0027] See Figures 2 to 6 Two air pumps 8 are fixedly installed on the inner bottom wall of the atomizer body 1, and each air pump 8 is adapted to a corresponding transmission plate 7. One-way air inlet pipes 26 are fixedly connected to the side of each air pump 8. The ends of the two air inlet pipes 26 away from the air pump 8 are fixedly connected to the air inlets on the atomizer body 1 via T-junctions. One-way air outlet pipes 27 are also fixedly connected to the side of each air pump 8. The ends of the two air outlet pipes 27 away from the air pump 8 are fixedly connected to the air outlets on the atomizer body 1 via T-junctions. The top of the air pump 8... A piston connecting rod 9 is slidably mounted on the part. Two transmission wheels 10 are symmetrically connected to the outer sides of the two transmission plates 7. A connecting shaft 11 is fixedly mounted on the side of the transmission wheel 10 away from the transmission plate 7. The end of the connecting shaft 11 away from the transmission wheel 10 is rotatably connected to the piston connecting rod 9. The axis of the connecting shaft 11 does not coincide with the axis of the transmission wheel 10, that is, the connecting shaft 11 is placed at the eccentric position of the transmission wheel 10. Moreover, the distance between the two connecting shafts 11 and the axis of the corresponding transmission wheel 10 is different, that is, the eccentricity of the two is different.

[0028] When the main shaft 5 rotates, it drives the transmission wheel 10 to rotate via the electromagnet 6 and the transmission plate 7. The transmission wheel 10 drives the piston rod 9 to reciprocate in the vertical direction via the connecting shaft 11. This causes the bottom end of the piston rod 9 to reciprocate inside the air pump 8, compressing the gas entering the air pump 8 through the air inlet pipe 26 to form a high-pressure airflow. The high-pressure airflow then flows out through the air outlet pipe 27 to the air outlet on the nebulizer body 1, and then flows through the air delivery pipe to the nebulizer cup 2 to break up the nebulized liquid inside the nebulizer cup 2 and form droplets. Since the distance between the axes of the two connecting shafts 11 and the axis of the transmission wheel 10 is different, that is, the stroke of the two piston rods 9 reciprocating up and down is different, the volume of air compressed inside the air pump 8 is different, and the droplet concentration formed by the impact of the air on the nebulizer liquid in the nebulizer cup 2 is also different. The speed at which the droplets form droplets inside the transparent eye mask 3 and on the patient's eye is also different.

[0029] See Figures 2 to 6 A secondary rotating shaft 12 is fixedly installed on the side of the transmission wheel 10 away from the connecting shaft 11. Two support rods 23 are symmetrically fixedly installed on the side of the electromagnet 6 near the transmission plate 7. The end of the support rod 23 away from the electromagnet 6 is fixedly connected to the main hydraulic cylinder 13, providing support for the main hydraulic cylinder 13. The main hydraulic cylinder 13 is airtightly slidably connected to the main piston 14. A main piston rod 15 is fixedly installed on the side of the main piston 14 near the transmission plate 7, and the end of the main piston rod 15 away from the main piston 14 moves through the side wall of the main piston 14 and is fixedly connected to the transmission plate 7. A main spring 16 is fitted on the outside of the main piston rod 15, and the two ends of the main spring 16 are fixedly connected to the side wall of the main piston 14 and the inner side wall of the main hydraulic cylinder 13, respectively. The end of the main hydraulic cylinder 13 away from the transmission plate 7 is fixedly connected to the secondary hydraulic cylinder. The main hydraulic cylinder 17 has an airtight sliding connection to an auxiliary piston 18. An auxiliary piston rod 19 is fixedly connected to the end of the auxiliary piston 18 away from the main hydraulic cylinder 13. The end of the auxiliary piston rod 19 away from the auxiliary piston 18 moves through the side wall of the auxiliary hydraulic cylinder 17 and is rotatably mounted with a ball bearing 20. An auxiliary spring 22 is fitted on the outside of the auxiliary piston rod 19. The two ends of the auxiliary spring 22 are fixedly connected to the side wall of the auxiliary piston 18 and the inner side wall of the auxiliary hydraulic cylinder 17, respectively. Two slots 21 are symmetrically opened on the outside of the auxiliary rotating shaft 12. The two slots 21 are respectively engaged or disengaged from the corresponding ball bearing 20. The inside of the main hydraulic cylinder 13 and the rodless chamber of the auxiliary hydraulic cylinder 17 are filled with hydraulic medium. A connecting pipe 24 is fixedly connected to the outside of the main hydraulic cylinder 13 to allow the hydraulic medium to flow between the rod chamber and the rodless chamber of the main hydraulic cylinder 13.

[0030] When electromagnet 6 is not connected to a power source to generate an attractive force on transmission plate 7, neither the main spring 16 nor the auxiliary spring 22 is subjected to external force. Under the action of the elastic forces of the main spring 16 and the auxiliary spring 22, the hydraulic medium inside the main hydraulic cylinder 13 and the rodless chamber of the auxiliary hydraulic cylinder 17 is in a relatively balanced state. The ball 20 is not placed inside the slot 21 to engage the auxiliary shaft 12, and the transmission plate 7 is not in contact with electromagnet 6. After connecting the power source to electromagnet 6, the electromagnet 6 generates an attractive force on transmission plate 7, causing transmission plate 7 to slide towards electromagnet 6. This, in turn, drives the main piston 14 to slide synchronously through the main piston rod 15. The sliding of the main piston 14 displaces the hydraulic fluid in the rod chamber of the main hydraulic cylinder 13. The medium flows through the connecting pipe 24 into the rodless chamber of the main hydraulic cylinder 13. At this time, the auxiliary spring 22 is not subjected to external force to squeeze the hydraulic medium. Under the squeezing action of the main piston 14, the hydraulic medium entering the rodless chamber of the main hydraulic cylinder 13 cannot flow in the reverse direction through the connecting pipe 24. Therefore, as the main piston 14 slides, more hydraulic medium enters the rodless chambers of the main hydraulic cylinder 13 and the auxiliary hydraulic cylinder 17, thereby squeezing the auxiliary piston 18 and the auxiliary spring 22. The auxiliary piston rod 19 and the ball 20 slide towards the auxiliary rotating shaft 12 and exert a certain pressure on the surface of the auxiliary rotating shaft 12. At this time, because the auxiliary piston rod 19 of the ball 20 is rotatably connected, and the contact surface between the ball 20 and the outer surface of the auxiliary rotating shaft 12 is... Because the volume is relatively small, when the main rotating shaft 5 drives the main hydraulic cylinder 13 and the auxiliary hydraulic cylinder 17 to rotate via the electromagnet 6 and the support connecting rod 23, the ball 20 will slide on the outer surface of the auxiliary rotating shaft 12. When the ball 20 slides to the slot 21, it releases the restriction of the auxiliary rotating shaft 12 on the auxiliary piston rod 19 and the ball 20, allowing the end of the auxiliary piston rod 19 and the ball 20 near the auxiliary rotating shaft 12 to slide into the slot 21, forming a locking connection with the auxiliary rotating shaft 12. This achieves the purpose of driving the auxiliary rotating shaft 12 and the transmission wheel 10 to rotate together, and drives the piston connecting rod 9 to reciprocate in the vertical direction via the connecting shaft 11 to compress the gas inside the air pump 8. When it is necessary to switch the reciprocating piston... When the connecting rod is in position 9, the electromagnet 6, which has not yet generated magnetism, is first connected to the power supply to generate magnetism. Then, the power supply to the current electromagnet 6 is cut off. When the electromagnet 6 loses its attraction to the transmission plate 7, under the action of the spring force of the main spring 16 and the spring force of the auxiliary spring 22, the main piston 14 and the main piston rod 15 slide back to the auxiliary hydraulic cylinder 17. The auxiliary piston 18 and the auxiliary piston rod 19 also slide back to the direction away from the auxiliary rotating shaft 12 to release the jamming of the auxiliary rotating shaft 12. This causes the auxiliary rotating shaft 12 to no longer rotate with the main hydraulic cylinder 13. The hydraulic medium in the rodless chamber of the main hydraulic cylinder 13 and the rodless chamber of the auxiliary hydraulic cylinder 17 is squeezed and flows through the connecting pipe 24 to the rod chamber of the main hydraulic cylinder 13 in preparation for the next jamming.

[0031] Two limiting rings 25 are symmetrically fixed at both ends of the main rotating shaft 5, and the limiting rings 25 are placed on the side of the transmission plate 7 away from the electromagnet 6. When the transmission plate 7 is reset under the action of the main spring 16 and the secondary spring 22, the limiting rings 25 prevent the transmission plate 7 from falling off the main rotating shaft 5.

[0032] A liquid level sensor (not shown in the figure) is fixedly installed inside the nebulizer cup 2, and the liquid level sensor is electrically connected to the controller inside the nebulizer body 1. When the nebulizer body 1 is running, initially, the electromagnet 6 with the long eccentricity is powered on, causing the piston rod 9 to reciprocate with a longer stroke. This results in a larger volume of compressed air in the air pump 8, leading to greater air pressure and flow rate. This allows for rapid impact of the nebulized liquid in the nebulizer cup 2 to generate droplets for nebulization treatment of the patient's eyes. As the treatment progresses, the nebulized liquid in the nebulizer cup 2 gradually decreases. When the liquid level reaches a certain value... When the liquid level of the nebulizer is lower than the liquid level sensor, the liquid level sensor sends a signal to the controller. The controller outputs a control signal to turn on the power to the electromagnet 6 corresponding to the short eccentricity and then turn off the power to the electromagnet 6 corresponding to the long eccentricity, thus completing the start and stop of the two piston rods 9. In this way, during the nebulization process, the formation rate of droplets inside the transparent eye mask 3 is slowed down, reducing the probability of the contact area between the droplets and the skin being reduced due to droplets adhering to the patient's eye skin surface. This ensures the nebulization effect, improves the utilization rate of the nebulizing liquid, and also prevents the nebulization treatment time from being too long.

[0033] Since both air intake pipes 26 can only allow air to enter in one direction, when the power supply to the electromagnet 6 corresponding to the short eccentricity is turned on while the power supply to the electromagnet 6 corresponding to the long eccentricity is not turned off, the auxiliary piston rod 19 and the ball 20 corresponding to the short eccentricity will not immediately slide into the slot 21 and drive the auxiliary shaft 12 to rotate. At this time, the piston rod 9 corresponding to the long eccentricity will still reciprocate to compress the gas. Since the longest sliding distance between the auxiliary piston rod 19 and the slot 21 after the electromagnet 6 is energized and pressed against the surface of the auxiliary shaft 12 is one-quarter of the circumference of the vertical section of the auxiliary shaft 12, the auxiliary piston rod 19 and the ball 20 can quickly slide to the slot 21 and slide into the slot 21 to engage the auxiliary shaft 12. This will not affect the switching speed of the piston rods 9 corresponding to the long and short eccentricities, thus preventing the atomizer body 1 from stopping the formation of droplets.

[0034] Working principle:

[0035] During nebulization, the patient wears the transparent goggles 3 on their head, adds the nebulizing liquid into the nebulizer cup 2, and presses the switch to start the nebulizer body 1. Initially, the long eccentricity corresponding electromagnet 6 is powered on, and the electromagnet 6 generates an attraction force on the transmission plate 7, which slides towards the electromagnet 6. This, in turn, drives the main piston 14 to slide synchronously via the main piston rod 15. The sliding of the main piston 14 causes the hydraulic medium in the rod chamber of the main hydraulic cylinder 13 to flow through the connecting pipe 24 to the rodless chamber of the main hydraulic cylinder 13, thereby squeezing the auxiliary piston 18 and the auxiliary spring 22. The auxiliary piston rod 19 and the ball 20 slide towards the auxiliary rotating shaft 12, exerting a certain pressure on the surface of the auxiliary rotating shaft 12. At this time, because the auxiliary piston rod 19 of the ball 20 is rotatably connected, and the contact area between the ball 20 and the outer surface of the auxiliary rotating shaft 12 is small, when the main rotating shaft 5 drives the main hydraulic cylinder 13 and the auxiliary hydraulic cylinder 17 to rotate via the electromagnet 6 and the support connecting rod 23... When in motion, the ball 20 slides on the outer surface of the secondary rotating shaft 12. When the ball 20 slides to the slot 21, the restriction of the secondary rotating shaft 12 on the secondary piston rod 19 and the ball 20 is released, allowing the end of the secondary piston rod 19 and the ball 20 near the secondary rotating shaft 12 to slide into the slot 21, forming a locking with the secondary rotating shaft 12. This causes the secondary rotating shaft 12 and the transmission wheel 10 to rotate together. The transmission wheel 10 drives the piston connecting rod 9 to move back and forth in the vertical direction through the connecting shaft 11, thereby causing the bottom end of the piston connecting rod 9 to move back and forth inside the air pump 8 to compress the gas entering the air pump 8 through the air inlet pipe 26 to form a high-pressure airflow. The high-pressure airflow then flows out through the air outlet pipe 27 to the air outlet on the nebulizer body 1, and then flows through the air delivery pipe to the nebulizer cup 2 to break the nebulized liquid inside the nebulizer cup 2 and form droplets. The droplets then move through the delivery pipe to the transparent eye mask 3 to perform nebulization treatment on the patient's eyes.

[0036] As the treatment progresses, the nebulizer fluid in the nebulizer cup 2 gradually decreases. When the fluid level is below the level sensor, the sensor sends a signal to the controller. The controller then outputs a control signal to power on the electromagnet 6 corresponding to the short eccentricity. The short eccentricity electromagnet 6, following the same process as the long eccentricity electromagnet 6 when powered on, drives the corresponding piston rod 9 to reciprocate vertically, creating a high-pressure airflow to break up the nebulizer fluid inside the nebulizer cup 2 and form droplets. Then, the power to the long eccentricity electromagnet 6 is disconnected. After the iron plate 6 loses its attraction to the transmission plate 7, under the action of the spring force of the main spring 16 and the spring force of the auxiliary spring 22, the main piston 14 and the main piston rod 15 slide back to the auxiliary hydraulic cylinder 17. The auxiliary piston 18 and the auxiliary piston rod 19 also slide back to the direction away from the auxiliary rotating shaft 12 to release the locking of the auxiliary rotating shaft 12, so that the auxiliary rotating shaft 12 no longer rotates with the main hydraulic cylinder 13. The hydraulic medium in the rodless chamber of the main hydraulic cylinder 13 and the rodless chamber of the auxiliary hydraulic cylinder 17 is squeezed and flows through the limiting ring 25 to the rod chamber of the main hydraulic cylinder 13 in preparation for the next locking.

[0037] By switching the piston rods 9 on and off, the atomization speed of the nebulizer liquid in the nebulizer cup 2 is switched during the nebulization process. This slows down the formation speed of droplets inside the transparent eye mask 3, reducing the probability of the droplets reducing the contact area between the droplets and the skin due to droplets adhering to the patient's eye skin surface. This ensures that the droplets can continuously and evenly adhere to the eye surface to exert their medicinal effect, thereby guaranteeing the nebulization effect, improving the utilization rate of the nebulizer liquid, and ensuring nebulization efficiency. It also prevents the nebulization treatment time from being too long, allowing the patient to complete the nebulization treatment within a comfortable and tolerable duration.
