Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to an ultrasonic nebulizer for ophthalmology. Background Technology

[0002] Ophthalmic ultrasonic nebulizers are therapeutic tools that transform water or medication into atomized droplets (aerosols) to act on the eyes. They are among the highest-performing nebulizers, characterized by large mist volume and small, uniform droplets. Widely used abroad since the late 1960s, they have recently been introduced to the Chinese market. Ophthalmic nebulization therapy offers advantages such as low medication dosage, fewer side effects, convenience, and rapid onset of action, and is widely used in clinical ophthalmology. It can be used alone to promote the resolution of local inflammation and accelerate tissue repair, or combined with traditional Chinese medicine non-drug therapies such as acupuncture and massage. Significant results have been achieved in treating dry eye syndrome, keratitis, conjunctivitis, eyelid diseases, and amblyopia / strabismus.

[0003] Currently, most ultrasonic nebulizers used in ophthalmology are designed with knobs or buttons for adjusting operating parameters such as mist output, airflow, and temperature. However, knob or button adjustments are inconvenient and lack the precision required for ophthalmic procedures. Furthermore, ophthalmic ultrasonic nebulizers often lack heating functionality or only have basic heating (single-time heating), making it impossible to heat the water mist quickly enough for effective warm compresses or steam treatments on the patient's eyes.

[0004] Most existing ultrasonic nebulizers used in ophthalmology feature an integrated water tank and main unit design. Because doctors need to add medication during nebulization to meet the needs of different patients, cleaning after use is inconvenient and can easily lead to medication residue. This not only poses a health risk to patients but also increases the likelihood of corrosion inside the water tank, shortening its lifespan. Furthermore, the diaphragm of an ultrasonic nebulizer wears down during use, causing energy loss. The integrated design requires replacing the entire unit, and the need for a drain outlet in the water tank area creates a risk of leakage and electric shock. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic nebulizer for ophthalmology that is easy to clean, can quickly heat water mist, is simple to maintain, and is safer to use.

[0006] This utility model is achieved through the following technical solution: an ultrasonic nebulizer for ophthalmology, comprising a main unit and a water tank embedded on one side of the main unit. The water tank includes a lower base, a middle tank body, and an upper tank cover. An ultrasonic nebulizing plate is disposed between the base and the tank body. A first air duct is disposed on the side of the tank body facing the main unit, and the upper part of the first air duct communicates with the inner side of the tank cover. A second air duct is disposed inside the main unit and communicates with the lower opening of the first air duct. A fan is disposed at the free end of the second air duct, and a heating element is disposed inside the second air duct. A mist outlet is disposed on the upper part of the tank cover, and a self-heating nebulizing tube is connected to the mist outlet.

[0007] The working principle of this technical solution is based on a dual heating mode, employing both hot air blowing from the main unit and self-heating of the atomizing tube. It utilizes both air heating and mist output heating to rapidly heat the mist particles, achieving a rapid temperature rise while also providing eye heat therapy. The separate design of the water tank and main unit facilitates cleaning. The ultrasonic atomizing plate is placed inside the water tank, allowing for easy replacement without disassembling the main unit by separating the tank from the base. Furthermore, the air duct design of the water tank and main unit ensures normal mist output while preventing water ingress, making it safer to use.

[0008] To better realize this utility model, the upper part of the tank is further fitted with a cup holder, the cup holder contains a medicine cup, and the lower part of the medicine cup is placed in the tank.

[0009] To better realize this utility model, the upper part of the groove cover is further provided with an injection hole, and a sealing plug is embedded in the injection hole.

[0010] To better realize this utility model, the main unit further includes a lower mounting base and an upper outer shell. A filter frame mounted on the mounting base is provided inside the outer shell. The fan is mounted on the filter frame. External air enters the fan from the filter frame and is then blown by the fan to the second air duct.

[0011] To better realize this utility model, a control screen is further embedded on the upper surface of the outer shell, a screen frame is embedded on the surface of the control screen, and a motherboard electrically connected to the control screen is also provided inside the outer shell. The motherboard is connected to the outside through a power module with a power interface, and the motherboard provides power to the ultrasonic atomizing plate in the water tank through the cooperation of the plug and slot.

[0012] To better realize this utility model, the atomizing tube further includes a heating tube in the middle, one end of which is a mist inlet and the other end is a mist outlet. A heating resistance wire is embedded in the outer wall of the heating tube in a closed manner. An aviation head with a built-in plug is provided at the upper part of the mist inlet, and an oxygen injection port communicating with the heating tube is provided at the lower part of the mist inlet. A plug is embedded in the oxygen injection port. The mist inlet and the mist outlet are also respectively provided with thermistors connected to the aviation head. The aviation head is connected to an external cable to provide power to the heating resistance wire and transmit the temperature information fed back by the thermistor.

[0013] To better realize this utility model, rubber pads are further provided at the four corners of the bottom of the main unit.

[0014] To better realize this utility model, a sealing ring is further provided at the connection between the first air duct and the second air duct.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] (1) This utility model adopts a dual heating mode of hot air blowing from the main unit and self-heating of the atomizing tube. It can heat the mist particles by relying on air heating and mist heating together, which can achieve the effect of rapid temperature rise and also realize eye hot compress.

[0017] (2) The separate structure design of the water tank and the main unit of this utility model makes it easy to clean. The ultrasonic atomizing plate is placed in the water tank, so the ultrasonic atomizing plate can be replaced directly by separating the tank and the base without disassembling the main unit.

[0018] (3) The air duct structure design of the water tank and the main unit of this utility model can ensure that water mist is blown out normally while avoiding water ingress, making it safer to use;

[0019] (4) This utility model provides a new ultrasonic nebulizer for ophthalmology, which has a high nebulization frequency and small nebulized particles. Its design of separating the medicine solution and water tank makes it easy to replace and add medicine solution. It is suitable for ocular nebulization treatment. It can be selected for two operating modes: heating and non-heating. In the heating mode, the heating temperature can reach 43°C, which can effectively soften solidified meibomian gland lipids and unclog meibomian glands. It is more convenient for actual clinical use and is suitable for widespread application. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly including one or more of the feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0043] The main structure of this embodiment is as follows: Figures 1-6 As shown, the device includes a main unit 1 and a water tank 2 embedded on one side of the main unit 1. The water tank 2 includes a lower base 21, a middle tank body 22, and an upper tank cover 23. An ultrasonic atomizing plate 3 is disposed between the base 21 and the tank body 22. A first air duct 24 is disposed on the side of the tank body 22 facing the main unit 1, and the upper part of the first air duct 24 is connected to the inner side of the tank cover 23. A second air duct 15 is disposed inside the main unit 1 and is connected to the lower opening of the first air duct 24. A fan 14 is disposed at the free end of the second air duct 15, and a heating element 16 is disposed inside the second air duct 15. A mist outlet 25 is disposed on the upper part of the tank cover 23, and an atomizing tube 4 with a self-heating effect is connected to the mist outlet 25.

[0044] The specific usage process is as follows: Water is introduced into the tank 22, then the tank 22 is placed on the base 21, and then the tank cover 23 is put on to complete the assembly of the water tank 2. Then the entire water tank 2 is embedded in one side of the main unit 1. During the embedding process, the first air duct 24 of the water tank 2 is connected to the second air duct 15, and the ultrasonic nebulizer 3 is electrically connected. Then the nebulizer tube 4 with self-heating effect is connected to the mist outlet 25, and the nebulizer tube 4 is connected to the eye mask worn by the patient.

[0045] When the main unit 1 is running, the self-heating function of the heating element 16 in the second air duct 15 and the atomizing tube 4 can be selected. If it is turned on, the airflow blown by the fan 14 will be heated by the heating element 16 in the second air duct 15 and then enter the second air duct 24, and finally enter the tank cover 23. At this time, the ultrasonic atomizing plate 3 at the bottom of the tank 22 will atomize the water in the tank 22. The water mist will pass through the hot airflow in the tank cover 23 and enter the atomizing tube 4 through the mist outlet 25. After being heated by the atomizing tube 4, it will flow to the patient's eyes to perform atomization treatment on the patient's eyes. Example 2:

[0046] This embodiment further defines the structure of the water tank 2 based on the above embodiment, such as... Figure 4 As shown, a cup holder 26 is also embedded in the upper part of the tank 22, and a medicine cup 27 is placed inside the cup holder 26. The lower part of the medicine cup 27 is placed inside the tank 22. The addition of the medicine cup 27 and cup holder 26 separates the medicine from the water in the tank 22. This prevents excessive dilution of the medicine, ensuring the concentration of the medicine applied to the eyes and conserving medicine. Furthermore, no medicine residue remains in the tank 22, preventing adverse effects when using other medicines. The tank 2 is also protected from corrosion by the medicine, making cleaning easier. Other parts of this embodiment are the same as those in the previous embodiment and will not be described again. Example 3:

[0047] This embodiment further defines the structure of the water tank 2 based on the above embodiment, such as... Figure 4 As shown, the upper part of the tank cover 23 is also provided with an injection hole 28, and a sealing plug 29 is embedded in the injection hole. The sealing plug 29 can prevent external impurities from entering the water tank 2 through the injection hole 28. The needle of the syringe can directly pass through the sealing plug 29 and inject the medicine directly into the medicine cup 27 through the injection hole 28, which can facilitate the replacement and addition of medicine, allowing the eyes to receive nebulized medicine treatment for a longer period of time. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again. Example 4:

[0048] This embodiment further defines the structure of host 1 based on the above embodiments, such as... Figure 3 As shown, the main unit 1 includes a lower mounting base 11 and an upper outer casing 12. A filter frame 13, mounted on the mounting base 11, is disposed within the outer casing 12. A fan 14 is mounted on the filter frame 13. External air enters the fan 14 through the filter frame 13 and is then blown towards the second air duct 15. Since the fan 14 draws in external air through the filter frame 13 and blows it towards the second air duct 15, and the second air duct 15 is connected to the first air duct 24, providing the flow power for the water mist generated throughout the water tank 2, the filter frame 13 is specially designed to filter the incoming external air in order to prevent impurities from entering. Other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 5:

[0049] This embodiment further defines the structure of host 1 based on the above embodiments, such as... Figure 3 As shown, a control screen 17 is embedded on the upper surface of the outer casing 12, and a screen frame 18 is embedded on the surface of the control screen 17. A main board 19 electrically connected to the control screen 17 is also provided inside the outer casing 12. The main board 19 connects to the outside via a power module and provides power to the ultrasonic atomizing plate 3 in the water tank 2 through the cooperation of a plug-in board and a slot. Compared to the traditional method of adjusting the airflow rate and atomization rate via buttons and knobs, this invention uses integrated circuit board and control chip technology. Through the touch screen control technology of the control screen, precise adjustment of atomization volume, airflow, and temperature can be achieved. Furthermore, the overall operation of the atomizer can be displayed more intuitively, and faults can be detected and alarmed in a timely manner. A slot is provided at the bottom of the water tank 2, below the first air duct 24, which completely prevents water from contacting the water in the tank, further ensuring safety. Other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 6:

[0050] This embodiment further defines the structure of the atomizing tube 4 based on the above embodiments, such as... Figure 5 , Figure 6As shown, the nebulizer tube 4 includes a heating tube 42 in the middle. One end of the heating tube 42 is a mist inlet 41, and the other end is a mist outlet 43. A heating resistance wire 44 is embedded in the outer wall of the heating tube 42 in a closed manner. An aviation head 45 with a built-in plug is provided at the upper part of the mist inlet 41, and an oxygen injection port 46 communicating with the heating tube 42 is provided at the lower part of the mist inlet 41. A plug 47 is embedded in the oxygen injection port 46. Thermistors 48 connected to the aviation head 45 are also provided in the mist inlet 41 and the mist outlet 43, respectively. The aviation head 45 is connected to an external cable to provide power to the heating resistance wire 44 and transmit the temperature information fed back by the thermistor 48. The self-heating function of the nebulizer tube 4 is provided by the heating resistance wire 44, which is embedded in the outer wall of the heating tube 42 in a closed manner and does not come into contact with water mist. Therefore, the inner wall of the heating tube 42 is smooth and easy to clean. The oxygen injection port 26 is mainly for connecting the oxygen delivery tube to provide oxygen therapy for the eyes. The other parts of this embodiment are the same as those in the above embodiments, and will not be described again. Example 7:

[0051] This embodiment further defines the structure of host 1 based on the above embodiments, such as... Figure 3 As shown, rubber pads 5 are also provided at the four corners of the bottom of the main unit 1. The main purpose of adding rubber pads 5 is to ensure the stability of the main unit 1 during nebulization treatment. As a bottom buffer structure, the rubber pads 5 can ensure the stability of the main unit 1 even on slightly inclined or uneven surfaces. In addition, the fan 14 draws air from the bottom of the mounting base 11. The rubber pads 5 allow the bottom of the mounting base 11 to be suspended in the air, so as not to block the air intake of the filter frame 13. Furthermore, the air intake process of the filter frame 13 will also create a negative pressure at the bottom of the mounting base 11, further ensuring the overall stability of the main unit 1. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again. Example 8:

[0052] This embodiment, based on the above embodiment, further adds a sealing ring 6, such as... Figure 3 As shown, to ensure a tight seal and connection between the first air duct 24 and the second air duct 15, a sealing ring 6 is installed at the connection point between the first air duct 24 and the second air duct 15. This ensures that the hot air blown out by the fan 14 can directly blow onto the slot cover 23 and will not enter the main unit 1, thus affecting the normal operation of the internal components of the main unit 1. It is understood that the working principles and processes of components such as the control panel 17 and the ultrasonic atomizing plate 3, according to an embodiment of this utility model, are existing technologies and well-known to those skilled in the art, and will not be described in detail here. Example 9:

[0053] Based on the above embodiments, this embodiment further adds an alarm function. The ultrasonic atomizer also has a variety of built-in sensors to realize intelligent monitoring alarms such as over-temperature alarm, air supply failure alarm, temperature measurement failure alarm, mist output heating alarm, air intake heating alarm, water shortage alarm, and water tank connection failure alarm. The chip built into its motherboard is equipped with corresponding solution prompts for the faults that occur, which can control the energy output that may cause harm after the fault to the maximum extent, making the product simple, safe and reliable to use.

[0054] The specific operation process is as follows:

[0055] I. Functions

[0056] 1. Screen Saver: Enters screen saver mode after 60 seconds of continuous standby;

[0057] 2. After a 6-second animation plays during startup, the device enters the standby screen. Figure 7 As shown;

[0058] 3. After the countdown ends, the atomization will stop, and after three "beep beep beep" alarm sounds, the time will reset and the device will enter standby mode.

[0059] 4. Factory settings, such as Figure 8 As shown;

[0060] 5. Parameter adjustment

[0061] Atomization rate: 20%-100%, adjustable in 1% increments, long press for continuous adjustment, noticeable changes in atomization effect;

[0062] Air volume: 40%-100%, adjustable in 1% intervals, long press for continuous adjustment, the size of the mist output changes significantly;

[0063] Temperature: 25℃-43℃, adjustable in 0.5℃ increments, long press for continuous adjustment;

[0064] Time: 1-60 minutes, adjustable in 1-minute intervals, long press for continuous adjustment;

[0065] Fog temperature detection display range: 10℃-60℃; heating to 43℃ for 45 seconds.

[0066] II. Alarm Prompt

[0067] 1. Over-temperature protection: Heating stops, and the mist outlet heating icon turns OFF; if the temperature exceeds 2℃, a continuous "beep" alarm sound will beep, and the temperature will drop back to normal; if the mist outlet temperature reaches 50℃, the instrument will automatically stop working and return to standby mode. It will only operate normally when the temperature drops below 50℃. (A thermistor is installed at the mist outlet of the atomizing tube to detect the mist outlet temperature. When the mist outlet temperature exceeds the set value, over-temperature protection is activated - heating stops.)

[0068] 2. Restart the work, such as Figure 9 As shown,

[0069] 3. Temperature Measurement Failure: In standby or operating mode, the temperature detection of the mist outlet tube is abnormal. A fault page will pop up, accompanied by a looping "beep, beep" alarm sound, and misting will be disabled. If the problem persists after returning to the homepage, the buzzer will continue to sound, and the temperature display will show 10℃. Figure 10 As shown.

[0070] 4. Fog outlet heating failure: The fog outlet pipe cannot heat properly.

[0071] (1) First, the fog heating icon changes to BAD, and at the same time, a "beep, beep" alarm sound is heard repeatedly, such as Figure 11 As shown;

[0072] (2) After 10 seconds of continuous alarm, the atomization stops and the alarm sound stops. A fault page for the mist heating system pops up, such as... Figure 12 As shown; (An AD voltage detection was added to the heating circuit design. When the mist outlet tube cannot heat properly, its voltage value will change. If the change exceeds the set value, the system mist outlet heating icon will turn to BAD, and a "beep, beep" alarm sound will be heard repeatedly. After 10 seconds of continuous alarm, misting will stop, the alarm sound will stop, and a mist outlet heating system fault page will pop up.)

[0073] 5. Air supply system failure: The air supply fan fails to turn due to circuit issues during operation.

[0074] The atomization stops, a fault page pops up, and only one "beep" alarm sound is heard. Figure 13 As shown. (An AD voltage detection was added to the fan circuit design. When the fan stops rotating due to circuit factors, its voltage value will change. If the change exceeds the set value, the system will pop up a fault page and only a "beep" alarm sound will be heard.)

[0075] 6. Air heating failure: The heating element does not heat up.

[0076] (1) The air heater icon changes to BAD and a "beep, beep" alarm sound loops continuously, such as Figure 14 As shown

[0077] (2) After 40 seconds of continuous alarm, the atomization stops, the alarm sound stops, and a fault page pops up, such as Figure 15 As shown. (An AD voltage detection was added to the air heating circuit design. When the air heater fails to work due to circuit factors, its voltage value will change. If the change exceeds the set value, the system will change the air heater icon to BAD status and simultaneously emit a "beep, beep" alarm sound. After 40 seconds of continuous alarm, the atomization will stop, the alarm sound will stop, and a fault page will pop up.)

[0078] 7. Air heating detection fault: The system does not detect the air temperature during operation, allowing continued atomization, but the air heating icon changes to OFF, stopping air heating. (Example: ...) Figure 16 As shown. (A thermistor is installed on the heating element to detect the heating temperature. When the heating temperature exceeds the set value, the system will turn the air heating icon to the OFF state and stop air heating.)

[0079] 8. Water tank connection failure: Poor contact between the circuit interface at the bottom of the water tank and the host interface.

[0080] No alarm sound, a fault alarm page pops up, and atomization is prohibited. Figure 17 As shown.

[0081] (A connection detection circuit is designed on the circuit board at the bottom of the water tank. When the circuit interface at the bottom of the water tank is not in good contact with the host interface, the system will detect the disconnection and pop up a fault alarm page, prohibiting atomization.)

[0082] 9. Water shortage alarm: When the water level in the tank is lower than the indicated level, or there is poor contact between the tank and the main unit's connection pin.

[0083] When the atomization stops, an alarm page pops up, but there is no alarm sound. Figure 18 As shown.

[0084] (A water level detection switch is installed on the ultrasonic atomizing plate. When the water level is lower than the detection switch or when the detection pin of the connector has poor contact, the system will detect the lack of water, stop atomization, and pop up an alarm page.)

[0085] III. Electrical Parameters

[0087] 2. Output: DC 24V 5A

[0088] 3. Standby power: 3W; Maximum operating power: 110W

[0089] This ultrasonic nebulizer is specifically designed and developed for ophthalmic ultrasonic nebulization, with functions and parameters better suited to the needs of clinical ophthalmic work: its nebulization frequency is 2.4MHz, higher than conventional nebulizers; the median equivalent particle size is 5mm, and the percentage (volume distribution) of particles smaller than 5mm is ≥50%. Based on ophthalmic ultrasonic nebulization, it is more conducive to the absorption of medication by the ocular surface; it offers two operating modes: heated and non-heated. In heated mode, the temperature can reach 43℃, effectively softening solidified meibomian gland lipids and unblocking the meibomian glands, making it more convenient for actual clinical use.

[0090] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
