Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a micro-upgraded precision-controlled electronic atomizer for eye administration. Background Technology

[0002] According to patent document CN204618556U, a medical aid device is disclosed, specifically an ocular drug delivery device. It includes a drug nebulizer and an eye mask. The drug nebulizer outputs nebulized medication to the area enclosed by the eye mask and the eye for drug delivery. The entire device uses the drug nebulizer to atomize the liquid medication and then directly delivers the atomized medication to the area enclosed by the eye mask and the eye for drug delivery. It does not require the patient or nurse to hold it, making it convenient to use.

[0003] The aforementioned documents and existing technologies have the following problems: Current ocular electronic nebulizers have shortcomings in drug dosage control. Traditional drug delivery methods are difficult to control the dosage precisely, resulting in large deviations in dosage. Insufficient dosage may affect the treatment effect, or excessive dosage may cause adverse reactions. Furthermore, there is a lack of timely and effective means to evaluate the drug's effectiveness. It is usually impossible to quickly and accurately determine whether the drug has taken effect or whether vision has improved after administration, making it difficult to adjust the treatment plan in a timely manner according to the actual situation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a micro-upgraded, precise dosage control electronic nebulizer for eye administration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a micro-upgrade precision-controlled electronic atomizing drug delivery device for the eyes, comprising an outer shell, an inner material chamber inside the outer shell, an atomizing plate on the side of the inner material chamber, an inlet pipe on the top surface of the inner material chamber, a flow meter inside the inlet pipe, a micro-control valve inside the inlet pipe, an outer material chamber on the top surface of the inner material chamber, a lower cover on the bottom surface of the outer shell, a lens chamber on the bottom surface of the lower cover, a vision chart lens inside the lens chamber, and an eye focusing lens inside the lens chamber.

[0006] Preferably, the outer casing has a display screen on its side and a through hole on its side.

[0007] Preferably, a battery is located inside the housing, and a circuit board is located inside the housing.

[0008] Preferably, the flow meter is electrically connected to the circuit board, and the micro-control valve is electrically connected to the circuit board.

[0009] Preferably, the vision chart lenses are arranged in three equidistant positions, and the eye focusing lens is located at the bottom of the vision chart lenses.

[0010] Preferably, the shape of the outer material bin is adapted to the outer shell, and the outer material bin is connected to the inner material bin through a liquid inlet pipe.

[0011] Preferably, the position of the atomizing plate corresponds to the position of the through hole, and the bottom surface of the outer material bin is movably connected to the top surface of the inner material bin.

[0012] Beneficial effects

[0013] This invention employs a lens compartment, an eye-focusing lens, and a vision chart lens. After the user completes the ocular nebulization drug delivery, they can directly use the three vision chart lenses, equidistantly arranged in the lens compartment at the bottom of the device, to test their vision from different distances and determine whether their vision is clear. The eye-focusing lens, located at the bottom of the vision chart lens, helps the user to better focus on the vision chart, making the test results more accurate. This integrated design allows the user to quickly and accurately determine whether the drug has taken effect and whether their vision has improved after delivery, thus facilitating timely adjustments to the treatment plan based on the actual situation and greatly improving the effectiveness and specificity of ocular drug delivery treatment.

[0014] In this invention, an inlet pipe, a flow meter, and a micro-control valve are used. The inlet pipe serves as the drug delivery channel, and its internal flow meter can accurately measure the drug flow rate in real time and feed the data back to the circuit board. The micro-control valve receives instructions from the circuit board based on the flow meter data and precisely adjusts the valve opening. During drug administration, according to the preset dosage, a certain amount of drug enters the atomization area of ​​the inner material chamber through the metering channel through the close cooperation of the flow meter and the micro-control valve, achieving precise control of the drug delivery volume. This avoids the dosage deviation problem caused by the inability to accurately control the dosage in traditional drug administration methods, reduces the risk of insufficient dosage affecting the treatment effect or excessive dosage causing adverse reactions, and greatly improves the safety and effectiveness of ocular drug delivery therapy.

[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 1-5 A micro-upgraded precision-controlled electronic nebulizer for eye administration includes a housing 1, which serves as the external protective structure for the entire device, housing and securing the internal components, providing protection and support. A display screen 5 is located on the side of the housing 1, displaying various information such as dosage and device status, allowing users to intuitively understand the device's operation. A through-hole 15 is located on the side of the housing 1, with the position of the atomizing plate 4 corresponding to the through-hole 15. The through-hole 15 is the channel through which the atomized medication is sprayed, allowing the medication to act on the eyes. A battery 10 is located inside the housing 1, providing power to the entire device and ensuring the normal operation of all electronic components. A circuit board 11 is located inside the housing 1, serving as the device's control core. The circuit board 11 connects to a flow meter 13 and a micro-control valve 14, receiving data from the flow meter 13 and issuing commands to the micro-control valve 14 according to preset programs and data to achieve precise control of the medication flow. It also handles other sensor data, atomizes the atomizing plate 4, and controls the display screen 5.

[0026] The outer casing 1 contains an inner material chamber 2, which stores the liquid medicine flowing in from the outer material chamber 3 through the inlet pipe 12. An atomizing plate 4 on its side atomizes the liquid medicine in the inner material chamber 2, preparing it for eye administration. The atomizing plate 4 operates based on ultrasonic principles. When the circuit board 11 transmits electrical energy to the atomizing plate 4, the piezoelectric ceramic material within the atomizing plate 4 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 within the ultrasonic band. This high-frequency vibration is transmitted to the liquid medicine in the inner material chamber 2, which is in contact with the atomizing plate 4, generating a strong shear force on the surface of the liquid medicine. The molecules on the surface of the liquid medicine are subjected to this high-frequency vibration and shear force. Under the action of the liquid, it overcomes its own surface tension and is torn into tiny droplets. These tiny droplets are rapidly dispersed by the surrounding air to form tiny mist droplets, thus realizing the transformation of liquid medicine into gaseous mist droplets and completing the atomization function. The top surface of the inner material chamber 2 is provided with a liquid inlet pipe 12, which serves as a medicine transfer channel, connecting the outer material chamber 3 and the inner material chamber 2, so that the medicine can flow from the outer material chamber 3 into the inner material chamber 2. The flow meter 13 and micro-control valve 14 installed inside the pipe precisely control the flow rate of the medicine. The flow meter 13 inside the pipe 12 measures the flow rate of the medicine in the pipe 12 in real time and feeds the flow data back to the circuit board 11, providing data basis for precise control of the dosage.

[0027] A micro-control valve 14 is installed inside the inlet pipe 12. The micro-control valve 14 receives instructions from the circuit board 11 based on data from the flow meter 13, and controls the amount of liquid entering the inner hopper 2 by precisely adjusting the valve opening, thus achieving precise flow control. The flow meter 13 and the micro-control valve 14 are electrically connected to the circuit board 11. An outer hopper 3 is provided on the top surface of the inner hopper 2. The shape of the outer hopper 3 is adapted to the outer shell 1. The outer hopper 3 is connected to the inner hopper 2 through the inlet pipe 12. The bottom surface of the outer hopper 3 is movably connected to the top surface of the inner hopper 2. The outer hopper 3 stores the liquid and provides a continuous supply of liquid to the inner hopper 2. Electromagnetic seats are provided on both the bottom surface of the outer hopper 3 and the top surface of the inner hopper 2. The outer material compartment 3 can be easily replaced via a corresponding electromagnetic base. The bottom surface of the outer casing 1 is provided with a lower cover 9, and the bottom surface of the lower cover 9 is provided with a lens compartment 6. The lens compartment 6 is used to accommodate the visual acuity chart lens 7 and the eye focusing lens 8, providing structural support for vision testing. The lens compartment 6 contains the visual acuity chart lens 7 and the eye focusing lens 8. There are three visual acuity chart lenses 7 equidistantly arranged. The eye focusing lens 8 is located at the bottom of the visual acuity chart lens 7. After the user completes the eye nebulization drug delivery, these visual acuity chart lenses 7 can be used to test vision from different distances to determine whether the person's vision is clear, and to help determine whether the drug has taken effect and whether the vision condition has improved.

[0028] When using this micro-upgraded precision-controlled electronic nebulizer for eye administration, turn on the device, power it with battery 10, and start the circuit board 11. Set the dosage on the display screen 5. At this time, the flow meter 13 in the inlet pipe 12 measures the flow rate of the liquid in real time and feeds it back to the circuit board 11. The circuit board 11 sends a command to the micro-control valve 14 based on these data. The micro-control valve 14 precisely adjusts the valve opening to control the liquid to flow from the outer material chamber 3 into the inner material chamber 2 through the inlet pipe 12. The liquid entering the inner material chamber 2 is converted into tiny droplets by the atomizing plate 4 on the side, which works based on the ultrasonic principle. The droplets are then sprayed out through the through hole 15 on the side of the outer shell 1, which corresponds to the position of the atomizing plate 4, thus completing the eye nebulization drug administration. After the drug administration is completed and the drug effect is fully exerted, the three vision chart lenses 7, which are equidistantly arranged in the lens chamber 6, are used to test vision from different distances. The eye focusing lens 8 located at the bottom of the vision chart lens 7 assists the user in focusing, thereby judging whether the vision is clear. This allows for a quick and accurate judgment of whether the drug has taken effect and whether the vision has improved. Specific Implementation Example 2:

[0030] A micro-upgraded precision-controlled electronic nebulizer for eye administration, based on the basic structure in Specific Embodiment 1, further discloses the following: a communication module is added to the circuit board 11, which connects to a mobile phone or computer via Bluetooth or Wi-Fi, and synchronizes data such as each administration dose and vision test results to the relevant application for data analysis, generating a curve of the user's eye health status change, providing doctors or users with a more intuitive reference.

[0031] In summary:

[0032] 1. The device employs a lens compartment 6, an eye focusing lens 8, and a vision chart lens 7. After the user completes the ocular nebulization medication, they can directly use the three vision chart lenses 7, which are equidistantly arranged in the lens compartment 6 at the bottom of the device, to test their vision from different distances to determine whether their vision is clear. The eye focusing lens 8 is located at the bottom of the vision chart lens 7, which helps the user to better focus on the vision chart, making the test results more accurate. This integrated design allows the user to quickly and accurately determine whether the medication has taken effect and whether their vision has improved after administration, thus facilitating timely adjustments to the treatment plan based on the actual situation, greatly improving the effectiveness and targeting of ocular medication treatment.

[0033] 2. The system employs an inlet pipe 12, a flow meter 13, and a micro-control valve 14. The inlet pipe 12 serves as the drug delivery channel, and the flow meter 13 inside it can accurately measure the drug flow rate in real time and feed the data back to the circuit board 11. The micro-control valve 14 receives the instructions issued by the circuit board 11 based on the data from the flow meter 13 and precisely adjusts the valve opening. During drug administration, according to the preset dosage, a certain amount of drug can enter the atomization area of ​​the inner material chamber 2 through the close cooperation of the flow meter 13 and the micro-control valve 14, thereby achieving precise control of the drug delivery volume. This avoids the problem of drug deviation caused by the inability to accurately control the dosage in traditional drug administration methods, reduces the risk of insufficient dosage affecting the treatment effect or excessive dosage causing adverse reactions, and greatly improves the safety and effectiveness of ocular drug delivery therapy.
