Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, in particular to a portable eye medication dispenser based on vibrating screen atomization technology. Background Art

[0002] As the pace of modern society accelerates, people face increasing pressure from studying and working, leading to longer work and study hours and, in turn, a growing number of eye diseases. Young people, in particular, often experience eye problems, visual fatigue, and dry eyes due to neglecting eye hygiene. To alleviate these symptoms and reduce the risk of eye disease, many people turn to eye drops.

[0003] Currently, there are two main ways to use eye drops. The first is to drip directly into the eye, but this method may cause fear in the user, affecting the drug's effectiveness, and requires precise control of the dripping position. Otherwise, it is difficult to ensure that the drug effectively enters the eye, resulting in poor results. The second method is to use an atomizer to atomize the eye drops and then administer them to the eye. Compared with direct dripping, this method is gentler, more precise, and can effectively achieve ocular drug delivery, and therefore has been widely praised by users.

[0004] After extensive searching, the publication number is CN111905203A, which discloses an eye protection atomizer, comprising a liquid storage bottle and an eye wash cup; a liquid dispenser is provided on the liquid storage bottle; the eye wash cup can be fixedly connected to the liquid dispenser when washing the eyes; and the eye wash cup can be buckled on the liquid dispenser when not washing the eyes.

[0005] In the existing technology, when the device is in use, the eyewash cup can be clipped onto the liquid dispenser or buckled onto the liquid dispenser, making it more convenient to carry and reusable. Moreover, after disinfection, the eyewash cup can be directly buckled onto the liquid dispenser to drain water faster and prevent bacterial growth.

[0006] However, after market research, it was found that the residual amount of spray atomization of this type of jet nebulizer can reach 0.5-1ml, which results in a large amount of drug waste. At the same time, the actual dosage used by the patient is not enough, which can easily affect the treatment effect. In addition, the jet nebulizer can only atomize small molecule drug solutions and is prone to clogging during use. At the same time, it is inconvenient for the jet nebulizer to control the flow rate of the drug solution when administering the solution, resulting in insufficient atomization. Therefore, a portable eye drug delivery device based on vibrating screen atomization technology is proposed to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a portable ophthalmic drug delivery device based on a vibrating screen atomization technology, which can effectively solve the problems of easy clogging of the jet atomizer and inconvenience in controlling the flow rate of the drug solution in the background technology.

The bottom of the liquid inlet bin passes through the bottom of the bottom shell and is connected to a connecting sleeve. The connecting sleeve is threadedly installed with the top of the medicine tank, and a duckbill valve is embedded in the connecting sleeve.

[0011] Extrusion blocks are rotatably installed on both sides of the top shell. The cross sections of the two extrusion blocks are designed with a triangular structure. The outer walls of the two extrusion blocks on the opposite side are always in contact with the outer wall of the liquid inlet bin but are not fixedly connected.

[0012] Preferably, a medicine placement slot that matches the size of the rehydration tank is provided on one side of the upper end surface of the battery box, and a charging slot that matches the size of the applicator body is provided on the other side of the upper end surface of the battery box.

Since there is no need to place a large battery in the applicator, the size of the applicator can be made smaller, which is convenient for carrying and operation.

The setting of the ultraviolet disinfection lamp can disinfect the applicator body when it is stored.

[0019] By adopting the above technical solution, the bearing and nut column design on the top of the inner wall of the top shell allows the micro motor to be compactly installed in the atomizer assembly, saving space. The micro motor is fixed by the nut column, which enhances the stability of the structure and reduces vibration during operation.

[0020] Preferably, the micro motor is electrically connected to the battery assembly, the micro motor is transmission-mounted on the bottom of the extrusion block, and the top of the extrusion block is limitedly mounted on both sides of the interior of the top shell by bearings.

[0021] By adopting the above technical solution, the micro motor is electrically connected to the battery assembly, ensuring efficient transmission of electricity and reducing energy loss.

[0023] By adopting the above technical solution, the piezoelectric ceramic component is electrically connected to the battery component and controlled by the start switch, which simplifies the operation process.

[0024] Preferably, an inspection port is provided on the back of the liquid inlet bin, the back of the top shell is opened at a position corresponding to the inspection port and an inspection cover is movably installed, and a liquid outlet is provided on the front of the liquid inlet bin, and the position of the liquid outlet matches the position of the opening on the front of the top shell.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention reduces drug residue and clogging risk by installing a screen on the piezoelectric ceramic assembly, effectively improving drug utilization and atomization efficiency. The size and distribution of these screens are precisely calculated and designed to ensure that the drug solution is evenly atomized in the form of fine droplets, thereby improving drug delivery efficiency and absorption rate. Precise control of the screens allows the drug solution to be almost completely converted into atomized form, significantly reducing drug residue during the drug administration process. This design is particularly suitable for expensive eye drops, effectively reducing cost. Because the screen size is much smaller than the nozzle of a traditional jet atomizer, it is less susceptible to clogging by impurities in the drug solution or viscosity changes. This is particularly important for eye drops containing large molecular weight drugs, as these drugs are more likely to cause clogging in traditional atomizers. The uniform distribution of the drug solution and the formation of fine droplets during atomization ensure that the drug reaches the ocular tissue more effectively, improving drug bioavailability. This is particularly important for eye drops that require precise dosage control. The screen design makes the atomization process more gentle, reduces physical damage to the drug solution, and maintains drug activity. At the same time, due to the uniformity of the atomization process, the distribution of the drug is more uniform, which improves the therapeutic effect. When facing liquid medicines of different viscosities, traditional jet nebulizers need to adjust the injection pressure, which may lead to unstable atomization effect. The screen design of the present invention is not affected by the viscosity of the liquid medicine, and provides a stable atomization effect. The screen design in the piezoelectric ceramic component enables the present invention to adapt to various types of eye drops. Whether it is water-soluble or oil-soluble drugs, they can be effectively administered through this atomization method. When using, the user only needs to turn on the switch and the piezoelectric ceramic component will start working. No complicated operation or adjustment is required, making the drug administration process simpler and faster. Due to the reduction of liquid medicine residue, it helps to reduce drug waste and meets the requirements of environmental protection and economy. This is especially important when the cost of drugs is high. This design avoids the problem of blockage caused by changes in liquid medicine viscosity or impurities in traditional jet nebulizers due to high-speed airflow or liquid injection.

[0028] The present invention achieves the effect of precisely controlling the flow rate of the drug solution by providing a sponge block that is movably placed in the liquid inlet chamber and extrusion blocks controlled by micro motors on both sides, thereby ensuring the uniformity and continuity of the atomization process. This design replaces the difficult-to-control flow rate of the drug solution in traditional jet nebulizers, providing a more precise and stable atomization effect. The liquid inlet chamber is designed with a high-toughness material, which facilitates the extrusion block to perform extrusion, thereby effectively prompting the sponge block to absorb the drug solution and transport it to the piezoelectric ceramic component. The choice of this high-toughness material not only reduces the adhesion of the drug solution during the atomization process, but also, due to its good elasticity and recovery ability, enables the extrusion block to extrude the sponge block more efficiently. The high-toughness material used in the liquid inlet chamber has good elasticity and deformation resistance, and can withstand repeated pressure during the movement of the extrusion block without permanent deformation. When the extrusion block rotates under the control of the motor, its triangular structure design makes the extrusion more concentrated and effective. The squeezing action of the squeezing block on the sponge block enables the sponge block to quickly absorb the medicine liquid, and under the squeezing action, the medicine liquid is transported from the liquid inlet tank through the connecting sleeve to the piezoelectric ceramic component. The sponge block is effectively squeezed in the liquid inlet tank made of high-toughness material, ensuring that the medicine liquid can be transported to the piezoelectric ceramic component in a more uniform and continuous manner, thereby improving the atomization efficiency and treatment effect.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figures 1 to 8 As shown, the present invention provides an embodiment: a portable ophthalmic drug delivery device based on vibrating screen atomization technology, including a battery box 1, a cover body 2 is rotatably mounted on the top of the battery box 1, a drug delivery device body 3 and a fluid replacement tank 4 are movably placed in the battery box 1, the drug delivery device body 3 includes an atomization assembly 33, a battery assembly 32 is fixedly sleeved on the bottom of the atomization assembly 33, a liquid medicine tank 31 is movably mounted on the bottom of the battery assembly 32, and the top of the liquid medicine tank 31 passes through the battery assembly 32 and is connected to the atomization assembly 33;

[0041] The atomizing assembly 33 includes a top shell 331 and a bottom shell 332. The top shell 331 has an opening on the front and is fixed with an atomizing groove 3315. The atomizing groove 3315 is embedded with a piezoelectric ceramic assembly 335.

[0042] A liquid inlet tank 333 is embedded in the bottom shell 332. The liquid inlet tank 333 is made of low-density polyethylene. A sponge block 334 is movably placed in the liquid inlet tank 333. The bottom of the liquid inlet tank 333 passes through the bottom of the bottom shell 332 and is connected to a connecting sleeve 3321. The connecting sleeve 3321 is threadedly installed on the top of the medicine tank 31. A duckbill valve 3322 is embedded in the connecting sleeve 3321.

[0043] Extrusion blocks 3311 are rotatably installed on both sides of the top shell 331. The cross-sections of the two extrusion blocks 3311 are both triangular in structure. The outer walls of the opposite sides of the two extrusion blocks 3311 are always in contact with the outer wall of the liquid inlet tank 333 but are not fixedly connected.

[0044] Specifically, by providing a mesh 3355 on the piezoelectric ceramic assembly 335, the effect of reducing drug residue and the risk of clogging is achieved, effectively improving drug utilization and atomization efficiency. The size and distribution of these meshes 3355 are precisely calculated and designed to ensure that the drug solution is evenly atomized in the form of fine droplets, thereby improving drug delivery efficiency and absorption rate. The precise control of the mesh 3355 allows the drug solution to be almost completely converted into atomized form, greatly reducing drug residue during the drug administration process. This design is particularly suitable for eye drops with higher unit prices, effectively reducing cost waste. Because the size of the mesh 3355 is much smaller than that of the nozzle of a traditional jet atomizer, it is less likely to be clogged by impurities in the drug solution or viscosity changes. This is particularly important for eye drops containing large molecular drugs, as these drugs are more likely to cause clogging in traditional atomizers. The uniform distribution of the drug solution and the formation of fine droplets during atomization allow the drug to more effectively contact the ocular tissue, thereby improving the drug's bioavailability. This is particularly important for eye drops that require precise dosage control. The screen 3355 design makes the atomization process gentler, reduces physical damage to the liquid medicine, and maintains the activity of the drug. At the same time, due to the uniformity of the atomization process, the distribution of the drug is more uniform, improving the therapeutic effect. Traditional jet nebulizers need to adjust the injection pressure when facing liquid medicines of different viscosities, which may lead to unstable atomization effect. The screen 3355 design of the present invention is not affected by the viscosity of the liquid medicine and provides a stable atomization effect. The screen 3355 design within the piezoelectric ceramic assembly 335 makes the present invention adaptable to various types of eye drops. Whether it is water-soluble or oil-soluble drugs, they can be effectively administered through this atomization method. When using, the user only needs to activate the switch 3313, and the piezoelectric ceramic assembly 335 will start working without complicated operations or adjustments, making the drug administration process simpler and faster. Due to the reduction of liquid medicine residue, it helps to reduce drug waste, meeting the requirements of environmental protection and economy. This is particularly important when the cost of drugs is high. This design avoids the problem of clogging caused by changes in the viscosity of the drug solution or impurities in traditional jet nebulizers due to high-speed airflow or liquid injection.

[0045] By providing a sponge block 334 movably positioned within the liquid inlet chamber 333 and extrusion blocks 3311 on either side, controlled by micro-motors 3312, the flow rate of the drug solution is precisely controlled, ensuring uniformity and continuity during the atomization process. This design replaces the difficult-to-control flow rate of the drug solution in traditional jet nebulizers, providing a more precise and stable atomization effect. Furthermore, the liquid inlet chamber 333 is constructed of a highly ductile material, facilitating the extrusion block 3311's extrusion, effectively encouraging the sponge block 334 to absorb the drug solution and deliver it to the piezoelectric ceramic assembly 335. This highly ductile material not only reduces drug adhesion during atomization, but also, due to its excellent elasticity and resilience, allows the extrusion block 3311 to more efficiently compress the sponge block 334. The highly ductile material used in the liquid inlet chamber 333 exhibits excellent elasticity and deformation resistance, allowing it to withstand repeated pressure during the movement of the extrusion block 3311 without permanent deformation. As the extrusion block 3311 rotates under the control of the motor, its triangular structure ensures more concentrated and effective extrusion. The squeezing action of the squeezing block 3311 on the sponge block 334 enables the sponge block 334 to quickly absorb the medicine liquid, and under the squeezing action, the medicine liquid is transported from the liquid inlet tank 333 to the piezoelectric ceramic component 335 through the connecting sleeve 3321. The sponge block 334 is effectively squeezed in the liquid inlet tank 333 made of high-toughness material, ensuring that the medicine liquid can be transported to the piezoelectric ceramic component 335 in a more uniform and continuous manner, thereby improving the atomization efficiency and treatment effect.

[0050] Specifically, the limiting groove design on the lower end surface of the cover body 2 ensures that the rehydration tank 4 and the applicator body 3 are firmly placed in the battery box 1 to prevent displacement during use and carrying.
