Description

Technical Field

[0001] This invention relates to the field of ophthalmic equipment technology, and in particular to an atomizing ophthalmic drug delivery device. Background Technology

[0002] Atomized ophthalmic drug delivery devices are medical devices that use atomization technology to transform liquid ophthalmic medications into tiny droplets, allowing the medication to act directly on the ocular surface or intraocular target tissues in aerosol form. However, existing ophthalmic atomization devices have key drawbacks regarding unilateral atomization treatment and drug residue: traditional dual-cavity eye masks cause cross-diffusion of the drug mist due to airflow connectivity, passively exposing the healthy eye to the medication and increasing the risk of complications; symmetrical flow field design significantly reduces the actual amount of medication received by the affected eye, affecting the treatment effect in one eye. Simultaneously, a large amount of drug residue remains in the eye mask, and the residual liquid is wasted due to secondary atomization failure. Summary of the Invention

[0003] The main objective of this invention is to provide an atomizing ophthalmic drug delivery device that can effectively solve the problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The atomizing goggle has a circular groove. A fog outlet cover is fixedly installed on the inner wall of the atomizing goggle corresponding to the position of the circular groove. A fixing tube is fixedly installed on the fog outlet cover near one end of the circular groove. A fixing ring is fixedly installed on one end of the obtuse-angled groove corresponding to the position of the circular groove.

Several sets of shielding leaves are rotatably installed between the fixing ring and the fixing tube. A column gear is fixedly installed on one end of the outer side of each set of shielding leaves. An elastic strip is fixedly installed between the outer side of the first toothed ring and the inner wall of one side of the obtuse-angled groove.

[0006] Preferably, the control component includes two sets of fixed shafts fixedly mounted on the inner walls of two sets of obtuse-angled grooves. A non-standard rack is movably mounted on the outer side of each of the two sets of fixed shafts. A spring is fixedly mounted on the slope of each of the two sets of non-standard racks. Two sets of connecting shafts are fixedly mounted on the upper side of each of the two sets of springs. A U-shaped piece is fixedly mounted at one end of each of the two sets of non-standard racks. A partition is fixedly mounted in the middle cavity of the inner shell. A motor is fixedly mounted on the upper end of the partition. A fixed plate is fixedly mounted in the middle cavity of the inner shell. Two sets of ratchet wheels are movably mounted on the inner side of the fixed plate. An annular groove is formed on the outer shell of each of the two sets of ratchet wheels. A second toothed ring is fixedly mounted on the outer shell of one set of ratchet wheels facing the non-standard rack. A top block is fixedly mounted on the outer shell of the other set of ratchet wheels.

[0007] Preferably, the collection assembly includes a right-angle rod rotatably disposed in a fixed tube, a crossbar fixedly disposed at the upper end of the right-angle rod, a film fixedly disposed at the upper end of the crossbar, a fan fixedly disposed at the end of the right-angle rod near the fixed ring, two sets of connecting tubes fixedly disposed at the lower end of the atomizing goggles, a collection port being provided at the connection points of the two sets of connecting tubes on the lower side of the atomizing goggles, a connector being fixedly disposed between the two sets of connecting tubes, and a collection bottle being threadedly connected to the lower side of the connector.

[0008] Preferably, the corrugated pipe communicates with the drug inlet, the circular groove, and the interior of the atomizing goggle, and the first toothed ring is meshed with several sets of spur gears.

[0009] Preferably, several groups of the shielding leaves are uniformly formed into a circular structure, and the shielding leaves rotate along the connection of the fixed tube.

[0010] Preferably, the outer side of the irregular rack is provided with two tooth blocks, one side of the irregular rack is engaged with the arc-shaped rack, the other side of the irregular rack is engaged with the second tooth ring, the irregular rack is slidably disposed with the fixed shaft and the connecting shaft, and the connecting shaft is inserted into the inner side of the irregular rack.

[0011] Preferably, the U-shaped piece corresponds to the rotation trajectory of the top block, the motor rotation shaft is fixedly connected to the drive hexagonal wheel on the inner side of the two sets of ratchet wheels, the damping of the fixing plate is set on the outer side of the two sets of annular grooves, and the drive structures of the two sets of ratchet wheels are opposite.

[0012] Preferably, the film is attached to the inner wall of the atomizing goggle, the fan is correspondingly disposed in the adjustment assembly, and the collection port is connected to the inside of the atomizing goggle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Turn on the existing nebulizer to atomize the medication and enter the nebulizer goggles for application to the patient's eyes. When applying medication to both eyes according to the patient's needs, turn on the motor to rotate counterclockwise. At this time, the motor shaft drives a set of ratchet wheels connected to the outside to rotate, thereby causing the two sets of dissimilar racks to move synchronously along the connecting shaft and the fixed shaft. This opens or closes the two sets of adjustment components, enabling simultaneous nebulization of medication to both eyes.

[0015] 2. When nebulization is required for one eye, the motor shaft rotates clockwise to drive the ratchet connected to the top block to rotate, while the second toothed ring remains stationary. This causes the top block to rotate 90 degrees, which lifts and supports the upper U-shaped plate and the irregular toothed rack. With the elastic action of the spring, the irregular toothed rack disengages from the second toothed ring. At this point, rotating counterclockwise will drive the other side of the irregular toothed rack to move through the second toothed ring, thus opening the corresponding single set of adjustment components. When only the other set of adjustment components needs to be opened, rotating 270 degrees clockwise will push the other set of irregular toothed racks to disengage from the second toothed ring, thereby completing different methods of drug delivery to better meet the needs of patients.

[0016] 3. While the heterogeneous rack moves, the driven meshing arc-shaped rack and the first gear ring rotate outside the fixed ring, simultaneously stretching the elastic strip. Then, through the rotating first gear ring, several sets of meshing spur gears are driven to rotate 90 degrees, evenly opening the shielding leaves connected by several sets of spur gears. After rotating 90 degrees, the shielding leaves can directly discharge the atomized medicine into the atomizing goggles for medication. When the shielding leaves are driven to rotate slightly, they are in an inclined open state, and the medicine is discharged in a spiral, forming a vortex barrier that resists environmental interference, relatively reducing the blind spot for drug delivery and realizing different drug delivery methods.

[0017] 4. During the atomized application of the medicine, the atomized airflow will drive the fan and the right-angle rod to rotate, and together with the crossbar, it will drive the film to scrape off the condensed medicine droplets on the inner wall. The droplets will then be collected in the collection bottle through the collection port and connecting tube, reducing unnecessary medicine waste. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate relative orientations or positional relationships and are only used to facilitate the description of this invention and simplify 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 of this invention.

[0032] Please see Figures 1-11 This invention provides an embodiment of an ophthalmic drug delivery device, comprising a nebulizer 1, a corrugated tube 2 fixedly mounted on the nebulizer 1, a nebulizing goggle 3 fixedly mounted on the upper side of the corrugated tube 2, two sets of drug inlet holes 4 on one side of the nebulizing goggle 3, an adjustment component 5 mounted on the inner side of the nebulizing goggle 3, a control component 6 disposed on the inner side of the adjustment component 5, and two sets of collection components 7 disposed on the inner and lower sides of the nebulizing goggle 3. The adjustment component 5 includes an inner shell 51 fixedly mounted on the inner wall of one side of the nebulizing goggle 3, two sets of obtuse-angled grooves 52 disposed on the inner side of the inner shell 51, and a circular groove 53 disposed on the inner side of the obtuse-angled grooves 52. A fogging cover 54 is fixedly installed on the inner wall of the atomizing goggle 3 at the position corresponding to the circular groove 53. A fixing tube 55 is fixedly installed on the end of the fogging cover 54 near the circular groove 53. A fixing ring 56 is fixedly installed on one end of the obtuse angle groove 52 at the position corresponding to the circular groove 53. A first toothed ring 57 is rotatably installed on the outside of the fixing ring 56. An arc-shaped rack 58 is fixedly installed on the upper end of the first toothed ring 57. Several sets of shielding leaves 59 are rotatably installed between the fixing ring 56 and the fixing tube 55. A column gear 510 is fixedly installed on one side of each set of shielding leaves 59. An elastic strip 511 is fixedly installed between the outside of the first toothed ring 57 and the inner wall of one side of the obtuse angle groove 52.

[0033] The corrugated pipe 2 is connected to the inside of the inlet hole 4, the circular groove 53, and the atomizing goggle 3. The first toothed ring 57 is meshed with several sets of cylindrical gears 510. Several sets of shielding leaves 59 are uniformly formed into a circular structure. The shielding leaves 59 rotate along the connection of the fixed pipe 55.

[0034] While the heterogeneous rack 62 moves, the driven meshing arc-shaped rack 58 and the first toothed ring 57 rotate outside the fixed ring 56, simultaneously stretching the elastic strip 511. Then, through the rotating first toothed ring 57, several sets of meshing spur gears 510 are driven to rotate 90 degrees, evenly opening the shielding leaves 59 connected to the several sets of spur gears 510. After rotating 90 degrees, the shielding leaves 59 can directly discharge the atomized medicine into the atomizing goggles 3 for drug administration. When the several sets of shielding leaves 59 are driven to rotate slightly, the shielding leaves 59 are in an inclined open state, and the medicine is discharged in a spiral, forming a vortex barrier that resists environmental interference, relatively reducing the drug administration blind zone and realizing different drug administration methods.

[0035] The control component 6 includes two sets of fixed shafts 61 fixedly mounted on the inner walls of two sets of obtuse-angled grooves 52. Different-shaped racks 62 are movably mounted on the outer sides of both sets of fixed shafts 61. Spring pieces 63 are fixedly mounted on the slopes of both sets of different-shaped racks 62. Two sets of connecting shafts 64 are fixedly mounted on the upper sides of both sets of spring pieces 63. A U-shaped piece 65 is fixedly mounted at one end of each set of different-shaped racks 62. A partition 66 is fixedly mounted in the middle cavity of the inner shell 51. A motor 67 is fixedly mounted on the upper end of the partition 66. A fixed plate 68 is fixedly mounted in the middle cavity of the inner shell 51. Two sets of ratchet wheels 69 are movably mounted inside the fixed plate 68. An annular groove 610 is opened on the outer shell of each set of ratchet wheels 69. A second toothed ring 611 is fixedly mounted on the outer shell of one set of ratchet wheels 69 that faces the different-shaped racks 62. A top block 612 is fixedly mounted on the outer shell of the other set of ratchet wheels 69.

[0036] Two toothed blocks are provided on the outer side of the irregular rack 62. One side of the irregular rack 62 is engaged with the arc-shaped rack 58, and the other side of the irregular rack 62 is engaged with the second toothed ring 611. The irregular rack 62 is slidably connected to the fixed shaft 61 and the connecting shaft 64. The connecting shaft 64 is inserted into the inner side of the irregular rack 62. The U-shaped piece 65 corresponds to the rotation trajectory of the top block 612. The rotating shaft of the motor 67 is fixedly connected to the driving hexagonal wheel on the inner side of the two sets of ratchet 69. The damping of the fixed plate 68 is provided on the outer side of the two sets of annular grooves 610. The driving structures of the two sets of ratchet 69 are opposite.

[0037] Turn on the existing nebulizer 1 to atomize the medication and deliver it into the nebulizer goggles 3 for application to the patient's eyes. When applying medication to both eyes as needed, the motor 67 rotates counter-clockwise. This causes the ratchet 69 and the outer second toothed ring 611 to rotate, synchronously moving the two sets of dissimilar racks 62 along the connecting shaft 64 and the fixed shaft 61. This opens or closes the two sets of adjusting components 5, allowing for simultaneous nebulization of both eyes. When nebulization is needed for only one eye, the motor 67 rotates clockwise, driving the top... When the ratchet 69 connected to block 612 rotates while the second toothed ring 611 remains stationary, the top block 612 rotates 90 degrees, which lifts and supports the upper U-shaped plate 65 and the heterogeneous rack 62. With the elastic action of the spring plate 63, the heterogeneous rack 62 disengages from the second toothed ring 611. At this time, counterclockwise rotation can drive the other heterogeneous rack 62 to move through the second toothed ring 611, thus opening the corresponding single set of adjustment components 5. When only the other set of adjustment components 5 needs to be opened, it can be rotated 270 degrees clockwise to push the other set of heterogeneous racks 62 to disengage from the second toothed ring 611, thereby completing different methods of drug administration and meeting the better needs of patients.

[0038] The collection component 7 includes a right-angle rod 71 rotatably mounted in the fixed tube 55, a crossbar 72 fixedly mounted on the upper end of the right-angle rod 71, a film 73 fixedly mounted on the upper end of the crossbar 72, a fan 74 fixedly mounted on the end of the right-angle rod 71 near the fixed ring 56, two sets of connecting tubes 75 fixedly mounted on the lower end of the atomizing goggles 3, and collection ports 76 are opened at the connection points of the two sets of connecting tubes 75 on the lower side of the atomizing goggles 3, a connector 77 is fixedly mounted between the two sets of connecting tubes 75, and a collection bottle 78 is threadedly connected to the lower side of the connector 77.

[0039] The film 73 is attached to the inner wall of the atomizing goggle 3, the fan 74 is correspondingly set in the adjustment component 5, and the collection port 76 is connected to the inside of the atomizing goggle 3.

[0040] During the atomized drug application process, the atomized airflow will drive the fan 74 and the right-angle rod 71 to rotate, and together with the crossbar 72, it will drive the film 73 to scrape off the drug droplets that have condensed on the inner wall. The droplets are then discharged into the collection bottle 78 through the collection port 76 and the connecting tube 75 for collection, reducing unnecessary drug waste.

[0041] Working principle: In use, the existing nebulizer 1 is turned on, allowing the medication to be atomized and enter the nebulizer goggles 3 for application to the patient's eyes. When applying medication to both eyes according to the patient's needs, the motor 67 is turned on and rotates counterclockwise. At this time, the rotating shaft of the motor 67 drives a set of ratchet 69 connected to the outer second toothed ring 611 to rotate, thereby causing the two sets of dissimilar toothed racks 62 to move synchronously along the connecting shaft 64 and the fixed shaft 61, opening or closing the two sets of adjusting components 5 respectively, so as to achieve simultaneous nebulizer application to both eyes. When the device needs to perform nebulization application with one eye, the motor 67 rotates clockwise to drive the ratchet 69 connected to the top block 612 to rotate, while the second gear ring 611 remains stationary. This causes the top block 612 to rotate 90 degrees, which lifts and supports the upper U-shaped plate 65 and the irregular rack 62. With the elastic action of the spring plate 63, the irregular rack 62 disengages from the second gear ring 611. At this time, counterclockwise rotation will drive the other side of the irregular rack 62 to move through the second gear ring 611, thus opening the corresponding single set of adjustment components 5. When only the other set of adjustment components 5 needs to be opened, clockwise rotation is sufficient. Rotating 270 degrees pushes another set of heterogeneous racks 62 to disengage from the second toothed ring 611, thereby completing different methods of drug delivery to better meet the patient's needs. Additionally, while the heterogeneous racks 62 move, they drive the meshing arc-shaped racks 58 and the first toothed ring 57 to rotate outside the fixed ring 56, simultaneously stretching the elastic strip 511. The rotating first toothed ring 57 then drives several sets of meshing spur gears 510 to rotate 90 degrees, evenly opening the shielding leaves 59 connected to the spur gears 510. The shielding leaves 59, after rotating 90 degrees, can then atomize the medication. The medication is directly discharged into the atomizing goggles 3 for administration. When the atomizing blades 59 rotate slightly, they are tilted and open, and the medication is discharged in a spiral, forming a vortex barrier that resists environmental interference, reducing the blind spot for medication administration and enabling different administration methods. Finally, during the atomization process, the atomizing airflow drives the fan 74 and the right-angle rod 71 to rotate, which, together with the crossbar 72, drives the film 73 to scrape off the condensed drug droplets on the inner wall. The drug is then discharged into the collection bottle 78 through the collection port 76 and the connecting tube 75 for collection, reducing unnecessary drug waste.

[0042] The atomizing sprayer 1, corrugated pipe 2, atomizing goggles 3, motor 67, and ratchet 69 in this invention are common knowledge in the field, and their working principles are well-known technologies. The appropriate model is selected according to actual use, so they will not be explained in detail.
