Description

Technical Field

[0001] This utility model relates to the field of eye nebulizer technology, specifically an electronic eye nebulizer for administering viscous medications. Background Technology

[0002] Some people do not pay attention to eye hygiene, which can easily lead to eye diseases, eye fatigue, and dry eyes. Therefore, people use eye drops to relieve eye fatigue and dry eyes and reduce the probability of eye diseases.

[0003] Chinese patent CN215020335U discloses an eye nebulizer that atomizes medication through an atomizing plate and sprays it into the eyes to achieve a soothing effect. It uses a glass bottle and sterile container for packaging. The sealed glass bottle is used by breaking the silicone cap of the glass bottle to allow the liquid to flow out. This makes the eye nebulizer product more sterile and convenient for consumers to use, and it is worth promoting.

[0004] The above-mentioned solution uses gravity to drip the liquid medicine filled in the glass bottle onto the nebulizer for atomization. This method of adding medicine is only suitable for highly fluid liquids. However, some viscous liquids, due to their poor flowability, are difficult to drip effectively from the bottle, making it difficult to accurately control the atomization volume. Therefore, we provide an ophthalmic electronic nebulizer designed for viscous liquids to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: an electronic nebulizer for eye medication adapted to viscous liquids, including a medication body 1 and a liquid delivery device. The medication body 1 is provided with a liquid delivery tube 2 and a receiving cavity 3, and the liquid delivery tube 2 is connected to the receiving cavity 3 and the liquid delivery tube 2 is connected to the nebulization cavity.

[0030] The liquid delivery device includes a needle tube 8 that matches the receiving cavity 3. A piston 10 is slidably connected inside the needle tube 8. A drain pipe 9 is fixedly connected to the bottom end of the needle tube 8. A push-pull rod 12 is fixedly connected to the piston 10.

[0031] Before administering the liquid, the drain tube 9 on the syringe 8 needs to be aligned with the medicine bottle containing the liquid. The piston 10 is moved inside the syringe 8 by the push-pull rod 12 to draw the viscous liquid into the syringe 8 through the drain tube 9. When administering the liquid, the syringe 8 needs to be inserted into the receiving cavity 3 and the drain tube 9 needs to be inserted into the delivery tube 2. The viscous liquid is then injected into the nebulization chamber through the drain tube 9.

[0032] A guide plate 11 is fixedly connected to the syringe 8, and a push-pull rod 12 is slidably connected to the middle of the guide plate 11. The guide plate 11 limits the piston 10 and guides the push-pull rod 12. A handle 13 is fixedly connected to the syringe 8, and a placement groove 4 matching the handle 13 is provided on the drug delivery device 1. The handle 13 makes it easy to hold the syringe 8, and the placement groove 4 can store the handle 13.

An electric push rod 7 is installed inside the control box 6, and the telescopic end of the electric push rod 7 passes through the control box 6 and extends to the outside of the control box 6.

[0034] When it is necessary to inject viscous medicine into the nebulizer, the telescopic end of the electric push rod 7 extends quantitatively to push the push-pull rod 12, thereby completing the precise delivery of viscous medicine. The control box 6 can also rotate above the drug delivery device 1 via the support rod 5, which facilitates the loading and unloading of the delivery device.

[0035] The first limiting component is disposed on the drug delivery device body 1 and is used to limit and fix the control box 6. The first limiting component includes an adjustment groove 14 opened on the drug delivery device body 1 and a limiting sleeve 16 fixedly connected to the control box 6. A limiting screw 15 is disposed in the adjustment groove 14. One end of the limiting screw 15 passes through the drug delivery device body 1 and is inserted into the limiting sleeve 16. The limiting screw 15 is threadedly connected to the drug delivery device body 1.

[0036] When the control box 6 is rotated above the drug delivery device 1, the limiting screw 15 is rotated and inserted into the limiting sleeve 16 in a spiral upward state, thereby limiting the control box 6.

[0037] The second limiting component is disposed on the drug delivery device body 1 and is used to limit and fix the needle tube 8 placed in the receiving cavity 3. The second limiting component includes two sets of adjustment boxes 17 fixedly connected to the drug delivery device body 1. Each adjustment box 17 is provided with a moving groove 18. Each moving groove 18 is slidably connected with a limiting plate 19. One end of the limiting plate 19 is located above the needle tube 8, and the other end of the limiting plate 19 is fixedly connected to a holding plate 20.

[0038] The limiting plate 19 can be pushed to slide within the moving groove 18 by holding the plate 20, and the limiting plate 19 can be positioned above the handle 13 to limit the liquid dispenser.
