Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary products technology, specifically to an auxiliary device for precise instillation of eye drops. Background Technology

[0002] In hospitals, patients often need to use eye drops for the treatment of eye diseases. For example, eye infections (such as bacterial conjunctivitis and keratitis) require antibiotic eye drops to control inflammation; after ophthalmic surgery (such as cataract and glaucoma surgery), anti-inflammatory and antibacterial eye drops are often needed to prevent infection and promote recovery.

[0003] Currently, manual instillation of eye drops is commonly used. The procedure involves the user tilting their head back to a suitable angle, using the fingers of the non-bottle hand to open the upper and lower eyelids to fully expose the conjunctival sac, and then holding the eye drop bottle with the nozzle facing the eyeball, squeezing the bottle to accurately drip the solution onto the eye surface. However, this traditional method has problems. Some patients, due to trembling hands, inaccurate distance judgment, or lack of skill, cannot accurately instill the solution into the eye, affecting the treatment effect. Furthermore, because the operator needs to directly contact the eyelids and eyelashes, bacteria carried on the fingers can easily spread through contact, leading to eye infections.

[0004] Therefore, how to design an eye drop precision instillation auxiliary device that can accurately instill medication and avoid causing eye infections is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects in the prior art where some patients cannot accurately drip eye drops into their eyes due to hand tremors, inaccurate positioning, or unfamiliarity with the operation, thus affecting the efficacy; and the technical defects in the prior art where fingers touching the eyelids and eyelashes can easily introduce bacteria and cause infection when manually dripping eye drops. Therefore, this invention provides an eye drop precision dripping auxiliary device that can accurately drip eye drops into the eyeball and avoid causing eye infection and damage.

[0028] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0029] This embodiment provides an auxiliary device for precise instillation of eye drops, such as... Figure 1-5As shown, it includes: a main body 1, a medicine bottle placement cylinder 2, a limiting structure, a first extrusion plate 4, and a second extrusion plate 5; wherein, the main body 1 has an inner cavity 11, the inner cavity 11 having a bottom opening, the end of the bottom opening being adapted to rest against the contour of the eye socket; the medicine bottle placement cylinder 2 is disposed within the inner cavity 11, having a mounting cavity 21 adapted to hold a medicine bottle 3, the mounting cavity 21 having a top opening, and a bottom plate 22 having a bottom plate 22 having a drip opening 23 communicating with the mounting cavity 21 in the middle; the top of the medicine bottle placement cylinder 2 is integrally formed with the top of the main body 1. The connection is type-shaped; the limiting structure is used to limit the medicine bottle 3 within the mounting cavity 21; the first extrusion plate 4 is bent with both ends curving outwards, and is movably mounted in the middle on one side of the main body 1. A first extrusion post 7 is provided at the top, and a first expansion plate 41 is formed at the bottom.

A second extrusion post 71 is provided at the top, and a second expansion plate 51 is formed at the bottom. The second support plate 51 is flush with the bottom opening and extends inward into the inner cavity 11; the main body 1 has a first main opening 72 opposite to the first extrusion column 7, and the medicine bottle placement cylinder 2 has a first extrusion opening 74 opposite to the first extrusion column 7, the first extrusion column 7 can pass through the first main opening 72 and the first extrusion opening 74 to extrude the medicine bottle 3 installed inside the mounting cavity 21; the main body 1 has a second main opening 73 opposite to the second extrusion column 71, and the medicine bottle placement cylinder 2... A second extrusion opening 75 is provided opposite to the second extrusion post 71. The second extrusion post 71 can pass through the second main body opening 73 and the second extrusion opening 75 to extrude the medicine bottle 3 installed inside the mounting cavity 21. When the upper part of the first extrusion plate 4 and the second extrusion plate 5 is pressed by external force, the first opening plate 41 and the second opening plate 51 can move away from each other to open the upper and lower eyelids. The first extrusion post 7 and the second extrusion post 71 can extrude the medicine bottle 3 located in the mounting cavity 21, causing the medicine to drip downwards.

[0030] When administering eye drops, the patient first places the eye drop bottle 3 inside the eye drop holder 2 and secures it using a limiting structure. After securing the eye drop bottle 3, the patient tilts their head back to an appropriate angle and then places the bottom opening against the contour of the eye socket. Using both hands, the patient simultaneously presses inward the upper parts of the first squeezing plate 4 and the second squeezing plate 5. Under the force, the first squeezing plate 4 and the second squeezing plate 5 drive the bottoms of the first spreading plate 41 and the second spreading plate 51 away from each other, thus opening the upper and lower eyelids. The first squeezing column 7 and the second squeezing column 71 squeeze the eye drop bottle 3 located in the mounting cavity 21, causing the liquid to drip downward onto the surface of the eyeball. Compared to manually instilling eye drops, the eye drop precision instillation aid device in this embodiment can accurately locate the instillation position by placing the end of the bottom opening against the contour of the eye socket, ensuring that the liquid drops accurately onto the surface of the eyeball. In addition, when instilling eye drops, there is no need to touch the eyelid and eyelash area with fingers, avoiding the contact transmission path of bacteria from the hands to the sensitive parts of the eyes, and reducing the risk of eye infection caused by improper operation.

[0031] like Figure 2-3 As shown, the limiting structure includes a limiting seat 6, an elastic element 62, and a limiting nut 63; wherein, the limiting seat 6 is movably installed in the mounting cavity 21, and a limiting through hole 61 is provided in the middle, which is opposite to the drip opening 23; the elastic element 62 is installed between the limiting seat 6 and the base plate 22; the limiting nut 63 has an internal thread and is screwed into the top opening of the mounting cavity 21. Rotating it downwards can squeeze the medicine bottle 3, thereby limiting and fixing the medicine bottle 3 between the limiting nut 63 and the limiting seat 6.

[0032] A tapered nozzle limiting sleeve 64 is formed on the outer circumference of the limiting through hole 61 facing the drip opening 23. The narrow end of the nozzle limiting sleeve 64 is away from the limiting seat 6 and has a lower through hole. The nozzle 31 of the medicine bottle 3 extends into the nozzle limiting sleeve 64 and is vertically opposite to the lower through hole.

[0033] It also includes a first reset elastic element 76 and a second reset elastic element 77; wherein, the first reset elastic element 76 is sleeved on the first extrusion post 7, one end abutting against the first extrusion plate 4, and the other end abutting against the outer wall of the first extrusion opening 74; the second reset elastic element 77 is sleeved on the second extrusion post 71, one end abutting against the second extrusion plate 5, and the other end abutting against the outer wall of the second extrusion opening 75; in the initial state, the first reset elastic element 76 can drive the first extrusion plate 4 to rotate to a position that moves the first extrusion post 7 away from the main body 1; the second reset elastic element 77 can drive the second extrusion plate 5 to rotate to a position that moves the second extrusion post 71 away from the main body 1.

[0034] like Figure 5As shown, the main body 1 has side openings 12 on both sides, opposite to the first extrusion plate 4 and the second extrusion plate 5. Limiting baffles 13 are provided on the inner walls of the side openings 12 near the bottom. These limiting baffles 13 restrict the inward rotation of the first supporting plate 41 and the second supporting plate 51, preventing them from excessively extending into the inner cavity 11.

[0035] like Figure 4-5 As shown, the first extrusion plate 4 and the second extrusion plate 5 are movably mounted on both sides of the main body 1 via a movable structure; the movable structure includes ear pieces 8 and connecting cylinders 82; wherein, there are two ear pieces 8, which are respectively disposed on both sides of the middle of the side opening 12, and each has a movable through hole 81; the connecting cylinder 82 is disposed inside the first extrusion plate 4 and the second extrusion plate 5, is hollow and has openings at both ends; the connecting cylinder 82 is installed between the two ear pieces 8; the connecting shaft 83 passes through the movable through hole 81 on one side, the inner cavity of the connecting cylinder 82 and the movable through hole 81 on the other side, and movably mounts the first extrusion plate 4 and the second extrusion plate 5 on the main body 1.

[0036] The bottom of the first opening plate 41 and the second opening plate 51 are respectively provided with silicone pads 9. The silicone pads 9 can prevent scratches to the user's skin and have a certain friction to better open the eyelids.

[0037] A first observation opening 14 is provided on the side of the main body 1 located between the first extrusion plate 4 and the second extrusion plate 5. When someone is administering eye drops to a user, they can observe the instillation process through the first observation opening 14.

[0038] The medicine bottle holder 2 has second observation openings 15 on both sides, which are opposite to the first observation openings 14 on both sides. The remaining amount of medicine in the medicine bottle 3 can be observed through the second observation openings 15.

[0039] The top of the limiting nut 63 is provided with an operating plate, which allows the limiting nut 63 to be rotated easily.

[0040] In this embodiment, the eye drop precision instillation auxiliary device is used as follows: When the patient is instilling eye drops, first unscrew the limiting nut 63 from the mounting cavity 21, then place the medicine bottle 3 into the mounting cavity 21 from the top opening, so that the dropper 31 extends into the dropper limiting sleeve 64, then screw the limiting nut 63 onto the top of the mounting cavity 21, and rotate it downwards to limit and fix the medicine bottle 3; after fixing the medicine bottle 3, the patient tilts their head back to an appropriate angle, and then places the end of the bottom opening against the contour of the eye socket; using both hands, simultaneously press the first squeezing plate 4 and the second squeezing plate 5 inwards, the first squeezing plate 4 and the second squeezing plate 5, under the action of force, drive the first spreading plate 41 and the second spreading plate 51 away from each other, opening the upper and lower eyelids; the first squeezing column 7 and the second squeezing column 71 squeeze the medicine bottle 3 located in the mounting cavity 21, so that the medicine drips downwards onto the surface of the eyeball.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
