[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-4 An eye drop dispenser in this embodiment includes a housing 1, and a clamping device 2 is provided on the bottom of the outer surface of the housing 1.

[0024] The clamping device 2 includes a hinge seat 201, which is fixedly installed on both sides of the bottom of the chamber 1. A torsion spring 202 is provided in the middle of the hinge seat 2, one end of which is fixed to the inner wall of the hinge seat 201, and the other end is fixedly connected to the clamping arm 203. The clamping arm 203 has an L-shaped structure, one end of which is hinged to the hinge seat 201, and the other end extends through the chamber 1 into its interior.

[0025] The bottom of the chamber 1 is provided with a rubber goggle 3 and the top is provided with a back cover 4; a knob 5 is provided above the back cover 4, the knob 5 is threadedly connected to the back cover 4, and the end of the knob 5 facing the inside of the chamber 1 is fixedly connected to a pressure plate 6.

[0026] The edge of the rubber eye mask 3 is connected to the outer peripheral surface of the front end of the chamber 1 by threads, and the inner peripheral surface of the back cover 4 is also connected to the outer peripheral surface of the rear end of the chamber 1 by threads, and the threaded connection parts are all polished. This connection method not only facilitates the quick disassembly and assembly of the rubber eye mask 3 and the back cover 4, making it convenient to replace different sizes of rubber eye masks 3 according to usage needs, and to easily place or remove the eye drop bottle into the chamber 1, but also ensures the sealing of the connection, preventing impurities from entering the chamber 1 and contaminating the eye drop bottle during use.

[0027] The end of the clamping arm 203 extending into the compartment 1 is provided with a barb claw 7. The barb claw 7 is bent and its contact part is smoothed. The barb claw 7 can be engaged with the inner wall of the compartment 1 to stably fix the clamping arm 203 inside the compartment 1, prevent the clamping arm 203 from shaking when not in operation, ensure the stability of the structural connection, and provide reliable support for the pressing operation.

[0028] The bottom of the inner chamber 1, near the front, has a stepped groove 8 that fits the top of the eye drop bottle. The height and width of each step in the stepped groove 8 are designed according to the common top size of eye drop bottles. The stepped groove 8 can stabilize and limit the eye drop bottle from the bottom, effectively preventing the eye drop bottle from deviating from the drip position due to shaking or tilting inside the chamber 1. Combined with the fixing function of the back cover 4, it further enhances the stability of the eye drop bottle during use, ensuring that each drop is accurately aimed at the eye.

[0029] The outer surface of the knob 5 has several raised ridges 9 evenly distributed around its circumference. The height of the raised ridges 9 is 3mm, the spacing between adjacent raised ridges 9 is equal, and the surface of the raised ridges 9 is treated with an anti-slip texture. The raised ridges 9 can greatly increase the friction between the hand and the knob 5, so that the knob 5 can be easily rotated even when the hands are wet. This makes it easy to quickly fix or loosen different sizes of eye drop bottles, saving time and effort during operation, and is especially suitable for people with less hand strength.

[0030] The outer surfaces of both sides of the compartment 1 have grooves corresponding to the positions of the clamping arms 203 in their natural state. The length of the grooves is slightly longer than the width of the clamping arms 203, and the depth of the grooves matches the thickness of the clamping arms 203. The grooves can completely accommodate the clamping arms 203, so that the clamping arms 203 remain flat with the outer surface of the compartment 1 in their natural state. This not only prevents the protruding parts from snagging on other items when carrying or storing the compartment, but also makes the user feel more comfortable when holding the compartment 1, improving the convenience of operation.

[0031] An anti-slip protrusion 10 is provided in the middle of the outer surface of the clamping arm 203. The anti-slip protrusion 10 is elliptical in shape, with a height of 2mm and a fine textured surface. The anti-slip protrusion 10 can accurately fit the finger pressing area, significantly increasing the friction between the hand and the clamping arm 203. Even when the finger presses hard, it can effectively prevent slippage, making the pressing operation more stable and accurate, and reducing the waste of medicine and the error of dripping medicine caused by slippage.

[0032] In summary, when using this device, first unscrew the back cap and place the eye drop bottle into the chamber. The stepped groove at the bottom of the chamber will initially limit the top of the bottle. After tightening the back cap, rotate the knob with raised edges on the outer surface to move the internal pressure plate, which, in conjunction with the stepped groove, fixes the eye drop bottle from top to bottom, ensuring it does not wobble within the chamber. When administering medication, place the rubber eye mask against the eye socket, using its curved contour to fix the device's position. Press the clamping arms with anti-slip protrusions on both sides; their internal barbed claws cooperate with the chamber to apply stable force, squeezing the eye drop bottle to dispense the medication. After releasing the clamping arms, the device automatically resets under the action of a torsion spring, completing a precise medication administration process.

[0033] This solution boasts significant advantages, with a structural design that balances practicality and comfort: the threaded connection between the rubber eyecup and the back cover not only facilitates component replacement as needed but also adapts to different sizes of eye drop bottles, enhancing the device's versatility; the combination of barbed claws and stepped grooves strengthens the fixing effect from both inside and outside, preventing bottle displacement during administration, and, combined with the positioning function of the rubber eyecup, significantly improves the accuracy of medication application; the anti-slip protrusions on the clamping arm, the raised ridges of the knob, and the groove design of the chamber enhance friction and grip during operation, reducing hand slippage and making it easy for children, the elderly, and other groups to use, effectively reducing medication waste. The overall structure is compact and reasonable, combining stability and convenience.
