Detailed Implementation

[0028] 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.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] As a common tool in ophthalmic care, eye dropper is designed to help users deliver medication accurately and hygienically to the target area of ​​the eye. In the current technology, these devices have developed into various forms to adapt to different usage scenarios and user needs. From a basic structural perspective, they mainly include three core modules: a medication storage unit, a drop control component, and an auxiliary positioning mechanism. Some high-end models also introduce intelligent components to improve ease of operation. Based on usage methods and structural characteristics, existing products can be divided into three categories: manual operation type, mechanically assisted type, and electronically controlled type. Each type has specific application value in medical scenarios and daily care.

[0031] Traditional manual droppers typically employ a squeeze-type bottle structure made of flexible plastic or glass. Their nozzles are designed with a tapered shape to form controllable droplets. This basic form is commonly found in the original packaging of commercially available eye drops. When used, the pressure difference generated by squeezing the bottle with your fingers causes the liquid to flow out. Although the structure is simple and inexpensive, it requires a high degree of hand stability from the user in actual operation, which can easily lead to problems such as excessive dispensing, liquid contamination, or corneal contact. To address this limitation, existing improvements often involve adding a silicone guide channel or a micro-collecting chamber at the bottle opening. This utilizes the surface tension effect to assist in droplet formation, making the amount of liquid dispensed per squeeze more stable.

[0032] To improve infusion accuracy, some technical solutions add physical positioning devices to the bottle structure. These auxiliary instillers typically include an adjustable forehead rest or nose bridge assembly, establishing a facial reference system through a three-point support structure. An extension arm with angle indicators helps users calibrate the drip trajectory. Some products have a ring-shaped buffer pad around the drip tip, which automatically triggers a limiting mechanism when the device contacts the skin around the eye, ensuring a safe distance between the drip tip and the eyeball. This design is particularly suitable for patients with hand tremors or first-time users. The positioning mechanism is often made of medical-grade ABS plastic, allowing for repeated sterilization and convenient storage through a folding structure. In medical institutions, similar fixation brackets are often used in conjunction with treatment beds to facilitate standardized infusion procedures by medical staff.

[0033] Electrically driven droppers represent an advanced form of technological evolution. Their core lies in replacing manual pressure with micro-motors or piezoelectric ceramic elements. These devices typically have a built-in reservoir and metering pump module, controlling the dosage per dose through preset programs with an error range of microliters. Typical structures include two working modes: contact droppers and non-contact sprays. The former delivers medication point-to-point by gently contacting the lower eyelid with a soft silicone tip, while the latter uses high-frequency vibration to atomize the medication into fine particles for diffused administration. Some high-end models are equipped with infrared distance sensors that automatically release the medication when the distance between the dropper and the eyeball reaches a set threshold, effectively avoiding the risk of accidental contact. These devices often feature USB charging and an IPX4 waterproof casing, making them suitable for daily use by patients with eye diseases who require frequent medication application.

[0034] In terms of hygiene protection, existing technologies focus on preventing cross-infection and drug contamination. Disposable single-dose instillation devices are sterile and individually packaged, with each unit containing a pre-filled 0.5ml drug solution chamber. They are discarded after use. This design eliminates the possibility of contamination from contact with the bottle opening and has important application value in postoperative care and treatment of immunocompromised patients. Another type of detachable drip head design allows for quick replacement through threaded connection and can be reused with an ultraviolet disinfection chamber. Some innovative products have a one-way valve structure inside the storage bottle, which allows the drug solution to flow outwards and prevents backflow, effectively preventing the growth of microorganisms caused by air backflow.

[0035] Technological improvements tailored to the needs of specific populations are also noteworthy. Children's droppers typically integrate fun designs and soothing sound effects; some models release fruit scents during dispensing to distract the user. Products designed for the elderly emphasize enhanced tactile feedback, such as adding non-slip textures to the grip area or using vibration to confirm successful medication delivery. Devices for the visually impaired often feature voice navigation systems that guide head posture adjustments via bone conduction headphones, combined with tactile markers to assist in dropper positioning.

[0036] Current technological development also shows a trend towards intelligent integration. IoT-based droppers can connect to mobile terminals via Bluetooth to record medication time, dosage, and other data in real time and generate electronic medical records. Some experimental products incorporate miniature cameras and use image recognition algorithms to analyze conjunctival congestion and automatically adjust the dosing regimen. In the field of materials science, smart hydrogels with temperature-responsive properties are beginning to be applied to dropper coatings. When in contact with the ocular surface, a phase transition occurs to form a protective film, prolonging the residence time of the medication. Although these innovations are not yet fully widespread, they have already pointed the way for technological upgrades in the industry.

[0037] From a manufacturing process perspective, mainstream products generally use injection molding technology to produce the main structure, while precision components such as spring valves and sensors are processed using microelectromechanical systems (MEMS) technology. Medical-grade silicone, due to its excellent biocompatibility, has become the main material choice for parts that come into contact with the eyes. In the sterilization process, gamma ray irradiation is widely used in the final sterilization process of finished product packaging because of its strong penetrating power and lack of chemical residues.

[0038] While existing technologies have achieved basic infusion functions, they are continuously evolving towards greater precision, user-friendliness, and intelligence. Products using different technological approaches are forming a complementary application pattern in scenarios such as medical institutions, home care, and outdoor emergency care, collectively building a multi-layered ocular drug delivery solution. Basic infusion devices dominate the market due to their affordability and ease of use, while products integrating innovative technologies demonstrate unique value in specific user groups and high-end medical scenarios. This technological diversity not only meets current market demands but also leaves ample room for future research and development improvements.

[0039] Please see Figure 1-4 As shown, this embodiment provides an eye dropper, including: a dropper housing 1 and two auxiliary components. A screw cylinder 5 is rotatably fitted on the upper part of the dropper housing 1, and the lower end of the screw cylinder 5 is located inside the dropper housing 1.

[0040] The screw barrel 5 has two drive plates 7 that rotate and engage with the side. The inner wall of the dripper housing 1 is equipped with two guide rods 13 and two springs 14. The springs 14 are located around the guide rods 13. The auxiliary component is equipped with a second fixing plate 10. A fixing post 9 is installed on the upper side of the second fixing plate 10. The drive plates 7 rotate and engage with the upper end face of the fixing post 9. The guide rods 13 pass through the fixing post 9 laterally.

[0041] One application of this embodiment is as follows: In use, first unscrew the cap of the eye dropper 18, then screw the neck of the eye dropper 18 into the screw cylinder 5, thus connecting the eye dropper 18 to the dropper applicator. Next, cover the eye where the eye drops need to be instilled with the dropper housing 1, ensuring that the two auxiliary components are in contact with the upper and lower eyelids respectively. At this point, the eye dropper 18 can be rotated to cause the screw cylinder 5 to rotate. The rotation of the screw cylinder 5, through the drive plate 7, pushes the fixing post 9 to slide along the guide rod 13, compressing the spring 14. The displacement of the fixing post 9 causes the fixing plate 10 and the auxiliary components to move synchronously, thereby separating the two auxiliary components and opening the upper and lower eyelids. The user can then squeeze the eye dropper 18 to instill the drops into the eye. Afterward, the dropper applicator can be removed and the eye dropper 18 released. The spring 14 then rebounds, pushing the fixing post 9 to slide back to its original position. Finally, the eye dropper 18 can be detached from the dropper applicator. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.

[0042] The screw cylinder 5 facilitates the connection and fixation of the eye drops 18, reducing the probability of the eye drops 18 falling and scratching the user. It also facilitates the rotation of the screw cylinder 5 by the eye drops 18, and pushes the fixed post 9, fixed plate 10 and auxiliary components to slide through the drive plate 7. The auxiliary components allow the user to simultaneously open the eyelid and drip the eye drops with one hand. The fixed post 9 facilitates the sliding of the auxiliary components by pushing and pulling the drive plate 7. The spring 14 facilitates the reset of the auxiliary components, reducing the complexity of manual adjustment and improving the continuity and safety of operation. The guide rod 13 helps to increase the stability of the spring 14 when it rebounds, and also helps to guide the sliding direction of the fixed post 9.

[0043] like Figure 1 , 2As shown, in this embodiment, an annular rubber pad 2 is installed on the lower side of the dropper housing 1, and a rotating hole is provided on the upper side of the dropper housing 1. The rotating hole is connected to the inner cavity of the dropper housing 1. A bearing 4 is installed around the rotating hole. The bearing 4 is installed around the screw barrel 5. The annular rubber pad 2 helps to increase the friction between the dropper housing 1 and the skin, reducing the probability of the dropper housing 1 detaching from the eye during use. The bearing 4 helps to reduce the friction between the screw barrel 5 and the dropper housing 1 when rotating. The rotating hole facilitates the insertion of the eye drops 18 into the dropper housing 1.

[0044] like Figure 2 , 3 As shown, in this embodiment, the screw cylinder 5 is equipped with two fixing plates 6 on its side. The upper side of the fixing plate 6 is equipped with a protruding post 1, and the upper side of the fixing post 9 is equipped with a protruding post 2. The two ends of the drive plate 7 are respectively rotatably engaged with the protruding post 1 and the protruding post 2 on their periphery. The engagement of the protruding post 1 and the protruding post 2 helps to increase the stability of the drive plate 7 when it rotates.

[0045] like Figure 2 , 3 As shown, in this embodiment, the upper end face of both protrusion one and protrusion two is equipped with a limiting plate 8. The limiting plate 8 is located on the upper side of the drive plate 7. The limiting plate 8 helps to reduce the probability of the limiting plate 8 falling off from protrusion one or protrusion two.

[0046] like Figure 2-4 As shown, in this embodiment, the guide rod 13 is equipped with a limiting plate 2 11 around its periphery and a push plate 12 is sleeved on it. The spring 14 is installed on one side of the push plate 12. The screw cylinder 5 is located between the two limiting plates 2 11. The fixing post 9 is located between the limiting plate 2 11 and the push plate 12. The limiting plate 2 11 is used to limit the sliding distance of the fixing post 9. The push plate 12 is used to facilitate the spring 14 to push the fixing post 9 to slide. At the same time, it is also convenient to increase the contact area between the spring 14 and the fixing post 9.

[0047] like Figure 2-4 As shown, the auxiliary component of this embodiment includes an arc-shaped plate 15, a fixing plate 2 10 is installed on the side of the arc-shaped plate 15, and an arc-shaped rubber strip 16 is snapped onto the lower side of the arc-shaped plate 15. The arc-shaped rubber strip 16 increases the friction between the arc-shaped plate 15 and the eyelid, while reducing the probability of the arc-shaped plate 15 displacement causing scratches to the eyelid.

[0048] like Figure 2-4 As shown, the lower side of the arc plate 15 in this embodiment is equipped with an arc-shaped retaining strip 3. The vertical cross-section of the arc-shaped retaining strip 3 is an inverted T-shaped structure. The upper side of the arc-shaped rubber strip 16 is provided with a T-shaped groove corresponding to the arc-shaped retaining strip 3. The T-shaped groove passes through the arc-shaped rubber strip 16 laterally. The arc-shaped rubber strip 16 is engaged with the arc-shaped retaining strip 3 through the T-shaped groove. The arc-shaped retaining strip 3 and the T-shaped groove cooperate to facilitate the user to quickly disassemble and install the arc-shaped rubber strip 16.

[0049] like Figure 2-4 As shown, the T-shaped groove in this embodiment has two hemispherical rubber protrusions on its lower side. The two hemispherical rubber protrusions are distributed at both ends of the arc-shaped rubber strip 16. The arc-shaped retaining strip 3 has a hemispherical groove on its lower side that corresponds to the hemispherical rubber protrusions. The hemispherical rubber protrusions are engaged in the hemispherical grooves. The hemispherical rubber protrusions help to increase the resistance between the arc-shaped rubber strip 16 and the arc-shaped retaining strip 3, thereby reducing the probability of the arc-shaped rubber strip 16 falling off the arc-shaped retaining strip 3.
