Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary equipment technology, specifically referring to an eye drop instillation aid. Background Technology

[0002] Ophthalmology is an important branch of medicine, focusing on the prevention, diagnosis, and treatment of diseases of the eye and its related structures and visual system. It encompasses the prevention, diagnosis, and treatment of everything from common vision problems to complex eye diseases. Ophthalmologists treat a wide range of diseases, including refractive errors such as myopia, hyperopia, and astigmatism, as well as blinding eye diseases such as cataracts, glaucoma, and macular degeneration. Furthermore, ocular surface diseases such as conjunctivitis and dry eye syndrome, and ocular complications caused by systemic diseases such as diabetic retinopathy, also fall within their scope of expertise.

[0003] In the daily care and treatment of ophthalmic diseases, eye drops are the most basic and commonly used method of administration. The ease of operation and accuracy of administration directly affect the treatment effect and eye comfort. Currently, when patients administer eye drops themselves, they generally rely on holding the eye drop bottle, which presents several problems that urgently need to be addressed: First, patients are prone to hand tremors due to tension and lack of hand muscle coordination, causing the drop to fall off-center, wasting medication and failing to ensure accurate placement within the conjunctival sac, thus reducing the effectiveness of administration. Second, some patients experience temporary vision loss after treatment, or elderly patients and children have pre-existing poor vision, making it difficult to accurately judge the relative position of the bottle opening to the eyeball. This may result in the bottle opening being too close to or even directly touching the eye, causing secondary eye irritation, corneal abrasion, etc. Furthermore, if the head tilt angle is not properly controlled during instillation, or the bottle tilt angle is unreasonable, the medication may easily drip onto non-target areas such as the face and eyelids. This not only fails to achieve the desired effect but may also irritate the skin due to medication residue. If the medication is accidentally dripped onto the cornea, it can cause corneal irritation and worsen eye discomfort. In addition, the traditional handheld method lacks fixed support, and prolonged operation can easily lead to arm soreness, further affecting the stability of the instillation. These problems are particularly prominent for patients who need to instill eye drops regularly and for a long time. There is an urgent need for a device that can assist in accurate and safe instillation to solve the drawbacks of the existing instillation method. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an eye drop instillation aid. Addressing the problems of hand tremors and inaccurate drop placement during handheld instillation, it employs negative pressure fixation and pupil calibration. By incorporating a negative pressure adsorption base and a pupil calibrator, it achieves stable instillation and precise drop placement onto the conjunctival sac, solving the problems of wasted medication and low drug efficacy. To prevent the bottle opening from easily touching the eye and causing secondary injury during instillation, this invention creatively proposes a structure with a magnetic suction nozzle and a bottle squeezing arm. By magnetically fixing the eye drop bottle and mechanically controlling the bottle squeezing and bottle opening positioning, it maintains a safe distance between the bottle opening and the eyeball, avoiding direct contact.

[0005] To address the issues of eyelids obstructing the conjunctival sac and medication easily dripping onto the eyelids during infusion, a mechanical support linkage system is employed. This system includes upper and lower eyelid support arms and silicone anti-slip strips, which automatically open the eyelids, expose the conjunctival sac, and ensure precise medication delivery.

[0006] The technical solution adopted by the present invention is as follows: an eye drop instillation aid, comprising a negative pressure adsorption base, a pupil calibrator and a liquid squeezer, wherein the negative pressure adsorption base is adsorbed onto the patient's face, the pupil calibrator is slidably connected to the negative pressure adsorption base, and the liquid squeezer is disposed on the negative pressure adsorption base.

[0007] Furthermore, the negative pressure adsorption base includes an adsorption arm, an upper suction cup, a lower suction cup, a squeezing airbag, and a connecting air tube. The upper suction cup is located on the inner side of the front end of the adsorption arm, the lower suction cup is located on the inner side of the rear end of the adsorption arm, and the squeezing airbag is located on the outer side of the rear end of the adsorption arm. Both the upper and lower suction cups are connected to the squeezing airbag via the connecting air tube. The adsorption arm provides an adjustable mounting bracket and uses locking teeth for positioning. The upper and lower suction cups achieve a stable connection with the face through negative pressure adsorption. The squeezing airbag, in conjunction with the connecting air tube, provides a stable negative pressure source for the suction cups, ensuring that the device does not fall off.

[0008] Furthermore, the inner side of the adsorption arm is provided with protruding locking teeth, which provide a mechanical positioning buckle for the sliding adjustment of the pupil calibrator, realizing the device's precise adaptation and locking fixation for patients of different heights and facial contours.

[0009] Furthermore, the pupil calibrator includes a sliding component and a calibration component. The sliding component is slidably connected to the adsorption arm, and the calibration component is disposed on the sliding component. The sliding component is responsible for realizing the overall lifting and lowering and position locking of the pupil calibrator; the calibration component is the core of visual alignment, ensuring that the drop position is collinear with the pupil through optical guidance.

[0010] Furthermore, the sliding assembly includes a sliding bracket, a pressing bracket, and a pressing spring. The sliding bracket is slidably connected to the adsorption arm, and the pressing bracket is slidably connected to the sliding bracket. One end of the pressing spring is fixedly connected to the sliding bracket, and the other end of the pressing spring is fixedly connected to the pressing bracket. The pressing bracket engages with the locking teeth. The sliding bracket serves as the mounting carrier for the calibration assembly and allows it to slide along the arm. The pressing bracket, in conjunction with the locking teeth, enables one-button unlocking and positioning. The pressing spring provides the elastic preload required for engagement, ensuring that the adjusted position remains fixed and does not loosen.

[0011] Furthermore, the calibration component includes an inner slider, an outer slider, a pusher rod, and a calibration lever. Both the inner and outer sliders are slidably connected to a sliding base. The lower end of the pusher rod is fixedly connected to the inner slider, and the outer slider is slidably connected to the pusher rod. The calibration lever is fixedly connected to the inner slider. Both the inner and outer sliders have semi-circular holes on their inner sides. The inner and outer sliders cooperate to form a collinear optical channel, providing the user with a three-point aligned visual aiming reference. The calibration lever facilitates the opening and closing of the sliders. The circular hole formed by the semi-circular holes serves as a visual guide for the dripping path, ensuring the accuracy of the medication drip.

[0012] Furthermore, the liquid medicine squeezer includes a squeeze bracket, a magnetic suction nozzle, and a manual squeeze arm. The squeeze bracket is mounted on a sliding base and has symmetrical rotating shafts. The ends of the symmetrical rotating shafts are equipped with rotating gears, which mesh with each other. The manual squeeze arm is fixedly connected to the rotating shafts. The magnetic suction nozzle is slidably mounted on the squeeze bracket. The squeeze bracket is the mounting frame of the liquid medicine squeezer, supporting all functional components. The rotating shafts and rotating gears form the transmission core, realizing the power transmission and synchronous movement of the manual squeeze arm. The magnetic suction nozzle enables rapid adsorption and fixation of the medicine bottle and prevents contact at the bottle opening.

[0013] Furthermore, the magnetic suction nozzle consists of two sets of symmetrical magnetic suction bases, which are made of magnets and are slidably connected to the compression bracket. The magnetic attraction force is used to achieve quick and contactless installation and fixation of the medicine bottle. The symmetrical structure ensures that the center of the medicine bottle is aligned during installation, and the sliding design makes it easy to adapt to medicine bottles of different sizes.

[0014] Furthermore, a medicine bottle squeezing arm is fixedly connected to the symmetrical rotating shaft, and an upper eyelid support arm is rotatably connected to the symmetrical rotating shaft. A damping spring is sleeved on the rotating shaft, with one end of the damping spring fixedly connected to the rotating shaft and the other end fixedly connected to the upper eyelid support arm. A lower eyelid support arm is rotatably connected to the squeezing bracket, and a silicone anti-slip strip is slidably connected to the squeezing bracket. The silicone anti-slip strip is slidably connected to the lower eyelid support arm, and the lower end of the upper eyelid support arm is slidably connected to the upper end of the lower eyelid support arm. The medicine bottle squeezing arm achieves controllable squeezing of the medicine bottle under the drive of the rotating shaft. The upper eyelid support arm automatically opens the upper eyelid under the drive of the damping spring, and in conjunction with the lower eyelid support arm and the silicone anti-slip strip, opens the lower eyelid. This linkage structure realizes an integrated design of eyelid opening and medicine bottle positioning, which is simple and efficient to operate.

[0015] The beneficial effects of the eye drop instillation aid provided in this solution are as follows: (1) In view of the problems of hand tremors and displacement of the drip position when hand-held dripping, a negative pressure adsorption fixed base is adopted. The negative pressure adsorption base is set up to achieve the technical effect of stable contact between the device and the patient's face and avoid the device shaking during dripping, thus solving the technical problems of drug waste and low drug delivery effectiveness. (2) In view of the problem that patients have difficulty accurately judging the relative position of the medicine bottle and the eyeball, a sliding adjustment and pupil calibration method is adopted to set up a pupil calibrator, which realizes the technical effect of accurately aligning the drip position with the pupil and ensuring that the medicine is dripped into the conjunctival sac, thus solving the technical problem of low drip accuracy; (3) In view of the problem that the mouth of the medicine bottle is easy to touch the eyes and cause secondary damage, magnetic fixation and mechanical positioning are adopted. A magnetic mouthpiece and a medicine bottle squeezing arm are set up to achieve the technical effect of stable fixation of the medicine bottle and maintaining a safe distance between the mouth of the bottle and the eyeball, thus solving the technical problem that the eyes are easily scratched and irritated. (4) In view of the problem that the eyelids cover the conjunctival sac during infusion, a linkage support method is adopted, and an upper eyelid support arm, a lower eyelid support arm and a silicone anti-slip strip are set up to achieve the technical effect of automatically opening the eyelids and exposing the conjunctival sac, thus solving the technical problem that the medicine is easy to drip onto the eyelids and cannot exert its effect. (5) Based on the differences in facial contours and eye positions among different patients, a sliding adjustment method is adopted, and an adsorption arm with locking teeth and a sliding base are set up. This enables the pupil calibrator and the drug squeezer to be adjusted up and down to adapt to different patients and solves the technical problem of poor device versatility.

[0024] The liquid extruder 3 includes an extrusion bracket 301, a magnetic suction nozzle 305, and a manual extrusion arm 306. The extrusion bracket 301 is mounted on a sliding base 203 and has symmetrical rotating shafts 302.

[0025] In practical use, the first step is to install the device. With the patient looking straight ahead, attach the negative pressure suction base 1 to the patient's face. First, attach the upper suction cup 102 to the forehead above the eye where the drops are placed, and then attach the lower suction cup 103 to the cheek below the eye where the drops are placed. At the same time, keep the suction arm 101 in front of the patient's field of vision. Press and squeeze the airbag 104. After squeezing the airbag 104, it will recover under its own elasticity. Squeezing the airbag 104 will extract the air from the upper suction cup 102 and the lower suction cup 103 through the connecting air tube 105. At this time, the upper suction cup 102 and the lower suction cup 103 are respectively attached to the patient's forehead and cheek. The second step is to calibrate the patient's pupils. Press the squeeze holder 204, which separates from the teeth 106 of the suction arm 101. Simultaneously, the squeeze holder 204 compresses the squeeze spring 205. At this point, the squeeze holder 204 and the calibration component 202 can slide freely on the suction arm 101. Press the calibration lever 209 to bring the two sets of inner sliders 206 closer together. During the sliding of the inner sliders 206, the outer slider 207 slides along the sliding rail of the sliding holder 203. Driven by the trace, it slides synchronously outward (away from the eyeball). Then, the two sets of inner sliders 206 and outer sliders 207 close respectively. The semi-circular holes on the inner sides of the inner sliders 206 and outer sliders 207 form a circular hole. Through the collinearity of the three points, the ambient light enters the eyeball through the circular hole formed by the outer sliders 207 and the circular hole formed by the inner sliders 206 in sequence, ensuring that the drop position is collinear with the eyeball. Then, the inner sliders 206 and outer sliders 207 are separated by the calibration lever 209. The third step is to begin the instillation. Insert the mouthpiece of the eye drop bottle into the magnetic chuck 305, and gently press the manual squeeze arm 306. The manual squeeze arm 306 drives the rotating shaft 302 to rotate, which in turn drives the bottle squeeze arm 304 to rotate, ensuring that the bottle squeeze arm 304 is in close contact with the outer wall of the drop bottle. Simultaneously, the rotation of the rotating shaft 302 compresses the damping spring 310, causing the upper eyelid support arm 307 to rotate. The upper eyelid support arm 307 pushes the upper end of the lower eyelid support arm 308 inward, while the lower end of the lower eyelid support arm 308 rotates outward, causing the silicone anti-slip strip 309 to slide downward, ensuring that the silicone anti-slip strip 309 is in close contact with the patient's eyelid. Then, the patient tilts their head back and presses the manual squeeze arm 306, using the bottle squeeze arm 304 to squeeze the drop bottle and allow the medication to drip into the patient's eyeball, completing the instillation. The entire instillation operation can be completed independently by a single person without assistance, and the positioning, eyelid opening, and liquid expulsion can be completed in one integrated action without the need for assistance from others.
