When in use, the sliders on both sides of the sliding positioning frame slide along the slide groove in the fixed frame, and the positioning frame drives the slider to slide to the specified position in the slide groove. Press the positioning frame down to enter the next slide groove, and move to the specified position according to the position of the patient's eyes. Then, turn the squeezing column to squeeze and limit the fixed frame. When the other eye needs to drop medicine, turn the squeezing column in the opposite direction, then move the positioning frame to the specified position, and turn the squeezing column to squeeze and limit the fixed frame.

[0015] 4. The device comprises a first set of rods, a second set of rods, a U-shaped plate, a first fixed column, a limit block, a limit spring, a pull rope, a second fixed column, and a toothed plate, which increases the function of fixing the eye drop bottle. The pull rope is pulled, and the pull rope drives the limit block to move to the left. When the limit block moves to the left, it squeezes the limit spring to move to the left. At this time, the limit block releases the cooperation with the toothed plate, and the U-shaped plate is moved upward. The U-shaped plate drives the first set of rods and the first fixed column to rise to a specified height, and then the pull rope is released. The limit spring drives the limit block to reset, and then the eye drop bottle is put into the groove of the moving plate, and the U-shaped plate is pressed downward. The U-shaped plate drives the first set of rods and the first fixed column to move downward. During the downward movement of the limit block inside the first fixed column, the toothed plate squeezes the limit block and shrinks and moves downward. When it moves to the specified position, the limit spring drives the limit block to reset and get stuck in the specified position of the toothed plate to fix the eye drop bottle.

[0016] 5. The device comprises a first fixed plate, a first T-shaped rod, a first return spring, a second fixed plate, a second T-shaped rod, and a second return spring, which have the function of absorbing tears. The device moves by pulling the first T-shaped rod and the second T-shaped rod at both ends.

Then, the absorbent cloth is placed on the first eye-supporting plate and the second eye-supporting plate, and the first T-shaped rod and the second T-shaped rod are respectively loosened. The first return spring and the second return spring respectively drive the first T-shaped rod and the second T-shaped rod to reset. At this time, the absorbent cloth on the first eye-supporting plate and the second eye-supporting plate is fixed. After the patient has dripped the eye drops, the tears flowing out are absorbed by the absorbent cloth to prevent the tears from flowing into the patient's mouth after the patient has dripped the eye drops.

[0017] 6. This device has elastic Velcro, which adds the function of fixing it on the head. When in use, the device is fixed on the eyes to facilitate patients to independently complete eye drops. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] When in use, put the dropper port into the groove in the middle of the movable plate 4, and then fix the eye drop bottle by the fixing mechanism 21. After the eye drop bottle is fixed, the fixing frame 2004 is fixed to the patient's head by the limiting mechanism 20, and then the positioning frame 1 is slid on the limiting mechanism 20 to adjust the positioning frame 1 to the patient's eye position. The patient's head tilts back slightly, and the thumb and index finger are used to press the first pressing plate 3 and the second pressing plate 13 to gather together in the middle. The first pressing plate 3 and the second pressing plate 13 respectively drive the first L-toothed plate 2 and the second L-toothed plate 12 when they gather together in the middle. At this time, the first L-toothed plate 2 drives the first gear 8, and the first gear 8 drives the first limiting ball 9 at the upper end when it rotates. The first limiting ball 9 moves from the first limiting groove 7 when it rotates. When the first gear 8 is in a state of continuous rotation, the first limiting ball 9 at the upper end is driven to reciprocately enter and fall off the first limiting groove 7.

When the second squeezing spring 15 stops, the second limiting groove 16 in the second slide post 14 coincides with the second limiting ball 18. At this time, the second limiting groove 16 at the lower end of the second slide post is aligned with the second limiting ball 18 and the second gear 17. The second eye supporting plate 19 is limited in position, and the second eye supporting plate 19 drives the second eye supporting plate 19 to move outward when rotating, and the second eye supporting plate 19 contacts with the upper eyelid, and the second eye supporting plate 19 opens the upper eyelid. After the first eye supporting plate 10 and the second eye supporting plate 19 open the upper eyelid and the lower eyelid at the same time, the lifting mechanism 11 is rotated, and the lifting mechanism 11 drives the first L-toothed plate 2 and the second L-toothed plate 12 to rise to the specified position, and then the first L-toothed plate 2 and the second L-toothed plate 12 are disengaged from the meshing with the first gear 8 and the second gear 17.

After the eye drop bottle is fixed, the fixing frame 20 is fixed to the patient's head by the limiting mechanism 20, and then the positioning frame 1 is slid on the limiting mechanism 20 to adjust the positioning frame 1 to the patient's head. The patient's eye position, the patient's head slightly tilts back, and the thumb and index finger are used to press the first pressing plate 3 and the second pressing plate 13 to gather together. When the first pressing plate 3 and the second pressing plate 13 gather together, they drive the first L-toothed plate 2 and the second L-toothed plate 12 respectively. At this time, the first L-toothed plate 2 drives the first gear 8, and the first gear 8 drives the first limiting ball 9 at the upper end when rotating. The first limiting ball 9 disengages from the first limiting groove 7 when rotating, thereby driving the first sliding column 5 to rise. The first sliding column 5 squeezes the first squeezing spring 6 when rising. When the first limiting ball 9 enters the first limiting groove 7, the first squeezing spring 6 drives the first sliding column 5 to reset. When the first gear 8 is in a state of continuous rotation, it drives the first limiting ball 9 at the upper end to reciprocate. When the first limit plate 10 is in the state of being moved upward, the first limit ball 18 is pressed against the second limit plate 11 and the second limit ball 11 is pressed downward, and the second limit ball 18 is pressed downward, thereby the second limit plate 10 is in the state of being moved upward. When the second gear 17 is in a state of continuous rotation, the second extrusion spring 15 drives the second sliding column 14 to reset. When the second gear 17 is in a state of continuous rotation, the second limiting ball 18 at the upper end is driven to reciprocately enter and fall off the second limiting groove 16. When the second extrusion spring 15 drives the second limiting groove 16 and the second limiting ball 18 in the second sliding column 14 to overlap. At this time, the second limiting groove 16 at the lower end of the second sliding column limits the second limiting ball 18 and the second gear 17. When the second gear 17 rotates, it drives the second eye support plate 19 to move outward. The second eye support plate 19 contacts the upper eyelid, and the second eye support plate 19 opens the upper eyelid. After the first eye support plate 10 and the second eye support plate 19 open the upper eyelid and the lower eyelid at the same time, the lifting mechanism 11 is rotated.The lifting mechanism 11 will drive the first L-toothed plate 2 and the second L-toothed plate 12 to rise to the specified position, and then the first L-toothed plate 2 and the second L-toothed plate 12 will disengage from the meshing with the first gear 8 and the second gear 17. At this time, the first pressing plate 3 and the second pressing plate 13 will not drive the first gear 8 and the second gear 17 to rotate when squeezing the eye drops bottle. The position is adjusted by sliding the moving plate 4 forward. After the patient has finished dropping the eyes, the lifting mechanism 11 is turned. The lifting mechanism 11 drives the first L-toothed plate 2 and the second L-toothed plate 12 to mesh with the first gear 8 and the second gear 17 respectively. When the first gear 8 and the second gear 17 move outward, they drive the first eye support plate 10 and the second eye support plate 19 to start to reset. After resetting, the limiting grooves on the first slide post 5 and the second slide post 14 The first limiting ball 9 and the second limiting ball 18 on the first gear 8 and the second gear 17 are limited, and the first T-shaped rod 27 and the second T-shaped rod 30 at both ends are pulled to move. The first T-shaped rod 27 and the second T-shaped rod 30 squeeze the first return spring 28 and the second spring respectively to shrink while moving, and then put the absorbent cloth on the first eye support plate 10 and the second eye support plate 19, loosen the first T-shaped rod 27 and the second T-shaped rod 30 respectively, and the first return spring 28 and the second return spring 31 respectively drive the first T-shaped rod 27 and the second T-shaped rod 30 to reset. At this time, the absorbent cloth on the first eye support plate 10 and the second eye support plate 19 is fixed, and the patient absorbs the tears after dripping the eye drops through the absorbent cloth to prevent the tears from flowing into the patient's mouth after dripping the eye drops.

[0047] The present invention has a novel structure, ingenious conception, and simple and convenient operation. Through this design, the purpose of assisting patients to independently complete eye drops is effectively achieved. A new function of making adjustments when pressing eye drops bottles at different heights is added, a function of adjusting the eye distance is added, a function of fixing the eye drops bottle is added, a function of absorbing tears is added, and a function of fixing on the head is added.
