[0003] Chinese patent application document 1 (grant announcement number: CN 208756306 U, grant announcement date: 29.04.19) discloses a new ophthalmic eye drop device, which comprises: an eye drop device body 1', a detachable support body 2', and a foot ball 3', the detachable support body 2' comprises a clamping ring 4' and a support 5' rotatably clamped on the clamping ring 4', the foot ball 3' is buckled on the free end of the support 5', the eye drop device body 1' comprises: a telescopic drop nozzle 6' and a trapezoidal bottle body 7', the clamping ring 4' is clamped on the trapezoidal bottle body 7', a buckle cover 8' matched with the telescopic drop nozzle 6' is arranged below the trapezoidal bottle body 7', and a leakage prevention body 9' is arranged inside the buckle cover 8'. The foot ball 3' of the new ophthalmic eye drop device cannot control the blinking of the patient's upper and lower eyelids, causing the eye drops to not enter the eyeball when the eye drops are dropped, resulting in waste; further, the outflow amount of the eye drops cannot be accurately controlled, and the type of the eye drops is fixed, which cannot meet the needs of different eye drop manufacturers.

[0004] Chinese patent application document 2 (grant announcement number: CN 211583793 U, grant announcement date: 2020.09.29) discloses an eye drop support, which comprises: a ring body and a support column, the ring body is provided with a central through hole, and the hole wall of the central through hole is provided with a screw thread, the first ends of the two support columns are respectively connected with the end walls of one end of the ring body, and the two support columns are symmetrically distributed about the central axis of the central through hole of the ring body, the eye lid is supported by the two support columns, and the ring body and the support column are connected together to ensure that the drop nozzle of the eye drop bottle is directly opposite to the eyeball when the user drops the eye drops; the height of the eye drop support cannot be adjusted, for small eyes such as infant patients, the eye drops still cannot avoid falling outside the eye when being dropped into the bottle at a high position; further, the size of the ring body is fixed, and only a single type of eye drop bottle can be used, so the application range is narrow.

[0005] Chinese patent application file 3 (grant announcement number: CN 213465586 U, grant announcement date: 2021.06.18) discloses an eye dropper, which is provided with a hollow triangular platform, a rubber ring matched with an eye drop bottle is threadedly installed on the hollow triangular platform, and three supports are threadedly installed at the lower end of the hollow triangular platform; the lower end of two supports is clamped with a spring leg, and the lower end of the other support is glued with a non-slip foam; the non-slip foam of the eye dropper has limited fixation on the upper and lower eyelids, the drop head cannot be flexed, the size of the hollow triangular platform is fixed, the suitable eye drop type is fixed, and further the medicine output of the eye drops cannot be accurately controlled.

[0006] For example, patent application number 202322059673.1, application date August 2, 2023, discloses an eye dropper, which exposes the eyeball by supporting the eyelid with two push plates, and then accurately drops by pressing the booster, but cannot adjust the drop hole and control the drop speed; patent application number 202320514726.1, application date March 16, 2023, discloses a nursing eye dropper, which moves the expansion rod by pressing the operating handle, then supports the eyelid of the patient with the support block, and supports and stabilizes the height position of the medicine bottle, but cannot adjust the height of the medicine bottle and cannot control the drop flow and drop speed.

The drop hole of the eye dropper is fixed, the drop speed cannot be controlled, and the blinking of the patient's upper and lower eyelids cannot be controlled; patent application number 201610478108.0, application date October 25, 2016, discloses an auxiliary eye dropper and its use method, which can control the blinking of the patient's upper and lower eyelids, but still cannot adjust the drop hole and control the drop speed.

[0008] The application file with the patent application number 200810016044 and the application date of May 14, 2008 discloses an auxiliary eye dropper, which is difficult to use for different patients due to the fixed type, the fixed drop hole, the uncontrollable drop speed, the uncontrollable blinking of the upper and lower eyelids of the patient, the small through hole, the lack of the eye dropper fixing device, and the like. If the user can accurately align the through hole of the eye dropper with the eye, the ordinary eye drop packaging bottle can be accurately dripped, and the funnel-shaped eye dropper is not needed.
