Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and particularly relates to an auxiliary protective device for eye drops. Background Art

[0002] In ophthalmology, eye drops are a common treatment method widely used in the treatment and care of eye diseases. However, for certain patient groups, such as the elderly, children, and those with severe vision loss or limited manual dexterity due to eye diseases, self-administering eye drops can be a challenging task. These patients often struggle to hold their eyelids open steadily when attempting to administer eye drops, resulting in the instillation of the drops into the conjunctival sac. Improper use can even lead to eye discomfort or infection.

[0003] Traditional solutions often rely on the assistance of others, but this approach not only increases the burden on caregivers but can also introduce additional risks due to improper operation. Furthermore, some patients may prefer to complete this procedure independently for reasons of privacy or self-esteem. Consequently, a variety of assistive devices designed to help patients administer eye drops independently have emerged on the market.

[0004] Most of these existing auxiliary tools adopt a mechanical design, such as simple eyelid retractors, which use springs or levers to open the eyelids. However, these tools often have some problems in actual use. First, they have poor stability and are easily dislocated or shifted due to hand shaking or patient head movement during use, resulting in inaccurate instillation of the medicine. Secondly, these tools often lack adjustment functions and cannot adapt to the eye structures and needs of different patients. Furthermore, the design of some tools may be too complicated or bulky, which is not convenient to use and may even bring additional burden or discomfort to patients. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1—3 shows: an auxiliary protective device for eye drops, including an eyelid support frame 1, the eyelid support frame 1 is sleeved on the outside of the elastic band 2, the eyelid support frame 1 is composed of a movable frame 3 and a fixed frame 4, the middle ends of the movable frame 3 and the fixed frame 4 are rotatably connected by a rotating shaft 5, one end of the movable frame 3 and the fixed frame 4 is provided with a handle section 6, the other end of the movable frame 3 and the fixed frame 4 is provided with an arc-shaped expansion section 7, the side surfaces of the two handle sections 6 facing each other are respectively provided with locking teeth 8 and ratchet 9, one end of the ratchet 9 is adapted to engage the tooth groove of the locking teeth 8, and the ratchet 9 is provided with a locking tooth. The side surfaces are elastically supported by an elastic support plate 10, which is mounted on a fixing frame 4. The eyelid support frame 1 is stably fixed to the user's head by the use of an elastic band 2, and the eyelids can be stably supported without the assistance of others. At the same time, the eyelid support frame 1 adopts adjustable and lockable locking teeth 8 and ratchets 9, which can automatically lock in a suitable position after the eyelids are opened, ensuring stability during use. The rotating shaft 5 is a hollow shaft structure, and the elastic band 2 is inserted in the rotating shaft 5. The elastic band 2 can be inserted in the rotating shaft 5 to stably fix the eyelid support frame 1 as a whole in use. Above the user's eyes, the elastic band 2 is composed of a single rope segment 21 and a double rope segment 22. The double rope segment 22 is composed of two elastic ropes of the same size. The two ends of the double rope segment 22 are connected to the two ends of the single rope segment 21. The single rope segment 21 and the double rope segment 22 are respectively located on both sides of the rotating shaft 5. When performing the eye drops operation, the double rope segment 22 can be separately dialed to both sides of the user's eyes, thereby reducing the blocking effect of the elastic band 2 on the eye drops. The elastic support plate 10 is an arc-shaped plate structure. The arc structure of the elastic support plate 10 can stably support the pawl 9, so that the pawl 9 is stably engaged In the tooth groove of the locking tooth 8, the locking tooth 8 is composed of a plurality of right-angled triangle blocks, and the surface where the right-angled side of the locking tooth 8 is located is set toward the rotating shaft 5, and the end of the pawl 9 is clamped in the tooth groove of the locking tooth 8, and is tightly attached to the surface of the locking tooth 8 facing the rotating shaft 5 under the elastic support of the elastic support plate 10, limiting the minimum angle of the movable frame 3 and the fixed frame 4, so that the arc-shaped expansion segment 7 can stably expand the eyelids. The arc-shaped expansion segment 7 is an arc-shaped rod structure, and the edge of the arc-shaped expansion segment 7 is provided with a rounded structure. The arc-shaped expansion segment 7 can fit the shape of the eyeball to expand the eyelids, effectively improving the comfort of the user.

[0031] The working principle of this technical solution is: wear the elastic band 2 on the head, so that the eyelid support frame 1 is located directly above the eye that needs eye drops, and the double rope segment 22 is located on the side of the eye that needs eye drops. Insert the fingers into the handle segment 6 in the movable frame 3 and the fixed frame 4 to rotate the handle segment 6 to both sides to open it, thereby driving the arc-shaped stretching segment 7 against the user's eyelids to stretch the eyelids. As the handle segment 6 rotates, the pawl 9 is adapted to be clamped in the tooth groove of the locking tooth 8 under the elastic support of the elastic support plate 10, thereby realizing the support and limitation of the movable frame 3 and the fixed frame 4, that is, after the user's hand leaves the handle segment 6, the arc-shaped stretching segment 7 can still stably stretch the user's eyelids under the action of the elastic band 2, the locking teeth 8 and the pawl 9, thereby facilitating the eye drops operation.
