Description

Technical Field

[0001] This utility model relates to the field of experimental medicine, specifically to a detachable, non-invasive eye patch for inducing myopia in small animals. Background Technology

[0002] The induction of myopia models in small and medium-sized animals such as mice, guinea pigs, and tree shrews falls into two main categories: form deprivation myopia and optical defocus myopia. The most commonly used method for form deprivation myopia is the eyelid suturing method, followed by the occlusion method.

[0003] Eyelid suturing is invasive to animals, causing pain and stress. Local wounds are prone to infection. Sutures may come loose during the daily activities of small animals, leading to modeling failure. Long-term abrasion of the cornea can cause corneal damage. The procedure is cumbersome. Eyelid suturing is not conducive to the measurement of biological parameters during the experiment. After suturing, it is impossible to operate or observe the modeled eye, such as intraocular injection or antibiotic eye drops.

[0004] Covering methods, such as using semi-transparent balloons, have the disadvantage of being non-breathable. When used on small animals like guinea pigs, liquid residue can remain inside the headgear, leading to hair loss around the eyelids and skin ulceration.

[0005] Furthermore, the relatively enclosed environment of small animal eyes has poor air permeability, which can easily lead to corneal hypoxia, resulting in inflammation and ulceration. Existing inventions struggle to balance adequate air permeability with the need for painless, on-call administration of anti-inflammatory eye drops. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a detachable non-invasive eye patch for myopia induction in small animals, which mainly solves the problem that the current eye patches for myopia induction in small animals cannot meet the requirements of painless removal and application of anti-inflammatory eye drops every day.

[0007] The technical solution of this utility model is as follows: A detachable, non-invasive eye patch for inducing myopia in small animals, comprising: The bottom of the adhesive pad has an adhesive part for bonding with the face of a small animal; The top cover includes a foldable and connectable base plate and a sub-plate. The base plate is directly or indirectly connected to the bottom adhesive. The sub-plate is provided with a light shield. When the sub-plate is folded, the animal's eyeballs are exposed. When the sub-plate is unfolded, the animal's eyeballs are located inside the light shield.

[0008] The bottom adhesive includes a first ring and a second ring, which are concentric and form a connected annular groove and a gap groove. The gap groove is used for air to flow into the annular groove.

[0009] It also includes an intermediate ring, the bottom end face of which is detachably connected to the bottom patch.

[0010] The bottom end face of the intermediate ring is detachably connected to the bottom adhesive via a Velcro structure.

[0011] The intermediate ring includes a first half-ring and a second half-ring, wherein the first half-ring is detachably connected to the first ring body and the second half-ring is detachably connected to the second ring body.

[0012] Part of the first half-ring is fixedly connected to the substrate.

[0013] The first half-ring is provided with a boss, which is fixedly connected to the substrate.

[0014] The second half-ring is fixedly connected to the sub-piece.

[0015] A crease groove is provided between the substrate and the sub-film.

[0016] The beneficial effects of this utility model are: This utility model provides a detachable non-invasive eye patch for inducing myopia in small animals, which does not require suturing and can be opened at any time to administer eye drops, making it convenient to operate.

[0022] The present invention will be further described below with reference to the accompanying drawings. A detachable non-invasive eye patch for inducing myopia in small animals includes a base patch 1, the bottom of which is provided with an adhesive part 11 for bonding with the face of a small animal; and a top cover 2, which includes a foldable base plate 21 and a sub-plate 22. The base plate is directly or indirectly connected to the base patch, and the sub-plate is provided with a light shield 221. When the sub-plate is folded, the small animal's eyeball is exposed; when the sub-plate is flattened, the small animal's eyeball is located within the light shield. In use, the base patch is adhered to the surface of the small animal's body, specifically the eyelid area, through the adhesive part. When eye drops need to be applied, the folded sub-plate is opened to expose the small animal's eyeball. In the normal state, the sub-plate is flattened. The base plate of the top cover and the base patch can be directly glued together, and the sub-plate and the base patch can be glued together with Velcro, which also achieves folding and flattening.

[0023] In this embodiment, as shown in the figure, the base patch includes a concentric first ring 12 and a second ring 13. The first and second rings enclose each other to form a connected annular groove 14 and a gap groove 15. The gap groove allows air to flow into the annular groove. The gap design is to allow oxygen to pass through, increase oxygen levels, and prevent corneal hypoxia caused by airtightness. The base patch is designed as two parts, upper and lower, rather than a single piece, to match the skull growth of the animal during its growth process and to accommodate facial elongation.

[0024] In this embodiment, as shown in the figure, an intermediate ring 3 is also included, the bottom end face of which is detachably connected to the bottom adhesive. In this embodiment, the top cover installed via the intermediate ring can be completely removed or folded, providing another implementation method.

[0025] The specific steps for wearing a device with an intermediate ring are as follows. 1. First, use a pet grooming clipper to shave the fur around the animal's eyes; 2. Apply body adhesive to the area around the eyes, and then attach the two parts of the base sticker to the upper and lower eyelids respectively; 3. Then attach the middle ring to the bottom sticker using Velcro; 4. The top cover and the middle ring are glued together, with the glue applied to the protrusions of the second half ring and the first half ring; Taking guinea pigs as an example, as the preferred solution, the outer diameter of the base sticker should be 3cm. If it is too large, it will not be secure; if it is too small, it will not stick tightly. The inner diameter should be 1.5-2cm. The lower part of the base sticker should have a fan shape of 180°, and the upper part should have a fan shape of 170°.

[0026] As a preferred option, the outer diameter of the middle ring is 3cm and the inner diameter is 2.5-2.8cm. If it is too large, it will not stick firmly, and if it is too small, it will easily fall off. The lower part of the middle ring has a fan shape of 180° and the upper part has a fan shape of 170°.

[0027] As a preferred option, the top cover is a black opaque sheet, a frosted sheet, or positive and negative lenses of different materials, with an outer diameter of 3cm and an inner diameter of about 2cm. The light shield with the protruding structure is to prevent some animals' eyeballs from bulging and to prevent the sheet from scratching the cornea during movement.

[0028] In this embodiment, as shown in the figure, the bottom end face of the intermediate ring is detachably connected to the bottom adhesive via a Velcro structure.

[0029] In this embodiment, as shown in the figure, the intermediate ring includes a first half-ring 31 and a second half-ring 32. The first half-ring is detachably connected to the first ring body, and the second half-ring is detachably connected to the second ring body.

[0030] In this embodiment, as shown in the figure, a portion of the first half-ring is fixedly connected to the substrate.

[0031] In this embodiment, as shown in the figure, the first semi-ring is provided with a boss 311, which is fixedly connected to the substrate. It can be bonded with adhesive.

[0032] In this embodiment, as shown in the figure, the second half-ring is fixedly connected to the sub-piece. When the sub-piece is folded, it will lift the second half-ring, and the second half-ring and the second ring body are connected by a Velcro structure.

[0033] In this embodiment, as shown in the figure, a crease groove 24 is provided between the substrate and the sub-sheet to facilitate folding.
