Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, and in particular to a mouse form deprivation myopia modeling device. Background Technology

[0002] Animal experiments refer to scientific research conducted in a laboratory using animals to gain new knowledge or solve specific problems in fields such as biology and medicine. Animal experiments must be conducted by or under the guidance of trained personnel with research degrees or professional technical skills.

[0003] Form deprivation myopia is currently the most commonly used animal model of axial myopia and an important model in existing myopia research. It involves suturing the eyelids or using a non-contact, semi-transparent eye patch to cover the eyes, depriving the retina of clear vision and reducing retinal image quality to produce significant myopic changes, thus creating an animal model of axial myopia. This is currently the most common animal modeling method in myopia research. There are three main types of existing form deprivation myopia modeling devices: semi-transparent eye patch-neck collar type, skull-fixed lens frame type, and face mask type.

[0004] The semi-transparent blindfold-collar device consists of two main components: a blindfold and a collar. Its main drawbacks are: the collar can easily strangle animals, and the size cannot be adjusted according to the animal's body shape; the blindfold needs to be fixed with adhesive, which is not only easy to fall off, but the adhesive can also irritate the eyes.

[0005] The skull fixation lens frame structure is the most complex and the most difficult to manufacture on your own. Its main components include a skull fixation frame, a lens frame, a lens, and a transparent nail plate. The composition is complex, each component is highly specialized, and the technical difficulty is too high to manufacture on your own.

[0006] In a mask-type device, the mask covers the animal's head and neck, leaving the left (or right) eye, nose, mouth, and ears exposed. This device not only deprives the covered eye of its form perception but also its light perception function. The mask has high requirements for size and is prone to falling off or shifting. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mouse form deprivation myopia modeling device.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A mouse form deprivation myopia modeling device includes a collar, which has a trumpet-shaped structure. The surface of the collar has multiple perforations, and the collar has tie wires inserted into the perforations at the front and back positions. The tie wires at the front end of the collar are wound to form two frames, and an eye mask is snapped into the inside of one of the frames.

[0010] Preferably, the two frame rings are distributed in a figure-eight shape.

[0011] Preferably, the goggles have a hemispherical structure.

[0012] Preferably, the surface of the goggles has a frosted texture.

[0013] Preferably, the end of the collar is provided with Velcro for fastening.

[0014] Preferably, the inner layer of the collar is provided with a protective pad.

[0015] Preferably, a protective sleeve is provided on the outside of the tie wire at the rear end of the collar.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model has a simple structure and is easy to manufacture. It only deprives the sense of form without affecting the sense of light. All materials and tools used are everyday items. Specifically, the eye mask is fixed with wire to solve the problem of eye masks being difficult to fix and easy to fall off, avoiding new irritation and damage caused by using glue. The wire connects and combines the eye mask with the collar, and the size and tightness can be adjusted at any time. In order to avoid abrasion and strangulation caused by long-term wear, a small piece of cloth is sewn on the inner edge of the collar and fixed with wire and cloth cover. The small piece of cloth is taken from a disposable mask, and the cloth cover is the fixing rope of the disposable mask. Attached Figure Description

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-5 A mouse form deprivation myopia modeling device includes a collar 1, which has a trumpet-shaped structure. The surface of the collar 1 is provided with multiple perforations 8, and the collar 1 is provided with tie wires 3 inserted into the perforations 8 at the front and back positions. The tie wires 3 at the front end of the collar 1 are wound to form two frame rings 6, and an eye mask 7 is snapped into the inside of one of the frame rings 6.

[0026] The two frame rings are arranged in a figure-eight shape.

[0027] The eye mask 7 has a hemispherical structure.

[0028] The surface of the eye mask 7 has a frosted texture.

[0029] The collar 1 has Velcro 5 at its end for fastening.

[0030] The inner layer of the collar 1 is equipped with a protective pad 4.

[0031] A protective sleeve 2 is fitted on the outside of the tie wire 3 located at the rear end of the collar 1.

[0032] Working principle: Eye mask 7 production: Take a disposable plastic dropper (2mL), cut off the hemispherical part of the dropper bulb end, and sand the outer convex surface with sandpaper to make it opaque frosted, thus obtaining the eye mask 7 that interferes with the perception of form. Make evenly dense small holes on the edge to facilitate the connection of the connecting wire 3 through which the eye mask 7 is fixed, so as to achieve the purpose of interfering with the perception of form.

[0033] Collar 1 making: Take 0.6mm thick frosted plastic and process it into a ring with an outer diameter of 7cm and an inner diameter of 2.2cm. Smooth the outer and inner edges of the ring. Cut the ring open and trim the sharp corners of the opening to avoid cutting the animal. Attach cut Velcro 5 (size: about 2cm long and 1.7cm wide) to both sides of the opening. This is used to fasten the ring into a circle and adjust its size. To prevent the Velcro 5 from falling off, sew it in place. Secure both ends of the ring with Velcro 5 to form a trumpet-shaped collar 1.

[0034] Making the protective pad 4: Make small holes evenly along the inner edge of the collar 1, take a small piece of cloth and sew it to wrap the inner edge of the ring to form the protective pad 4 on the inner side of the collar 1 to prevent the animal from being chafed due to wearing the ring for a long time; Make a large number of dense perforations 8 randomly in the remaining area of ​​the collar 1 to facilitate the passing, connection, fixing and adjustment of the binding wire 3.

[0035] Cut two tie wires 3, each about 20cm long. The first wire is used to fix the frosted eye mask 7 and connect it to the collar 1. The second wire is used to fix the collar 1 to the animal. Thread the first tie wire 3 around the perforation 8 on the edge of the frosted eye mask 7. Adjust the eye mask 7 to the middle position of the tie wire 3, and tighten both ends of the tie wire 3 to form a frame 6 structure. Fix the eye mask 7. Twist another frame 6 from one end of the tie wire 3. Connect this component to the collar 1 to form an "eye mask-collar" combination structure where the position of the eye mask 7 can be adjusted arbitrarily. Thread the second tie wire 3 around the small hole on the outer edge of the collar 1, forming an approximately trapezoidal shape with the position of the first tie wire 1. Take the fixing rope of a disposable mask, cut it into four equal parts, and thread it onto the tie wire 3 used above to form a protective sleeve 2 structure to prevent the tie wire 3 from strangling the animal.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
