[0002] The experimental rabbit form deprivation myopia model is a common model used in the fields of ophthalmology and optometry to study the mechanism, prevention and treatment of myopia, and is widely used in scientific research. The common method for preparing the model is partial eye patching, which is completed by eyelid suturing or eye patch pasting. Although both methods are widely used, there are still certain disadvantages in the actual operation process.

[0003] The traditional eyelid suturing method needs to be performed under anesthesia. It is an invasive surgical procedure with high requirements for aseptic operation. Bleeding, tissue damage, and eyeball infection are prone to occur during and after the operation. The eyeball is completely covered by a patch to form a closed environment, which is prone to hypoxia and eyelid and ocular surface infection. When wearing a traditional eye patch, the experimental rabbit needs to cut the hair around the eyes and stick the patch on the skin. However, the experimental rabbit is large in size and has strong hands and feet, so it is easy to scratch the patch and it will fall off. Wearing an Elizabethan collar can easily increase the discomfort of the experimental animals and cause difficulty in eating. In addition, once the traditional eyelid suturing method and the eye patch covering method are fixed, it is inconvenient to open the eyelid and cover the eye patch at any time, and it is not convenient to explore high-frequency intervention measures, such as daily eye drops and high-frequency light exposure.

The utility model is a head cover for modeling form deprivation myopia based on the outline of a young rabbit, and is used for young rabbits aged 2-3 weeks and weighing 0.3-0.5kg. Before use, attention should be paid to the actual size of the experimental rabbit. The eye mask body 5 and the head cover have a certain durability and can be recycled.

[0025] The headgear is mainly made of space cotton, which is cheap, non-toxic, easy to obtain, and breathable, which can ensure air circulation on the covered eye surface, and has both firmness and wearing comfort; the base 4 and the eye mask body 5 are made of resin material 3D printing. The material itself is non-toxic and inexpensive, safe for experimental animals, and has a certain strength and is not easily deformed by compression. The eye mask body 5 is not completely light-transmissive and has a modeling effect. In order to adapt to the head structure of the experimental rabbit, the base 4 and the eye mask body 5 are designed with reference to the rabbit skull structure, and have a certain curvature, which can fit the head of the experimental rabbit and reduce the chance of the eye mask falling off due to animal scratching.
