Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of animal experiment instruments, and particularly relates to a hyperopia induction device for experiments. Background Art
[0002] Animal vision induction experiments are an important research method for exploring the development and function of the visual system and the pathogenesis of visual diseases such as myopia. Such experiments usually involve artificially manipulating the visual environment of experimental animals (such as mice, guinea pigs, chickens, etc.) to observe its impact on the development of animal vision.
[0003] Common methods such as eyelid suture, wearing diffusing lenses or eye masks are used to block light from reaching the retina. For example, healthy 3-week-old guinea pigs are selected, and generally one eye is covered with a diffusing lens / opaque hood to cause form deprivation. Guinea pigs can obtain myopia of about -6.00D after being induced with a diffusing lens eye mask for about 11 days, and myopia of about -4.00D can be obtained after 4 weeks of induction with an opaque mask.
[0004] However, the above experimental methods are interfered by the living habits of animal individuals during the specific experiment. For example, animals habitually clean themselves, or scratch when their eyelids are uncomfortable after surgery, which is extremely likely to cause infection or tearing of the eyelid part of the experimental subject, affecting the development direction of the visual system of the experimental subject. If the face or hands of the experimental subject are fixed or protected, it will affect the normal eating of the experimental subject. Moreover, the cycle of such experiments is long and the manual workload is large. The conventional technical solutions are relatively complex in the actual experimental process. Therefore, the existing technology urgently needs a technical solution for a hyperopia induction device that does not need to change the visual system of the animal itself to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a hyperopia induction device for experiments to solve the problems in the existing technology.
[0006] To solve the above technical problems, the utility model specifically provides the following technical solutions:
[0007] A hyperopia induction device for experiments includes a barrel body, an annular convex lens for twisting light is sleeved outside the barrel body. The barrel body and the annular convex lens are both made of transparent glass material, and a cavity for accommodating the survival of animals is arranged inside the barrel body. A barrel cover is arranged at the top of the barrel body;
[0008] The diopter of the annular convex lens is 4.0D - 10.0D.
[0009] Based on the preferred scheme provided by a hyperopia induction device for experiments, an annular enclosure is arranged on the barrel cover, and a convex light lens for twisting light is fixedly installed inside the annular enclosure.
[0010] Based on the preferred solution provided by an experimental hyperopia induction device, both the convex lens and the cylinder cover are made of transparent glass material, and the diopter of the convex lens is the same as that of the annular convex lens.
[0011] Based on the preferred solution provided by an experimental hyperopia induction device, both the annular convex lens and the convex lens are detachable.
[0012] Based on the preferred solution provided by an experimental hyperopia induction device, a plurality of ventilation holes for communicating with the cylinder body are provided on the cylinder cover.
[0013] Based on the preferred solution provided by an experimental hyperopia induction device, an embedding ring plate with the same inner diameter as the cylinder body is formed at the bottom of the cylinder cover, and handles are fixedly installed on both sides of the cylinder cover.
[0014] Based on the preferred solution provided by an experimental hyperopia induction device, an annular light belt for changing the brightness inside the cylinder body is arranged between the embedding ring plate and the inner side wall of the cylinder cover.
[0015] Compared with the prior art, the present utility model has the following beneficial effects: The present utility model can avoid the discomfort and infection problems caused by directly suturing the eyelids of the experimental subject, and can also induce changes in the visual system of the experimental subject without restricting the daily life behavior of the experimental subject. This experimental method is closer to the principle of physiological axial hyperopia, thereby improving the accuracy of subsequent visual system research results. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] First, the concepts related to this application will be described below with reference to the accompanying drawings. It should be noted here that the descriptions of the following concepts are only for making the content of this application easier to understand, and do not represent a limitation on the protection scope of this application; at the same time, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. This application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0023] Embodiment
[0024] As Figures 1 to 3 shown, the present utility model provides an experimental hyperopia induction device, which includes a barrel body 1. An annular convex lens 2 for distorting light is sleeved outside the barrel body 1. Both the barrel body 1 and the annular convex lens 2 are made of transparent glass material, and a cavity 11 for accommodating the survival of animals is provided inside the barrel body 1. A barrel cover 3 is provided at the top of the barrel body 1.
[0025] The diopter of the annular convex lens 2 is 4.0D to 10.0D.
[0026] As a further illustration of this embodiment, in the process of a conventional hyperopia induction experiment, the individual living habits of animals interfere with the experiment. For example, animals habitually clean themselves, or scratch when their eyelids are uncomfortable after surgery, which can easily cause infection or tearing of the eyelid area of the experimental subject, affecting the development direction of the visual system of the experimental subject. If the face or hands of the experimental subject are fixed or protected, it will affect the normal eating of the experimental subject. Moreover, since the cycle of such experiments is relatively long, the conventional technical solutions are relatively complex in the actual experimental process. In this embodiment, by placing the animal serving as the experimental subject into the cavity 11 inside the barrel body 1, the light environment around the experimental subject is changed. Specifically, the eye axis is the length of the eyeball from front to back. When the eye axis is too short, after the light passes through the refractive system of the eyeball (including the cornea, lens, and vitreous body) and is refracted, it cannot be accurately focused on the retina but is focused behind the retina, resulting in hyperopia. In this example, by adding an annular convex lens 2 outside the barrel body 1, after the light is refracted by the annular convex lens 2, the landing point of the light entering the eyeball of the experimental subject is changed, and the light is focused behind the retina of the experimental subject. By changing the light inside the barrel body 1 for a long time, the visual system of the experimental subject is induced to change. It should be noted that when light enters a substance with a different light density from one object, the propagation direction of the light will be deflected. This phenomenon is called the refractive phenomenon. The unit representing the magnitude of this refractive phenomenon (refractive power) is the diopter (abbreviated as "D"); a refractive power of 1.0 D is equivalent to being able to focus parallel light on a 1-meter focal length. By adopting the technical solution in this embodiment, the discomfort and infection problems caused by directly suturing the eyelids of the experimental subject can be avoided, and the visual system of the experimental subject can be induced to change without restricting the daily life behavior of the experimental subject. This experimental method is closer to the principle of physiological axial hyperopia, thereby improving the accuracy of subsequent research results on the visual system.
[0027] Further, an annular enclosure 31 is provided on the barrel cover 3, and a convex light lens 4 for distorting light is fixedly installed inside the annular enclosure 31.
[0028] Further, both the convex light lens 4 and the barrel cover 3 are made of transparent glass material, and the diopter of the convex light lens 4 is the same as the refractive power of the annular convex lens 2.
[0029] As a further illustration of this embodiment, in this example, the annular convex lens 2 serves as the carrier of the refractive phenomenon and can change the refraction of most of the light inside the barrel body 1. However, there are still some spaces at the inlet and outlet of the cavity 11 and at the top of the barrel body 1 for installing the barrel cover 3. To prevent the experimental subject from looking directly at the barrel cover 3 with its head up for a long time and failing to achieve the effect of inducing the development of the visual system, a convex light lens 4 is added to the barrel cover 3, and the diopter of the convex light lens 4 is the same as that of the annular convex lens 2 to complete the refractive phenomenon inside the entire cavity 11, making the visual development of the experimental subject more accurate and rapid.
[0030] Furthermore, both the annular convex lens 2 and the convex light lens 4 are detachable.
[0031] As a further illustration of this embodiment, in this example, the diopter of each annular convex lens 2 and each convex light lens 4 is always a fixed value. When the visual system of the experimental subject develops to a certain stage as the experiment progresses, the existing refractive phenomenon in the cavity 11 is insufficient to change the visual system of the experimental subject. Therefore, it is necessary to replace the annular convex lens 2 and the convex light lens 4 to meet the overall requirements of the experiment.
[0032] Furthermore, a plurality of ventilation holes 32 for communicating with the barrel body 1 are provided on the barrel cover 3.
[0033] As a further illustration of this embodiment, the ventilation holes 32 in this example ensure the circulation of air between the cavity 11 and the outside air, enabling the experimental subject to survive in the cavity 11 for a long time. In addition, to ensure the normal survival needs of the experimental subject, it is necessary to supplement the experimental subject with daily food and water, and it is also necessary to keep the environment in the cavity 11 clean and tidy.
[0034] Furthermore, an embedded ring plate 33 with the same inner diameter as the barrel body 1 is formed at the bottom of the barrel cover 3, and handles 34 are fixedly installed on both sides of the barrel cover 3.
[0035] As a further illustration of this embodiment, the embedded ring plate 33 in this example is to increase the contact area between the barrel cover 3 and the barrel body 1, making the connection between the barrel cover 3 and the barrel body 1 more stable, preventing the experimental subject from escaping after hitting the barrel cover 3. At the same time, handles 34 are provided on both sides of the barrel cover 3 to facilitate the extraction of the barrel cover 3 from the top of the barrel body 1. As a preferred solution of this embodiment, the barrel cover 3 and the top of the barrel body 1 can be connected by threads.
[0036] Furthermore, an annular light strip 5 for changing the brightness inside the barrel body 1 is arranged between the embedded ring plate 33 and the inner side wall of the barrel cover 3.
[0037] As a further illustration of this embodiment, a plurality of LED lamp groups with adjustable brightness are provided in the annular light strip 5 in this example to change the environmental brightness of the entire cavity 11, enabling the experiment to generate more data research samples and enhancing the diversity of experimental results.

Any person skilled in the art, without departing from the scope of the technical means disclosed in the content of the present invention, may make some modifications or changes to other equivalent embodiments, but should still be regarded as the same technology or embodiment as the present invention.

The description of the above embodiments is only used to help understand the method and its core idea of the present application. The above is only the preferred implementation manner of the present application.
