Abstract
Description
Technical Field
[0001] This invention relates to the field of animal cage technology, specifically to a rat and mouse cage for radiation experiments. Background Technology
[0002] In animal experiments involving the biological effects of radioactive point source radiation, distance and shielding have a significant impact on the calculation of the radiation dose. Commonly used experimental cages for mice and rats are relatively large, with metal bars on top. Several or even a dozen mice are irradiated together in each cage in groups, which greatly affects the accurate calculation of the radiation dose from the point source.
[0003] Conventional laboratory animal cages have several disadvantages: the metal bars above the cage block some radiation; mice clustered together block some radiation from each other; the radiation source is a point source, and the mice move within a rectangular cage, resulting in a large activity area and varying straight-line distances from the point source, which affects dose calculation; furthermore, based on the required radiation dose in the experimental design, the corresponding exposure time and radiation radius (the straight-line distance between the irradiated animal and the point source) can be calculated. The curvature of concentric circles with different radii will change. To accurately control the radiation dose to laboratory animals, it is necessary to design an animal cage with a relatively fixed activity area and freely adjustable curvature. Summary of the Invention
[0004] The main objective of this invention is to provide a cage for rats and mice used in radiation experiments, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A rat and mouse cage for radiation experiments includes an accordion-style variable-arc single cage. The first end of the accordion-style variable-arc single cage has a male door, and the second end of the accordion-style variable-arc single cage has a female door. The male door has concave slots on both sides, and the female door has mountain-shaped slots on both sides. The concave slots and mountain-shaped slots have isolation plates inside, and the isolation plates have feeding components inside.
[0007] Preferably, the accordion-style variable arc single cage includes several PET plastic sheets with gaps between them, several air holes are provided on the top of the accordion-style variable arc single cage, and insertion points are provided on the top and bottom of the concave slot.
[0008] Preferably, the isolation plate includes a lifting hole, which is located at the top of the isolation plate, and a feeding net is fixedly connected to the center of the isolation plate.
[0009] Preferably, the feeding assembly includes a connecting hook, which is fixed to an isolation plate. One end of the connecting hook is fixedly connected to a water bottle support plate, and one end of the water bottle support plate has a feed inlet.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This invention replaces the metal fence above the rat cage with a material such as plastic that does not affect the penetration of radiation; the width of each cage is suitable for holding one rat (it can be designed to be adjustable, or two fixed widths can be designed according to the common sizes of large and small rats); the curvature of the breeding cage can be adjusted according to the concentric circles formed by the straight-line distance between the point source and the dose, so as to match the circumference of the concentric circles, thereby precisely controlling the irradiation dose.

Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1
[0017] Please see Figures 1-3 The present invention provides a technical solution:
[0018] A rat and mouse cage for radiation experiments includes an accordion-style variable-arc single cage body 1. The first end of the accordion-style variable-arc single cage body 1 has a male door 1.3, and the second end has a female door 1.7. Recessed slots 1.4 are provided on both sides of the male door 1.3, and mountain-shaped slots 1.6 are provided on both sides of the female door 1.7. Isolation plates 3 are provided inside the recessed slots 1.4 and mountain-shaped slots 1.6, and feeding components 2 are provided inside the isolation plates 3. The accordion-style variable-arc single cage body 1 includes several PET plastic sheets 1.8, with gaps 1.5 between the PET plastic sheets 1.8. Several air holes 1.1 are provided on the top of the accordion-style variable-arc single cage body 1, and insertion points 1.2 are provided on the top and bottom of the recessed slots 1.4.
[0019] An accordion-style variable-arc single cage is bent into a fan shape, with the radiating point as the center of the fan. This allows multiple rats and mice to have equal radiating distances.
[0020] Among them, reference Figure 3 As can be seen, in this application, the isolation plate 3 includes a lifting hole 3.1, which is opened on the top of the isolation plate 3, and a feeding net 3.2 is fixedly connected to the center of the isolation plate 3.
[0021] Among them, reference Figure 2 As can be seen, in this application, the feeding component 2 includes a connecting hook 2.2, which is fixed to the isolation plate 3. One end of the connecting hook 2.2 is fixedly connected to a water bottle support plate 2.1, and one end of the water bottle support plate 2.1 is provided with a feed inlet 2.3.
[0022] This invention is a cage for rats and mice used in radiation experiments:
[0023] The accordion-style variable arc single cage 1 is formed by splicing multiple PET plastic sheets 1.8 to form the cage wall. The gaps 1.5 between adjacent plastic sheets are connected by polyester fiber cloth and pressed to form an accordion-style structure. The top PET sheet has ventilation holes 1.1. The male door 1.3 and the female door 1.7 are rectangular openings at both ends of the single cage. A concave slot 1.4 is fixed on each side of the male door 1.3. There are two insertion points 1.2 on the outside of each slot. A mountain-shaped slot 1.6 is fixed on each side of the female door 1.7. Different single cages can be connected to the female door 1.7 through the insertion points 1.2 of the male door 1.3 and the slots on the outside of the female door 1.7.
[0024] The feeding component 2 is formed by bonding together multiple PET plastic plates 1.8 in the shape shown in the figure. It can be fixed to the isolation plate 3 by connecting hooks 2.2. The water bottle support plate 2.1 and the feed inlet 2.3 are both tilted at 30° to facilitate watering and feed feeding.
[0025] The isolation plate 3 is made of PET plastic plate 1.8 in the shape shown in the figure. It is used to insert into the slots of the male door 1.3 and female door 1.7 of a single cage. It is provided with a lifting hole 3.1 for easy insertion and removal of the isolation plate 3. The feeding net 3.2 is made of stainless steel and is fixed at the opening of the isolation plate 3. It can be connected to the feeding component 2 for hooking.
[0026] PET sheets exhibit excellent creep resistance, fatigue resistance, abrasion resistance, and dimensional stability, possessing the highest toughness and high hardness among thermoplastics. As a material for radiation-exposed animal cages, it offers good permeability, facilitating experimental observation while maintaining cage strength. The accordion structure allows for free bending, enabling animals to be distributed within designated intensity arc-shaped areas based on point source radiation characteristics. The male and female door slot design facilitates the free connection of multiple cages. The isolation insert design allows for single-cage isolation or multi-cage connection, facilitating seamless switching between individual and group animal experiments. Furthermore, the isolation insert can be combined with feeding component 2 to provide water and feed to the experimental animals.
