[0002] Rats are one of the commonly used animals in laboratories. In establishing animal radiation models, accurate irradiation areas are crucial.

[0003] Most of the existing rat fixators for irradiation are only suitable for vertical radiation sources. During irradiation with horizontal radiation sources, the animal's body position must be placed sideways (i.e., the animal's back / chest and abdomen are facing the horizontal radiation source). This has the following technical defects: the anesthetized rat cannot be fixed in the center of the device due to systemic weakness, resulting in deviation of the irradiation area.

[0004] Therefore, how to design a device suitable for fixing rats during horizontal irradiation has become an urgent problem to be solved. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a device suitable for fixing rats during horizontal irradiation to solve at least one of the above technical problems.

[0006] The technical solution of the utility model is: a device suitable for fixing rats during horizontal irradiation, comprising a containing chamber, the containing chamber is a rectangular box body with an opening on the top surface, a sliding cover plate is arranged on the opening of the containing chamber, two hollowed-out grooves arranged at intervals are arranged on the bottom plate of the containing chamber, the two hollowed-out grooves are connected by a plurality of Velcro strips arranged at intervals, the two ends of the same Velcro strip are bonded, an experimental mouse is fixed between the Velcro strip and the bottom plate of the containing chamber, and holes for the experimental mouse limbs to pass through are arranged on the vertical plate of the containing chamber.

[0007] The utility model adopts a accommodating bin for placing experimental mice. The Velcro is passed through two hollowed-out grooves and then bonded to fix the experimental mice during horizontal irradiation, thereby achieving precise positioning during the irradiation process, and solving the technical defect that anesthetized rats cannot be fixed in the center of the device due to systemic weakness, resulting in deviation of the irradiation area.

The utility model adopts a storage bin for placing experimental mice, and the Velcro passes through the two hollowed-out grooves and then adheres, so that the experimental mouse is fixed during horizontal irradiation, and accurate positioning during the irradiation process is achieved, which solves the technical defect that the anesthetized rat cannot be fixed in the center position of the device due to systemic weakness, resulting in deviation in the irradiation area.

[0017] Embodiment 2: Based on embodiment 1, a breathing hole 4 is provided on the bottom surface of a side vertical plate of the accommodation chamber 1, and the breathing hole 4 is arranged corresponding to the head of the experimental mouse, and the diameter of the breathing hole 4 is 1 cm semicircular. The utility model adopts a breathing hole arranged corresponding to the head of the experimental mouse, which can accommodate the mouth of the rat, and the head of the experimental mouse can breathe through the breathing hole, preventing the rat from having difficulty breathing or even suffocating to death.

[0018] Embodiment 3: Based on the embodiment 1, a tail fixing hole 5 is provided in the middle of the bottom surface of the vertical plate on the other side of the storage bin 1, and the diameter of the tail fixing hole 5 is 1 cm semicircular, and hind limb fixing holes 6 are provided on both sides of the tail fixing hole 5, and the diameter of the hind limb fixing holes 6 is 0.6 cm semicircular. The utility model adopts the tail fixing hole to expose the tail of the experimental mouse, and adopts the hind limb fixing holes to expose the hind limbs of the experimental mouse, which can separate the various parts of the rat body, which is conducive to the construction of radiation models of different parts.

[0019] Embodiment 4: Based on Embodiment 1, refer to Figure 3 , Figure 4 The Velcro 7 is a long strip structure, with a furry surface 701 on one end surface of the long strip structure, and a hook surface 702 on the other end surface of the Velcro 7. The furry surface 701 and the hook surface 702 are respectively located on both sides of the center line of the cross section of the long strip structure. The Velcro 7 is a 20 cm long and 1 cm wide strap. The utility model adopts a Velcro with a long strip structure, with the furry surface located on one end surface of the long strip structure, and the hook surface located on the other end surface of the long strip structure. The furry surface and the hook surface are respectively located on both sides of the center line of the cross section of the long strip structure. The Velcro passes through the bottom. After the Velcro is wrapped around the rat and the fixing device for one circle, the furry surface and the hook surface at both ends of the long strip structure can be fitted and fixed, and fixed to the chest and abdomen of the rat according to the body shape of the rat, so as to fix the experimental rat.
