Description

Technical Field

[0001] This utility model relates to the field of animal experimental auxiliary equipment technology, and in particular to a mouse irradiation fixator and fixation device. Background Technology

[0002] In the research of radiation medicine and radiation protection, mouse irradiation experiments are frequently required. Generally, for mice receiving the same irradiation dose, researchers anesthetize them and place them in the target area of ​​the irradiator. However, due to individual differences among mice, the anesthesia time varies, significantly reducing experimental efficiency. Existing technology discloses a mouse experimental device, including an operating platform and a mouse fixation tube. The mouse fixation tube is fixed to the operating platform by a fixation device. This existing technology can fix mice in experiments such as tail vein injection and blood collection. However, because the size of experimental mice varies, the internal space of the mouse fixation tube may not perfectly match the mouse's body size. Smaller mice can move freely within the mouse fixation tube, affecting the reliability of the irradiation experiment results. Therefore, to address the above problems and technical needs, a new structure needs to be developed that can improve experimental efficiency while effectively fixing the mice. Summary of the Invention

[0003] The purpose of this invention is to provide a mouse irradiation fixation device and fixation apparatus, which has a simple structure and strong practicality. It can fix the mouse without anesthetizing it during irradiation experiments, thereby improving experimental efficiency and ensuring experimental quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A mouse irradiation fixation device includes a base; a frame is provided on the base; a first through hole is provided on each side of the frame on the base; a positioning element is provided between the two first through holes on the lower surface of the base; and an opening is provided on the side wall of the frame.

[0006] In this invention, the enclosure is used to place the mouse and restrict its range of movement. In practical applications, flexible fasteners such as rubber bands can be used, which are inserted into the opening of the enclosure, with both ends passing through the first through holes on both sides, and then fixed to the positioning component. This works in conjunction with the enclosure to prevent the mouse from moving freely within the enclosure, thus securing the mouse.

[0007] Preferably, the enclosure includes a front baffle, a rear baffle, and two side baffles facing each other; the front baffle, rear baffle, and two side baffles together form the enclosure; the front baffle and side baffles are fixedly mounted on the base; the rear baffle is detachably mounted on the base. The detachable rear baffle facilitates the placement of mice.

[0008] Preferably, the rear baffle has a second through hole; the side baffle has an opening. More preferably, the diameter of the second through hole is 0.3~1.2cm; the width of the opening is 0.2~1.5cm. Even more preferably, the diameter of the second through hole is 0.5~0.8cm; the width of the opening is 0.2~1cm. In practical applications, the mouse's tail can be passed through the second through hole to further restrict its movement; the opening allows a flexible fixing member to bypass the mouse, preventing the mouse from moving freely within the enclosure and thus securing the mouse.

[0009] Preferably, the inner wall of the side baffle is provided with a longitudinal sliding groove; the rear baffle is located within the longitudinal sliding groove. The longitudinal sliding groove is used to fix the rear baffle, so that the rear baffle can be detachably installed on the base.

[0010] Preferably, the mouse irradiation restraint also includes a lead plate; the inner wall of the side baffle is provided with a transverse groove; the upper surface of the front baffle and / or the upper surface of the rear baffle is lower than the position height of the transverse groove; the lead plate is located within the transverse groove. The lead plate is used to shield the irradiation rays. According to the actual irradiation requirements, the lead plate is inserted into the transverse groove to adjust the irradiated part and area of ​​the mouse. The size and specifications of the lead plate are not limited and can be designed as needed. The upper surface of the front baffle and / or the upper surface of the rear baffle is lower than the position height of the transverse groove to facilitate the insertion of the lead plate, while leaving a certain gap between the lead plate and the front baffle and / or the rear baffle to prevent the mouse from suffocating during irradiation.

[0011] Preferably, the diameter of the first through hole is 0.5~1.5cm; the positioning element is a hook. More preferably, the diameter of the first through hole is 0.8~1.2cm. The first through hole allows the flexible fixing element to pass through, so that the flexible fixing element can be fixed on the positioning element to achieve the fixation of the mouse; the shape and size of the hook are selected according to actual needs, as long as it can fix the flexible fixing element, without affecting the realization of the technical effect of this utility model.

[0012] Preferably, the number of frames is multiple. More preferably, the number of first through holes between every two adjacent frames is one. This invention can irradiate multiple mice simultaneously, improving experimental efficiency.

[0013] This utility model also discloses a mouse irradiation fixation device, including the aforementioned mouse irradiation fixator and a flexible fixation component. Preferably, the flexible fixation component is a rubber band. In practical applications, the flexible fixation component can also be other conventional flexible fixation components, such as elastic ropes, as long as they can hold the mouse in place; the flexible fixation component spans the frame, is secured in its opening, and its two ends pass through the first through holes on both sides of the frame, and are fixed to the positioning component.

[0014] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: First, the irradiation experiment does not require anesthesia of mice. Through the cooperation of the frame and the flexible fixation component, the mice cannot move freely within the frame, thus improving the efficiency and quality of the experiment. Second, by setting the longitudinal sliding groove, the rear baffle can be detachably installed on the base, which facilitates the placement of the mice. By setting the transverse sliding groove for the insertion of the lead plate, the irradiated part and area of ​​the mouse can be adjusted, which is highly flexible. Third, this utility model is simple to operate, highly practical, and suitable for fixing mice of various sizes. It can conduct irradiation experiments on multiple mice at the same time, ensuring the consistency of the experiment and improving the efficiency of the experiment. Attached Figure Description
