Description

Technical Field

[0001] The utility model relates to the technical field of animal experiments, and particularly relates to a capturing device. Background Art

[0002] Animal experiments refer to scientific research using animals in a laboratory to obtain new knowledge in biology, medicine, etc. or to solve specific problems. The ultimate goal of the development of laboratory animal science is to study the life phenomena of animals themselves and then extend it to humans to explore the mysteries of human life. In the field of life science research, the basic conditions required for experimental research can be summarized as experimental animals, equipment, information, and reagents. Some small experimental animals are raised in the laboratory. When the small animals escape in the laboratory, a capturing device is needed to capture them.

[0003] In animal experiments, animals may exhibit strong evasive or aggressive behaviors due to fear and fright during capture. This not only increases the risk of injury but may also lead to serious physiological stress responses such as increased heart rate, rapid breathing, and elevated body temperature. These stress responses disrupt the normal physiological state of the animals, reduce their immune function, and may even affect the accuracy and reliability of experimental results. In more serious cases, the injuries caused during the capture process may lead to long-term health problems, affecting the behavioral performance and physiological indicators of the animals. Therefore, in animal experiments, delicate capture and handling methods are crucial to minimize the harm and fright to animals, thereby ensuring the scientific nature of the experiment and the welfare of the animals.

[0004] For example, the Chinese utility model patent (CN221382141U) discloses a handheld capturing device for animal experiments, which records: "When capturing an animal, first slide the sealing plate in a direction away from the support frame body to make the opening in an open state. Then, the experimenter can hold the holding part and adjust the position of the capturing cage so that the opening is downward, cover the capturing cage on the animal to be captured, and finally push the sealing plate back to capture the animal into the capturing cage. The capturing cage of the present utility model is more convenient to capture and has a wider application range", and also records: "However, in actual application, since the capturing cage in the prior art is a cylindrical structure, when the animal is at any planar position or a certain corner position, the capturing cage cannot capture it, there are large capturing loopholes, and the practicability is low" technical problems.

[0005] To sum up the above, it can be known that in the prior art, a capture cage is placed on the animal to be captured, and finally the sealing plate is pushed to reset to capture the animal in the capture cage. However, this method has the following technical problems: However, when the device is actually used to capture the animal, the animal will instinctively escape when it senses a threat. The speed and agility of the animal may greatly increase the difficulty of capture, and the practicality of the device is relatively low. For this reason, the present application proposes a capture device to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

[0006] Based on this, it is necessary to provide a capturing device for the above-mentioned technical problems, by squeezing the two connecting plates toward the middle, so that the two plug posts move toward the inside of the movable block, and the restriction between the movable block and the device base is released, and then the movable block is taken out, and the food that the animal to be captured likes is added to the food frame, and then the movable block is put back into the device base, and then the two connecting plates are loosened so that the plug posts can be inserted into the device base for fixation under the action of the first spring elastic force, and the device is placed near the animal to be captured, and the animal can be attracted into the net frame and the net shell by the food, and then the pull rod is pulled to release the restriction on the baffle door, and then the baffle door is covered at the opening of the net shell and the net frame with the assistance of the gravity of the heavy object block, and the animal can be captured. In this process, the animal is attracted into the net frame and the net shell by the food, which avoids the situation that the difficulty of capture increases due to the animal's escape, and the method of attracting the animal into the net frame and the net shell for capture is relatively gentle, and the natural foraging of the animal is used to lure the animal, which can reduce the fright and emergency response of the animal, reduce the abnormal physiological state of the animal due to the fright of the animal, and further lead to inaccurate experimental results, thereby improving the practicality of the device.
