Abstract
Description
Technical Field
[0001] This utility model relates to a rabbit fixation device with rabbit ear fixation function, which belongs to the field of experimental instruments in medicine and biology. Background Technology
[0002] Animal experiments are an indispensable part of scientific research, used to explore the laws of life, verify scientific hypotheses, and promote the healthy development of human society. Currently, animal experiments are applied in various research fields, such as establishing models through gene editing or environmental factors to simulate the occurrence and development of human diseases; verifying the safety and efficacy of drugs; and studying basic biological processes such as cell metabolism. Laboratory rabbits, with their moderate size, short reproductive cycle, docile temperament, clear and abundant ear veins, and sensitivity to various antigens, are widely used in teaching, research, and other experiments.
[0003] Studies on laboratory rabbits often involve procedures such as injecting anesthetic into the marginal ear vein, collecting blood from the marginal ear vein, and injecting contrast agents into the marginal ear vein. When the needle tip pierces the marginal ear vein, the laboratory rabbits often struggle violently due to the irritating pain, making the operation difficult to carry out smoothly, affecting the subsequent experimental process and efficiency, and thus affecting the stability and accuracy of the experimental results.
[0004] Currently, procedures such as administering anesthetic via the marginal ear vein in experimental rabbits require at least two personnel. One person stands at the rabbit's tail, holding the ears with both hands and gently bending them forward, supporting the rabbit's body with their elbows on either side and gently pulling them inward to stabilize the rabbit's head and body, while leaning slightly forward to limit the rabbit's range of motion. The other person stands at the rabbit's head, using one hand to stabilize the bent ear and the other to hold the syringe and perform the procedure. When the rabbit feels pain, it will struggle and shake its ears, making needle insertion difficult and potentially causing injury to the personnel, thus posing a safety risk. Utility Model Content
