Device for executing experiment rabbits

Abstract

The invention relates to a device for executing experiment rabbits. The device for executing the experiment rabbits comprises a base board, a sliding table, a handle, partition boards, a base, a connection rod, a push rod, a wing screw, a push rod support, a pedal, a crank, rabbit neck clamps, a rabbit neck clamp support A, a rabbit neck clamp support B and wing screws with anti-skid teeth, wherein the sliding table is embedded into the base board through a guide rail, both the base and the rabbit neck clamp support A are fixed onto the base board by screws, the two partition boards are connected with two sides of the base board in an inserted mode, the handle, the rabbit neck clamp support B and the push rod support are all fixed onto the sliding table by screws, the connection rod is connected with the push rod and the crank, the crank is connected with the base through a shaft, the push rod is sleeved with the base and the push rod support sequentially, the wing screw is connected with the push rod support, the crank is sleeved with the pedal, and the two rabbit neck clamps are connected with the neck clamp support A and the rabbit neck clamp support B through the wing screws with the anti-skid teeth respectively. By means of the device for executing the experiment rabbits, cervical vertebrae of the experiment rabbits can be dislocated to instantaneously execute the experiment rabbits, the execution time is shortened, unnecessary pain and fear of the experiment rabbits are eliminated, and accidental injuries or self-injuries of laboratory technicians are avoided.

Description

technical field [0001] The invention belongs to the technical field of animal experiments, and in particular relates to a device for killing experimental rabbits. Background technique [0002] At present, the methods of killing experimental rabbits in medical biological experimental research are mainly divided into two categories, one is drug killing, including injection of anesthetic or toxic preparations, or inhalation of excessive volatile anesthetic preparations through the respiratory tract, causing excessive nerve center hyperactivity. Inhibition, lethal by hypoxia. The other is to execute them by physical and mechanical methods, including the following: first, a large amount of air is injected through the ear veins, causing air embolism to form in the heart and lungs, resulting in circulatory obstruction, and death from shock; second, Violence was used to beat the rabbit's skull, and the brain was damaged and died; the third method was to cut off the aorta, causing a...

AI Technical Summary

Problems solved by technology

[0003] Drug killing method, the experimental rabbits have to go through a long period of death process, the efficiency is low, and due to the differences in the physiological conditions of the individual experimental rabbits, it is impossible to accurately grasp the dosage of the drug, and it is easy to overdose in practice, causing unnecessary waste and increasing costs It may even pollute the environment, or cause incomplete execution due to insufficient medication, making the experimental rabbits suffer from death for a longer period of time

In addition, the drug killing method has its limitations. The killing drugs will inevitably affect the physiology, pathology, tissue structure, cell morphology, etc. of the experimental rabbits. Experimental items for the research of the above indicators

[0004] Although the physical and mechanical killing method has a wide range of applications, the experimental rabbits have to suffer great physical pain and die. cause great pain

The specific discussion is as follows. The air embolism method is likely to cause the failure of the first venipuncture for experimental rabbits with small body size and unclear venous dissection. For experimental rabbits with strong body size, it is easy to cause insufficient air injection at one time and incomplete execution. In both cases, it is necessary to puncture the experimental rabbit multiple times before it can be executed; in the violent beating method, due to the lack of strength of the operator or the inaccurate control of the beating position, multiple beatings are required to kill the rabbit.

In addition, in order to prevent the experimental rabbit from struggling during the physical and mechanical killing process, it needs to be fixed on a certain platform with ropes, which will undoubtedly increase the fear of the experimental rabbit, and there are also potential safety hazards. Large and powerful, if the experimenter has insufficient upper limb strength and poor control, they will be easily injured by the experimental rabbit, or self-injured in operations such as sharp needle puncture, sharp knife cutting, and blunt instrumental beating

[0005] To sum up, the existing methods of killing experimental rabbits have varying degrees of defects, and violate the ethical requirements of humanely killing experimental animals

Secondly, in order to be proficient in the skills of killing experimental rabbits, the experimenters need to undergo long-term training. After experiencing such violent, bloody, and painful animal executions many times, it will also have a negative impact on the experimenter's psychology.
