Description

Technical Field

[0001] The utility model relates to the technical field of euthanasia equipment, in particular to an experimental rabbit euthanasia equipment. Background Art

[0002] The existing methods of euthanasia for experimental rabbits mainly include the following: drug injection, inhalation (halide anesthetics or carbon dioxide), cervical dislocation after anesthesia, penetrating spring gun, and non-penetrating spring gun. The problems with the existing methods are as follows:

[0003] The drug injection method needs to be used in conjunction with sedatives or local anesthetics and analgesics to relieve the pain of animals. If the combination is not reasonable, it may cause the animals to suffer death pain and fail to achieve the purpose of euthanasia. The inhalation method requires inhalation anesthetics or carbon dioxide for inhalation euthanasia. The dosage of anesthetics, or the concentration and flow rate of carbon dioxide, etc., need to be strictly controlled. It must be supplied in the form of precise regulation and purification, which is strict and costly. The cervical dislocation method is easy to cause experimental personnel to make mistakes in operation because the experimental rabbits are large in size and have well-developed neck muscles. There is even a phenomenon that the experimental personnel lack experience in the technique, which may lead to multiple unsuccessful cervical dislocations. Such unqualified operations do not meet the requirements of experimental animal ethics. During the use of the penetrating spring gun, the operator should use the non-inertial hand to press the shoulder blade to secure the rabbit, and the thumb and index finger should be placed lightly on the rabbit's neck. The use of these devices will be visually unpleasant, usually causing environmental pollution, and the operator must be trained before operation. Non-penetrating spring guns may cause animals to be stunned if used improperly, and may affect the examination of brain diseases after the animals are euthanized. Utility Model Content
