Abstract
The utility model relates to an experimental animals's euthanasia device, its characterized in that: it includes a carbon dioxide bottle, and the gas outlet of carbon dioxide bottle is through the pipeline and one be pipy suction nozzle and be linked together, the suction nozzle is planted and is communicate on the lateral wall of seal box and with the seal box is inside, set up a gaseous relief pressure valve on the pipeline of the gas outlet of carbon dioxide bottle department. The utility model discloses because the animal euthanasia condition can be observed at any time by the seal box that adopts transparent material to make consequently when carrying out euthanasia. The utility model discloses owing to be provided with gaseous relief pressure valve on the pipeline of the department of the gas outlet at the carbon dioxide bottle, consequently can control the carbon dioxide flow, make carbon dioxide concentration progressively rise, reduce the animal euthanasia time.
Description
Technical field
The utility model relates to the euthanasia device of a kind of laboratory animal, belongs to experimental zoology field.
Background technology
The reinforcement realized protection of animals along with the mankind and the requirement of animal welfare ethics, carry out the industry studied for using laboratory animal, animal euthanasia problem more and more comes into one's own.According to the interpretational criteria of American Veterinary association (AVMA) about euthanasia, animal euthanasia must under ensureing that animal welfare meets the prerequisite of ethics, and to alleviate, laboratory animal is painful carries out euthanasia for principle.
Existing animal euthanasia method mainly comprises pharmaceutical methods, physical method and householder method.Wherein pharmaceutical methods is divided into again Sucked medicine method and non-Sucked medicine two kinds.Sucked medicine method is subject to using comparatively widely because of simple to operate, the advantage such as speed is easily controlled.Carbonic acid gas euthanasia method particularly in Sucked medicine method is owing to being safe from harm to human body, and easy to use, the advantages such as cost is lower have been widely used in it minitype animal experiment, comprise muroid, rabbit and bird etc.The mechanism of action of carbonic acid gas euthanasia method be make laboratory animal direct or indirect anoxic, vital functions neuron to suppress or the neuron of brain activity directly destroys.This method can use in different environments, and can the concentration of regulation of carbon dioxide to control the time of animal unconscious.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of simple to operate, easy to use and can not to the euthanasia device of the laboratory animal that operating personnel work the mischief.
For achieving the above object, the utility model takes following technical scheme: the euthanasia device of a kind of laboratory animal, is characterized in that: it comprises a carbon dioxide cylinder, and the gas outlet of described carbon dioxide cylinder is connected with a suction nozzle in a tubular form by pipeline; The sidewall that described suction nozzle is inserted in seal box is communicated with described seal box inside; The described pipeline at the gas outlet place of described carbon dioxide cylinder arranges a gas pressure reducer.
One and the suitable net-like spacer of its interior size is fastenedly connected in described seal box lower horizontal.
The position of described suction nozzle on described seal box sidewall is higher than animal vertical height.
Described conduit adopts silastic material to make; The diameter of described conduit is 5 ~ 15 millimeters.
Described seal box adopts transparent material to be prepared from.
Carbon dioxide purity in described carbon dioxide cylinder is 99.9%.
The utility model is owing to taking above technical scheme, and it has the following advantages: 1, the utility model is owing to adopting the seal box made of transparent material, therefore can observe animal euthanasia situation at any time when carrying out euthanasia.2, the utility model carries out euthanasia owing to adopting carbonic acid gas, and therefore in whole process, animal can not agonize, and does not have stress reaction to produce, and reaches euthanasia state imperturbably.3, the utility model owing to being provided with gas pressure reducer on the pipeline at the gas outlet place of carbon dioxide cylinder, therefore can control carbon dioxide flow, and gas concentration lwevel is progressively raised, and reduces the animal euthanasia time.4, the utility model is simple to operate, easy to use, cheap.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises a carbon dioxide cylinder 1, and the gas outlet of carbon dioxide cylinder 1 is connected with a suction nozzle 3 in a tubular form by pipeline 2.The sidewall that suction nozzle 3 is inserted in seal box 4 is communicated with seal box 4 inside.The pipeline 2 at the gas outlet place of carbon dioxide cylinder 1 arranging a gas pressure reducer 5, entering concentration in seal box 4 and speed for controlling carbonic acid gas.
In above-described embodiment, in seal box 4 bottom can level be fastenedly connected one with the suitable net-like spacer 6 of its interior size, for excreta barrier that animal is produced because of stress reaction in the bottom of seal box 4, prevent from being infected with on animal bodies.
In above-described embodiment, the carbon dioxide purity in carbon dioxide cylinder 1 is 99.9%.
In above-described embodiment, conduit 2 can adopt silastic material to make, and the diameter of conduit 2 is 5 ~ 15 millimeters.
In above-described embodiment, seal box 4 adopts transparent material to be prepared from, so that the state of observation experiment animal at any time.
In above-described embodiment, the position of suction nozzle 3 on seal box 4 sidewall is higher than animal vertical height.
The utility model in use, first will the animal of euthanasia be needed to put in seal box 4 and seal box 4 be covered tightly, then carbon dioxide cylinder 1 is opened, when carbon dioxide cylinder 1 pressure reaches 5MPa, rotary gas pressure-reducing valve 5 regulation of carbon dioxide enters the flow in seal box 4 and observes animal euthanasia state.If once put into the mouse 20 of body weight about 20 grams, ventilate and can complete euthanasia in 2 minutes, but consider there is the non-euthanasia success of individual animal, therefore advise that mouse will be ventilated 5 minutes, rat will be ventilated and be completed euthanasia in 10 minutes.It is especially noted that the motor activity that carbonic acid gas euthanasia produces after animal unconscious, just reflex activity, not by animal perception.
The various embodiments described above are only for illustration of the utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
