Description
Technical field
The present invention relates to animal experiment technique field, especially a kind of fixation in the test of meiofauna inhalation anesthesia
Device.
Background technique
In the experiment that (> 0.5h) exposure influences rat/mouse for a long time of research Inhalation Anesthetic, it is bound to relate to
And the problem of arriving exposing device, can keep dynamic when conditions permit in the exposure experiment of common inhalation anesthetic
The autonomous respiration of object and avoid carrying out trachea cannula or tracheotomy to animal carrying out mechanical ventilation.At present mainly by by petty action
Object is placed directly in a transparent closed anesthesia case, then is passed through anesthetic gases and is anaesthetized to animal, this anesthesia method
It can be very good to guarantee that animal is autonomous respiration anesthesia, but experimenter is difficult effectively to verify whether that anesthesia is completed, and anaesthetizes journey
Depth is spent, is equally easy to cause experimental data inaccurate, even results in that animal is directly dead, closed anesthesia case is also difficult to make
User detects animal stress reaction in anaesthesia process, needs to open cabinet and is detected, this detection mode is very
It is cumbersome, it anaesthetizes not in place, it is also necessary to be re-closing off cabinet, then be passed through anesthetic gases, guarantee the concentration of anaesthetic, and unpack and examine
It surveys, equally the anesthetic gases in cabinet can be made to leak, experimenter may be impacted, influence conventional efficient.Passing through will
Toy part such as head, the mode anaesthetized into anaesthetic room, animal would generally acutely struggle, need in order to avoid struggling
Animal foot is fixed, but fixed operation is also very complicated, reduce conventional efficient, cannot guarantee that toy can be with
Anesthesia well.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of meiofauna anesthesia test case with fixed device,
Structure is simple, can effectively anaesthetize to meiofauna, while animal body can be exposed to outside anesthesia case, facilitate experimenter
Stress tests are carried out to object of experiment.
The present invention provides a kind of meiofauna anesthesia test case with fixed device, including anesthesia case, empty oxygen gas mixture
Body tank and anaesthetic Volatile anesthetic, the sky oxygen gas mixture tank and anaesthetic Volatile anesthetic pass through gas-guide tube respectively and are connected and set with case is anaesthetized
