Description
Technical field
This utility model relates to a kind of device for detection of animal oxygen consumption.
Background technology
When the Repiration mechanism on animal is studied or when screening has the respiratory medicine of impact, usually need to carry out the mensuration of toy anoxia enduring and oxygen consumption index.
Existing toy anoxia enduring experimental technique adopts single ground wide mouthed bottle to make anoxia bottle, wherein add appropriate sodica calx to cook carbon-dioxide absorbent, laboratory animal is put into bottle, toy is because Repiration is carbon dioxide and being absorbed by sodica calx by the oxygen conversion in bottle, required time while measuring toy death by suffocation.The method only can be measured toy the survival time under hypoxic condition, can not measure its oxygen consumption, the resisting oxygen lack in the time of cannot understanding processing mode or handled thing and act on toy and the relation of oxygen consumption.Through improved method, be that mercury gauge is connected with anoxia bottle on its basis, thereby the carbon dioxide that records toy exhalation is absorbed the negative pressure being produced by sodica calx, but the result that the method records is mercury column millimeter, need more complicated conversion and date processing, and can not directly measure oxygen consumption.
Utility model content
The purpose of this utility model is to provide a kind of device for detection of animal oxygen consumption.
The device for detection of animal oxygen consumption that this utility model provides, comprises feeder, animal arranging device, oxygen consumption checkout gear, conduit first and conduit second;
Described animal arranging device is air hermetic, comprises box body 1, the lid 2 mating with described box body and the filled media 4 with absorbing carbon dioxide function, and described filled media is located at the bottom of described box body, and described lid is provided with two through holes;
