Description
Technical field
The utility model belongs to a kind of experiment equipment technical field, and in particular to a kind of adjustable rat fixator.
Background technique
Rat is conventional zoopery object, because its disposition is violent, aggressiveness is strong, is easy to be difficult to fix due to enraging.Greatly
The fixation of mouse is the basic demand of experiment, common experimental implementation such as: tail vein injection and blood drawing, the pressure measurement of big rat-tail all need
Fix the cooperation of rat.If the dosage not only anaesthetized is difficult to control with anesthetized rat to reach fixed purpose, cause animal dead
Die rate height, it is most important that the accuracy that will affect experiment violates the preciseness of scientific research.How under the premise of safe and feasible,
The every pilot project for smoothly completing rat is the problem of experiment primarily faces.
Rat experiment in, tail vein puncture blood collecting or injection be common method, have damage it is small, stress reaction is few,
It the advantages such as can be repeated several times in a short time.In order to reduce the influence to experimental data and facilitate the operation of experimenter, generally require
It keeps the waking state of rat and is fixed well, carry out puncture procedure after rat-tail is drawn.Rat currently on the market is solid
Determining device mostly is made of organic glass or stainless steel material, and monomer structure, fixed site is more, and experiment will repeat same every time
Fixed operation, increase the labor intensity of operator, waste experimental period.And mostly based on tubbiness, space envelope
It closes, has a single function, it is big to the nocuity of rat, do not meet the principle and experimental animal ethics of 3R (reducing, substitution, optimization)
It learns and requires.Existing tubbiness fixator cannot usually agree with very well with the figure of different weight rat, make because its model is fixed
Feel oppressed at rat and suffocates, it is also possible to so that rat is turned experiment operator of biting, not only influences conventional efficient and accuracy,
Also increase the risk of experiment operator injury.It is single additionally, due to fixator model structure and function, a part can only be carried out
The unicity of rat is tested, and the requirement of experiment for covering each figure rat cannot be played, also need to purchase other kinds of fixator into
Row experiment, increases experimental cost and resource consumption.
There are also rats to test with device, such as Chinese patent " CN205866887U " is fixed at present, is tied up with velcro
Bring the fixator of fixed rat, can not solve the problems, such as rat be easy stress in the environment of be easy to shake off；Chinese patent
It is netted that the device that " CN205459183U " is announced is set as cylinder, and stress reaction easily occurs when entering fixator for rat, scratches net
Shape fixator and keep experimental mouse injured, Reusability rat is not easily accessible after forming memory；Chinese patent " CN201578395U "
The device announced only has the flexibility of fore-aft travel；The device that Chinese patent " CN206324878U " is announced is all adjustable big
Rat holder, but since the fixation device includes that fixed station and right-angled intersection hole and isolated head holder and four limbs are solid
Determine device and increase operation sequence, serves as operation more difficulty, reduce conventional efficient.
