Description
Technical field
Efficiently taken a blood sample and blood-collecting apparatus the present invention relates to experiment blood taking instrument, more particularly to a kind of size rathole bottom.
Background technology
Eyeground blood sampling (blood sampling of retroorbital venous clump) is one of common blood-sampling method of big mouse, and its general operation method is：
Mouse is fixed with left hand, skin of head is clutched as far as possible, head is fixed, neck both sides are gently oppressed downwards, make the abundant evagination (eye of eyeball
Vena orbitalis posterior clump is congested), the right hand holds glass capillary, and piercing is rotated along endocanthion eye socket rear wall to larynx direction, is pierced into depth and is
2~3mm of mouse, 4~5cm of rat, are moved back later again when feeling to have resistance, are kept horizontal position, are slightly attracted, due to blood pressure and hair
Spy uses, and blood is to flow into glass capillary, after blood volume needed for obtaining, and extracts capillary, if gimmick is appropriate, mouse Yue Kecai
0.2~0.3ml of blood, rat can about take a blood sample 0.4~0.6ml.The method advantage is that blood flow is very fast, and wound is smaller, and healing is accelerated, and is applicable
In the collection of medium blood volume, and the situation of big dead mouse need to be avoided, but had the disadvantage that simultaneously：To the technology of operating personnel
It is required that higher, operation difficulty is larger, poor controllability, and VPV and blood sampling volume are difficult to control, and blood back solidification easily occurs, does not go out
The phenomenon of blood, operation is slightly incorrect, also easily causes larger secondary injury, and big mouse infection rate, blind rate and the death rate are high, it is impossible to
Continuous several times blood sampling is carried out, so as to largely effect on produced quantity and recovery ratio.
To sum up, a kind of efficient, rapid blood connector tool for being easily manipulated specifically designed for big mouse is needed badly, to make up existing adopt
The defect of blood technology, reduction test operation person work difficulty and repeated trauma risk, improve the reliability that test data is obtained.
The content of the invention
To overcome the drawbacks described above that prior art is present, the collection blood the present invention is intended to provide a kind of size rathole bottom is efficiently taken a blood sample
Device, efficiently can easily carry out blood sampling collection blood, operation difficulty bottom, controllability is good using the device, success rate of once taking a blood sample and
Collect blood efficiency to improve.
To reach above-mentioned purpose, the present invention uses following technical scheme：
