One embodiment of the present of invention, as shown in Figure 1 and Figure 2, the upper side of the mouse body fixed station 1 are additionally provided with to shine
The light source 7 of perspective mouse body is penetrated, the light source 7 is located at the centre position of the upper side of the mouse body fixed station 1.Specifically, this reality
The light source 7 for applying example is the upper side flush of area source, surface of light source and mouse body fixed station 1, and light source 7 is electrically connected to a power source；Have
Conducive to abundant irradiation mouse body, light is concentrated；In addition, light source 7 or point light source.The surface of light source of the light source 7 of the present embodiment is in
Rectangle structure convenient for being irradiated to the larger range of mouse body abdomen, is also applied for various sizes of mouse body；Specifically, surface of light source
Shape and structure can there are many.Specifically, the light source 7 of the present embodiment is yellow light source, under the irradiation of the strong yellow light of penetration power, greatly
The blood absorption yellow light of mouse makes blood vessel at this be in black and can clearly see trend and the position of blood vessel；And syringe needle is light tight,
The trend of syringe needle can be clearly seen under light source perspective；So as to reduce inserting needle difficulty, the accuracy of Nurses inserting needle is improved.Tool
Body, light source 7 or the light source of red light source or other energy irradiation perspective mouse bodies.
One embodiment of the present of invention, as shown in Figure 1 and Figure 2, the upper side of the mouse body fixed station 1 is inclined-plane, opposite
In the inclination angle of horizontal plane be 10 °~40 °；It is advantageously implemented at the optimum puncturing point of abdominal aorta, using syringe, makes needle
Sharp inclined-plane is in 5 °~15 ° angles with abdominal aorta, by the piercing that the centripetal extreme direction of distal end is fast, accurate and stable upward.Specifically, this reality
The inclination angle on inclined-plane and horizontal plane for applying the mouse body fixed station 1 of example is 30 °.It specifically, can be by each edge of mouse body fixed station 1
It is all provided with being set to rounded corner structure, experimenter may be damaged by avoiding the edge of mouse body fixed station 1.
In addition, in addition to technical solution disclosed in the present embodiment, light source 7, power supply for the present invention etc. can refer to this skill
The conventional techniques in art field, and these conventional techniques also and non-present invention emphasis, the present invention herein without detailed
Thin statement.
When using rat aorta fixing device for sampling blood provided in this embodiment, blood was collected, by mouse body fixed station 1
Experimental bench is fixed on, then anesthetized rat, rat is lain on the back and is fixed on mouse body fixed station 1, rat four limbs are fixed on fixation
On component 4, then fixed component 4 is moved, make mouse body fixation；Movable block 1 is moved still further below to suitable position and is passed through
Locking member 6 locks and forms suitable housing groove one, and rat buttocks is made to fall into housing groove one；With being used after routine disinfection
Surgical scissors cut off abdominal cavity along abdomen median line, pull to both sides with haemostatic clamp, gauze wipes exudation blood away, and mobile movable block 23 arrives
Suitable position and the housing groove two being suitble to by locking member 6 and formation, internal organs are pushed in side housing groove two, are prevented
Only internal organs set back, and internal organs interference are reduced, convenient for inserting needle；Light source 7 is opened again, under the irradiation of the strong yellow light of penetration power, greatly
The blood absorption yellow light of mouse makes blood vessel at this be in black and can clearly see trend and the position of blood vessel, under yellow light perspective
The trend of syringe needle can be clearly seen；Then using at 1~3mm of end centripetal at abdominal aortic bifurcation as optimum puncturing point, using 10ml
Syringe makes pinpoint inclined plane upward, with abdominal aorta in 5 °~15 ° angles, by the piercing that the centripetal extreme direction of distal end is fast, accurate and stable,
Slow suction blood.The application reduces inserting needle difficulty as a result, improves the accuracy of Nurses inserting needle, and success rate is high,
Ensure to obtain enough blood.
Embodiment two：
One embodiment of the present of invention, as shown in figure 5, embodiment two is what is different from the first embodiment is that the present embodiment two
Mouse body fixed station 1 is in rectangular parallelepiped structure, and the upper side of mouse body fixed station 1 is horizontal plane, and mouse body fixed station 1 is vertically fixed on tool
Have in 10 °~40 ° of inclination fixed plate 8, make mouse body fixed station 1 inclined.
Embodiment two is identical with the embodiment of embodiment one, unlike, mouse body fixed station 1 is vertically fixed on tool
