4. Preferably, the semicircular hole communicated with the outside when the support inclines is made of a rubber ring material, so that the tail of the small animal is protected.
5. Preferably, the lifting support takes the rotating transverse shaft as one end fixing pivot, the other end of the lifting support moves up and down through the adjusting rod, and the adjusting rod can be adjusted into four angle gears by selecting the gears of the clamping grooves.
6. The experimental animal can be a nude mouse, a white mouse, a black mouse and other mice.
7. The utility model discloses simple structure, it is with low costs, the usage is wide, and is easy and simple to handle, non-metallic material such as adoption ya keli plastic slab can guarantee to inject, get blood, acupuncture, dynamic enhancement or postpone experiments such as scanning the toy under the condition of continuous anesthesia at multi-angle work and no metal artifact under 9.4T super high field intensity or toy positron emission computer tomography (micro PET/CT). The use effect is good, and the device is an innovation on experimental equipment.
Compared with the prior art, the utility model, have following advantage:
(1) can be used for tail vein injection, abdominal cavity injection, heart blood sampling, acupuncture and moxibustion and the like, and can establish various experimental models.
(2) The small animal is placed on the rectangular fixing frame of the lifting support through the small animal limb fixing bed, the whole-course anesthesia state of the mouse is kept, and the risk that experimenters are scratched and bitten by the small animal can be reduced.
(3) The experiment can be directly carried out under the ultrahigh field intensity of 9.4T or CT, the time is saved, and the method is convenient and fast.
(4) And by adopting a non-metal material, no metal artifact exists under MR or CT scanning.
(5) Dynamic enhancement or delayed scanning can be directly carried out under the anesthesia state, and a plurality of groups of experimental data can be obtained.
