for closing height is turned up on the position in hole 34, and the leg that the height of such fixed feet handcuff 32 just adapts to experimental animal is long, uses phase Same method successively fixes other three legs and feet of experimental animal；It can start to perform the operation after being ready to, when experimental animal is faced upward Face is placed in when accepting on trampoline 28, when four limbs are fixed in the fixed feet handcuff 32 on wide lofty tone bar 5, the back of experimental animal with Figure shape is supported by the strong elastic of undertaking trampoline 28 will not sink to touching to accept 7 inner surface of groove, in surgical procedure Bleed with sewage flowed to through the gap for accepting trampoline 28 it is real without polluting in the liquid collector groove 8 for accepting 7 bottom of groove The body of animal is tested, manually-operated gate 10, the drain pipe 9 for flowing to sewage and being controlled by manually-operated gate 10 automatically of bleeding collected are opened It prevents from polluting in following waste collection bucket 11；The spine that the release of ratchet snap-fastener 3 is stuck in ratchet snap-fastener 3 is pressed with hand after the completion of operation Then eye-splice belt 1 in tooth takes out the legs and feet of experimental animal in the handcuff foot groove 31 in arc handcuff frame 27, use is identical Method successively from inner other three legs and feet for taking out experimental animal of handcuff foot groove 31 in arc handcuff frame 27, thus can be The experimental animal performed the operation is taken off from the Surgery Platform 17 of portable experimental animal operation fixing device, does in next step Experimental analysis；Then the undertaking groove 7 and liquid accepted below trampoline 28 on Surgery Platform 17 are rinsed with cleaning solution and clear water Body collector groove 8, by the waste liquid of waste collection bucket 11 down to the place of dedicated waste collection after cleaning up, and by waste collection bucket 11 clean up, then carry out disinfection to whole device；Wide deflection wheel 16 will be adjusted to reset, unclamp the support member below Surgery Platform 17 The foot brake 14 of the movable castor 19 for the movable branching rod 23 that 22 four Angle Positions are installed respectively, portable experimental animal is performed the operation Fixed device shifts storage onto or reuses the place of this device, and foot brake 14 is checked, and makes entirely to fix device holding stabilization And it is immovable.
