The specific embodiment
Embodiment 1: shown in Fig. 1,2,3,4, this device is that a cylindrical tube of being made by transparent material constitutes, and cylindrical shell is made up of openable upper and lower two parts, and the logical lateral loose-leaf 3 of upper and lower two parts connects.Cylindrical shell top be divided into again size renovate 1 before identical, after renovate 2 two parts, when opening, precedingly renovate 1, after renovate 2 and can turn up to 135 °.Before renovate 1, after renovate 2 and link to each other with the cylindrical shell lower part by loose-leaf 3 respectively, before renovate 1, after can forward and backward lid be connected into an integral body by intermediary hasp 4 between renovating 2, also can separately become independent two parts, thus select cylindrical shell top before renovate 1, after renovate 2 closed respectively or closed simultaneously.Cylindrical shell lower part holder with before renovate 1, after renovate 2 closed contact positions buckle 5 arranged, the upper and lower two parts of cylindrical shell can tighten upper and lower two parts locked by buckle 5 when closed, after the buckle closure, need to open big rat holder 17 by pressed by external force buckle 5.Renovate 2 inwalls behind the cylindrical shell and be connected with one and press Mus plate 6, the front of pressing Mus plate 6 by reed 7 with after renovate 2 inwalls and link to each other; Renovate 2 1/3rd places, middle back behind the cylindrical shell, have the pressure Mus plate that passes barrel to regulate bolt 8, scalable is pressed the position of Mus plate 6, makes to press fixedly rat tail back of Mus plate 6.Before renovate 1 correspondence the cylindrical shell lower part be connected with Mus cephalostat 9, Mus cephalostat 9 is vertebral body vacancy cylinder for the centre, and is thin before the vacancy, is connected with Mus diet hole 10, for the rats eating drinking-water of closing in big rat holder 17; After gradually thick, coincide with the Mus head shapes.Mus cephalostat 9 is fixed with cylindrical shell by the hold-down nut 11 of cylindrical shell side-lower, after unscrewing hold-down nut 11, can move forward and backward Mus cephalostat 9, to adapt to the not long rat of consubstantiality, hold-down nut 11 is fixedly moving forward and backward in the chute 15, with the fixing Mus cephalostat 9 of diverse location.There is elliptical aperture 12 at/3rd places, middle back of cylindrical shell lower part, are used for carrying out lumbar injection to experiment with rat, also can ventilate; The terminal both sides of cylindrical shell lower part have fixedly rat lower limb of lower limb holddown groove 13 respectively, are convenient to carry out the various operations at rat lower limb position; There is defecate groove 14 at the terminal middle part of cylindrical shell lower part, is beneficial to the rat defecation, simultaneously can be from here fixing rat root of the tail portion, be convenient to afterbody operations such as caudal vein puncture.Below the big rat holder 17 vertebral body base 16 is installed, can big rat holder 17 be installed in above the slot 20 above the support 21 by vertebral body base 16, vertebral body base 16 and slot 20 have good coincideing.Can arrange a plurality of slots 20 on the support 21, can set up a plurality of big rat holders 17, carry out the weightless operation of ground simulation of a plurality of rats simultaneously.Support 21 crossbearers are falling on " T " cabinet frame 19, and " T " cabinet frame 19 that falls at two ends is fixed on the base 18.Support 21 terminal with fall " T " cabinet frame 19 junctions protractor 22 arranged, the angle of inclination of big rat holder 17 can read out on protractor 22 by pointer 23; Be convenient to carry out the weightless research of ground simulation of aerospace medicine field differing tilt angles.Vertebral body base 16 and slot 20 are supporting to be fixed to big rat holder 17 on the support 21, and other structure that can reach fixed effect all can; If reed 7, pressing the Mus plate to regulate bolt 8, it's not true also Mus can be pressed onto in the holddown groove, but can't be applicable to the rat that various bodies are long, hold-down nut 11 and fixing chute 15 with reed 7, press Mus plate adjusting bolt 8 effects identical.Reed 7 can adopt " fixed pressure Mus plate " to substitute with pressing Mus plate adjusting bolt 8, will press Mus plate 6 to be fixed on " afterwards renovating " medial wall, omits this two structures, presses Mus plate 6 positions but can not regulate, and fixedly the effect of rat is also bad.Hold-down nut 11 can adopt the mode of " push and unlock " to fix.Vertebral body base 16 and slot 20 can adopt mode such as Magnet absorption to substitute, but fixed form is insecure." T " cabinet frame 19 that falls can adopt tripod to replace.
This utility model is not limited only to this embodiment 1, be connected the big rat holder 17 on the swinging mounting 21, can also be other big rat holders simple in structure, as long as it is connected and composed with renovating by holder, renovate on one side and be rotationally connected with holder, another side and holder snapping or clamping just can be closed rat very easily and be fixed in the stationary magazine creel.
