In the technique scheme, the material of described inner shell left side wall is a lead glass.
Experiment set-up procedure: at first open the left wall of inner shell, the tumor locus of tumor-bearing mice is pulled out by described through hole, close inner shell left side wall, and utilize hasp and inner shell sealed; The shank that then tumor-bearing mice is stretched out inner shell is fixed on the fixed leg on the flat board; The inner shell that tumor-bearing mice will be housed then pushes shell, and determine that according to the build of tumor-bearing mice inner shell pushes the degree of depth of shell, inserting bolt and screwing in snib groove and screwed hole is completely fixed shell and inner shell at last, begins to carry out the local irradiation experiment of tumor-bearing mice.
Because the technique scheme utilization, this utility model compared with prior art has following advantage:
1. inner shell of the present utility model can freely be twitched in the enclosure, so can adjust the relative position of inner shell and shell according to the build of tumor-bearing mice, and utilize snib that both are completely fixed, tumor-bearing mice can not be free movable in fixture, mice is fixed in the experiment, improves the efficient and the quality of irradiation experiment.
2. shell of the present utility model is made by lead glass, can play good shield effectiveness to the normal position of the tumor-bearing mice that is positioned at inner shell, and other positions of protection mice are not subjected to the influence of X ray under to the situation of tumor-bearing mice local irradiation.
3. this utility model is provided with air-vent, can guarantee the eupnea of tumor-bearing mice in experimentation.
4. this utility model is lined with rubber blanket at the edge of through hole, stops the poor skin of He Liuchu to be scratched because of tractive and friction in the irradiation experiment.
