more preferably, offer the through hole extending along the vertical direction on the outer end of described fixture, described depression bar is slidably located in described through hole vertically, and described locking piece is radially pressed on described depression bar in the circumferential side wall of described through hole.
preferably, described root fixings is for Mus tail being pressed on to the primary and secondary adhesive tape on described extensible member.
preferably, described end fixture is the alligator clamp for extensible member described in clamping and Mus tail end.
more preferably, on described alligator clamp, be provided with cushion for the clamping part that clamps Mus root of the tail portion.
preferably, the top of described cage tool has the top cover that metal material is made.
preferably, described cage tool is transparence, offers multiple and air-vent its intracavity inter-connection in the circumferential side wall of described cage tool.
due to the utilization of technique scheme, this utility model compared with prior art has following advantages: this utility model fixing device for vena caudalis injection of mouse in use, first mice is placed in to cage tool, then from cage tool opening part, Mus tail is stretched out, use successively root fixings from Mus root of the tail portion to Mus tail end, hold down assembly, end fixture is fixed on Mus tail on extensible member, root fixings and holding down assembly near Mus root of the tail portion, end fixture is near Mus tail end, multiple spot is fixed, good fixing effect, can allow one man operation to inject, this apparatus structure is simple, easy and simple to handle.
Brief description of the drawings
accompanying drawing 1 is structural representation of the present utility model.
wherein: 1, workbench; 2, cage tool; 3, hold down assembly; 31, fixture; 32, depression bar; 4, extensible member; 5, air-vent; 6, locking piece; 7, root fixings; 8, end fixture; 9, opening.
Detailed description of the invention
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in Figure 1, a kind of fixing device for vena caudalis injection of mouse, comprises the fixture of workbench 1, cage tool 2, fixing Mus tail, and cage tool 2 lower edges offer opening 9, and in the time that it fastens mice, Mus tail can stretch out cage tool 2 from this opening 9.Fixture comprises offering along its length can allow the extensible member 4 of the groove that Mus tail puts into, Mus root of the tail portion is fixed on extensible member 4 by root fixings 7, root fixings 7 can be the setting tools such as primary and secondary adhesive tape or clip, extensible member 4 ends are provided with end fixture 8, end fixture 8 can be alligator clamp, on alligator clamp, for clamping on the clamping part of Mus root of the tail portion, cushion can be set, to prevent that crushing mouse makes its irritated struggle, end fixture 8 is fixed on Mus tail end on extensible member 4.
cage tool 2 is cup-shaped, and cage tool 2 is provided with multiple air-vents 5, and the diameter of cage tool 2 is slightly shorter than mice height (not comprising Mus tail), can limit well like this activity of mice.Cage tool 2 tops are fixed with the casting coping that quality is larger, when can preventing mice activity or acutely struggling, knock cage tool 2 over, while also making operator operate, without pressing cage tool 2, facilitate one hand to operate injection.On cage tool 2, be also provided with and hold down assembly 3, holding down assembly 3 vertically contacts on Mus tail, and should try one's best near Mus tail root position in 3 positions that are pressed on Mus tail that hold down assembly, thereby the position to be injected, middle part of Mus tail is exposed.Hold down assembly and 3 comprise fixture 31, fixture 31 is fixed on cage tool 2, fixture 31 offers through hole along the vertical direction, hold down assembly and 3 also comprise the depression bar 32 that can slide up and down in through hole, depression bar 32 is locked in fixture 31 by locking piece 6, locking piece can be screwed screw, screw can screw in through hole from the direction perpendicular to the through hole axle degree of depth, screw this screw as locking piece 6, depression bar 32 can be pushed against on the inner side perisporium of through hole and make the relative fixture 31 of depression bar 32 fixing.
