Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figs 1-4, the dedicated fixator of minitype animal experiment MRI, including graduated scale 9 and by upper body support arc panel
1, the curved support plate that intermediate supports arc panel 2 and lower part of the body support arc panel 3 form, upper body support arc panel 1, intermediate supports arc
Shape plate 2 and lower part of the body support arc panel 3 are coaxially set.One end insertion upper body support arc panel 1 of intermediate supports arc panel 2 is inserted
Be slidably matched in slot and with slot, in the slot of the other end insertion lower part of the body support arc panel 3 of intermediate supports arc panel 2 and with insert
Slot is slidably matched.From one end far from intermediate supports arc panel 2 to close to intermediate supports arc panel 2 on upper body support arc panel 1
One end set gradually neck fixing belt 4, forelimb fixing belt 5 and upper fixing strap of waist 6, the lower part of the body supports arc panel 3 close to intermediate
Support one end of arc panel 2 that lower fixing strap of waist 7 is set, lower part of the body support arc panel 3 is set far from one end of intermediate supports arc panel 2
Postpone limb fixing belt 8.Intermediate supports arc panel 2 and upper body support arc can be adjusted according to the body length of minitype animal experiment
The distance between plate 1 and lower part of the body support arc panel 3, and then adjustable the distance between forelimb fixing belt 5 and hind leg fixing belt 8,
To adapt to the demand of minitype animal experiment.In the present embodiment, forelimb fixing belt 5 is two rows, a row close to neck fixing belt 4,
Forelimb lifts upwards when stretching to head, passes through the fixed forelimb of the row；For another row close to upper fixing strap of waist 6, forelimb stretches to waist
When, by the fixed forelimb of the row, therefore can be fixed according to the concrete condition of minitype animal experiment.
The side of curved support plate and parallel with curved support plate is arranged in graduated scale 9, and upper body support arc panel 1 is far from
Between support arc panel 2 one end side be arranged graduated scale support I 10, the lower part of the body support arc panel 3 far from intermediate supports arc panel 2
The side of one end graduated scale support II 11 is set, one end of graduated scale 9 is fixedly connected with graduated scale support I 10, graduated scale 9
The other end passes through graduated scale support II 11 and is slidably matched with graduated scale support II 11.The end of the other end of graduated scale 9 is arranged
The block 16 for preventing the other end of graduated scale 9 from slipping from graduated scale support II 11, intermediate supports arc panel 2 is with respect to upper body support
When arc panel 1 and mobile lower part of the body support arc panel 3, the other end of graduated scale 9 is also moved on graduated scale support II 11, due to this
The lateral dimension of block 16 is greater than the lateral dimension of the through-hole on graduated scale support II 11, in the end of the other end of graduated scale 9
When sliding into graduated scale support II 11, because of the barrier effect of block 16, the end of the other end of graduated scale 9 is avoided from graduated scale

Arc panel 1 is close to one end of intermediate supports arc panel 2 and lower part of the body support arc panel 3 close to one end of intermediate supports arc panel 2
It is that circular arc is excessive, connecting portion of the minitype animal experiment between contact upper body support arc panel 1 and intermediate supports arc panel 2
And intermediate supports arc panel 2 and the lower part of the body support arc panel 3 between connecting portion when, circular arc is excessively lined with the thin foam pad in the back side
It is more bonded with nuclear-magnetism coil inner surface, also substantially increases the comfort that minitype animal experiment is lain on curved support plate.
Neck fixing belt 4, forelimb fixing belt 5, upper fixing strap of waist 6, lower fixing strap of waist 7 and hind leg fixing belt 8 one
On end be arranged felt bonding layer 14, neck fixing belt 4, forelimb fixing belt 5, upper fixing strap of waist 6, lower fixing strap of waist 7 and after
Felt layers 15 are set on the other end of limb fixing belt 8, as shown in figure 3, in use, only need to be by the corresponding site of minitype animal experiment
It is placed on corresponding part, being overlapped in felt layers 15 by the felt bonding layer 14 at this can be by the corresponding of minitype animal experiment
Position is fixed, and when release, only felt bonding layer 14 need to be torn from felt layers 15.In the present embodiment, upper body support arc
Two through-holes, the position point of forelimb fixing belt 5 corresponding with upper row and lower row are set on plate 1 with 4 corresponding position of neck fixing belt
Corresponding two through-holes are not set, two through-holes are set with upper 6 corresponding position of fixing strap of waist；On lower part of the body support arc panel 3
Two through-holes are set with lower 7 corresponding position of fixing strap of waist, two through-holes are set with 8 corresponding position of hind leg fixing belt.Neck is solid
The both ends (i.e. 15 both ends of felt bonding layer 14 and felt layers) of band 4, forelimb fixing belt 5 and upper fixing strap of waist 6 are determined from upper body
The corresponding through-hole in bottom of support arc panel 1 is pierced by upwards, and the both ends of lower fixing strap of waist 7 and hind leg fixing belt 8 are from the lower part of the body
The corresponding through-hole in bottom of support arc panel 3 is pierced by upwards, and the middle part of fixing belt is located at the lower section of curved support plate, will not influence
Minitype animal experiment is fixed on curved support plate.
When fixator dedicated using minitype animal experiment MRI, minitype animal experiment is placed on curved support plate, is led to
It crosses neck fixing belt 4 to fix its neck, its forelimb is fixed to (forelimb fixing belt 5 is two rows, can root by forelimb fixing belt 5
Selection is carried out using that row's forelimb fixing belt 5 according to the forelimb or forelimb fixed form that are directed to different experimental animals), by upper
Fixing strap of waist 6 will be fixed waist thereon, and intermediate supports arc panel 2 can be adjusted according to the body length of minitype animal experiment and is existed
Upper body support arc panel 1 and lower part of the body support the distance between arc panel 3, can be adjusted forelimb fixing belt 5 and hind leg fixing belt 8 it
Between distance then its lower waist is fixed by lower fixing strap of waist 7 again, is passed through to adapt to the demand of minitype animal experiment
Hind leg fixing belt 8 fixes its hind leg.It, can be according to minitype animal experiment for upper fixing strap of waist 6 and lower fixing strap of waist 7
Figure length selects, if figure is shorter, may be selected in upper fixing strap of waist 6 and lower fixing strap of waist 7 one, if body
Type is long, can fixing strap of waist 6 and lower fixing strap of waist 7 this two in simultaneous selection.During fixation, it can refer to and set
It sets minitype animal experiment in the graduated scale 9 of curved support plate side and the position line 12 that is arranged on upper body support arc panel 1
Target region is accurately positioned at nuclear-magnetism coil center, is conducive to minitype animal experiment and carries out nuclear magnetic resonance image check.The small-sized reality
Test the dedicated fixator of animal MRI can standard minitype animal experiment is fixed, and can be applicable in various minitype animal experiments relatively, can
It reuses.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
