Description
Technical field
The utility model relates to it is a kind of in rat brain when micro-administration head and neck fixation device, belong to medical treatment
Test instrument equipment technical field.
Background technique
Carrying out fixed point micro-injection administration in experimental animal intracerebral specific region is a kind of directly effective experimental method, mesh
Before be widely used to the research fields such as neuro-physiology, Neuropharmacology.Such as in chronic ache research, it is often necessary to first
The operation of intracerebral pipe laying first is implemented to rat, then when rat is restored to close to physiological status, then to carry out intracerebral specific region slow
Slow trace drug injection, and then drug is observed to rat pain sensation behavioral implications.Entire drug micro-injection process does not require nothing more than greatly
Mouse is in waking state, but also to reduce rat as far as possible and move freely, and can just guarantee drug accurate injection to spy in this way
Surely brain area is studied.
Common method is that rat incidence is fixed using simple self-made tool at present, if towel wraps up rat, by
In not can be carried out effective fixation, it is poor to often result in rat compliance, eventually leads to drug and is unable to accurate injection to specific brain area, from
And influence experimental result accuracy；Sometimes it even will cause injection needle or brain pipe laying fall off continue experiment can not.
Utility model content
The purpose of the utility model is to overcome the deficiencies of the prior art, and it is simple to provide a kind of structure, easy to use
For in rat brain when micro-administration head and neck fixation device.
Technical solution provided by the utility model is:
The fixation device of head and neck when being used for micro-administration in rat brain of the utility model includes: that top has one to lack
Mouthful hex-shaped head fixed plate (1), neck fixed plate (5), connect respectively with head fixed plate (1) and neck fixed plate (5)
Facilitate bool (7)；Wherein:
Head fixed plate (1) center is equipped with an oblong openings (3), and oblong openings (3) lower part two sides are respectively provided with
One circular open (4), oblong openings (3) upper side are equipped with a pair of first velcro (2)；
The neck fixed plate (5) is rectangle, and upper and lower ends are respectively provided with a pair of second velcro (6).
The fixation device of head and neck when micro-administration in rat brain that is used for of the utility model uses market sale
Material makes according to a conventional method.
The utility model has the advantage that is with beneficial effect:
1, structure is simple, at low cost, easy to use, and dual effective fixation can be carried out to rat incidence and is influenced
Other positions of body activity, moreover it is possible to stablize and carry out micro-administration operation in specific brain area.
2, it also can be used in other similar animals.
Detailed description of the invention
Fig. 1 is the utility model unfolded state structural schematic diagram.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.When being used for micro-administration in rat brain of the present embodiment
The fixation device of head and neck is made according to a conventional method of the material of market sale.
As shown in Figure 1, the fixation device of head and neck when being used for micro-administration in rat brain of the utility model includes:
There is the hex-shaped head fixed plate 1 of a notch on top, neck fixed plate 5, connects respectively with head fixed plate 1 and neck fixed plate 5
What is connect facilitates bool 7；Wherein:
The center of head fixed plate 1 is equipped with an oblong openings 3, and 3 lower part two sides of oblong openings are respectively provided with a circle
Shape opening 4,3 upper side of oblong openings are equipped with a pair of first velcro 2；
The neck fixed plate 5 is rectangle, and upper and lower ends are respectively provided with a pair of second velcro 6.
The utility model use process:
When the bonding of the first velcro 2, head fixed plate 1 bends to the fixed rat of front end tapered stereoscopic structure jaggy
Head.Head fixed plate 1 is adjusted according to rat head size by the first velcro 2.
The center of head fixed plate 1 is equipped with an oblong openings 3, this region is used to carry out brain area micro-injection behaviour to rat
Make, area size is adjusted according to brain pipe.
A circular open 4 is respectively provided at left and right sides of oblong openings 3, this region is for the fixed rat head of finger.
Neck fixed plate 5 is rectangle, and upper and lower ends are respectively provided with a pair of second velcro 6, when the bonding of the second velcro 6
Annularly rat neck is placed on to fix.Neck fixed plate 5 prevents rat neck to be bent, to play the role of fixed neck.Neck
Fixed plate 5 is adjusted according to rat neck circumference by the second velcro 6.
Bool 7 is facilitated to be adjusted according to rat posture with what head fixed plate 1 and neck fixed plate 5 were connect respectively.
Practical application shows that the device is not only simple in structure, at low cost and very easy to use.
