Description
Technical field
This utility model relates to a kind of fixture for animal head drug injection, belongs to behavior electrophysiologic study instrument and equipment field.
Background technology
In neuroscience and psychological study field, often need to carry out sobering animal behavior electricity physiology and the genetic research of light (in body experiment), as when the rat experiment, wherein very important a kind of research is that rat is fixed, and then head is carried out to drug slow injection, observe the impact on learning and memory in rats behavior, this just requires animal should regain consciousness (being convenient to consummatory behavior task), reduce again the freely movable of animal, the medicine that can guarantee like this arrives injection site accurately, and this head drug injection fixture is for fixedly the stability of rat health and head and the requirement of persistent period are very high, therefore can realize under animal waking state mouse head is carried out to drug injection, determine often the key of experiment success or failure.
Also there is no at present the special head drug injection fixture for Conscious Rat, the method that used is used is to make rat be completely fixed (with the activity of muscle relaxant paralysis animal) or in beaker, carry out the experiment of Electrophysiology, front a kind of method animal is used anesthetis additional gas cannula and artificial respiration to carry out so-called " clear-headed braking " to animal, though this can realize the stable braking of animal waking state, but large to animal injury, and the impact because of tracheotomy and intubate, animal is difficult to Long-term breeding, also be inconvenient to be used for chronic and dynamic experiment observation, can only be for acute experiment, and anaesthetic may affect the medicine that we test use, and then reduce the curative effect of medicine or increase the weight of the mutual toxicity between medicine.Because the compliance of rat is poor, activity often causes the position of drug injection inaccurate, even causes the disengaging of syringe, and experiment cannot normally be carried out.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of fixture for animal head drug injection is provided, and it is simple in structure, very convenient when animal head carries out drug injection.
Fixture for animal head drug injection described in the utility model, comprises workbench, it is characterized in that: head fixed mechanism, body part fixed mechanism and afterbody fixed mechanism are installed on workbench from left to right successively; Head fixed mechanism comprises the head standing screw of adjustable plate and two longitudinal arrangements, and adjustable plate is movably fixed on workbench, and head standing screw is arranged on adjustable plate by nut, offers the chute longitudinally regulating for head standing screw on adjustable plate; Body part fixed mechanism comprises two regulating blocks that are laterally arranged in parallel, between two regulating blocks, be provided with two fixing heads that are arranged in parallel, on each regulating block longitudinal direction, be independently coated with body portion standing screw, every body portion standing screw is all fixed with the sidewall of close fixing head, and is movably fixed on regulating block by nut.
The afterbody standing screw that further the preferred described afterbody fixed mechanism of this utility model is two longitudinal arrangements offers the chute that afterbody standing screw horizontally slips on workbench.
Further, described adjustable plate is movable fixing by bolt and workbench, offers the chute horizontally slipping for bolt on workbench.
Further, in order to facilitate animal to fix, the cross section of preferred described fixing head is camber structure.
Compared with prior art, the utlity model has following beneficial effect:
It is simple that fixture for animal head drug injection described in the utility model has making, cost is low, easy to use, when carrying out animal head drug injection, stability is high, is highly suitable for chronic experiment and the audition Related Experimental Study of brain research.This utility model has solved the problem of sobering animal head drug injection, has improved work efficiency, has promoted carrying out of association area research work.
