Description
Technical field
The utility model is related to fixing device, and in particular to a kind of rat fixator.
Background technology
The teaching and scientific research of functional subjects correlation are one of doctor, the important process content of pharmacy relevant speciality.Inspire and train
Student's Creative Thinking is supported, updates and develops the developing direction that functional subjects experimental method is following discipline construction.At present, undergraduate course
Raw experimental teaching form is that experimental procedure is improved to be easy to student to operate mostly, this allow for the important experiment content in part because
Instrument lacks or does not apply to and have to simplify or give up, and does not reach the requirement of teaching.Therefore, existing instrument is improved and
Innovation, can not only training student divergent thinking, raising starts and operational capacity, and can create higher social and economy
Value.
In teaching experiment, often rat is regard as sheet, two's physiology, Pathological Physiology, pharmacological experimental subjects.
Experiment is strong with rat invasive, and disposition is more violent, is easily stung to fury, is difficult to fix, and rat seizure fixation is conventional basic
Laboratory facilities.Tail vein injection, intraperitoneal injection, acupuncture etc. are again conventional experimental implementations.On the one hand, the science for being related to rat is ground
Study carefully, it is desirable to high to the fineness of operation, the accuracy at administration and Focal drug-block position is high, it is desirable to dosage to Conscious Rat and
The stability of operation technique is high；On the other hand, experiment of the rat under narcosis, anaesthetic dosage is difficult to control to, animal dead
Rate is high, influences the accuracy of experiment, and some experiments such as anti-inflammatory experiment and chlorpromazine are to basic metabolism and the influence of body temperature
Also require that and use Conscious Rat.Due to student first contacts experimental animal, all be present some problems in psychology and technical elements, test
During contact nearer with rat, students' skill is not familiar, operate it is unskilled, both add potential safety hazard, teaching had a strong impact on again
Quality.In anti-inflammatory realization most of students' unions foot bottom egg white injection precision is poor caused by rat fixes difficulty, toes thickness or
Volume determination error rate is big and causes the failure of an experiment.How on the premise of safe and feasible, the items for being related to rat are smoothly completed
Experiment, this is the problem that must be faced in experimentation.And presently commercially available rat fixator, more based on tubular, space envelope
Close, function is single, it is big to rat nocuity, do not meet the optimization principles of " 3R " (reduce, substitute, optimizing) and the human relations of experimental animal
Neo-Confucianism is required.Existing tubular fixator, rat ear is inserted to be fixed when it fixes rat head by iron bolt more, by
Nocuity has been carried out to rat to fix, so easily producing pessimal stimulation to rat, and then be easily caused rat in experiment in it
During occur head revolution sting people's situation, in addition, this nocuity fixed form is easily caused the death of rat.Existing rat
Rat foot is fixed more by way of making the foot of rat and passing through preformed hole for fixator, due to other no auxiliary
Fixation, causes rat foot easily to be shaken off from hole.In addition, present rat fixator function is single, list can only be carried out more
One property is tested, and generally requires to purchase polytype fixator when carrying out multinomial experiment, so as to add experimental cost.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of rat fixator, the fixator is fixed
Performance is good, can prevent rat from shaking off in experimentation, and can be effectively prevented from the situation that people is stung in rat revolution in experimentation
Occur, the fixator can mitigate the pessimal stimulation to rat body, it is fixed to rat injures small, can be in the shape that need not be anaesthetized
Related experiment is can be carried out under state, so as to reduce the higher death rate caused by Anesthetic factor, experiment can be improved
Success rate and reliability, in addition, the fixator is vdiverse in function, can be convenient for kinds of experiments application, its low manufacture cost, general
Property it is strong, be convenient for promoting.
To achieve these goals, the utility model provides a kind of rat fixator, including fixed bottom plate and fixed net, institute
The middle part for stating fixed net is curvedly bent to away from fixed bottom plate direction, and the rear end of fixed net is along with being fixedly installed on fixed bottom
The hinge ring of plate upper surface posterior edges is hinged, the quantity at least two of the hinge ring, the fixed plate upper surface front side edge
Edge, which is fixed with least two, is used for the hook that twisting fixes net front end edge, and fixed plate upper surface right side central is fixedly installed
The barrier plate that fore-and-aft direction stretches, fixed plate upper surface left side central portion is abreast fixedly installed two steady stern posts, and two steady
Stern post left part is provided with two elastic webbings.
In the technical scheme, coordinate fixed rat with fixed bottom plate by making to fix net, it is ensured that rats breathing
It is smooth, and then it is avoided that the situation of asphyxia occurs.It is real that fixed online mesh can be convenient for acupuncture in rat up to after fixing
Test.The cooperation of barrier plate and two steady stern posts can hinder rat play forward or backward after fixation, so as to add fixation
Stability；In addition, two steady stern posts can fix the buttocks of rat, consequently facilitating tail vein injection and taking blood.Two bullets
Property band setting, can be in order to the fixation of rat heel portion, so as to be convenient for rat paw edema experiment, the heel of rat
Not only scorching medicine can be caused in order to disposable success albumen injection after portion's fixation, meanwhile, it can also be easy to static by slide measure
Measurement.The fixator can stably fix rat, can not only prevent rat from shaking off in experimentation, and can effectively keep away
Exempt from the situation generation that people is stung in rat revolution in experimentation, the fixator can mitigate the pessimal stimulation to rat body, and it is to big
Mouse, which is fixed, injures small, related experiment can be can be carried out in the state of it need not anaesthetize, so as to reduce because of Anesthetic factor institute
The caused higher death rate, can improve the success rate and reliability of experiment, in addition, the fixator is vdiverse in function, can be easy into
Row kinds of experiments application, its low manufacture cost, highly versatile, be convenient for promote.
Further, for the ease of the rat after fixation is injected intraperitoneally, the position kept left in the middle part of the fixed bottom plate
The intraperitoneal injection hole of its thickness direction is provided through, intraperitoneal injection hole position is in the right side of steady stern post.
Further, in order that the fixator can be adapted to various sizes of rat, to increase the versatility of the fixator, also wrap
The regulation stud being vertically fixedly installed on fixed bottom plate is included, the regulation stud is located in the middle part of fixed bottom plate and close to fixed
Net and be equipped with nut in the position on rear end edge, regulation stud.
Further, in order to improve injection precision, the intraperitoneal injection hole is obliquely set from left to right from top to bottom, and it inclines
Rake angle is 45 degree.
Further, in order to increase the stationarity of fixed bottom plate, meanwhile, also for can more easily take the fixator, institute
