Description
Technical field
The utility model belongs to mouse experiment equipment technical field, and in particular to a kind of mouse fixing.
Background technique
In mammalian laboratory animals, since mouse is small in size, feeding management is convenient, and easily controllable, Reproduction is fast, grinds
Study carefully most deep, has specific quality control standard, possessed a large amount of inbred strais, mutantion line and closed colony, therefore in various experiments
In research, dosage is maximum, and purposes is most.Mouse is the experiment of the subjects such as medical physiology, pharmacology, pathology, Pathological Physiology
Conventional animal.It include that intraperitoneal injection, intramuscular injection and tail vein are infused by the experimental implementation that mouse carries out in medical research
The injection such as penetrate to carry out the research of carry out physiology, toxicity, drug effect, when carrying out microbe research also usually to mouse progress bowel lavage
Experiment；There are also mouse peritoneal injecting anesthetics, docking blood sampling experiment etc. for common mouse experiment.It is different by implementing to mouse
Experiment is to realize different experiment purposes, medical value with higher.
Frequently with the method for manual fixed mouse when traditional mouse experiment, but due to will be with caution, neither in crawl
Can be rough, in case it is injured；It is steady and quasi- again, it is not so easy to be bitten by it, it is long in Mice Body to carry a variety of viruses, if small
Damaged by rats wound, will affect the health of experimenter, even results in breaking out for infectious disease, so mouse is fixed in experiment
It is that one of must solve the problems, such as.But existing mouse fixing, have limitation or purposes single or fixed
It is ineffective, be inconvenient to adjust or cannot be disposably in high volume fixed and handle mouse.Therefore it is badly in need of being directed to the prior art
The problem of, design a kind of new mouse fixing.
Chinese patent CN204364165U discloses a kind of tail vein injection experiment mice fixator, including a cylinder with
The spiral cover being connected at cartridge openings offers venthole on the barrel of cylinder, offers on spiral cover and mouse tail root diameter (RD)
The through hole that size matches, inner barrel are equipped with the limit plate for limiting mouse twisting, and limit plate is equipped with and tightens bolt；
Limit plate is equipped with two panels, is arc-shaped, is symmetricly set on cylinder, tightens bolt end head and be connected on limit plate, and wherein
Portion is screwed on cylinder.Compared with prior art, the utility model structure is simple, can using common centrifuge tube and bolt etc. into
Row assembly can be gathered materials on the spot with laboratory, not need extraneous expense and auxiliary material substantially.Although the fixator can be with needle
The spacing of two limit plates is adjusted to the mouse of different size figure, and is filled in appropriate cotton and fixed, but operation is more complex, and
Due to mouse difference in length, the length that tail portion is exposed is inconvenient to control；The device is also inconvenient to be injected intraperitoneally, four limbs note
It penetrates and is tested from anus bowel lavage；When testing for taking a blood sample, due to itself and not set Tail-heating device, being easy to produce blood coagulation causes
Blood sampling volume is less；And the device once can only also operate mouse always, be unable to batch processed, keep conventional efficient low.
Chinese patent CN202892142U discloses a kind of experiment rats and mice fastener component, including pedestal, U-shaped cylinder
With tail vein injection assistor, the pedestal head is set there are two the mouse fork pockets being parallel to each other, and mouse fork pockets outside is set
There are two the rat fork pockets that is parallel to each other, pedestal tail portion sets that there are two the tail vein injection assistor card slot being parallel to each other, institutes
The U-shaped cylinder stated is inserted in mouse fork pockets or rat fork pockets, and the tail vein injection assistor is inserted in tail vein injection
In assistor card slot.The large and small mouse of the utility model shares, and devises the tail vein injection auxiliary for meeting ergonomics
Device is applicable in the mouse of various figures, greatly simplifies muroid experiment, new hand also can be convenient and safely operate.But the device is only
It is injected suitable for tail portion and four limbs, it has not been convenient to it overturns fixator and mouse and abdomen injection is carried out to it, it is also inconvenient
Its inclination for carrying out special angle is caused to be inconvenient to carry out bowel lavage and collects excrement experiment；And the device once also can only be right
One mouse is operated, and is unable to batch processed, is substantially reduced conventional efficient.
Summary of the invention
In order to overcome the deficiencies of the prior art, one of the technical issues of the utility model aims to solve at least in the prior art,
A kind of mouse fixing is provided, suitable for the mouse of different building shape, facilitates adjustment mouse position and angle, it can be achieved that at batch
Reason improves conventional efficient.
The utility model is achieved through the following technical solutions: a kind of mouse fixing, including turntable, fixing seat and small
Rat holder；Turntable is fixed on workbench by shaft, and multiple fixing seats are arranged on turntable, and each fixing seat includes two pieces
It is parallel to each other and is each perpendicular to the fixed plate of turntable, the sliding slot of vertical direction is respectively provided in fixed plate, is arranged in each fixing seat
One fixed frame, the shaft of fixed frame two sides pass through sliding slot and are fixed in fixed plate by locking nut；Fixed frame
It is equipped with multiple fixators；The fixator includes the cylinder of both ends open, setting head taper fixing piece, middle part limit in cylinder
Position plate and tail portion piston；Middle part limit plate is fixed in the middle part of fixator by adjusting bolt, and middle part limit plate passes through cylinder head
Chute hole, head taper fixing piece and tail portion piston is equipped with tail portion to be arranged in chute hole by regulating part.
Using the utility model mouse fixing when, first mouse is put into mouse fixing device, passes through regulating part tune
Whole conical nose fixing piece and tail portion piston move in chute hole, adapt to the mouse of different length, by adjusting bolt or more
Mobile middle part limit plate is suitable for different fat or thin mouse, realizes good fixed effect.Originally it is applicable in the fixed dress of novel mouse
