Description
Technical field
Fixed the utility model relates to a kind of laboratory mice and intravenous injection device more particularly to a kind of mouse fix and
Visualize tail vein injection device.
Background technique
Mouse tail vein injection is a kind of common experimental technique, especially new drug development, screening, acute toxicity test with
And it is widely used in further drug efficacy study.But since mouse natural disposition is timid, in addition its tail vein is tiny and tube wall is very thin,
Great difficulty is brought to fixed and tail vein injection, influences the mood and confidence of operator.This requires operators frequently to practice
Technology, while needing enough patience；Nevertheless, the success rate of mouse tail vein injection is not still high.According to forefathers'
Cognition of the experience in conjunction with us in practical operation, has following reason to influence the success rate of mouse tail vein injection.First, mouse
Fixation it is whether secured；Second, tail vein appear and whether filling degree is satisfied with；Third, the selection of syringe and inserting needle
Angle is different.
Currently, for mouse tail vein injection device, the fastness of the main fixation for considering mouse, and have not been able to combine me
End of line intravenous injection operating process in Technology Difficulties, as mouse tail vein appear and filling degree control, be adjusted flexibly
Needle angle etc..
Chinese utility model patent CN201775695 U describes a kind of extremely easy mouse fixing device, with 50ml
Centrifuge tube is provided with aperture as fixator, centrifuge tube bottle cap and centrifugation tube body, is respectively used to mouse tail vein and places and lead to
Gas, but defect is not limited further mouse, during operation, mouse is frightened or pain stimulation, meeting
It struggles, turns due, influences tail vein injection.204364165 U of Chinese patent CN on its basis, is being centrifuged tube two sides
Equipped with limit plate, certain limitation is carried out to mouse carry out activity, but because mouse size height is different, space in fixing pipe
It is not adjustable, fixed effect is still unsatisfied with.The recreation room of Chinese patent CN102451046 device includes that movable part and first are narrow
Seam, movable part can adjust fixed chamber inner length by nut and across the screw rod of the first slit, this can be according to mouse
Height adjusts fixed indoor space, makes mouse fixation.Chinese invention patent CN104840268 A is on this basis, right
It is improved in technique, which mainly includes fixed cylinder and magnet fixed bin, and fixed cylinder includes slit, ring segment and cylinder
Door can adjust the length of fixed cylinder according to the height of mouse, and ring segment can further limit mouse, and magnet fixed bin can
To be adsorbed in iron content plane, convenient for placing, the fixed problem of mouse is substantially solved, but have ignored tail vein injection process
In Technology Difficulties.204446167 U disclosed device of Chinese patent CN 203749638 U and Chinese patent CN all contains mouse
The fixture of tail plays certain fixed function to mousetail, but the two devices are on mouse is fixed and tail vein appears
There are major defects.Therefore, in order to solve fixation and the problems such as the appearing of tail vein of mouse simultaneously, we design a kind of new
Type utility unit, the device in addition to that fine can must solve mouse fixation problem, biggest advantage are visualized by increasing, and make tail
Vein preferably appears, while can adjust the angle of rat-tail fixed plate, convenient for the adjustment of needle angle.
Summary of the invention
The purpose of the utility model is to provide a kind of new to fix and visualize tail vein injection device for mouse, can be with
It solves the problem of that we fix in especially tail vein injection operating process in mouse to encounter.
The technical solution that the utility model is taken are as follows:
Tail vein injection device, including objective table, fixed device and visualization injection are fixed and visualized to a kind of mouse
Device.
The objective table includes pedestal and battery slot.
The fixed device is set on the objective table, including transparent fixation cylinder, equipped with the leakage of ventilation hole
The infundibulate piston can be pushed and pulled in fixed cylinder using piston handle, be limited by bucket shape piston, piston handle and position limiting structure
Structure limits piston handle push-pull range.The infundibulate piston is designed according to the physiological curve of mouse skull, and inner face is leakage
It is bucket-shaped, it is frosting with tube wall contact position, and be provided with ventilation hole, the head of mouse can be efficiently controlled, but not shadow
The eupnea of mouse is rung, while the forelimb of mouse can also be allowed to put comfortably.Lift mousetail, it is with " rear pull type " that mouse is fast
Quick-mounting pushes piston handle that mouse is fixed into infundibulate piston, and push-in depth cannot be stirred freely with mouse, respiratory rhythm
Normally it is advisable.
The visualization injection device is set to the objective table tail end, including injection plate, injection plate center transparent cell,
Light emitting device, rat-tail fixing clamp and end fixing sleeve.The rat-tail fixing clamp is located at rat-tail root, in addition to being mainly used for rat-tail root
Outside the fixation in portion, additionally it is possible to play certain contention effect, make mouse tail vein full, full degree can be according to pressure tune
Control.End fixing sleeve is capable of fixing the tail end of mouse.After opening light emitting device mouse tail vein can be recognized by transparent cell
It is out of shape, reach effect of visualization.
The present invention can also be using following further technical measures:
The position limiting structure is arc-shaped limit plate, is fixed on fixed cylinder by traveling nut.
The fixed cylinder is transparent plastics material, and inner surface is frosting, it can be observed that after fixed mouse symptom
And sign.
The injection plate is transparent materials.
The light emitting device includes switch and the LED light below transparent cell.
During tail vein injection, the problem of also frequently encountering needle angle, because mouse vein is tiny, tube wall is very
Weakness, if needle angle is excessive, it is easy to just poke blood vessel, into subcutaneous, cause injection to fail, if the angle mistake of inserting needle
Small, operator's operating difficulties increases.In order to solve this problem, we devise the conjunction of connection visualization injection device and pedestal
Page structure, can freely adjust the angle of funcition table for injecting, and operator can look for one to be suitble to relaxing for oneself inserting needle according to the actual situation
Suitable angle, to improve the success rate of tail vein injection.
Include: using beneficial effect is generated after above-mentioned technical solution
1, while solving the problems, such as that mouse is fixed, a kind of visualization tail vein injection device is provided；
2, visualization tail vein injection device can recognize that mouse tail vein is walked by transparent cell after opening light emitting device
Shape reaches effect of visualization；
3, rat-tail fixing clamp keeps mouse tail vein full, full degree can be according to pressure tune by compressing rat-tail root
Control；
4, by the hinge structure of connection visualization injection device and pedestal, the angle of funcition table for injecting can be freely adjusted, into
And improve the success rate of tail vein injection.
