There are both sides corresponding with the circular arc gap plate on the slide unit being engaged with the chute, the telescopic mast respectively to carry scale,
Side scale numerical value is set from big to small, and opposite side scale numerical value is set from small to large, is all provided with described two circular arc gap plates
There are two pointers, described two pointers are corresponding with described two scales respectively.
It is preferred that, the chute is arranged on injection tube inwall and between two circular arc gap plates.
It is preferred that, the chute is two, and the slide unit is two.
It is preferred that, with being recessed scale face at scale on the telescopic mast, the scale face and injection tube inwall it
Between have gap.
Improvement of the present utility model mainly has：In terms of syringe：1st, syringe woven hose fixes road with telescopic mast；2nd, note
Emitter telescopic mast carries tongue corresponding with fixed road；3rd, scale is carried on syringe telescopic mast；4th, syringe circular arc gap plate
It is respectively provided with two pointers.
The beneficial effects of the utility model：Compared with prior art, irrigation stomach device used in the large and small mouse of experiment of the present utility model
Syringe, as a result of a kind of utility model rat oral gavage syringe, telescopic mast is attached to using by graduated scale, Gu
Determine limitation telescopic mast motion, the accurate indicating graduation of indicator effectively prevent because long-time abrasion causes scale unintelligible,
Scale is overlapped with decoction, the problems such as given low is inaccurate, greatly improves conventional efficient.
Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description
In become obvious, or by it is of the present utility model practice recognize.

Embodiment
Embodiment of the present utility model is described below in detail, wherein from beginning to end same or similar label represent it is identical or
Similar element or the element with same or like function.The embodiments described below with reference to the accompanying drawings are exemplary,
It is intended to be used to explain the utility model, and it is not intended that to limitation of the present utility model.
Fig. 1-4 is the structural representation of the experimental mouse gavage syringe of the utility model embodiment.It include injection tube 1,
Gastric perfusion needle 2, circular arc gap plate 3, telescopic mast 4, chute 5, slide unit 6, scale 7 and pointer 8.
The front end of injection tube 1 is connected with gastric perfusion needle 2, and rear end is provided with two relative circular arc gap plates 3.Set in injection tube 1
Telescopic mast 4 is equipped with, the inwall of injection tube 1 is provided with two chutes 5, and two chutes 5 are arranged on the inwall of injection tube 1 and positioned at two
Between circular arc gap plate 3.Telescopic mast 4 is provided with two slide units 6 being engaged with chute 5, and slide unit 6 can be kept in chute 5
Under sealing slidably.On telescopic mast 4 both sides corresponding with circular arc gap plate 3 respectively carry scale 7, the numerical value of side scale 7 from
Small setting is arrived greatly, and the numerical value of opposite side scale 7 is set from small to large, and two pointers 8, two are equipped with two circular arc gap plates 3
Pointer 8 is corresponding with two scales 7 respectively.The scale face that is recessed at scale 7, scale face and injection tube 1 are carried on telescopic mast 4
There is gap between inwall.
As a specific example of the present embodiment, the telescopic mast 4 is provided with several horizontal grooves (not shown),
Groove is arranged at the graduation mark of scale 7, such as sets groove at the graduation mark of 10,20,30,40,50 units respectively.The groove
Interior pluggable locating rod, and locating rod protrusion scale facial plane, when telescopic mast 4 is moved forward and backward in injection tube 1, work as locating rod
When contacting circular arc gap plate 3, circular arc gap plate 3, which can block locating rod, prevents retracting cylinder from continuing to press on.When needing accurate handle
Given low is held, locating rod can be inserted in groove accordingly after suction decoction, such as imbibition to maximum capacity 50ml, such as
Gavage 20ml is needed, but locating rod is inserted at corresponding scale 30ml, circular arc gap plate 3 is directly pushed to and blocks locating rod.
Make the pharmaceutical quantities of each gavage identical when so may be such that and repeatedly pushing medicament.
The course of work：One hand-held injection tube 1, a hand-held telescopic mast 4 is corresponding with chute 5 by telescopic mast 4, and telescopic mast 4 is slided
Enter injection tube 1.Telescopic mast 4, the descending side of the high scale 7 of eye gaze telescopic mast 4, until required are pulled when drawing decoction
Decoction scale 7 is completely superposed with indicator, is taken target decoction to draw and is finished.During liquid medicine injection, carved on eye gaze telescopic mast 4
7 ascending sides are spent, until institute's liquid medicine injection scale 7 is completely superposed with indicator, injecting liquid drug is finished.It is complete above
Range decoction is drawn and injecting method, if needing only to part decoction in range, uses any side telescopic mast 4.
New rat oral gavage syringe woven hose fixes road with telescopic mast 4, and limitation telescopic mast 4 can only be on chute 5 be interior
Lower slider.Scale 7 is located on the telescopic mast 4 inside syringe, can persistently use without the scale 7 that weares and teares.Distinguish the both sides of telescopic mast 4
Symmetrical with slide unit 6 corresponding with fixed road, and with scale 7, scale 7 is respectively from big to small and from small to large, to make
All it is to read from small to large when must draw and inject.In addition, syringe circular arc gap plate 3 is respectively provided with two pointers 8, refer not only to
Show accurate, and observation is convenient, extracts, injection is quick, no matter what color decoction drawn, does not affect operator's observation and essence
Really injection, it is ensured that draws and inject is accurate.The utility model improves syringe and the wear problem of scale 7 is used for a long time, and subtracts
The use of few disposable syringe, is conducive to Save Resource Protect Environment.Or when decoction is dark color, scale 7 is easily blanked, and is led
Cause does not see scale 7, and dosage is not accurate when causing injection, causes unnecessary experimental error.Pointer 8 indicates accurately, watcher
Just, it is easy to fast injection, is conducive to improving operating efficiency.This utility model syringe is very suitable for the gavage work of big mouse
Make, it is ensured that accurate dosage, it is ensured that experiment is accurate quickly to be carried out.Other the utility model is simple in construction, easily manufactured, can push away
Extensively use.
While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that：
These embodiments can be carried out with a variety of changes, modification in the case where not departing from principle of the present utility model and objective, replaced
And modification, scope of the present utility model limits by claim and its equivalent.
