Description
Technical field
The utility model is related to animal medicine experiment equipment technical field, more particularly to a kind of noninvasive self-adjustable mouse gavage
Pin.
Background technology
With development in science and technology and the fusion of multi-door science, zoopery turn into medicine and pharmacology, food security science and its
The basic skills of his related science experimental study.In process of the test, according to experimental study purpose, experimental animal species and medicine
Formulation, the difference of dosage, need to implement different medications to experimental animal, wherein oral gavage method be it is a kind of it is important to
Medicine approach.
The gastric perfusion needle of the experimental animal used at present is mainly made up of metal material, and essential structure is the metal needle of falling droplet-shaped
Head, metal catheter and the metal base being connected with syringe.Existing patent is by the experimental clinic of metal catheter
It is required that certain radian is had been designed to, to adapt to the alimentary canal structure of experimental animal.As Chinese patent CN203634328U is announced
A kind of experimental mouse irrigation stomach device, including syringe, gastric perfusion needle is plugged with front end of the syringe needle, and the gastric perfusion needle is bendable gavage
Pin, the angle of gastric perfusion needle bending is 120-150 degree, insertion depth indicator graduation lines is provided with the outer wall of gastric perfusion needle, in gastric perfusion needle
End provided with protection bulb, protection bulb on be provided with multiple drug row holes connected with gastric perfusion needle medicine-pouring hole.
The gastric perfusion needle of above-mentioned prior art sets the bending angle of 120-150 degree, although structure and gastral structure are more
Matching, but because metal material is really up to the mark, during animal stomach and administration is inserted, it is possible to causing experimental animal strong
Discomfort, and the coat of the stomach of injury experiment animal.Multiple drug row holes connected with gastric perfusion needle medicine-pouring hole are set, and processing technology is more multiple
It is miscellaneous, also there is certain limitation to the quantity in aperture.
The content of the invention
The purpose of this utility model is a kind of noninvasive self-adjustable mouse gastric perfusion needle of offer, can improve metal material gastric perfusion needle
The situation for causing experiment body uncomfortable, causes inaccurate, the uncontrollable problem of administration while can effectively solve coat of the stomach and block liquid outlet.
To achieve the above object, above-mentioned technique effect is reached, the utility model solves above-mentioned ask by the following technical programs
Topic：
A kind of noninvasive self-adjustable mouse gastric perfusion needle, including needle stand, the needle tubing being connected with needle stand, the pin positioned at needle tubing front end
Head, the body of the needle tubing is bellows-like structure.The gastric perfusion needle of metal material is harder, is inserting the mistake of animal stomach and administration
Cheng Zhong, can cause inadaptable, the coat of the stomach of injury experiment animal of experimental animal strongly.The body of bellows has preferably curved
Bent deformation nature, body can be according to animal oral cavity and the shape adjust automatically angle of bend of stomach, and slips into stomach along esophagus,
Reduce damage of the time conjunction inserted to coat of the stomach；The body of shape can be automatically adjusted simultaneously, can be during administration preferably
Adapt to the change of internal animal organ, it is to avoid the caused coat of the stomach damage during struggling of experiment body.
As a kind of above-mentioned improvement of noninvasive self-adjustable mouse gastric perfusion needle of the utility model, the syringe needle is ellipsoid mesh
Structure, afterbody is connected with needle tubing.Ellipsoid needle tip has large surface area, it is to avoid stab coat of the stomach；The syringe needle energy of mesh
Increase administration hole number, is prevented effectively from because the situation that administration hole plug can not be administered occurs.
As a kind of above-mentioned improvement of noninvasive self-adjustable mouse gastric perfusion needle of the utility model, wrap up removable on the outside of the needle tubing
The protective case unloaded.The body of bellows-like structure has fabulous bending property, can be in body when body needs appropriate rigidity
Outer wrapping different-thickness and the protective case of material increase the purpose of body rigidity to reach.
As a kind of above-mentioned improvement of noninvasive self-adjustable mouse gastric perfusion needle of the utility model, the needle tubing and syringe needle are using tool
Flexible latex or PVC material.Latex or PVC material cost is low, plasticity is good, is used frequently as disposable experiment with material；
And for latex or PVC material are compared with metal, with preferable deformability, the damage to coat of the stomach is smaller.
The beneficial effects of the utility model are：
1st, the utility model uses the bellows body with preferable bending property, and body can be according to animal oral cavity and stomach
The shape adjust automatically angle of bend in portion, and stomach is slipped into along esophagus, it is easy to insert.
2nd, the bellows body with preferable bending property, preferably can adapt to internal animal during administration
Organ changes, and reduces coat of the stomach damage caused by experiment body struggle.
3rd, ellipsoid needle tip has large surface area, it is to avoid stab coat of the stomach；The syringe needle of mesh can increase dosing holes
Quantity, can be prevented effectively from because of the situation that administration hole plug can not be administered.
4th, in body outer wrapping detachable protective set, body rigidity can be changed as needed, to reach increase
The purpose of body intensity.
The utility model can preferably improve metal material gastric perfusion needle and cause the uncomfortable situation of experiment body, while can effectively solve
Coat of the stomach, which blocks liquid outlet, causes inaccurate, the uncontrollable problem of administration.
Brief description of the drawings
Fig. 1 is a kind of noninvasive self-adjustable mouse gastric perfusion needle schematic diagram.
