Abstract
The invention discloses a non-invasive self-adjusting lavage needle for a mouse. The needle comprises a needle base, a needle tube connected with the needle base, and a needle head located at the front end of the needle tube. A tube body of the needle tube is of a corrugated pipe structure. The needle head is of an oval mesh structure, and the tail of the needle head is communicated with the needle tube. The outer side of the needle tube is wrapped in a detachable protective sleeve. The bending angle of the tube body of the corrugated tube can be automatically adjusted according to the shapes of the oral cavity and the stomach of an animal, implantation is convenient, the tube body can better adapt to the change of organs in the animal, and stomach wall damage caused by struggling of an experimental body is reduced. The front end of the oval mesh needle head has larger superficial area, and the situation that drug administration cannot be carried due to blockage of a drug administration hole can be effectively avoided. The tube body is wrapped in the detachable protective sleeve, and the rigidity of the tube body can be changed. The situation that the experimental body is uncomfortable due to a lavage needle made of metal can be well relieved, and meanwhile the problems that drug administration is not accurate and not controllable due to the fact that a liquid outlet is blocked by the stomach wall can be effectively solved.
Description
Technical field
The present invention relates to animal medicine experiment equipment technical field, more particularly to a kind of noninvasive self-adjustable mouse gastric perfusion needle.
Background technology
With development in science and technology and the fusion of multi-door science, zoopery become 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, animal used as test 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 animal used as test for using 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
Requirement has been designed to certain radian, to adapt to the alimentary canal structure of animal used as test.As Chinese patent CN203634328U is announced
A kind of experimental mouse irrigation stomach device, including syringe, in front end of the syringe needle gastric perfusion needle is plugged with, 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 be 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 arranges the bending angle of 120-150 degree, although structure is with gastral structure more
Matching, but due to metal material it is really up to the mark, insert animal stomach and administration during, it is possible to causing animal used as test 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 restriction to the quantity in aperture.
The content of the invention
It is an object of the invention to provide a kind of noninvasive self-adjustable mouse gastric perfusion needle, can improve metal material gastric perfusion needle and cause
The uncomfortable situation of experiment body, while energy effectively solving coat of the stomach blocking liquid outlet causes inaccurate, the uncontrollable problem of administration.
For achieving the above object, above-mentioned technique effect is reached, the present invention solves the above problems by the following technical programs：
A kind of noninvasive self-adjustable mouse gastric perfusion needle, including needle stand, the needle tubing being connected with needle stand, positioned at the pin of needle tubing front end
Head, the body of the needle tubing is bellows-like structure.The gastric perfusion needle of metal material is harder, in the mistake for inserting animal stomach and administration
Cheng Zhong, can cause inadaptable, the coat of the stomach of injury experiment animal that animal used as test is strong.The body of bellows has preferably curved
Bent deformation nature, body according to animal oral cavity and the shape adjust automatically angle of bend of stomach, and can slip into stomach along esophagus,
The time that reduction is inserted closes the damage 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 caused coat of the stomach is damaged during experiment body is struggled.
Used as a kind of above-mentioned improvement of noninvasive self-adjustable mouse gastric perfusion needle of the present invention, the syringe needle is ellipsoid mesh knot
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 of mesh can increase
Plus administration hole number, it is prevented effectively from because the situation generation that hole plug cannot be administered is administered.
Used as a kind of above-mentioned improvement of noninvasive self-adjustable mouse gastric perfusion needle of the present invention, needle tubing outside parcel is dismountable
Protective case.The body of bellows-like structure has fabulous bending property, when body needs appropriate rigidity, can be in body outsourcing
Wrap up in the protective case of different-thickness and material to reach the purpose for increasing body rigidity.
Used as a kind of above-mentioned improvement of noninvasive self-adjustable mouse gastric perfusion needle of the present invention, the needle tubing and syringe needle are adopted and have bullet
The latex or PVC material of property.Latex or PVC material low cost, plasticity are good, are used with material frequently as disposable experiment；And breast
For glue or PVC material are compared with metal, with preferable deformability, the damage to coat of the stomach is less.
The invention has the beneficial effects as follows：
1st, using the bellows body with preferable bending property, body can be according to animal oral cavity and stomach for the present invention
Shape adjust automatically angle of bend, 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 the coat of the stomach damage that experiment body struggle causes.
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 the situation that hole plug cannot be administered is 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 present invention can preferably improve metal material gastric perfusion needle and cause the uncomfortable situation of experiment body, while can effectively solving coat of the stomach
Blocking liquid outlet causes inaccurate, the uncontrollable problem of administration.
