Abstract
The utility model relates to a be used for dabbling device of animal, including intubate and the pipe that communicates each other, the outer wall of intubate is equipped with the scale, but the extending structure who forms is cup jointed by two at least pipe joint materials to the intubate. The utility model discloses a but the sleeve pipe is extending structure, is applicable to that the equidimension animal is not cardiac pours into, is equipped with the scale at the outer wall of intubate, can accurately show that the intubate inserts the length of heart and artery, the front end of intubate is equipped with the spheroid for intubate location is convenient and can avoid heart and artery to receive the damage, so the utility model has the advantages of application scope is wide, convenient to use, safety, high efficiency.
Description
Technical field
This utility model relates to the apparatus introducing solid, liquid or gaseous medication or other materials in animal body, is specifically related to a kind of device for animal perfusion.
Background technology
In biomedicine experiment, draw materials to carry out further experiment detection to be one of experimental technique commonly used the most to various laboratory animal perfusion.The various success or failure organizing the fine or not direct relation of fixed effect further experiment after perfusion.When pouring into various animal at present, all need, by left ventricle, intubate is inserted aorta, first saline injection makes the blood in animal body be eliminated, and then injects 4% paraformaldehyde and be fixed.Intubate being inserted smoothly aorta and locating is the committed step determining perfusion success or failure.But there is no the intubate being specifically designed to animal hearts in zoopery at present, intubate used in an experiment is the bottle cork needle adopting disposable transfusion device mostly, and most advanced and sophisticated by removing it, then manual polishing sharpened edge forms.But this intubate cannot adapt to the animal hearts of different size, the animal hearts for different size needs the intubate making different size.Also there are two shortcomings in this intubate: one is that it is most advanced and sophisticated sharp keen and irregular, when being penetrated aorta, being easy to scratch blood vessel, directly causing perfusion failure.Two is limited length of this intubate, and being easy to comes off from aorta causes infusion liquid effectively can not enter aorta and affect organizing fixed effect.
Summary of the invention
The purpose of this utility model proposes a kind of device for animal perfusion, and it can be applicable to the animal hearts of different size; And intubate in experimentation can be avoided to come off and scratch blood vessel.
A kind of device for animal perfusion described in the utility model, comprise the intubate and conduit that are interconnected, the outer wall of described intubate is provided with scale, can show the length that intubate inserts heart and tremulous pulse; Described intubate is the Collapsible structure be socketed to form by least 2-section pipe material, can according to its length of the size adjustment of animal hearts.
Further, the front end of described intubate is the tapered portion that external diameter reduces gradually, and the front end of described tapered portion is provided with the spheroid of hollow, and the diameter of described spheroid is greater than the minimum outer diameter of described tapered portion.This structure can effectively prevent intubate from puncturing aortal accident, in experimentation, walk around aorta with silk thread and spheroid place knotting be fixed, can effectively prevent intubate from coming off.
Further, described intubate is made up of clear hard silica gel material, and transparent intubate is convenient observes and controls filling process.
The intubate that this utility model adopts is Collapsible structure, can be applicable to the perfusion of different size animal hearts, be provided with scale at the outer wall of intubate, accurately can show the length that intubate inserts heart and tremulous pulse; The front end of intubate is provided with spheroid, makes intubate locate convenient and heart and tremulous pulse can be avoided to sustain damage, so this utility model has applied widely, and easy to use, safe, efficient advantage.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of device for animal perfusion as shown in Figure 1, comprise the intubate 2 and conduit 3 that are interconnected, intubate 2 is made up of clear hard silica gel material, and conduit 3 is transparent soft plastic pipe, one end of conduit 3 is communicated with the tail end of intubate 2, and the other end of conduit 3 is connected with syringe 4.As shown in Figure 2, the diameter of intubate 2 is roughly 2.5mm, and the outer wall of intubate 2 is provided with scale 11, scale 11 with 0.5cm length for labelling; Intubate 2 is socketed to form by interior pipe 9 and outer tube 10, is Collapsible structure, by the length of interior pipe 9 scalable intubate 2 of sliding.The front end of intubate 2 is the tapered portion 7 that external diameter reduces gradually, the front end of tapered portion 7 is provided with the spheroid 8 of hollow, and the diameter of the cavity in spheroid 8 is 2mm, and the diameter of spheroid 8 is greater than the minimum outer diameter of tapered portion 7, spheroid 8 is provided with opening, and opening is communicated with conduit 3 by intubate 2.In the present embodiment, intubate 2 is socketed to form by 2-section pipe material, and in actual use, intubate 2 also can be socketed to form by three joints or more tubing.
The use procedure of the device of above-mentioned animal perfusion is: first postanesthetic animal is got dorsal position fixing after, open its thoracic cavity, expose heart and aorta 6.Cut off an osculum in apex, according to animal hearts size, regulate the length of intubate 2, then hold the root of intubate 2, aorta 6 is inserted along left ventricle 1 in the front end of intubate 2, and makes the length of intubate 2 in aorta 6 be 5mm.Then be separated aorta 6, walk around aorta 6 with silk thread 5 and be fixed in the spheroid 8 place knotting of intubate 2 front end.Finally cut off the left auricle of animal, push normal saline and tissue fixative solution through conduit 3 syringe 4.
Claims (3)
1., for a device for animal perfusion, comprise the intubate (2) and conduit (3) that are interconnected, it is characterized in that: the outer wall of described intubate (2) is provided with scale (11); Described intubate (2) is the Collapsible structure be socketed to form by least 2-section pipe material.
