Abstract
The utility model discloses a rat trachea administration intubation tube comprising a hollow hose that is internally sheathed with a supporting metal wire, and the hollow hose is in sliding fit with the supporting metal wire. The supporting metal wire is longer than the hollow hose. The intubation tube is simple in structure, convenient for use, high in the success rate of intubation without damaging the organism of a rat, wide in using range and easy for promotion, and has good economical benefit.
Description
One, technical field: this utility model relates to a kind of intubate, particularly relates to a kind of rat trachea medicine-feeding canula.
Two, background technology: in some animal (as rat) experiment, need prepare animal model by the trachea administration.Traditional method is that rat neck skin, flesh layer and fascia are cut off, and exposes trachea, carries out puncture injection, is a kind of traumatic operation, increases infection chance, and is bigger to the human body injury.The at present employing looked at direct cannulation under the rat glottis straight more, carries out the medicine injection.Used intubate has plastic flexible pipe, rustless steel intubate etc.It is light and soft that plastic flexible pipe has material, and the rat trachea is stimulated little advantage, but because of it lacks hardness, have the low defective of successful intubation; The rustless steel intubate has the convenient advantage of inserting, but harder because of its material, and oral cavity, the tunica mucosa tracheae of rat had than strong stimulation, has increased the influence of non-empirical factor to experimental result.
Three, utility model content
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, successful intubation is high and do not damage the rat trachea medicine-feeding canula of rat human body.
The technical solution of the utility model is: a kind of rat trachea medicine-feeding canula, contain hollow hoses, and be set with support wire in the described hollow hoses, the two is slidingly matched.
Described support wire is longer than described hollow hoses.The length of described hollow hoses is 10cm, and its intracavity diameter is 1mm, and the length of described support wire is 11cm, and its diameter is 0.8mm.
The beneficial effects of the utility model are:
1, this utility model adopts hollow hoses and support wire to combine, this hollow hoses caliber is little, and material is light and soft, can alleviate the stimulation to the rat human body, this support wire does not directly contact the rat trachea, certain support force and deformation force are arranged, be easy to insert the trachea chamber and do not injure the rat human body, the successful intubation height, extract tinsel out, connect syringe and just can carry out drug administration by injection, easy to operate, and the operating time is short.
2, this utility model support wire is longer than hollow hoses, is convenient to extract from hollow hoses and fix, and can realize repeat administration.
3, this utility model scope of application is wide, has both gone for rat, can also be applicable to other animals, is easy to promote, and has good economic benefit.
Four, description of drawings:
Fig. 1 is the structural representation of rat trachea medicine-feeding canula;
Fig. 2 is the left view of rat trachea medicine-feeding canula shown in Figure 1.
Five, the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, rat trachea medicine-feeding canula contains hollow hoses 1, is set with support wire 2 in this hollow hoses 1, and the two is slidingly matched.
During use, support wire 2 is sleeved in the hollow hoses 1, its front end does not stretch out hollow hoses 1, and hollow hoses 1 is stretched out in the rear end, and the operator holds hollow hoses 1, make hollow hoses 1 and support wire 2 relative fixed simultaneously, then, under direct-view, hollow hoses 1 and support wire 2 are inserted rat trachea intracavity, because support wire 2 is steel wire (also can be iron wire, copper wire or the like), have certain support force and deformation force, thereby the successful intubation height.After hollow hoses 1 is inserted into the position, unclamp hands, extract support wire 2 out from the outer end of hollow hoses 1 again, connect syringe in the outer end of hollow hoses 1 at last, can carry out administration.
The length ratio that changes material category, change hollow hoses and the support wire of support wire can be formed a plurality of embodiment, is common variation of the present utility model, does not describe in detail one by one at this.
Claims (3)
1. a rat trachea medicine-feeding canula contains hollow hoses, and it is characterized in that: be set with support wire in the described hollow hoses, the two is slidingly matched.
