Suitable, painless experimental situation respects its tremendous contribution made for the raw medical scientific undertakings of the mankind, is embodied in zoopery
One of main path of humanistic care.
Tracheal instillation is the main experimental methods of intrarterial or contamination, and most of experimental animal Intratracheal administration is at present
Invasive, and not can avoid esophagus and be strayed into.In addition, experimenter uses tracheotomy toward contact for the accuracy for guaranteeing administration,
Rat neck skin and Muscle disruption are made into tracheae exposure, drug instils via the notch of tracheae exposure, or with sharp sample introduction
Device punctures tracheae to realize the purpose of tracheal instillation administration.Such method has open wound, is easy to damage experimental animal, and
With the extension of time, zoogenetic infection rate increases, it is possible to cause animal dead, it is also possible to the accuracy of experimental result is influenced,
And it is unfavorable for long-time Intratracheal administration repeatedly；In addition, tracheotomy method is complicated, biggish manpower and time are needed, it can not
Suitable for high-volume zoopery.
Summary of the invention
It is simple that for the current state of the art, the technical problem to be solved by the utility model is to provide structures, user

A kind of tracheae epiglottis opening locator suitable for the noninvasive respiratory tract administration of rat of the utility model, structure letter
It is single, it is easy to make, using up big and down small conical hollow structure as retainer body, facilitate the irradiation of transmitted light source, it can
It exposes rat trachea sufficiently, drug drip process is enable to be completed rapidly and accurately；And retainer body upper end handle is set
Set, not only facilitate the gripping of locator, also facilitate will locator be inserted into rat oral procedures in be fixed and direction adjust.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one in the utility model；
Fig. 2 is the cutaway view Amplified image of locator longitudinal cross-section lower end in the utility model；
Fig. 3 is the structural schematic diagram of embodiment two in the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
It is as shown in Figure 1 to Figure 3 the structural schematic diagram of the utility model,
Appended drawing reference therein are as follows: height H, length L, retainer body 1, spherical structure 11, handle 2.
Embodiment one,
A kind of tracheae epiglottis opening locator suitable for the noninvasive respiratory tract administration of rat, includes by food-grade macromolecule
Retainer body 1 made of polymer material, retainer body 1 are in up big and down small conical hollow structure, retainer body 1
Height H is 5cm to 5.5cm, and the lower end diameter of retainer body 1 is 0.2cm to 0.4cm, the longitudinal cross-section of retainer body 1
Lower end be spherical structure 11；The upper end of retainer body 1 is laterally fixed with a handle 2.
Retainer body 1 and handle 2 are made of food-grade high molecular polymer；Such as food-grade PP, food-grade PE etc..
In embodiment, the upper end diameter of retainer body 1 is 1cm to 1.2cm.
In embodiment, the length L of handle 2 is 2cm to 3cm.
In embodiment, the width of handle 2 is 0.8cm to 1.2cm.
In embodiment, the section of handle 2 is ellipsoidal structure.
Using the retainer body 1 of up big and down small conical hollow structure, facilitate the irradiation of transmitted light source, rat can be made
Tracheae sufficiently exposes, and drug drip process is enable to be completed rapidly and accurately；And the setting of handle 2, not only facilitate locator
