Abstract
The utility model discloses a mouse fixing device which comprises a cylinder body. The bottom end of the cylinder body is closed, and a rotary cover covers a top end cover. Filler is filled at the bottom of the cylinder body, a small hole is formed in the rotary cover, and the diameter of the small hole is matched with the diameter of the root portion of the tail of a mouse. The mouse fixing device has the advantages that the structure is simple, production cost is low, the mouse is conveniently fixed, meanwhile, the tail of the mouse is left outside the fixing device so that the mouse is prevented from biting an experimenter, and tail vein injection, tail vein blood fetching and tail breaking and blood fetching of the mouse can be conveniently performed on the mouse by the experimenter. The mouse fixing device is convenient to use and easy to carry. In addition, the mouse fixing device can also be used as a fixing device for absorbing blood by mosquitoes, the mouse fixed in the fixing device can be used for repeated blood feeding, and cost in breeding the mosquitoes is effectively reduced.
Description
Technical field
This utility model relates to a kind of apparatus that fetters animal, is specifically related to a kind of little rat holder.
Background technology
Mice is a kind of medical research laboratory animal commonly used, be multidisciplinary laboratory animals commonly used such as medical science, biology, pharmacology, pathology, but often carry multiple virus in the mice body, if bitten by mice, can influence the healthy of experimenter, even cause breaking out of infectious disease, need protect it during extracting bites, administration can be directly arrested in of short duration operations such as intraperitoneal administration, but during as operations such as need tail vein injection or tail venesectioies, need the long period to fix, need to use corresponding little rat holder.
In addition, the artificial cultivation of mosquito also mainly adopts the method for white mice live body blood supply to breed to go down to posterity.
At present, usually use the fixedly instrument of mice of square plank conduct, the mice extremity are diagonal with rubber band to be strained and fixed in four jiaos of plank, this kind fixing means is difficult to operation, need mice to be fixed through repetition training, control method complexity, expensive, and also mortality of mice is very high, also can the extremity incompleteness can't continue to use even survive individually, cause unnecessary waste.
The shortcoming of prior art is: present normally used mice holder control method complexity, expensive, and also mortality of mice is very high, also can the extremity incompleteness can't continue to use even survive individually, causes unnecessary waste.
The utility model content
The purpose of this utility model provides a kind of little rat holder easy and simple to handle, be convenient to mice carry out tail vein injection, the tail vein gets blood and blood is got in docking, can also provide for the mosquito of culturing and feed blood repeatedly.
For achieving the above object, this utility model is explained a kind of little rat holder, comprise cylindrical shell, the sealing of described cylindrical shell bottom, spiral cover is stamped on the top, its key is: in described cylindrical shell bottom implant is housed, has aperture at described spiral cover, described hole diameter and mouse tail root diameter (RD) size are complementary.
In fixing mice, cylindrical shell is set level, open spiral cover, long according to the mice body, add implant toward the cylindrical shell bottom, live nozzle with stick shift, mention mouse tail, allow it oneself pierce from the nozzle end, hold up cylindrical shell then, mouse tail is passed from spiral cover, screw spiral cover, finish fixing to mice, the holder of She Zhiing can be fixed mice like this, and mousetail is stayed the outside, injection for intravenous or get blood and use, this fixer structure is simple, and is easy to use, to operation such as mouse tail vein injection or tail venesection the time, can effectively prevent the mice experimenter that bites.
Outer wall at described cylindrical shell has at least one hello blood hole.
It is fixing that the mice of suitable size is put into this holder, the blood hole of offering of feeding is used for mouse breathing and feeds blood repeatedly to mosquito, so fixedly mice can avoid mice incomplete or dead because of the binding extremity, can't continue as mosquito hello blood is provided, cause unnecessary waste, can effectively reduce the expense that mosquito is cultured.
Described diameter of feeding the blood hole is 5mm.
Hello the blood hole of such size is set, can is satisfying mouse breathing and mosquito fed under the situation of blood, offer the blood hole of feeding as much as possible, it is more convenient that the mosquito of feasible breed is sucked blood.
Described cylindrical shell is centrifuge tube.
As cylindrical shell, one side is to gather materials on the spot in laboratory, and is very convenient with centrifuge tube; Production cost is low on the other hand, low price.
Described implant is absorbent cotton or spitball, is used for the action of restriction mice, but can injure mice.
Remarkable result of the present utility model is: simple in structure, production cost is low, make things convenient for the fixing of mice, mousetail is stayed outside this holder simultaneously, can prevent the mice experimenter that bites, also be convenient to the experimenter and mice carried out tail vein injection, tail vein are got blood and blood is got in the mice docking, easy to use, be easy to carry about with one; Also can be used as the fixture that mosquito is sucked blood in addition, the mice that is fixed in this holder can be used for feeding repeatedly blood,
Effectively reduced the expense that mosquito is cultured.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of spiral cover.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of little rat holder, comprise cylindrical shell 1, the sealing of described cylindrical shell 1 bottom, spiral cover 2 is stamped on the top, in described cylindrical shell 1 bottom implant 3 is housed, and described implant 3 is absorbent cotton or spitball, have aperture 4 at described spiral cover 2, described aperture 4 diameters and mouse tail root diameter (RD) size are complementary.
Outer wall at described cylindrical shell 1 has at least one hello blood hole 5, and described diameter of feeding blood hole 5 is 5mm.
Present embodiment has four described blood holes 5 of feeding, and adjacent two spacings of feeding between the blood hole 5 are 1cm.
Described cylindrical shell 1 is centrifuge tube.
Although below by reference to the accompanying drawings preferred embodiment of the present utility model is described; but this utility model is not limited to the above-mentioned specific embodiment; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of this utility model aim and claim; can make multiple similar expression; as: change implant 3 into wood flour etc., such conversion all falls within the protection domain of the present utility model.
