The vaginal secretion sampler for the mice is simple in structure and low in cost; the operation of sampling the vaginal secretion of the mice is quite simple and convenient for one person; the vagina of the mice is not injured; the vaginal mucosa of the mice is protected, so that the objectivity of the acquired experimental results is ensured.
Description
Technical field
This utility model relates to a kind of apparatus for mouse experiment, particularly relates to a kind of mouse vagina secretion sampler.
Background technology
Zoopery is the important step of medical research, can be used for many-sided researchs such as physiology, pathology, pharmacology and psychology, in medical science, many experiments can not or there is no need directly on human body, to study, therefore conventionally carry out correlational study by setting up a similar animal model.
Mice is a kind of mammal, and gene is similar with the mankind, and the features such as it has, and fertility is strong, rate of development fast, early sexual maturity, therefore it becomes a good animal model of research reproductive system.After mice sexual maturity, under the adjusting of mouse hypothalamus, hypophysis and ovary, the variation of estrogen and progestogen generating period, under functions of hormones, also there is the variation of respective cycle in the vaginal mucosa of mice and uterus, be commonly referred to the oestrous cycle, the feature in each stage of oestrous cycle can be distinguished with mouse vagina secretions smear, with the research of being correlated with.
At present, when sampling mouse vagina secretions, generally adopt glass dropper or cotton swab, but because mouse vagina is very carefully narrow, and the diameter of glass dropper or cotton swab is relatively excessive, therefore be easy to lose mouse vagina mucosa, thereby cause mouse vagina to infect, affect the observation of normal periodic.
The Chinese utility model patent description that is 200920226917.8 as application number discloses a kind of Multifunctional mouse vagina douche, by garment bag and screw socket silicone rubber tube, formed, garment bag is round and smooth conical ring sleeve pipe, screw socket silicone rubber tube is arranged in garment bag, garment bag bottom is in the form of annular discs, and garment bag and screw socket silicone rubber tube adopt high medical-grade plastics material transparent, good springiness to make, and are carved with scale on silicone rubber tube, the design of spiral mouth, to connect and to use with multiple utensil.But, this Multifunctional mouse vagina douche complex structure, cost is high, and also needs to match and could use with other lavation equipment (as syringe, rifle head, suction nozzle etc.) when operation, very trouble.
Utility model content
The defect of prior art and various weak point in view of the above, the technical problems to be solved in the utility model is to provide a kind of mouse vagina secretion sampler simple in structure, easy-operating.
For achieving the above object, this utility model provides a kind of mouse vagina secretion sampler, comprise suction nozzle and the suction pipe that is transparence, described suction pipe comprises the hand-held pipe that is located at the insertion tube of front end and is located at rear end, described insertion tube and hand-held pipe are structure as a whole, the rear end of described hand-held pipe is connected with suction nozzle, and the diameter of described insertion tube is 1-2mm, and the diameter of described hand-held pipe is 8-10mm.
Preferably, the material of described suction pipe is polypropylene.
Preferably, the material of described suction nozzle is silica gel.
Further, the surface of described suction pipe is provided with containing mark line.
Preferably, the length of described insertion tube is 2-3cm, and the length of described hand-held pipe is 4-5cm.
The mouse vagina secretion sampler that this utility model relates to has following beneficial effect:
This mouse vagina secretion sampler is simple in structure, and cost is low, and when sampling mouse vagina secretions, operation is very simple and convenient; one man operation; also can not damage mouse vagina, protect mouse vagina mucosa, and then guarantee the objectivity of the experimental result obtain.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be elaborated to this patent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another embodiment of the present utility model.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this utility model provides a kind of mouse vagina secretion sampler, comprise suction nozzle 1 and the suction pipe 2 that is transparence, described suction pipe 2 comprises the insertion tube 21 that is located at front end and the hand-held pipe 22 that is located at rear end, described insertion tube 21 and hand-held pipe 22 are structure as a whole, the rear end of described hand-held pipe 22 is connected with suction nozzle 1, and the diameter of described insertion tube 21 is 1-2mm, and the diameter of described hand-held pipe 22 is 8-10mm.
In this mouse vagina secretion sampler, insertion tube 21 is an elongated tubular, for inserting mouse vagina; Described hand-held pipe 22 convenient operation persons draw and carry normal saline and hand-held this sampler by suction nozzle 1.Because insertion tube 21 diameters are little, thus after inserting in mouse vagina, can not damage mouse vagina mucosa, therefore guarantee correctness and objectivity to mice normal periodic observed result.In the present embodiment, the length of described insertion tube 21 is 2-3cm, and the length of described hand-held pipe 22 is 4-5cm.
In addition, in order to control the degree of depth in insertion tube 21 insertion mouse vaginas, the catch 4 of an annular can be set on insertion tube 21, as shown in Figure 2, this catch 4 is also transparence, by polypropylene, is made.
Preferably, the material of described suction pipe 2 is polypropylene, adopts polypropylene to make suction pipe 2, can make suction pipe 2 nontoxic, high temperature resistant, high transparent, and the roundness of suction pipe 2 is good.
Preferably, the material of described suction nozzle 1 is silica gel.
Further, the surface of described suction pipe 2 is provided with containing mark line 3, can be the amount that operator draws normal saline effective reference is provided.In the present embodiment, described containing mark line 3 is located at apart from suction pipe 2 free-end 20u, 1ml, 2ml place.
