Description
Technical field
The utility model relates to a kind of boar semen application of sample instrument, relates in particular to a kind of boar semen sample injector in batches.
Background technology
Boar semen technology and application are difficult points of freezing field of biology always.At present boar semen generally adopts the dropper method to make particle at the fluorine plate to freeze essence, and to freeze efficient very low yet this method is dripped.According to freezing the refining requirement of doing, a time of freezing is generally controlled within 1 min, freezes the 30-40 grain and can only drip at most in 1 min.The so low smart production efficiency of freezing does not only reach production popularization requirement far away, and can cause very big adverse effect to freezing extract Iuality yet.Because the pig insemination dose is very big, this just requires to produce in a large number and freezes essence, and freeze speed according to dripping at present, every batch can only drip and freezes about 40, consuming time but the needs more than 30 min, 6 batches freeze and just need to get off the above time of 3 h so, during seminal fluid be in always that height oozes, in the low temperature environment, sperm quality is caused than major injury, freeze the back sperm quality thereby reduce.Therefore if freeze and smartly apply producing, except frozen solution, freezing procedure are arranged preferably, also must make freeze essence can be fast, batch process.
Summary of the invention
The utility model provides a kind of dripping according to the pig seminal fluid to freeze and custom-designed boar semen batch sample injector in order to solve above-mentioned the problems of the prior art.
The utility model is to address this problem the technical scheme of taking to be:
Boar semen of the present utility model is sample injector in batches, comprises the external container and the internal container that connect together, is arranged on the cystosepiment in the internal container, and dropper is fixedly arranged on the cystosepiment, and stretch out the lower end of dropper container and external container downside internally; Be provided with a circular hole corresponding to each dropper on the upper side of internal container; The upper face center of external container is provided with an aspirating hole, takes out air gun head and is connected in the aspirating hole.
The described air gun head upper end of taking out is connected with syringe.
Described external container and internal container are plastic containers, and the equal opening of downside.
The thickness of described cystosepiment is consistent with the degree of depth of internal container, and number row dropper is fixedly arranged.
The diameter of described circular hole is consistent with the bore of dropper upper end.
Advantage and the good effect that the utlity model has are:
Boar semen of the present utility model is sample injector in batches, is to drip according to the pig seminal fluid to freeze and custom-designed, selects common experiment material for use, the many volley of rifle fires device that forms through processing, design and assembling.Make when pig is frozen essence and need use the mixed liquor that drips seminal fluid and protection liquid in dropper each aperture on the fluorine plate, of short duration stifling back is dropped in the liquid nitrogen and is carried out superfreeze on liquid nitrogen.The utility model is based on the position of arranging between fluorine plate size and the aperture and custom-designed boar semen sample injector in batches, realized that pig freezes the smart purpose of fast, producing in batches, improved droplet to freeze efficient, satisfied the actual demand in producing.Proved that in production and practice process this utility model can make pig freeze the essence batch, produce fast, freezes essence for pig and has solved technical barrier in the production popularization with application.

Embodiment
Followingly with reference to drawings and Examples the utility model is described in detail.
Make pig in the production and freeze essence and need use the fluorine plate, the fluorine plate gauge lattice size of commercial production is certain substantially.Several rows of little shrinkage pool is arranged on the fluorine plate, make pig is dripped seminal fluid and protection liquid when freezing essence in each aperture with dropper mixed liquor, it is freezing to carry out ultralow temperature (196 ℃) on liquid nitrogen in the input liquid nitrogen of of short duration stifling back.The utility model just is being based on arrangement position between fluorine plate size and the aperture and custom-designed boar semen batch sample injector.
Fig. 1 is the boar semen of the present utility model vertical view of sample injector in batches; Fig. 2 is boar semen of the present utility model sample injector sectional side view in batches.As depicted in figs. 1 and 2, boar semen of the present utility model is sample injector in batches, comprises the external container 1 and the internal container 5 that connect together, is arranged on the cystosepiment 6 in the internal container, number row's droppers 7 are fixedly arranged on the cystosepiment 6, and stretch out the lower end of dropper 7 container 5 and external container 1 downside internally.
During making, carry out mark according to the aperture arrangement position on the fluorine plate on the cystosepiment 6 earlier, inserting 1mL rifle head then as dropper 7.Insert 30 droppers (can also increase by 30 as required) at cystosepiment 6, and the liquid in each dropper can drop in accurately all in the aperture on the fluorine plate.So once can drip the 30-60 grain, and traditional dropper once can only drip 1, thereby this contrive equipment makes to drip and freezes efficient and improved 30-60 doubly.
Internal container 5 is plastic containers, and open lower side, size are slightly smaller than the size of cystosepiment 6, thereby cystosepiment 6 can be fixed in the internal container 5 tightly.The consistency of thickness of the degree of depth of internal container 5 and cystosepiment 6 has increased this design overall aesthetics.Be provided with a circular hole 3 corresponding to each dropper 7 on the upper side of internal container 5, the diameter of circular hole 3 is consistent with the bore of dropper 7 upper ends.Thereby guarantee the uniformity of suction in each dropper.
External container 1 also is plastic containers, and open lower side.Its size is a bit larger tham the size of internal container 5, its container depth and cystosepiment consistency of thickness.The upper face center of external container 1 is provided with an aspirating hole 2, takes out air gun head 4 and is connected in the aspirating hole 2.Taking out air gun head 4 is rifle heads of a 100uL.This rifle head upper end can link to each other with the syringe of different size, is used as air extractor.
The boar semen of the present utility model course of work of sample injector in batches is as follows: the first step extend into the dropper of sample injector in the mixed liquor that fills seminal fluid and protection liquid; Second goes on foot, and slowly upwards twitches the piston of syringe, and at this moment under the effect of negative pressure, mixed liquor will be drawn in each dropper uniformly; The 3rd step, sample injector is taken out mixed liquor, dropper is aimed at aperture pushing syringe piston gently on the fluorine plate, at this moment under positive pressure, the mixed liquor in the dropper is slowly blown out, splash in each aperture.Every like this suction, tell once can drip and freeze the 30-60 grain and freeze essence, thus realize pig freeze smart fast, produce in batches.
