The utility model relates to a kind of novel embryo vitrifying freeze and loads straw; comprise the protective cover loading straw and coordinate with loading straw; the cross sectional shape loading straw and protective cover is rectangle; protective cover mouth place is connected with outward extending importing handle; the cross sectional shape importing handle is Qian type; import on handle and have positioning through hole, load on straw and be provided with the projection coordinated with the positioning through hole imported on handle.The utility model is provided with caster assembly therefor on protective cover; caster assembly therefor has positioning through hole; load on straw and be provided with the projection coordinated with the positioning through hole imported on handle; this projection can be hung mutually with positioning through hole; can effectively prevent sleeve pipe from deviating from and lose embryo or egg mother cell; can also positioning action be played, make loading straw front end be not easy to touch the bottom of protective cover, reduce embryo or ovum and to come off loss.The utility model has does not need tweezers to assist, and loads straw and can enter protective cover fast, easy to operate advantage.
Description
Technical field
The utility model relates to a kind of novel embryo vitrifying freeze and loads straw.
Background technology
Vitrification is a kind of method of snap frozen embryo or ovum, is subject to extensive concern along with the development of auxiliary procreation technology.It is fast that this technology has chilling rate, and avoid cold crystalline substance to be formed, reduce and coldly melt damage and simple operation and other advantages, by clinical observation, the method can improve the survival rate after embryo or egg freezing recovery and Pregnancy Success rate.
It is the smooth freezing blade in the front end of being made up of macromolecular material that existing glass freezing carries bar, egg cell or embryo are placed on blade carry out freezen protective in the process used, carry out recovery of thawing when needing after being also convenient to simultaneously, but this carrier arrangement completes under the supervision of normal eyesight, blade liquid nitrogen with cell or embryo is carried out snap frozen, and outside it plastic tube on cover, and then put in freezing liquid and preserve.When applying above-mentioned carrier arrangement, Problems existing is: for avoiding light to the light injury of ovum or embryo, refrigeration operation is all operate under low light environment, the handle of freezing blade is longer, liquid nitrogen is vaporized generation mist in atmosphere, when requiring quick encased pipe, the freezing straw mouth of pipe is less, eyesight and time is taken very much when inserting straw, simultaneously, owing to cannot again enter in air after embryo or egg freezing, the process putting sleeve pipe must be carried out in liquid nitrogen, in liquid nitrogen, temperature is-196 degrees Celsius, staff cannot operate, this just needs to use tweezers to assist, after clamping sleeve pipe with tweezers, the bar that carries that embryo or ovum are housed is loaded sleeve pipe by another hand, if beginner or divert one's attention a little, ovum on blade or embryo will be touched the mouth of pipe or the bottom of sleeve pipe because of carelessness, embryo or ovum is caused to lose.Because sleeve pipe is fixed on year bar without other any devices, sleeve pipe only relies on frictional force with year linking of bar, therefore can cause coming off of sleeve pipe, and embryo or ovum also can be caused to lose.
Summary of the invention
The technical problems to be solved in the utility model is: provide one not need tweezers to assist, load straw and can enter protective cover fast, easy to operate novel embryo vitrifying freeze loads straw, to solve above-mentioned prior art Problems existing.
The technical scheme solved the problems of the technologies described above is: a kind of novel embryo vitrifying freeze loads straw; comprise the protective cover loading straw and coordinate with loading straw; described loading straw and the cross sectional shape of protective cover are rectangles; described protective cover mouth place is connected with outward extending importing handle; the cross sectional shape of described importing handle is Qian type; import on handle and have positioning through hole, described loading straw is provided with the projection coordinated with the positioning through hole imported on handle.
The length L of described importing handle is 5 ~ 8cm.
Described loading straw is also provided with liquid nitrogen point of observation.
Described loading straw is also provided with Sign Board.
Owing to adopting said structure, the utility model has following beneficial effect:
1, the utility model is provided with caster assembly therefor on protective cover; caster assembly therefor has positioning through hole; load on straw and be provided with the projection coordinated with the positioning through hole imported on handle; this projection can be hung mutually with positioning through hole; with existing be only rely on frictional force between straw with protective cover fixing mode compared with, can effectively prevent sleeve pipe from deviating from and losing embryo or egg mother cell.And load the projection of straw and hang mutually with positioning through hole, can also play positioning action, make loading straw front end be not easy to touch the bottom of protective cover, minimizing embryo or ovum come off loss.
2, caster assembly therefor of the present utility model is longer; and be Qian type; there is guide effect; operator can use hand direct control; load straw to be first placed on caster assembly therefor; push again in protective cover, do not need the auxiliary equipment such as tweezers can complete the whole process of tubulature, avoid using auxiliary equipment and make straw front end meet other place and cause embryo or ovum to lose.
3, the cross sectional shape of loading straw of the present utility model and protective cover is rectangle, is conducive to positioning through hole and protruding setting on the one hand, conveniently marks embryo or ovum relevant information, such as patient name, freezing date etc. on the other hand.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of the novel embryo vitrifying freeze loading straw of the utility model is further described.

Embodiment
Embodiment 1: a kind of novel embryo vitrifying freeze loads straw, comprise the protective cover 1 loading straw 3 and coordinate with loading straw, the straw rear end 33 that described loading straw 3 comprises the straw front end 32 for loading embryo or ovum and connects as one with straw front end, described loading straw 3 and the cross sectional shape of protective cover 1 are rectangles, described protective cover mouth place is connected with outward extending importing handle 2, the cross sectional shape of described importing handle is Qian type, the length L importing handle 2 is 5 ~ 8cm, import on handle and have positioning through hole 21, described loading straw is provided with the projection 31 coordinated with the positioning through hole imported on handle.The straw rear end 32 of described loading straw 3 is also provided with liquid nitrogen point of observation 4.The side of described loading straw is also provided with Sign Board (not shown in FIG.), for marking embryo or ovum relevant information.
Use procedure: the hand-held straw rear end 33 of operator; be dipped into rapidly in liquid nitrogen after the good embryo of device or ovum, first loading straw be placed on caster assembly therefor, then push in protective cover; the projection of loading straw is hung mutually with the positioning through hole imported on handle, namely completes tubulature.And then its put into liquid nitrogen under preserve.Resuscitation process: make embryo or ovum rest in liquid nitrogen; the projection of loading straw is shifted out outside liquid nitrogen with the positioning through hole imported on handle; loading straw is separated with handle; after being dropped into protective sleeve; again the loading straw front end that embryo or ovum are housed is immersed in thawing solution; embryo is completed or ovum thaws, to embryo or ovum recovery according to thaw routine.
