Description
Technical field
The utility model relates to a kind of biomaterial freezing carrier, and in particular one exempts from the miniature freezing carrier of support.
Background technology
At present, known embryo vitrification freezing carrier has many kinds, and wherein open frozen, namely embryo directly contacts the frozen of liquid nitrogen, becomes the optimised form of embryo vitrifying freeze because cooling is fast.Its carrier usually adopted is the freezing rod type that front end has frozen carrier sheet (being called for short frozen), and it is simple to operate fast and efficient.
But current embryo vitrifying freeze bar and accordingly Load System storage area application efficiency are low.This reason is wherein: comprise and carry a bar, carry bar cover, carry bar cylinder, carry bar cylinder cap and carry bar tub system.Conventional carriers system forms by carrying bar, carrying bar cover, carry bar cylinder, carry bar cylinder cap and carrying bar tub.In existing apparatus, the mainly various freezing carriers that generation maximum space takies all separately must be furnished with protectiveness or identification support.Such as traditional aluminium shaft bar adds dress rod sleeve, and diameter reaches 1 centimetre, little freezing unit such as new again, is also be furnished with dress rod tube, and it is saved space efficiency and need further raising.
In general, what conventional cryopreservation methods was taked is multiple years bars put into together again one escort cylinder (as conventional embryo vitrifying freeze carry bar tub), which increase the space of escorting shared by cylinder; Simultaneously to escort in cylinder before little freezing unit has not successively all thawed at one, can not add new freezing unit at any time it in, otherwise can cause and store confusion, Gu Qisuo takes up space can not with to thaw and release new space; And multiple escort that cylinder is removed thaw in a large number time, surplus have the cylinder that escorts of little freezing unit to be returned to each well-bucket position of each liquid nitrogen container of original place.This return process easily occurs that position is returned and makes mistakes, for searching of thawing next time brings difficulty.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one and exempts from the miniature freezing carrier of support, increases the safety of operation, and reduce the space shared by carrier arrangement, what add each liquid nitrogen container amount of storage exempts from the miniature freezing carrier of support.
The utility model is achieved through the following technical solutions, the utility model comprises carrier and sleeve, described carrier comprise be connected as a single entity from top to bottom bar handle, connecting portion and frozen portion, described sleeve is the tubular structure of inner hollow, the top of sleeve is openend, and end is blind end, and the connecting portion of carrier and frozen portion to be inserted in sleeve by the openend of sleeve and be held on sleeve, bar handle is arranged on the openend of sleeve, and the top end face of bar handle is provided with index plane.
As one of preferred embodiment of the present utility model, the average diameter of the cross section of described bar handle and the index plane of top end face is more than or equal to 2.3mm, and the external diameter of sleeve is more than or equal to 2.3mm.
As one of preferred embodiment of the present utility model, more than the middle part of described sleeve offer at least one for being communicated with sleeve inner cavity and extraneous open communication.
As one of preferred embodiment of the present utility model, the hollow structure that described bar handle and connecting portion are formed in one.
As one of preferred embodiment of the present utility model, described frozen portion is thin slice.
As one of preferred embodiment of the present utility model, described thin slice is the groove structure of two lateral process medial recess.
As one of preferred embodiment of the present utility model, in the blind end of described sleeve, be provided with metal pouring weight.
The utility model has the following advantages compared to existing technology: the utility model overcomes existing micro-Frozen Biological device and the corresponding deficiency of loading technology in storage area utilization ratio thereof, small but independently can become freezing unit, do not need when storing to be placed in other protectiveness or identification support, overcome existing micro-Frozen Biological device and the corresponding deficiency of loading technology in storage area utilization ratio thereof, reduce the space shared by carrier arrangement significantly, especially for the embryo vitrifying freeze storing samples of supplementary reproduction, in each liquid nitrogen container amount of storage by increase about 4 ~ 8 times.

Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Fig. 1, shown in Fig. 2 and Fig. 3, the present embodiment comprises carrier 1 and sleeve 2, described carrier 1 comprises the bar handle 11 be connected as a single entity from top to bottom, connecting portion 12 and frozen portion 13, described sleeve 2 is the tubular structure of inner hollow, the top of sleeve 2 is openend, end is blind end, the connecting portion 12 of carrier 1 and frozen portion 13 to be inserted in sleeve 2 by the openend of sleeve 2 and are held on sleeve 2, bar handle 11 is arranged on the openend of sleeve 2, the top end face of bar handle 11 is provided with index plane 14, more than the middle part of sleeve 2 offer one for being communicated with sleeve 2 internal cavities and extraneous open communication 22, the hollow structure that bar handle 11 and connecting portion 12 are formed in one, sleeve 2 inside can be realized be communicated with extraneous, metal pouring weight 21 is provided with in the blind end of sleeve 2, for keeping the balance of whole sleeve 2 and carrier 1.
The average diameter of the cross section of bar handle 11 and the index plane 14 of top end face is more than or equal to 2.3mm, and the external diameter of sleeve 2 is more than or equal to 2.3mm.
