The bottom part of the bucket is sealed; a liquid through hole is formed in a part which is higher by over 3mm than the bottom part on the side wall of the bucket. The side-leakage type bucket for storing the minitype freezing unit is used for freezing; while the bucket is raised to the liquid nitrogen surface high above a liquid nitrogen tank, liquid nitrogen at the non-leakage height of the bottom part of the bucket can be used for delaying the violation time of a small amount of liquid nitrogen in a pole carrying cylinder; meanwhile, the interior of the bucket can be partitioned into a plurality of spaces (like 3-5) by using a partition sheet so as to reduce the numbers of the freezing units in each space, thus improving the speed of searching the special marks. With the combination of an upright post seat and the partition sheet, when the freezing unit quantity of an original zone is reduced more because of continuous unfreezing, the operation of the partition sheet is moved in the bucket, and compression of zone is realized under the condition that the partitioning of the freezing units in the original zone is not influenced so as to reserve a new space for new portioning.
Description
Technical field
The utility model relates to a kind of for the frozen device of biomaterial, relates in particular to a kind of a kind of well-bucket that is applicable to store the side leakage type of miniature frozen unit that carries out at biological and medical domain that micro-biological material vitrified frozen or other use when freezing.
Background technology
At present, known freezing carrier system has many kinds, can be divided into frozen tubular type and frozen rod-type two classes by main load units.The former is cylinder shape or part cylinder shape tubular container conventionally, and its one end is cecum, and the other end seals with screw thread or buckle form by block.This container is conventionally larger, and volume is generally more than 1 milliliter, and mostly by grid, within box-packed year, is stored on the layer-stepping carrier of liquid nitrogen container.This form of the frozen employing of current most cells; Latter is rod-like device, comprise: the straw shape vessel form that (1) is elongated, biological material specimens that can frozen 1-5 hectolambda, (2) pipe end is by the further elongated form of drawing-down, utilize elongated portion to carry out frozen, can be used for the frozen of several microlitre samples, (3) also have the non-vessel form of elongated rod-shaped, its front end has frozen carrier sheet, can adhere to and load number microlitre with interior biomaterial on this sheet.It is frozen that latter two form all belongs to micro-example, applies more in the ovum of cultivating in vitro or embryo's glass frozen preservation.For ovum or embryo's glass freezing, also have the trace of frozen loop type frozen, with the liquid containing ovum or the embryo that adhere on microfilament ring, then be positioned over protection frozen in tubular container.
Yet the frozen device of above-mentioned various trace (in number microlitre) sample does not take memory space relatively still less than constant (hundreds of microlitres cause several milliliters) at present, has caused storage area application efficiency low.This reason is wherein: the loading of micro-example must meet the simple and convenient needs that wait of operation of identification with taking also, therefore except sample carrier loading station itself, also must there be other dependency structure and device, to help loading, sealing, mark, classification storage and the access of sample convenient etc., the coupling of these structures and device has at present formed larger space.
Take that to the embryo of culture in vitro, to carry out freezing in Issues of Human Assisted Reproductive Technologies be example, its embryo's glass freezing usually adopts frozen rod type (following special title embryo cryopreservation carries bar or is called for short and carries a bar), the non-vessel form of elongated rod-shaped for example, be also form easily of the save space of current embryo cryopreservation and operation, comprise and carry a bar (one end has frozen), carry bar cover, carry bar cylinder, carry bar cylinder cap and carry bar cylinder frame system.Fig. 1 is conventional carriers system schematic, by carrying bar 1 ', carry bar cover 2 ', carry bar cylinder 3 ', carry bar cylinder cap 4 ' and carrying bar cylinder frame 5 ', forms.As shown in Figure 1, carry bar 1 ' front end and insert in year bar cover 2 ', then be loaded into together in year bar cylinder 3 ', and carry bar cylinder 3 ', by clamping, carried on bar cylinder frame 5 ', its top has is carried the clamping bar cylinder cap 4 ' that carries of bar cylinder frame 5 ' and is covered, and prevents from carrying dropping out of bar 1 '.Wherein carry on bar frozen for placing embryo, its one end quilt cover of placing embryo is uploaded bar cover, to protect this section not damaged by external force; Carrying bar cylinder carries bar and carries bar cover for loading; Also have an aluminium alloy frame to carry bar cylinder frame, for clamping year bar cylinder and carry bar cylinder cap (carry bar cylinder cap do not drop out cylinder for the protection of article in cylinder outer).Carry on bar and can post biomaterial information labels.Carry bar cylinder frame upper end and can stick the information labels such as frozen position, form a frozen unit.Generally a plurality of samples that derive from same patient are carried to bar and be loaded in same or a plurality of frozen unit, the embryo in different patients source can not load in mixture in same frozen unit, is beneficial to identity marks and resolution.
As above year bar cylinder frame and clamping carry bar cylinder and carry not only the have an appointment thickness of 1-1.5 cm diameter of bar cylinder cap, also has approximately 29 centimetre lengths altogether.In this covering device, produce two aspects that have that maximum space takies: (1) is to carry a bar cylinder frame, because it must than carry bar cylinder greatly just can hold clamping year bar cylinder and with carry bar cylinder etc. large carry bar cylinder cap, and this clamping necessity is to fix and carries a bar cylinder cap and make it in carrying a bar cylinder openend, to protect the bar that carries carrying in bar cylinder not drop out; (2) be to carry bar cover, because it must just can put this end than the one end of placing embryo on year bar is large, thereby usually produced than carrying the thicker space hold of bar.This makes to carry bar cylinder must have the internal diameter of thick (approximately 1 centimetre) for meeting common useful load (6-8 embryo needs 3-4 root to carry bar).
In general, a patient's embryo at least needs to carry bar cylinder frame with one, according to transplanting, need, every frozen amount of carrying bar is 1-3 piece of embryo, and a quantity of carrying bar wound packages year bar is between 1 to 4, when client need frozen approximately 8 and following embryo, it need take a support bar cylinder frame, and surpassing 8 needs to take 2 or to upload bar cylinder frame.This carrier system can facilitate loading when freezing, finds rapidly and carry bridge and extract out and carry a bar from carrying carrying bar cylinder of bridge clamping while also conveniently thawing from liquid nitrogen container.Yet, upper convenient although this system is used, taken many spaces.In the liquid nitrogen container of 47 liters of 10 well-buckets, each well-bucket only approximately can be put into 26-28 support bar cylinder frame, with each patient, at least needs a support bar cylinder frame to calculate, maximum frozen approximately 28 patients' of each well-bucket embryo.The liquid nitrogen container of 47 liters of 10 well-buckets can be deposited at most approximately 280 patients' embryo.Concerning a relatively large supplementary reproduction center, if on average monthly surpass 500, get the ovum cycle, even if consider to count the space that the embryo of thawing discharges in, the required liquid nitrogen container of its newly-increased frozen embryo may need to increase by one average every month, within several years, gets off and will cause taking of super large space.The development of Zhe Duiyige supplementary reproduction mechanism causes restriction.Therefore, current micro-Frozen Biological device and the space utilization efficiency of corresponding loading technology thereof are relatively low, also cannot meet the frozen and development of the sample of large-scale.
On the other hand, in freezing or when operation of thawing, in liquid nitrogen volatilization steam fog carry bar cylinder frame aluminum alloy material compared with the easier condensation air of other plastic material in steam and freezing, this usually causes label segment to expose being condensed after liquid nitrogen certain hour ice covering, causes the inconvenience of operation.
In order to overcome, take existing micro-Frozen Biological device and the technology of loading accordingly thereof in the deficiency aspect storage area utilization ratio, people will carry out microminiaturization for the frozen frozen unit of biomaterial, with ensure freezing loading, mark, storage, resolution and taking-up and thaw etc. each simple and convenient in, can also reduce more significantly the shared space of carrier arrangement, make each liquid nitrogen container amount of storage (case load that refers to storing samples for the embryo vitrifying freeze of supplementary reproduction) increase about 3-4 doubly.Owing to carrying a bar cylinder, attenuate, when frozen, the amount of liquid nitrogen of carrying in bar cylinder is few, and well-bucket carries the easily volatilization completely of liquid nitrogen in bar cylinder while taking out, and the frozen failure of biomaterial in the protection in liquid nitrogen, is not easily caused in the frozen position of biomaterial.
