Abstract
Freezing carrier of preserving of oocyte and embryonal glass ization belongs to procreation biology technical field. The utility model relates to a solve present germ cell and preserve the carrier because the structure is complicated, appear loosely when certain parts, cause the problem that the cell loses easily. It includes straw, top stopper and sealed lid, the last port of top stopper sealing connection straw, and the bottom of straw is needle -like, is provided with a ring section of thick bamboo of taking the cavity on first section the lateral wall of straw, sets up the metal block in the ring section of thick bamboo, and straw inner chamber and the ring cavity air vent on through the straw lateral wall communicates with each other, through threaded connection, the straw bottom is located sealed lid between a sealed lid and the ring section of thick bamboo. The utility model is used for freezing oocyte and embryonal glass ization are freezing preserves.
Description
Technical field
This utility model relates to the vitrificated cryopreserration carrier of oocyte and embryo, belongs to biology of reproduction technology neck
Territory.
Background technology
Oocyte, embryo vitrifying freeze Techniques of preserving are the most effectual ways preserving sexual cell at present, and it is not only
The continuity of rare species can be ensured, moreover it is possible to ensure diversity of organism.In the society of Modern High-Speed development, for uncommon
Hope and postpone child's date of birth, and need to preserve in advance all demands of sexual cell for suffering from the Mr. and Mrs of disease, will be raw
Cell colonization carries out freezen protective and all has great importance.
During sexual cell carries out freezen protective, it is female thin that the design of vitrificated cryopreserration carrier directly affects ovum
The freezen protective efficiency of born of the same parents and embryo.Current conventional micro drop method preservation carrier is few due to the freezing liquid comprised such that it is able to fall
Low cytotoxicity, is the most just widely used.But it is complicated, at process of cryopreservation because forming structure that this microdroplet preserves carrier
In, not only can increase the probability of operator's error；And after carrier puts into liquid nitrogen, also it is easily caused all parts loose,
Cause cell loss.
Summary of the invention
This utility model purpose be in order to solve existing sexual cell preserve carrier due to structure complicated, when certain parts goes out
Problem that is existing loose, that easily cause cell loss, it is provided that the vitrificated cryopreserration carrier of a kind of oocyte and embryo.
The vitrificated cryopreserration carrier of oocyte described in the utility model and embryo, it includes that suction pipe, top are filled in and close
Capping,
Top plug is tightly connected the upper port of suction pipe, and the bottom of suction pipe is needle-like,
Be provided with the ring cylinder of band cavity on the lateral wall of the upper semisection of suction pipe, metal derby be set in ring cylinder, suction pipe inner chamber with
Ring cylinder cavity is communicated by the passage on sidewall of suction pipe；
Sealing and be threaded connection between lid and ring cylinder, suction pipe bottom is positioned at sealing lid.
Described metal derby is aluminium block or Al alloy block.
Advantage of the present utility model: this utility model adsorbs sexual cell by suction pipe is carried out evacuation, then seals
After suction pipe, preservation carrier is sunk to liquid nitrogen and carry out freezen protective.This utility model has carried out totally-enclosed preservation to sample, prevents sample
Product contact with liquid nitrogen, it is to avoid the potential threat that sample is contaminated.
This utility model is after sinking to liquid nitrogen, and due to the effect of expanding with heat and contract with cold of metal derby, volume reduces, can increase further
Vacuum in suction pipe, makes sexual cell be adsorbed in the aspiration port of suction pipe reliably, reduces freezing oocyte and embryo
Loss probability.In addition the heat conductivility of metal derby, contributes to the quick freezing of Seal and preservation sample, reduces the freezing damage of sample
Wound.And, the structure of this utility model preservation carrier arranges and facilitates operator more quickly to take out cell from liquid nitrogen, improves
Freezen protective efficiency.
Ring cylinder threadedly realizes being tightly connected with sealing lid, and connected mode is simply effective, connects reliable for effect, also
It is prevented from connection procedure the vibration effect that sexual cell is caused, efficiently solves and prior art easily causes cell lose
The problem lost.This utility model has simple in construction, the convenient advantage being suitable for, and is a kind of preferably biological material vitrified frozen
Preserve carrying tool.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vitrificated cryopreserration carrier of oocyte described in the utility model and embryo.
Detailed description of the invention
Detailed description of the invention one: present embodiment is described below in conjunction with Fig. 1, oocyte and embryo described in present embodiment
Vitrificated cryopreserration carrier, it include suction pipe 1, top plug 2 and seal lid 3,
Top plug 2 is tightly connected the upper port of suction pipe 1, and the bottom of suction pipe 1 is needle-like,
It is provided with the ring cylinder 1-1 of band cavity on the lateral wall of the upper semisection of suction pipe 1, in ring cylinder 1-1, metal derby 1-2 is set,
Suction pipe 1 inner chamber is communicated by the passage 1-3 on suction pipe 1 sidewall with ring cylinder 1-1 cavity；
Sealing and be threaded connection between lid 3 and ring cylinder 1-1, suction pipe 1 bottom is positioned at sealing lid 3.
In present embodiment, suction pipe 1, top plug 2 and sealing lid 3 define a carrier tool being tightly connected, ring cylinder 1-1
Setting holding position when can move as carrier；When metal derby 1-2 volume-diminished at low temperatures, the thin sky in suction pipe
Gas can be circulated by passage, thus contributes to the air-flow equilibrium in suction pipe, and the adsorption effect making sexual cell is more preferable.
Detailed description of the invention two: embodiment one is described further by present embodiment, described metal derby 1-2 is aluminium block
Or Al alloy block.
The thermal linear expansion coefficient of aluminum metal is relatively big, which dictates that its effect expanded with heat and contract with cold becomes apparent from, thus effectively
Reduce the pressure in suction pipe.
