Abstract
The utility model relates to a kind of gamete and embryo's the closed freezing carrier of supper-fast cooling, comprise outer tube, one end of outer tube is heat-sealing closed end, other end connection metal base, metab is the container of cylindrical upper end opening, metab upper end open and outer tube lower end match and link together, inner tube is housed in outer tube, gamete or embryo are housed in inner tube, inner tube lower end is flattened and is " one " font and wire netting is housed, wire netting and metab inner chamber match, inner tube lower end packs in metab, and the grid of wire netting is 150 order/inches.The utility model has the advantage of, overcome the potential safety hazard of existing open freezing carrier and the shortcoming that sequencing refrigeration operation is numerous and diverse, rate of temperature fall is low, this design can not only avoid the cross pollution causing of open freezing carrier and liquid nitrogen to pollute, and can significantly improve closed freezing carrier rate of temperature fall, the flow process that simplifies the operation, reduces operating cost.
Description
Technical field
The utility model belongs to gamete and embryo cryopreservation equipment technical field, particularly relates to a kind of gamete and embryo's the closed freezing carrier of supper-fast cooling.
Background technology
At present, most animals research laboratory and human ancillary reproductive center laboratory are all used open freezing carrier to complete gamete and embryo's freezing preservation, this is because open freezing carrier can make solution directly contact liquid nitrogen, reach fast cooling, contribute to the formation of vitrifying state, reduce ice crystal injury.But, there is unsafe factor in open freezing carrier like this, especially, for human reproduction center, embryo's safety is extremely important, may there is the cross pollution between embryo, or pollute because liquid nitrogen pollutes the embryo who causes, therefore, closed freezing carrier uses particularly necessary, but existing closed freezing or complete by sequencing frigorimeter, or tubule method is freezing, be all by air mediation cooling, so rate of temperature fall is significantly lower than open carrier after tubule sealing.In addition, sequencing frigorimeter not only operating process is more loaded down with trivial details, and has increased reproductive center operating cost, be difficult to promote, and tubule method is freezing more because of its loading liquid, affect rate of temperature fall, so Freezing-thawing effect is undesirable, therefore, need a kind of novel applicable gamete and embryo's closed freezing carrier, not only safe, and can improve rate of temperature fall, simplify the operation course, reduce operating cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of gamete and embryo's the closed freezing carrier of supper-fast cooling, this design can not only avoid the cross pollution causing of open freezing carrier and liquid nitrogen to pollute, and can significantly improve closed freezing carrier rate of temperature fall, the flow process that simplifies the operation, reduces operating cost.
The utility model solves the technical scheme that its technical problem adopts: a kind of gamete and embryo's the closed freezing carrier of supper-fast cooling, comprise outer tube, one end of described outer tube is heat-sealing closed end, other end connection metal base, described metab is the container of cylindrical upper end opening, described metab upper end open and outer tube lower end match and link together, in described outer tube, inner tube is housed, gamete or embryo are housed in described inner tube, described inner tube lower end is flattened and is " one " font and wire netting is housed, described wire netting and metab inner chamber match, described inner tube lower end packs in metab.
The grid of described wire netting is 150 order/inches.
Described wire netting is made with copper or stainless steel material.
Beneficial effect
The utility model has the advantage of, overcome existing open freezing carrier potential safety hazard and the shortcoming that sequencing refrigeration operation is numerous and diverse, rate of temperature fall is low, this design can not only avoid the cross pollution causing of open freezing carrier and liquid nitrogen to pollute, and can significantly improve closed freezing carrier rate of temperature fall, the flow process that simplifies the operation, reduces operating cost.Enough avoid the potential safety hazard producing because of " open ", simplify the operation, reduce costs, and can improve the rate of temperature fall that greatly improves closed freezing carrier.

Fig. 2 is the structural representation of the new outer tube of this practicality.
Fig. 3 is the structural representation of the new inner tube of this practicality.
Fig. 4 is that this practicality is newly held pipe device and inserted state diagram when inner tube.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figures 1 to 4, a kind of gamete and embryo's the closed freezing carrier of supper-fast cooling, comprise outer tube 1, one end of described outer tube 1 is heat-sealing closed end 5, other end connection metal base 2, described metab 2 is containers of cylindrical upper end opening, described metab 2 upper end open and outer tube 1 lower end match and link together, in described outer tube 1, inner tube 3 is housed, in described inner tube 3, gamete or embryo are housed, described inner tube 3 lower ends are flattened and are " one " font and wire netting 4 is housed, described wire netting 4 matches with metab 2 inner chambers, described inner tube 3 lower ends pack in metab 2.
The grid of described wire netting 4 is 150 order/inches.
Described wire netting 4 use copper or stainless steel material are made.
In actual use, the inner tube 3 that first gamete or embryo are housed is inserted in outer tube 1, and the wire netting 4 of inner tube lower end fills metab 2, due to Action of Gravity Field, and both close contacts.When carrier entirety immerses after liquid nitrogen, the solution in metal bottom 2, wire netting 4 and inner tube 3 forms a quick conductive system, has greatly improved the rate of temperature fall of inner tube 3 interior solution.While thawing, first with scissors, outer tube 1 upper end heat-sealing closed end 5 is cut off, because inner tube lower end is " one " font, will be held pipe device 6 and insert inner tube upper end and play a supporting role, the protection interior gamete of inner tube 3 or embryo are injury-free, then take out rapidly, thaw.
