Abstract
The utility model aims at providing an embryo vitrification freezing carrier capable of reducing freezing liquid accumulated around an embryo, so as to improve the cooling speed of the embryo and the freezing effect. The embryo vitrification freezing carrier comprises a carrier rod and a sheet which is arranged at the end part of the carrier rod. One pit or a plurality of pits is(are) arranged at the top surface of the sheet. When the embryo vitrification freezing carrier is used, the embryo which is treated by using the vitrification freezing liquid is rapidly contained in the pit on the sheet of the carrier, excessive freezing liquid on the surface of the sheet of the carrier is rapidly absorbed away, then the carrier is sheathed in a pre-cooled casing and the casing is put in a liquid nitrogen tank for long-term preservation. Therefore, the volume of the freezing liquid accumulated around the embryo is reduced, the cooling speed is improved and the freezing effect is improved.
Description
Technical field
The utility model belongs to technical field of medical instruments, specially refers to a kind of embryo vitrifying freeze carrier.
Background technology
Present embryo vitrifying freeze method is that the embryo after handling through glass freezing liquid is contained on the thin slice; Again thin slice is dropped into tubulature in the liquid nitrogen rapidly, its weak point is that to be stained with the freezing liquid of band on the thin slice more, and difficult suction is gone; Therefore low to embryo's rate of temperature fall, refrigerating effect is relatively poor.
The utility model content
The purpose of the utility model is to propose a kind ofly can to reduce the embryo vitrifying freeze carrier that embryo's periphery accumulates freezing liquid, to improve embryo's rate of temperature fall, improves refrigerating effect.
The embryo vitrifying freeze carrier of the utility model comprises the thin slice that carries bar and be arranged at year boom end, and key is that said thin slice end face is provided with one or more pits.
In use, the embryo after will passing through glass freezing liquid and handling is contained in the pit of carrier sheet end face fast, and rapidly that carrier sheet surface is unnecessary freezing liquid inhales and go, and then carrier is inserted in the good sleeve pipe of precooling, puts into that liquid nitrogen container is medium-term and long-term to be preserved.So just reduce the freezing liquid volume that embryo's periphery accumulates, improved rate of temperature fall, improved refrigerating effect.
Further; The cross section of said thin slice is the thin triangle in thick middle both sides; Said pit is positioned at leg-of-mutton top, and the freezing liquid around the pit will flow down thin slice from the inclined-plane along thin slice rapidly like this, and can not accumulate in around the pit; Further improve rate of temperature fall, improved refrigerating effect.In like manner, can also be provided with like this: said thin slice end face is provided with one or more convexities, and said pit is positioned at protruding top.
The embryo vitrifying freeze carrier structure of the utility model is simple, and cost is low, and is easily manufactured, can effectively reduce embryo's periphery and accumulate freezing liquid, improves embryo's rate of temperature fall, improves refrigerating effect, has good practicability.

Fig. 1 is the vertical view of the embryo vitrifying freeze carrier of the utility model.
Fig. 2 is the whole cutaway view of the embryo vitrifying freeze carrier of the utility model.
Fig. 3 is the cutaway view of thin slice in the embryo vitrifying freeze carrier of the utility model.
Embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
Like Fig. 1, shown in 2, the embryo vitrifying freeze carrier of present embodiment comprises the thin slice 2 that carries bar 1 and be arranged at year bar 1 end, and thin slice 2 end faces are provided with three pits 3.
In use, the embryo that will pass through after glass freezing liquid is handled is contained in the pit 3 on the carrier sheet fast, and the unnecessary freezing liquid in carrier sheet 2 surfaces is inhaled gone rapidly, then carrier is inserted in the good sleeve pipe of precooling, puts into the liquid nitrogen container midium or long term and preserves.So just reduce the freezing liquid volume that embryo's periphery accumulates, improved rate of temperature fall, improved refrigerating effect.
As shown in Figure 3, the cross section of thin slice 2 is the thin triangle in thick middle both sides, and pit 3 is positioned at leg-of-mutton top; Freezing liquid around the pit 3 will flow down thin slice 2 from the inclined-plane along thin slice 2 rapidly like this; And can not accumulate in around the pit 3, further improved rate of temperature fall, improved refrigerating effect.
Claims (3)
1. an embryo vitrifying freeze carrier comprises and carries bar and be arranged at the thin slice that carries boom end, it is characterized in that said thin slice end face is provided with one or more pits.
2. embryo vitrifying freeze carrier according to claim 1 is characterized in that the cross section of said thin slice is the thin triangle in thick middle both sides, and said pit is positioned at leg-of-mutton top.
