Description
Technical field
This utility model belongs to biological frozen field, particularly relates to a kind of double-deck cryoprotection support.
Background technology
Biomaterial freezing method commonplace in biological frozen field is vitrification quick freezing, the sperm that chilled protective agent is processed or other biological material be placed in load bar in, then loads bar is placed in freezing support in and be placed in liquid nitrogen container preservation.At present conventional freezing support is made up of the plastic bushing that aluminium brackets and two internal diameters up and down of being placed in aluminium brackets are equal, two plastic bushings are one end open one end enclosed construction and opening docking, it is placed or taken out carrying bar by plastic bushing movement in aluminium brackets, the freezing support Existential Space utilization rate of this structure is the highest, a biological sample is placed in one freezing support, and in use cause support easily to float due to the exuberant air of upper inside pipe casing, affect refrigerating effect.
Summary of the invention
The purpose of this utility model is to provide a kind of double-deck cryoprotection support, can improve the space availability ratio of freezing support, overcome the shortcoming that existing support easily floats.The purpose of this utility model is achieved through the following technical solutions:
A kind of double-deck cryoprotection support; including lid, upper sleeve pipe and setting of casing; described lid, upper sleeve pipe and setting of casing all include blind end and opening; the opening of described lid is socketed in the opening of sleeve pipe; the blind end of described upper sleeve pipe down extends and is provided with the elongated end being socketed in setting of casing opening, and the sidewall of the opening of described lid and the elongated end of upper sleeve pipe the most all offers wide seam.
Preferably, between described lid and upper sleeve pipe, the socket between upper sleeve pipe and setting of casing is interference fits.
Preferably, the inwall of described upper sleeve pipe is provided with and limits the annular protrusion thing that moves down of described lid, and described cased inwall has been provided with what the described upper sleeve pipe of restriction moved down annular protrusion thing.
Preferably, the opening port outer wall of described lid is provided with bulge, and the opening port inner wall of described upper sleeve pipe is provided with annular protrusion thing, can prevent lid from skidding off sleeve pipe easily during use.
Preferably, the elongated end port outer wall of described upper sleeve pipe is provided with bulge, and described cased opening port inner wall is provided with annular protrusion thing, can prevent sleeve pipe from skidding off setting of casing easily during use.
Further, described bulge is one section of continuous print arc-shaped convex or the some projections arranged at equal intervals.Preferably, the side wall upper part of described lid and upper sleeve pipe is offered porose, tweezers can be used to insert in the hole and stir lid or upper sleeve pipe.
Preferably, also including the metallic sheath being connected with described setting of casing, the effect of described metallic sheath is to prevent described protective cradle to float further.
The beneficial effects of the utility model are: provide a kind of double-deck cryoprotection support, including upper and lower sleeve pipe, can place the load bar being loaded with biomaterial respectively, improve space availability ratio；Described lid opening and described on the sidewall of elongated end of sleeve pipe the most all offer wide seam, it is not necessary to described lid is taken off from upper sleeve pipe, takes off from setting of casing without by described upper sleeve pipe, just may pass through wide seam and put into load bar, facilitate use；And upper and lower sleeve pipe all fills liquid nitrogen during using, support is difficult to float；Fixing a metallic sheath at described lower pipe box, can prevent protective cradle from floating further, on the other hand relatively prior art saves material, reduces cost.

A-quadrant enlarged drawing in Fig. 2 embodiment；
The wide crack structure schematic diagram of the elongated end of the opening of lid and upper sleeve pipe in Fig. 3 embodiment.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
As shown in Figure 1; a kind of double-deck cryoprotection support includes lid 1, upper sleeve pipe 2, setting of casing 3 and the metallic sheath 4 being socketed successively; described lid 1, upper sleeve pipe 2 and setting of casing 3 all include that blind end and opening, the opening 11 of described lid 1 stretch in the opening of sleeve pipe 2；Described upper sleeve pipe 2 is down extended with elongated end 22 from blind end 21, and described elongated end 22 stretches in the opening of setting of casing 3.Connection between described lid 1 and described upper sleeve pipe 2 and between described upper sleeve pipe 2 and described setting of casing 3 should be interference fits, in order to described lid 1 or described upper sleeve pipe 2 can stop by any point in moving process.
As it is shown on figure 3, the sidewall of the elongated end 22 of the opening sidewall of described lid 1 and described upper sleeve pipe 2 the most all offers wide seam.During use, it is not necessary to described lid pipe 1 is taken off, only need to will move on described lid pipe 1, just the load bar being loaded with biomaterial can be placed in described upper sleeve pipe 2 through described wide seam, and carrying bar placement in setting of casing 3 is also in like manner.Facilitate the carrying out of refrigeration operation.
On described, the inwall of sleeve pipe 2 upper inside wall and opening end is respectively provided with annular protrusion, the outer wall of the opening end of described lid 1 arranges bulge, lid 1 is limited and moves within a certain height, can prevent described lid 1 from excessively going deep into, inconvenience is taken out from described upper sleeve pipe 2, and preventing lid 1 from deviating from upper sleeve pipe 2 easily, concrete structure is as shown in Figure 2.
Similarly, inwall in described setting of casing 3 upper inside wall and opening end is respectively provided with annular protrusion, the outer wall of elongated end 22 end of described upper sleeve pipe 2 arranges bulge, upper sleeve pipe 2 is limited and moves within a certain height, described elongated end 22 can be prevented the most deep, and preventing described upper sleeve pipe 2 from deviating from from setting of casing 3 easily, concrete structure is as shown in Figure 2.
Above-mentioned bulge can be a continuous print arc-shaped convex, it is also possible to be the some projections arranged at equal intervals, as long as not affecting its position-limiting action played.
During use, freezing for bilayer support is dipped in liquid nitrogen, exposes wide seam by moving in lid 1, and full liquid nitrogen in making sleeve pipe 2；Similarly, full liquid nitrogen in wide seam, and use setting of casing 3 are exposed in shifting on upper sleeve pipe 2；The sperm processed by chilled protective agent in liquid nitrogen or other biological material are placed in load bar, are respectively placed in upper and lower sleeve pipe through width seam by two load bars, and the label for label biological materials then can be affixed on the sidewall of lid or sleeve pipe.
In one embodiment, it is also possible to respectively described lid 1 upper portion side wall and on the upper portion side wall of sleeve pipe 2 offer hole 5, in order to use tweezers to insert in hole 5 and stir lid 1 or upper sleeve pipe 2.
In one embodiment, described setting of casing 3 blind end is also socketed with metallic sheath 4, closely cooperates between setting of casing 3 and metallic sheath 4, under the action of gravity of metallic sheath 4, prevents cryoprotection support from floating, affects refrigerating effect.
Above-described embodiment is explanation rather than the restriction of design novel to this use, also should be regarded as the equivalent of the technical characteristic that above-described embodiment is made within protection domain of the present utility model.
