Description
Technical field
The utility model relates to a kind of freezing bracket, in particular to a kind of novel embryo/egg freezing bracket.
Background technique
Vitrifying fast freezing is to fuse high concentration cryoprotector and embryo/ovum, after certain time balances, embryo
Tire/ovum volume reduces 30-50% because of dehydration, and dehydration embryo/ovum merging freezing is carried in bar, then will be loaded with de- later
The freezing of water embryo/ovum, which carries bar and direct plunges into liquid nitrogen, to be made to be dehydrated cell instantaneous vitrification, forms lower preservation in no ice crystal,
Injury to cell is caused to reduce intracellular ice.
The freezing load bar that load dehydration cell will not be damaged in refrigerating process in order to protect, and be easy from liquid
Embryo/ovum patient information can also be told simultaneously by taking out in nitrogen tank, it will usually sample is placed in freezing casing, it is cold
Freeze casing to be clamped in special freezing bracket, then is freezed combining the bracket of freezing casing to be placed in liquid nitrogen container.
Presently used freezing bracket is to facilitate sandwiching and taking out for casing, simultaneously with the aluminium bracket of semicircle button
It can complete to load and shift embryo/ovum function in -196 DEG C of liquid nitrogen.The freezing bracket and freezing set of this form
Pipe there are the problem of are as follows: (1) be not the annular of closure since freezing support Design is semicircle, it is anti-in the well-bucket of liquid nitrogen container
It takes out/is put into again, with other bracket phase mutual friction, often will cause the loss of casing, embryo/ovum of required patient can not be found
Son.(2) although sample can be fixed therein well by two freezing casings used in existing freezing equipment, sample is not
Easily skid off freezing casing, still, freezing casing be plastic tube structure, two docking freezing casing entering part liquid nitrogen it is same
The air that Shi Yiqi enters cannot be discharged in time, and the freezing casing put into liquid nitrogen container can be due to internal exuberant air
Liquid nitrogen surface is swum in again, and the environment temperature of sample can change during floating repeatedly in this way, influence sample freezing
The quality of preservation.In routine work, bracket and casing are snarled with adhesive tape sometimes, but adhesive tape can fail at low temperature, still
Casing can be lost, can not be solved the above problems.
Summary of the invention
Technical problem to be solved by the utility model is: providing a kind of novel embryo/egg freezing bracket, the freezing bracket
It is that the function of existing bracket and casing is combined as a whole, it is easy to be lost and easily floated by air impact solves prior art middle sleeve
The problem of floating to liquid nitrogen surface can guarantee the quality of sample freezing.
The technical solution for solving above-mentioned technical problem is: a kind of novel embryo/egg freezing bracket, including bottom is netted deposits
Put pipe, mark connection aluminium flake, the netted fixing pipe in top and handling section, the netted storage pipe in bottom be by metal wire knitted at
Sealed bottom, open-topped netted pipe structure, the netted fixing pipe in top be by metal wire knitted at top and bottom end
The bottom end of the netted pipe structure being open, mark connection aluminium flake is fixedly connected on the netted storage pipe in bottom, mark connection aluminium flake
Top be fixedly connected with the netted fixing pipe bottom end in top, the netted fixing pipe top in top is fixedly connected with handling section.
Novel embryo/egg freezing bracket total length is 11-13cm, and the length of the netted storage pipe in bottom is 5-7cm,
The length of the netted fixing pipe in top is 2-4cm.
The handling section is the aluminium sheet structure with bending structure.
Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
1, it is mounted with embryo/ovum load bar to be located in the netted storage pipe in bottom of the utility model, carries the upper of bar
Portion is located in the netted fixing pipe in top, due to the netted fixing pipe in top be by metal wire knitted at netted pipe structure, can be with hand
The dynamic top opening for mediating the netted fixing pipe in top, being reduced prevents to carry bar from skidding off.The bottom of the utility model is netted to deposit
It puts the netted fixing pipe of pipe and top to be fixedly connected with mark connection aluminium flake, handling section, i.e., by the function of existing bracket and casing
It can be combined as a whole, even if taking out/being put into repeatedly in the well-bucket of liquid nitrogen container, the netted storage pipe in bottom and the netted fixing pipe in top
Loss will not be slipped, more secure and reliable is used.
2, the bottom of the utility model it is netted storage pipe and the netted fixing pipe in top be by metal wire knitted at it is netted
Pipe structure, during liquid nitrogen, air can be discharged from the gap between netted, be not in because of its internal exuberant sky
Gas and the case where swim in liquid nitrogen surface, can effectively avoid because of the phenomenon that bringing variation of ambient temperature of floating repeatedly, Neng Goubao
Demonstrate,prove the quality of sample freezing.
In the following, making in conjunction with the accompanying drawings and embodiments to novel embryo/egg freezing bracket technical characteristic of the utility model
Further instruction.
Detailed description of the invention
Fig. 1: the novel embryo of the utility model/egg freezing bracket perspective view.
Fig. 2: the novel embryo of the utility model/egg freezing bracket left view.
Fig. 3: Fig. 2 A-A cross-sectional view.
In figure: the netted storage pipe in the bottom 1-, 2- mark connection aluminium flake, the netted fixing pipe in the top 3-, 4- handling section.
Specific embodiment
Embodiment 1: a kind of novel embryo/egg freezing bracket, as shown in Figure 1-Figure 3, including the netted storage pipe 1 in bottom,
Mark connection aluminium flake 2, the netted fixing pipe 3 in top and handling section 4, the netted storage pipe in bottom be by metal wire knitted at bottom
Portion sealing, open-topped netted pipe structure, the netted fixing pipe in top be by metal wire knitted at top and bottom end it is equal
The bottom end of the netted pipe structure of opening, mark connection aluminium flake is fixedly connected on the netted storage pipe in bottom, mark connection aluminium flake
Top is fixedly connected with the netted fixing pipe bottom end in top, and the netted fixing pipe top in top is fixedly connected with handling section.The phase of patient
Closing information (patient's name, date, embryo/ovum number, rank etc.) can identify on mark connection aluminium flake 2.
In the present embodiment, novel embryo/egg freezing bracket total length is 11-13cm, preferably 12cm, and bottom is netted to deposit
The length for putting pipe 1 is 5-7cm, and preferably 6cm, the length of the netted fixing pipe 3 in top is 2-4cm, preferably 3cm.As a kind of transformation,
Length, the length of the netted fixing pipe 3 in top of the novel embryo/total length of egg freezing bracket, the netted storage pipe 1 in bottom
Variation can also be adjusted according to the actual situation.
In the present embodiment, the handling section 4 is the aluminium sheet structure with bending structure.It is described hand-held as a kind of transformation
The specific structure of section can also change according to actual needs.
Refrigerating process: will be mounted with embryo/ovum load bar and be located in the netted storage pipe in bottom of the utility model,
The top for carrying bar is located in upper wire shape fixing pipe, mediates the top opening of the netted fixing pipe in top manually, being reduced makes to carry
Bar cannot skid off, due to the netted fixing pipe in top be by metal wire knitted at netted pipe structure, have shrinkage, manually can
Control the size of its opening；Finally the utility model is placed into -196 DEG C of liquid nitrogen and is freezed.
