Description
Technical field
The present invention relates to tissue stored frozen fields, are specifically related to a kind of tissue storage device for liquid nitrogen frozen.
Background technique
In the reproductive medicine section of various big hospital, often used liquid nitrogen container comes to sperm, embryo or the ovum to people
Carry out vital preservation.In stored frozen, usually first sperm, embryo or ovum are deposited in freezer storage pipe, then again
By liquid nitrogen pour into in freezer storage pipe with to sperm, embryo or egg freezing, it is finally that the freezer storage pipe of liquid filling nitrogen is direct
It is placed in liquid nitrogen container in carrying out and maintains extremely low temperature, to realize vital preservation.Freezer storage pipe, which is placed directly in liquid nitrogen container, to be existed
Following problems:
1, freezer storage pipe, which is placed directly in liquid nitrogen container, to swim on liquid nitrogen, cause freezer storage pipe complete with liquid nitrogen
Full connected, this makes sperm, embryo or ovum in freezer storage pipe there is a possibility that inactivation.
2, freezer storage canal float is on liquid nitrogen, and when carrying out liquid nitrogen supplement, liquid nitrogen can wash away freezer storage pipe, cause cold
It freezes the label being sticked on storage tube wall to be easy to fall off, so as to cause sperm, embryo or the ovum that can not recognize freezer storage pipe
Ownership.
3, due to that can store many freezer storage pipes in liquid nitrogen container, by special tool tong by freezer storage pipe when taking-up
Go out from liquid nitrogen container inner clip, but clamping when, the label being sticked on freezer storage tube wall is difficult to distinguish, therefore clamps often
Non-targeted object can often be taken out, it is also possible to will affect the activity of sperm in freezer storage pipe, embryo or ovum.
