Description
Technical Field
The invention belongs to the technical field of frozen embryos, and particularly relates to a storage device for accurately selecting frozen embryos for an embryo freezing technology.
Background
Current embryo is cold-stored and is frozen through freezing jar, and every freezing jar can refrigerate a plurality of embryos, because every embryo all is different, when taking, need open freezing jar, will contain the freezing support of a plurality of embryos and take out and select, but only need take one two when selecting to unfreeze at every turn, both wasted time when selecting, again because each embryo exposes in the normal atmospheric temperature, influences the activity of all the other embryos.
Disclosure of Invention
The invention provides a preservation device for accurately selecting frozen embryos, which aims to overcome the defects of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides an embryo freezing technique is with save set of freezing embryo of accurate selection, includes freezing jar, rotationally locates apron on the freezing jar, the handle that is used for rotating the apron, rotationally locate sleeve on the apron, rotationally locate pull pole, symmetry on the sleeve are located first bracing piece on the apron, are located freezing support on the first bracing piece.
Just at first, through the handle, open the apron, then pour freezing the inside into with freezing support, carry out the freezing to the embryo, when wanting to take out the embryo in freezing support, as long as rotate sleeve or pull pole for required one of them embryo is put on the pull pole, then pulling pull pole, just can be accurate extract required embryo, thereby realize need not pouring under the condition of opening in freezing, can accurately select the freezing embryo that needs, make other embryos can not expose in the normal atmospheric temperature, guarantee embryo quality.
Freezing support includes support ring, symmetry and locates second bracing piece on the support ring, locates respectively tight catching groove on the second bracing piece, edge a plurality of first V type guide bars that support ring circumference distributes, locate respectively arc spacing groove on the first V type guide bar, locate a plurality of first cryovials on the arc spacing groove, edge support ring circumference distributes and be used for right a plurality of second V type guide bars of first cryovial direction, locate parallel groove between the first V type guide bar, locate second cryovial on the parallel groove.
The first V-shaped guide rod is mainly used for supporting the first freezing pipe and the second freezing pipe, wherein the first freezing pipe is arranged in the first V-shaped guide rod and is clamped by the V-shaped limiting groove and the arc-shaped limiting groove, and when the first freezing pipe is pushed, the first freezing pipe can fall from the first V-shaped guide rod and enter the second V-shaped guide rod; the second V-shaped guide rod is used for limiting and guiding the first freezing pipe, and when the first freezing pipe falls from the first V-shaped guide rod, the second V-shaped freezing pipe can support the first freezing pipe; the second freezer pipe is on the parallel groove between two first V type freezer pipes, the second freezer pipe can slide on the parallel groove, the arc spacing groove can be slightly spacing to first freezer pipe and second freezer pipe, prevent that first freezer pipe and second freezer pipe from sliding automatically under the condition that does not have other effort, thereby improve stability, accurate the selecting provides the prerequisite afterwards, thereby make one of them freezer pipe when being taken out, can not influence other freezer pipes, make other freezer pipes can not expose in the normal atmospheric temperature, guarantee the freezing quality to the embryo.
The pull rod further comprises a grab handle arranged on the pull rod, a placement groove arranged on the pull rod, a first fixed rod arranged on the pull rod, a first selecting rod rotatably arranged on the first fixed rod, and a first unlocking assembly arranged on the grab handle; the second freezing pipe can enter the placing groove; the first selecting rod can push the second freezing pipe to enter the placing groove, and a torsion spring is arranged between the first selecting rod and the first fixing rod.
The first freezing pipe and the second freezing pipe can be taken out by the drawing rod, but the second freezing pipe is mainly selected when the drawing rod rotates, the first selecting rod correspondingly rotates when the drawing rod rotates, the surface of the cover plate is marked, so that the first selecting rod can accurately rotate to the second freezing pipe to be taken without opening the cover plate, then the first unlocking assembly is unlocked, the drawing rod can be pushed to move downwards, the first selecting rod can move downwards, as the first selecting rod is obliquely arranged downwards, the second freezing pipe can be pushed by the selecting rod when the first selecting rod moves downwards, the second freezing pipe moves inwards to enter the placing groove, then the drawing rod is pulled out, the second freezing pipe is also taken out together with the drawing rod, and the required freezing pipe can be accurately selected, so that other embryos can not be exposed at normal temperature, and the quality of the embryos is ensured.
