Preservation device for accurately selecting frozen embryos for embryo freezing technology

Abstract

The invention discloses a storage device for accurately selecting frozen embryos for embryo freezing technology, which comprises a freezing tank, a cover plate rotatably arranged on the freezing tank, a handle for rotating the cover plate, and a handle rotatably arranged on the freezing tank. The sleeve on the cover, the pull rod rotatably arranged on the sleeve, the first support rod symmetrically arranged on the cover, and the freezing bracket arranged on the first support rod; The freezing support includes a support ring, a second support rod symmetrically arranged on the support ring, fastening grooves respectively arranged on the second support rods, and parallel grooves arranged between the first V-shaped guide rods , the second freezing tube arranged on the parallel groove. In the present invention, by adding a pull rod to the cryogenic tube, the required frozen embryos can be precisely selected without opening the frozen tube, so that other embryos will not be exposed to normal temperature and the quality of the embryos can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of frozen embryos, in particular to a storage device for accurately selecting frozen embryos for the embryo freezing technology. Background technique [0002] The existing embryo storage is frozen through freezing jars. Each freezing jar can store multiple embryos. Since each embryo is different, it is necessary to open the freezing jar to hold multiple embryos. The frozen racks are taken out for selection, but only one or two need to be taken each time for selection and thawing, which is a waste of time during selection, and because each embryo is exposed to normal temperature, it will affect the activity of the rest of the embryos. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a storage device for precisely selecting frozen embryos for embryo freezing technology. [0004] In order to achieve the above object, the present inventi...

[0002] The existing embryo storage is frozen through freezing jars. Each freezing jar can store multiple embryos. Since each embryo is different, it is necessary to open the freezing jar to hold multiple embryos. Take out the frozen racks for selection, but you only need to take one or two each time you select and thaw, which is a waste of time during selection, and because each embryo is exposed to normal temperature, it will affect the activity of the rest of the embryos.
