Problems solved by technology

However, the existing embryo and egg freezing device has a single structure, mainly including a storage box and a box cover. Liquid nitrogen is stored inside the storage box, and the treated embryo holding vessel is put into the storage box and the box cover is closed. When using this device for storage, there are many disadvantages: the structure of the storage box is relatively simple, which may easily lead to changes in the internal temperature of the st

Abstract

The embodiment of the invention relates to the technical field of assisted reproduction, and particularly discloses an embryo and ovum freezing device in assisted reproduction technology, which comprises a shell, the shell is provided with a placing cavity, and a storage box is fixedly arranged in the placing cavity; a protective cover plate is rotatably arranged at a top opening of the placing cavity, and the free end of the protective cover plate is fixedly connected with the shell through a safety lock assembly; a rotating cylinder and a rotating shaft are coaxially and rotationally arranged in the storage box, and the top end of the rotating cylinder is coaxially and fixedly connected with the bottom end of the rotating shaft; an operation assembly linked with the rotating cylinder isarranged at the bottom of the shell; a plurality of partition plates are evenly distributed and fixedly arranged on the outer ring of the rotating shaft, and a storage cavity is formed between every two adjacent partition plates. According to the device, storage tanks in one target storage cavity can be convenient for taking and placing, and the freezing effect on embryos and ova in one non-targetstorage cavity is guaranteed; and a safety lock assembly is arranged, so that the safety is enhanced.

Description

technical field [0001] The embodiment of the present invention relates to the field of assisted reproductive technology, in particular to a freezing device for embryos and eggs in assisted reproductive technology. Background technique [0002] As we all know, embryo cryopreservation technology mainly refers to a technology in which selected embryos with good quality are subjected to special protection measures and cooling procedures, so that they can stop their metabolism and be preserved under low temperature conditions. After being able to restore metabolism and activity, embryos are usually kept in liquid nitrogen. [0003] In the clinical treatment of infertility in assisted reproductive medicine, it is necessary to cryopreserve the embryos of IVF patients for later thawing and transferring the embryos back to the uterus for conception. The specific operation of embryo freezing needs to be completed with the help of containers, and the commonly used containers include e...
