Abstract

The invention discloses an embryo automatic liquid change culture dish including at least one group of culture unit; the culture unit includes a liquid injection pool, a culture pool and a waste liquid chamber which communicate with each other in turn; the upper part of the liquid injection pool communicates with a liquid inlet channel, and the bottom of the liquid injection pool communicates withthe bottom of the culture pool through an overflow channel; the bottom of the culture pool is provided with at least one embryo micropore, and the bottom of the embryo micropore communicates with thewaste liquid cavity through a waste liquid flow channel. The embryo automatic liquid change culture dish can realize complete liquid exchange and effectively meet material requirements required in each development stage of an embryo; through automatic liquid exchange, the damage of repeated manual intervention operation to an embryo culture environment and the damage of the embryo are avoided, the stability of the embryo culture and the quality of a blastocyst can be improved, and the clinical pregnancy rate and the live yield are effectively increased.

Description

technical field [0001] The invention relates to the field of cell culture, in particular to an embryo automatic fluid exchange culture dish. Background technique [0002] Maintaining a suitable and stable environment for the embryo culture system is one of the key factors affecting the outcome of in vitro fertilization-embryo transfer (IVF-ET). Embryo culture fluid is an essential and important substance in the process of doing test-tube babies. In the stage of fertilization, the sperm and eggs are combined in vitro to form fertilized eggs, and then the fertilized eggs are placed in the culture medium for cultivation, which can simulate the uterine environment and make the embryos grow and develop well. Embryo culture medium not only plays an important role in embryo development, but also has a certain influence on the development of offspring after embryo implantation. It has become one of the hot spots of attention and research in the field of assisted reproductive techno...
