Problems solved by technology

Since all sperm can directly contact the egg, the chance of fertilizing the egg with weak, poor quality, and even deformed sperm is greatly increased, which is not conducive to the formation of high-quality embryos and affects the clinical pregnancy rate.

Embodiment Construction

[0026] Such as Figure 1 to Figure 5 As shown, the present invention is a fertilization dish, including two specifications of a four-hole dish and an annular dish, and each specification includes a dish body and a dish cover. The dish body includes a bottom wall 3, a main side wall 4 and a secondary side wall 5, the three parts are integrally formed, the main side wall 4 and the secondary side wall 5 are arranged on the bottom wall 3, and the secondary side wall 5 is located on the main side wall 4 inside. In the four-hole dish, the four inner corners of the secondary side wall 5 are respectively provided with holes 1 . In the annular dish, an intermediate hole 13 is provided in the middle of the secondary side wall 5 .

[0027] (1) Features of the improved four-hole dish:

[0028] 1. If figure 1 As shown, there is a cross-shaped groove 2 between the four holes 1 of the ordinary four-hole culture dish, which communicates with the four holes 1. The diameter of the arc at th...

Abstract

The invention relates to the technical field of human assisted reproduction, in particular to a novel culture dish used for fertilization. The culture medium is a four-hole dish or an annular dish; a dish body of the culture dish comprises a bottom wall, a main side wall and an auxiliary side wall which are integrally formed; the main side wall and the auxiliary side wall are arranged on the bottom wall; the auxiliary side wall is positioned on an inner side of the main side wall; in the four-hole dish, a hole is formed in each of four corners on an inner side of the auxiliary side wall; in the annular dish, a middle hole is formed in the middle of the auxiliary side wall. Sperms added during fertilization are separated from an ovum by utilizing a bionic principle and good-quality sperms are enabled to swim to the periphery of the ovum for fertilization by utilizing a groove, so that the good-quality embryo rate and the clinical pregnancy rate of in-vitro fertilization can be increased.

Description

technical field [0001] The invention relates to the technical field of human assisted reproduction, in particular to a petri dish for fertilization. Background technique [0002] At present, there are two specifications of petri dishes for in vitro fertilization in assisted reproduction laboratories: four-hole dishes and ring dishes. The fertilization method adopted is to directly add the processed sperm of a certain concentration into the well dish containing the eggs. Since all sperm can directly contact the egg, the viability, poor quality, and even the odds of abnormal sperm fertilizing the egg are greatly increased, which is not conducive to the formation of high-quality embryos and affects the clinical pregnancy rate. Contents of the invention [0003] In order to overcome the above disadvantages, the purpose of the present invention is to provide a fertilization culture dish, by improving the structure of traditional four-hole dish and ring dish used for fertilizat...
