Multipurpose culture vessel for assisting reproduction test

Abstract

The invention discloses a multipurpose petri dish for an assisted reproduction test; it comprises a petri dish and a dish cover, the petri dish includes a dish body, an egg placing cup, a plurality of sperm placing cups and a plurality of sperm channels; a columnar holder is arranged in the middle of the dish body The egg placing cup is fixed on the column-shaped support table; a plurality of sperm placing cups are arranged in the main body of the dish surrounding the egg placing cup, and the height of the mouth of the multiple sperm placing cups is slightly lower than the height of the bottom of the egg placing cup. The outer walls of a plurality of sperm placement cups are respectively provided with sperm lead-out ports near the mouth of the cup, and the outer walls of a plurality of egg placement cups are respectively opened with sperm lead-out ports near the bottom of the cup; between the sperm introduction port. Beneficial effect: the multiple sperm channels are all inclined, which can better reflect the survival of the fittest in sperm swimming, so that only the sperm with the best activity can swim to the egg placing cup through the sperm channel and combine with high-quality eggs. Strong practicability and good use effect.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multipurpose petri dish for assisted reproduction experiments. Background technique [0002] A petri dish, as the name suggests, is a laboratory vessel used for microorganism or cell culture. A traditional petri dish consists of a disc-shaped main body and a cover, which are generally made of plastic or glass. Plastic is suitable for laboratory inoculation, streaking and isolation of bacteria, and can also be used for cultivation of plant materials. Glass can be used for plant material, microbial culture and animal cell adherent culture. [0003] And for the traditional in vitro fertilization culture dish, it generally is to directly arrange the sperm placement cavity and the egg placement cavity in the corresponding culture dish, and connect a sperm guide channel horizontally in the middle part of the outer wall between them, so that the activity is good. The sperm...

[0003] And for the traditional in vitro fertilization culture dish, it generally is to directly arrange the sperm placement cavity and the egg placement cavity in the corresponding culture dish, and connect a sperm guide channel horizontally in the middle part of the outer wall between them, so that the activity is good. The sperm can run to the egg placement cavity through the corresponding sperm guide channel and combine with the egg placed in it, so as to achieve the purpose of egg fertilization in vitro. Although this method is widely used, it still has certain defects and deficiencies.

[0004] Specifically, on the one hand, the sperm with good motility could not find the sperm-guiding channel, lost their way and remained in the corresponding sperm placement cavity, while the sperm with poor motility might run to the egg placement cavity through the corresponding sperm-guiding channel The combination with the eggs placed in it makes it impossible to efficiently ensure the combination of excellent sperm and eggs, which will affect the quality of t
