The present invention provides an embryo culture dish, which comprises a plurality of culture chambers disposed on the bottom surface thereof, and can culture embryos in different areas at the same time.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

the utility model provides an embryo culture dish, includes the culture dish body, is provided with the culture tank that the multiunit is the extension of arc form on the bottom surface in the culture dish body, and the bottom surface is provided with the culture room of cultivateing embryo usefulness in the culture tank.

As an option, the number of the culture tanks is more than 2 groups, and the culture tanks are concentrically arranged on the inner bottom surface of the culture dish body. Preferably, a plurality of culture chambers are uniformly distributed in each group of culture tanks.

As an option, the culture trough extends in a circular shape on the inner bottom surface of the culture dish body, and the cross section of the inner bottom surface is in an arc shape. Thus, the flowing and cleaning of nutrient solution and the like are facilitated.

As an option, the depth of the inner bottom surface of the culture tank becomes gradually deeper as it approaches the culture chamber. Therefore, the embryo and the culture solution are favorably gathered at the position of the culture chamber, the placement is convenient, and the embryo can be prevented from being separated from the culture chamber and mixed with the embryos in other culture chambers due to the reasons of movement and the like.

As an option, the culture chamber is a spherical or ellipsoidal recess. Therefore, the nutrient solution and the like can flow and be cleaned conveniently, and the embryo can be better developed by matching the spherical structure of the embryo.

As an option, the number of culture tanks is 2 groups, the depth of the inner bottom surface of the culture tanks of 2 groups is 2mm, and the width of one group of culture tanks is 1mm, and the width of the other group of culture tanks is 2 mm.

Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:

the embryo culture dish of the utility model is provided with a plurality of groups of culture tanks on the inner bottom surface and culture chambers in the culture tanks, thereby forming subareas and culturing embryos at fixed points; moreover, the arc-shaped culture tank simulates the human oviduct reproductive system, so that the embryo can be better developed.

Detailed Description

Example 1

Referring to fig. 1-2, the embryo culture dish of the present embodiment includes a culture dish body 1, a plurality of sets of culture tanks (2, 21) extending in an arc shape are disposed on the inner bottom surface of the culture dish body 1, and culture chambers (3, 31) for culturing embryos are disposed on the inner bottom surface of the culture tanks.

The inner bottom surface of the culture dish is provided with a plurality of groups of culture tanks and a culture chamber, so that a subarea is formed and embryos can be cultured at fixed points; moreover, the arc-shaped culture tank simulates the human oviduct reproductive system, so that the embryo can be better developed.

The number of culture tanks is 1 or more than 2, taking two

culture tanks

2 and 21 as an example, the two culture tanks extend on the inner bottom surface of the culture dish body in a circular shape and are positioned at concentric circles, the radiuses of the middle parts of the culture tanks are r1 and r2 respectively, the depth of the culture tanks is c, the width of one culture tank is a, and the width of the other culture tank is b.

A plurality of culture chambers, specifically 1 or more, in this embodiment 2 culture chambers (culture chamber 3 or culture chamber 31), are uniformly distributed in each group of culture tank.

Specific dimensional parameters are exemplified below.

The number of culture tanks is 2 groups, the depth c of the inner bottom surface of the culture tanks of 2 groups is 2mm, and the width a of one group of culture tanks 2 is 1mm, and the width b of the other group of culture tanks 21 is 2 mm.

In one embodiment, the cross section of the bottom surface of the culture tank is preferably circular arc-shaped to facilitate the flow and cleaning of nutrient solution.

In one embodiment, the culture chamber is preferably a spherical or ellipsoid shaped recess for cleaning and matching the spherical shape of the embryo to allow better development and growth.

Example 2

The difference between this example 2 and example 1 is the number distribution of the culture chambers, specifically:

referring to FIG. 3, 4 culture chambers are uniformly distributed in each of the

culture tanks

2 and 21.

Example 3

The difference between this example 3 and example 1 is the culture chamber data distribution, specifically:

referring to fig. 4, 3 culture chambers 3 are uniformly distributed in the culture tank 2; the culture tank 21 is uniformly distributed with 6 culture chambers 31.

Example 4

The difference between this example 4 and example 1 lies in the bottom structure of the culture tank, specifically:

referring to FIG. 5, the depth of the inner bottom surface of the culture tank (2, 21) becomes gradually deeper as it approaches the culture chamber. The bottom surface of the culture tank is in a wave-shaped peak valley structure, an inclined plane or an arc inclined plane is gradually changed, the culture chamber is arranged to be a low point, the culture chamber gradually becomes high towards two sides, and a peak point exists between the culture chambers.

Therefore, the embryo and the culture solution are favorably gathered at the position of the culture chamber, the placement is convenient, and the embryo can be prevented from being separated from the culture chamber and mixed with the embryos in other culture chambers due to the reasons of movement and the like.

Example 5

The difference between this example 5 and example 4 is the shape of the culture tank, specifically:

referring to fig. 6, the culture tanks (2, 21) are extended in an arc structure and are positioned on a concentric track, the middle parts of the culture tanks are provided with culture chambers (3, 31), and the positions of the culture chambers are gradually higher towards the two sides of the culture chambers from low points to high points until the culture chambers extend to the inner bottom surface of the culture dish body.

It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like, when referring to the orientation or positional relationship shown in the drawings, are only used for convenience of description and simplicity of description, and do not indicate or imply that the referred device or element must have a particular orientation, be constructed in a particular orientation, and be operated.

The above description is intended to illustrate and describe the preferred embodiments of the invention, but not to limit the scope of the invention, and all equivalent changes and modifications made in accordance with the teachings of the present invention are intended to be covered by the present invention.
