Detailed ways

The principles and features of the present invention are described in the following with reference to the accompanying drawings, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

Please refer to FIG. 1 and FIG. 2 simultaneously, which is a petri dish for observing and cultivating an embryo according to the present invention, which comprises a dish slot 1, a plurality of washing chambers 2 disposed in the dish slot 1 and a plurality of specimen placing chambers 3 The information marking unit 4 is provided on the dish 1.

The dish 1 includes a first plate body 11, a second plate body 12 extending downward from a central portion of the first plate body 11, and a third plate body 13 extending upward from a central portion of the first plate body 11. The second plate body 12 and the third plate body 13 are integrally formed with the first plate body 11. The dish 1 forms a recess 14 downwardly from its top.

The first plate body 11 is a circular flat plate having an anti-slip pattern 111 at its edge to prevent slipping when taken.

Referring to FIG. 3 , the outer surface of the second plate body 12 is provided with a first positioning structure 121 , and the bottom surface of the second plate body 12 is provided with a second positioning structure 122 . Specifically, the first positioning structure 121 is a positioning post and has a trapezoidal or wedge-shaped cross section; the second positioning structure 122 is a positioning groove and has a trapezoidal or wedge-shaped cross section. The first positioning structure 121 and the second positioning structure 122 can ensure the fixed direction and position of the entire culture dish, and achieve precise positioning.

The third plate body 13 has a D shape.

The groove 14 extends from the third plate body 13 to the second plate body 12 and is spaced apart from the bottom surface of the second plate body 12.

The plurality of lavatory 2 and the plurality of specimen placing chambers 3 are both disposed in the recess 14 of the dish 1 and at the bottom of the recess 14, and the height of the lavatory 2 and the specimen placing chamber 3 is lower than the depth of the recess 14. .

The lavatory 2 has a cylindrical shape for cleaning microorganisms.

Referring to Figure 4, the specimen placement chamber 3 is used to place microorganisms. The bottom of the specimen placing chamber 3 has a concave guiding groove at the center, and the concave guiding groove has a two-stage taper, so that microorganisms can be gradually guided to the center bottom position of the specimen placing chamber 3, and the specimen is prevented from shaking.

In the present embodiment, the lavatory 2 has three and is arranged in a row; the specimen placement chamber 3 has sixteen, and two rows are arranged, eight in each row, and the surrounding is provided with an identifiable number identification.
