Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Unless otherwise indicated, the technical means used in the examples are conventional means well known to those skilled in the art.

Referring to fig. 1-4, the utility model discloses a 3D cell culture dish, including culture dish 2 that has ware lid 1 and the base plate 3 that is used for placing a plurality of culture dish 2, be provided with fixed bolster 4 in the culture dish 2, the top edge of fixed bolster 4 is provided with the crotch 5 that the several caught on culture dish 2 edge and outside the bend of culture dish 2, the symmetry is provided with two arcs on the 2 inner walls of culture dish, be provided with the arch with arc groove looks adaptation on the lateral wall of fixed bolster 4, the arc setting leans on the position at culture dish 2 middle parts, avoids the culture medium to arrange in the arc. It should be understood that: a plurality of arc-shaped grooves are sequentially arranged on each row of arc-shaped grooves from top to bottom at equal intervals, and the arc-shaped grooves on each row are symmetrical. When the bottom of the fixed support 4 is contacted with the bottom of the culture dish 2, namely, the fixed support 4 is completely arranged at the bottom of the culture dish 2; the bulges are arranged in the arc-shaped grooves close to the bottom of the culture dish 2, namely, only two bulges are arranged on the outer side wall of the fixed support 4 and are symmetrically arranged. The bulge is made of plastic, the diameter of the bulge is smaller than that of the arc-shaped groove, and when the fixing support 4 is lifted upwards, the bulge can be moved out of the arc-shaped groove and enters the next arc-shaped groove. Moreover, a certain gap is formed between the outer side wall of the fixing bracket 4 and the inner wall of the culture dish 2, so that the fixing bracket 4 can move up and down conveniently.

Referring to fig. 5-6, when only one groove 6 for placing the culture dish 2 is formed in the substrate 3, a plurality of supporting bases 7 extending toward the center of the groove 6 are transversely formed on the surface of the substrate 3, and the end surfaces of the supporting bases 7 are arc-shaped and attached to the outer wall of the culture dish 2. The bottom of recess 6 transversely is provided with backup pad 8, and is fixed through telescopic link 9 between backup pad 8 and the recess 6. It should be understood that: the telescopic link 9 can set up a plurality ofly, and the setting of backup pad 8 and telescopic link 9 is convenient for adjust the height of culture dish 2 in recess 6 to the height of adjustment fixed bolster 4 in culture dish 2, thereby the cell culture of adaptation different grade type.

Further, in order to adjust the height of the fixing bracket 4 in the culture dish 2 during the process of culturing the cells, fixing columns 10 are fixed at the bottom of the culture dish 2 and are arranged to intersect with each other, the two fixing columns 10 have a certain angle and are arranged according to actual conditions, and in order to avoid the fixing columns 10 from shaking on the support plate 8, the fixing columns 10 are arranged to be rectangular, the length of the fixing columns is greater than half of the diameter of the culture dish 2, and therefore the stability of the culture dish 2 is improved. Fixing grooves 11 are formed in two ends of each fixing column 10 along the length direction of the fixing column, and the sum of the lengths of the two fixing grooves 11 is smaller than that of the fixing column 10. Two fixing grooves 11 of one fixing column 10 are internally provided with a Z-shaped pressing rod 12, the other end of the pressing rod 12 extends out of the groove 6, and the length of a cross rod below the pressing rod 12 is larger than that of a cross rod above the pressing rod; when the culture dish 2 is placed on the support plate 8, the bottom surface of the hook 5 is just abutted against the table surface of the support table 7. It should be understood that: the height of the bottom edge of the dish cover 1 is lower than the length of the hook 5 on the outer wall of the culture dish 2, namely the hook 5 extends out of the dish cover 1, so that the height of the fixed support 4 in the culture dish 2 is adjusted without moving the dish cover 1. The pressing rod 12 penetrates out of the space between the two adjacent supporting platforms 7, and the cross rod above the pressing rod 12 is far away from the plate surface of the substrate 3. Moreover, when the projection is positioned in the arc-shaped groove close to the opening of the culture dish 2, the cross rod above the pressure rod 12 is just arranged on the plate surface of the base plate 3.

Further, in order to avoid the dish lid 1 to move on the culture dish 2 or drop because of the touching, be provided with breach 13 at the interior top surface of dish lid 1, make the crotch 5 that is located on 2 top edges of culture dish just arrange in breach 13, and culture dish 2 is except contacting with top surface and the interior top surface contact of dish lid 1 with crotch 5 except, thereby place dish lid 1 stably on culture dish 2, even adjust the height of fixed bolster 4, dish lid 1 also can be stabilized on crotch 5 of card on fixed bolster 4.

Referring to FIG. 7, a plurality of grooves 6 for holding culture dishes 2 are formed on a substrate 3, so that cells of different types or the same type can be cultured simultaneously in a large scale.

When using the utility model discloses the time, adjust the bottom of culture dish 2 with fixed bolster 4 in advance, put culture medium and cell lid good dish lid 1. Then, a zigzag pressing rod 12 is inserted into two fixing grooves 11 of one of the fixing posts 10, or a pressing rod 12 is inserted into each fixing groove 11, and the arrangement is performed according to actual conditions. Then, the press lever 12 is lifted to move the culture dish 2 into the groove 6 on the substrate 3, and the culture dish 2 is placed in the support plate 8, and at this time, the bottom surface of the hook 5 located outside the culture dish 2 is placed on the outside of the support table 7, thereby performing 3D culture of the cells.

If at the in-process of carrying out the cultivation to the cell, need adjust the height of fixed bolster 4, only need push down depression bar 12, telescopic link 9 is compressed, backup pad 8 moves down, depression bar 12 takes culture dish 2 downstream, because the crotch 5 of fixed bolster 4 offsets with a supporting bench 7, therefore, only culture dish 2 downstream, the arch moves towards the arc wall of 2 openings parts of culture dish gradually, adjust suitable position until fixed bolster 4, simultaneously, the arc wall is arranged in to the arch, thereby fix fixed bolster 4 in culture dish 2, until accomplishing the cultivation of cell.
