[0021] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-5 An exosome culture device includes a culture chamber 1, a partition plate 2 fixedly installed inside the culture chamber 1, a sealing cover 3 fixedly installed on the top of the culture chamber 1, a sample outlet hole 4 opened on the partition plate 2, a support platform 5 rotatably installed inside the culture chamber 1, a plurality of support columns 6 slidably installed on the top of the support platform 5, and a culture dish 7 is placed on the top of the plurality of support columns 6. The outer wall of the support column 6 is in contact with the inner wall of the sample outlet hole 4. During the process of cell culture to produce exosomes, when it is necessary to observe the culture dish 7 and perform other operations, the support platform 5 is rotated to rotate the selected culture dish 7 to be directly below the sample outlet hole 4. Then, the support column 6 is slid up so that the culture dish 7 extends out of the sample outlet hole 4 and the outer wall of the support column 6 is in contact with the inner wall of the sample outlet hole 4. At this time, the sealing cover 3 is opened. At this time, the culture chamber 1 is still isolated from the outside world, and the external environment will not affect the environment inside the culture chamber 1.

[0023] As a preferred embodiment, a motor 8 is fixedly installed at the bottom of the culture chamber 1, and a gear 9 is fixedly installed through the bottom of the culture chamber 1 at the output end of the motor 8. A gear ring 10 is fixedly installed at the bottom of the support platform 5, and the gear ring 10 meshes with the gear 9. Both the gear 9 and the gear ring 10 are rotatably installed at the bottom of the culture chamber 1. The motor 8 drives the gear 9 to rotate, thereby causing the gear ring 10 to rotate and thus driving the support platform 5 to rotate.

[0024] As a preferred embodiment, a slider 11 is fixedly installed on the bottom side wall of the support column 6. The slider 11 passes through the inner wall of the support platform 5 and slides with the support platform 5. A cylinder 12 is fixedly installed at the bottom of the culture chamber 1. An adapter block 13 is fixedly installed through the bottom of the culture chamber 1. The slider 11 and the adapter block 13 are engaged. The cylinder 12 and the adapter block 13 will engage with the slider 11 on the support column 6 which is rotated to the position directly below the sample outlet 4. Then, the output end of the cylinder 12 drives the adapter block 13 and the slider 11 to rise, thereby driving the support column 6 to rise.

[0025] As a preferred technical solution in this embodiment, a rubber ring 14 is fixedly installed on the top of the inner wall of the sample outlet 4, and an expansion port 15 is opened at the bottom of the sample outlet 4; the rubber ring 14 makes it fit more tightly with the inner wall of the support column 6, increasing the sealing performance, and the expansion port 15 facilitates the smooth entry of the support column 6 into the sample outlet 4.

[0026] As a preferred technical solution in this embodiment, a filling block 16 is fixedly installed at the bottom of the sealing cover 3. The filling block 16 is in contact with the top of the culture chamber 1 and the partition plate 2. When the culture chamber 1 is closed, the filling block 16 squeezes out all the external air at the top of the partition plate 2, preventing external air from remaining between the partition plate 2 and the sealing cover 3 and entering the interior of the culture chamber 1.

[0027] As a preferred technical solution in this embodiment, a plurality of damping rods 17 are fixedly installed on the support platform 5, and the plurality of damping rods 17 are respectively slidably engaged with the plurality of support columns 6; the stability of the support columns 6 during lifting and sliding is further increased by the slidable engagement between the damping rods 17 and the support columns 6.

[0028] As a preferred technical solution in this embodiment, an observation window 18 is rotatably installed on the top outer wall of the culture chamber 1; the inside of the culture chamber 1 can be simply observed through the observation window 18. When placing the culture dish 7 for the first time, the observation window 18 can be opened to quickly place the culture dish 7 into the culture chamber 1.

[0029] As a preferred technical solution in this embodiment, a support frame 19 is fixedly installed at the bottom of the culture chamber 1; the support frame 19 supports the entire culture chamber 1.

[0030] Overall work process:

[0031] When using this device to culture cells to obtain exosomes, first open the observation window 18, place the culture dishes 7 in batches on the top of the support column 6, then close the observation window 18 to continue cell culture. During the culture process, if it is necessary to remove the culture dish 7 for operation, rotate the culture dish 7 to be operated to the bottom of the sampling well. The rotation process is controlled by the motor 8. When the support column 6 corresponding to the culture dish 7 rotates to the bottom of the sampling well, the slider 11 on the support column 6 engages with the adapter block 13. The cylinder 12 drives the slider 11 and the adapter block 13 to rise, causing the support column 6 to rise. The support column 6 is tightly attached to the inner wall of the sampling well 4, so that the inside of the culture chamber 1 remains a sealed environment, preventing external air from entering the device.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
