Stem cell amplification device

Abstract

The invention relates to the technical field of stem cell amplification, in particular to a stem cell amplification device. The device comprises a workbench, a separation device, an extraction box, atransfer device, a culture dish and a culture solution spraying device. The workbench is arranged on a horizontal plane, the separation device is arranged on the workbench, the extraction box is arranged on the surface of the workbench and located beside the separation device, the transfer device is arranged on the workbench and located on the opposite side of the extraction box, and the culture dish is arranged on the workbench and located beside the transfer device. The culture solution spraying device is arranged on the workbench, and the spraying end of the culture solution spraying deviceextends into the culture dish. The separation device separates stem cells in blood, the extraction box extracts the stem cells, and the transfer device transfers the extracted stem cells into the culture dish. The culture solution spraying device sprays a culture solution on the surfaces of the stem cells uniformly, so that stem cell amplification is facilitated.

Description

technical field [0001] The invention relates to the technical field of stem cell expansion, in particular to a stem cell expansion device. Background technique [0002] For example, the patent with the publication number CN109290114A relates to a new type of wheel electroplating and spraying equipment for a stem cell expansion device; , rubber pad, compression spring, top column, liquid injection mechanism, push rod, push plate, liquid outlet tank, sealing column, return spring and connecting plate. The beneficial effects of the utility model are: the bottom of the bottle body of the utility model is slidingly connected with a push mechanism, and when the nutrient solution is injected into the bottle body, the base is pressed to realize the contraction of the compression spring, and the top column moves toward the bottle cap direction, and then The push rod moves the push plate to the side wall of the sealing plate, thereby realizing the contraction of the return spring, th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a stem cell expansion device to solve the problem that in the prior art, during large-scale culture, the cells need to be replaced every two days, and the cells need to be passaged in about four days. These daily maintenance operations need to consume a lot of The time and labor costs are high, and during the long-term culture process, it is necessary to repeatedly open the culture bottle for liquid replacement and passage operations, which greatly increases the risk of contamination.
