Description

Technical Field

[0001] The utility model relates to the technical field of cell screening, in particular to a cell screening device for stem cells. Background Art

[0002] By observing the cell preparation of various tissues of the human body, we can know whether the human body has lesions. The cell preparation process is as follows: first, the sample is collected, and then the sample is centrifuged for a specific time and number of times using a centrifuge, and the supernatant containing mucus, red blood cell fragments and other necrotic cell components is discarded, and then the cell adhesion packaging fluid is added, and finally a thin layer of cell smear with a single layer of cell distribution is made, and then artificial staining is performed. However, it is generally necessary to manually centrifuge the cells and discard the supernatant containing mucus, red blood cell fragments and other necrotic cell components. These preliminary treatments are often performed manually, and human error can easily cause the loss of diagnostic cells. In addition, the operator directly contacts the specimen, and the safety protection is poor;

[0003] After searching, the applicant found that a Chinese patent disclosed "a cell screening device for stem cells", and its publication (announcement) number is "CN106289908A".

However, it is inconvenient to disinfect after separation. Therefore, we propose a cell screening device for stem cells. Utility Model Content
