Then, the control row key 101 is operated to control the control row key 101 to work with the electric push rod 202, so that the electric push rod 202 drives the tube rack 203 and the dropper 204 downward. The stem cells are collected and extracted by moving the dropper 204 to the place to be collected in the test tube. Then, the air bag at one end of the dropper 204 is manually pressed to collect and extract the stem cells. After the extraction is completed, the servo motor 301 can be controlled by the control key 101 to control the dropper 204 to move to the top of the culture box 205. Then, the air bag at one end of the dropper 204 is manually pressed to drop the stem cells into the culture box 205. This makes it easier for the collection and extraction device to place the extracted stem cells, thereby improving the convenience of placing the stem cells in the collection and extraction device and finally completing the use of the collection and extraction device.
