The present disclosure discloses a magnetic bead removal method, device, and storage medium, including: placing a liquid bag with a curved flow channel on a magnetic platform, wherein a plane where the curved flow channel is located is above the magnetic platform and parallel to the magnetic platform; controlling a first flow control assembly to communicate the liquid bag with a sample container, thereby inputting a liquid containing immunomagnetic cells and non-magnetic immune cells into the curved flow channel from the sample container; performing a flattening operation on the liquid bag to increase a contact surface between a bottom surface of the curved flow channel and the magnetic platform, thereby adsorbing the immunomagnetic cells in the curved flow channel onto the contact surface through the magnetic platform; and performing a collection operation to collect the non-magnetic immune cells in the curved flow channel into a collection container.

Devices for monitoring cancerous cells in blood of a patient that are preloaded with a marker and a magnetic agent and removing them are provided. The device comprises a tray onto which blood withdrawn from the patient flows before returned to the patient; a magnet placed at a distance from the tray so that the blood on the tray is within a magnetic field of the magnet and the cancerous cells that are preloaded with the magnetic agent are forced to move from the blood on the tray towards the magnet. A detector configured to detect the marker in the cancerous cells in the blood on the tray is provided as well and a filter that is placed between the tray and the magnet so as to capture the cancerous cells that are forced to move towards the magnet and remove them from the blood of the patient.
