The invention relates to a lymphocyte extraction device and an extraction method. The lymphocyte extraction device comprises an injector, a separating medium displacer and a filter device, wherein the injector consists of an outer tube body, a pull handle, a piston and a needle head; the connection section of the separating medium displacer is detachably connected with the outer tube body; the filter device comprises a connection tube, a liquid storage tube and a mixed cellulose filter membrane placed in the connection tube; a liquid inlet is formed in the bottom of the liquid storage tube and is connected with a liquid suction pipe, and a liquid outlet is formed in the side wall of the liquid storage tube and is connected with a liquid discharging pipe; check valves are arranged at the liquid inlet and the liquid outlet; and the upper end of the connection tube is detachably connected with the outer tube body. According to the extraction method implemented through the device, cells to be extracted can be always retained in the original container, and unnecessary cells and plasma can be easily and conveniently removed, so that time and labor for cell separation and extraction are greatly saved, the working efficiency is high, more cells with higher purity are extracted, and the possibility of pollution is lower.
