The present invention relates to a syringe for separating PRP blood component, more specifically to one end in the multi-stage unit a coupling pipe (11) is formed, the handle projecting on both sides to place a finger in the end portion 12 is formed in the cylinder 10 The cylinder is inserted into the cylinder to move in all directions and, in a longitudinal direction (10), once the rubber packing 21 is installed on the part around in a tight contact state at the inside of the cylinder 10, After the piston to provide a compressive force or a suction force while moving in direction 20 The coupling tube 11 is coupled detachably to the injection needle (30) In the syringe to the patient that are configured to ipchim, is formed by the combination of the cylinder tube end portion of the separated components of the blood (10) to facilitate 11-shaped cross-sectional area is gradually reduced to a point formed (13, 14) and that formed in the shape corresponding to the shape of the cylinder 10 to move to the rubber packing piston cylinder 10 and the airtight contact state of the piston 20, characterized in that on the configuration. In addition, PRP relates to a separation method using a syringe for separating blood components, and more particularly, formed in one end portion coupled tube (11) shaped to reduce the cross-sectional area toward the point formed by 13 and 14 of the cylinder 10 preparing a syringe (S100) Comprising sampling of blood by using the ready syringe (S200) Cellular components of the lower layer by centrifuging the blood, and blood, PRP component of the intermediate layer, separating the upper layer of the PPP component (S300) And the cellular components of the separated blood, PRP components, comprising separate storage containers to each other using PPP component (S400) And characterized in that it comprises a configuration on that. According to a syringe for blood component separation PRP proposed in the present invention, the PRP separated blood comp
