The present invention relates to a medical syringe, and more particularly, to a syringe for medical use, which is capable of separating blood by attaching it to a centrifuge without having to take blood from a human body and transfer it to a separate container, The present invention relates to a medical syringe kit capable of centrifugal separation and extracting a specific component from a blood sample, which can collect blood from a human body by pulling a separate syringe for taking a specific component from the separated blood into a gasket. For this purpose, a medical syringe kit capable of centrifugal separation and specific component extraction according to an embodiment of the present invention includes a first body in which blood is contained, a second body provided at one end of the first body, And a first gasket slidably moved along the longitudinal direction of the first body in the first body to generate a vacuum in a space in which blood is collected to collect blood from the human body, A second syringe for slidingly operating the first gasket while being attached to and detached from the first gasket and for extracting a specific component separated by centrifuging the blood contained in the first syringe； A cap for sealing the blood contained in the body so as not to be contaminated； a second syringe having a size smaller than that of the second syringe and being attached to and detached from the first fastening portion of the first syringe, A third syringe which is capable of extracting only a small amount of a specific component according to an amount of a specific component to be extracted after centrifugal separation, and a second syringe which is detachably attached to a first fastening part of the first syringe, And a joint for selectively connecting as needed.본 고안은 의료용 주사기에 관한 것으로, 보다 상세하게는 인체로부터 혈액을 채취한 후 별도의 용기에 옮길 필요 없이 바로 원심분리기에 장착하여 혈액을 분리할 수 있게 됨과 아울러 혈액을 채취하는 주사기에 별도의 플런저를 구비하지 않고 분리된 혈액에서 특정 성분을 채취하는 별도의 주사기를 가스킷에 끼워서 당겨줌에 따라 인체로부터 혈액
