Blood component separation and storage device and method for preparing platelet-rich plasma

摘要

To provide a blood component separation / accommodation apparatus and a method for preparing platelet-rich plasma that can more easily and aseptically separate and accommodate platelet-rich plasma. A blood component separation / accommodation apparatus 1 comprising a blood storage unit 2, a component storage unit 3 that stores some components of blood, and a connecting tube 4 that connects the blood storage unit 2 and the component storage unit 3. The blood storage unit 2 derives some components of blood from the flexible cylindrical blood storage container 21, the blood introduction path 27 for introducing blood into the blood storage container 21, and the blood storage container 21. The component storage section 3 includes a component introduction path 37 through which a part of blood derived from the blood storage container 21 is introduced, and the component introduction path 37 to the inside of the component storage section 3. The present invention relates to a blood component separation / accommodation apparatus 1 having a metal needle 371 extending toward a space and capable of returning a part of blood stored in a component storage unit 3 toward a blood storage container 21.
