Definitions
- the present invention relates to a container used in a centrifuge for separating components having different components or specific gravity by using centrifugal force.
- Blood a liquid tissue that flows through blood vessels, is roughly divided into blood cells and plasma.
- Blood cells are composed of red blood cells, white blood cells and platelets, and mainly water plasma contains blood coagulation factors and electrolytes essential for life support.
- the container when the collected blood is injected into the container, the container is placed in a centrifuge, rotated at a predetermined rotational speed, and then precipitated, and the components of the blood are separated by the specific gravity. That is, heavy blood cells are formed in layers at the bottom, light plasma is formed in layers at the top, and a buffy coat layer, which forms about 1% of blood, is formed between the blood cells and the plasma.
- PRP Platinum Rich Plasma
