Method and apparatus for separating fluid components

The device for separating the fixed members of physiological liquid (12, 13 and 14) and floater unit, comprising a capable of the relative motion two parts (120 and 122). When the two parts of the two separation degree when the largest, wherein two parts with angle between them a predetermined volume, and a part (122) can the extrusion hole comprises to one part (120) of the two parts (120 and 122) between the liquid. The two parts of a is made of them located on the position density material in the liquid wants is made, is made of the member and easy to gain and pushing.
