METHOD AND APPARATUS FOR SEPARATING FLUID COMPONENTS

摘要

A floating element for separating components (12, 13, 14) of a physiological fluid comprises two parts (120, 122) that are relatively movable. The two parts (120, 122) define a prescribed volume between them when at their maxim um separation, and one of the parts (122) may be moved toward the other (120) t o express the fluid contained in the volume between the parts (120, 122). The parts are made of materials having densities so that they assume a desired position in the fluid to allow selected components to be easily obtained and expressed.
