Enhanced yield collection systems and methods for obtaining concentrated platelets from platelet-rich plasma

摘要

A separation zone for separating platelets from a platelet- rich suspension establishes a relationship between its radial thickness (h) and axial height (Z) that, taking into account the given angular velocity of rotation and the given kinematic viscosity of the platelet- rich suspension introduced through the inlet, represents a () value that is less than 700,PPwhere ##EQU1## where: is the angular velocity (in rad/sec);PPh is the radial depth (or thickness) of the chamber (in cm);PP is the kinematic viscosity of the fluid being separated (in cm.sup.2 /sec); andPPZ is the axial height of the chamber (in cm).
