Title:
軟膜セパレータフロートシステムおよび方法
Document Type and Number:
Japanese Patent JP2013528785
Kind Code:
A
Abstract:
Tube and float systems for separation and axial expansion of the buffy coat are provided. Generally, the systems include a flexible sample tube and a rigid separator float having a specific gravity intermediate that of red blood cells and plasma. The sample tube has an elongated sidewall having a first cross-sectional inner diameter. The float has a main body portion and one or more support members protruding from the main body portion to engage and support the sidewall of the sample tube. During centrifugation, the centrifugal force enlarges the diameter of the tube to permit density-based axial movement of the float in the tube. After centrifugation is ended, the tube sidewall returns to its first diameter, thereby capturing the float and trapping the buffy coat constituents in an annular volume. Several different systems for capturing and retrieving the buffy coat constituents are described.
