    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for transporting fluids in channels and reducing contamination and/or dilution of a fluid being transported, in which the fluid is manipulated and dispensed with less contamination or dilution of the fluid. SOLUTION: The method includes: providing a working fluid to transport the desired fluid, such as a sample; providing a first segment of a first buffer fluid which is immiscible with the working fluid and the desired fluid; providing a first segment of the desired fluid; providing a second segment of a second buffer fluid which is immiscible with the working fluid and the desired fluid; providing the desired fluid to be transported and further manipulated; and transporting the desired fluid in the channel by applying a motive force to the working fluid which in turn exerts force against the desired fluid through the first and second buffer fluid. The method prevents the dilution of a sample in an apparatus such as a diagnostic analyzer or an apparatus for immunohematological testing of blood. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供一种用于在通道中输送流体并减少被输送的流体的污染和/或稀释的方法和装置,其中流体被操纵并且排出较少的流体的污染或稀释。 解决方案:该方法包括:提供工作流体以输送所需流体,例如样品; 提供与工作流体和所需流体不混溶的第一缓冲流体的第一段; 提供所需流体的第一段; 提供与工作流体和期望流体不混溶的第二缓冲流体的第二段; 提供要运输和进一步操纵的所需流体; 以及通过向所述工作流体施加动力来输送所述通道中的所需流体,所述工作流体又通过所述第一和第二缓冲流体对期望的流体施加力。 该方法防止样品在诸如诊断分析仪或血液免疫血液学检测装置之类的装置中稀释。 版权所有(C)2005,JPO&NCIPI
