A new capillary system was developed, incorporating infrared sensors, which allowed the determination of whole blood viscosity over a wide range of shear stresses. Flow conditions were defined by the geometry of the capillary and the sample pressure head. Whole blood was considered to be a power law fluid and a modified Mooney's formula was used for the calculation of the related invariants. The new viscometer proved to be very simple in use, requiring one run, had a short measuring time and utilised a small test sample volume. However it can be used for whole blood viscosity measurements only at medium and high shear stresses.
开发了一种新的毛细管系统，该系统集成了红外传感器，可在很宽的剪切应力范围内测定全血粘度。流动条件由毛细管的几何形状和样品压头确定。全血被视为幂律流体，并使用修正的穆尼公式计算相关不变量。这种新型粘度计使用起来非常简单，只需一次测量，测量时间短，且所需的测试样品量小。然而，它只能用于中高剪切应力下的全血粘度测量。
