在体实时血液粘度的测量研究

传统的血液粘度测定方法均采用离体测量方式、存在着测量时间长,测量过程中干扰困素多,测量后的血样被破坏等缺点,因此在测量速度、精度及重复性方面均不令人满意。为此我们提出了一种快速实时测量新鲜血液粘度的新方法,即利用特制针头作为测量毛细管,在采血过程中实现血液粘度的测量。这种新方法具有用血量少、测量快速,重复性好的优点,具有很重要的临床应用价值。

Study of an In-vivo and Real-time Method to Measure Blood Viscosity

The traditional methods to measure blood viscosity are out line. They have the disadvantages of long measurement time, many disturbance factors during measurement, the damage to blood sample, and etc. So rapidity, accuracy and repeatability are not satisfactory. A new method to measure blood viscosity is proposed in this paper, which uses needle instead of capillary and can measure blood viscosity during collecting blood. Owing to the advantages of small amount of blood sample, rapidity and repeatability, the new method is of value for clincal application.
