    • A method and apparatus are disclosed for measuring the aggregation of blood platelets or the coagulation of blood, the apparatus including a capillary tube for drawing blood, a piston in communication with the capillary tube and connected to a motor means for linear displacement thereof, a pressure sensor in the space located between the drawn blood and piston, and a computing means or microprocessing means for comparing the sensed pressure from the pressure sensor with a predetermined value, and providing a measured regulating output to the motor means. The method for measuring the aggregation of blood platelets and coagulation of blood includes the steps of drawing blood into the capillary tube of the moveable piston until the desired pressure is achieved within the capillary tube, and allowing the computing means to then maintain by adjustment of the piston position the pressure within the capillary tube. The computing means is able to determine the amount of blood flowing into the capillary tube during constant pressure regulation, and hence the amount of aggregate of blood platelets and blood coagulation due to a known relationship relating movement of the piston to blood drawn into the cylinder.
    • 公开了一种用于测量血小板聚集或血液凝固的方法和装置,该装置包括用于抽血的毛细管,与毛细管连通的活塞,并连接到用于其线性位移的马达装置,压力 传感器,其位于抽取的血液和活塞之间的空间中,以及计算装置或微处理装置,用于将来自压力传感器的感测压力与预定值进行比较,并向马达装置提供测量的调节输出。 用于测量血小板聚集和血液凝固的方法包括以下步骤:将血液吸入可移动活塞的毛细管中,直到毛细管内达到所需的压力,然后允许计算装置通过调节 活塞定位毛细管内的压力。 计算装置能够确定在恒定压力调节期间流入毛细管的血液量,并因此确定由于已知关系使血小板凝集的聚集体和血液凝固的量,使活塞与吸入气缸的血液相关。
