血沉能说明血浆蛋白的比例,可作为医师的一种诊断手段。但在一般情况下,要在取血后二小时才可得到血沉率,使得病员要等待一段较长的时间。现时研究出一种血沉率的快速自动测定法并制造了一台实验样机,能在几分钟内当病人还在场时就出报告。血清和红血球之间边界层的读数通过光电学方法求出。以一发脉动绿光的光电二极管照过含有血标本的吸移管,经光学放大后在光接收器上形成摹拟图象。在光电学上,可将在血清和血浆之间或多
ESR can explain the proportion of plasma proteins can be used as a diagnostic tool for physicians. However, under normal circumstances, the blood sedimentation rate should be obtained two hours after the blood is drawn, so that the patient should wait for a longer period of time. A quick automated assay of erythrocyte sedimentation rate has been developed and an experimental prototype has been developed that reports when the patient is still present within minutes. The boundary layer readings between serum and erythrocytes were found by the method of optoelectronics. A pulsating green photodiode shines through the pipette containing the blood sample and is optically amplified to form a simulated image on the photoreceiver. Optoelectrically, there can be between serum and plasma or more
