由于微电子技术(ME)飞跃发展,临床检验许多专业都应用自动生化分析仪,推动了临床检验技术的进步。本文着重介绍引进血小板自动计数仪的应用情况及其存在的问题,供国内生产厂家及使用者参考。一、血小板计数仪原理血小板自动分析仪的计数原理与血细胞的自动计数原理基本相同,多是用电阻法。血小板悬浮于电解液(生理盐水)中,小孔管内外各装有一个电极,小孔管内的叫内电极,小孔管外的 Due to the rapid development of Microelectronics (ME), many professional clinical tests have applied automatic biochemical analyzers to promote the progress of clinical laboratory tests. This article focuses on the introduction of the application of automatic platelet count instrument and its existing problems for domestic manufacturers and users reference. First, the principle of platelet counting Platelet analyzer automatic counting principle and the principle of automatic counting of blood cells is basically the same, mostly by resistance method. Platelets suspended in the electrolyte (saline), each hole inside and outside the tube equipped with an electrode, the small hole called the inner electrode, outside the orifice tube
