采血方法 正确采集血样本是获得准确、可靠实验结果的关键。在样本采集前,应根据实验要求,决定采血方法、所叙血量及适用抗凝剂。 （一）静脉采血法 1.概叙 静脉采血多用于体表的浅静脉,通常采用肘部静脉、手背静脉、内踝静脉或股静脉。小儿可采颈外静脉血液。根据采血量可选用不同型号注射器,配备相应的针头。某些特殊检查,为避免血小板激活,要使用塑料注射器和硅化处理后的试管或塑料试管。目前,已有商品化的真空采血系统的采血法。 2.操作方法 (1)准备试管：取合适数量和规格的试管备用。 （2）检查注射器：打开一次性注射器包装,左手持针头下座,右手持针筒,将针头和针筒紧密连接,并使针头斜面对准针筒刻度,抽拉针栓检查有无阻塞和漏气。最后排尽注射器中的空气，备用。 (3)选择静脉：患者取坐位,前臂水平伸直置于桌面枕垫上。暴露穿刺部位,选择容易固定、明显可见的肘部静脉。 （4）消毒：先用30g/L碘酊棉签自所选静 …

第一篇 临床检验基础 第一章 血液样本采集和血涂片制备 一.血液生理概要 （一）血液组成 血液由血细胞（红细胞、白细胞、血小板）和血浆组成。离体后的血液自然凝固,分离出来的淡黄色透明液体称为血清。血液加抗凝剂后分离出来的淡黄色液体称为血浆。血清与血浆差别是：血清缺少某些凝固因子,如凝血因子I（纤维蛋白原）、II（凝血酶原）、V、VIII等。 全血适用于临床血液学检查,如血细胞计数、分类和形态学检查等。血浆适用于血浆生理性和病理性化学成分的测定,特别是内分泌激素测定;血浆除钙离子外,含有其他全部凝血因子,也适用于血栓与止血的检查。血清适用于临床化学和临床免疫学检查。 （二）血液理化性质 1.血量 正常人血量约为（70±10）ml/kg体重,成人约4~5L,约占体重的6%~8%,其中血浆占55%,血细胞占45%。小儿血量与体重之比略高于成人,男性比女性血量稍多,但女性妊娠期间血量可增 …

Move static content to static Jekyll has a rule that any directory not starting with _ will be copied as-is to the _site output. Hugo keeps all static content under static. You should therefore move it all there. With Jekyll, something that looked like ▾ <root>/ ▾ images/ logo.png should become ▾ <root>/ ▾ static/ ▾ images/ logo.png Additionally, you’ll want any files that should …
