目的：分析影响全血采集时间的多种因素，应用于有针对性地减少无偿献血中的全血采集时间延长，以提高血液质量。方法以Compoguard Complete全自动采血混合仪为主体，利用其各种控制功能、数据处理能力和良好的通讯功能，以及与血站计算机管理系统的实时联网，统计分析一定时间段内所有全血的采集时间，进而分析多种因素对全血采集时间延长的影响。结果全血采集时间延长的比率为7.09%，采血时间延长组的平均采血时间延长260.03 s（P<0.05）；平均流速慢44.17 mL/min（P<0.05）；平均年龄分别小3.94岁（P<0.05）。对不同影响因素进行单因素分析发现，不同采血方式、采血量、性别、年龄段、采血环境、采血护士均有统计学差异（P<0.05）；对血液采集时间延长多因素Logistic回归分析发现，变量采血量、性别和年龄有统计学差异（P<0.05）。采血量为300 mL时相关系数为3.91(Exp(B)=49.92，95%CI=23.42~106.42，P=0.00)，采血量为400 mL时相关系数为1.96(Exp(B)=7.10，95%CI=4.60~10.96，P=0.00)；性别的相关系数是-0.52(Exp(B)=0.59，95%CI=0.49~0.72，P=0.00)；年龄的相关系数是0.04(Exp(B)=1.04，95%CI=1.03~1.05，P=0.00)，即采血量较多的年龄较大的女性容易产生血液采集时间延长。结论针对影响全血采集时间的因素，可以采取有针对性的预防措施，以有效地减少全血采集时间延长。

Objective To analyze the multiple factors affecting the whole blood-collecting time and to improve the blood quality by reducing the whole blood collecting time in gratuitous blood donation. Method We counted and analyzed all the whole blood-collecting time in a certain period of time and also analyzed the effect of multiple factors on prolongation of whole blood-collecting time by using a variety of control function, data processing capability and good communication of Compoguard Complete automatic blood-collecting mixer as well as real-time network access to computer management system of blood station. Results The ratio of prolonged whole blood-collecting time was 7.09%. In the group with prolonged blood-collecting time, the average time was 260.03 s (P<0.05) longer;average velocity was 44.17 mL/min (P<0.05) slower;mean age was 3.94 years (P<0.05) smaller. We found that there is statistical difference due to different blood-collecting method, amount of blood collected, gender, age, blood-collecting environment and nurses collecting the blood (P<0.05), Multivariate Logistic regression analysis showed that there were statistical difference in volume of blood collected, sex and age (P<0.05). The correlation coefficient were 3.91 (Exp (B)=49.92, 95%CI=23.42-106.42, P=0.00) and 1.96 (Exp (B)=7.10, 95%CI=4.60-10.96, P=0.00) when 300 mL and 400 mL blood were collected respectively;while the correlation coefficient for sex and age were-0.52 (Exp (B)=0.59, 95%CI=0.49-0.72, P=0.00) and 0.04 (Exp (B)=1.04, 95%CI=1.03-1.05, P=0.00) respectively, namely older women who collected more whole blood could bring about prolonged blood-collecting time. Conclusion Prolonged whole blood-collecting time could be effectively reduced by taking precautions targeting at factors affecting the blood-collecting time.
