实用型电子扫描全自动血型鉴定仪的研制

目的:研制一种适合二级或二级以上的医院及献血中心、血站等单位且能方便、快速、准确的判断血型的实用型全自动血型鉴定仪.方法:主要采用电子扫描(SCA)放大图像比对系统的技术,将所需试剂和标本放到指定位置,用特制凹型平底三孔玻片自动推至于载体板上,微量样品经稀释可通过振荡1 min准确与试剂发生反应,并观察其是否产生凝集现象;通过扫描系统检测,经过软件处理自动得到结果.结果:研制实用型全自动血型鉴定仪能快速、准确地鉴定血型,可达到120份/h左右,自动判断错误报警、提示错误操作.结论:研制的实用型全自动血型鉴定仪操作简便,设计合理,且快捷灵活,适应性强.

Development of a new practical SCA automatic blood type identification instrument

Objective： To develop a new practical automatic blood type identification instrument suitable for use in such institutions as grade-Ⅱ hospitals, blood centers or blood stations. Methods： The electronic scanning（SCA）magnification image comparison technology was used. The reagent and specimen were put into the specified location, with a special concave bottom hole slide automatically pushed as far as the carrier sheet. Trace sample was diluted by oscillating one minute. Then the results were obtained by software. Results： The practical development of full automatic blood type identification instrument for rapid and accurate identification of blood group has been finished. It could identify samples at a speed of 120 / h. Meanwhile, the system could automatically inform the mistaken alarms and manipulation. Conclusion： The system developed by us is simple to use, reasonable in design. Furthermore, it is flexible and fast and has strong adaptability.
