AI Technical Summary
Technical Problem
[0004]此外临床生化检测中，装置往往仅仅设置有限的试剂一针和试剂二针，该两个针分别根据检测项目分别吸取不同的试剂一及试剂二，并将所吸取的试剂分别加入不同检测杯中，而不同试剂性质、成分、颜色等往往不同，而全自动生化检测装置运行速度较快，往往无法给予更多时间进行清洗，尤其高速全自动生化检测装置往往无法完全彻底执行试剂针内外清洗，现有的全自动生化检测装置尽管试剂针在每次吸取试剂前或后都要进行清洗，但难免残留之前接触的试剂，这些残留试剂与新吸取试剂的交叉将导致所用于检测的试剂不纯造成分配试剂的交叉污染，且每次对针清洗需要耗费较多的水
Benefits of technology
[0021]本发明设计的一种高速低交叉污染的全自动生化检测装置，采用同一个试剂臂所携带的一个试剂针一次吸取一份及以上试剂，随后一次分配至多个不同的检测杯，这样大大节省试剂针吸取及分配试剂所消耗时间，有效提高装置运行速度。
