一种血液分离预处理芯片及血液分离装置
摘要：
本实用新型提供一种血液分离预处理芯片及血液分离装置，包括沿血液流向依次排列的至少一个微柱阵列，每个所述微柱阵列的柱间距均不相同，所述至少一个微柱阵列的柱间距按照所述至少一个微柱阵列的排列顺序依次减小，所述至少一个微柱阵列至少包括红细胞截留微柱阵列；所述红细胞截留微柱阵列对所述血液中的红细胞进行截留，以过滤所述血液中的红细胞；血液从所述血液分离预处理芯片的入口流入，依次经过所述至少一个微柱阵列的截留和过滤，得到含有低于预设量的红细胞和血小板的血浆从所述血液分离预处理芯片的出口流出。本实用新型可以实现对极少量的血液样本的快速分离，提高血液样本的检测效率。
摘要（英）：

The utility model provides a blood separation pretreatment chip and blood separation apparatus, include and flow to at least one microtrabeculae array of arranging in proper order, every along blood the intercolumniation of microtrabeculae array is apart from all inequality, the intercolumniation of at least one microtrabeculae array apart from according to the order of at least one microtrabeculae array reduces in proper order, at least one microtrabeculae array includes at least that the red blood cell holds back the microtrabeculae array, it is right that the microtrabeculae array is held back to the red blood cell red blood cell in the blood is held back, in order to filter red blood cell in the blood, blood is followed the entry of blood separation pretreatment chip flows in, passes through in proper order holding back and filtering of at least one microtrabeculae array is contained the red blood cell of the volume of predetermineeing that is less than and the plasma of blood platelet and is followed the export of blood separation pretreatment chip is flowed. The utility model discloses the quickly separating to the blood sample of minute quantity can be realized, the detection efficiency of blood sample is improved.
