Abstract

The invention provides a blood separation pretreatment chip and a blood separation device. The pretreatment chip includes at least one microcolumn array arranged along the blood flow direction in order, column spacings between the microcolumn arrays are different, the column spacing of the at least one microcolumn array decreases successively according to the arrangement order of the at least one microcolumn array, and the at least one microcolumn array at least includes a red blood cell intercepted microcolumn array, the red blood cell intercepted microcolumn array intercepts red blood cells in blood to filter out red blood cells from the blood. Blood flows in from an inlet of the blood separation pretreatment chip, and undergoes interception and filtration by the at least one microcolumn array in order, thus obtaining blood plasma containing red blood cells and platelets with the amount being lower than a preset amount, and the obtained blood plasma then flows out from a blood separation pretreatment chip outlet. The blood separation pretreatment chip and the blood separation device provided by the invention can realize fast separation of a small amount of blood samples, and improve the blood sample detection efficiency.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of biomedicine, and in particular relate to a blood separation pretreatment chip and a blood separation device. Background technique [0002] During the treatment of cancer patients, the quality of the treatment can be measured by the response results of various marker molecules (such as protein, miRNA (MicroRNA, non-coding single-stranded RNA molecule)) in the blood. Usually, a blood tester is used to detect the blood samples of cancer patients, which can realize non-destructive detection of cancer patients, monitor the patient's condition in real time, provide an important basis for doctors to adjust reasonable treatment plans in time, and provide accurate medical testing. solid foundation. [0003] However, in addition to biomolecules such as proteins and miRNAs, blood also contains a large number of cells of different sizes. In order to improve the detection sensitivity and re...
