Device for treating peripheral blood to obtain quantitative plasma and application

The invention provides a device for treating whole blood or peripheral blood to obtain quantitative plasma and application, and can achieve trace, rapid and convenient collection of the quantitative plasma of the whole blood or the peripheral blood. The device comprises an anticoagulation capillary tube, and is characterized in that one end of the capillary tube is a blood sampling end, the capillary tube is provided with a sampling scale line at a position which is 90 mu L away from the blood sampling end, and scratches at positions of 50 mu L and 80 mu L; the device further comprises a capillary centrifuge and a silica gel plug, and the silica gel plug is detachably connected to the blood sampling end and used for blocking the blood sampling end. The device can successfully replace milliliter-level venous blood sampling, has better correlation with a detection result of an original detection kit, and can be applied to whole blood or peripheral blood trace blood sampling detection, sothat many people such as
