BLOOD COLLECTION, PLASMA SEPARATION, AND HIGH PRECISION PLASMA DISPENSING DEVICE

摘要

The device consists of a syringe (1) with a plunger designed as a cup (2) large enough to contain a plasma separating thixotropic gel (5) and all the heavier parts of the blood. By centrifugation the gel plug has moved to cover the heavier parts of the blood, which is trapped in the plunger (2), leaving the plasma free in front to be dispensed from the syringe by advancing the plunger (2).
