  • Patent number: 9239325
    Abstract: There is provided a microchip-based platelet multi-function test apparatus. The apparatus includes a sample container configured to accommodate a blood sample therein, a stirrer that is installed inside the sample container and induces a shear flow in the blood sample, a parallel channel configured to divide and flow the blood stirred by the stirrer into a plurality of paths, a vacuum device that is connected to an end of each parallel channel, maintains constant pressure, allows the stirred blood to flow along the parallel channel, a light source that is installed in a rear side of the parallel channel and radiates light to the parallel channel, and an image sensor that receives light transmitted through the blood in the parallel channel, converts the light into an electrical signal, and measures a flowing distance of a blood flow.

  • Patent number: 8772040
    Abstract: An apparatus and method for platelet multi-function analysis using measurement of electrical characteristics, and a stirring microchip are provided. The apparatus for platelet multi-function analysis includes a stirring microchip that has a sample storage chamber formed therein to hold a blood sample, and in which an inner part of the sample storage chamber is coated with reagents composed of collagen and epinephrine, or collagen and ADP. The apparatus for platelet multi-function analysis further includes a microstirrer installed inside the stirring microchip to stir the blood sample and the reagents in the stirring microchip and a stirring induction unit configured to facilitate stirring of the microstirrer. Therefore, the platelet aggregation and multi-function analysis can be performed using a trace of blood, and the platelet aggregation and multi-function analysis can also be performed using the whole blood taken from the veins through a vacuum tube containing an anticoagulant.
