Apparatus and method for platelet function and drug response testing based on microfluidic chip
First Claim
1. An apparatus to test a function and a drug response of a platelet based on a microfluidic chip, the apparatus comprising:
- a measuring device comprising sample containers containing a blood sample, a micro channel connecting the sample containers and configured to guide a shear flow of the blood sample, a measuring chamber connected to the micro channel at a center of the micro channel, and a sensor configured to measure aggregation and adhesion of a platelet generated in the measuring chamber; and
a fluid driving device connected to the measuring device and configured to generate a linearly reciprocating flow of the blood sample which is in the micro channel,wherein the aggregation and the adhesion of the platelet is generated in the measuring chamber while the blood sample reciprocately flows along the micro channel,wherein the micro channel is arranged in parallel with other micro channels, andwherein reagents which are different from each other are supplied in the measuring chamber.

Abstract
The present invention relates to an apparatus and a method for testing a function and a drug response of a platelet based on a microfluidic chip. The apparatus for test comprises a measuring device containing a blood sample and measuring aggregation and adhesion of a platelet generated by flow of the blood sample; and a fluid driving device which is connected to the measuring device and generates a oscillating shear flow of the blood sample. Therefore, activation of factors such as a platelet and von Willebrand factor (vWF) etc. can be activated uniformly and completely, and a repeatability of the platelet aggregation can be increased.
