  • Patent number: 9983220
    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.

  • Patent number: 9927425
    Abstract: The present invention relates to an apparatus and method for testing a multi-function and a drug response of platelet based on a centrifugal microfluidics. The testing apparatus according to the present invention may include: a rotatable disk; a sample chamber arranged at the center of the disk such that a blood sample is accommodated therein; stirring chambers respectively connected to the sample chamber in multiple radial directions so as to introduce a shear flow in the blood sample; microchannels connected to the stirring chambers such that adhesion and cohesion of platelets occur during the movement of the blood sample; and a waste sample chamber in which the blood sample is accommodated after passing through the microchannels. According to the present invention, multiple drug tests can be performed on a single blood sample at one time in multiple channels such that multiple tests is possible with respect to complex platelet functions, and thus testing time is reduced and testing costs can be saved.

  • Publication number: 20070105236
    Abstract: A method of examining blood type and an apparatus for examining blood type using the method are presented. According to the method, the blood type is examined once the blood is injected into the apparatus, and the result of examination is kept safely. The method comprises introducing the reagents into the plural reagent chambers respectively; flowing the blood into each of reagent chambers and mixing them with the reagents; filtering the mixture of blood; and flowing the mixture of blood which passed the filters-into the reading channels. The introduced blood is passed the micro channels and reacted with the reagents, and the results are obtained from filtering the mixture of blood. Thus, even small quantity of blood may be examined easily and clearly. Further, the results of examination are easily read and kept. The apparatus may be carried out and used with convenience.
