Abstract

Przedmiotem zgłoszenia jest układ mikroprzepływowy do pobierania płynnych próbek, zwłaszcza krwi, za pomocą sił kapilarnych i ich rozdzielania przez wirowanie, obejmujący: pierwszą komorę (1) i drugą komorę (2) przy czym komory te połączone są przepływowo bezpośrednio ze sobą przez przewężenie (3); kapilarny kanał aspiracyjny (4) prowadzący do pierwszej komory (1), którego wlot (5) stanowi otwór w zewnętrznej powierzchni układu; kanał odpowietrzający (6), którego pierwszy koniec (7) stanowi inny otwór w zewnętrznej powierzchni układu. Wspomniane elementy układu mikroprzepływowego są tak umieszczone w tym układzie, że po umieszczeniu układu w rotorze wirówki celem wirowania bliżej osi obrotu znajdują się wlot kapilarnego kanału aspiracyjnego (5) i pierwszy koniec (7) kanału odpowietrzającego (6), dalej od osi obrotu znajduje się pierwsza komora (1), a najdalej od osi obrotu znajduje się druga komora (2). Układ ten charakteryzujący się tym, że drugi koniec (8) kanału odpowietrzającego (6) łączy się bezpośrednio z kapilarnym kanałem aspiracyjnym (4) wewnątrz układu, na odcinku między wlotem kanału aspiracyjnego (5) a pierwszą komorą (1), zaś pierwsza komora (1) jest konstrukcyjne przystosowana do tego, aby możliwy był dostęp do niej za pomocą standardowej końcówki do pobierania próbek, na przykład igły lub końcówki pipety automatycznej, i pobranie zawartości z wnętrza pierwszej komory (1).
