Abstract
Przedmiotem zgłoszenia jest układ do detekcji biomarkerów w powietrzu wydychanym z płuc pacjenta, zawierający szczelną komórkę wieloprzejściową wyposażoną we wloty i wylot gazu, do której wprowadzana jest próbka wydychanego powietrza za pomocą systemu pneumatycznego, przy czym komórka wieloprzejściowa wyposażona jest w jeden laser, którego wiązka światła skierowana jest współosiową drogą optyczną do komórki wieloprzejściowej, zawierającą co najmniej dwa równolegle ustawione wklęsłe zwierciadła, a także wlot i wylot gazów, która wypełniana jest próbką analizowanego wydychanego powietrza, przy czym system pneumatyczny połączony jest z wlotem i wylotem gazu komórki wieloprzejściowej przewodami doprowadzającymi wydychane powietrze, natomiast charakteryzujący się tym, że system pneumatyczny zawiera zbiornik wstępny powietrza wydychanego zawierający wlot powietrza i wylot powietrza, gdzie wylot powietrza dodatkowo posiada miernik przepływu powietrza, ponadto zbiornik wstępny połączony jest elastycznym przewodem doprowadzającym powietrze do komórki wieloprzejściowej z jednej strony oraz pompy, baratron a także wylotem powietrza z komórki wieloprzejściowej z drugiej strony zbiornika wstępnego. Przedmiotem zgłoszenia jest również sposób detekcji biomarkerów w powietrzu wydychanym z płuc pacjenta z wykorzystaniem układu.
