DEVICE FOR DETERMINING BLOOD COUNT Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: device comprises two photodetectors of which the one with d diameter of the light-sensitive flat is set at an angle of 90 deg to optical axis of the device while the other one lies on the axis coming out of the point of intersection of the device axis with the axis of a cylindrical tray lying in the plane which is perpendicular to the axis of the cylindrical tray and turned from the optical axis of the device through an angle not exceeding 120 deg. Diameter D of the photodetector light-sensitive flat is larger than the diameter d of said flat of the additional photodetector. EFFECT: improved design. 7 dwg
