FIELD: medical engineering. SUBSTANCE: oximeter comprises a module for registering radiation dispersed in blood, an optical connector with radiators, photodetector and preamplifier. The end of a fiberoptic bundle facing the tray is gathered from monofibers so that its longitudinal axis of symmetry lies in a common plane with the tray axis and makes an angle of 30-50 deg with its perpendicular to the tray axis lying in the same plane. d/D ≪ 1 where d bundle diameter; D tray diameter. EFFECT: improved design. 3 dwg
