Zusammenfassung:FIELD: medical engineering. ^ SUBSTANCE: device has optically connected optical radiation source, light division unit, light guide and photodetector. Photodetector output is connected to video monitor, light guide end for transmitting optical radiation is removably set in medical needle pavilion. Polished light guide end is combined with needle end and manufactured at an angle of alpha determined from relation of arc sin (1/n2)< alpha < arc sin (n1/n2), where n2 is the light guide material refraction coefficient value and n1 is the epidural space tissue refraction coefficient value. ^ EFFECT: high accuracy of examination. ^ 2 dwg
