    Patent number: 5361759
    Abstract: A system for in vivo monitoring of the presence and concentration of meconium and/or blood in amniotic fluid during labor by spectral analysis includes a probe for insertion in the uterus, the probe having a flexible body housing an optical cell. The probe has at least one aperture so that amniotic fluid can enter the cell. A fiber optic cable connects the cell to a light source and to a spectral analyzer, and the probe includes structure for shielding the fiber optic cable from any light scattered by the wall of the uterus or fetus.
