摘要：
A fetal pulse oximetry probe (200) has clusters of light-transmissive bumps (100, 300) over the light source (110) and the light detector (120) on the surface of the probe. The probe is usually attached to the fetus's head. The clusters part the fetal hair and penetrate other light-attenuating organic materials on the head. The clusters thus transmit a more intense light signal. To reduce the amount of the signal shunting between them, the clusters also may be separated by additional opaque (light-shielding) bumps (190).
