摘要 |
<p>An intravaginal and intrauterine sensor for transillumination of a blood-perfused portion of fetal tissue to measure light extinction. The sensor comprises at least one light source (21, 23) and at least one photo-sensor (20, 22) with a shielding (30). The sensor may be mounted onto a paddle-shaped probe provided with signal connections (25, 26) contained in an insulated cable (27) leading to a measurement device. Alternatively, the sensor may include an opaque suction cup or other attaching apparatus for disposition on a protruding portion of the fetus. Most preferably, the sensor includes a housing.</p> |
