Abstract
A sensor device used as part of a measurement device with a measurement unit for measuring vital parameters of a fetus during labor and delivery. The sensor is attached to the presenting part of the fetus for the duration of labor and delivery. In order to prevent the arterial blood flow in the fetal tissue at the measurement point from being impaired by attachment of the sensor to the fetal tissue, the sensor has an approximately round, curved cup which forms a concavity on its concave side and is subdivided into an attachment zone at the center and an elastic peripheral zone surrounding it where the light emitter and receiver are arranged, whereby the peripheral zone of the cup attached to the fetal tissue rests in a flexible, spring-loaded manner on the fetal tissue.
