The invention relates to a sensor device as part of a measurement appliance with a measurement device for the measurement of vital parameters of a foetus during labor and delivery, in particular the oxygen content of the blood of the foetus. Such sensor devices should be applied to the tissue of the foetus in a secure and light-tight manner, and furthermore at least the carrier or sensor should be able to be fitted to the foetus gently and easily. According to the invention, the sensor device comprises a shell-type carrier, which is subdivided into an approximately centrally arranged attachment zone and a surrounding zone, which can be brought into contact with the tissue of the foetus, and the attachment zone is provided with a spiral-type attachment element for attaching the carrier to the leading part of the foetus, and the rotational axis of the attachment element is arranged approximately perpendicular to the surface of the carrier to be fitted to the leading part of the foetus. The surrounding zone comprises at least one light emitter and at least one receiver, whereby the attachment element is supported for rotation with respect to the surrounding zone.

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.
