Abstract: The invention relates to a device for long-term recording of strong magnetic fields. This device comprises a magnetic field sensor as well as an analyser unit that forms signals characterising the effects of the magnetic fields from the sensor signals by integration or differentiation, and that stores these signals optionally in a memory or displays, by means of a signalling unit, that a limit has been exceeded.

Abstract: A probe for physiological pressure measurement in a human or animal body comprises a probe head, a line such as a catheter, and a pressure transducer, particularly an electric transducer, in the probe head. For measuring pressure, the probe head with the pressure transducer is disposed at a measuring site for pressure measurement, with the probe head being adapted for connection to an analyzer and display unit via the line. A counter or controller means is provided for recording a number of operational applications of the probe.

Abstract: The invention relates to a device for processing the signals of medical sensors for display or interpretation, respectively, in data monitors. The sensor signals are initially scaled or corrected, respectively, by means of an active circuit and are stored if and when necessary. The signals so corrected are then signalled to the data monitor by means of a bridge simulator or supplied to a correction circuit that corrects the signals of the sensor as such by feeding additional voltages or currents, respectively, or also by connecting further impedance elements.

Abstract: Arrangement for determining the oxygen saturation in human blood vessels and organs with a measurement sensor with at least two light sources of different wavelengths--preferably wavelengths of 660 nm and 940 nm--and with at least one receiver which receives the light transmitted and reflected from the oxygen particles which are bonded with the hemoglobin in the irradiated vessel or organ and transmits it as an electrical signal to a pulsoximeter for evaluation of the measurement results and readout on a display device. An additional measurement sensor is associated with the measurement sensor for locating a blood vessel or organ to be selected and the two measurement sensors are designed such that they can be handled together as a constructional unit.

Abstract: An apparatus for measuring the oxygen saturation of fetuses during childbirth, using a probe, assigned to the fetal scalp, with two or four photodiodes operating at different wave lengths and a photodetector disposed in the plane of the photodiodes as parts of an optical reflection measurement portion for determining the oxygen saturation in the arterial or pulsating bloodstream, which is proportional to the ratio of oxyhemoglobin to the sum of oxyhemoglobin and desoxyhemoglobin by reflection measurement in an area, which is not subjected to a partial vacuum. Output signals of the apparatus are supplied to an evaluating pulsoxymeter over a cable connection having a plug-and-socket connector.
