  • the gynaecologist and the obstetrician can follow, measure and enlarge many parameters, among which those tactile perceptions that they could directly perceive putting their hands on the pregnant abdomen, following the uterine contractions course; they can also detect the fetal hypoxia status, the fetus heart rate and the mother's one, the skin surface temperature and so on.
  • This is a system that improves the family of instruments used at present for the diagnosis described through images (or clinical imaging) (TAC, Magnetic Resonance, Echography, Thermography, Angiography, etc.).

  • the instruments used at present to monitor the last steps of the labour can be retraced in: Toeographics instruments, to determine the uterine pressure and the kind of contractions: they have the limit to detect the pressure only on a little area of the abdomen and the needed of an elastic bend.
  • Cardiographs to determine the fetal heart rate they are based on the use of ultrasounds, reproducing the fetal heart rate, but actually they don't reproduce the real ECG that should allow the fetal hypoxia status identification.
  • Transvaginal probes (some electrodes put on the fetus scalp needed): they allow the detection of fetal pulsed oximetry. These invasive methods, are really uncomfortable and they can cause internal infections.
  • The'lntegrated Pregnancy Monitoring Unit is a system that allows to perceive different parameters from the abdominal surface of a pregnant woman, to provide objective and measurable parameters shown through very intelligible images, which can be recorded, analyzed and compared with reference models and with other images prerecorded of the same patient.

  • One of the sensors is placed on another part of the body to detect a sync signal for a best reliability and precision in the uterine contractions measurement.
  • the [A] subsystem also, includes a [C] device which electrically feeds the sensors/transducers, elaborats the received data and transmits the results to the [B] subsystem, through wire, or wireless transmission system.

  • This instrument uses, as computing unit and graphic representation, a standard personal computer with standard de facto operating systems and softwares. Computing, interface data systems and transmission use common microprocessors and widely used electronic standard systems.
  • a model of the [B] subsystem also works as a "Holter” and it is able to engage or transmit "warning" signals to an operator when some parameters values exceed predefined limits, such as parts of the body temperature, of the heart rate, of the frequency and/or the intensity of the uterine contractions, of the fetal hypoxia status.

Abstract

L'invention concerne une unité intégrée de surveillance de grossesse formant un système capable de surveiller et de montrer, même graphiquement, des phénomènes détectables par des paramètres physiques et chimiques (pression, température, humidité, pH, voltages électriques, etc.) à la surface d'un corps élastique - plastique, vivant ou inerte. Le système a été construit pour donner au gynécologue la possibilité de suivre les diverses étapes du travail, afin de déterminer la fréquence, l'intensité et la durée des contractions, et leur relation avec les paramètres de dépistage de la santé du fœtus et de l'état de fatigue de la femme. Le présent système imite, agrandit et rend objectives les perceptions qui sont détectables par une main médicale experte. Le système sonde les perceptions dans le temps et l'espace, il les montre en 2D/3D et connecte les valeurs ensemble. Le présent instrument peut être utilisé dans plusieurs applications et peut prendre des formes et des dimensions en fonction des paramètres et du corps à surveiller.
