Title (EN) DEVICE AND METHOD FOR REAL-TIME MEASUREMENT OF PARAMETERS OF MECHANICAL STRESS STATE AND BIOMECHANICAL PROPERTIES OF SOFT BIOLOGICAL TISSUE
(FR) DISPOSITIF ET PROCÉDÉ DE MESURE EN TEMPS RÉEL DES PARAMÈTRES D'UN ÉTAT DE CONTRAINTE MÉCANIQUE ET DES PROPRIÉTÉS BIOMÉCANIQUES D'UN TISSU BIOLOGIQUE MOU
Abstract:
(EN) A device and a method for simultaneous recording, in real time, of the parameters characterising the mechanical tension, elasticity, dynamical stiffness, creepability and mechanical stress of soft biological tissue is provided. By means of the myometer, a constant external pre-pressure is created, independently of the device's position, between the tissue and the testing end of the device. Next, the tissue is subjected to a short-term external dynamic influence. The mechanical change in the shape of the tissue and its mechanical response are registered as a graph of the tissue's oscillations. For calculating the parameters, the time span on the graph is used which involves the oscillation period from the beginning to the end of the effect on the tissue plus its subsequent first 1.5 self-oscillation period. Invention enables recording and data-processing to be carried out simultaneously as well as statistically significant estimates to be made in real time.
(FR) La présente invention concerne un dispositif et un procédé d'enregistrement simultané, en temps réel, des paramètres caractérisant la tension mécanique, l'élasticité, la rigidité dynamique, l'aptitude à la déformation et la contrainte mécanique d'un tissu biologique mou. Une pré-pression externe constante est créée à l'aide du myomètre, indépendamment de la position du dispositif, entre le tissu et l'extrémité de test du dispositif. Le tissu est ensuite soumis à une influence dynamique externe à court terme. La modification mécanique de la forme du tissu et sa réponse mécanique sont enregistrées sous la forme d'un graphique des oscillations du tissu. Pour calculer les paramètres, un intervalle de temps sur le graphique est utilisé qui implique la période d'oscillation du début à la fin de l'effet sur le tissu plus sa première période d'auto-oscillation de 1,5 subséquente. L'invention permet de réaliser l'enregistrement et le traitement de données simultanément et permet également de faire des estimations statistiquement significatives en temps réel.
