Inventor: WAIGH ROGER DAVID
IPC: A61K49/00
Filed: 1991-03-21
Abstract: Procédé d'examen de tissus corporels internes au moyen de procédés d'imagerie à résonance magnétique nucléaire et, particulièrement, d'examen des voies digestives en administrant au sujet à examiner un polymère silico-organique inerte et riche en protons comme moyen de contraste. Le polymère est, de préférence, un polysiloxane, spécialement un polydiméthylsiloxane. On peut l'administrer facilement en émulsion et il est inerte, non-toxique et n'est pas absorbé ou dégradé dans le corps humain. Il résoud les inconvénients des techniques connues qui utilisent un agent contrastant ou opacifiant impliquant l'introduction d'un dérivé métallique, ce qui peut présenter des effets secondaires indésirables. On peut l'utiliser sans avoir recours aux techniques d'amélioration d'image (comme dans un équipement à résonance magnétique nucléaire plus ancien) ainsi qu'avec un équipement plus moderne. Le procédé peut produire des résultats d'image conséquents et de bonne qualité et s'utiliser comme procédé de diagnostic partiel dans l'examen de tissus et de cavités corporelles internes de texture souple, étant donné qu'il produit un contraste sélectif du contenu des voies digestives (par exemple, le colon, le duodénum et d'autres parties des voies digestives).

Abstract: The invention relates to a method for autoclaving porous, lumpy materials by means of pressurised steam, the autoclaving process comprising, successively, a steam-operated heating phase, a holding phase and an expansion phase for pressure and temperature, the holding phase comprising a drying process in which the autoclave, going beyond compensating for heat losses and being set to a temperature above the evaporation temperature of the water, is heated indirectly and the material is dried by a controlled blowing-off of steam-containing heating medium from the interior of the autoclave. In order to obtain as dry a product as possible using as little energy as possible, it is provided that the drying process essentially extends over the entire holding phase, one or more autoclaves in the holding phase being supplied with sufficient heat for the steam necessary for a heating phase to be blown off and, after previous intermediate storage if appropriate, used to operate a heating phase. <IMAGE>
