Title (EN) METHOD FOR DETECTION AND DISPLAY OF EXTRAVASATION AND INFILTRATION OF FLUIDS AND SUBSTANCES IN SUBDERMAL OR INTRADERMAL TISSUE
(FR) PROCEDE POUR DECELER ET VISUALISER L'EXTRAVASATION ET L'INFILTRATION DE FLUIDES ET DE SUBSTANCES DANS UN TISSU SOUS-CUTANE OU INTRADERMIQUE
Abstract: front page image
(EN)A method for the real-time visualization and detection of extravasated and or infiltrated fluid and substances, including blood, that occur near the cannulation site of an injection is described wherein illumination or transillumination with near infrared light is used to image the contrast in real-time between absorbing and nonabsorbing subdermal and intradermal structures of blood vessels and remaining surrounding tissue, foreign substances and other structures in order to establish a baseline image of the body area of interest, and any new image is monitored and compared with the baseline image to detect the extravasation and/or infiltration of fluids and substances, including blood, around a vein or artery into the subdermal or intradermal tissue.
(FR)L'invention concerne un procédé pour visualiser et déceler en temps réel la présence de fluides ou de substances extravasés et/ou infiltrés, y compris le sang, à proximité du site de canulation d'une injection. Selon l'invention, on utilise l'éclairage ou la transillumination à la lumière proche de l'infrarouge pour visualiser le contraste en temps réel entre l'absorption et la non absorption de structures sous-cutanées et intradermiques de vaisseaux sanguins et de tissus environnants restants, des substances exogènes et d'autres structures, afin d'élaborer une image de ligne de base de la zone corporelle concernée. Toute nouvelle image est surveillée et comparée à l'image de ligne de base pour déceler une extravasation et/ou une infiltration de fluides et de substances, y compris le sang, autour d'une veine ou d'une artère dans le tissu sous-cutané ou intradermique.
