Title (EN) SYSTEMS AND METHODS FOR DETECTING EDEMA
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION D’UN ŒDÈME
Abstract:
(EN) System and method for detecting and monitoring edema in a patient are described. Initially, a patient's tissue is irradiated with light by a light source. A detector collects reflected light from the patient's tissue and generates data associated with the reflected light. A processing device receives the data and reflected light and calculates an intensity of the reflected light. The processing device then determined, based upon the intensity of the reflected light, whether the patient's tissue exhibits any symptoms of edema. Additionally, the processing device can compare a current intensity of the reflected light against historic information to monitor for any changes in a patient's edema level or severity.
(FR) La présente invention concerne un système et un procédé de détection et de surveillance de l'œdème chez un patient. Au départ, le tissu du patient est irradié avec de la lumière par une source lumineuse. Un détecteur collecte la lumière réfléchie par le tissu du patient et génère des données associées à la lumière réfléchie. Un dispositif de traitement reçoit les données et la lumière réfléchie et calcule une intensité de la lumière réfléchie. Le dispositif de traitement détermine ensuite, sur la base de l'intensité de la lumière réfléchie, si le tissu du patient présente des symptômes d'œdème. De plus, le dispositif de traitement peut comparer une intensité courante de la lumière réfléchie par rapport à des informations historiques pour surveiller tout changement de niveau ou de gravité d'œdème chez un patient.
