(FR) SYSTÈME, PROCÉDÉ ET PROGRAMME INFORMATIQUE DE MESURE DE PRESSION ARTÉRIELLE
Abstract
(EN)
There is provided a device (100) for use in measuring blood pressure. The device (100) comprises a light source (102) configured to emit light (104) onto the skin (106) of a subject (108). The light source (102) is configured to alternate between emitting coherent light and incoherent light. The device (100) also comprises a light detector (110) configured to detect light (104) scattered back from the skin (106) of the subject (108) and generate an electrical signal from the detected light. The generated electrical signal is for use in measuring a blood pressure of the subject (108).

La présente invention concerne un dispositif (100) servant à mesurer la pression artérielle. Le dispositif (100) comporte une source de lumière (102) configurée pour émettre de la lumière (104) sur la peau (106) d'un sujet (108). La source de lumière (102) est configurée pour alterner entre l'émission d'une lumière cohérente et d'une lumière incohérente. Le dispositif (100) comprend également un détecteur de lumière (110) configuré pour détecter la lumière (104) rétrodiffusée à partir de la peau (106) du sujet (108) et générer un signal électrique à partir de la lumière détectée. Le signal électrique généré est destiné à être utilisé dans la mesure d'une pression artérielle du sujet (108).
