Abstract
(EN)
The present invention relates to a blood flow measuring apparatus and method having a function of correcting noise due to pressure, the apparatus comprising: a light source module configured to come into contact with tissue so as to emit light thereat; a detection module for detecting the light emitted at the tissue; a pressure measurement module configured to measure pressure applied to the tissue; and a signal processing unit for processing a signal received from the detection module by applying a correction function to the signal such that noise, which is generated according to the pressure applied when light is detected, can be corrected. A blood flow measuring apparatus and method having a function of correcting noise due to pressure, according to the present invention, can improve accuracy and reliability since the effect of noise, which is generated according to a change in pressure, can be removed from detected data.

La présente invention concerne un appareil et un procédé de mesure de débit sanguin à fonction de correction du bruit dû à la pression, l'appareil comprenant : un module de source de lumière conçu pour entrer en contact avec un tissu de façon à émettre de la lumière au niveau de ce dernier ; un module de détection pour détecter la lumière émise au niveau du tissu ; un module de mesure de pression conçu pour mesurer une pression appliquée au tissu ; et une unité de traitement de signal pour traiter un signal reçu du module de détection par application d'une fonction de correction au signal de sorte que le bruit, qui est produit en fonction de la pression appliquée lorsque la lumière est détectée, puisse être corrigé. L'appareil et le procédé de mesure de débit sanguin à fonction de correction du bruit dû à la pression, selon la présente invention, permettent d'améliorer la précision et la fiabilité étant donné que l'effet du bruit, qui est produit en fonction d'un changement de pression, peut être supprimé des données détectées.
