Abstract

L'invention concerne un procédé et un système de détection et de neutralisation de caillots sanguins lors d'une dialyse (par exemple, une hémodialyse). Un capteur à fibre optique est disposé dans une machine d'hémodialyse pour détecter des vibrations de cellules sanguines, et la machine d'hémodialyse peut être conçue pour empêcher la coagulation du sang en faisant sonner une alarme, en agitant les cellules sanguines, en réalisant une perfusion de sérum physiologique, en augmentant la température et/ou en réalisant une perfusion d'héparine.
