Patent

CA 2675096

The invention relates to a calculation and control system for the determination of the state of a vascular access of a patient intended to follow successive sessions of extracorporeal blood treatment by extraction and return of the blood via the vascular access, the system comprising: means for determining the value of at least one hemodynamic extracorporeal parameter of the patient for at least two sessions; means for determining the value of the purification effectiveness of the treatment for at least two sessions; programmed means for determining a risk score relating to the state of the vascular access of the patient as a function of at least two values of the hemodynamic extracorporeal parameter and of at least two determined values of the purification effectiveness.

L'invention concerne un système de calcul et de commande permettant de déterminer l'état de l'accès vasculaire d'un patient devant subir des sessions successives de traitement sanguin extracorporel par extraction et retour du sang par l'accès vasculaire. Le système selon l'invention comprend : un moyen permettant de déterminer la valeur d'au moins un paramètre extracorporel hémodynamique du patient pour au moins deux sessions; un moyen permettant de déterminer la valeur de l'efficacité de purification du traitement pour au moins deux sessions; un moyen programmé permettant de déterminer un indice de risque correspondant à l'état de l'accès vasculaire du patient en fonction d'au moins deux valeurs du paramètre extracorporel hémodynamique et d'au moins deux valeurs déterminées de l'efficacité de purification.
