Title (EN) DEVICES AND METHODS FOR IMPROVING ACCURACY OF FLUID DELIVERY
(FR) DISPOSITIFS ET PROCÉDÉS PERMETTANT D’AMÉLIORER LA PRÉCISION D’UN APPORT DE LIQUIDE
Abstract:
(EN) Devices and methods for delivering therapeutic fluid to a patient's body are described. The devices may comprise a dispensing unit having a reservoir, a driving mechanism having a movable member for delivering therapeutic fluid to a patient's body, at least one sensor for sensing a relative position of the movable member and generating a signal, and a processor for controlling the driving mechanism to deliver an amount of therapeutic fluid that compensates for a change in the flow of the therapeutic fluid occurring during fluid delivery. The methods may be implemented by operating the driving mechanism, receiving a signal based on the position of the movable member, determining an amount of therapeutic fluid to deliver, and controlling the driving mechanism to deliver an amount of fluid that compensates for a change in flow occurring during fluid delivery.
(FR) La présente invention concerne des dispositifs et des procédés d’apport de liquide thérapeutique dans le corps d’un patient. Lesdits dispositifs peuvent comprendre les éléments suivants : une unité de distribution qui présente un réservoir ; un mécanisme d’entraînement doté d’un élément amovible destiné à l’apport d’un liquide thérapeutique dans le corps d’un patient ; au moins un capteur permettant de détecter une position relative de l’élément amovible et de générer un signal ; et un processeur permettant de contrôler le mécanisme d’entraînement distribuant une quantité de liquide thérapeutique, qui compense un changement de débit du liquide thérapeutique se produisant lors de la distribution du liquide. Les procédés de la présente invention peuvent être mis en œuvre par l’actionnement du mécanisme d’entraînement, la réception d’un signal en fonction de la position de l’élément amovible, la détermination d’une quantité de liquide thérapeutique à distribuer, et le contrôle du mécanisme d’entraînement visant à distribuer une quantité de liquide, qui compense un changement du débit se produisant lors de l’apport du liquide.
