Title (EN) ANESTHESIA VAPORIZER AND METHOD
(FR) VAPORISATEUR D'ANESTHÉSIANT ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) Apparatus and method is disclosed for vaporizing a liquid anesthesia agent in a carrier gas for delivery to a patient such that the apparatus automatically establishes, monitors, and maintains a predetermined concentration level of the anesthesia agent in the carrier gas. The apparatus has an inlet and an outlet with a vaporization chamber therebetween, and a pump for dispensing small quantities of liquid anesthesia agent into the vaporization chamber. A first sensor senses the condition of the carrier gas upstream from the vaporization chamber and a second sensor senses the condition of the carrier gas/vaporized agent downstream from the vaporization chamber. A computer control system responsive to the sensors is configured to determine the concentration level of the agent delivered to the patient and to automatically increase or decrease the rate at which the pump is actuated to maintain the concentration level at the predetermined level.
(FR) La présente invention concerne un appareil et un procédé pour vaporiser un agent anesthésiant liquide dans un gaz porteur afin de l'administrer à un patient, de telle sorte que l'appareil établit, surveille et maintient automatiquement un niveau de concentration prédéfini de l'agent anesthésiant dans le gaz porteur. L'appareil comporte une entrée et une sortie avec une chambre de vaporisation entre elles, et une pompe pour distribuer de petites quantités d'agent liquide anesthésiant dans la chambre de vaporisation. Un premier capteur détecte l'état du gaz porteur en amont de la chambre de vaporisation et un second capteur détecte l'état du gaz porteur/de l'agent vaporisé en aval de la chambre de vaporisation. Un système de commande informatique réagissant à des capteurs est conçu pour déterminer le niveau de concentration de l'agent administré au patient et pour augmenter ou diminuer automatiquement la vitesse à laquelle la pompe est actionnée afin de maintenir le niveau de concentration au niveau prédéfini.
