Title (EN) IRRIGATION SYSTEM
(FR) SYSTEME D'IRRIGATION
Abstract:
(EN) An irrigation system for use in arthroscopic surgery including a variable RPM pump for introducing irrigation fluid from a fluid supply to a body irrigation site, a pressure control valve in the outflow from the irrigation site, a pressure sensor and associated controller for sensing pressure at the site and adjusting the pressure control valve for maintenance of the pressure within predetermined parameters, an override controller responsive to an inability to maintain pressure within the set parameters and responsive thereto to vary the flow rate of the pump, and associated display and signal components. The flow rate and pressure are individually and independently controllable.
(FR) Système d'irrigation destiné à être utilisé en chirurgie arthroscopique comprend une pompe à vitesse variable permettant d'introduire, depuis une alimentation en fluide, un fluide d'irrigation dans un site d'irrigation du corps, une soupape de commande de pression située dans l'écoulement provenant du site d'irrigation, un capteur de pression et une unité de commande associés permettant de détecter la pression au niveau du site et régler la soupape de commande de pression afin de maintenir la pression dans les paramètres prédéterminés, une unité de commande de dérogation réagissant à une incapacité de maintenir la pression dans les paramètres fixés et faisant varier le débit de la pompe, ainsi que des composants associés d'affichage et de signalisation. Le débit et la pression peuvent être commandés individuellement et indépendamment.
