A fluid delivery system that includes an infusion pump and a cassette (1) with tubing (75) that is configured for en-gaging the pump mechanism of the infusion pump to accurately and repeatably deliver a fluid to a subject. The cassette has a housing with first and second ends for holding flexible tubing through which the fluid is directed, and the tubing engages a pump-ing mechanism to provide movement of the fluid through the tubing. When engaged with the pumping mechanism, the length of tubing is accurately and repeatably positioned in contact with and between the curved wall and the pumping mechanism.

L'invention porte sur un système de distribution de fluide comprenant une pompe d'infusion et une cassette (10) munie d'une canalisation (75), configurée pour engager le mécanisme de pompe de la pompe d'infusion de façon à administrer de façon précise et répétée un fluide à un sujet. La cassette comporte un boîtier présentant des première et seconde extrémités destiné à contenir une canalisation souple dans laquelle le fluide est dirigé, et la canalisation engage un mécanisme de pompage afin d'appliquer un mouvement au fluide dans la canalisation. Lorsqu'elle est engagée avec le mécanisme de pompage, la longueur de canalisation est positionnée de façon précise et reproductible en contact avec et entre la paroi incurvée et le mécanisme de pompage.
