Title
(EN) CASSETTE FOR DIFFERENTIAL PRESSURE BASED MEDICATION DELIVERY FLOW SENSOR ASSEMBLY FOR MEDICATION DELIVERY MONITORING AND METHOD OF MAKING THE SAME
(FR) CASSETTE POUR ENSEMBLE DE CAPTEUR DE DÉBIT D’ADMINISTRATION DE MÉDICAMENT BASÉE SUR LA PRESSION DIFFÉRENTIELLE  POUR CONTROLLER L’ADMINISTRATION DE MÉDICAMENT ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) A disposable assembly for use with a sensor assembly, and method for making the same, the disposable comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned along the fluid flow passage between the inlet and the outlet. The fluid pressure membrane is at a location in the fluid flow passage between the inlet and the outlet. The fluid pressure membrane defines an opening for receiving the flow restricting element. The fluid pressure membrane is located between the lid portion and the base portion of the body.
(FR) La présente invention concerne un ensemble jetable destiné à être utilisé avec un ensemble de capteur, et son procédé de fabrication. L’ensemble jetable comporte un corps, un élément de limitation de débit, et une membrane hydraulique. Le corps comprend une partie de couvercle et une partie de base. Le corps définit un passage d’écoulement de fluide qui forme un orifice d’entrée et un orifice de sortie. L’élément de limitation de débit est positionné le long du passage d’écoulement de fluide entre l’orifice d’entrée et l’orifice de sortie. La membrane hydraulique se trouve à un emplacement dans le passage d’écoulement de fluide entre l’orifice d’entrée et l’orifice de sortie. La membrane hydraulique définit une ouverture pour recevoir l’élément de limitation de débit de fluide. La membrane hydraulique est située entre la partie de couvercle et la partie de base du corps.
