Title
(EN) REFILL SYSTEM FOR MEDICAL DEVICE USING JET DELIVERY PRINCIPLE
(FR) SYSTÈME DE RECHARGE POUR DISPOSITIF MÉDICAL FAISANT INTERVENIR UN PRINCIPE DE DISTRIBUTION PAR JET
Abstract
(EN)
A fluid injection device of the jet stream type, comprising: - a housing defining a fluid collection chamber and having a nozzle; - a coupler for coupling the fluid injection device with a fluid container; - a piston head configured to be received and movable in the housing, to increase and decrease a volume thereof; - a piston rod, coupled to the piston head and having an internal flow channel, which extends from the piston rod for penetration of the fluid container, the piston head including a valve made of an elastically deformable material and comprising a radial flow channel, the radial flow channel being open when the piston head is moved in a fluid collection chamber volume increasing direction and the radial flow channel being closed by an elastic deformation of the valve material when the piston head is moved in a fluid collection chamber volume decreasing direction.
(FR)
L'invention concerne un dispositif d'injection de fluide du type à jet, comprenant : - un boîtier définissant une chambre de collecte de fluide et comprenant une buse ; - un coupleur pour raccorder le dispositif d'injection de fluide à un récipient de fluide ; - une tête de piston conçue pour être reçue et être mobile dans le boîtier, afin d'augmenter et de diminuer son volume ; - une tige de piston, accouplée à la tête de piston et comportant un canal d'écoulement interne, qui s'étend à partir de la tige de piston pour pénétrer dans le récipient de fluide, la tête de piston comprenant une valve constituée d'un matériau élastiquement déformable et comprenant un canal d'écoulement radial, le canal d'écoulement radial étant ouvert lorsque la tête de piston est déplacée dans une direction d'augmentation du volume de la chambre de collecte de fluide et le canal d'écoulement radial étant fermé par une déformation élastique du matériau de valve lorsque la tête de piston est déplacée dans une direction de diminution du volume de la chambre de collecte de fluide.
