Title
(EN) DEVICES AND METHODS FOR DELIVERY OF SUBSTANCES WITHIN A PREFILLED SYRINGE
(FR) DISPOSITIFS ET PROCÉDÉS DE DISTRIBUTION DE SUBSTANCES DANS UNE SERINGUE PRÉ-REMPLIE
Abstract
(EN)
An apparatus includes a housing, a carrier, a medicament container, and a flexible member. The housing defines an opening placing a gas chamber of the housing in fluid communication with an exterior volume. The carrier has a proximal surface that defines a portion of the gas chamber. The medicament container is coupled to the carrier and has a distal end portion coupled to a delivery member. The medicament container containing a medicament and includes an elastomeric member that seals the medicament therein. The flexible member has a distal end portion coupled to the elastomeric member and a proximal end portion coupled to a valve member. The flexible member transitions from a collapsed configuration to an expanded configuration when the elastomeric member moves within the medicament container. The flexible member moves the valve member relative to the opening when the flexible member transitions from the collapsed configuration to the expanded configuration.

La présente invention a pour objet un appareil comportant un boîtier, un support, un récipient de médicament et un élément flexible. Le boîtier définit une ouverture permettant de placer une chambre à gaz du boîtier en communication fluidique avec un volume extérieur. Le support a une surface proximale qui définit une partie de la chambre à gaz. Le récipient de médicament est couplé au support et a une partie d'extrémité distale couplée à un élément de distribution. Le récipient de médicament contenant un médicament comprend un élément élastomère qui scelle le médicament en son sein. L'élément flexible a une partie d'extrémité distale couplée à l'élément élastomère et une partie d'extrémité proximale couplée à un élément de valve. L'élément flexible passe d'une configuration repliée à une configuration déployée lorsque l'élément élastomère se déplace à l'intérieur du récipient de médicament. L'élément flexible déplace l'élément de valve par rapport à l'ouverture lorsque l'élément flexible passe de la configuration repliée à la configuration déployée.
