This reconstitution and injection system delivers a drug in solution under pressure, and injects powdered or lyophilized drugs that require reconstitution, rehydration or dilution. In one embodiment, the system includes a syringe having a barrel, a plunger, a handle, a pump and a channel communicating the barrel with an injection needle. The pump pushes a liquid from the barrel through the injection needle via the channel upon fluid communication between the barrel and the injection needle for delivery of the liquid. In another embodiment, the system includes a first port receiving a syringe, a second port receiving a drug vial, a channel providing communication between the first and second ports, and a controller permitting or inhibiting fluid communication between the first and second ports. In yet another embodiment, the system includes an actuator and a housing having a channel providing fluid communication between a reservoir and the injection needle.

L'invention concerne un système de reconstitution et d'injection conçu pour administrer un médicament en solution sous pression, et pour injecter des médicaments en poudre ou lyophilisés nécessitant une reconstitution, une réhydratation ou une dilution. Dans un mode de réalisation, le système comprend une seringue composée d'un cylindre, d'un piston, d'une poignée, d'une pompe et d'un canal reliant le cylindre à une aiguille d'injection. La pompe pousse un liquide depuis le cylindre à travers l'aiguille d'injection via le canal par communication fluidique entre le cylindre et l'aiguille d'injection de manière à administrer ledit liquide. Dans un autre mode de réalisation, le système comprend un premier port recevant une seringue, un second port recevant un flacon, un canal permettant la communication entre le premier port et le second port, et un dispositif de commande permettant ou empêchant la communication fluidique entre les premier et second ports. Dans un autre mode de réalisation, le système comprend un actionneur et un logement pourvu d'un canal permettant la communication fluidique entre un réservoir et l'aiguille d'injection.
