Title (EN) A PREFILLED INJECTION DEVICE WITH CLEANING CHAMBER
(FR) DISPOSITIF D'INJECTION PRÉREMPLI À CHAMBRE DE NETTOYAGE
Abstract:
(EN) The invention relates to a prefilled injection pen for apportioning multiple set doses of a liquid drug containing a preservative. The injection pen comprises a housing structure which permanently and non-removable secures a cartridge containing the preservative containing liquid drug. The cartridge is connected to a needle cannula which further has a sharp distal tip for penetrating the skin of a user. The distal tip of the needle cannula is concealed by an axially movable needle shield at least between injections. At the distal end of the axially movable needle shield, a cleaning chamber is provided which cleaning chamber contains a volume of the same preservative containing liquid drug as present in the cartridge. The cleaning chamber is further provided with an outlet which is open to the surroundings and through which outlet air and a quantum of the preservative containing liquid drug can escape. In the proximity of the outlet, means are provided to collect the escaped quantum of the preservative containing liquid drug.
(FR) L’invention concerne un stylo d’injection prérempli pour répartir des doses définies multiples d’un médicament liquide contenant un conservateur. Le stylo d'injection comprend une structure de boîtier qui fixe de façon permanente et non amovible une cartouche contenant le médicament liquide contenant un conservateur. La cartouche est reliée à une canule d'aiguille qui a en outre une pointe distale pointue pour pénétrer la peau d'un utilisateur. La pointe distale de la canule d'aiguille est dissimulée par une protection d'aiguille mobile dans le sens axial au moins entre des injections. Au niveau de l'extrémité distale de la protection d'aiguille mobile dans le sens axial, une chambre de nettoyage est prévue, laquelle chambre de nettoyage contient un volume du même médicament liquide contenant un conservateur tel que présent dans la cartouche. La chambre de nettoyage comporte en outre un orifice d'évacuation qui est ouvert vers l'extérieur et à travers lequel l'air et un quantum du médicament liquide contenant un conservateur peuvent s'échapper. À proximité de l'orifice d'évacuation, des moyens sont prévus pour collecter le quantum du médicament liquide contenant un conservateur s'étant échappé.
