Title
(EN) DRUG RESERVOIR FOR SEPARATE STORAGE OF SUBSTANCES
(FR) RÉSERVOIR DE MÉDICAMENT POUR LE STOCKAGE SÉPARÉ DE SUBSTANCES
Abstract
(EN) The present invention provides a drug reservoir (1) comprising a reservoir body (2) extending between an outlet end (4) and a proximal end (7), a front piston (8) arranged in a pre-use position within the reservoir body (2) between the outlet end (4) and the proximal end (7), a rear piston (9) arranged within the reservoir body (2) between the front piston (8) and the proximal end (7), a distal chamber (10) defined by the outlet end (4), a first portion of the reservoir body (2), and the front piston (8), the distal chamber (10) holding first contents (18), a proximal chamber (11) defined by the front piston (8), a second portion of the reservoir body (2), and the rear piston (9), the proximal chamber (11) holding second contents (12, 19) comprising a proximal liquid volume (19), and bypass means (3) allowing fluid flow past the front piston (8) in an advanced position of the front piston (8) in the reservoir body (2), wherein the second contents (12, 19) further comprises a proximal gas volume (12) lying within a volume range having a predetermined minimum value.
(FR) La présente invention concerne un réservoir de médicament (1) comprenant un corps de réservoir (2) s'étendant entre une extrémité de sortie (4) et une extrémité proximale (7), un piston avant (8) agencé dans une position de pré-utilisation à l'intérieur du corps de réservoir (2) entre l'extrémité de sortie (4) et l'extrémité proximale (7), un piston arrière (9) disposé à l'intérieur du corps de réservoir (2) entre le piston avant (8) et l'extrémité proximale (7), une chambre distale (10) définie par l'extrémité de sortie (4), une première partie du corps de réservoir (2), et le piston avant (8), la chambre distale (10) contenant un premier contenu (18), une chambre proximale (11) définie par le piston avant (8), une seconde partie du corps de réservoir (2), et le piston arrière (9), la chambre proximale (11) contenant un second contenu (12, 19) comprenant un volume de liquide proximal (19), et des moyens de dérivation (3) permettant l'écoulement de fluide au-delà du piston avant (8) dans une position avancée du piston avant (8) dans le corps de réservoir (2), le second contenu (12, 19) comprenant en outre un volume de gaz proximal (12) se situant dans une plage de volume ayant une valeur minimale prédéterminée.
