Abrégé
(EN)
A drug delivery device comprising a housing (1) with a drug container (2) being provided with delivering means comprising a piston (5) for expelling a drug (4) from the drug container (2). The housing (1) further comprising a displaceable piston rod (6) abutting the piston (5) of the drug container (2) and rotating means being in engagement with the piston rod (6), said rotating means being provided with a one-way mechanism. The one-way mechanism comprises a helical spring (12) wound tightly around an axle (11), one end of said helical spring (12) being fixed in relation to the housing (1), the other end of the helical spring (12) being in a free state.
(FR)
L'invention se rapporte à un dispositif d'administration de médicament comportant un logement (1) ayant un contenant (2) pour médicament doté d'un organe d'administration comprenant un piston (5) permettant l'expulsion d'un médicament (4) à partir dudit contenant (2). Le logement (1) comporte par ailleurs un tige de piston mobile (6) en position d'aboutement avec le piston (5) du contenant pour médicament et un organe de rotation accouplé à la tige de piston (6), ledit organe de rotation étant doté d'un mécanisme unidirectionnel. Ce mécanisme unidirectionnel comporte un ressort hélicoïdal (12) enroulé étroitement autour d'un axe (11), une extrémité dudit ressort hélicoïdal (12) étant fixée par rapport au logement (1) et l'autre extrémité du ressort hélicoïdal (12) étant dans un état libre.
