The invention relates to an injection apparatus comprising a housing (42) designed for receiving a container (50) containing a liquid. An axially sliding member (92) which is received in the housing (42) is used to act upon said container (50). An actuating member (174) is used to influence the position of the axially sliding member (92) relative to itself. An element (144) is placed in the housing (42) in such a way that it can slide axially but is substantially rotatively-blocked relatively to the housing (42). The actuating member (174) can take at least two different positions relatively to said element (144). In a first position (Fig. 12), it can rotate relatively to said element (144) and in a second position (Fig. 13), it is rotatively blocked relatively to said element (144). The invention also relates to a method for reconstituting an injection fluid and a method for performing an injection.
L'invention concerne un appareil d'injection comportant un boîtier (42) conçu pour recevoir un contenant (50) renfermant un liquide. Un élément (92) coulissant axialement, logé dans le boîtier (42), sert à agir sur ledit contenant (50). Un élément d'actionnement (174) a pour fonction d'influer sur la position, par rapport à lui, de l'élément coulissant axialement (92). Un élément (144) est placé dans le boîtier (42) de manière à pouvoir coulisser axialement mais de manière à être pratiquement bloqué en rotation, par rapport au boîtier (42). L'élément d'actionnement (174) peut prendre au moins deux positions différentes par rapport à cet élément (144). Dans une première position (Fig. 12), il peut tourner par rapport audit élément (144) et, dans une deuxième position (Fig. 13), il est bloqué en rotation par rapport à cet élément (144). L'invention concerne en outre un procédé pour reconstituer un liquide d'injection et un procédé pour effectuer une injection.
