The invention relates to a device for delivering fluids, especially pressurised medicating fluids. Said device comprises a recipient (1) with a variable volume in the form of a pocket or a generally cylindrical bag with longitudinal folds (2), containing the pressurised fluid to be delivered and provided with a control C for opening a valve (15a, 15b) for delivering the liquid. The arrangement is provided inside a container (4) which is resistant to a high internal pressure, the volume inside said container between the wall and the recipient with a variable volume being filled with a neutral gas under a sufficient pressure to be able to exert on the recipient with a variable volume a pneumatic stress which is sufficient to enable the fluid contained in the recipient to be delivered when the valve enabling the delivery is actuated by the control C.
L'invention a pour objet un dispositif du genre de ceux qui sont aptes à délivrer des fluides, notamment médicamenteux, sous pression. Ce dispositif comporte un récipient (1) de volume variable en forme de poche ou de sac de forme générale cylindrique à plis longitudinaux (2) contenant le fluide sous pression à délivrer et muni d'une commande C permettant d'ouvrir un clapet (15a, 15b) pour délivrer ledit liquide, l'ensemble étant disposé à l'intérieur d'un récipient (4) résistant à une pression intérieure élevée, le volume intéreur de ce dernier récipient compris entre sa paroi et le récipient à volume variable étant rempli d'un gaz neutre sous une pression suffisante pour exercer sur le récipient à volume variable une contrainte pneumatique suffisante pour permettre de délivrer le fluide que contient ce dernier lorsque le susdit clapet permettant cette délivrance est actionné par la susdite commande C.
