The invention concerns a self-contained perfusion device comprising means for fixing an infusion bag under pressure between a fixed plate and a mobile plate driven by an elastic mechanism, the lower plate (8) is fixed in the vertical direction, while the upper plate (14) is mobile in the vertical direction under the action of the elastic mechanism (15). At least one opening (7) is provided in at least a side wall (5) of the device for inserting an infusion bag (9) between the two plates (8, 14). The elastic mechanism (15) is provided with independent means for controlling and locking the plates (8, 14), and means (24, 25) are provided for unlocking the elastic mechanism (15) after the infusion bag (9) has been loaded. The lower plate (8) can be horizontally mobile like a slide. Means are further provided for controlling the emptying of the bag during perfusion.

Dans un dispositif autonome de perfusion, qui comporte des moyens pour mettre une poche de perfusion sous pression entre une plaque fixe et une plaque mobile entraînée par un mécanisme élastique, la plaque inférieure (8) est fixe en direction verticale, tandis que la plaque supérieure (14) est mobile en direction verticale sous l'action du mécanisme élastique (15). Il est prévu au moins une ouverture (7) dans au moins une paroi latérale (5) du dispositif pour l'introduction d'une poche de perfusion (9) entre les deux plaques (8, 14). Le mécanisme élastique (15) est pourvu de moyens de commande et de verrouillage indépendants des plaques (8, 14), et il est prévu des moyens (24, 25) pour déverrouiller le mécanisme élastique (15) après le chargement de la poche de perfusion (9). La plaque inférieure (8) peut être mobile horizontalement à la manière d'un tiroir. Il est en outre prévu des moyens pour surveiller la vidange de la poche en cours de perfusion.
