Abstract

Un dispositif (10) d'administration d'un liquide, particulièrement utile pour administrer des médicaments sous forme liquide, comprend une chambre (18) de commande par pression qui comporte une cellule électrolytique (22) et un réservoir (17) pour le liquide, séparé de la chambre (18) par une membrane mobile (15). Lorsqu'une pression suffisante se produit dans la chambre (18) et dans le réservoir (19), une seconde membrane (16) se lève pour permettre au liquide de s'échapper du dispositif, par l'intermédiaire d'une ouverture (26) et d'un tube de sortie (20). Le dispositif (10) comporte également une chambre de compensation (19) qui ajuste le débit du liquide en fonction des variations de la température et de la pression ambiantes. On a prévu un capteur de pression (21) sous la forme d'une chambre de détection (27) permettant de détecter d'une manière immédiate une interruption de l'écoulement de liquide hors du dispositif, par l'augmentation de la pression dans le tube de sortie (20), par comparaison avec la pression dans la chambre de compensation (19) et donc le réservoir (17). Le moyen (21) de détection de l'interruption de l'écoulement du liquide n'utilise pas l'augmentation de la pression qui se produit par suite de la production continue de gaz.
