A pressure control device for maintaining the pressure level of a cuff (100b) of a medical device, wherein the pressure control device comprises an air reservoir (2) filled with air at a pressure between a first predetermined pressure and a second predetermined pressure that is higher than the first predetermined pressure a first valve (6), which is connected to the air reservoir (2) at one end and to an inflating tube (100c) for the cuff (100b) at the other end so as to form a first air flowing path (A), wherein when the cuff (100b) pressure is below the first predetermined pressure, the first valve (6) allows air in the air reservoir (2) to flow to the cuff (100b) through the first air flowing path (A) so as to increase the cuff (100b) pressure to a level above the first predetermined pressure and a second valve (7), which is connected to the air reservoir (2) at one end and to the inflating tube (100c) for the cuff (100b) at the other end so as to form a second and parallel air flowing path (B), wherein when the cuff (100b) pressure is above the second predetermined pressure, the second valve (7) allows air in the cuff (100b) to flow to the air reservoir (2) through the second air flowing path (B) so as to decrease the cuff (100b) pressure to a level below the second predetermined pressure. A cuffed endotracheal tube with the pressure control device, and a cuffed laryngeal mask (100) with the pressure control device.Un dispositif de contrôle de pression pour maintenir le niveau de pression du brassard (100b) du dispositif médical, dans lequel le dispositif de contrôle de pression comprend un réservoir dair (2) remplie dair dont la pression est comprise entre une première pression prédéterminée, et une seconde pression prédéterminée, qui est supérieure à la première pression prédéterminée une première soupape (6), qui est reliée au réservoir dair (2), à une extrémité, et à un tube de gonflage (100c) pour le brassard (100b), à lautre extrémité, de façon à former un
