The inventive pressure transmitting connector, in particular for an endoscopy system comprises a fluid transporting channel (19, 21), a blind compartment (39a, 39b) which open (41a, 41b) towards the transport channels (19, 21) by a pipe (41a, 41b) and closed by a membrane (37a, 37b) which is deformable according to a pressure in said transport channels (19, 21) and means for transmitting a representative quantity of the pressure in the transport channel according to the membrane deformation. According to said invention, the transport channel (19, 21), the pipe (41a, 41b) and the blind compartment (39a, 39b) are embodied in the same rigid part (43) to which the membrane (37a, 37b) is attached. In a preferred embodiment, the membrane (37a, 37b) simultaneously closes the blind compartment (39a, 39b) and a pressure transmitting chamber (35a, 35b) attached to said rigid part (43).

Connecteur à détection de pression destiné plus particulièrement à un système d'endoscopie, comprenant une voie de communication à fluide (19, 21), un compartiment borgne (39a, 39b) ouvert (41a, 41b) sur la voie de communication (19, 21) par un conduit (41a, 41b) et fermé par une membrane (37a, 37b) se déformant en fonction d'une pression dans la voie de communication (19,21) et un moyen pour transmettre une grandeur représentative de la pression dans la voie de communication en fonction de la déformation de la membrane. Selon l'invention, la voie de communication (19, 21), le conduit (41a, 41b) et le compartiment borgne (39a, 39b) sont formés dans une même pièce rigide (43) sur laquelle la membrane (37a, 37b) est rapportée. De préférence, la membrane (37a, 37b) ferme à la fois le compartiment borgne (39a, 39b) et une chambre à transmission de pression (35a, 35b) rapportée sur la pièce rigide (43).
