1. A connector intended for an endoscopy system, said connector comprising: a communication channel for fluid communication with a coupling channel of a coupling ring of an endoscopy system,a blind channel for fluid communication with a branch-off channel of the coupling ring of the endoscopy system
1. A connector intended for an endoscopy system, said connector comprising: a communication channel for fluid communication with a coupling channel of a coupling ring of an endoscopy system,a blind channel for fluid communication with a branch-off channel of the coupling ring of the endoscopy system,a first pressure sensor facing the communication channel for sensing the pressure in the communication channel, anda second pressure sensor facing the blind channel for sensing the pressure in the blind channel,whereinthe communication channel is an irrigation communication channel and the connector includes a second communication channel which is an outflow communication channel,the connector comprises a rigid body provided with the irrigation and outflow communications channels and with the blind channel,the first sensor comprises a first deformation chamber and a first membrane and the second sensor comprises a second deformation chamber and a second membrane, each of the first and second membranes being designed to be deformed and to cause pressure in the first and second chamber, respectively, to vary,the rigid body comprises a first transmission chamber in fluid communication with the irrigation and outflow communication channels and a second transmission chamber in fluid communication with the blind channel, andthe first transmission chamber is closed off by the first membrane and the second transmission chamber is closed off by the second membrane. 2. The connector as claimed in claim 1, wherein the branch-off channel is in fluid communication with the two communication channels. 3. The connector as claimed in claim 2, wherein the pressure sensors are membrane sensors. 4. The connector as claimed in claim 1, wherein the pressure sensors are membrane sensors. 5. The connector as claimed in claim 1, wherein the pressure sensors are membrane sensors. 6. The connector as claimed in claim 1, wherein the irrigation and outflow communication channels and the blind channel are located between the first and second sensors. 7. The connector as claimed in claim 1, wherein the irrigation and outflow communication channels and the blind path channel are arranged substantially along a same plane, and the first and second sensors are arranged on opposite sides of the plane. 8. The connector as claimed in claim 1, wherein the connector comprises a polarizing feature and the coupling ring comprises a corresponding polarizing feature, so that a connection of the connector on the coupling ring is polarized. 9. The connector as claimed in claim 1, wherein a first end of the communication channel and an end of the blind channel open on a coupling face of the connector, and a second end opposite the first end of the communication channel is connected to a pump via tubings for creating a flow into the communication channel. 10. The connector as claimed in claim 1, wherein first ends of the irrigation and outflow communication channels and an end of the blind channel open on a coupling face of the connector, and second ends opposite the first ends of the irrigation and outflow communication channel are connected to a pump via tubings for creating a flow into the communication channel and out of the outflow channel.
