The present invention relates to a double connector 24 for a tubular insert 22 intended to connect an extra-corporeal circuit 20 to a peristaltic pump 18. The double connector comprises: a first channel 30 with an axis a 1 , a second channel 32 with an axis a 2 not parallel to a 1 , a pressure chamber 34 arranged along the first channel 30 and suitable for co-operation with a pressure sensor 16. The pressure chamber is closed, on the opposite side with respect to the second channel 32, by a membrane 36 which extends mainly in a plane À substantially parallel to both the axes a 1 and a 2 . Moreover, a straight line r, passing through both axes a 1 and a 2 and perpendicular thereto, crosses the membrane. The invention also relates to a tubular insert 22 comprising the double connector 24 and an extra-corporeal circuit 20 comprising the tubular insert. |
