Abstract

The present invention concerns a respiratory suction system for providing ventilation of a patient's respiratory tract, the system comprising an elongated catheter with a distal end, a manifold defining a flow path in a ventilator circuit and comprising access structure allowing the catheter to be advanced through the manifold and into a respiratory tract of a patient, the access structure including a valve which is openable in response to the advancement of the catheter through the valve and into the flow path. The valve has a proximal end has an annular outer flange section, a distal end and a tubular body extending between the proximal end and the distal end, the tubular body having a plurality of valve members extending from the annular flange section to the distal end which has end surfaces wherein a plurality of radial slits are provided, extending from the center towards the periphery and thereby separating the valve members at the distal end.
