An arrangement comprising an instillation catheter (6) and a connector piece (1) for attachment to a tracheal or endotracheal tube is proposed. Said arrangement provides an access route which can be leakproof and at the same time permits mobility and exact positioning of the instillation catheter (6). The connector piece (1) has a distal end (1a) for attachment to the tube, and a proximal end (1b) for attachment to a ventilation and/or suction device and comprises a branch (5) which serves for insertion of the catheter (6) and in which a valve (2) is arranged. The valve (2) is made, at least in some areas, from the elastic deformable material and can be opened by insertion of the catheter (6). The valve further comprises a proximal through opening (21) whose inner wall has a means allowing sealing against axial flow of fluid between the catheter (6) and the inner wall, and in the distal direction from the through opening there is a beak section (22) which has a normally closed slit (24) at its beak tip (23). |
