Coupling arrangement

Abstract

The present invention relates to a coupling arrangement for a system for endotracheal ventilation of a patient, which system comprises an endotracheal tube and a manifold ( 100 ) configured for allowing ventilation of the patient via said endotracheal tube, which manifold ( 100 ) has a first coupling means ( 300 ) with an axial extent ( 400 ) and with engagement means ( 330 ); and which endotracheal tube has a second coupling means ( 400 ) with an axial extent and with engagement means ( 420 ); wherein the coupling arrangement is configured to produce, when the first ( 300 ) and the second ( 400 ) coupling means are moved together in the axial 360 direction, a locking engagement between the engagement means ( 33, 420 ). The invention is characterised in that the first coupling means ( 300 ), in the axial direction, comprises an exterior screw thread ( 320 ); and that the second coupling means ( 400 ) comprises an exterior abutment face ( 430 ); that the coupling arrangement also comprises a disengagement means ( 350 ) configured for cooperating with said screw thread ( 320 ); and that the disengagement means ( 350 ) and the screw thread ( 320 ) are configured for allowing an axial movement of the disengagement means ( 350 ) from a first position, in which said engagement means ( 330, 420 ) are in locking engagement, to a second position in which the disengagement means ( 350 ) can influence the abutment face ( 430 ) by an axial force for releasing the locking engagement.
