Patent ID: 7721738

Claim:
A system for endotracheal ventilation of a patient, said system comprising: an endotracheal tube and a manifold configured for allowing ventilation of the patient via said endotracheal tube; a first coupling means on said manifold having an axial extent, said first coupling means defining a first engagement means and comprising an exterior screw thread; a second coupling means on said endotracheal tube having an axial extent, said second coupling means defining a second engagement means and comprising an exterior abutment face; and a disengagement means mounted to said first coupling means defining an internal thread configured for cooperating with said exterior screw thread; wherein said system is configured to produce a locking engagement between said first and second engagement means, when said first coupling means and said second coupling means are moved together in the axial direction, and wherein said disengagement means and said exterior screw thread are configured for allowing, by rotation of the disengagement means, an axial movement of the disengagement means from a first position, wherein said first and second engagement means are in locking engagement and said disengagement means is spaced apart from said exterior abutment face, to a second position wherein said disengagement means contacts said exterior abutment face and applies an axial force on said exterior abutment face sufficient for releasing the locking engagement by forcing said first and second coupling means apart from each other, and said first coupling means together with said disengagement means are removably released from said second coupling means, said disengagement means and said second coupling means being configured so that there is no contact between said disengagement means and said second coupling means when said disengagement means is in said first position.
