CA 2305055

Obturator for tracheostomy tubes are known having a nose at the patient end protruding from the tube and having a machine end with clips that fasten to a coupling on the tube. In the present invention, the obturator has a strap extending between the nose and machine end formed by one web extending along its entire length and a second web extending orthogonally on one side of the first web to form a T shape section along the major part of the strap towards its patient end. This makes the patient end of the strap relatively rigid whilst its machine end is relatively flexible to enable the machine end to be twisted to release the engagement of the clips and to enable the obturator to be pulled out of the tube.
