An introducer for a tracheostomy tube is formed of several articulated sections (24) that can be changed from a relatively flexible state to a more rigid state by tightening a tension member extending along the introducer using an actuator at its machine end. In its flexible state the introducer can be inserted into and removed from the tube. The introducer is put in its more rigid state for use in inserting the tube into a tracheostomy. Alternatively or additionally the introducer could have several gripping rings on its outside towards its patient end and two elongate members that can be slid relative to one another to enlarge the patient end so that the gripping rings engage and grip the inside of the tube, thereby enabling the introducer to pull the tube through the tracheostomy from its patient end.

A tube introducer adapted for insertion within the bore of a medico-surgical tube, characterised in that the introducer is selectively configurable from a first state where it is removable from the machine end of the tube to a second state where it supports the tube during insertion into the body.
A tube introducer adapted for insertion within the bore of a medico-surgical tube from the machine end of the tube, characterised in that the introducer has at least a region along its length towards its patient end with an external dimension that can be selectively changed from a first dimension where it enables the introducer to be slid into and out of the tube to a second, larger dimension where the outside of a part at least of the region can grip the inside of the tube to resist relative movement between the introducer and the tube.
A tube introducer having a patient end adapted for insertion in the bore of a medico-surgical tube to extend substantially to the patient end of the tube and a machine end adapted to project externally beyond the machine end of the tube, characterised in that the introducer is arranged selectively to grip the inside of the tube close to the patient end of the tube such that the tube and introducer can be inserted into a body cavity by pushing the machine end of the introducer so as to pull the tube into the body cavity from its patient end.
An assembly of a medico-surgical tube and a tube introducer adapted to be selectively configurable from a first state where it is removable from the machine end of the tube to a second state where it supports the tube during insertion into a body, wherein the introducer is inserted within the tube with the patient end of the introducer protruding at the patient end of the tube and the machine end of the introducer accessible at the machine end of the tube.
