A tracheostomy tube introducer 2 has a straight handle 20 of a rigid plastics material moulded onto a curved midsection 21. The midsection comprises an outer shaft 29 of a polyurethane and an inner rigid metal tube 28. The outer shaft 29 continues forwardly beyond the end of the metal tube 28 to provide a flexible, tapering patient end tip 22. When inserted in a tracheostomy tube 1, the handle 20 protrudes from the machine end 13, the midsection 21 retains the tube in the desired curvature for insertion in the patient, and the patient end provides a flexible tip 22 that protrudes by about three times the external diameter of the tube. <IMAGE> |
