Tracheostomy Tubes
摘要:
A tracheostomy tube has an inner skeletal frame (40) of a relatively stiff plasties material comprising a longitudinal spine (45) and several annular ribs (42) extending round the frame. A thin, flexible plastics sheath (41) is bonded to the outside of the frame (40). The construction enables a maximum internal diameter with a minimum external diameter.
