Some four or five years ago, while his own physician was away, a man who had always worn a tracheotomy tube came to me to have the same replaced. The tube had been out some days and the opening was contracted from side to side. On trying to replace it, the tube acted much like a reamer or corer, and would not slip in without paring the edges of the opening. Resort to the makeshift shown in the illustration made the introduction easy. The matter passed entirely from mind until recently my brother, Dr. W. H. Tuckerman, had a like difficulty in introducing a tube, larger than the one being worn, into the trachea of a growing child who has constantly to wear a tube. Again the device shown made the procedure easy.
An obturator might very well be a part of every tracheotomy tube. A tip could be made with a shoulder
