This head-piece may also be used for m-tra-tracheal insufflation. The tube leading to the head-piece in this case has aY-tube inserted in its course near the brass cylinder of the head-piece. Fromthe two forks of the Y-tube short rubber tubes carrying screw clamps pass tothe cylinder. One of these ttibes connects onto the inlet tube as usual. The General Analgesia and Anccsthcsia 7 other rubber tube is connected with the inside of the cyHnder by means of asmall metal or glass tube passing through a cork inserted in an opening in thebrass cylinder (not shown in the diagram).
