Abstract: A conventional ventilating apparatus is connected to the projecting end of a breathing tube inserted through a tracheostomy opening into the patient's throat with an inflatable cuff at the lower end of the tube to seal the patient's throat. An adapter is provided to connect the ventilating apparatus to the tracheal tube. A port is defined in the adapter, opposite the portion of the adapter for connection to the tube, such that removal of a plastic cap permits insertion of a vacuum tube for withdrawing excessive fluid from the patient's lungs. The ventilating apparatus connects with the adapter through a side opening port and this disclosure relates particularly to still another port provided for connecting the tracheal tube to a source of lubricating fluid for purposes of injecting a saline solution or other lubricant into the patient's lungs when required to relieve dryness in the patient's lungs.
