Abstract
Abstract An intubation device for inhalation of gases including a cannula connected to an endotracheal tube having a first inflatable member mounted thereon for sealing contact with the base of the tongue, the soft palate and lateral pharyngeal walls together with a fluid supply tube for inflating the first inflatable member. A second inflatable member mounted on the tube for sealing contact with the trachea with a fluid supply tube for inflating the second inflatable member and a device for connecting one of the leads of the cannula to the outer end of the tube. An oro-pharyngeal tube having a single inflatable barrier for sealing contact with the base of the tongue, soft palate and lateral pharyngeal walls together with a fluid supply tube for inflating the inflatable barrier and a device for connecting one of the cannula leads to the other end of the tube.
