Abstract

An emergency resuscitation apparatus is provided by an endotracheal tube having a tracheal obturator and a second expandable cuff for sealing against the pharyngeal tissues to provide an alternate sealing means for respiratory fluids if the blind intubation is not successful. A laryngeal tube passes through this pharyngeal obturator for alternatively introducing respiratory fluids into the lungs through the larynx. The endotracheal tube may also be used as an esophageal obturator and inserted without the intubating guide means. The endotracheal and laryngeal tubes may be individually accessed from outside the patient. An inflation system is provided to expand the cuffs. When low pressure cuffs are used, a mouthpiece is provided for inflating the cuffs by breathing. A face shield supports the extending tubes and insures intubation to a correct depth.

Claims

1. An emergency endotracheal airway, comprising:

a first expandable member and means for inflating said first expandible member by at least human breath to a volume effectively filling a pharyngeal region adapted to continuously seal both the oral and nasal passages extending therefrom;

an endotracheal tube extending through said first expandable member and having an outer opening above said first expandable member and an inner opening below said first expandable member adapted to terminate in a trachea,

a second expandable member and means for inflating said second expandible member by at least human breath surrounding said endotracheal tube adjacent said inner opening and adapted to continuously seal against a wall portion of said trachea,

a laryngeal tube extending through said first expandable member and having an outer opening adapted to receive a supply of a selected fluid and an inner opening below said first expandable member adapted to terminate in a laryngeal region above said second expandable member; and

a stylet removably inserted through said endotracheal tube and having a predetermined curvature and one rounded end adapted to guide said inner opening of said endotracheal tube into the trachea during insertion thereof,

whereby when said endotracheal tube is properly inserted into said trachea, a patient can be ventilated by inflating said second expandible member and, if desired, said first expandable member, and administering gas to the patient'"'"'s lungs via said endotracheal tube, and if said endotracheal tube is accidentially inserted into the patient'"'"'s esophagus, the patient can be ventilated by inflating said first and second inflatable members and administering gas to the patient'"'"'s lungs via said laryngeal tube.

2. An emergency endotracheal airway as described in claim 1, wherein said endotracheal tube further includes

indicator meand cooperating with said outer opening of said endotracheal tube to signal the presence of fluid within said endotracheal tube.

3. An emergency endotracheal airway as described in either in claim 1 or 2, further including:

a shield surrounding said endotracheal tube and said laryngeal tube adapted to position said tubes within a patient and protect said tubes from penetration by teeth.

4. An emergency endotracheal airway as described in claim 3, further including:

valve means communicating with said first and second expandable members for maintaining inflation pressures, and

means for indicating the presence of greater than atmospheric pressure in said first and second expandable members.
