Abstract
A pharyngeal bulb airway adapted to be placed in the airway of a person who is otherwise incapable of self sustained breathing, consists of a pliable, hollow dome-like-shaped bulb connected to a breathing tube. Insertion of the pharyngeal bulb airway breathing device into the airway of a person is facilitated by compressing the bulb to reduce its size, and by the use of a flexible rod or wire to maintain the reduced size until the breathing device is properly positioned. The flexible rod or wire is threaded through holes formed within the dome-like-shaped bulb after the bulb has been collapsed. When the wire is removed from the holes, the bulb resumes its normal dome-like shape. The bulb is preferably adapted to be placed in the pharynx with the holes facing in the direction of the epiglottis.
Claims15
A pharyngeal bulb airway adapted to be positioned in the airway of a patient, the device comprising:
- a breathing tube adapted to extend out through the mouth of a patient;
- a hollow bulb adapted to be inserted within the throat of the patient being connected to the breathing tube, the hollow bulb being constructed of a pliant material capable of allowing the hollow bulb to be either expanded in a normal shape or compressed into a collapsed condition;
- and
- a flexible rod or wire extending along the breathing tube and into the bulb and being releasably attached to the bulb to either selectively retain the bulb in the collapsed condition or to allow the bulb to resume its normal shape.
A pharyngeal bulb airway adapted for insertion into the airway of an unconscious person and comprising, in combination,
- a) a breathing tube having a first end adapted to be vented to the atmosphere or connected to suitable life-sustaining apparatus and a second end;
- b) a hollow, flexible, generally oval bulb connected to the second end of the tube in open communication therewith, the bulb having a generally planar surface and a domelike-shaped surface opposite the planar surface, the dome-like-shaped surface containing a plurality of discrete openings, the dome-like-shaped surface adapted to be manipulated toward the planar surface to collapse the bulb for ease of insertion of the device into the airway, and
- c) a flexible rod or wire extending the length of the breathing tube from the first end to the second end and into the bulb, the flexible rod extending out of the bulb through one of the openings in the dome-like shaped surface and back into the bulb through a second of the openings whereby the bulb is maintained in a generally collapsed condition during insertion of the device into the airway.
