Abstract
Abstract An intubating airway having an elongated body comprising a lingual flat portion with a transversely disposed faceplate on one end. The other end comprises a curved surface which tapers to a narrow distal edge. A pair of flexible guide walls are upstanding from said flat lingual portion, to define a generally tubular guideway. Outwardly of the flexible walls are a pair of upstanding walls which attach to said faceplate, to provide a blocking arrangement for a patient's teeth, insuring protection for any medical instrument disposed within said flexible guide.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
An intubating airway adapted for insertion into the mouth of a patient, said airway comprising: an elongated body having opposed first and second ends and a longitudinal axis extending therebetween; a generally flat section adjacent to said first end; faceplate means, transversely disposed across said first end of said body, for abutting against the lips, teeth or gums whereby to prevent said second end from advancing too far into the mouth; curved, generally tongue-shaped portion means adjacent said second end, said curved portion means for permitting placement of said airway between the patient's maxillary and mandibular molars; and flexible guide means for allowing insertion of a medical instrument in or removal of the instrument from said airway in a first, flexed, biased position but normally being in a second, relaxed, unbiased position, said guide means comprising at least one pair of opposed walls upstanding from only said flat section and extending longitudinally down said flat section, said walls being spaced apart and each said wall having an uppermost distal edge which is curved towards the opposed said wall, said distal edges being spaced apart whereby said edges may be flexed further apart to facilitate said insertion or said removal of the medical instrument within said airway.
Claim 2
Dependent Claim
206 words
An intubating airway adapted for insertion into the mouth of a patient, said airway comprising: an elongated body having opposed first and second ends and a longitudinal axis extending therebetween; a generally flat section adjacent to said first end; faceplate means, transversely disposed across said first end of said body, for abutting against the lips, teeth or gums whereby to prevent said second end from advancing too far into the mouth; curved, generally tongue-shaped portion means adjacent said second end, said curved portion means for permitting placement of said airway between the patient's maxillary and mandibular molars; and flexible guide means for allowing insertion of a medical instrument in or removal of the instrument from said airway in a first, flexed, biased position but normally being in a second, relaxed, unbiased position, said guide means comprising at least one pair of opposed walls upstanding from only said flat section and extending longitudinally down said flat section, said walls being spaced apart and each said wall having an uppermost distal edge which is curved towards the opposed said wall, said distal edges being spaced apart whereby said edges may be flexed further apart to facilitate said insertion or said removal of the medical instrument within said airway.
Claim 3
Dependent Claim
30 words
An airway as defined in claim 1 wherein said second end is a generally flat end open for permitting manipulation of the tip of a medical instrument when inserted thereon.
Claim 4
Dependent Claim
36 words
An airway as defined in claim 1 wherein said guide means further includes a second pair of said upstanding walls also extending along said flat section adjacent said first end and being attached to said faceplate.
Claim 5
Dependent Claim
166 words
An intubating airway for insertion into the mouth of a patient, said airway comprising: an elongated body having generally flat first and second ends and a longitudinal axis extending therebetween; curved, generally tongue-shaped portion means adjacent said second end, said curved portion means for permitting placement of said airway between the patient's maxillary and mandibular molars; and flexible guide means for allowing insertion of a medical instrument in or removal of the instrument from said airway in a first, flexed, biased position but normally being in a second, relaxed, unbiased position, said guide means comprising at least one pair of opposed walls upstanding from only said first flat end and extending longitudinally down said first flat end, said walls being spaced apart and each said wall having an uppermost distal edge which is curved towards the opposed said wall, said distal edges being spaced apart whereby said edges may be flexed further apart to facilitate said insertion or said removal of the medical instrument within airway.
Claim 6
Dependent Claim
166 words
An intubating airway for insertion into the mouth of a patient, said airway comprising: an elongated body having generally flat first and second ends and a longitudinal axis extending therebetween; curved, generally tongue-shaped portion means adjacent said second end, said curved portion means for permitting placement of said airway between the patient's maxillary and mandibular molars; and flexible guide means for allowing insertion of a medical instrument in or removal of the instrument from said airway in a first, flexed, biased position but normally being in a second, relaxed, unbiased position, said guide means comprising at least one pair of opposed walls upstanding from only said first flat end and extending longitudinally down said first flat end, said walls being spaced apart and each said wall having an uppermost distal edge which is curved towards the opposed said wall, said distal edges being spaced apart whereby said edges may be flexed further apart to facilitate said insertion or said removal of the medical instrument within airway.
