Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 166 words
In a gas delivery apparatus including a gas flow conducting means and adapted for delivery of medical gas to a patient from an external gas source through the patient's mouth via the gas flow conducting means which extends into the patient's mouth and further including seal means adapted to seal the patient's mouth and nasal openings from the ambient atmosphere, the improvement comprising: said seal means comprising deformable means encompassing said gas flow conducting means and including a formable exterior wall disposed for confronting relationship with the patient's face throughout an area of contact having an outer perimeter which encompasses the patient's mouth and nasal openings such that said area of contact extends continuously intermediate said gas flow conducting means and said outer perimeter, said formable exterior wall being adapted to conform to the patient's facial contours throughout said area of contact to provide a continuous surface seal throughout said area of contact for sealing of the patient's mouth and nasal openings from the ambient atmosphere.
Claim 2
Dependent Claim 166 words
In a gas delivery apparatus including a gas flow conducting means and adapted for delivery of medical gas to a patient from an external gas source through the patient's mouth via the gas flow conducting means which extends into the patient's mouth and further including seal means adapted to seal the patient's mouth and nasal openings from the ambient atmosphere, the improvement comprising: said seal means comprising deformable means encompassing said gas flow conducting means and including a formable exterior wall disposed for confronting relationship with the patient's face throughout an area of contact having an outer perimeter which encompasses the patient's mouth and nasal openings such that said area of contact extends continuously intermediate said gas flow conducting means and said outer perimeter, said formable exterior wall being adapted to conform to the patient's facial contours throughout said area of contact to provide a continuous surface seal throughout said area of contact for sealing of the patient's mouth and nasal openings from the ambient atmosphere.
Claim 3
Dependent Claim 29 words
The improvement as claimed in claim 1 wherein said deformable means includes a fluid contained within a bladder and said exterior wall is an exterior wall of said bladder.
Claim 4
Dependent Claim 12 words
The improvement as claimed in claim 2 wherein said fluid is water.
Claim 5
Dependent Claim 13 words
The improvement as claimed in claim 2 wherein said fluid is a gas.
Claim 6
Dependent Claim 29 words
The improvement as claimed in claim 2 wherein the volume of fluid contained within said bladder is less than the volume of fluid required to distend said exterior wall.
Claim 7
Dependent Claim 29 words
The improvement as claimed in claim 2 wherein said deformable means includes a mass of closed cell foam and said exterior wall is an exterior wall of said mass.
Claim 8
Dependent Claim 245 words
A medical gas administering apparatus adapted for administering gas to a patient comprising: an elongated body; said elongated body including an elongated formed beam which is adapted to be received within the mouth and throat of such a patient with an outer end portion of said beam extending outwardly of the patient's mouth; said beam being formed to define at least one laterally open gas flow passage extending longitudinally thereof for permitting gas flow within the mouth and throat and to the airway of such a patient; said body including gas flow conducting means located adjacent said outer end portion of said beam; said gas flow conducting means defining a gas flow passage which communicates with said at least one laterally open passage adjacent said outer end portion of said beam for delivery of gas to such a patient; seal means comprising a deformable means which encompasses said elongated body intermediate the longitudinal ends thereof and includes a formable exterior wall disposed for confronting relationship with the patient's face throughout an area of contact having an outer perimeter which encompasses the patient's mouth and nasal openings such that said area of contact extends continuously intermediate said elongated body and said outer perimeter whereby said formable exterior wall is adapted to conform to the patient's facial contours throughout said area of contact to provide a continuous surface seal throughout said area of contact for sealing of the patient's mouth and nasal openings from the ambient atmosphere.
Claim 9
Dependent Claim 245 words
A medical gas administering apparatus adapted for administering gas to a patient comprising: an elongated body; said elongated body including an elongated formed beam which is adapted to be received within the mouth and throat of such a patient with an outer end portion of said beam extending outwardly of the patient's mouth; said beam being formed to define at least one laterally open gas flow passage extending longitudinally thereof for permitting gas flow within the mouth and throat and to the airway of such a patient; said body including gas flow conducting means located adjacent said outer end portion of said beam; said gas flow conducting means defining a gas flow passage which communicates with said at least one laterally open passage adjacent said outer end portion of said beam for delivery of gas to such a patient; seal means comprising a deformable means which encompasses said elongated body intermediate the longitudinal ends thereof and includes a formable exterior wall disposed for confronting relationship with the patient's face throughout an area of contact having an outer perimeter which encompasses the patient's mouth and nasal openings such that said area of contact extends continuously intermediate said elongated body and said outer perimeter whereby said formable exterior wall is adapted to conform to the patient's facial contours throughout said area of contact to provide a continuous surface seal throughout said area of contact for sealing of the patient's mouth and nasal openings from the ambient atmosphere.
Claim 10
Dependent Claim 20 words
The apparatus as claimed in claim 7 wherein said gas flow conducting means is an elongated open ended tube means.
Claim 11
Dependent Claim 25 words
The apparatus as claimed in claim 8 wherein said outer end portion of said beam is received within one open end of said tube means.
Claim 12
Dependent Claim 19 words
The apparatus as claimed in claim 7 wherein said beam defines a pair of laterally open gas flow passages.
Claim 13
Dependent Claim 22 words
The apparatus as claimed in claim 10 wherein said pair of laterally open gas flow, passages are laterally opposed gas flow passages.
Claim 14
Dependent Claim 18 words
The apparatus as claimed in claim 11 wherein said beam is generally of an I-beam cross sectional configuration.
Claim 15
Dependent Claim 18 words
The apparatus as claimed in claim 11 wherein said beam is generally of a figure-eight cross sectional configuration.
Claim 16
Dependent Claim 33 words
The apparatus as claimed in claim 7 wherein said seal means includes a formable medium having an exterior wall portion adapted to be located for confronting relationship with the face of such patient.
Claim 17
Dependent Claim 30 words
The apparatus as claimed in claim 14 wherein said formable medium is a fluid contained within a bladder and said exterior wall portion is an exterior wall of said bladder.
Claim 18
Dependent Claim 13 words
The apparatus as claimed in claim 15 wherein said fluid is a gas.
Claim 19
Dependent Claim 12 words
The apparatus as claimed in claim 15 wherein said fluid is water.
Claim 20
Dependent Claim 30 words
The apparatus as claimed in claim 14 wherein said formable medium is a mass of closed cell foam and said exterior wall portion is an exterior wall of said mass.
Claim 21
Dependent Claim 27 words
The apparatus as claimed in claim 15 wherein the volume of said fluid within said bladder is less than the volume required to distend said exterior wall.
