Abstract
Abstract There is disclosed an oropharyngeal airway (10) which comprises a curved portion (11) which provides a pharyngeal end (12) of the airway, and a straight portion (13) which communicates with the curved portion (11) and which provides a buccal end (14) of the airway. The straight portion (13) is formed integrally with the curved portion (11) and is made from plastics and/or elastomeric material. At least one circular cross- section passage extends substantially throughout the length of the straight portion (13), and the straight portion (13) has a substantial wall thickness surrounding the passage to provide rigidity sufficient to resist collapse of the straight portion under biting-action of a patient. Conveniently, one of the passages serves as a catheter guide, while the remaining passage serves to convey air to the curved portion. <IMAGE>

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
68 words
An oropharyngeal airway comprising a curved portion which provides a pharyngeal end of the airway, and a straight portion which communicates with the curved portion and which provides a buccal end of the airway;
in which the straight portion is formed of plastics and/or elastomeric material and has at least one through-passage formed therein with a surrounding wall thickness sufficiednt to prevent collapse under biting-action of a patient.
Claim 2
Dependent Claim
68 words
An oropharyngeal airway comprising a curved portion which provides a pharyngeal end of the airway, and a straight portion which communicates with the curved portion and which provides a buccal end of the airway;
in which the straight portion is formed of plastics and/or elastomeric material and has at least one through-passage formed therein with a surrounding wall thickness sufficiednt to prevent collapse under biting-action of a patient.
Claim 3
Dependent Claim
45 words
An airway according to claim 1, in which two passages are provided in the straight portion, at least one of which can be used to guide the insertion of a catheter while the other serves to convey air to the curved portion of the airway.
Claim 4
Dependent Claim
34 words
An airway according to claim 1 or 2, in which the cross-sectional area of the passage, or the combined cross-sectional areas of the passages, is greater than the internal cross-section of the curved portion.
Claim 5
Dependent Claim
21 words
An airway according to any one of the preceding claims, in which the or each passage is circular in cross section.
Claim 6
Dependent Claim
21 words
An airway according to any one of the preceding claims, in which the airway is made of plastics and/or elastomeric material.
Claim 7
Dependent Claim
14 words
An airway according to claim 5, in which the airway is made of E.V.A.
Claim 8
Dependent Claim
100 words
An oropharyngeal airway comprising a curved portion which provides a pharyngeal end of the airway, and a straight portion which communicates with the curved portion and which provides a buccal end of the airway;
in which the straight portion is formed integrally with the curved portion and is made from plastics and/or elastomeric material with at least one circular cross-section passage extending substantially throughout the length of the straight portion, said straight portion having a substantial wall thickness surrounding the passage to provide rigidity to the straight portion for resisting collapse of the straight portion under biting-action of a patient.
Claim 9
Dependent Claim
100 words
An oropharyngeal airway comprising a curved portion which provides a pharyngeal end of the airway, and a straight portion which communicates with the curved portion and which provides a buccal end of the airway;
in which the straight portion is formed integrally with the curved portion and is made from plastics and/or elastomeric material with at least one circular cross-section passage extending substantially throughout the length of the straight portion, said straight portion having a substantial wall thickness surrounding the passage to provide rigidity to the straight portion for resisting collapse of the straight portion under biting-action of a patient.
Claim 10
Dependent Claim
38 words
An airway according to claim 7, including a first passage formed in the straight portion to guide the insertion of a catheter and a second passage formed in the straight portion to convey air to the curved portion.
Claim 11
Dependent Claim
35 words
An airway according to claim 7 or 8, in which the cross-sectional area of the passage, or the combined cross-sectional area of the passages, is greater than the internal cross-sectional area of the curved portion.
Claim 12
Dependent Claim
21 words
An airway according to claim 1 and substantially as hereinbefore described with reference to, and as shown in the accompanying drawings.
