Oropharyngeal airway
First Claim
1. An oropharyngeal device positionable within an airway of a patient, the oropharyngeal device comprising:
- a generally hollow body having an upper half and a lower half located diametrically opposite the upper half and a proximal end positionable adjacent the patient'"'"'s mouth and an opposite distal edge positionable adjacent and spaced from the patient'"'"'s epiglottis when the proximal end is positioned adjacent the mouth;
a supply passage for delivering oxygen to the patient, the supply passage having a discharge port fluidly connecting the supply passage to an exterior region of the oropharyngeal device, wherein the discharge port is located only along the upper half of the body between the distal edge and the proximal end; and
a sensing passage for sampling a patient'"'"'s expiration, the sensing passage including an inlet port located only along the lower half of the body at the distal edge.

Abstract
An oropharyngeal device positionable within an airway of a patient may include a hollow body having a proximal end positionable adjacent the patient'"'"'s mouth and an opposite distal end positionable adjacent and spaced from the patient'"'"'s epiglottis. The body includes a center channel extending from the proximal end to the distal end of the body. The oropharyngeal device may include a supply passage for delivering oxygen to the patient. The supply passage may include at least one of a discharge port fluidly connecting the supply passage to an exterior region of the oropharyngeal device and a discharge port fluidly connecting the supply passage to the center channel. The discharge ports may be positioned along a wall of the body between the distal and proximal ends. The oropharyngeal device may include a sensing passage for sampling a patient'"'"'s respiratory composition positioned adjacent the distal end of the body.

10. An oropharyngeal device positionable within an airway of a patient, the oropharyngeal device comprising:
-
a generally hollow body having an upper half and a lower half located diametrically opposite the upper half and a proximal end positionable adjacent the patient'"'"'s oropharyngeal inlet and an opposite distal edge positionable adjacent and superior to the patient'"'"'s epiglottis when the proximal end is positioned adjacent the mouth, the body being curved along its longitudinal axis to form an inside curved region and an outside curved region located diametrically opposite the inside curved region; a supply passage for delivering oxygen to the patient, the supply passage having a discharge port fluidly connecting the supply passage to an exterior region of the oropharyngeal device, wherein the discharge port is only located within the upper half of the body along the outside curved region between the distal edge and the proximal end; and a sensing passage for sampling a patient'"'"'s respiratory composition, the sensing passage including an inlet port located only along the lower half of the body at the distal edge. - View Dependent Claims (11, 12, 13)
