Abstract
An oral airway providing a patent airway to a patient, supplies oxygen to the patient and monitors expelled gases during endoscopic or intubating procedures. The oral airway includes a central lumen and two lateral breathing channels. A bracket at the proximal end of the oral airway functions to guide an oxygen supply line and an end tidal carbon dioxide monitoring line into the lateral breathing channels and to act as a barrier beyond which the airway cannot be inserted into the mouth of the patient. The airway has a straight main central lumen which serves as a guide and conduit to facilitate endoscope, bronchoscope, or fiber optic bronchoscope placement and manipulation.
Claims23
An oral airway, the oral airway comprising:
- a central airway lumen having a passageway, the central airway lumen having a proximal end and an opposite distal end;
- a first breathing channel positioned adjacent to the central airway lumen, the first breathing channel having a gas supply line, the gas supply line adapted to supply gas from a gas supply device to the passageway;
- and
- a second breathing channel positioned adjacent to the central airway lumen and opposite the first breathing channel, the second breathing channel having a gas monitoring line for monitoring gases expelled from a patient, the gas monitoring line providing a conduit to monitor expelled gases within the passageway and adapted for connection to a gas monitor device;
- whereby the main airway lumen is inserted into the mouth of a patient so that the distal end is positioned in the patient's pharynx and the proximal end remains outside the mouth of the patient.
An oral airway comprising:
- a straight central airway lumen for manipulation of an endoscope or bronchoscope, the straight airway lumen having a distal end and a proximal end;
- an airway passing through the central airway lumen;
- at least one breathing channel positioned adjacent to the central airway lumen;
- a bracket attached to the proximal end, the bracket securing at least one line in which a gaseous substance may flow;
- and
- whereby the line penetrates the breathing channel at the proximal end and the central lumen is inserted into the mouth of a patient so that the distal end is placed in the patient's pharynx and the bracket remains outside the mouth of the patient.
An oral airway system, the oral airway system comprising:
- a central airway lumen having a passageway, the central airway lumen having a proximal end and an opposite distal end;
- a first breathing channel positioned adjacent to the central airway lumen, the first breathing channel having a gas supply line, the gas supply line adapted to supply gas from a gas supply device to the passageway;
- and
- a second breathing channel positioned adjacent to the central airway lumen and opposite the first breathing channel, the second breathing channel having a gas monitoring line for monitoring gases expelled from a patient, the gas monitoring line providing a conduit to monitor expelled gases within the passageway and adapted for connection to a gas monitor device;
- a gas monitoring system connected to the gas monitoring line;
- and
- a gas supply system connected to the gas supply line;
- whereby the airway is inserted into the mouth of the patient so that the distal end is placed in the patient's pharynx and the proximal end remains outside the mouth of the patient, the gases expelled by the patient from the second breathing channel and being sent and analyzed by the gas monitoring system and the gas supply system supplying gas through the gas supply line to the passageway of the first breathing channel.
