Oxygenating bite block

An endoscopic bite block, comprising:

• a base having a body including a recess configured to engage upper and lower teeth of a patient, the base having a central passageway extending through the body, the central passageway extending between the upper and lower teeth and into a mouth of the patient when the body is encapsulated by lips of the patient, the central passageway configured to receive an endoscope;
• an elongated guide having a longitudinal curvature corresponding in shape to an oral-pharyngeal cavity of the patient, the elongated guide protruding from the base toward a retropharyngeal space of the patient, the elongated guide having a lateral curvature for guiding the endoscope along the longitudinal curvature of the elongated guide;
• a flange at an end of the base opposite the elongated guide, the flange having a first opening, a second opening, and a central opening disposed between the first opening and the second opening;
• an oxygen inflow tube integral to the elongated guide and configured to receive oxygen gas from an oxygen source;
• and
• a secondary tube configured to receive gas from a gas source,
• wherein the oxygen inflow tube and the secondary tube are configured to be introduced through the same opening of the first and second openings of the flange and extend from the base along opposite sides of the elongated guide.

An endoscopic bite block kit, comprising:

• an endoscopic bite block having a base, an elongated guide, a flange, an oxygen inflow tube, and a secondary tube, wherein:
• the base includes a body and a central passageway extending through the body, the central passageway extending between teeth and into a mouth of a patient when the body is encapsulated by lips of the patient, the body having a recess configured to engage the teeth of the patient, the central passageway configured to receive an endoscope,
• the elongated guide includes a longitudinal curvature corresponding in shape to an oral-pharyngeal cavity of the patient,
• the elongated guide protrudes from the base toward a retropharyngeal space of the patient,
• the elongated guide includes a lateral curvature for guiding the endoscope along the longitudinal curvature of the elongated guide,
• the flange, positioned at an end of the base opposite the elongated guide, has a first opening, a second opening, and a central opening disposed between the first opening and the second opening,
• the oxygen inflow tube is integral to the elongated guide and is configured to receive oxygen gas from an oxygen source,
• the secondary tube is configured to receive gas from a gas source, and
• the oxygen inflow tube and the secondary tube are configured to be introduced through the same opening of the first and second openings of the flange and extend from the base along opposite sides of the elongated guide;
• and
• a gas tube configured to couple to at least the oxygen inflow tube or the secondary tube of the endoscopic bite block at a first end of the gas tube and configured to couple to at least the oxygen source or the gas source at a second end of the gas tube.

An endoscopic bite block, comprising:

• a base having a body and a flange, a central passageway extending through the body, the body configured to be encapsulated by lips of a patient thereby keeping a mouth of the patient open during a medical procedure, the central passageway extending between teeth and into the mouth when the body is encapsulated by the lips, the central passageway configured to receive an endoscope, the flange dimensioned to preclude the flange from entering an oral cavity of the patient;
• an oxygen inflow tube protruding from the base and configured to receive oxygen gas from an oxygen source;
• a secondary tube configured to receive gas from a gas source;
• and
• an elongated guide protruding from the base, wherein the elongated guide is configured to guide the oxygen inflow tube to a retropharyngeal space of the patient, wherein:
• the flange having a first opening, a second opening, and a central opening disposed between the first opening and the second opening,
• the oxygen inflow tube protrudes from the base in a same direction as the elongated guide,
• the oxygen inflow tube is configured to supply the received oxygen gas to the retropharyngeal space of the patient,
• the oxygen inflow tube and the secondary tube are configured to be introduced through the same opening of the first and second openings of the flange and extend from the base along opposite sides of the elongated guide, and
• the elongated guide includes a longitudinal curvature corresponding in shape to an oral-pharyngeal cavity of the patient and a lateral curvature for guiding a medical device along the longitudinal curvature, thereby protecting a throat passageway of the patient.
