US 2014/0275784 A1 · CONSCIOUS SEDATION AIRWAY

Abstract

A conscious sedation airway, CSA, useable during conscious or unconscious sedation. The CSA includes an elongate body with an anterior flange depending therefrom. The body includes a central portion with superior and inferior plates extending a distance beyond a distal end of the body in an inferiorly curved arrangement. A midline opening and two lateral openings extend through the length of the central portion and are configured to receive apparatus, like endoscopes, cannula, and catheters. The superior and inferior plates aid to maintain a position of the tongue and to guide apparatus inserted through the midline opening toward the posterior oropharynx. The anterior flange prevents swallowing the CSA. The body does not extend into the pharynx to enable use in conscious patients and/or those with intact gag reflexes. And a nasopharyngeal airway can be placed without removing the CSA to allow bag ventilation of the patient.

Dependent claims

A conscious sedation airway (CSA) apparatus for insertion into the mouth of a patient, the CSA comprising:

an internal body having a distal end that is insertable into the mouth of the patient;
an opening extending through the internal body and substantially parallel to the length of the internal body;
a superior projection extending from the distal end of the internal body and positioned superior to the opening;
and
an inferior projection extending from the distal end of the internal body and positioned inferior to the opening, the inferior projection configured to contact the tongue of the patient to resist movement of the tongue toward the posterior oropharynx.

A conscious sedation airway (CSA) for insertion into the mouth of a patient, the CSA comprising:

an internal body having a distal end that is disposable in the mouth;
a midline opening extending through the internal body and substantially parallel to a long axis of the internal body;
a secondary opening extending through the internal body substantially parallel to the midline opening, the secondary opening having a diameter that is smaller than the diameter of the midline opening;
a superior projection extending outwardly and downwardly from the distal end of the internal body and positioned superior to the opening;
an inferior projection extending outwardly and downwardly from the distal end of the internal body and positioned inferior to the opening, the inferior projection configured to contact the tongue of the patient to resist movement of the tongue toward the oropharynx, the superior projection and the inferior projection terminating anterior to the oropharynx of the patient when the internal body is disposed in the mouth;
and
an anterior flange depending from an anterior end of the internal body, the anterior flange configured to abut the patient's lips and to resist swallowing and inhalation of the CSA by the patient.
