More Information
Summary:A nasopharyngeal tube is disclosed which is inserted via the nasal cavity for the maintenance of the airway in emergency medicine and post anaesthesia. The nasopharyngeal tube 5 comprises an oxygen elbow 1 and oxygen elbow connector 2 at its proximal tip to allow oxygen delivery to the tube 5. The elbow 1 and elbow connector 2 act as a stop to prevent the device slipping into the lower airway. The elbow 1 and elbow connector 2 provide an oxygen inlet 6 and exhalation port (7, Figure 3). A series of small holes act 4 at the distal end of the tube act as humidification vents. A respiratory indicator can be provided wherein a monitoring line (9, Figure 5) is fixed into the exhalation port 7 of the oxygen elbow 1. The distal tip (8, Figure 5) of the line 9 is located above the vents 4 to allow carbon dioxide to be detected.
