Abstract:
1. A pharyngeal intubation guiding device comprising: tongue-side and palate-side walls which extend in a lengthwise direction, and which are spaced apart from each other in a transverse direction that is a direction transverse to the lengthwise direction to define a guiding duct, said tongue-side wall having first entry and locating ends opposite to each other in the lengthwise direction, and first prepharyngeal and postpharyngeal segments extending respectively from said first entry end and first locating ends and towards each other to form a first juncture region which is configured to conform to the rear end of a patient's tongue such that said first locating end is brought to engage the front of the patient's epiglottis to thereby permit said guiding duct at said postpharyngeal segment to confront the opening of the patient's larynx, said palate-side wall having second entry and locating ends which are opposite to each other in the lengthwise direction, said second entry end cooperating with said first entry end to define an access opening which is in spatial communication with said guiding duct, said second locating end being configured to disposed at the opening of the patient's larynx to serve as a barrier between the larynx and the esophagus of the patient when said first locating end is engaged with the front of the patient's epiglottis, and second prepharyngeal and postpharyngeal segments extending respectively from said second entry end and said second locating end and towards each other to form a second juncture region which is configured such that an outer contour of said second prepharyngeal segment establishes a guideway towards the opening of the patient's esophagus; a laryngoscope guiding channel which is disposed in said guiding duct, and which extends from said first postpharyngeal segment to said first prepharyngeal segment and through said access opening; a viewing window which extends between said first and second postpharyngeal segments in the transverse direction so as to define a terminal end of said laryngoscope guiding channel that is located upstream of said first locating end; an endotracheal tube guiding groove which is disposed in said guiding duct, and which extends from said first locating end along said first postpharyngeal and prepharyngeal segments and to a lead-in port which is configured to be located laterally and outwardly of said access opening so as to permit an endotracheal tube introduced therein to be removable laterally between said first and second prepharyngeal segments; and a partition wall which extends between said tongue-side wall and said palate-side wall and in the lengthwise direction to divide said guiding duct into said laryngoscope guiding channel and said endotracheal tube guiding groove; said palate-side wall including channel-side and groove-side wall sections which are attachable to each other along a joining line extending in the lengthwise direction, said channel-side wall sections confronting said tongue-side wall in the transverse direction to define said laryngoscope guiding channel, said groove-side wall section confronting said tongue-side wall in the transverse direction to define said endotracheal tube guiding groove.
