A laryngoscope (10) includes a tubular laryngoscope blade (12) which is curved in the manner shown in Fig. 2 and provided with a slot along its length. The blade is tubular throughout its entire length except for an end tip (20) which serves to elevate the epiglottis of a patient when the blade is inserted into the pharynx and larynx of the patient. The tubular and slotted nature of the blade permits an endotracheal tube to be inserted in an open end (22) of blade (12) and to be guided along the blade so that the tube can emerge near tip (20) after the blade has been inserted into the throat of a patient. This allows the tube to enter the patient's trachea for intubation as is well known. The tube is curved to permit it to follow the conformation of the throat and to facilitate insertion of blade (12) into the throat prior to intubation. The blade could also be of a material which is normally rigid but can be flexed or shaped to fit different throat configurations. A laryngoscope handle (25) containing a battery for energizing a light source can be coupled to base member (24). The light source may be located in the handle or in the base member. Light passes via fibre optic guides (46) into the larynx which can be viewed via eye piece (78) and fibre optic guide (74). |
