The safety of bronchoscopic or esophagoscopic examination of newborn infants depends on the employment of small caliber instruments. The use of a new miniature lamp and lamp carrier has made possible a significant decrease in the external diameter of the infant bronchoscope and esophagoscope herein described, without decreasing the working lumens.
The lamp, 1.7 mm. in diameter and 15 mm. in over all length, is detachable from its carrier. The carrier and the lamp are of the same diameter and rest in a grooved channel, whose sides are carried into the lumen of the bronchoscope just far enough to hold them in place throughout the length of the tube.
The bronchoscope is of the Chevalier Jackson type,1 3.5 mm. in internal diameter, 5.5 mm. in external diameter and 25 cm. or 30 cm. in length. The unusual smoothness of the distal tip of the instrument permits easy introduction of the
