To this extremityis attached a piece of elastic tubingabout six inches in length, with a stop-cock at its free end. The canula havingbeen introduced into the trachea, the beltis inflated by means of the tube, and thestop-cock turned off. The expansion ofthe belt blocks up the space between the canula and the walls of the tra-chea, and thus renders it impossible for any blood to pass from the larynxinto the air-passages. It is very important not to fill the air-belt too full, 1 Monatsschrift fur Ohrenheilkunde, 1879, No. 6. 2 Deutsche Zeitschrift fur Chirurgie, 1872, p. 406. 3 In Trendelenburgs original instrument, the capillary tube was soldered to theoutside of the canula, and rendered the latter very difficult of introduction. improvement consists in placing the fine tube within the Fig. 107.—Semons Modification of Tren-delenburgs Tampon-canula. 378 DISEASES OF THE PHARYNX, LARYNX, AND TRACHEA. as much pressure suddenly applied to the trachea is apt to produce anasthmatic paroxysm.
