Essays on practical medicine and surgery (Volume 2) . r of bellows may be in-serted into one nostril, whilst the mouthand opposite nostril are closed by anassistant, and the windpipe, in the supe-rior prominent part, commonly calledAdams apple, is gently pressed , by forcing air into the lungs, andalternately expelling it by pressing thechest, respiration may be imitated. Inthis way, air may be sent into the lungsabout twenty times in the minute, so asto imitate natural respiration as nearly aspossible. Another, and a more satisfactory methodof insufflation, is, to pass into the larynxa bent silver canula, the larger extremityof which can be attached to the end of aflexible tube, so as to admit of a ready ex-ecution of the process. The finger mustbe passed towards the root of the tongue,on which it must press; in this way, theepiglottis is raised, and, by carrying thecanula along the finger, it readily slidesinto the larynx. To facilitate this opera-tion, Leroy has devised an instrument,represented in the annexed figure, for de-. pressing the tongue and elevating the epi-glottis. This instrument is composed oftwo parts articulated at a, Fig 1 Thebranch b b is fixed; that of c d the extremity c is elevated towardsb, the extremity d is depressed, and ismade to act on the base of the tongue soas to elevate the epiglottis. Fig. 2. represents the canula 1 1 in itsplace. It is attached to the fixed branch ASPHYXIA. (Treatment.) 483 by a ring, /, and at the other end it fol-lows the motions of the other branch, towhich it is attached by another ring, the movement of this branch, and thecorresponding depression of the base ofthe tongue, and elevation of the epiglottis,the canula is directed to the opening ofthe larynx, into which it can be readilymade to enter. Such an instrument, however, can berarely necessary, and it will probably beno more used than the various modifica-tions of the bellows, that have been re-commended by Gorcy, Ruland, Kopp,C
