The general character of the tubes and instruments is shown inthe illustrations (Figs. 85 to 89). The tubes for false membrane are hollow cylinders in graded sizesof just sufficient length to reach beyond the cricoid constriction andare for temporary use only to allow the expulsion of the detached mem-brane when this is suspected to be present. They should on no accou nt27 4 IN INFECTIOUS DISEASES Fh;. 87. ODwyers intubation set in case. DIPHTHERIA 419 be left in position for longer than an hour or two, as, unlike the regulartubes, they are not adapted to the anatomy of the larynx. Special tubes with built-up heads are occasionally used with theobject of riding over the granulations caused by the disease and thuspromoting their absorption. Fig. 90
