Abstract
Abstract A removable, disposable tracheotomy obturator of soft, plastic material, of the type having a valve plug connected by a flexible strap to a valve cap, normally positioned within a curved tracheotomy tube, is provided with windpipe means to permit the patient to breathe freely while the tube is being inserted during a tracheotomy. The windpipe means may be air passages in the plug and in the cap or may be a continuous, air conduit of soft plastic extending from a blunt, terminal tip in advance of the plug, through the tube and cap to ambient atmosphere. Inflexible proximal portions are provided on the attachment ears of the tube as a means of suspended fixation of the tube as a bridge over the incision.
