Abstract
An intubation instrument has an abraded and adsorbent sheath that is telescoped both internally and externally of a tube. The sheath is provided with a handle to facilitate retraction thereof as the tube is inserted into a body cavity, thereby minimizing transportation of pathogens into the body.
