Novel system for providing lubricity to the surface of a nasogastric intubation device, which system comprises a substantially homogeneous mixture consisting essentially of: (1) an effective amount of an unsaturated higher fatty acid having at least 16 carbon atoms; and (2) a polymer compatible therewith. The mixture may be coated on the surface of the portion of the length of the tube assembly to be lubricated or, alternatively, the acid may be contained in the polymer mix employed in the manufacture of the tube assembly. When the acid-containing surface is contacted with an aqueous alkaline solution prior to intubation, the acid is converted to the corresponding lubricious soap.

A nasogastric intubation device including a flexible hollow tubing adapted for insertion through the nose, said device having a leading end portion adapted for positioning in the stomach and a trailing end to remain outside the body and through which stomach fluids may be withdrawn or into which fluid may be fed, at least said leading end portion containing a lubricious precursor composition consisting essentially of a substantially homogeneous mixture of from about 20 to about 60 percent by weight based upon the total weight of said composition of an unsaturated higher fatty acid having at least sixteen carbon atoms and a polymer compatible therewith, said precursor upon contact with an aqueous alkaline medium forming the lubricious salt of said higher fatty acid whereby to lubricate the surface of said portion containing said precursor composition.
