Abstract: A system and method for verification of nasogastric tube (NGT) placement is provided. A fiber optic light guide includes a proximal end with a light source connection and a distal end having a light emitting tip. The light guide is constructed and arranged for insertion into a lumen of the NGT. A stop that prevents the distal end of the light guide from exiting a distal end of the NGT. The stop is adapted to engage a connector on the proximal end of the NGT. The light emitting tip can comprises a radial emitter. The light source can emit light at approximately 650 nm with an output power of approximately 30W. The stop is located so that the distal end of the light guide is positioned at an offset from the distal end of the NGT when the stop engages the proximal end of the NGT.

Abstract: An oxidizing cleaning composition comprises a low concentration of aqueous hydrogen peroxide that is environmentally friendly and has good stability in strong alkaline solutions. The aqueous hydrogen peroxide composition contains a synergistic combination of one or more hydrophilic surfactants having an HLB of 10 or greater, one or more hydrotropes, one or more UV-analyzable surfactants having an aromatic detectable functional group, and optionally a surfactant having an HLB of less than 10. The cleaning composition when mixed with an alkaline compound is very effective in removing dried or baked residues of polymers, modified or natural celluloses starches, natural gels, and the like at low concentrations and temperatures.
