ABSTRACT:
The composite intubation tube has an outer pliable outer layer of plastic material and an inner concentric layer made of a hydrophilic polymer which becomes very soft and flexible in a wetted state. After intubation in a patient, a flow of gastric fluids or an inflow of nutrient solution wets the inner layer to become very soft so that pressure points on the tissue of the patient are eliminated.
