Abstract
An adhesive device retains a medical tube, and particularly a naso-gastric tube, in relation to a patient with improved flexibility, strength and adhesion. The device includes a nose pad portion for attaching to a patient's nose and a tube attachment section for attaching to the naso-gastric tube. A substantially inelastic spine extends across a narrow or otherwise vulnerable neck portion, which connects the nose pad to the tube attachment section. The spine strengthens the retaining device against tensile and shear forces while allowing flexibility. At the same time, deflection of the spine does not cause internal elastic stresses sufficient to counter adhesion of the retainer to either the patient or the medical tube.
