This is a behind-the ear padding innovation for nasal cannula. This page will provide 3D models and drawings of the part.
3D models of a type of behind-the-ear protective padding for oxygen tubing. This model improves on the original by use of a helix design that adheres to the tubing more securely. A unique deviation from helical structure near the ends allow for more facile application. Dimensioned drawings are also provided.
