Abstract
An adjustable ventilation interface for a continuous positive airway pressure system includes a nasal cannula body. The nasal cannula body includes a pair of nasal prongs that are adjustable with respect to each other. The nasal prongs are located on a top portion of the nasal cannula body to create a sealing interface between the nasal cannula body and a nose. Another sealing interface is provided by a bellows-like structure integrally molded in a portion of the nasal cannula body. The bellows portion acts as a compression spring; thereby creating an adjustable sealing between the nasal cannula body and the nose.
