A VALVE ACCESSORY FOR AIDING SPEECH DURING NON-INVASIVE RESPIRATORY THERAPY

摘要

A valve arrangement interposed between a compressor and a user, in a respiratory pressure support system. A connecting element connects a breathing tube to a human interface apparatus. A shutter is formed within the connecting element. The shutter is placed in a first position allowing pressurized air to flow from the compressor to the user. This shutter is placed in a second position preventing pressurized air from flowing from the compressor to the user.
