Product Description


COMBIPHON® O2 Speaking Valve

Combiphon® is a compact, transparent speaking valve with a silicone membrane. The Combiphon®O2 speaking valve, has a lateral port (ISO plug-in connection 5 mm), which enables the connection to an oxygen device, if required.The Combiphon® speaking valve enables tracheostomised patients with an intact larynx to speak. The special feature of this speaking valve is the basic position of the valve membrane. It is closed and is briefly opened during inspiration. This makes the increased pressure for closing the valve, otherwise required to form speech, unnecessary. It can be attached to either a 15-mm connector or 22 mm combiadapter of e.g., the Duravent®/Duracuff®/Duratwix® tracheostomy tubes. This makes the Combiphon® speaking valve perfectly suited for use in combination with fenestrated/sieved Duravent®, Duracuff® and Duratwix® tracheostomy tubes, as well as other tube systems. Like in the Duravent® silicone speaking valve, the valve flap opens on inspiration. The exhaled airflow causes the valve to close, which enables speech. The transparent valve housing offers an unobtrusive appearance.

The Combiphon®O2 speaking valve, has a lateral port (ISO plug-in connection5 mm), which enables the connection to an oxygen device, ifrequired.

The O2 connector/port is conical shaped. The dimensions are 4.5 mm as largest and 3.5 mm as smallest diameter.
The inner diameter of the small protective closing cap which sits on the O2 connector/port has an inner diameter of 5mm.
Therefore the corresponding O2 supply tube should also have an inner diameter of 5 mm.

The use on laryngectomised patients is contraindicated.
