Combiphon is a compact, transparent speaking valve with a silicone membrane. The Combiphon speaking valve enables tracheostomised patients with an intact larynx to speak.
The special feature of this speak- ing 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 is simply attached to either a 15-mm connector or 22 mm combi- adapter 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 inspira- tion. The exhaled airflow causes the valve to close, which enables speech.
The transparent valve housing offers an unobtrusive appear- ance. The Combiphon O2 speaking valve, has a lateral port (ISO plug-in con- nection 5 mm), which enables the connection to an oxygen device, if required.
The use on laryngectomised patients is contraindicated. The Combiphon speaking valve is supplied in individual, sterile packag- ing. The Combiphon speaking valve is a single-patient product.
