Product features:

• Speaking valve with closed basic position of the silicone membrane
• With integrated oxygen supply port
• Particularly flat design (low profile)
• With 15 mm connector
• Available in five different colour schemes
• Thanks to its special shape, the speaking valve is not bulky and offers particular freedom of movement.
  It is therefore also ideal for use with children.
• Enables particularly effective phonation

How does it work?

• A special feature of this speaking valve is the closed basic position of the silicone membrane
• The membrane only opens briefly during inspiration and reacts to even very weak inhalation
• Afterwards it automatically returns to the tightly sealed basic position without exhalation pressure (expiration pressure) being required (an extremely short shutting time); phonation therefore does not require any build-up of expiration pressure
• The expiration air is channelled completely via the larynx and upper respiratory tract
• This enables the formation of speech (phonation) and expectoration of secretions

Indication

• Spontaneously breathing tracheostomized patients with sufficient tidal volume (adults & children).
  (The use on laryngectomized patients is contraindicated!)
