TwinPhon Transparent (bleu) - 200319

Product features:

• Speaking valve with closed basic position of the silicone membrane
• With additional oxygen supply port
• Adjustable lateral air inlets and outlets can be opened or closed steplessly by rotating through up to max. 90°
  CLOSED: If the air inlets and outlets are closed, the TWINPHON® speaking valves function only in the inhalation direction and behave like a
  normal speaking valve. In this way, the air is routed through the upper airways during exhalation, thus allowing phonation.
  OPEN: Following stepless rotation of the valve in the other direction, the lateral openings are opened again and it is possible to regulate the exhaled air in this way.
• TWINPHON® EXTRA includes an additional HME filter cassette in the rotatable accessory and functions in the opened position like an HME. The HME filter cassette can be replaced and is available separately.

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 closed basic position of the valve creates an air column in the tube during exhalation (in sieved tubes above the sieving) which prevents secretion from penetrating and, consequently, any relocation of the tracheostomy tube
• 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!)
• Weaning/ Speech therapy

TwinPhon Extra Transparent (bleu), valve phonatoire réglable pour patients trachéotomisés.

• valve phonatoire avec position standard fermée
• équipée d'un raccord d'oxygène supplémentaire
• avec ouvertures d'air réglables pour une résistance respiratoire modulable
• peut être équipée d'une cassette HME (REF 200317)

Valve phonatoire avec membrane en silicone de haute qualité et position standard fermée. Équipé d'un raccord d'oxygène supplémentaire. Les ouvertures d'air réglables rendent cette valve phonatoire multifonctionnelle. En position fermée, le TwinPhon fonctionne comme une valve phonatoire normale. En tournant les ouvertures d'air selon besoin, la résistance respiratoire est réglée et il est facile d'expirer par la valve.

En utilisant une cassette HME TwinPhon (REF 200317), le TwinPhon peut également fonctionner comme HME.
