PRIMEDI-PHON PLUS®
SPEAKING VALVES FOR TRACHEOSTOMIZED PATIENTS
Product features:
- Speaking valve with closed basic position of the silicone membrane
- Available in two different colour schemes:
TRANSPARENT: suitable for the use in the outpatient sector and for home care, due to its unobtrusive colour scheme
BLUE-TRANSPARENT: designed for use with inpatients, due to its conspicuous colouring
- Available with or without integrated oxygen supply port
- The filter cartridge contained in the scope of delivery can be optionally connected to the PRIMEDI-PHON PLUS® speaking valve for filtering inspiration air (also available separately)
Suitable for the following:
- Tracheostomy tubes with and without sieving
- Tracheostomy tubes with completely unblocked cuff and tracheostomy tubes without cuff
(IMPORTANT: An adequate airflow around the tracheostomy tube must be ensured!)
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 impermeability of the PPP speaking 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
(The use on laryngectomized patients is contraindicated!)
