Vitalograph SafeTway One-Way Valve Mouthpieces

Vitalograph

Description

The SafeTway® mouthpiece allows entry of expired air into the measuring system, but not back to the test subject. This simple, yet effective patented design allays concerns about accidental inhalation of pathogens.
The SafeTway is an inexpensive alternative to the bacterial viral filter for expiratory only testing. It fits most pulmonary function test equipment, including peak flow meters. An adaptor may be required.
The Mini SafeTway with a 22mm diameter mouthpiece is available for paediatric use or for older test subjects who have difficulty fitting their mouth properly around the standard-size mouthpiece.
Other similar generic one-way valve mouthpieces are available from suppliers.
