Mouthpiece for Peak Flow Meter

The low cost, low resistance mouthpiece allows entry of expired air into the measuring system, but not back to the test subject. This simple, yet effective design prevents concerns of accidental inhalation of pathogens.

This 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.

• For use with peak flow meters and spirometers.
• One-way valve prevents accidental inhalation.
• Completely disposable.
• A low cost alternative to BVF for expiratory testing.
