DescriptionCarefusion MicroLab One-Way Disposable Mouthpieces. Effective cross infection control during expiratory manoeuvres. The low cost, low resistance one-way 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. Protects the subject from cross-infection. One-way valve prevents inhalation respiratory manoeuvre. Suitable for expiratory manoeuvres with peak flow meters and spirometers.
