Vitalograph SafeTway 1-Way Mouthpiece x 200

SafeTway mouthpieces are disposable, one way valves that allow entry of expired air into the measuring system but not back to the test subject. This simple yet effective patented design prevents concerns of accidental inhalation of pathogens. These low cost and low resistance mouthpieces help to prevent cross-infection and can be used with most peak flow meters and spirometers.

It has a 30mm diameter at both ends, and fits most pulmonary function test equipment, including peak flow meters. An adaptor may be required for some models not accepting 30mm diameter mouthpiece.

Features:

Protects the subject from cross-infection
One-way valve prevents inhalation respiratory manoeuvre
Suitable for expiratory manoeuvres with peak flow meters and spirometers
Attractively priced and completely disposable
