One-way valves ensure “infection protection”

The Safe-t-Chek™ mouthpieces adapt to all spirometers, peak flow meters and other PFT devices! Its innovative design virtually eliminates the threat of cross-infection. Patients worry about getting germs from others — now they can relax with Safe-t-Chek™. The unique 8-point peripheral support creates a complete seal, as the valve closes completely if the patient attempts to inhale. This interrupts air flow, preventing the passage of airborne infectious particles. Keep your patients safe...with Safe-t-Chek™!
