Protect your patients and equipment from contamination with the Peak Flow Meter Accessories including economical, disposable mouthpieces and single patient use filters and masks. The disposable one-way-valved and single patient use mouthpieces, filters and masks are designed to provide protection against possible cross infection in common respiratory procedures.

The expiratory (red) one-way-valved mouthpiece fits standard peak flow meters and spirometers for expiratory use. The patient can exhale forcefully into the peak flow meter or spirometer, and the one-way-valve prevents inhaling through the mouthpiece or equipment attached to. The inspiratory (blue) one-way-valved mouthpiece provides protection in inspiratory procedures. The patient can inhale freely through the mouthpiece on the In-Check or In- Check DIAL, and the one-way-valve prevents the patient from exhaling into the meter.

Single Patient Use Adult and Pediatric Mouthpieces are an excellent choice when cross contamination is not a concern. The high quality disposable mouthpieces have a non-absorbent finish and do not stick to the lips. This provides greater comfort for adults and pediatrics.
