HI-501

The HI-501 disposable spirometry mouthpiece is an essential accessory for professional pulmonary function testing using CHEST devices. Manufactured with high-quality white spiral cardboard and assembled with non-toxic adhesive, these mouthpieces provide a reliable interface for respiratory diagnostics. Key specifications include a length of 60 mm, an internal diameter of 28 mm, and an external diameter of 30 mm, ensuring an airtight fit with the compatible CHEST model HI-501 hardware. The satin exterior finish enhances patient comfort throughout the procedure. As a single-use medical device, these mouthpieces are designed to prevent cross-contamination between patients. Professional medical facilities must utilize one mouthpiece per patient to maintain hygiene standards and clinical safety protocols.
