Product Overview The Schiller Spirometer Mouthpiece is a single-use disposable patient mouthpiece designed for use with the Schiller SP-150 and SP-250 Flow Sensor Spirometers. The mouthpiece interface ensures every patient gets a clean, dedicated touchpoint with the spirometer’s flow sensor. For pulmonary function workflows, single-use mouthpieces are an essential infection-control component: each patient breathes through their own dedicated piece, removing the need to reprocess the contact element between visits. This supports the safety standards expected in respiratory testing across primary care, occupational health, and pulmonology workflows. The package contains 10 mouthpieces per pack, sized for clinic-day stocking. Note that the Schiller flow sensors themselves are not included — these mouthpieces interface with an existing SP-150 / SP-250 device. Pairing genuine Schiller mouthpieces with the manufacturer’s flow sensor helps ensure the calibration and flow profile the spirometer was tested for, supporting accurate FEV1, FVC, and PEF measurements.
