The SDI Diagnostics Spirotubes are premium, single-use cardboard mouthpieces designed for standard pulmonary function testing and spirometry screenings. Engineered with precision-cut, smooth edges to maximize patient comfort and eliminate tissue irritation, these disposable tubes provide a clean, secure lip seal during forced expiratory maneuvers. The structural design features an optimized wall thickness that resists bending or collapsing under firm teeth clenching, ensuring an unrestricted airway for highly accurate flow and volume measurements. These mouthpieces serve as a cost-effective, hygienic barrier that protects the internal sensor mechanics of the testing device from heavy moisture accumulation, while completely eliminating the time-consuming sterilization procedures required for reusable parts between patient appointments.
