Product Details
The expiratory valve controls the discharge of exhaled gas during
ventilator operation, ensuring smooth exhalation while preventing
external air from flowing back into the ventilator circuit. It
maintains normal pressure and gas flow direction in the respiratory
loop.
Made of medical-grade plastic or metal, featuring excellent
biocompatibility, corrosion resistance, and durability to meet
medical environment requirements.
Designed with standard interfaces for connecting to ventilator
breathing circuits and the main unit, ensuring tight and airtight
connections. Common methods include threaded or snap-fit
connections.
- Sealability: Effectively prevents gas backflow during exhalation.
- Expiratory Resistance: Moderate resistance to avoid hindering patient exhalation, while
maintaining pressure stability in the respiratory loop in
conjunction with the ventilator's overall performance.
- Flow Adaptability: Adjusts to different exhalation flows of patients.
