Corrugated Systems Corrugated tubing ensures light weight, an advantage against drag and pressure on the patient. The shallow corrugations minimise flow resistance and turbulence, ensuring accurate flow rates. Argentic Systems Argentic circuits are anti-microbial breathing systems that combat microbial contamination within the clinical setting and reduce the risk of hospital acquired infections. Argentic breathing circuits are impregnated with a silver ion additive. When oxygen in the ambient air comes into contact with silver particles, it creates a catalytic reaction which helps deactivate microbes. Smoothbore Systems The smooth inner side of the tubing reduces turbulence, flow resistance and work of breathing in comparison with some corrugated tube circuits. The kink resistant spiral outer ribs support tube patency ensuring exact delivery of breathing gases Flexi-Lock Systems Expandable circuit for greater flexibility within the operating room or for patient transport. The circuit can be expanded to the desired length and curved into specific positions without the need for tying down.
