Anesthesia Circuit with Coaxial tube
Coaxial Anesthesia Breathing Circuit with CE
Product Overview
The Coaxial Anesthesia Breathing Circuit is a single-limb breathing system designed for gas delivery during surgical anesthesia and critical care ventilation. It adopts a tube-within-a-tube structure — the corrugated inner tube delivers fresh gas to the patient, while warmed expired gas exits through the outer tube. This coaxial design reduces surgical field clutter, eliminates limb twisting, and provides natural heat and moisture conservation for inhaled gases.

Key Benefits for Medical Distributor
Heat & Moisture Conservation: Warm expired gas in the outer tube pre-heats fresh gas in the inner tube, reducing airway heat and moisture loss — especially critical in pediatric cases and surgeries exceeding 2 hours.
Simplified Surgical Field: Single-limb design replaces the conventional dual-tube setup, reducing the risk of accidental tugging, kinking, or disconnection around the operating table.
Secure Inner Tube Design: Inner tube is heat-welded at connection points, preventing slippage or detachment during use. High kink-resistance material maintains gas pathway integrity under normal bending conditions.
Real-Time CO₂ Monitoring: Patient-end elbow with integrated luer port supports end-tidal CO₂ sampling without requiring additional adapters.
Global Compliance: CE certified under MDR framework, manufactured under ISO 13485 quality management system, with full biocompatibility testing per ISO 10993.
FAQ
Q: What is the advantage of a coaxial circuit over a conventional dual-limb circuit?
A: The coaxial design integrates both inspiratory and expiratory pathways into a single tube, cutting visible tubing in half. This reduces workspace clutter and lowers the risk of accidental disconnection. The tube-within-a-tube structure also provides passive heat and moisture exchange, which a conventional dual-limb circuit cannot offer without adding a separate HME device.
