Datex Ohmeda GE Healthcare | Advanced Carestation Anesthesia Delivery System Component | Breathing Circuit Gas (BCG) Architecture | Model 1406-3390-000 | Regular Circle Module Assembly | Patient Expiratory & Inspiratory Limb Manifold

The Datex Ohmeda 1406-3390-000 is a professional-grade, high-precision anesthesia delivery component engineered as the core Regular Circle Module Assembly for the Breathing Circuit Gas (BCG) system found within premium GE Healthcare Aestiva, Aespire, and Aisys anesthesia carestations. Functioning as the centralized structural manifold for patient gas circulation, this module assembly integrates the inspiratory and expiratory limbs into a single, compact, and completely leak-proof block. It houses critical internal pneumatic paths, including check valve seats, disk retainers, lens circuits, and drain button channels, to ensure unidirectional gas flow during ventilation. Precision-molded from high-performance, medical-grade, chemically resistant polymers, this assembly ensures consistent fresh gas delivery, effective waste gas elimination to the scavenging network, and stable control over low-flow fresh gas delivery loops, minimizing resistance changes across dynamic inhalation and exhalation cycles.
