Product Overview The Intersurgical Straight Connector is a respiratory-circuit adapter sized at 15 mm to 22 mm internal diameter, designed to bridge two airway components in a ventilator, anesthesia, or oxygen delivery circuit. The straight, in-line geometry preserves the shortest possible airflow path between connected components. The connector is appropriate for use in adult and pediatric airway circuits across hospital, surgery, and EMS environments. Common applications include connecting a heat-and-moisture exchanger to a breathing circuit, bridging a catheter mount to a tracheostomy tube, or extending a circuit to accommodate patient positioning. The 15 mm female to 22 mm male standard interface complies with ISO airway-component sizing, providing broad cross-compatibility with anesthesia masks, ventilator circuits, HMEs, filters, mainstream capnography sensors, and supplemental oxygen accessories produced by major airway-equipment manufacturers. Each connector is single-patient use and supports clean, modular respiratory-circuit assembly. Intersurgical is a recognized manufacturer of breathing-circuit components, and this connector is HCPCS-coded under A4618 for tubing-and-accessory billing where applicable.
