Indications for Use

The Hudson Heated Wire Ventilator Circuit is intended as a conduit for respiratory gas between a patient and a ventilator, and includes heated wires for use with a Concha Column Humidifier; the heated wires are intended to minimize condensation in the ventilator tubing.

Device Story

The Hudson RCI Heated Wire Ventilator Circuit serves as a conduit for medical gases between a ventilator and an adult patient. It connects to an endotracheal or tracheostomy tube. The device incorporates heated wires powered by a 21-volt ConchaTherm controller to minimize condensation within the ventilator tubing. The circuit consists of corrugated tubing, connectors, and a wye piece. It is operated by healthcare professionals in clinical settings. The device is designed to improve patient care by preventing moisture accumulation in the airway circuit. The subject device modifies the predicate by changing the adapter design (from single-piece to two-piece), reducing length to 1.52 meters, and upgrading the heated wire harness from single-strand to seven-strand for improved durability and performance.

Clinical Evidence

Bench testing only. Performance testing conducted per ISO 5367 standards, including measurements for inspiratory/expiratory resistance at various flow rates (30-120 LPM), compliance at 60-110 cmH2O, and leak rates. Results confirm the device meets specifications for its intended use.

Technological Characteristics

Materials: High-density polyethylene, low-density polypropylene, polyethylene/EVA blend, PVC, copper/nickel conductors, phosphor bronze connectors. Sensing/Actuation: 21-volt heated wire system for condensation control. Dimensions: 1.52 meters. Connectivity: Compatible with Hudson RCI 21-volt heated wire humidifiers. Sterilization: Not specified. Standards: ISO 5367 for resistance and compliance testing.

Indications for Use

Indicated for adult patients requiring respiratory gas delivery via a ventilator. Contraindicated for use on bare skin or when incompatible with humidifier electrical requirements.

Regulatory Classification

Identification

A respiratory gas humidifier is a device that is intended to add moisture to, and sometimes to warm, the breathing gases for administration to a patient. Cascade, gas, heated, and prefilled humidifiers are included in this generic type of device.
