Intended Use

The Hudson RCI Dri-Tech Breathing Circuits are intended for pediatric and adult patients in professional healthcare environments as a conduit of breathing gas between a patient and a ventilator and to maintain the temperature of humidified inspired gas.

Device Story

Dri-Tech Breathing Circuits serve as conduits for respiratory gas between ventilators and patients (pediatric/adult). Circuits include integrated heated wires to maintain gas temperature and reduce condensation, used in conjunction with the Hudson RCI Neptune Heated Humidifier. Components include inspiratory/expiratory limbs, tubing adaptors, hangers, and optional accessories (filters, pressure monitoring lines). Used in professional healthcare environments; operated by clinicians. Output is the delivery of warmed, humidified gas to the patient's airway (via tracheal tubes or masks). Clinical benefit is the maintenance of airway humidity/temperature and prevention of condensate pooling. Device is disposable (12-day useful life).

Clinical Evidence

No clinical testing was performed. Substantial equivalence is supported by bench testing, including biocompatibility (ISO 10993-1:2018, ISO 18562-1:2017), electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and mechanical performance (ISO 5367:2014, ISO 5356-1:2015).

Technological Characteristics

Heated wire breathing circuit; 19mm ID inspiratory limbs; 22mm conical connectors (ISO 5356-1:2015). Materials evaluated for biocompatibility per ISO 10993-1 and gas pathway safety per ISO 18562-1. Powered by external humidifier controller. Non-sterile, single-patient use. Compliant with ISO 5367:2014, ISO 80601-2-74:2017, and IEC 60601-1.

Indications for Use

Indicated for pediatric and adult patients in professional healthcare environments as a conduit for breathing gas between a patient and a ventilator, including heated wires to maintain gas temperature and minimize condensation. Not indicated for neonates or infants.

environments as a conduit for respiratory gas between a patient and includes heated wire(s) for use with the Hudson RCI Neptune Heated Humidifier (K131912). The heated wires are intended to aid in maintaining the set patient temperature and minimize condensation in the ventilator tubing.

The Dri-Tech Breathing Circuits are designed to be used with various patient interfaces such as oral tracheal tubes, nasal tracheal tubes, endo-bronchial tubes, and masks (for noninvasive ventilation therapies such as CPAP, BiPAP, and Mask usage). As such, Dri-Tech Breathing Circuits are designed and will be manufactured to conform to the test requirements of ISO 5367:2014 "Anaesthetic and respiratory equipment -- Breathing sets and connectors".

The adult dual limb configuration consists of 19mm ID inspiratory limbs with 22mm connectors that are compliant to ISO 5356-1.2015 Anaesthetic and respiratory equipment – Conical connectors – Part 1: Cones and sockets. The adult circuits have a length of 1.7m on the inspiratory limb, and are kitted with the accessories described below:

- Tubing Adaptor: 22mm male to male adaptor for various connections as required.
- . Elbow Adaptor: Adaptor for connecting to the circuit wye to the patient interface to allow the circuit to exit the patient perpendicularly for optimal placement.
- . Tubing Hanger: Optional accessory for hanging the circuit to reduce pull on the patient interfaces and ventilator/humidifier connections.
- . Humidifier Limb: Required tubing and adaptors for connecting the ventilator inhalation port to the heated humidifier.

Optional Ventilator Accessory available for the Dri-Tech Dual Limb Breathing Circuit:

- . Dri-Tech Ventilator Accessory: Optional tee accessory capable of providing the 10 LPM flow required for the expiratory star lumen tubing. This ventilator accessory is comprised of male and female medical grade air DISS connectors to connect between the air hose and ventilator, a standard Christmas tree adaptor for connecting the tubing to, and an on/off valve to start and stop the flow.
The adult single limb configuration is identical to the inspiratory limb of the dual limb configuration, however, is packaged with a different set of adaptors to facilitate connections and use with non-invasive therapies as described below:

- Humidifier Line: Optional tubing and adaptors for connecting the ventilator inhalation port to the heated humidifier.
- Exhalation Port Adaptor: Optional adaptor including an exhalation port and connector for the pressure monitoring line.
- Pressure Monitoring Line: Optional accessory tubing for use with units without an Airway Pressure Monitor.
- Pressure Monitoring Assembly: Optional accessory containing a tee and tubing for pressure monitoring on units with an Airway Pressure Monitor.
- 15mm Adaptor: Optional accessory required for connecting to certain patient interfaces.
- Male Luer: Optional accessory for required for certain setups to connect the pressure monitoring line.
- Tubing Hanger: Tubing hanger designed for single limb tubes and pressure monitoring lines to reduce pull on the patient interfaces and ventilator/humidifier connections.

#### Indications for Use

The Hudson RCl® Dri-Tech Breathing Circuits are intended for pediatric and adult patients in professional healthcare environments as a conduit of breathing gas between a patient and a ventilator, and to maintain the temperature of humidified inspired gas.

#### Principle of Operation

The basic principle of operation of the Hudson RCI Dri-Tech Breathing circuit is the inspiratory limb attaches to the Hudson RCI Neptune Heated Humidifier (which is attached to the ventilator inhalation port) and the expiratory limb attaches to the ventilator. The circuit acts as a conduit to ventilate the patient, and maintains the heat and humidity through the use of heated wire within the circuit.
