Intended Use

The ConchaTherm® Neptune® is a respiratory humidifier designed to heat and humidify respiratory gases delivered via endotracheal tubes, nasal cannula or face masks to adult, pediatric, infant and neonatal patients. This system may be used with either conventional (non-heated wire) breathing circuits or compatible (21-volt) Hudson Respiratory Care Incorporated (RCI) heated-wire circuits. The ConchaTherm® NeptuneTM can be used with ventilators, continuous flow systems, oxygen diluters and blenders, adjustable nebulizer adapters for aerosol therapy, or nonflammable anesthesia gases to help maintain patient body temperature. When used with the Hudson RCI ConchaTherm Neptune Heated Humidifier and Hudson RCI ventilator circuits, the ConchaSmart Column provides heated humidification for patients with and without an artificial airway in place. To provide a continuous flow of heated and humidified gas to spontaneously breathing patients.

Device Story

ConchaTherm Neptune is an active heated humidifier providing heat/moisture to medical gases for invasive/non-invasive ventilation. System components include ConchaSmart Column (disposable humidifier cartridge) and Comfort Flo Humidification System (heated wire breathing circuit). Device accepts input from ventilators, flow systems, or blenders; transforms gas via heated cartridge; outputs heated/humidified gas to patient. Used in clinical settings by healthcare providers. Output helps maintain patient body temperature and airway hydration. System features include low water notification, auto-settings for clinician defaults, and compatibility with 21-volt heated-wire circuits. Benefits include improved patient comfort and respiratory gas conditioning.

Clinical Evidence

Bench testing only. Compliance verified against ISO 8185 (respiratory gas humidifiers), IEC 60601-1 (general safety), IEC 60601-1-8 (alarm systems), and IEC 60601-1-4 (programmable electrical medical systems). Biocompatibility testing performed per ISO 10993-3, -5, -6, -10. Sterility validated per ISO 11137-1/2. Shelf life and useful life testing conducted. Software verification and validation performed.

Technological Characteristics

Active heated humidifier; 21-volt heated-wire circuit compatibility. Materials biocompatibility per ISO 10993. Features: low water notification, auto-settings mode, side-mounting capability. Compliant with ISO 8185:2007. Sterilization per ISO 11137. Software-controlled alarm and temperature regulation.

Indications for Use

Indicated for adult, pediatric, infant, and neonatal patients requiring heated and humidified respiratory gases via endotracheal tubes, nasal cannula, or face masks. Used with ventilators, continuous flow systems, oxygen diluters/blenders, or anesthesia gases. Comfort Flo system indicated for spontaneously breathing patients.

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.
