DEVICE: Carina VPack NIV NovaS Fullf L (04048675421115)

A screening device intended to remove microbes from medical gases to prevent patient exposure during respiration, anaesthesia and/or endoscopy; it has no additional non-filtering functions. It is a small plastic housing containing a filter which will typically also filter other particulates (e.g., scale). This is a single-use device.

A non-sterile, flexible, form-shaped device designed to be placed over the nose and mouth to deliver a proportional mixture of air/oxygen (O2) to a patient's airway. It is made of non-conductive, soft, flexible polymers available in a range of sizes, and designed to create an airtight seal against the patient's face. The device may include tubing and various valves and connectors which may allow for connection to a central vacuum system to enable scavenging of residual (waste) anaesthetic gas from a patient in recovery; other respiratory equipment (e.g., nebulizer, humidifier, CPAP device) is not included. This is a single-use device.

A non-sterile device that is a one-way valve used to direct the flow of breathing gases and prevent the patient rebreathing the exhaled gases. It is typically used in a breathing system or between an oxygen mask and its reservoir bag. The device may be of various designs and will typically include unidirectional valves made of, e.g., silicone, rubber, metal, mica, sheets or discs that open and close for each inspiration/expiration. This is a reusable device.

An assembly of devices designed to conduct air or oxygen (O2) enriched gases and additional gases [e.g., nitrous oxide (N2O), halogenated gases] from a ventilator to a patient artificial airway/respiratory mask (not included). It includes breathing tubes, a Y-piece connector, and provides connections for devices that humidify, deliver medication, and monitor gas concentration or pressure within the breathing circuit; some types may include a carbon dioxide cuvette and/or an integrated heating wire powered by a connected humidifier intended to warm breathing gases as they enter the patient's airway. This is a single-use device.
