Device type (GMDN): Non-heated respiratory humidifier

A device designed to prevent the drying of airway passages associated with the inhalation of oxygen (O2) by adding water vapour to the dry gas as it is passed through, or more seldom, over water. It typically consists of a graduated container (reservoir) for the water, a top piece that functions as a detachable lid (typically a screw lid with a gastight seal), and a tube that protrudes into the water to divert the gas below the water level. This device, commonly known as a bubble humidifier, does not heat the water. It has connectors: 1) one (e.g., a winged nut) that connects to an oxygen therapy flowmeter; and 2) one to which the patient tubing is connected. This is a reusable device.
