    摘要: An airway adaptor that measures the concentration of at least one of a specific component and the flow rate of a supply gas and a return gas. The airway adapter may include a tube having a flow path in which the supply gas and the return gas passes. The tube may include a first end having a first aperture for guiding the supply gas into the flow path, and second end having a second aperture for guiding the return gas. Further, the airway adapter may include a measurement device operable to measure at least one of the supply gas and the return gas in the air flow path and a partial shielding disposed at the first aperture and structured to shield a portion of the air flow path. The supply gas may be a respiratory gas and the return gas may be inhaled or exhaled breath of a person.

    摘要: Windows 2 which allow infrared light to be transmitted therethrough are opened at opposed positions of side walls of a flow tube 1, respectively. A hexagonal frame 6 is air tightly attached to each of the apertures. Each frame 6 is protruded from the inner face of the flow tube 1. A transparent window on which an anti-fogging layer 5 is formed stretches on the inner face of each of the frame 6, so that waterdrops flowing through the flow tube 1 are caused to flow along both the sides of the frame 6, thereby preventing the waterdrops from flowing over the anti-fogging layer 5.
