<P>PROBLEM TO BE SOLVED: To provide an airway adaptor configured to facilitate the attaching/detaching operation of a carbon dioxide gas measuring nasal mask or face mask and an exhaled air guide part and an airway case which is formed to project to the outside of the mask, and configured to be airtight to ensure introduction and ejection of exhaled air passing through the inside of the airway case, inside the mask without leaking to the outside of the mask and further configured to facilitate the attaching/detaching operation of a carbon dioxide gas measuring sensor to/from the airway case. <P>SOLUTION: The airway adaptor includes the airway case 10, and an exhaled air guide part 20 communicatedly connected with the airway case to guide and introduce the exhaled air to the airway case. The airway case is formed with a first exhaled air passage (24) and a second exhaled air passage (26), and the flows of exhaled air flowing in the first exhaled air passage and the second exhaled air passage are set in reverse directions. <P>COPYRIGHT: (C)2011,JPO&INPIT |
