AIRWAY ADAPTOR AND RESPIRATION GAS DETECTION SENSOR

摘要

PROBLEM TO BE SOLVED: To provide an airway adaptor to which a respiration gas detection sensor can be detachably attached with a force as small as possible.SOLUTION: An airway adaptor 10 includes an airway casing 11, a fitting part 21 and a projection 24. The airway casing 11 includes a passage 12 formed therein allowing respiration gas of a living body to pass through. The fitting part 21 is formed in the airway casing 11 and can be detachably fitted to a sensor. The projection 24 is disposed in the fitting part 21 and includes a contact part 24a and a noncontact part 24b. When the airway adaptor 10 is mounted on the sensor, the contact part 24a is brought into contact with the sensor while the noncontact part 24b faces the sensor as spaced from the sensor.
