Intubation tube has sensor that is fixed to wall of intubation tube to detect carbon dioxide concentration of inhaled air passing through tube and t o output carbon dioxide concentration signal

摘要

The intubation tube (10) has a sensor that detects carbon dioxide concentration of inhaled air passing through the intubation tube and outputs a carbon dioxide concentration signal. The sensor is fixed to a holder arranged on wall of the intubation tube and comprised with a solid electrolyte and a heating device for heating the solid electrolyte. The solid electrolyte contains sodium ions. An independent claim is included for intubation system.
