The device effectively limits suspension of the tracheal tube and increases storage capacity. When we use the device cooperated >； with monitoring of multi-source end-tidal carbon dioxide, the collected data can be analysed by a carbon dioxide detector and then transmitted to a D/A converter by a frequency controller and displayed on a display screen. During the process of monitoring the multi-source end-tidal carbon dioxide of a patient prepared for intubation with the tracheal tube containing sensor head, the device can visually display the internal situation of the patient with strong visual effects and make it easy to observe. The device can improve the auxiliary effect and ensure the accuracy and stability of intubation. Meanwhile the device can cooperate with wireless sensors for external transmission of data, which facilitates data exchange.1/3 400 ____ ___ ____ ___200 1000 120 - _ .300 ____ ____ ___ ____ __ _ ___230 _____ _____220 130 1 Fig.1I 400 Fig.20
