Further, the containing ring is made of elastic materials.

The tracheal cannula with the body temperature monitoring function has the following advantages:

1, side opening and temperature sensor set up on the cover bag outer wall, when the cover bag inflation, temperature sensor hugs closely inside the human trachea along with the inflation of cover bag, with human organ in close contact, the data of survey is more accurate.

2, soft silica gel rings are arranged at the tail ends of the intubation tubes, so that when the tracheal intubation materials are hard, the insertion ends of the intubation tubes can stab the oral cavity, throat and trachea of a patient.

And 3, sleeving the containing ring 6 between two limiting blocks of the tracheal intubation, and clamping the gas tube and the lead wires of the temperature sensor in the clamping holes of the containing ring, thereby being beneficial to the arrangement and the containing of the joint and the pipeline.
