[0040] Working principle: When used, Figure 1 As shown, the insertion end of the catheter body 1 is inserted into the throat of the human body. Because the end is a silicone ring, it is relatively soft and not easy to poke the mouth, throat, and trachea. The connection port 4 is connected, and the air bag 2 is inflated. When measuring the temperature, Figure 6 and Figure 7 As shown, the movable rod 652 is pressed to make the movable rod 652 descend along the first movable groove 651, and the second tooth 656 on the inner wall of the second movable groove 654 is separated from the gap of the first tooth 655, and at the same time, the first spring 653 is squeezed to deform, so that the rotating shaft 63 can rotate, and the rotating knob 64 drives the rotating shaft 63 to rotate, and the adjusting rope 56 is pulled to wrap around the surface of the rotating shaft 63, as shown in FIG. Figure 5 As shown, the adjusting rope 56 is pulled to move along the first sliding hole 57, and is connected to the connecting tube 53 and the adjusting rope 56 through the ring 55, so that the connecting tube 53 is bent outward, and the bending angle of the connecting tube 53 is adjusted, and the body temperature detection probe 54 is closely attached to the inside of the human trachea and in close contact with the human organs to measure the temperature. After adjustment, as shown in FIG. Figure 7 As shown, the movable rod 652 is loosened, and under the rebound action of the first spring 653, the second tooth 656 on the inner wall of the second movable groove 654 is inserted into the gap of the first tooth 655 to lock the rotating shaft 63 to prevent it from rotating. After use, Figure 5 and Figure 6 As shown, the locking of the rotating shaft 63 is canceled, and the knob 64 is rotated. Under the action of the connecting tube 53 and the second spring 7, the connecting tube 53 is bent and then automatically restored. The above is the entire working principle of the present invention.
