The temperature sensor comprises a temperature probe 2 and a temperature probe joint 3.

The front end of the catheter 1 is provided with a balloon 1a. The rear end of the catheter 1 is connected with one end of the first pipeline 4 in a sealing way. The catheter 1 has two completely independent paths; one way is a urinary tract 1b, and the other way is a data way 1c; the data path 1c has a bifurcated opening 1d.

The temperature probe 2 is electrically connected with one end of the data line 2 a; the data line is located in the data path 1c, and after passing out from the bifurcation opening 1d, the other end of the data line is electrically connected to the temperature probe connector 3.

The first path of the three-way valve 6 is connected with the other end of the first pipeline 4 in a sealing way. In this embodiment, the first path of the three-way valve 6 is connected with the other end of the first pipeline 4 in a sealing manner by using a first luer connector 5. The second path of the three-way valve 6 is in sealing connection with one end of a second pipeline 15. In this embodiment, the second channel of the three-way valve 6 is sealingly connected to one end of the second conduit 15 by means of a second luer fitting 7. The third path of the three-way valve 6 can be externally connected with a physiological saline flushing pipeline. The third path is provided with an on-off switch for controlling the opening and closing of the end.
