Moreover, the two detection bodies are sealed and connected, which can prevent external air from entering the detection cavity 7 and affecting the detection results. During the detection, hydrogen peroxide sterilization gas is input into the catheter, and the sterilization gas sterilizes the bacteria on the contaminated carrier 5 in the detection cavity 7 to achieve the purpose of simulating the detection sterilization effect. The detection part 1 is added at the disconnection position in the middle of the catheter to ensure that the contaminated carrier 5 is located in the middle of the stainless steel tube, thereby ensuring the accuracy of the detection results.

[0030] Furthermore, the first detection body 101 has an assembly cavity 8 inside, and the second detection body 102 is provided with the detection cavity 7. The first detection body 101 and the second detection body 102 are connected by a thread and a sealing ring 4. The catheter is composed of a first air duct 2 and a second air duct 3 of equal length.

The bacterial carrier 5 needs to be kept in a horizontal state. Then the second detection body 102 is assembled, and the second detection body 102 is screwed until the right end of the bacterial carrier 5 is inserted into the left end of the second air guide pipe 3 by the same distance. At this time, the bacterial carrier 5 is mostly exposed and in a suspended state. At this time, sterilization gas can be introduced into the air guide pipe for detection.

[0043] Furthermore, the inner wall of the assembly cavity 8 is provided with an internal thread, and the outer wall of the second detection body 102 is provided with an external thread adapted to the internal thread. One end of the first detection body 101 extends into the assembly of the second detection body 102 and is threadedly connected to the second detection body 102. The end of the second detection body 102 extending into the assembly cavity 8 contacts the side wall of the assembly cavity 8, and a sealing ring 4 is provided between the first detection body 101 and the second detection body 102.
