A plurality of small humidity sensors 6 are distributed inside the detection ring 5, and the plurality of small humidity sensors 6 are evenly distributed on the outside between the pipe body 4 and the connecting seat. The sensing ends of the humidity sensors 6 are exposed outside so as to quickly sense the change of the humidity around the pipeline. When the pipeline leaks, the leaked liquid rapidly increases the humidity of the surrounding environment. The humidity sensors 6 convert the humidity change into an electrical signal change. When the electrical signal detects the humidity, it triggers the alarm 8 to emit a loud alarm sound to intuitively prompt the medical staff that the pipeline leaks. When the pipe body 4 operates normally, move the protective outer frame 18 to surround the outside of the pipe body 4 by moving the slider 25 inside the chute 19, and insert the second insertion block 28 into the inside of the bottom groove 24 to fix the position of the protective outer frame 18 after movement. When an external device comes into contact with it, it will directly contact the protective outer frame 18 to avoid direct contact with the pipe body 4, improving the protection performance. After long-term use, remove the fastening ring 22 to separate the fastening ring from the insertion rod 31, then pull out the insertion rod 31 to separate the insertion rod 31 from the insertion hole 29, and pull out the protective outer frame 18 to separate the extension plate 27 from between the two clamping plates 30, so that the protective outer frame 18 can be separately disassembled for maintenance or replacement, improving the flexibility during use.

The problem solved by the present invention is that in the actual use of existing hemodialysis machines, the pipeline system of the hemodialysis machine plays a crucial role. It is responsible for transporting blood and dialysate. However, due to reasons such as long-term use of the pipeline, loose connection parts, or aging of the pipeline, liquid leakage may occur. Liquid leakage not only causes waste of dialysate and blood, but also may expose patients to the risk of infection and endanger their lives due to blood loss. Some traditional liquid leakage detection devices have problems such as low detection accuracy, slow response speed, or complex structure and inconvenient installation. Therefore, a pipeline liquid leakage detection device for hemodialysis machines is needed to overcome these deficiencies. Through the mutual combination of the above components, the device is equipped with a detection ring and a humidity sensor outside the tube body, which can quickly sense the humidity change caused by liquid leakage and trigger an alarm through an electrical signal to notify medical staff in a timely manner.
