The bubble detector 2 is used to detect whether there is a bubble in the pipeline, and the pipeline closer 3 is used to close the pipeline when the bubble detector 2 detects a bubble. Thus, air can be prevented from entering the patient's body along the pipeline. The bubble detector 2 is an ultrasonic bubble detector.

[0038] Specifically, the pipeline closer 3 comprises a shell 4, which is internally provided with a placing cavity 5 and a movable cavity 6, and is further provided with a guide cavity 7 vertically.
