[0003] The main body of the infusion tube is an infusion hose, which connects the needle and the liquid medicine container and transports the liquid medicine into the patient's body. According to different materials, the infusion hose can be divided into various types such as silicone rubber tubes, PVC tubes, TPU tubes, polyamide tubes, polyurethane tubes, and steel wire reinforced tubes. Each material has its unique performance and application scenarios.

[0004] Due to its soft structure, when performing airtightness detection on the infusion tube, generally, samples are randomly inspected, and then manually loaded onto the detection device for airtightness detection.
