[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 3 As shown, an infusion set with multi-level adjustable drip volume includes an infusion tube 1. An adjuster 2 is fitted around the outside of the infusion tube 1. The adjuster 2 includes a fixing member 3 and an adjusting sleeve 4. The infusion tube 1 passes through both the fixing member 3 and the adjusting sleeve 4. The adjusting sleeve 4 is movable, allowing the fixing member 3 to clamp and compress the infusion tube 1. Specifically, the fixing member 3 has a boss 31 at its lower part, and the adjusting sleeve 4 is fitted around the boss 31. The adjusting sleeve 4 has a threaded portion 41 on its inner side, which is threadedly connected to the boss 31. The adjusting sleeve 4 can rotate upwards or downwards. Multiple clamping pieces 32 are provided at the lower part of the boss 31. The infusion tube 1 passes through the area enclosed by the multiple clamping pieces 32. The adjusting sleeve 4 can abut against and compress the clamping pieces 32, causing them to deform and compress the infusion tube 1. A clamping sleeve 42 is provided inside the adjusting sleeve 4. The clamping sleeve 42 includes a conical sleeve 421, with the lower end of the clamping pieces 32 located inside the conical sleeve 421.
