The design of the hook 15 at the top of the multi-chamber bag 1 enables the multi-chamber bag to be conveniently hung on an infusion stand, saving space. A plurality of sealing strips 2 are arranged in the multi-chamber bag 1. The sealing strip 2 is composed of a concave seat 21 and a convex strip 22. The concave seat 21 and the convex strip 22 are snap-connected. The concave seat 21 and the convex strip 22 are respectively connected to the opposite inner walls of the multi-chamber bag 1. The plurality of sealing strips 2 divide the upper cavity 11, the middle cavity 12 and the lower cavity 13. An upper medicine inlet 111 is provided on the opposite cavity wall of the upper cavity 11, a middle medicine inlet 121 is provided on the opposite cavity wall of the middle cavity 12, and a lower medicine inlet 131 is provided on the opposite cavity wall of the lower cavity 13. Knobs for controlling switches are provided on the upper medicine inlet 111, the middle medicine inlet 121 and the lower medicine inlet 131. The cover plate arranged in the recess of the infusion set effectively protects the infusion set components and prevents the intrusion of dust and bacteria. An infusion set recess 14 is provided at the bottom of the multi-chamber bag 1. A cover plate is arranged in the infusion set recess 14, and an infusion set component is arranged in the infusion set recess 14. The infusion set component includes an infusion tube 31.
