[0023] See also Figure 1 Two elastic bands 14 are installed on the outer surface of the protective shell 1. The two elastic bands 14 are elastic. A card slot 3 is opened on one side of the outer surface of the protective shell 1, and a transparent plate 4 is installed on one side of the outer surface of the card slot 3.

[0024] The blood bag body 2 can be clamped by two elastic bands 14 to prevent it from falling. Through the arrangement of the drawer slot 3, the information note of the blood bag can be put in, and through the transparent plate 4, it can be convenient to observe it.

[0025] See also Figure 2 The blood bag body 2 is placed inside the protective shell 1, and a lifting portion 21 is provided on the top of the blood bag body 2. A puncture tube 22 is provided at the bottom of the blood bag body 2, and the puncture tube 22 is inserted into the through hole 6.

[0026] By providing the lifting portion 21 , after the protective shell 1 and the elastic band 14 fix the blood bag body 2 , the blood bag and the protective shell 1 can be hung by the lifting portion 21 .

[0027] See also Figure 4 A fixing ring 10 is installed at the bottom of the protective shell 1, and a connecting tube 11 is installed inside the fixing ring 10. One end of the connecting tube 11 passes through the protective groove 7 and contacts the puncture tube 22.
