[0028] The lower end connecting tube of the infusion bag 1 is provided with an anti-bubble drip bucket 9, the lower end of the anti-bubble drip bucket 9 is provided with a connecting hose 10, the outer side of the connecting hose 10 is provided with a switch 11, the upper end of the connecting hose 10 is provided with a precision filter 12, the upper end of the precision filter 12 is provided with an infusion needle 13, the outer side of the infusion needle 13 is slidably sleeved with a protective cover 14, and the surface of the precision filter 12 is provided with a card hole 15.

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The end surface of each sealing sheet 7 is bonded with an elastic member 8, and the other end of the elastic member 8 is bonded to the sealing cover 5. Through the setting of the elastic member 8, the sealing sheet 7 can be tightened. The sealing sheet 7 is in an arc shape as a whole. The sealing sheet 7 is made of elastic rubber material. Through the setting of the sealing sheet 7, the injection tube 4 can be sealed, and the elastic rubber material has good extrusion sealing performance. The sealing cover 5 is in a cylindrical shape as a whole. The sealing cover 5 is made of hard PVC material. Through the setting of the sealing cover 5, the injection tube 4 can be sealed and protected, and the hard PVC material has good durability and protection.

[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 There are two clamping holes 15, which are symmetrically distributed on the precision filter 12. The setting of the clamping holes 15 facilitates the subsequent clamping with the elastic clamping ball 16. The elastic clamping ball 16 is bonded to the inside of the protective cover 14, and the elastic clamping ball 16 is slidably connected to the clamping hole 15.

After the medicine is added to the infusion bag 1, the sealing cover 5 can be pushed to be connected to the outer side of the injection tube 4. During this process, the sealing sheet 7 moves under the pressure of the end of the injection tube 4 to push the elastic member 8 to deform, and finally the sealing sheet 7 contacts the surface of the injection tube 4. Under the action of force, the sealing sheet 7 can slide along the surface of the injection tube 4. When the sealing sheet 7 slides into the sealing ring groove 6, the elastic member 8 restores its deformation to push the sealing sheet 7 into the sealing ring groove 6 to seal the injection tube 4.

[0032] Through the locking action of the locking hole 15 and the elastic locking ball 16, the protective cover 14 can be placed stably, and the infusion needle 13 can be protected to avoid accidental damage to the infusion needle 13. By pulling the protective cover 14 upward to drive the elastic locking ball 16 to move, the elastic locking ball 16 is finally separated from the locking hole 15, and the protective cover 14 is quickly removed, so that the infusion needle 13 is exposed, which is convenient for subsequent infusion use.
