[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Referring to Figures 1-5 A solvent bag structure, comprising a bag body 1, an infusion port 3 is communicated at both ends of the bag body 1, the infusion port 3 is built-in with a rubber plug 31 for closing the liquid outlet, the end face of the rubber plug 31 is provided with a guide hole 32, the guide hole 32 is used to guide the insertion of a syringe;

[0024] The periphery of the infusion port 3 is further provided with a leakage-proof member 5 through a connecting structure 4, the leakage-proof member 5 is used to shield the rubber plug 31, and the leakage-proof member 5 further blocks the guide hole 32 through a cylindrical member 2, to prevent the drug solution from leaking out through the puncture hole;

[0025] A fixing member 6 is further provided at the infusion port 3, and the bag body 1 is hung on the fixing member 6 through the infusion port 3.

[0026] It should be added that one of the infusion ports 3 is a medicine adding port for a machine, and the other is used to connect a syringe. Because the rubber plug 31 is repeatedly punctured by the syringe during the medicine dispensing process, the elasticity of the rubber plug 31 near the puncture hole is reduced, and the drug solution is easy to leak out through the puncture hole. The leakage-proof member 5 shields the rubber plug 31, and at the same time, can also avoid the leakage of the bag body 1 during transportation;

[0027] The fixing member 6 is connected with a medicine dispensing device or a medicine bag fixing frame, and is used to support the bag body 1.

[0028] Further, the connecting structure 4 comprises a ring-shaped part 41, the bottom of the infusion port 3 is in a continuous step-like structure, and the top is embedded with the rubber plug 31, the ring-shaped part 41 is sleeved on the outer periphery of the bottom of the infusion port 3 and abuts against the infusion port 3 and the bag body 1, and the outer periphery of the ring-shaped part 41 is fixedly connected with the leakage-proof part 5 through a connecting piece 42.

[0036] Finally, the bottom diameter of the infusion port 3 is 60mm, the middle and top diameters are 80mm and 120mm respectively, the bottom of the infusion port 3 is arranged in the center through hole through the accommodation slot 61, and the middle of the infusion port 3 is in contact with the fixing member 6.

[0037] Specifically, the opening diameter of the fixing member 6 is 63mm, the infusion port 3 is put into the hanging ring from the position of the center through hole and naturally falls to the position with a middle diameter of 80mm, and the solvent bag cannot be taken out.

[0038] Working mode; when the solvent bag is used, the leakage prevention member 5 is pulled out from the opening slot 34, the leakage prevention member 5 drives the cylindrical member 2 to separate from the guide hole 32, the syringe is inserted into the rubber plug 31 through the guide hole 32 to dispense or extract the liquid medicine;

[0039] When the dispensing is completed or stopped, the leakage prevention member 5 is inserted and fixed again because the leakage prevention member 5 is connected with the infusion port 3 through the connecting structure 4, the rubber plug 31 can be shielded, the cylindrical member 2 is inserted into the guide hole 32 to plug the opening caused by the puncture, and the liquid medicine is prevented from leaking;

[0040] Finally, the opening diameter of the fixing member 6 is 63mm, the infusion port 3 is put into the hanging ring from the position of the center through hole and naturally falls to the position with a middle diameter of 80mm, and the solvent bag cannot be taken out, and the dispensing or connection of the syringe can be performed.
