Bioreactor bags are widely used, especially in the production of biological products. They provide a convenient, efficient and environmentally friendly way to culture cells and conduct biological reactions. In addition, bioreactor bags also play an important role in scientific research and clinical trials.

[0003] However, in existing equipment, most bioreactor bags require staff to manually close the feed tube. Due to the staff's slow reaction speed, some air will enter the reaction bag when closing the feed tube. The air contains bacteria, which is not conducive to the biological reaction in the reaction bag. Therefore, a self-locking bioreactor bag is proposed. Utility Model Content

[0018] The utility model has the following beneficial effects:

[0019] 1. Compared with the prior art, the self-locking bioreactor bag is provided with a sliding rod, a movable plate, a conical plug, and a spring, and is connected to an external feed pipe through an anti-detachment connecting tube. Then, an external feed pump delivers the biological liquid through the feed pipe into the anti-detachment connecting tube, and then through the anti-detachment connecting tube into the filter tube. The biological liquid then squeezes the conical plug. The conical plug pushes the movable plate to slide on the two sliding rods and squeezes the spring, causing the conical plug to disengage from the conical hole. The liquid flows into the feed pipe through the gap between the conical plug and the conical hole, and then flows into the transparent reaction bag. When the external liquid delivery stops and the pressure of the biological liquid in the filter tube decreases, the elasticity of the spring causes the spring to push the movable plate on the two sliding rods. The movable plate drives the conical plug to quickly plug into the conical hole, blocking the conical hole in time, preventing a large amount of air from entering the transparent reaction bag, causing bacteria in the air to affect the biological reaction in the transparent reaction bag.

[0020] 2. Compared with the existing technology, the self-locking bioreactor bag is provided with a first sphere, a rotating column and a first handle. When the first handle is rotated, the first handle drives the rotating column to rotate, and the rotating column drives the first sphere to rotate, so that the first sphere blocks the feed tube, and then the filter tube is rotated and taken out through the fixed tube, thereby preventing air from entering the transparent reaction bag from the feed tube, making it convenient for staff to replace damaged self-locking structures.

[0031] 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.

[0032] Reference Figures 1 to 8 The bottle cap 12 is fixedly connected to the bottom of the bottle cap 12, and a rotating handle 14 is rotatably connected to one side of the bottle cap 12. One end of the rotating handle 14 is fixedly connected to the second sphere 13, and a second feeding hole is provided on one side of the second sphere 13. The second sphere 13 is rotatably connected to the inside of the bottle cap 12. The upper surface of the transparent reaction bag 1 is fixedly connected to the two handles 2. The upper surface of the transparent reaction bag 1 is fixedly connected to the feeding pipe 3. The upper surface of the feeding pipe 3 is provided with a threaded hole, and the threaded hole is threadedly connected to the fixing pipe. The upper surface of the fixing pipe is fixedly connected to the filter tube 4. The filter plate 10 is fixedly connected to the inside of the filter tube 4 to filter the liquid medicine to prevent liquid medicine residue from entering the transparent reaction bag 1 and affecting the liquid medicine reaction. The filter tube 4 is fixedly connected to a fixing disk 11, and the bottom of the fixing disk 11 is provided with a conical groove. The filter tube 4 is provided with a self-locking structure 6. The upper surface of the filter tube 4 is fixedly connected to an anti-detachment connecting tube 5.

[0033] In order to achieve the purpose of replacing the self-locking structure 6, the inside of the feeding tube 3 is rotatably connected to the first sphere 7, and a first feeding hole is opened on one side of the first sphere 7. A rotating column 8 is fixedly connected to one side of the first sphere 7. One end of the rotating column 8 passes through and is rotatably connected to one side of the feeding tube 3 and is fixedly connected to a first handle 9. When the first handle 9 is rotated, the first handle 9 drives the rotating column 8 to rotate, and the rotating column 8 drives the first sphere 7 to rotate, so that the first sphere 7 blocks the feeding tube 3, and then the filter tube 4 is rotated and the filter tube 4 is taken out through the fixed tube to prevent air from entering the transparent reaction bag 1 from the feeding tube 3, making it convenient for the staff to replace the damaged self-locking structure 6;

[0034] In order to prevent a large amount of air from entering the transparent reaction bag 1, the self-locking structure 6 includes two sliding rods 601 fixedly connected to the bottom of the filter tube 4, the other ends of the two sliding rods 601 are fixedly connected to the bottom of the fixed disk 11, and a movable plate 602 is slidably connected to the two sliding rods 601. The bottom of the movable plate 602 is fixedly connected with a spring 604, and the other end of the spring 604 is fixedly connected to the inner bottom of the filter tube 4. The upper surface of the movable plate 602 is fixedly connected to the conical plug 603, and the conical plug 603 is adapted to the conical groove. A sealing gasket is fixedly connected to one side of the conical plug 603 that fits the conical groove. It is connected to the external feed pipe through the anti-detachment connecting pipe 5, and then the external feed pump transports the biological liquid into the anti-detachment connecting pipe 5 through the feed pipe. Then, the liquid is transported into the filter tube 4 through the anti-detachment connecting tube 5, and then the conical plug 603 is squeezed by the biological liquid. The conical plug 603 pushes the movable plate 602 to slide on the two sliding rods 601 and squeezes the spring 604, so that the conical plug 603 is separated from the conical hole, and the liquid flows into the feeding tube 3 from the gap between the conical plug 603 and the conical hole, and then flows into the transparent reaction bag 1. When the external liquid delivery stops and the pressure of the biological liquid in the filter tube 4 decreases, the elasticity of the spring 604 causes the spring 604 to push the movable plate 602 to move on the two sliding rods 601, and the movable plate 602 drives the conical plug 603 to quickly plug into the conical hole, blocking the conical hole in time, and preventing a large amount of air from entering the transparent reaction bag 1, causing bacteria in the air to affect the biological reaction in the transparent reaction bag 1;

[0035] In order to achieve the purpose of stirring, the bottom of the transparent reaction bag 1 is fixedly connected to a fixed plate 15, the upper surface of the fixed plate 15 is rotatably connected to a rotating rod 16, and a plurality of stirring fans 17 are fixedly connected to the rotating rod 16. The bottom of the fixed plate 15 is fixedly connected to a rotating motor 18, and the output shaft of the rotating motor 18 is fixedly connected to the bottom of the rotating rod 16. The rotating motor 18 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the plurality of stirring fans 17 to rotate. The plurality of stirring fans 17 stir the biological liquid, which is conducive to uniform mixing reaction of the liquid.

[0036] Working principle: The anti-detachment connecting tube 5 is connected to the external feeding tube, and then the external feeding pump transports the biological liquid through the feeding tube into the anti-detachment connecting tube 5, and then transports it into the filter tube 4 through the anti-detachment connecting tube 5, and then squeezes the conical plug 603 through the biological liquid. The conical plug 603 pushes the movable plate 602 to slide on the two sliding rods 601 and squeezes the spring 604, and the conical plug 603 is separated from the conical hole. The liquid flows into the feeding tube 3 from the gap between the conical plug 603 and the conical hole, and then flows into the transparent reaction bag 1. When the external liquid delivery stops and the pressure of the biological liquid in the filter tube 4 decreases, the spring 604 is pressed. The elasticity causes the spring 604 to push the movable plate 602 to move on the two sliding rods 601. The movable plate 602 drives the conical plug 603 to quickly plug into the conical hole, blocking the conical hole in time to prevent a large amount of air from entering the transparent reaction bag 1, causing bacteria in the air to affect the biological reaction in the transparent reaction bag 1. The first handle 9 is rotated, and the first handle 9 drives the rotating column 8 to rotate. The rotating column 8 drives the first sphere 7 to rotate, so that the first sphere 7 blocks the feeding tube 3, and then the filter tube 4 is rotated and the filter tube 4 is taken out through the fixed tube to prevent air from entering the transparent reaction bag 1 from the feeding tube 3, making it convenient for the staff to replace the damaged self-locking structure 6.
