Technical Field
[0001] The utility model relates to the field of reaction bag mixing, in particular to a disposable reaction bag capable of axial movement and diversion mixing. Background Art
[0002] A disposable reaction bag is a disposable consumable that provides space for reactants such as cells and microorganisms, as well as the culture fluid they need. During the reaction process, it is often necessary to add culture fluid and other substances, and at this time the contents need to be mixed. At the same time, in order to homogenize the culture process, the reactants also need to be mixed. Whether it is mixing or blending, the contents in the bag need to flow. But it is worth noting that the environment provided by the disposable reaction bag needs to be sterile and airtight. In the prior art, common methods include rocking and paddle types. The rocking type is to place the disposable reaction bag on a shaker, and through the shaking of the shaker, the contents have wave-like fluctuations to achieve the effect of mixing. The paddle type commonly used is a magnetically coupled paddle, which is achieved by arranging magnets circumferentially around the paddle and driving the paddle to rotate with an electromagnetic drive magnet across the bag body.

[0030] like Figure 1-4As shown, a disposable reaction bag with axial motion-directed mixing includes a bag body 1 and a mixing device provided at the bottom of the bag body 1. The mixing device includes a mixing disc 2, an inner and outer connecting rod 11, a motor 7, and a flexible funnel 4. The mixing disc 2 is provided inside the bag body 1, and the flexible funnel 4 is provided at the bottom of the bag body 1. One end of the inner and outer connecting rod 11 is connected to the mixing disc 2, and the other end passes through the flexible funnel 4, and the end is connected to the motor 7. The device sets the mixing disc 2 in the bag body 1, and controls the axial movement of the inner and outer connecting rod 11 by the motor 7, controls the displacement of the mixing disc 2 in the bag body 1, and performs a mixing operation on the liquid medicine in the bag body 1. The device is easy to operate and has a good mixing effect. The device stirs in an axial motion manner, which can reduce the shearing of the liquid medicine while improving the mixing efficiency of cell culture, and reduce the shearing of cells during the mixing process.
[0031] The mixing disc 2 is integrally injection-molded with the inner and outer connecting rods 11 and connected to one end of the inner and outer connecting rods 11, forming a T-shape. The mixing disc 2 is provided with multiple water holes 3. These holes 3 include an upper reamer hole 8, a middle oblique hole 9, and a lower reamer hole 10. The diameters of the upper and lower reamer holes 8 and 10 are larger than those of the middle oblique hole 9. The edge of the middle oblique hole 9 extends in a direction that intersects with the upper and lower reamer holes 8 and 10, and the middle oblique hole 9 is an oblique hole.
[0032] The flexible funnel 4 is a flexible part in the shape of a funnel. The weld edge 13 at the top is connected to the bottom opening of the bag body 1 and is welded to the inner wall of the bag body 1. The lower end of the flexible funnel 4 is opened, and multiple annular sealing protrusions 12 are set on the inner side of the end. The bottom end of the flexible funnel 4 is sleeved on the inner and outer connecting rods 11. The corresponding positions of the depressions and protrusions are held from the outside by the clamp 5, and the flexible funnel 4 is fixed to the inner and outer connecting rods 11 so that the bag can be sealed. The mixing disk 2 is connected to the inner and outer connecting rods 11, which makes it easy to control the mixing disk 2 to move and stir the liquid medicine in the bag body 1 through the inner and outer connecting rods 11, and the mixing disk 2 is provided with a water hole 3. The liquid medicine flows smoothly through the water hole 3, and the mixing efficiency is higher and the mixing is more thorough.
[0033] The connection between the bottom ends of the inner and outer connecting rods 11 and the flexible funnel 4 is provided with multiple sealing recesses 15, which mate with the sealing protrusions 12. A bolt slot 14 is provided at the bottom end of the inner and outer connecting rods 11, which connects to the end of the motor connecting rod 6 on the motor 7. The flexible funnel 4 connects the bag body 1 and the inner and outer connecting rods 11, forming a funnel shape. As the inner and outer connecting rods 11 reciprocate up and down, it can accommodate the deformation and wrinkles caused by the upward and downward compression of the flexible funnel 4.
[0034] When the device is in use, the motor 7 drives the motor connecting rod 6 to reciprocate up and down, which in turn drives the inner and outer connecting rods 11 to reciprocate up and down. The mixing disc 2, connected to the inner and outer connecting rods 11, also moves together, with the amplitude of the movement adjusted according to the height of the contents. When the mixing disc 2 rises, the medicinal liquid passes through the upper reamer 8 of the water hole 3, and after passing through the middle oblique hole 9, the vertical downward movement of the medicinal liquid is changed to an oblique downward flow. The lower reamer 10 does not block the flow of the medicinal liquid. Similarly, when the mixing disc 2 descends, the medicinal liquid passes through the lower reamer 10 of the water hole 3, and after passing through the middle oblique hole 9, the vertical upward movement of the medicinal liquid is changed to an oblique upward flow. The upper reamer 8 does not block the flow of the medicinal liquid. The up and down displacement of the mixing disc 2 mixes the medicinal liquid, achieving a good mixing effect and high efficiency.
[0035] The embodiments described above are merely descriptions of preferred implementation methods of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by technical personnel in this field to the technical solution of the present invention should be included in the scope of protection determined by the claims of the present invention.
