Description
Technical Field
The utility model relates to the field of biotechnology, in particular to cell filter bag.
Background
The stem cell technology has become the breakthrough for overcoming various difficult and complicated diseases for human in this century, and is first judged as a ten-year-old scientific achievement by the American journal for science in two years. Currently, stem cells widely used in clinics include: cord blood stem cells, mesenchymal stem cells, neural stem cells, and the like. The stem cells are not only used for clinical treatment of various blood system diseases, immune system diseases and nervous system diseases, but also are beginning to be widely applied to regenerative medicine, including clinical treatment of various diseases such as tumors, heart diseases, ophthalmic diseases, diabetes, orthopedic surgery, brain and spinal cord injuries and the like. In the clinical application process of the mesenchymal stem cells, the mesenchymal stem cells are required to be prepared into an injection capable of being infused, and the whole preparation process requires sterile operation.
The existing filtering device is characterized in that a filtering membrane is placed when a liquid discharge pipe is movably inserted into a liquid inlet of an injection bag, and the filtering membrane and the liquid inlet are in contact with the external environment, so that the risk of bacterial pollution is caused, and the installation of the filtering membrane is a complicated process.
Disclosure of Invention
To the problem that exists among the background art, the utility model provides a cell filter bag, its manual connection installation of filtration membrane and each subassembly when having reduced the filtration facilitates the use, raises the efficiency. Meanwhile, parts such as a filtering membrane and the like are prevented from contacting with the external environment in the operation process, the safety of cells is ensured, and the risk of bacterial pollution is reduced.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the cell filter bag comprises: the injection bag I, the liquid discharge pipe, the filter and the injection bag II; the liquid outlet I on the injection bag I and the inlet II on the injection bag II are connected through a liquid discharge pipe, a hemostatic valve is arranged on the liquid discharge pipe at the I position of the liquid outlet of the injection bag I, a filter is arranged on the liquid discharge pipe and consists of a cylindrical pipe and a filtering membrane, and the filtering membrane is fixedly arranged in the cylindrical pipe.
Preferably, the diameter of the cylindrical pipe is at least 10cm greater than the diameter of the drain pipe.
The utility model has the advantages that:
the utility model provides a cell filter bag, its manual connection installation of filtration membrane and each subassembly when having reduced the filtration facilitates the use, raises the efficiency. Meanwhile, parts such as a filtering membrane and the like are prevented from contacting with the external environment in the operation process, the safety of cells is ensured, and the risk of bacterial pollution is reduced.

Detailed Description
In order to make the objects, technical solutions and technical effects of the present invention clearer, the following will explain in detail the advantageous embodiments of the present invention with reference to the accompanying drawings, so as to facilitate the understanding of the skilled person.
As shown in fig. 1, the cell filter bag comprises: the injection bag I1, the liquid discharge pipe 2, the filter 3 and the injection bag II 4; a liquid outlet I5 on an injection bag I1 and a liquid inlet II 6 on an injection bag II 4 are connected through a liquid discharge pipe 2, injection in the injection bag I1 is squeezed into the injection bag II 4 through the liquid discharge pipe 2, a hemostatic valve 7 is arranged on the liquid discharge pipe 2 at the position of the liquid outlet I5 of the injection bag I1, when the injection is not squeezed, the liquid discharge pipe 2 is clamped through the hemostatic valve 7 to prevent the liquid from automatically flowing out, a filter 3 is arranged on the liquid discharge pipe 2 and consists of a cylindrical pipe 8 and a filter membrane 9, two ends of the cylindrical pipe 8 and the liquid discharge pipe 2 are integrally formed, the filter membrane 9 is fixedly arranged in the cylindrical pipe 8, the aperture of the filter membrane 9 is 0.22 micron, the requirement of 99.99 percent sterilization specified by GMP or pharmacopoeia can be met, the diameter of the cylindrical pipe 8 is at least 10cm larger than the diameter of the liquid discharge pipe 2, and the flow rate of the injection can be slowed down, the filtration is more sufficient, and after the injection is filtered, the liquid discharge pipe 2 on the liquid inlet II 6 of the injection bag II 4 is sealed in a heat sealing way.
The utility model provides a cell filter bag, its manual connection installation of filtration membrane and each subassembly when having reduced the filtration facilitates the use, raises the efficiency. Meanwhile, parts such as a filtering membrane and the like are prevented from contacting with the external environment in the operation process, the safety of cells is ensured, and the risk of bacterial pollution is reduced.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
