[0031] The ultrafiltration collector for Ruijianosan injection provided by the utility model works as follows when in use:

[0032] Ensure that the ultrafiltration collection tube 1 is clean and sterile, and check whether all parts are intact, then take the collection tube 1 out of the packaging bag, and then install and fix the end cap 5 at the bottom of the collection tube 1, then take out the ampoule filled with the Rigano crude drug liquid, and according to the dosage of the medicine used, take out the appropriate number of ampoules, then open these ampoules, and then inject the liquid in these ampoules into the collection tube 1 through the liquid inlet port 2 at the top of the collection tube 1, then take out the air bag 7 from the packaging bag, and then install and connect the sealing cover 3 at the lower end of the air bag 7 to the liquid inlet port 2, and ensure that the sealing cover 3 is tightly connected to the liquid inlet port 2 and there is no air leakage.

[0033] When the air bag 7 is installed, the valve 32 outside the top connector 31 of the sealing cover 3 is opened, and then the sterile gas in the air bag 7 enters the collection tube 1 through the hollow tube inside the connector 31. During this process, the operator squeezes the air bag 7, so that the sterile gas in the air bag 7 enters the collection tube 1 and squeezes the upper part of the collection tube 1. Then, the medicine above the collection tube 1 is pressurized and enters the bottom of the collection tube 1 through the filter 4. Then, the medicine passes through the filter 6 above the end cover 5 and enters the guide tube 51. Since the collection tube 1, the guide tube 51 and other structures are transparent, when there is a certain amount of medicine in the guide tube 51, the syringe is taken out, the needle of the syringe is inserted through the silicone sleeve 52 into the guide tube 51, and the medicine in the guide tube 51 is extracted. Through the above process, the Ruijianosan injection ultrafiltration collector can effectively remove impurities and microorganisms in the medicine liquid, protect the quality of the medicine, reduce the risk of cross contamination, and ensure the safety of the patient's medication.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
