The invention relates to the technical field of terminal sterilization and filtration in a radiopharmaceutical preparation process, in particular to a filter membrane sterilization and filtration device and system. Comprising the steps that a state sensing module collects liquid medicine radioactive activity data and filter membrane structure strain data and generates real-time data flow; the twinborn modeling module constructs a filter membrane digital twinborn body, and outputs an accumulated radiation damage prediction result through data assimilation; the prediction decision module generates a filtering parameter optimization sequence by using a deep reinforcement learning agent; the control execution module adjusts the flow velocity of the liquid medicine through fuzzy self-adaptive PID control and feed-forward compensation; and the verification feedback module performs an integrity test and transmits data back to the twin modeling module to realize model parameter correction. All the modules form a closed-loop control system through a high-speed data bus, so that the damage of radiation to a filter membrane material is effectively inhibited, and the integrity and the sterile guarantee level of a membrane structure in the filtering process are maintained.

The invention provides an electron beam sterilization method of an implant, which is characterized in that the implant is irradiated by using a high-energy electron beam, the irradiation mode is at least twice, the irradiation dose of each time is not more than 20kGy, and the absorbed dose of the implant after irradiation is not less than 16kGy and not more than 50kGy. The method provided by the invention can ensure that the sterility level SAL is less than 10 <-6 >, can ensure that the drug quality of the implant is not affected, and can ensure that no new impurities are generated in the sterilization process.

The invention provides a sterilization method for a product containing a marine organism extract, which adopts a moist heat sterilization process, the moist heat sterilization process is carried out by adopting a staged pressure pulse synergistic mode, the sterilization temperature is 120-130 DEG C, and the sterilization time is 9-15 minutes; the product contains sodium alginate, trehalose and other raw materials, an intermediate is prepared through a specific preparation technology, and the intermediate is filled, sealed and sterilized. A bacillus stearothermophilus biological indicator verifies that the sterility guarantee level of a sterilized product is less than or equal to 10 <-6 >, indexes such as pH and heavy metals meet standards, and sodium alginate is stable and is not obviously degraded; the method disclosed by the invention avoids the problems of pungent smell and component degradation of irradiation sterilization, improves the production efficiency and reduces the energy consumption compared with the traditional moist heat sterilization, gives consideration to the sterile effect and the product performance stability, and is suitable for skin care products containing marine organism extracts.

The invention belongs to the field of pharmaceutical preparations, and particularly relates to a diphenhydramine hydrochloride composition and a preparation method thereof. According to the diphenhydramine hydrochloride injection disclosed by the invention, the pH of the diphenhydramine hydrochloride solution is adjusted by adopting carbon dioxide, and terminal sterilization is performed on the diphenhydramine hydrochloride solution, so that the sterile guarantee level of the diphenhydramine hydrochloride injection is improved, and the clinical use safety is greatly improved.

The invention relates to the field of medical beauty materials, in particular to injectable cross-linked recombinant collagen gel for medical beauty and a preparation method of the injectable cross-linked recombinant collagen gel. Mixing the recombinant collagen with glutamine transaminase, and carrying out cross-linking reaction to form gel; carrying out dialysis on gel formed by crosslinking in normal saline at the temperature of 2-8 DEG C for 12-24 hours so as to remove free glutamine transaminase; diluting the dialyzed gel to a target concentration; and filling the diluted gel, and carrying out terminal moist heat sterilization under the conditions that the temperature is 121 DEG C and the standard sterilization time is greater than or equal to 12 minutes, so that the gel is homogenized. According to the technical scheme, through specific crosslinking and subsequent process treatment, the obtained gel can tolerate terminal moist heat sterilization conditions that the temperature is 121 DEG C and the F0 is greater than or equal to 12 minutes. Therefore, an expensive and high-risk sterile filling process can be abandoned in production, but a terminal sterilization process with more consistent batch sterility guarantee level is adopted, so that the production cost and the quality risk are remarkably reduced.
