Embodiment 1
[0019] Add the prescribed amount of methylene blue and glucose into 50ml of water for injection, fully dissolve, heat to 70°C, then add 0.12g of activated charcoal for needles into the solution, keep stirring for 30 minutes, filter while hot, and use for filtration The pore size of the microporous filter membrane is less than 0.22um. After filtering, the intermediate solution without particles is added to 100ml with finely filtered water for injection, and then set aside. Then add 10ul of the above-mentioned pathogen inactivator intermediate solution dropwise to each clean medicinal polyester film, dry it under a 100-level laminar flow hood, and after passing the inspection of content, sterility, pyrogen, and particles, the The solid blood or blood component pathogen inactivating agent composition used together with a carrier can be applied to a blood pathogen inactivating device. The specific prescription is shown in Table 1:
