Description
Technical field
The present invention relates to field of medical device, in particular to a kind of LED ultraviolet lamp source is in photochemical method blood inactivation treatment
Application in equipment.
Background technique
With the continuous development of medical technology, treatment of blood transfusion has become the common medical procedure of modern medicine, such as surgery
Operation needs massive transfusion operation etc..However, blood is the culture medium of good bacterium and virus, especially various viral livers
The viruses such as inflammation, AIDS, are widely present in blood, if dealing with improperly, blood will become pathophorous medium.Therefore, lead to
It is even more troubling to cross the disease propagated using blood product.
Ensure that the main method of blood product safety is pathogen inactivated.Bloodborne pathogens inactivation refers to through physics or change
Learning to do section destroys the structure of virus protein or viral nucleic acid, and virus that may be present in blood is allowed to lose infection, cause a disease
And fertility.The common method of blood inactivation technology have pasteurization, organic solvent/stain release mix (S/D) method,
Membrane filter method, methylene blue photochemical, psoralen photochemical method, riboflavin photochemical method etc..Wherein, methylene blue method is at home
Using relatively wide, this method requires methylenum careuleum to reach enough dosages, can serge blue there is residual toxicity, plasma protein damage that treated
It loses larger.Riboflavin photochemical method is novel safer pathogen inactivated method, and there is inactivation to compose wide, additive safety
Etc. characteristics, application prospect it is more preferable.
Patent CN201621426483.2 discloses a kind of ultraviolet inactivation system based on dual wavelength, including rack, sample introduction
