Abstract

The invention provides an inactivation device and inactivation method for a riboflavin photochemical blood product. The inactivation device can be arranged on an object placing surface (60). The inactivation device comprises a shell (10), a first light-emitting plate (13), a second light-emitting plate (16) and a movable supporting plate (19). The shell (10) is provided with an inactivation compartment (11) and a hatch (12). The inactivation chamber (11) has an extension direction that can be perpendicular to the object placing surface (60). And the hatch (12) is communicated with the inactivation compartment (11) and has a hatch orientation perpendicular to the extension direction. The invention also provides an inactivation method of the riboflavin photochemical blood product. With a mode of combination of riboflavin with light source irradiation, parasite, bacteria, viruses and white blood cells in the blood product are inactivated, so that the inactivation efficiency is improved and thus the safety of the blood product is improved. The structure is simple and the inactivation device is suitable for being used in various occasions.

Description

technical field [0001] The invention relates to the field of medical technology. The invention specifically relates to an inactivation device and an inactivation method for riboflavin photochemical blood products. Background technique [0002] Blood transfusion is one of the main routes of transmission of blood-borne infectious diseases. The existing technology has reduced the blood-borne infectious diseases caused by blood transfusion to a certain extent by improving the screening conditions of blood donors, implementing antibody screening and nucleic acid detection, but due to the limitations of the detection technology itself, there are still potential blood-borne infectious diseases hidden dangers. Among the commonly used blood virus inactivation methods, one is to target pathogen nucleic acid and terminate replication and transcription by destroying nucleic acid. This method includes methylene blue photochemical method, psoralen photochemical method and riboflavin pho...
