Riboflavin method blood virus inactivation system

Abstract

The invention discloses a riboflavin method blood virus inactivation system. The riboflavin method blood virus inactivation system comprises a box body shell, a temperature adjusting system, a swing system and a control system, a machine frame is fixedly arranged in the box body shell, and a circulation channel is formed between the outer wall of the machine frame and the inner wall of the box body shell; a plurality of ultraviolet lamp panels arranged at intervals are arranged in the machine frame in the height direction of the machine frame; a plurality of lamp beads are arranged on the upper surface and the lower surface of each ultraviolet lamp panel (3); an air outlet and an air inlet which communicate with a cavity are correspondingly formed in the left side wall and the right side wall of the machine frame; the temperature adjusting system comprises a fan I, a fan II, a refrigerating system, an evaporator, an air inlet temperature sensor and an air outlet temperature sensor, the fan I is fixedly arranged on the outer side of the air outlet, and the fan II is fixedly arranged on the top of a circulating air duct; and the swing system comprises a power unit, a swing frame and a movable blood bag bracket. The riboflavin method blood virus inactivation system has the beneficial effects that the structure is compact, lamp beads are prevented from being burnt out, the blood quality is improved, illumination is uniform, the preparation amount is large, and the manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a riboflavin method blood virus inactivation system. Background technique [0002] Blood pathogen inactivation is an important means to ensure blood safety. The inactivation of blood pathogens refers to the destruction of the structure of viral proteins or viral nucleic acids by physical or chemical means, so that the viruses that may exist in the blood lose their ability to infect, cause disease, and reproduce. Common blood inactivation methods include Pasteur disinfection, organic solvent / detergent mixture (S / D) method, membrane filtration method, methylene blue photochemical method, psoralen photochemical method, riboflavin photochemical method Wait. Among them, the methylene blue method is widely used in China. This method requires a sufficient amount of methylene blue, but methylene blue has residual toxicity, and the loss of plasma protein after treatment is relat...

[0003] Although the existing inactivation cabinet can kill the virus in the blood, it still has the following defects: 1, the ultraviolet lamp will release more heat when it is working, so that the temperature in the inactivation cabinet will be raised, and then the blood bag will be damaged. The blood inside heats up, which reduces t
