Dual-wavelength-based ultraviolet inactivation system

Abstract

The invention discloses a dual-wavelength-based ultraviolet inactivation system. The dual-wavelength-based ultraviolet inactivation system comprises a machine frame, a sample introduction module, a shake-up module, a first ultraviolet lamp group, a second ultraviolet lamp group and a power supply module, wherein the sample introduction module comprises a pull-out basket frame and a pull-out basket; the pull-out basket is connected with the machine frame; a first guide shaft vertical to the sliding direction of the pull-out basket frame is arranged in the pull-out basket frame; a first bearing is arranged in the pull-out basket; the pull-out basket realizes sliding connection with the first guide shaft through the first bearing; a second guide shaft is arranged in the pull-out basket; the second guide shaft and the first guide shaft are mutually perpendicular in space; the shake-up module is connected with the second guide shaft; the first ultraviolet lamp group is arranged above the pull-out basket; the second ultraviolet lamp group is arranged below the pull-out basket; and the power supply module is arranged at the bottom of the machine frame. According to the scheme, the dual-wavelength-based ultraviolet inactivation system solves the defect that the traditional bagged blood product inactivation equipment performs inactivation incompletely by adopting the design of upper and lower ultraviolet illumination, and enables riboflavin to act on pathogene maximally through proper irradiation of two ultraviolet wavelengths to achieve the inactivation and sterilization effects.

Description

technical field [0001] The invention relates to an ultraviolet inactivation device, in particular to an ultraviolet inactivation system based on dual wavelengths. Background technique [0002] At present, there are four main plasma pathogen fire extinguishing technologies widely used at home and abroad, namely: organic solvent method (S / D method), methylene blue (MB) photochemical method, psoralen (S-59) photochemical method, nuclear Flavin photochemical method. [0003] Riboflavin photochemical treatment (RPT) is a method that has been paid close attention to in the field of inactivation of pathogenic microorganisms in blood components in recent years. Riboflavin, also known as vitamin B2, is one of the water-soluble vitamins necessary for the human body. It consists of a ribitol, an isoalloxazine ring and a sugar side chain respectively. The first part of the isoalloxazine ring in the riboflavin molecule And the 10th nitrogen atom can accept and release hydrogen repeated...
