Abstract

The invention discloses a blood identification method based on ultraviolet fluorescence super-continuum diffuse integrated spectrum. The method comprises six steps of instrument start-up and super-continuum spectrum test sample loading; super-continuum spectrum laser diffuse integrated spectrum testing; fluorescence spectrum test sample loading; ultraviolet laser fluorescence spectrum testing; data analysis and fusion; blood identification and determination and the like. The invention has the following beneficial effects: a Y-type fiber linked two-in-and-two-out fiber multiplex spectrograph is used as hardware, and software adopts weighted stacking of ultraviolet laser fluorescence spectrum and super-continuum diffuse integrated laser spectrum, thus realizing spectrum data information fusion. Due to robustness of the hardware structure and the software analysis, a blood identification machine can be suitable for automatic identification of whole blood, blood plasma and serum.

Description

technical field [0001] The invention relates to a human and animal blood classification instrument and method, in particular to a non-contact identification method for blood samples in sealed test tubes based on ultraviolet fluorescence combined with supercontinuous integrated laser spectrum. Background technique [0002] At present, my country adopts a credit system for the import and export of blood and other various biological materials, but the authenticity of various biological materials cannot be directly tested for various reasons. Especially when it comes to special materials such as blood samples, open contact sampling conditions are often not allowed. On the one hand, the blood sample may be contaminated by the testing operation; on the other hand, the pathogenic factors that the blood sample itself may carry will cause occupational exposure to the testing personnel. In view of the above reasons, it is urgent to develop a non-contact rapid detection method for blo...
