Blood identification instrument based on infrared Raman ultraviolet fluorescence super-continuum spectrum

Abstract

The invention discloses a blood identification instrument based on an infrared Raman ultraviolet fluorescence super-continuum spectrum. The blood identification instrument comprises a power supply module, an invisible and infrared spectrum section spectrometer, a two-in and two-out optical fiber, a master control and data analysis system, an integrating sphere, a test tube manipulator, a connecting rod, a guide track, a manipulator motion controller, an outer sample chamber cover plate, a bottom plate, a bracket, an outer light source chamber cover plate, an optical fiber collimation connector, a laser pigtail, a super-continuum spectrum laser, an objective bracket, a microobjective, an objective coupling, an optical collimation lens, a Y-shaped coaxial optical fiber, a first optical fiber coupling, a second optical fiber coupling, a Y-shaped optical fiber and an infrared and ultraviolet narrow linewidth laser. The two-in and two-out optical fiber complex spectrometer is connected by using the Y-shaped optical fiber so as to form the hardware, sectional weighted stack is adopted so as to form the software, and thus data information fusion of an infrared Raman spectrum, an ultraviolet fluorescence spectrum and a super-continuum diffuse comprehensive spectrum can be achieved. The blood identification instrument disclosed by the invention can be applied to automatic identification of whole blood, plasma and serum.

Description

technical field [0001] The invention relates to an instrument and method for human and animal blood classification, in particular to an instrument and method for non-contact identification of blood samples in sealed test tubes based on infrared Raman, 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 no...
