Abstract

The invention discloses a blood identifying instrument based on infrared Raman supercontinuous integrated diffuse spectra. A power supply module group is used for supplying power to visible and infrared spectrometers, a master control and data analysis system, supercontinuous spectrum and infrared narrow-linewidth lasers and a manipulator motion controller. The master control and data analysis system is used for controlling the visible spectrometer, the infrared spectrometer, the supercontinuous spectrum laser, the infrared narrow-linewidth laser and the manipulator motion controller, receiving spectral data output by the visible spectrometer and the infrared spectrometer via USB interfaces, and carrying out processing and analysis on the received spectral data. The blood identifying instrument has the beneficial effect that information fusion of spectral data is realized since a Y-shaped optical fiber is connected with the two-in-and-two-out optical fiber multiplexed spectrometers in the aspect of hardware and infrared Raman spectra and supercontinuous integrated diffuse laser spectra are subjected to weighted stack in the aspect of software. The robustness of hardware structure and software analysis enables the blood identifying instrument to be applicable to automatic identification of whole blood, 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 combined with supercontinuous integrated laser spectroscopy. 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 detect...
