Device for detecting tumor characters by Raman spectrum

Abstract

The invention discloses a device for detecting tumor character by Raman spectrum. The device comprises a spectrometer module, a sampling module and a control and data processing module, wherein the spectrometer module comprises a laser light source and a Raman spectrometer; the laser light source is used for providing the laser needed by detection; the Raman spectrometer is used for acquiring the Raman spectrum of a sample to obtain a digital signal containing sample molecular information; the sampling module comprises optical fibers and an optical fiber probe; the optical fiber probe is used for collecting the Raman spectrum; the laser light source is connected with the optical fiber probe by the optical fiber, and the optical fiber probe is connected with the Raman spectrometer by the optical fiber; the control and data processing module comprises an embedded microprocessor which is respectively connected with the laser light source and the Raman spectrometer, so that the Raman spectrometer and the laser light source can be controlled in the detection process; and the control and data processing module can be used for judging the tumor character by processing the spectral data after reading the digital signal acquired by the Raman spectrometer. The portable device supports in vivo or in vitro test and is capable of carrying out rapid clinical diagnosis on the tumor character.

Description

technical field [0001] The invention relates to medical detection equipment, in particular to a device for detecting tumor properties by using Raman spectrum. Background technique [0002] Malignant tumors have become one of the major diseases that seriously endanger human health and life in the world, occupying the first place in the mortality rate of urban residents in my country, and seriously threatening human health. For malignant tumors, early detection, early diagnosis, and early treatment are the key to improving the quality of life and prolonging the survival time of patients. [0003] As a molecular spectrum, Raman spectroscopy can reflect the structural information and property changes of biomolecules. Since the process of tumor formation must be accompanied by significant changes in the configuration, conformation and quantity of major biomolecules such as carbohydrates, lipids, proteins, and nucleic acids that constitute cells and tissues, these changes occur e...
